System patches might not always take centre stage in cybersecurity discussions, but they play a crucial role in maintaining the integrity of your digital infrastructure. In our interconnected world, understanding the different types of patches and their influence on system security is essential knowledge for business leaders and IT professionals alike.
This blog will demystify patches so you can implement a patching strategy that fortifies your systems against the evolving threats of the digital landscape.
Before we dissect the different categories of patches, it’s vital to understand the overarching importance of patch management.
First, a simple question: “What are patches?”
Patches are updates software vendors release to fix identified bugs and vulnerabilities or improve their products’ functionality. Neglecting to apply these updates can leave your systems open to exploitation by malicious actors.
Starting with the most critical type, security patches are issued in response to vulnerabilities that have been discovered. These patches are not optional; they are necessary to prevent potential breaches. Cyber threats evolve continuously, and new vulnerabilities are a constant security concern. Without timely application of security patches, businesses face the risk of data breaches, systems hijacking, and many other dangers.
Feature patches are about more than just security. They introduce new features or enhancements to the software, potentially improving user experience and operational efficiency. However, they also come with their own set of risks. A balance must be struck between the desire for additional features and the need to maintain a secure system. Knowing what feature patches to install and which to ignore is best left to trusted IT professionals.
Compatibility patches ensure your system’s software functions smoothly with existing and updated operating environments. Incompatibility can lead to performance issues or system failures, directly impacting your business operations and possibly affecting your security posture.
In isolation, each patch mitigates specific risks within the software for which it is designed. Together, the patches create part of a holistic defence strategy that protects the software in question and the entire ecosystem. Neglecting one type of patch affects the whole system’s integrity, potentially leading to so-called ‘chain reactions’ of vulnerabilities.
In a Forbes article titled, The Imperative of Patching: A Resolution for Cybersecurity in 2024, author Emil Sayegh said, “Recent cybersecurity events, highlighted by a major breach at ICBC bank, have cast a glaring spotlight on the importance of patching as a vital component of cybersecurity.” Sayegh notes, “In an era where digital threats are constantly evolving, patching is not a choice but a necessity.”
Given that patch management is complex and multifaceted, it’s crucial to establish structured processes to handle patches effectively. Proactive patch management is not a one-time event but an ongoing practice requiring strategy, oversight, and adaptability.
A systematic approach to patch management involves identifying the patches relevant to your systems and establishing protocols for prompt deployment. This should include prioritising security patches while considering the impact of feature and compatibility updates.
Automated patch management tools can significantly streamline the process, ensuring that critical updates are not missed. However, manual oversight should always complement these tools, particularly when assessing the potential impact of updates on system performance or compatibility.
Effective patch management also requires continuous monitoring of vendor communications for patch releases. Once patches are identified and deployed, systems should be thoroughly tested to ensure the updates do not introduce new issues or conflicts.
Whether you manage patching in-house or outsource it to a Managed Service Provider (MSP) ultimately depends on your organisation’s needs and capabilities. While managing patching internally may seem cost-effective, it requires significant resources and dedicated staff to stay on top of updates and potential vulnerabilities. Outsourcing to an MSP can alleviate this burden while providing the cybersecurity expertise needed to leverage Patch Management within the scope of a comprehensive cybersecurity strategy.
Awareness and diligence in patch management are integral components of a comprehensive cybersecurity strategy. By understanding the different types of patches and their collective impact on systems security, you can make informed decisions that safeguard your business against cyber threats. Stay abreast of the latest patch releases and prioritise a proactive approach to system maintenance. Remember, in cybersecurity, the strength of your defences is only as good as your weakest link – and an unpatched system is a weak link.
