Patch administration—the method of planning and making use of updates throughout techniques—is among the most essential elements of stopping a safety breach. In actual fact, a Ponemon Institute report discovered that 60% of breach victims have been compromised as a result of lacking patches.
On this publish, we’ll check out the what, why, and the way of patch administration from an MSP’s perspective, together with what to not do and key MSP patch administration greatest practices.
What’s patch administration?
Basically, patch administration is all the pieces concerned with preserving your techniques up to date. That features figuring out what techniques want updates, deciding what updates to use, scheduling updates, working updates, and testing.
Patch administration applies to all of the property in an surroundings. PCs, servers, IoT gadgets, smartphones, community gear, software program purposes, and even drivers are all in scope. Widespread examples of patches embody working system (OS) updates, software upgrades, and firmware updates.
There are three foremost classes of “patches” you’ll be able to apply to a system:
- Safety patches: Handle safety flaws on a system.
- Bug fixes: Handle bugs from a earlier launch.
- Function updates: Add new options and performance to a system.
Notice that these classes aren’t essentially mutually unique. Typically a single replace will cowl all three classes without delay. For instance, a Home windows service pack (SP) is an replace that rolls up a wide range of fixes in a single launch.
Patch administration vs. vulnerability administration
You would possibly hear the phrases “patch administration” and “vulnerability administration” used interchangeably. Whereas comprehensible, that’s technically incorrect. Patch administration processes are particularly centered on updates. Vulnerability administration has a broader scope.
Vulnerability administration is the continual technique of discovering, prioritizing, and addressing safety vulnerabilities. In lots of circumstances, vulnerability administration and patch administration will overlap. For instance, as a part of your vulnerability administration processes, you might uncover a safety situation that you would be able to remediate by making use of a patch.
Advantages of fine patch administration
We’ve lined the what, however why ought to you’ve gotten an MSP patch administration course of? The three foremost advantages of patch administration are:
- Safety: Retaining your consumer’s techniques updated is among the single most impactful issues you are able to do to enhance their safety posture. Not patching makes it considerably simpler for risk actors to compromise these techniques. Case-in-point: the WannaCry and ExternalBlue had patches out there for over a yr and have been nonetheless being actively tried and exploited on a big scale within the wild.
- Compliance: In some circumstances, you want a patch administration course of to stay compliant with related requirements and rules. For instance, PCI DSS necessities name out the necessity to apply important or excessive safety patches inside a month (requirement 6.3.3 of PCI DSS 4.0).
- Productiveness: Upgrades can add new options and enhance software efficiency. Consequently, they’ll result in productiveness boosts that enhance enterprise workflows.
How NOT to deal with MSP patch administration
Generally the best approach to get began with a plan is to determine what to not do. To that finish, right here’s an MSP patch administration guidelines of issues to keep away from.
MSP patch administration greatest practices
With what to not do out of the way in which, we are able to bounce into our patch administration greatest practices for MSPs. There’s by no means a one-size-fits-all reply in IT, however these greatest practices can assist you jumpstart and optimize your patch administration workflows.
Set up and doc a patch administration coverage
It’s essential to be purposeful about patch administration. That begins with creating and documenting an MSP patch administration coverage. NIST 800-40 can assist with steering, however for smaller MSPs that may be so much to soak up. In the event you’re on the lookout for an easier place to start out, I like to recommend utilizing UC Berkeley’s Patching and Updates Tips as a reference.
TIP! Have a plan for finish of life {hardware} and software program. In lots of circumstances, there’s no patch for a susceptible system or software. Ensure that your coverage addresses this state of affairs.
From an operations standpoint, you need to use instruments that robotically implement your patch insurance policies. For instance, Syncro lets you assign particular replace insurance policies for various IT property. By codifying granular insurance policies within the instruments you utilize to keep up your techniques you’ll be able to keep away from documentation drift and guarantee they’re enforced in manufacturing.
Take into consideration patching throughout procurement
The software program and {hardware} you purchase as we speak is what you’ll should patch tomorrow. In the event you’re liable for procuring IT property in your shoppers, contemplate patch administration through the shopping for course of. Key inquiries to reply embody:
- Does the seller launch patches for his or her merchandise? How typically?
- Is there a simple approach to apply updates as soon as they’re launched?
- Do updates require the product to reboot or be taken offline?
- How will you be notified of updates?
- Does the seller disclose vulnerabilities publicly?
Centralize asset administration
Centralizing IT property in a single system makes it simpler to grasp and report on improve standing, implement patch insurance policies, and enhance general infrastructure visibility. For MSPs, RMM software program is usually the appropriate resolution. Along with centralizing property from a number of shoppers and websites in a single system, an RMM can assist you deploy patches and outline safety insurance policies.
Observe patch statuses
It’s one factor to schedule patches, it’s one other to know if patches have been utilized efficiently and what nonetheless must be performed. As an MSP, you need to guarantee you’ll be able to simply and reliably decide the patch standing of your consumer’s techniques.
Prioritize patches by severity
Simply because one thing may be performed now doesn’t imply it needs to be performed now, and even in any respect. For instance, most often, it is sensible to use a important safety hotfix as quickly as sensible. However it doesn’t make sense to drive a noon replace that reboots your consumer’s PC to push a patch for a minor situation. Use CVSS scores and enterprise context to make an knowledgeable resolution about when and the way to apply patches.
Syncro can assist simplify your MSP patch administration
With out the appropriate instruments, managing patches throughout totally different clients and websites can change into time-consuming and inefficient. Syncro is all-in-one cloud-based MSP software program that helps you scale and automate patch administration.
With Syncro’s RMM agent put in on buyer PCs, you’ll be able to:
- Run stories to quantify what property are lacking patches
