NHS Ransomware Attack – Staying Safe

Last week, the world saw one of the most devastating cyber-attacks to date, infecting over 200,000 computers in nearly 150 countries, having a drastic impact on the operation of many businesses and NHS Trusts, including GP surgeries and hospitals. The fact that the ransomware was able to infiltrate enterprise level and government organisations has raised cyber-security concerns on an international scale, with many organisations using this as an opportunity to reassess their cyber-security protocols. So, with our current understanding of the attack, how can you stay safe?

Cyber Security Education

One of the most effective methods of protecting your business from a cyber-attack and reducing the chance of your business being targeted is by educating your staff on the most effective preventative measures. The majority of business vulnerabilities are caused by human error, and training your staff to be able to identify suspicious emails and the correct course of action to take when identified can often be your best line of defence.

 

Up-to-date Software Antivirus

It’s vital to ensure that your software is up-to-date and supported by the distributor. This is important as software is constanly being updated to remove vulnerabilities. This is made especially important as shortly before the WannaCry ransomware attack, Microsoft released an update for their currently supported operating systems, which removed the vulnerability that the worm used to gain access into many of the computers. Had the infected computers been using an up-to-date operating system with a secure anti-virus solution, the infection might not have been able to spread in the way that it did, and the damage would have been far less severe.

 

Preparation and Disaster Recovery

Whilst ensuring your business has taken the preventative measures necessary can drastically reduce the likelihood of your business becoming a target, you’re better safe than sorry. That’s why it’s important to ensure that all of your critical business data is backed up securely in at least one location off-site, as well as having an internal backup. This is the key to being able to recover from an IT failure or data loss as the result of a cyber-attack, and can be the deciding factor as to whether your business can recover.
