A cyber attack

 

A cyber attack can be expensive. Last month, Gloucester council paid £380,000 to help restore their systems after a cyber attack

Getting systems up to normal after an attack can be costly and time consuming. A way to avoid this is to prevent malware and cyber attacks before they take place.

Making protection difficult is that there are many different types of malware, our guide covers the most common ones.

 

Types of Malware

Trojan

This is a program pretending to be a legitimate one, which relies on the user in order to infect the device. To help protect against Trojan software do not click any links from unknown sources.

Ransomware

It Infects the computer and holds the data to ransom, using money as a leverage. If the money is not paid the data is deleted. However there is no guarantee of getting the data back if the Ransom is paid. To protect against this don’t click on malicious links and make sure the data is backed up.

Spyware

It logs keystrokes in order to gain entry to passwords and usernames. Through doing this the spyware may have access to information and or money. To prevent this make sure your antivirus is up to date and anti tracking extensions will help to avoid being detected on browser

Adware

Issues with devices

As more people are working from home, with laptops and even their mobile phones, it can make it harder to secure the devices. Mobile phones are particularly hard to secure, which often leaves them vulnerable.

 

Cloud based problems

Cloud based software has become increasingly popular as you are able to access it from anywhere and have an easy way to back up your files. However, if the cloud application is not managed properly it leaves the system vulnerable.
