The National Cyber Security Centre (NCSC) recently published some guidance for businesses on keeping safe from ransomware. We are translating them into plain English and giving practical advice on staying safe online. We are experts in Hull IT security and can help your business to stay safe online.
How does ransomware infect your system?
Computers become infected with ransomware in a number of ways. Often, users get tricked into running programs that appear legitimate, but which actually contain ransomware. These can arrive in emails, through authentic-looking attachments or links to websites that resemble real ones (also known as phishing). Recent ransomware infections have relied on vulnerabilities in Windows or other software. If this is the case, then simply visiting a malicious website may be enough. File transfers between computers (using external drives or USB memory sticks) can also cause malware to spread.
Preventing ransomware with enterprise security
Ransomware is one of the many different types of malicous software. You can minimise the risk of your business computers being infected by ransomware by using the same precautions as malware in general.
Vulnerability management and patching
A lot of ransomware exploits software vulnerabilities in your operating system, web browser, plug-ins and other applications. When such loopholes are discovered, software providers make patches available to close them. Keeping software updated is the most effective way to stop your system being compromised.

Controlling code execution
Only your administrator should be able to install software on business PCS, and you should only be logged in as the administrator if that is your intention. All other business activity should be conducted through “normal” user accounts. Your Hull IT Support company will be able to check this for you.
Block certain internet traffic
It is recommended to using a security service to proxy outgoing internet traffic. You can filter out attempted connections based on categories or the reputation of the sites your users attempt to visit. If staff attempt to access a malicious site it can be blocked as “not for business use” and keep your files safe.
