“I have nothing to hide” was once the standard response to the occasional surveillance experience by way of cameras, border checks, or casual questioning by law enforcement.
Privacy used to be considered generally balanced in many countries — at least, in the West — with a few changes to rules and regulations here and there often made only in the name of the common good.
Things have changed, and not for the better.
China’s Great Firewall, the UK’s Snooper’s Charter, the US’ mass surveillance and bulk data collection — compliments of the National Security Agency (NSA) and Edward Snowden’s whistleblowing — Russia’s insidious election meddling, and countless censorship and communication blackout schemes across the Middle East are all contributing to a global surveillance state in which privacy is a luxury of the few and not a right of the many.
As surveillance becomes a common element of our daily lives, privacy is in danger of no longer being considered an intrinsic right.
Everything from our web browsing to mobile devices and the Internet of Things (IoT) products installed in our homes have the potential to erode our privacy and personal security, and you cannot depend on vendors or ever-changing surveillance rules to keep them intact.
Having “nothing to hide” doesn’t cut it anymore. We must all do whatever we can to safeguard our personal privacy. Taking the steps outlined below can not only give you some sanctuary from spreading surveillance tactics but also help keep you safe from cyberattackers.

Data management is at the heart of privacy
Data is a vague concept and can encompass such a wide range of information that it is worth briefly breaking down different collections before examining how each area is relevant to your privacy and security.
Personally identifiable information
Known as PII, this can include your name, physical home address, email address, telephone numbers, date of birth, marital status, Social Security numbers (US)/National Insurance numbers (UK), and other information relating to your medical status, family members, employment, and education.
Why does it matter? All this data, whether lost in different data breaches or stolen piecemeal through phishing campaigns, can provide attackers with enough information to conduct identity theft, take out loans using your name, and potentially compromise online accounts that rely on security questions being answered correctly. In the wrong hands, this information can also prove to be a gold mine for advertisers lacking a moral backbone.
Browsing habits and website visits
Internet activity is monitored by an Internet Service Provider (ISP) and can be hijacked. While there is little consumers can do about attacks at this level, the web pages you visit can also be tracked by cookies, which are small bits of text that are downloaded and stored by your browser. Browser plugins may also track your activity across multiple websites.
Why does it matter? Cookies are used to personalize internet experiences and this can include tailored advertising. However, such tracking can go too far, as shown when the unique identifiers added to a cookie are then used across different services and on various marketing platforms. Such practices are often considered intrusive.

Message and email content
Our email accounts are often the pathway that can provide a link to all our other valuable accounts, as well as a record of our communication with friends, families, and colleagues.
Why does it matter? If an email account acts as a singular hub for other services, a single compromise can snowball into the hijack of many accounts and services.
Online purchases, financial information
When you conduct a transaction online, this information may include credentials for financial services such as PayPal, or credit card information including card numbers, expiry dates, and security codes.
Why does it matter? Cybercriminals who steal financial services credentials through phishing and fraudulent websites, who eavesdrop on your transactions through Man-in-The-Middle (MiTM) attacks or who utilize card-skimming malware can steal these details when they are not secured.
Once this information has been obtained, unauthorized transactions can be made, or this data may also be sold on to others in the Dark Web.
Medical records and DNA profiles
A relatively new entrant to the mix, hospitals now often make use of electronic records, and home DNA services store genetic information belonging to their users.
Why does it matter? The loss of medical information, which is deeply personal, can be upsetting and result in disastrous consequences for everyone involved. When it comes to DNA, however, the choice is ours whether to release this information — outside of law enforcement demands — and it is often the use of ancestry services that release this data in the first place.

