Patch management is the process by which organizations gain, test, and install multiple patches (sets of codes) in various operating systems and applications within the network to protect those systems and applications from potential threats and ensure business operations continuing. While waiting for the suppliers to give the most recent version, the patches apply to the running code to offer an extra layer of protection. The administrator of the information technology must be accountable for building a properly configured IT infrastructure and securing it against vulnerabilities.
Difference between patch vs update
Although terms such as “software update” and “patch” may appear to be interchangeable, there is in fact a significant distinction between the two. This distinction is that “update” meaning the provision of new features to those who have purchased a software license, whereas “patch” means correction of a bug. The latter sends codes to safeguard an organization’s IT infrastructure against potential security vulnerabilities. Patch management is a component of the internal IT teams’ efforts to maintain the efficiency of the firm and offer a secure IT environment.
It’s not advisable to install new upgrades on all the assets in your organization’s inventory as soon as they become available for first considering the repercussions. Instead, one should prepare their actions more thoroughly. The administration of patches must adhere to a comprehensive and well-structured method that prioritizes both cost savings and data security.
Important aspects of the patch management process in the ITIL framework include:
Create an up-to-date inventory of all of your production systems:
This is the only way to correctly monitor the assets in your ecosystem, regardless of whether the monitoring is performed weekly or quarterly. You will have a precise understanding of operating systems, version types, and IP addresses now in use, and also their geographical positions, and companies. This will arise from prudent asset management. The more often you keep your asset inventory, the more informed you will be, according to a general rule of thumb.
Roll out a plan for standardizing computer systems and operating systems to the same version:
Although it may be difficult to implement, standardizing your asset library will make patching faster and more efficient. You will standardize your assets and limit their quantity to a suitable level to speed up the remediation process when new patches are released. You and the technical teams will save time that would have been spent on remediation.
Establish a list of the existing security controls in place within your organization, including the following:
Maintain vigilant about the firewalls, antivirus software, and vulnerability management tool in your firm. You should know how they operate, what they are protecting, and the assets associated with them.
Examine the reported vulnerabilities and compare them to your inventory:
You will have a better idea of the security risk your organization faces if you utilize the vulnerability management tool at your disposal to identify which assets in your ecosystem are susceptible to certain vulnerabilities.
Determine the degree of risk:
Using solutions for vulnerability management, you can easily prioritize what needs to be corrected acceptably. So that, you can manage the firm’s assets that you deem essential. For mitigating the vulnerability of users, check out and then recommend the best VPN for Windows PC users.
Now, test, and then test again:
Apply the adjustments to a representative sample of assets within your lab environment. Check that the fixes won’t cause any difficulties concerning production environment by putting the machines through a battery of rigorous tests.
Applying new patches as it is tested and accepted:
After determining the sequence in which remediation actions should be accomplished, you may begin patching to effectively reduce potential risks and frauds in working environment. The most well-known and popular vulnerability managing tools have the power in automating patching process, hence eliminating the need for some manual effort. Consider deploying the adjustments to batches of assets; even if they were tested in a lab setting, they may have unanticipated implications when utilized in production. Before plunging in headfirst, ensure there won’t be widespread issues by testing the waters with a few fingers.
Then, watch out patch progression after that. It is time to verify the status of your assets following the successful application of the patch.
Different patch management types include:
IT administrators manually apply patches and updates on each workstation and piece of software as part of manual patch management. The option to deliver updates at any time, within or outside of business hours, is the most significant advantage of manual deployment. You have complete control over the patching environment while retaining individual access to servers, software, and devices.
Manual deployment is a time-consuming process that leaves the IT staff with little time to focus on other essential projects. This is among the disadvantages of manual deployment. In addition, manual deployment causes consumption of resources and increases the total operating expense of a corporation.
Automated Patch Management is a method for managing software patches in which operating system and application updates are distributed automatically via a centralized patch management server. The benefits of automated patches are:
- The timely distribution of security patches reduces the frequency of security breaches.
- Maximizes the efficiency of the workforce by reducing downtime.
- Reduces the IT team’s burden, allowing them to devote energy to more vital initiatives.
- This feature will handle the patching process, including asset management and documentation, also performance analysis, automatically as the organization grows.
How does your organization’s patch management program’s efficacy benefit your business?
There are several ways in which patch management may be advantageous to all tech businesses:
- A more secure environment comes as the primary benefit. By installing updates to vulnerabilities regularly, you contribute to the management and reduction of the risk existing in your environment. This helps to safeguard your company against any potential security breaches.
- If your company has products and/or services that require customers to employ your technology, you are fully aware of how important it is that the technology is working. Patch management in this sense, is a crucial aspect of maintaining the functionality of your systems, as it entails correcting software problems.
- It’s essential to avoid incurring excessive fines, as regulatory authorities may assess monetary penalties on your business if it fails to apply patches as necessary and, hence, does not meet compliance standards. The proper administration of patches ensures that compliance is maintained.
- You may improve your technology by installing patches, which will offer it more features and capabilities. This can provide your firm with a method for delivering software updates to a large number of users simultaneously.
