Patch management plays a critical role in minimizing business risk caused by outdated software in any IT infrastructure. But for many companies it can feel like a never-ending cycle that inspires fear and lack of action.

As a result, many organizations find themselves in a situation where their systems are outdated with the number of available patches to fix potential vulnerabilities and exploits becoming increasingly overwhelming.

But by following a few easy steps, you can take control of the process and make the most of the results. Whether you are looking to introduce patch management or already have a policy in place, here are some tips which will help develop a concrete strategy.

1. Know Your Software & Devices

The most important part of any patch management strategy is to know the devices and software that exist within the organization. Create an inventory of all machines, software, and any external systems or services that may access them, including mobile devices.

As part of your patch management procedure, keep this inventory up to date. It sounds simple, but if you don’t know what you have, you won’t know what to patch!

2. Identify & Prioritize

Patch management is overwhelming, but becomes more manageable once you accept that not everything needs patching every time. To understand the extent of your patch management scope, identify the patches that are available and list the updates that are absolutely necessary, prioritizing those that resolve major vulnerabilities.

Sometimes you may find that multiple patches are available as service packs or software updates, reducing the need to apply hundreds of patches individually. The key is to minimize the amount of patching you are required to undertake, without compromising the security of your organization.

3. Establish a Process & Maintain It

Many companies undertake patch management as an afterthought and go through the process only when they feel they require it, but patch management shouldn’t be an ad hoc activity. A successful patch management strategy is one that is ongoing.

Being realistic with the amount of IT resources available and setting it aside makes it much easier to maintain a regular schedule of patching. Keep it under control, because the longer you leave it, the more you’ll have to patch.

4. Test, Test Again, & Test Once More!

Patching can create more problems than it solves, making testing absolutely crucial to minimize any negative impact it can leave behind. Whenever a patch has been identified, run it on a test system before performing an organization-wide roll out.

Even without the resources and hardware to set up and maintain an elaborate test environment, you can do this by deploying the patch onto a system that is not business critical, either to members of the IT team, or selected members of the organization.

The results of the testing on hardware, software, and any other systems you may have, should be documented and approved by system owners. Remember, if testing doesn’t exist in your strategy, patch management becomes riskier than the risks you are trying to remove.

5. Change Management & Rollback

So it’s now time for rollout, but before doing so, ensure you have an effective change management process in place. Before patching, back up any critical systems, plan the steps of rollback, and perform a rollback dress rehearsal.

Disregarding change management and patching without proper rollback plans can be catastrophic, and recovering from the repercussions can be even more challenging and overwhelming than every pre-deployment stage!

With these steps in place, that never-ending cycle will be become a well-managed process, which when combined with a rigorous testing schedule, will generate the best return for the resources you have available.

Don’t let the sheer volume of available patches make you want to bury your head in the sand! Make sure your patch management processes put you ahead of the game.
