What is internet security?
Internet security consists of a range of security tactics for protecting activities and transactions conducted online over the internet. These tactics are meant to safeguard users from threats such as hacking into computer systems, email addresses, or websites; malicious software that can infect and inherently damage systems; and identity theft by hackers who steal personal data such as bank account information and credit card numbers. Internet security is a specific aspect of broader concepts such as cybersecurity and computer security, being focused on the specific threats and vulnerabilities of online access and use of the internet.
Phishing
Phishing is a type of social engineering where an attacker sends a fraudulent message designed to trick a human victim into revealing sensitive information to the attacker or to deploy malicious software on the victim's infrastructure like ransomware.
Hacking
A security hacker is someone who explores methods for breaching defenses and exploiting weaknesses in a computer system or network.
Hacking is an interesting option since it is far less likely to affect you as an individual, even though the term is pretty much shorthand for “doing evil on the internet”. Many hackers are often professionals who go after high-profile targets.
It goes without saying that the average computer user is unlikely to be hacked. Where hacking might affect you, however, is when companies that you do business with are hacked. This is known as a “breach” and there’s a good chance it’s already happened to you or someone you know at some point. In this case, some of your information is leaked to a third party, who in turn uses it to do things they’re not supposed to.
If a company is breached, they will likely contact you and let you know what you need to do to secure your information. It’s annoying, but a modern fact of life and there’s relatively little you can do about it beyond using separate passwords for separate accounts and choosing to only do business with companies which prioritise online security.
Malware
Malware is any software intentionally designed to cause damage to a computer, server, client, or computer network. By contrast, software that causes unintentional harm due to some deficiency is typically described as a software bug.
Malware and viruses are a traditional online problem that still present a significant risk to people who use the internet. Most infections will be caught via infected files or malicious links, which is how they’ve always been transmitted. What has changed, however, is what these viruses do.
Many modern viruses are literally following the money – they instruct your computer to do things that will make them a profit. Just causing havoc isn’t really on the cards anymore. A perfect example of this is “cryptojacking” or “pharming”, which is where your device is turned into a zombie computer that mines cryptocurrency on someone else’s behalf.
Malware is pretty sneaky stuff, and you can pick it up in the most innocuous-looking of places. Viruses can come packed into innocent-looking apps from the app store, silly-looking pop-ups on websites, or even in fake games that your kids might accidentally download.
Preventing malware:
Without a doubt, the best way to protect your device from malware is to make sure there is an up-to-date security programme installed on your device. Secondly, ensure that the devices themselves are updated as older devices and operating systems are easier to infect.
On a more personal level, think and teach your family to think too. Never click on pop-ups and read app descriptions carefully to ensure that they seem legit and well-regarded. Just because something says it is a certain app, programme, or game doesn’t mean it is, so make sure you take contextual clues, like reading the description, reviews, URL, and download link to make sure you’re getting what you expect, even on official websites or stores.
Wi-Fi threats
Many employees access their work emails and work networks via public Wi-Fi hotspots, even though there is a risk that sensitive information such as login credentials could be intercepted by hackers. Many employees are unaware of the Wi-Fi security threats that lurk in their favorite coffee shop and fail to take precautions. Even employees who are aware of the Wi-Fi security threats often ignore the risks.
One of the most common ways of obtaining sensitive information is for a cybercriminal to set up an evil twin hotspot. This is a fake Wi-Fi access point that masquerades as the legitimate access point, such as one offered by a coffee shop or hotel. An SSID could be set up such as “Starbuck Guest Wi-Fi” or even just state the name of the establishment. Any information disclosed while connected to that hotspot can be intercepted.
Using a packet sniffer, a hacker can identify, intercept, and monitor web traffic over unsecured Wi-Fi networks and capture personal information such as login credentials to bank accounts and corporate email accounts. If credentials are obtained, a hacker can gain full control of an account.
Many people have file-sharing enabled on their devices. This feature is useful at home and in the workplace, but it can easily be abused by hackers. It gives them an easy way to connect to a device that is connected to a Wi-Fi hotspot. A hacker can abuse this feature to drop malware on a device when it connects to a hotspot.
Shoulder Surfing
Not all threats are hi-tec. One of the simplest methods of obtaining sensitive information is to observe someone’s online activities by looking over their shoulder. Information such as passwords may be masked so the information is not visible on a screen, but cybercriminals can look at keyboards and work out the passwords when they are typed.
When connecting to a home or work network, some form of anti-malware control is likely to have been installed, but those protections are often lacking on public Wi-Fi hotspots. Without the protection of AV software and a web filter, malware can be silently downloaded. At home
At home, there is a risk that someone might “hack” your Wi-Fi. In the best case scenario, they just want to get your fast internet for free but in the worst, they want to use your Wi-Fi to hack into your computer, phone, or home network. Luckily, the way to help prevent both is simple: good, strong passwords and up-to-date protection. The first will hopefully foil any attempts to gain access, and the second will detect the intruder if they do!
Phishing
Phishing is a type of social engineering where an attacker sends a fraudulent message designed to trick a human victim into revealing sensitive information to the attacker or to deploy malicious software on the victim's infrastructure like ransomware.
Phishing usually comes in the form of an email, SMS, or website pop-up from a company or person you trust. Once you engage, they’re likely to ask you to hand over personal details (information) or click on a link or download a file (malware).
Phishing prevention
The best way to prevent phishing is to think hard about incoming requests. Does this company usually email you? Do you even have an account with them? Is this the email address or phone number you gave this company to communicate with you?
Be highly suspicious of any email that asks you to do something, such as call them, log into your account, download a file, or click a link. Be extra suspicious of any urgency or drama in the communication – it’s trying to get you to act out of panic, without thinking.
If you do click a link or download a file, your security solution should spring into action and warn you of the dangers. Similarly, if someone does get access to an account or online service using your details, having multifactor authentication enabled (requiring two or more steps to access an account) will most likely stop them in their tracks.

When it comes to security problems relating to Wi-Fi, we can divide the category into two clear halves – the risks you face at home (piggybacking and hacking) and the risks you face using public Wi-Fi.
On public Wi-Fi
Out and about, you should avoid public Wi-Fi where possible. If you do connect, be aware that when using someone else’s Wi-Fi connection (sure, it’s called “Starbucks Free Wi-Fi”, but it could belong to anyone!), everything you do on that connection is funnelled through someone else’s computer – your bank details, emails, website logins, etc.
Prevent this by installing a mobile or traditional VPN, which creates a barrier between your activity and the provider of the Wi-Fi. If you haven’t got a VPN on a given occasion, you’re going to have to fire up your security suite, cross your fingers and, please, don’t even think of logging into your online banking!
Online security
Online security is all about staying alert on various fronts and acting proactively.
Sure, accidents and incidents will happen, but the same can be said for offline life and, as we can see, the distance between online and offline is closing every day.
In short, you need internet security software because hackers and cybercriminals have an evolving rota of tricks in their bag. Cyberthreats are dangerous, but they can be avoided in five short steps:
Use security software where possible.
Use a password manager to generate strong passwords.
Enable multifactor authentication (2-step authentication) where possible.
Don’t use public Wi-Fi.
Think and teach your loved ones to think!
A strong security suite can help protect your device. While being smart goes a long way, a security suite is an extra precaution for helping keep your precious information secure.