What is being done to protect this information?
Businesses that handle data belonging to their customers are being scrutinized more and more with the arrival of regulatory changes such as the EU’s General Data Protection Regulation, designed to create a level playing field and stipulate adequate security measures to protect consumer privacy and data.
Companies will often encrypt your information as part of the process, which is a way to encode information to make it unreadable by unauthorized parties.
One way this is achieved is by using SSL and TLS certificates that support encryption on website domains. While usually a paid service, Let’s Encrypt also offers free SSL/TLS certificates to webmasters who wish to improve their websites’ security. (Unfortunately, this has also led to the adoption of SSL by fraudsters.)
End-to-end encryption is also becoming more popular. This form of encryption prevents anyone except those communicating from accessing or reading the content of messages, including vendors themselves.
Following Snowden’s disclosure of the NSA’s mass surveillance activities, end-to-end encryption has been widely adopted by many online communication services. Privacy advocates may cheer, but governments and law enforcement agencies have not rejoiced at the trend — and a political battlefield has emerged between tech vendors and governments that are attempting to enforce the inclusion of deliberate backdoors into encrypted systems.
It is up to us to make use of any privacy-enabling technology we have at hand. Below are some guides with simple steps to get you started.

Browser basics and Tor
Searching the web is a daily activity for many of us, and as such, it is also a hotbed for tracking and potential cyberattacks.
The most commonly-used browsers are Google Chrome, Apple Safari, Microsoft Edge, Opera, and Mozilla Firefox. However, you should consider using Tor if you want to truly keep your browsing private.
The Tor Project is an open-source browser that is privacy-focused. The software creates tunnels rather than establishing direct connections to websites, which prevents users from being tracked through traffic analysis or IP addresses.
Not to be confused with the Dark Web — although required to access it and .onion domains in general — Tor is legal and is often used by the privacy-conscious, including journalists, activists, and NGOs.
The Tor browser can be slightly slower than traditional browsers, but it is still the best choice for secure browsing.
Desktop and mobile versions of the Tor browser are also available: desktop, the iOS Onion Browser, and Orbot: Tor for Android.
Also: Firefox to add Tor Browser anti-fingerprinting | Why you’re using Tor wrong
Secure other browsers
If you are more comfortable using Chrome, Safari, Firefox, Microsoft Edge, or another browser, there are still ways to improve your security without implementing major changes to your surfing habits.
Cookies: Clearing out your cookie caches and browser histories can prevent ad networks from collecting too much information about you. The easiest way to do so is to clear the cache (Firefox, Chrome, Opera, Safari, Edge).
You can also set your preferences to prevent websites from storing cookies at all. In order to do so, check out these guides for Firefox, Chrome, Opera, Safari, and Edge.
HTTP v. HTTPS: When you visit a website address, you will be met with either Hypertext Transfer Protocol (HTTP) or Hypertext Transfer Protocol Secure (HTTPS). The latter option uses a layer of encryption to enable secure communication between a browser and a server.
The most important thing to remember is while HTTPS is best used by default in general browsing, when it comes to online purchases it is crucial to protecting your payment details from eavesdropping and theft.
It is still possible for payment details to be stolen on the vendor’s side, but to reduce the risk of theft as much as possible you should not hand over any important information to websites without HTTPS enabled. (It is estimated that shopping cart conversion rates increase by 13 percent with HTTPS enabled, which should encourage webmasters to use the protocol, too.)
To find out whether HTTPS is enabled, look in the address bar for “https://.” Many browsers also show a closed padlock.
Google’s search engine, alongside other major options such as Yahoo! and Bing, make use of algorithms based on your data to provide “personalized” experiences. However, browsing histories and search queries can be used to create user profiles detailing our histories, clicks, interests, and more, and may become invasive over time.
To prevent such data being logged, consider using an alternative that does not record your search history and blocks advertising trackers. These options include DuckDuckGo, Qwant, and Startpage.
If you wish to stay with your current browser you can use software that bolts-on to your browser to enhance the privacy and security of your surfing activities.
HTTPS Everywhere: Available for Firefox, Chrome, and Opera, HTTPS Everywhere is a plugin created by the Tor Project and Electronic Frontier Foundation to expand HTTPS encryption to many websites, improving the security of your communication with them.
Disconnect: Another worthy addition to the list, Disconnect provides a visual guide to websites that are tracking your activity. Invisible trackers which monitor you and may also expose you to malicious content can be blocked. Disconnect is available for Chrome, Firefox, Safari, and Opera.
Facebook Container: In a time where Facebook has come under fire for its data collection and sharing practices time after time, Mozilla’s Facebook Container application is a worthwhile plugin to download if you are worried about the social media network tracking your visits to other websites. The plugin isolates your Facebook profile and creates a form of browser-based container to prevent third-party advertiser and Facebook tracking outside of the network.
Blur: Blur, available for Firefox and Chrome, is an all-around valuable plugin to protect your privacy and security. While the add-on can be used as a password manager and generator, ad blocking, and encryption, the true value is the use of “masked cards” in the premium version of the software. When data breaches occur, financial information is often the target. With this plugin, however, throwaway virtual cards are used with online vendors in replacement for the direct use of your credit card data, keeping it safe should a cyberattack occur.
Privacy Badger: Last but certainly not least, the Electronic Frontier Foundation (EFF)’s Opera, Firefox, and Chrome-supporting plugin Privacy Badger is focused on preventing ad networks from tracking you. The software monitors third parties that attempt to track users through cookies and digital fingerprinting and will automatically block those which use multiple tracking techniques. The plugin also includes color-coded indicators of domain tracking scripts.

