Potential computer security threats you need to know about

Cyber-attacks have become more commonplace in recent years, and how hackers and cyber criminals find ways to access computer systems is also evolving. There are always new scams appearing and it seems that no sooner is one problem patched, another vulnerability is identified. To keep your computer secure, you need to understand the risks.

When it comes to cyber-attacks, there are many different types, and here are just a few of them for you to look at.

• Denial-of-service (DOS) – this type of attack causes a computer system to become overwhelmed as they flood the system with information. This means that the computer system can not perform its usual functions and prevents everyday tasks from being carried out.
