Patch management is an essential practice for businesses to maintain the security and stability of their IT infrastructure. Patches are released by software vendors to fix vulnerabilities and enhance performance, and failing to manage these patches can lead to security breaches and system failures. In this article, we will be discussing what are the best practices to follow regarding the patch management process to make sure your business’s security is flawless.
Why Is Patch Management Important?
As I said before, patching is important for a few reasons:
- Security: Patches are released to fix security vulnerabilities in software and systems. Failure to patch these vulnerabilities leaves the company’s systems exposed to potential security breaches, data theft, and other cyberattacks. Patch management helps to minimize these risks by ensuring that all software and systems are up-to-date with the latest security patches.
- Compliance: Many regulatory and industry standards require companies to implement patch management as part of their cybersecurity program. Failure to comply with these standards can result in hefty fines and legal consequences.
- Stability: Patches also provide bug fixes and other updates that improve the stability and performance of software and systems. Without patch management, companies risk facing system crashes, downtime, and other issues that can negatively impact their operations.
- Reputation: A company’s reputation can be severely damaged by a security breach or downtime caused by unpatched vulnerabilities. Customers may lose trust in the company and take their business elsewhere. Patch management helps to prevent such incidents and maintains a positive reputation for the company.
The Risks of Poor Patch Management
Improper patch management practices can expose an organization to a number of significant risks, including:
- Security breaches: If software vulnerabilities are left unpatched, cybercriminals can exploit them to gain unauthorized access to an organization’s systems and steal sensitive information or cause other forms of damage.
- Data loss or corruption: Malicious attacks can also result in data loss or corruption, which can have significant financial and reputational consequences for the affected organization.
- Non-compliance: Many industries and government regulations require organizations to maintain a certain level of security, and failure to patch vulnerabilities can result in non-compliance and potential legal action.
- Increased downtime: Patching systems can take time and require temporary shutdowns, which can cause significant downtime and disruptions to business operations.
- Damage to reputation: A breach resulting from an unpatched vulnerability can damage an organization’s reputation, leading to a loss of customer trust and potential revenue.
- Increased costs: Addressing security breaches, downtime, and other consequences of improper patch management can result in significant costs for an organization.
Overall, organizations that fail to maintain proper patch management practices can experience a range of negative consequences, making it essential to prioritize this aspect of cybersecurity.
Patch Management: Best Practices to Follow
1. Create an Asset Inventory
Before you start caring for vulnerabilities, you should start preparing. This step may seem self-explanatory, but it is often overseen. You should have a crystal-clear idea of what software and hardware your company is using, and know exactly how your environment currently stands.
Document your systems and understand which devices, operating systems, and third-party applications are currently being used in your organization.
Once you have a firm understanding of what you’re dealing with, it will be much easier for you to pay attention to vulnerabilities and discover available patches.
2. Determine Your Assets’ Risk Level and Assign Priorities
Not all assets are created equal. You need to investigate which ones of your systems are non-compliant, and vulnerable and thus need patches faster. It won’t help if correct identification and prioritization are not put in place. Patching the wrong system won’t take you too far.
Setting priorities and identifying goals for patching are crucial steps in the patch management process. It’s important to identify the software that has to be patched and establish a plan in order to avoid confusion and enable auditing procedures.
Also, make sure to prioritize the patches with high security risks, as they should be applied as soon as possible.
3. Establish a Top-Notch Patch Management Policy
A patch management policy outlines the standards and rules for handling vulnerabilities properly. This process includes several steps, such as testing, deploying, and documenting the security patches installed on the endpoints of your company. I have covered patch management policy previously, so I strongly suggest you read this article as well.
4. Test the Patches Before Deployment
Before deploying a patch, it is essential to test it in a controlled environment. Testing patches allows businesses to identify any issues that may arise from the patch, such as compatibility issues with other software. Testing should involve a representative sample of the IT infrastructure to ensure that the patch works correctly across all systems. By testing patches before deployment, businesses can avoid potential system failures or security breaches.
5. Analyse the Results Pre and Post-Patching
Keep track of the state and performance of your endpoints pre and post-applying patches. This practice is strongly related to the previous one, because sometimes, patches may actually slow down some processes. This way, if problems begin to occur, it will be easier for you to determine if they can be attributed or not to an applied patch.
Bonus tip: make sure you have a rollback plan, so that in case of errors or conflicts, you can restore your software to the previous working version as soon as possible. This should help you reduce downtime
6. Automate the Patching Process
Despite the fact that patching can be done manually, an automated procedure is always faster and more accurate. It will assist in reducing the possibility of human error and malware attacks.
By automating the patch management process, your system administrators will save time and be free to work on other security-related responsibilities. Also, you will have complete access to your IT system and be rigorous about monitoring fixes and vulnerabilities.