Public Wi-Fi: A security risk?
There is no denying that public Wi-Fi hotspots are convenient. However, you may be placing your privacy and security at risk if you choose to use one while on the move.
The problem with them is simple: As you do not need authentication to access them, neither do cyberattackers — and this gives them the opportunity to perform what is known as Man-in-The-Middle (MiTM) attacks in order to eavesdrop on your activities and potentially steal your information, as well as manipulate traffic in a way to send you to malicious websites.
Hackers may be able to access the information you are sending through the Wi-Fi hotspot, including but not limited to emails, financial information, and account credentials. Hackers may also set up their own rogue honeypot Wi-Fi points that appear legitimate whilst only being interested in stealing the data of those who connect to it.
It is best not to use a public, unsecured Wi-Fi connection at all if possible. An alternative and far more secure method is to use a mobile 4G/LTE connection through your own mobile device.
If you need an internet connection for a device other than your smartphone, an easy way to accomplish this is to set up your mobile device as a mobile Wi-Fi hotspot itself. You can usually find this option in your main scroller menu, or under Wi-Fi settings.
There are other precautions you can take to make a public Wi-Fi hotspot safer — but it’s never devoid of risk.
When you connect to a new Wi-Fi hotspot on Microsoft Windows machines, make sure that you select “Public” when the option appears, as this will enable the operating system to turn off sharing; turn off the Wi-Fi connection when you do not need it, enable firewalls, and try to only visit websites with HTTPS enabled.
In addition, do not use the Wi-Fi hotspot to access anything valuable, such as an online banking service.
One of the most important layers of security to implement is the use of a virtual private network (VPN) if accessing a public Wi-Fi hotspot — and the use of a trustworthy VPN should be implemented across all your devices, no matter your connection type.

