Cyber vulnerability: Log4j update and actions

Recently, a severe vulnerability has been identified in Log4j which is a piece of software widely used by applications and other services across the internet.

You may have heard about this in the news or read about it online.

What does it mean for you and your business?

The vulnerability means businesses can be exposed to cyber attacks so it’s important that your IT team or outsource service provider take action to identify if your systems are at risk. The National Cyber Security Centre (NCSC) has issued some advice and guidance on fixing the issue here.

It may not be immediately clear if the software, servers or systems that are used rely on the Log4j component, so it is vital to follow the guidance from the NCSC above.

In addition if you have a cyber policy, it is critical that you install the relevant updates and ‘patch’ your systems accordingly to ensure you continue to receive all the benefits of your policy.
