What is cyber security?

Cyber security means protection in the online space. Therefore, it can refer to the security settings you use on your online social and video gaming accounts or the software you use on your family’s devices.

Good cyber security means the risk of your family’s personal information falling into the wrong hands is less likely. As such, it’s important to implement security measures that protect your devices.

Explore this guide to learn about the different types of cyber attacks and the protections you can put in place to keep your family safe.

Types of cyber attacks

Poor cyber security leaves your devices at risk for attack, which can look like many things. It may therefore affect your devices and information security in different ways.

The following are a few cyber attacks your family could be vulnerable to.

This is closely related to cryptocurrency and results from clicking on suspicious links or online ads. When this happens, malware gains unauthorised access to your device and uses it to mine cryptocurrency. Mining cryptocurrency uses a lot of energy and power, so you will notice your device slowing down. However, it is otherwise undetected.

How to stay safe

Make sure all software your family uses is the latest version, install ad blockers where possible and talk to your child about the dangers of clicking on mysterious links or ads.

During the Covid-19 pandemic, MITM attacks became more frequent because of the use of virtual meeting software. When two parties communicate (i.e, the client and the host), an attacker might take over the session to steal information.

While many virtual meeting platforms increased security to stop these cyber attacks, using vulnerable WiFi connections leave users open to harm.

How to stay safe

Avoid connecting to public WiFi where possible or check that it is reliable and safe.

You might have heard of malware but do you know what it is? In short, malware (or malicious software) is a software designed to gain access to a computer system without permission. Once malware is on a computer, it can damage files or disrupt personal cyber security. A computer virus is a type of malware.

Someone might use malware to steal personal information, financial details or anything else that could benefit them but harm your family.

How to stay safe

Install software on your computer to fight malware. In addition to this, make sure your children understand how attackers might target them.

Password-sharing is common among children who don’t understand the importance of cyber security. In some cases, friends misuse each other’s accounts, which results in trouble for the account holder. However, password breaches can also happen in other ways.

When you register to new websites, there is always a risk of poor data security which result in data breaches. These breaches could result in passwords being released and used by third-parties. If you use the same password for every account, this creates more vulnerability. Unfortunately, many children use the same password across accounts.

How to stay safe

Use password managers to create secure passwords and check websites like Have I Been Pwned? to see if your data has been breached and where. Reset passwords on any accounts that have been compromised and delete discontinued accounts.

Phishing can lead to the installation of malware on your device or theft of sensitive information. It is often associated with emails from unrecognised senders but can also use established contacts. For example, they might use a contact’s first and last name but use a different email. Alternatively, your contact’s email could be hacked and used to phish.

How to stay safe

When you or your child receives an email, it’s important to think carefully about the content:

  • Is the sender’s email unfamiliar?
  • Or, if familiar, is the way the email is written strange?
  • Is the email unexpected (e.g., from a government body that doesn’t usually send emails)?
  • Is the sender asking you to click on random links?

Teach your child to delete such emails or ask you if they’re unsure. They should never click on links when they don’t know where they lead. This is true on social media, across different websites and through online video game chats as well.

A type of malware, ransomware blocks access to a computer system for financial gain. This is called ‘locker ransomware’ and disallows any use of the computer.

However, sometimes a computer is still usable but the files are encrypted and inaccessible. This is called ‘crypto ransomware’. Cyber criminals continue to block access until the owner pays a sum of money to release it.

How to stay safe

Ransomware can end up on your computer through phishing emails with infected attachments or through vulnerabilities in cyber security.

Additionally, clicking on mysterious links or going to untrustworthy websites can lead to infected devices. Teach your children to think before they click and ask you if they’re ever unsure.