VPNs: Why, when, and where?
A virtual private network is a way to create a secure tunnel through the inherently insecure internet. Data packets are encrypted before they are sent to a destination server, which also results in IP addresses and your location becoming hidden. Many VPNs will also include a ‘kill switch’ that cuts off your internet access temporarily if connections drop in order to keep your online activity secure.
VPNs have now entered the mainstream. Many users will only adopt these services to access geolocation-blocked content — such as websites and apps banned in select countries — for example, a user in the United States could make themselves appear to be located in the United Kingdom, and vice versa.
However, VPNs have also surged in popularity in response to increased surveillance, making their use a popular option for activists or those in countries ruled by censorship.
(For a more detailed look at how VPNs operate, check out our guide.)
VPNs are not a silver bullet for security; far from it, but they can help mask your online presence. It is worth noting, however, that VPN usage is banned in some countries.
Free vs. premium VPNs
Premium, paid services are often more trustworthy. Free options are often slower and will offer limited bandwidth capacity. VPNs cost money to run and so providers will also require users of free services to agree to alternative means for them to turn a profit — and this may include tracking and selling your data.
Remember, when you are using a free service, whether it’s a VPN or Facebook, you are the product and not the customer.
(If you’re technically able, you could also set up your own private VPN. A handy set of instructions can be found here.)
Which VPN should I use?
The most important element to consider when deciding on a VPN is trust. Using a VPN requires all your traffic to go through a third-party. If this third-party VPN is unsecured or uses this information for nefarious reasons, then the whole point of using a VPN for additional privacy is negated.
Conflicts of interest, VPN providers being hosted in countries of which governments can demand their data, and sometimes less-than-transparent business practices can all make finding a trustworthy option a complex and convoluted journey.
However, to make this trip easier, our favorites include NordVPN, Private Internet Access, ExpressVPN, and TorGuard. CNET has also provided an up-to-date directory of good VPN options.

Passwords and vaults
This kind of advice is repeated ad nauseam but it is worth saying again: using complex passwords is the first line of defense you have to secure your online accounts.
Thankfully, many vendors now actively prevent you from using simple combinations that are easy to break, such as QWERTY12345 or PASSWORD123, with dictionary-based and brute-force attacks.
However, it is difficult to remember complicated password credentials when you are using multiple online services, and this is where password vaults come in.
Password managers are specialized pieces of software used to securely record the credentials required to access your online services. Rather than needing to remember each set of credentials, these systems keep everything in one place, accessed through one master password, and they will use security measures such as AES-256 encryption to prevent exposure.
Vaults may also generate strong and complex passwords on your behalf, as well as proactively change old and weak ones.
It is true that many popular password managers and vaults do have vulnerable design elements that can be exploited on already-compromised machines, but when you balance risk, it is still recommended to use such software. Vendors with the best ratings include LastPass, Keeper, and Blur, but for a full range, check out CNET’s password manager directory.
Enable Two-factor authentication (2FA)
Two-factor authentication (2FA) is a widely-implemented method of adding an extra layer of security to your accounts and services after you have submitted a password.
The most common methods are via an SMS message, a biometric marker such as a fingerprint or iris scan, a PIN number, pattern, or physical fob. Using 2FA does create an additional step to access your accounts and data.
How to enable 2FA: Facebook | Twitter | Instagram | Snapchat | Apple iOS | Google | Microsoft | Amazon
Tutorials for other major services can be found at Turn it On.
You can also use standalone mobile apps to add 2FA to websites. Google Authenticator, available for Android and iOS, is a popular option, as well as Authy.

