The Updated Guide to Online Privacy and Security

Right after food, water, and air, I (personally) think the internet is one of the best things to happen to man. There are about 7.7 billion people on earth and according to WeAreSocial.com, over 4 billion people use the internet in 2019. That’s more than half of the world’s population.

The internet is a beautiful place; a medium to obtain & exchange information, work, have fun, make money, communicate, meet people, learn stuff, and do a whole lot more. However, despite the good that the internet has to offer, things can get really ugly as well.

In so many different ways, people have been scammed on the internet, their monies (and identities) have been stolen, accounts have been compromised and so on. And these things are avoidable. Carefully go through this guide to have a full understanding of how you can stay protected on the internet — on mobile & mobile apps, PC & desktop software, etc.

A. General Security and Authentication

i. Protect yourself from other individuals

Before now, a good number of internet users accessed the web via laptops and desktops. Things are quite different now as smartphones and mobile apps have disrupted PC. And since, unlike PC, smartphones can get stolen or misplaced easily, the very first step of securing your online accounts is creating strong passwords, PINs, and patterns. Biometric authentication methods like fingerprint, Face ID, Iris scanning, and Palm Unlock are also other secure ways of protecting your smartphone and mobile app.

There are times when you aren’t sure if your account passwords have been compromised or not. There are certain tools (like Google Chrome’s Password Leak Detection) that help you figure out which of your passwords have been compromised in data breaches.

The list below contains links to useful information, tutorials, and guides that’ll help you strengthen your mobile and app security. And ultimately, protect you from any harm on the internet.

ii. Creating Strong Passwords

Online security and privacy

Anything worth doing is worth doing well, they say. The same applies to creating passwords to safeguard your accounts on the internet. You shouldn’t just create passwords for the sake of it. Your password should be “strong”. It should contain a balanced mix of certain elements and ultimately, be very difficult to hack, guessed, or bypass. And yes, there are some passwords you should NEVER use to secure your accounts. Check them out.

If you’re having a hard time creating a strong password, you should check out our detailed guide on creating strong passwords. Alternatively, you can use password managers — software/apps that suggest strong passwords for your online accounts and also helps manage all your passwords so you don’t have to always remember them.

iii. Two-Factor Authentication — Passwords aren’t enough

Sometimes, it’s not even enough having a strong password; you should further beef up your mobile account’s security via 2-Factor Authentication (also called 2FA or 2-Step Verification). Enabling 2FA in your online accounts will require you input some sort of code (in addition to your password) which would be sent to your phone number as a text, to a physical token, or the authenticator app on your smartphone.

We have put together a comprehensive guide on everything you need to know about 2-Factor Authentication — when, why and how to use it to secure your account online.

B. Online & Web Privacy

Because the internet is filled with hackers, spammers, sniffers and prying eyes with evil intents waiting to steal your data at every chance they get. This is why it is important to keep yourself (and your information) protected at all times.

i. VPN & Proxies

As earlier mentioned, the internet is one place where you want your privacy respected on all fronts. However, this is something you need to pay keen attention to because the hackers are also not sleeping. One way to keep your online privacy strong is by concealing your internet traffic. And you can achieve that using VPN and Proxies.

Asides from bypassing geo-restrictions, VPNs and Proxies are also brilliant ways to conceal your identity from evil eyes on the internet.

ii. DNS-over-HTTPS

Hackers, spoofers, and individuals aren’t the only ones that constantly lurk on the internet to steal your data. Corporations do it too. Sometimes, your internet service provider (ISP) harvests personal data about your activities on the web and sells to third-parties —who in turn use such info for advertising targeting— without your consent. Not all ISPs do this but the truth is, there’s really no way for you to find out if they do… or not.

What you can do, however, is to use privacy-focused technologies like DNS-over-HTTPs to protect your personal privacy on the web. You can further read about such technologies and how to use them to safeguard yourself and your data on the web.

iii. HTTPS & SSL certificates

When you surf the web in your browser, some websites URL start with http:// and some, https://. The additional “S” has a meaning to it and you should ensure that whatever website you’re surfing on the world wide web has a https:// at the beginning of the URL.

https

The extra S stands for Secure Sockets Layer (SSL) and is an indication that your connection with the website is private and whatever information you provide on the site cannot be intercepted by a third-party who may want to use it for fraudulent activities. Whenever you’re surfing a website that doesn’t have the SSL certificate, some browsers (especially Chrome) will alert you that the website isn’t secure. Whenever you this warning, make sure you do not provide sensitive information on the website.

not secure

SSL (Secure Sockets Layer) is the standard technology for keeping an internet connection secure and safeguarding any sensitive data that is being sent between two systems (like a website and a server) so as to prevent criminals from reading and modifying any information transferred, including potential personal details, credit card details, bank login credentials, passwords, etc.

