How to protect yourself from cyber attack
A cyber attack such as the recent attack on the NHS and other IT infustructure brings security to the front of our minds, but how best can we protect our critical business and home computers from infection?
The recent NHS attack is a form of infection known as a "worm" containing "ransomware". It's purpose is to encrypt files rendering them inaccessable to the user then ultimately to blackmail that user into paying a ramsom to restore access.
Friday's attack spread to at least 99 countries affecting thousands of computer systems at banks, transportation companies. Although a patch to protect against attacks such as Friday's had been released by Microsoft, many computer systems hadn't been upgraded.
Ransomware has resulted in payments of millions of pounds in recent years as desperate users cough up the money to regain access to crucial files and data.
The Cyber Threat Alliance offers these guidelines to protect against ransomware
- Ensure that your operating systems, applications and firmware are updated with the latest versions of the software.
- Understand typical phishing techniques and how to thwart them, such as by not opening email from unknown email addresses or attachments of certain file types.
- Keep web browsers updated, and turn on settings to disable browser plugins, such as Java, Flash and Silverlight, preventing them from running automatically.
- Review access and security policies within corporate networks to limit access to critical infrastructure from systems and users who don't need it.
How do I keep my files safe from infection?
The best protection to keep your files safe is having a backup on a secure, encrypted location. Most importatnly, this means not keeping your backup on your own PC. If you keep your backup on your current computer or even an external hard drive that's connected then they will be just as vaunerable to attack as not having a backup at all.