Secure your mobile devices
Mobile devices can act as a secondary means of protection for your accounts through 2FA, but these endpoints can also be the weak link that completely breaks down your privacy and security.
Both Apple iPhones and mobile devices based on Google’s Android operating system have sold by the millions. Android has maintained the lion’s share of the global smartphone and tablet market for years, but due to its popularity, the majority of mobile malware samples are geared towards this OS.
The open-source nature of Android has also opened the way for hackers to search for vulnerabilities in its code, but to combat this, Google does run a bug bounty program and consistent security patch cycle.
iOS, in contrast, is a proprietary operating system and iPhones are generally considered more secure — despite the emergence of security flaws on occasion, which are almost laughable.
(Google has previously said that Android security is now as good as iOS, but we are still waiting to see the real-world evidence of this claim.)
Patch, patch, patch
The first and easiest way to keep mobile devices on either platform secure is to accept security updates when they appear over the air. These patches resolve new bugs and flaws, as well as sometimes provide performance fixes, and can keep your device from being exploited by attackers.
To check your device is up to date on iOS, go to Settings > General > Software Update. On Android, go to Settings > Software Update.
Lock it down
It sounds simple, but many of us don’t do it — make sure your mobile device is locked in some way to prevent its physical compromise.
You can turn on your iPhone‘s Passcode feature to enter a four or six-digit passcode, as well as select the ‘custom’ option to set either a numeric or alphanumeric code. On iPhone X and later, go to Settings > Face ID & Passcode, while on earlier iPhone devices, go to Settings > Touch ID & Passcode. If TouchID is not a feature on your iPhone, the menu option will simply show Passcode.
On Android, you can choose to set a pattern, PIN number, or password with a minimum of four digits. You can choose by tapping Settings > Security & location/Security > Lock Screen.
Face recognition, iris scanning, and fingerprints are biometric authentication options found on modern iPhones and Android devices. These services can be convenient, although it is worth noting that in the US, law enforcement may be able to force you to unlock your devices as biometrics are not protected under the Fifth Amendment.
Find your phone
We want to stop ourselves from being monitored without consent, but some technologies can be beneficial for tracking down our own lost or stolen property.
Find my iPhone is a security feature for iOS devices that you can enable to allow you to track your device through iCloud. The system also includes a remote lock to prevent others from using your iPhone, iPad or iPod Touch in the case of theft.
In order to enable Find my iPhone, go to Settings > [your name] > iCloud. Scroll to the bottom to tap Find my iPhone, and slide to turn on.
Google’s Find My Device can be used to ring a missing device, remotely secure your smartphone, and also wipe all content on your stolen property. The service is automatically made available by default once a Google account is connected to your device but it does require the device to be turned on, to have an active internet connection, and to have both location and the Find My Device feature enabled.
In order to do so, open Settings > Security & Location/Security > Find My Device.

Other privacy settings
For the iPhone
USB Restricted Mode: A handy security feature introduced in iOS 11.4.1, USB Restricted Mode prevents USB accessories from automatically being able to connect to an iPhone if an hour has elapsed since the last time it was unlocked. In order to enable, go to Settings > Touch ID/Face ID > USB Accessories.
Disable the option to enable unknown developers/apps: If there have been apps you simply had to install outside of Google Play, make sure the “Unknown Sources” or “Install Unknown Apps” option is not left open afterward. Sideloading isn’t necessarily a problem on occasion but leaving this avenue open could result in malicious .APKs making their way onto your smartphone.
To disable it, select Settings > Security > Unknown Sources. On the later Android models, the option is usually found in Apps > Top-right corner > Special access.
Encryption: Depending on your smartphone’s model, you may have to enable device encryption, or some will be encrypted by default once a password, PIN, or lock screen option is in place. If you have such a device you can generally encrypt your smartphone through Settings > Security > Encrypt Device.
Other models, such as the Samsung Galaxy S8, do not have this option as encryption is enabled by default but you can choose to encrypt accompanying SD cards by going to Biometrics and security > Encrypt SD card.
You can also choose to enable the Secure Folder option in the same settings area to protect individual folders and files.

Rooting your device to allow the installation of software that has not been verified by vendors or made available in official app stores has security ramifications. You may not only invalidate your warranty but also open up your device to malware, malicious apps, and data theft.
An example of this is KeyRaider, a malicious campaign uncovered by Palo Alto Networks in 2015. The malware specifically targeted jailbroken iOS devices, leading to the theft of 225,000 Apple accounts and their passwords.

