Patch Management: Definitions, Lifecycle, and Management

In the burgeoning IT landscape, patch and vulnerability management becomes imperative for improving overall organisational efficiency. With the aid of a robust patch and vulnerability lifecycle management, organisations can effectively address vulnerabilities in their systems and fortify defence against cyber threats. Effective implementation ensures optimised organisational performance, streamlining operations and boosting overall efficiency. Conversely, failure to employ effectively can expose businesses to a panoply of pernicious threats, each carrying the potential for operational disruptions and reputational damage. Organisations must devote considerable time to developing a robust policy. By embracing a proactive approach to patch and vulnerability management, organisations can lay concrete and future-proof IT foundation.

Patch and vulnerability management emerges as a critical cyber security bulwark for identifying and eliminating IT bugs, fostering productivity, and mitigating security vulnerabilities. Software vendors build and distribute patches to identify shortcomings and vulnerabilities in their software systems. These issues range from nascent bugs to more sophisticated technical anomalies. Threat actors often exploit these vulnerabilities, posing a greater security risk. Consequently,it can become crucial to building robust protection against these vulnerabilities and reducing susceptibility to cyber threats.

What is Patch and Vulnerability Management?

Patch and vulnerability management is the sophisticated process of applying updates to a website’s software, drivers, and firmware against vulnerabilities. The primary objective of patch and vulnerability management is to fortify the system’s defence mechanism that threat actors deploy for malicious purposes. Organisations can constantly employ patch and vulnerability management to safeguard their data against multiple vulnerabilities and improve efficiency.

Effective patch and vulnerability management ensures the best system performance, boosting productivity. Avoiding patch and vulnerability management can be risky, exposing your business to vulnerabilities and security risks.

Why is it Important?

The primary goal of patch and vulnerability management is to protect your system from vulnerabilities. Patch and vulnerability management also brings several other benefits which include:

Improve Productivity within the Organisation

Contrary to many misconceptions, patch and vulnerability management does not necessarily entail a trade-off with productivity. Software fortified with the latest patches works best and improves employee productivity. The optimised software allows employees to manage their tasks better, augmenting working efficiency and allowing them to focus on the core tasks without technical glitches and system interruptions.

Cost Optimisation in Device Lifestyle Management

In the contemporary landscape where remote work and decentralised operations are prevalent, patch and vulnerability management becomes pivotal to supporting a highly dispersed workforce. Its function extends beyond managing updates. Leveraging IT tools empowers IT teams to seamlessly manage software updates across different endpoints, restricting the need for expensive hardware shipments and enhancing cost efficiency.

Critical Steps

Establish a Standardised Inventory of  Hardware & Software

Establishing a robust inventory of standardised hardware and software is the first step in the patch and vulnerability management process. It requires a meticulous approach involving documentation of various components across hardware and software domains. The document must encompass all the exclusive items, including every operating system and application your organisation uses. Moreover, these initiation steps represent the beginning of the patch and vulnerability management journey. Hardware vendors, comprising entities selling network hardware, intermittently disseminate firmware upgrades to rectify problems on the hardware level. This process is similar to software makers releasing patch updates to address the vulnerabilities. Hence, it’s critical to incorporate the firmware into the inventory and address security flaws.

Collect Details on Hardware and Software Vulnerabilities

The second critical point arises in keeping track of available and highly recommended patches. While managing the fundamental building blocks of Microsoft Office, Windows, Linux, Unix, and analogous programs is straightforward, updating third-party software demands a manual examination of the vendor’s platform. Hence, operators must scrutinise the patches to ensure they address security vulnerabilities. The process becomes more complex due to the varying nature of some of these programs. The majority of systems and applications are designated to mitigate security vulnerabilities.

Identify the Vulnerabilities

Identifying the vulnerabilities within a vast array of inventory and filtering changes to endpoints is one of the trickiest parts of patching. While numerous businesses comprise lists of potential software, integration of these lists into assets to identify the requirement for a given patch presents logistical hurdles and labour-intensive endeavours. However, the filtering process will significantly speed up patching by determining the patch requirements and matching them with the specific systems.

Utilise a Test or Pre-Production Environment

Using a test or pre-production environment is vital in the patch and vulnerability management process because each patch can introduce vulnerabilities. Therefore, it’s essential to conduct a thorough evaluation before deploying it in your production environment. While software vendors do some testing, they might not address issues thoroughly due to time constraints. Consequently, there have been instances where flawed updates from vendors have disrupted stable environments.

Test the Stability of the Patch

Your team must assess the patches’ stability to prevent crashes during lab testing. This evaluation should follow a robust protocol outlining the patch test duration in your organization’s lab. Every patch must undergo rigorous testing, but companies must also balance this with the necessity and urgency of addressing security flaws.

Patch and Vulnerability Management Review

Implementing a formal review procedure is crucial. Patching and vulnerability management should be informed about which patch to apply, the testing results, and the list of endpoints scheduled to receive the patch. With this information, they can authorise the patch distribution process.

Conduct A Trial Deployment of Patches

A trial deployment process is crucial to verify a patch’s suitability for production use. This preliminary phase adds an extra layer of assurance, helping companies identify issues that might have been overlooked during lab testing. By selectively applying the patch, potential problems are contained, minimizing their overall impact.

Document Sytems Pre and Post Patching

Documenting systems is the final step in the patch and vulnerability management process. It is crucial to meticulously record the system’s conditions before and after the patch update. This thorough documentation helps in identifying any issues that may arise following the patch implementation.

Conclusion

As the cyber security landscape escalates, organisations must employ a robust patch and vulnerability management strategy to address emerging threats. In addition to fortifying security, patch and vulnerability management keeps your applications on pace with market trends. Ultimately, it’s about closing security gaps and building a robust defence mechanism to counter evolving cyber threats effectively.
