Running out ‘a’ time: Importance of Regular Updates in IT Security

When it comes to IT security, it’s not only crucial to have protective systems in place, but it’s equally important to ensure that updates are applied. Regular updates do more than just reduce the risk of vulnerabilities; they also ensure that fixes and improvements are applied to the product, enhancing overall performance and security.

The Hidden Risks of Neglecting Updates

In many cases, IT security products are left running in the background with minimal interaction. This hands-off approach can seem sufficient at first glance, but the reality is that the risk of vulnerabilities increases over time. Many organisations focus diligently on updates such as antivirus (AV) signature files and endpoint protections but often overlook the backend infrastructure. This “if it ain’t broke, don’t fix it” mentality can lead to significant security gaps.

For instance, consider a firewall that hasn’t been updated for years. While it may still function as intended, it could be missing critical security patches that address newly discovered vulnerabilities. Cyber attackers are constantly evolving their techniques, and outdated systems are prime targets for exploitation.

The Resource Challenge

During my time as a technical consultant, I have encountered numerous cases where resource limitations are a key factor in keeping products up to date. IT departments are often stretched thin, and routine maintenance can fall by the wayside. However, neglecting these updates can lead to dire consequences.

One of the biggest concerns is running out of time, especially when a product’s end-of-life (EOL) is approaching. Once a product reaches EOL, vendors typically stop providing updates and support, leaving the system increasingly vulnerable to attacks. Organisations need to plan ahead and allocate resources to ensure that all systems are current and secure.

The Consequences of Falling Behind

Failing to apply regular updates can lead to several negative outcomes:

  1. Increased Vulnerabilities: Outdated systems are more susceptible to new threats.
  2. Compliance Issues: Many industries have regulatory requirements that mandate regular updates and patches.
  3. Operational Inefficiencies: New updates often include performance improvements that can enhance system efficiency.
  4. Higher Costs: Emergency updates and fixes can be more costly than routine maintenance.

Don’t rely on hindsight to wise up to the risks. Keep your updates regular.