Encrypt your messages
There was once a time when Pretty Good Privacy (PGP) was one of only a handful of options available to secure and encrypt your online communication that existed. PGP is a program that can be used for cryptographic protection, however, PGP is complicated to set up and use and there are other options out there that are more palatable to the average user.
If you still wish to use PGP, the Electronic Frontier Foundation has useful guides on its implementation for Windows, MacOS, and Linux. Vulnerabilities were found in the system last year but have since been patched.
keybase.io, an open-source app built based on PGP for mobile and desktop systems available for macOS/iOS, Android, Linux, and Windows, is another option for making use of PGP and end-to-end encryption without the technical difficulties usually involved.
There are a number of encrypted messaging applications:
Signal is widely regarded as the most accessible, secure messaging service in existence today. Available for Android, iOS, MacOS, and Windows, the free app — developed by Open Whisper Systems — implements end-to-end encryption and no data is stored by the company’s servers, which means that none of your conversations can be seized or read by law enforcement or hackers.
In order to use the service, you will need to tie a phone number to the app. You can also use Signal to replace traditional SMS messaging, but the same encryption and protections do not apply unless both recipients are using Signal.
WhatsApp is an alternative messaging app, which completed a rollout of end-to-end encryption across all compatible devices in 2016.
Available for Android, iOS, Windows Phone, Mac, Windows, and desktop, the messaging app is a simple and secure means to conduct chats between either a single recipient or a group. Having grown even more popular in recent years and now boasting over one billion users, WhatsApp is certainly worth downloading to replace traditional chat apps. However, to tighten things up, make sure you visit the Chat Backup option in “Chats” and turn it off.
Apple’s iMessage, a communications platform that comes with Mac and iOS products, is another option if you want to secure and protect your digital communications.
However, this does come with some caveats.
Messages are encrypted on your devices via a private key and cannot be accessed without a passcode. However, if you choose to back up your data to iCloud, a copy of the key protecting these conversations is also stored — and this has the possibility of being accessed by law enforcement.
In order to keep your messages truly private, turn off the backup option. Apple will then generate an on-device key to protect your messages and this is not stored by the company.
In addition, only conversations taking place between iPhones — rather than an iPhone and Android device, for example — are encrypted.
Facebook Messenger is not encrypted by default. The chat service does, however, have a feature called “Secret Conversations ” on iOS and Android — but not the standard web domain — which is end-to-end encrypted.
In order to start a secret conversation, go to the chat bubble, tap the “write” icon, tap “Secret,” and select who you want to message. You can also choose to set a timer for messages to vanish.
A word of warning, however: Not only is Facebook constantly under fire for its attitude to the privacy and security of its users and their data, but US law enforcement is reportedly attempting to pressure the social network into planting a backdoor into Facebook Messenger to monitor conversations. With other end-to-end options available, it’s not worth the risk.
Telegram, which received over three million new signups during the Facebook outage in March 2019, is another popular chat application worth noting as many presume chats made through this app are automatically secure and encrypted — which is not the case.
Available for Android, iOS, Windows Phone, macOS, Linux, Windows, and desktop, Telegram is not encrypted by default but does have a “Secret Chat” option that is end-to-end encrypted and kept away from the Telegram cloud. These particular chats are device-specific and include a self-destruct option.
It is also worth keeping an eye on the rumored, upcoming Facebook Messenger, WhatsApp, and Instagram merger. Facebook CEO Mark Zuckerberg has reportedly ordered end-to-end encryption services to be added to the combined platform to create secure, cross-app messaging, which may make the combined service a future possibility for secure chats. However, the integration is not expected to be ready for commercial release until 2020.

Mobile application sources and permissions
No matter which mobile operating system you have adopted, downloading apps from verified, trusted sources such as Google Play and Apple’s App store is always the best option to maintain your security and privacy.
However, the permissions you give an installed app are also important.
Apps can request a variety of permissions including sensor data, call logs, camera and microphone access, location, storage, and contact lists. While many legitimate apps do require access to certain features, you should always make sure you are aware of what apps can access what data to prevent unnecessary security risks or information leaks.
CCleaner, Pokemon Go, Meitu, and Uber have all come under fire for privacy-related issues in the past and the problem of data collection and extended business permissions will likely carry on in the future.
To be on the safe side, any time you no longer need an application, you should also simply uninstall it.
Mobile malware is far from as popular as malicious software that targets desktop machines but with these variants infecting Android, iOS, and sometimes making their way into official app repositories, they are worth a mention.
The types of malware that can hit your mobile device are varied, from Trojans and backdoors to malicious code that focuses on the theft of valuable information, such as online banking credentials.
The most common way that such malware can infiltrate your smartphone is through the installation of malicious apps, which may actually be malware, spyware, or adware in disguise.
It’s recommended that you download and install an antivirus software solution for your mobile device, however, you will probably be safe enough as long as you do not jailbreak your phone and you only download app .APKs from trusted sources, such as Google Play or the Apple App Store. However, malicious apps do sneak into these official stores as well.

