We'll help you with steps to keep your IT systems and data safe and sound, giving you clear instructions and useful tips. We'll also show you what you need to meet the CMMC 2.0 standards.
Keeping your IT systems and data secure and reliable is a big part of CMMC compliance. It's important to protect Controlled Unclassified Information (CUI) to keep your business operations safe. This guide will walk you through critical practices, including CMMC flaw remediation, malicious code protection, vulnerability scanning, implementing periodic system scans, and more. We’ll also cover proactive security measures like Endpoint Detection Response (EDR) CMMC and how to maintain a robust System Security Plan (SSP).
We know it can be difficult to ensure your systems and information stay intact, but it's crucial for your security. For expert guidance on CMMC requirements, book a free consultation with our certified practitioners today.
“Identify, report, and correct information and information system flaws in a timely manner.”
Level Of Effort: Medium
When you spot weaknesses using RA.L2-3.11.2 – VULNERABILITY SCAN, having a way to test patches and updates before using them is key.
Each company might do this differently, but usually, they try patches with a small group first to check for any problems. After that, if everything looks good, they use them company-wide. It's a good idea to discuss this process with your IT team to decide what works best for your company.
“Provide protection from malicious code at appropriate locations within organizational information systems.”
Level Of Effort: Low
Companies must keep their information systems safe from harmful software like viruses, spyware, and ransomware. The goal is to find these weak points and use tools like antivirus programs and firewalls to stop or reduce the damage from malicious code.
What our clients say
“Update malicious code protection mechanisms when new releases are available.”
Level Of Effort: None
This should be addressed if you implement all of the recommendations under SI.L1-3.14.2 – MALICIOUS CODE PROTECTION, especially the auto-update feature.
“Perform periodic scans of the information system and real-time scans of files from external sources as files are downloaded, opened, or executed.”
Level Of Effort: Low
This rule highlights the need to scan the whole system often and also scan files that come from outside right away. This is to find and deal with threats like harmful code. By always checking for dangerous files that might get into the system, businesses can get better at protecting themselves against online threats.
Optimize Antivirus Solution: Work with your IT team to make your antivirus better. We suggest you do these things:
Revise System Security Plan (SSP): It's important to update your System Security Plan (SSP) to include details about who or which team checks the antivirus scan reports. Also, explain the steps you'll take if you find security issues during the scans.
“Monitor system security alerts and advisories and take action in response.”
Level Of Effort: Low
This section requires businesses to pay attention to security alerts and updates. They need to do this to keep their online safety strong. By knowing about new threats and problems from sources they can trust, businesses can act fast to keep their computer systems safe.
“Monitor organizational systems, including inbound and outbound communications traffic, to detect attacks and indicators of potential attacks.”
Level Of Effort: Medium
This rule means that businesses must watch their systems to catch any signs of trouble, both from outside and inside. It's important to pay attention to anything that might suggest an attack. You need to keep an eye on what's happening on the outside (like people trying to break in) and the inside (like employees doing things they shouldn't).
This is especially important if you follow all the suggestions in our Audit and Accountability (AU) article.
What our clients say
“Identify unauthorized use of the information system.”
Level Of Effort: Low
This should be addressed if you implement all of the recommendations in the Audit and Accountability (AU) section.