HTTPS and SSL certificates generally slap an extra layer of security to your online activities. can learn more about HTTPS and SSL certificates in the links below.

iv. Privacy-focused Browsers & Search Engines

Not sure if you know this but the moment you log onto the internet, you leave a trace that tells a lot about you to certain people and corporations. Your browser, for example, knows more than you think. Asides the fact that it (your browser) takes note of your browsing history, other data like location information, operating system details, plugins installed, time zone the computer is set to, language, screen size and other information are garnered through a process known as “fingerprinting”.

Some browsers are also not generally secure and allow hackers and third-parties access your data so easily. That’s why should consider using privacy-focused browsers. These privacy-focused web browsers limit ads, incessant spam, monitoring, and tracking to the barest minimum.

About search engines, they also collect and harvest a lot of your personal information. That’s the (hidden) price you pay for using their services for free. The solution to keeping your private information private when searching for information online is to use privacy-focused search engines — DuckDuckGo is a good example.

v. Disposable Email Providers

Another service that you can use to beef up your online privacy & security is Disposable emails. Also known as “Throw-away email”, “Tempmail”, “Fake-mail”, or “Trash mail”, Disposal email providers offer these service that allows you receive emails at a temporary address that self-destructs after a certain time elapses. No sign-up or password is required.

Disposable email also helps you avoid malicious spam messages that pile up in your inbox. Another use case of disposable emails is when some retailers, websites, and blogs ask you to register before you view certain content, post comments or download something but eventually end up spamming your inbox.

vi. Phishing and Scams

For noobs and newbies, phishing is when hackers or evil perpetrators maliciously keep (and operate) a false website or send a false e-mail with the intent of masquerading as a trustworthy entity with the intent of acquiring sensitive information such as usernames, passwords, login credentials, credit card details, etc.

C. Mobile Security

Because the majority of the online activities (shopping, social media, gaming, surfing, movies, streaming, etc) happen on our smartphones and tablets through mobile apps, it is important to learn how to keep your privacy intact while using them.

i. App permissions

App permissions

When you newly install an app, it mostly requires you to approve certain permissions. These permissions usually give these apps access to personal & private information like your location, files, microphone & mic recordings, and other data that can be used to track you.

The links below will navigate you through things you need to do to keep your private info from the reach of certain apps.

ii. Pop-up Ads

Pop-ups and malware are another thing you should keep an eye out for. These are malicious apps designed to steal your information and also cause damage to your device. Pop-ups drain your phone’s battery, increase your device temperature, and generally make your device run slower. Worst part is that they are “stubborn” i.e. sometimes very difficult to uninstall or remove fro your device.

iii. Geo-tagging

Despite the fact that the average internet user is now more privacy-conscious about the type of information shared online, we still subconsciously give out certain (sensitive) data without even realizing it.

Geo-tagging is the process of attaching location information to media files like photos and videos. When a media file is “geo-tagged”, it basically means that the device (digital camera, smartphone, tablet, etc.) that captured the file has embedded GPS coordinates in the file metadata.

Although geo-tagging a photo has some useful applications like helping you organize pictures in your gallery based on location, it also comes with its associated (privacy) risks too. A stranger can download your pictures on the internet, extract GPS coordinates and track you.

D. Banking, Payments & Mobile Money

The rise of eCommerce, cryptocurrency, mobile money, fintech apps, payment apps, virtual cards and the like have subsequently increased how much people transact over the internet. In Africa and across the globe. Equally, the number of time people have been scammed while transacting online and their assets stolen have likewise increased.

Since the majority of transactions carried out online are performed using credit and debit card, it is important to know the anatomy of your banking (debit and credit) cards, measures you can take to avoid being defrauded, as well as what you should do if your card/logins are stolen.

As an added layer of security when transacting online, ensure that extra authentication steps like 2-Factor Authentication and One-Time Password/PIN (OTP) are enabled on your banking and payment apps.

The articles linked below contain everything you need to know about staying safe while transacting online.

E. Email Protection

Email is one of the most used media of communication, both for personal and business purposes. There are about 4 billion email users worldwide and over 293 billion emails are sent each day (according to 99firms.com).

As such, email (and email accounts) are mostly targetted by hackers and spammers. There are a lot of security methods listed above that helps protect your emails but we’d be linking more email security resources and tips below.

Emails are secure, but not always. If you had previously granted any third-party apps, software or developers access into your inbox, they can read your emails. So you should review the permissions you might have given to third-party apps in the past. You might also want to confirm that your email provider offers end-to-end encryption.

F. Social Media

Everyone uses social media but not everyone is using it safely. By safely, we mean what are the things your social media platforms know about you? Do they collect more data than you permit them to? What type of information does your social media platforms collect from your (and behind your back)? Are your social media accounts well-protected from hackers? So many questions.

Luckily, there are answers to all of them. In this era where many social media platforms have been caught harvesting and selling their user data to the highest bidder, using social media safely and being conscious of what data they obtain from you is quite important.