Many email providers now encrypt email in transit using TLS, but there are few email services, if any, which you can truly consider 100 percent “secure” due to government laws, law enforcement powers, and the difficulty of truly implementing strong encryption in email inboxes beyond using PGP to sign messages.
However, ProtonMail is worth considering. The open-source email system is based in Switzerland and therefore protected under the country’s strict data protection laws. Emails are end-to-end encrypted which prevents ProtonMail — or law enforcement — from reading them. In addition, no personal information is required to open an account.

Reduce your online footprint
Now that you’ve begun to take control of your devices, it is time to consider what data is floating around the internet that belongs to you — and what you can do to prevent future leaks.
One of the first places to travel to is Troy Hunt’s HaveIBeenPwned service. The free search engine (of sorts) can be used to check your email accounts and linked online services for the exposure of credentials caused by data leaks. If you find you have been ‘pwned,’ stop using all the password combinations involved immediately — not only in the case of the compromised account but across the board.
Google privacy checks
If you are a user of Google services, the Privacy checkup function can be used to stop Google from saving your search results, YouTube histories, device information, and for you to decide whether you are happy for the tech giant to tailor advertising based on your data.
Make sure you also take a look at your main Google Account to review security settings and privacy measures. The Security checkup page also shows which third-party apps have access to your account and you can revoke access as necessary.

