Using old software that is no longer supported can pose serious security risks to your organisation.
The cyber security landscape is constantly evolving and it is very common for vulnerabilities to be discovered in software over time. Software developers respond by creating patches and fixes that they release to maintain the security of the software. However, when software is no longer supported these fixes are not developed and released and the known vulnerabilities become easily exploitable.
Running outdated software may make your organisation more vulnerable to viruses, malware and ransomware attacks and compromise the integrity of your data. Even if the software in question holds no data or limited information, the outdated software vulnerabilities may provide a route for an attacker to gain access to the remainder of your systems and data. A data security breach may cost your business time and money as well as damaging your reputation.
Unsupported software not only leaves your organisation open to security risks but may cause other business disruptions as software and hardware may stop working or be incompatible with newer systems and there will be no support route to resolve these issues.
Upgrading to the new supported software should be a priority for your organisation but occasionally it may not be possible to upgrade to the new supported software straight away and it is important that in these instances extra precautions are taken to reduce the likelihood of an attack. This could be by preventing the devices from accessing external untrusted content and services and preventing access to sensitive data or services from the vulnerable devices.
Software updates often happen automatically on supported software but it is still best practice to manually check for updates to ensure your organisation is fully protected.