Social networks can be valuable communication tools but they can also be major sources of data leaks. It is not just friends and family that might be stalking you across social media — prospective employers or shady characters may be doing so, too, and so it is important for you to lock down your accounts to make sure only the information you want to be public, is public.
To begin locking down your account, go to the top-right corner, click the downward arrow, and choose “Settings,” which is where the majority of your options for privacy and account safety are based.
Security and login
Under this tab, you can choose to enable 2FA protection, view the devices in which your account is actively logged on, and choose whether to receive alerts relating to unrecognized attempts to log in.
Your Facebook information
Review activities: Under Activity Log, you can review all your activity across the social network, including posts published, messages posted to other timelines, likes, and event management. You can use the “edit” button to allow something on a timeline, hide it, or delete it outright — a handy function for wiping clean your older timeline.
Download data: Under this tab, you can choose to download all the data Facebook holds on you.
Privacy Settings and Tools: Here, you can choose who can see your future posts. For the sake of privacy, it is best to set this to friends only, unless you are happy for such content to automatically be made public.
How people can find and contact you: You can tighten up your account by also limiting who can send you friend requests, who can see your friend lists, and whether people are able to use your provided email address or phone number to find your profile. A particular feature you may want to turn off is the ability for search engines outside of the network to link to your Facebook profile.
Location: Turn off this to prevent Facebook from gathering a log of your location history.
Face recognition: Another feature you should consider turning off — it’s unnecessary.
Apps and websites: Under this tab, you can see a list of third-party services that have been logged into using your Facebook credentials and whether they are active.
Ad Preferences, advertisers: A settings option that has been heavily expanded upon since the Cambridge Analytica scandal, in this section, you can review what Facebook believes are your interests, a list of advertisers that “are running ads using a contact list that they or their partner uploaded which includes information about you,” and you can manage personalized ad settings — at least, to a point.
Your interests: If you select this tab you will see topics, such as property, finance, food, and education, which are collated based on ads or promotional material you have previously clicked on. In order to remove a topic, hover over the option and select the “X” in the top right. The same principle applies to the “Advertisers” tab.
Your information: There are two tabs here that are both relevant to your online privacy and security. The first tab, “About you,” allows you to choose whether Facebook can use your relationship status, employer, job title, or education in targeted advertising. The second tab, “Your categories,” includes automatically generated lists of topics that the social network believes are relevant for ad placement — all of which can be hovered over and removed.
Ad Settings: To further thwart targeted ads, consider saying no to all the options below.
Another section to mention is under the “About Me” tab in Facebook’s main account menu. Here, you can choose whether to make information public (whether globally or to your friends), or only available to you. This information includes your date of birth, relationship status, contact information, and where you’ve lived.
Under the “Settings” tab there is a variety of options and changes you should implement to improve the security of your account.
Login verification: After you log in, Twitter will ask you for additional information to confirm your identity to mitigate the risk of your account from being compromised.
Password reset verification: For added security, this requires you to confirm your email or phone number while resetting your password.
Privacy and safety: You can deselect location tracking and stop your locations being posted at the same time you send out a tweet, and there is also an option for removing all past location data from published tweets in your history.
In this section, you will also come across “Personalization and data,” which allows you to control — to an extent — how the social network personalizes content, collects data, and what information is shared with third-parties. You have the option to choose not to view personalized adverts, but the main setting you need to be aware of is for sharing.
Described by Twitter as an option to permit the company to “share non-public data, such as content you’ve seen and your interests, with certain business partners for uses like ads and brand marketing,” you should consider saying no.
Apps and devices: Under this tab, you can see what third-party services, if any, are connected to your account, as well as what devices your Twitter account is actively logged into.
There is also an interesting section under “Your Twitter data.” Once you have entered your password, you can see Twitter’s compiled collection of interests and advertising partners based on your activities.
It is also possible to request your full data archive under the main Settings tab.
To give your Instagram account a privacy boost, there are a few changes you can implement.
By default, anyone can view the photos and videos on your Instagram account. By going to Settings and then Account Privacy, you can change this to ensure only those you approve of can see your content.
If your account is public, then anyone can view and comment on your images and videos. However, you can block people you would rather not interact with.

The Internet of Things
The Internet of Things (IoT) started off with mobile devices, including our smartphones, tablets, and smart watches. Now, IoT encompasses everything from smart lights to voice-controlled smart speakers and home hubs, such as Google Home and the Amazon Echo.
Here are some tips to improve the security of your connected home and prevent your products from being compromised, your information stolen and your IoT products from being added to botnets:
- Keep IoT devices password protected. Default credentials — unfortunately often still in play when it comes to IoT vendors — are an easy way for hackers to compromise a device. The first and easiest way to protect your devices is to change these credentials ASAP.
- Making sure your IoT device firmware, as well as your router software, is to up-to-date is also a key factor.
- Consider running all your IoT devices on a separate home network. Therefore, in the case of compromise, the damage can be limited.
- If your IoT device does not require an internet connection to run, then disable it. (Unfortunately, this is rare nowadays)
- If you no longer need an IoT device or have upgraded, perform a factory reset and remove older devices from your network.
- Always check the default settings on new products. It may be that default options — such as the implied consent for usage data and metrics to be sent to the vendor — will benefit the vendor, but not your privacy.
Just do it
The threats to our privacy and security are ever-evolving and within a few short years, things can change for the better — or for the worse. It is a constant game of push-and-pull between governments and technology giants when the conversation turns to encryption; cyberattackers are evolving and inventing new ways to exploit us daily, and some countries would rather suppress the idea of individual privacy, rather than protect it.
Thankfully, the threat to our privacy has now been acknowledged by technology companies and many organizations, both for and non-profit, have taken it upon themselves to develop tools for our use to improve our personal security — and it is now up to us to do so.
