The cybersecurity maturity model certification (CMMC) is a path toward preemptive security, in which enterprises change their attention from responding to security incidents to avoiding them in the first instance.
Most firms will wish to strive for the fourth or higher level while prepping for their CMMC evaluation, as this is the minimal need for managing CUI.
Level 3 CMMC security includes log collecting and analysis, which are critical initial steps toward proactive protection. For instance, practice AU.3.048 mandates that enterprises acquire all audit records and store them in a centrally controlled repository, whereas AU.3.051 mandates that audit log evaluation, assessment, and notification procedures be coordinated. Here, CMMC consulting Virginia Beach firm can help firms implement SIEM.
Understanding Security Incident and Event Management (SIEM)
While CMMC is explicit about which policies you must have in place to achieve a higher safety maturity tier, you have complete flexibility over how you execute them and which technologies and resources you utilize.
The mentioned CMMC security procedures, on the other hand, adequately characterize what SIEM is. Because maintaining audit logs across numerous separate systems renders it nearly challenging to link events from different systems, the crucial factor here is the aggregate administration of documents.
SIEM technologies, which are usually contracted, cloud-hosted systems, are critical components of any contemporary cybersecurity approach. Newer systems rely heavily on AI and ML to gather and analyze data to the degree that would be nearly impossible for humans to achieve alone.
Threat recognition, assessment, and alerting are the three main capabilities of SIEM. Additional functionality like analytics and incident handling, as well as log gathering, are critical.
Installing a SIEM platform is critical to passing your CMMC exam and improving your security posture for the following reasons:
#1. Data aggregation
Data gathering and consolidation are the first steps in the SIEM process. A SIEM gathers audit log data from all of the systems that are linked to it. Networked devices, desktops, routers, DNS servers, and other items fall under this category.
Any equipment that processes potentially confidential material, whether software or hardware-based, may and should be linked to the SIEM. As a result, the SIEM will be able to capture all vulnerability information from throughout your network and store it in a centrally controlled repository in accordance with CMMC standard AU.3.048. CMMC consultant suggests DoD contractors to emphasize on SIEM.
#2. Normalization of data
The next step in the SIEM process is to normalize the data acquired in order to provide a consistent perspective of your security activities, as required by CMMC standard AU.3.051. This gives the system total visibility into your network activities, allowing it to detect irregularities rapidly.
Because the vast volume of log files makes manual examination unfeasible, SIEM utilizes event normalization to establish a baseline for regular network activity. If something odd occurs, the incident will be reported to the SIEM process’s next level. In addition, the SIEM successfully converts logs into a standardized and human-readable format, providing you with a comprehensive picture of what’s going on in your network.
#3. Data analysis
A rudimentary SIEM solution may provide only alerts. On the other hand, more advanced systems use machine learning and artificial intelligence to analyze log data at scale. Anomaly occurrences may then be addressed right away and submitted to a security professional for manual evaluation if necessary. Moreover, an AI-powered platform builds complete danger profiles by continually learning from prior occurrences.
A comprehensive, enterprise-grade SIEM solution’s data collection and analysis are critical in preemptive vulnerability identification. This makes it easier to combat more complex assaults like advanced persistent threats (APTs), allowing you to reach higher CMMC security levels.…
While the measures implemented in CMMC levels 1 and 2 provide the bare minimum of protection, the third tier is where things start to get interesting. That’s also the grade that most businesses should strive for, not only because it establishes the minimal security criteria that an organization must meet to handle regulated unclassified data lawfully. Seeking help from professionals offering IT services for government contractors can be beneficial for small business DoD contractors.
Companies that currently have agreements with the US Department of Defense should focus on CMMC level 3. The DFARS 252.204-7012 provision, a transitory resolution centered on the NIST SP 800-171 architecture, currently applies to these businesses. CMMC level 3 does, however, include several new controls that NIST does not address.
What does it mean to have excellent cyber hygiene?
Organizations must satisfy a minimal degree of cyber security before embarking on high-value agreements with the Department of Defense. It also acts as a stepping stone to higher stages, which will be required after CMMC is wholly deployed in October 2025. Level 3 covers all NIST SP 800-171 rev. 1 controls in detail, as well as 13 extra security practises from other sources.
Achieving CMMC level 3 requirements is a lofty aim, but one that may pay off handsomely for any would-be defense contractor or subcontractor. Nevertheless, you won’t be able to apply all CMMC security policies from this level in a matter of weeks or months. After all, it has 130 controls in total, including 58 new ones and all of the regulations from the two preceding levels.
A few of the new practices proposed in CMMC level 3 are as follows:
Accountability and auditing (AU)
Organizations must first create extensive monitoring and reporting systems before improving their security protocols to the extent of being proactive. Level 2 of the CMMC introduces auditing and accountability, whereas level 3 adds seven new controls that oversee more sophisticated auditing processes. When an inspection or recording procedure fails, for instance, compliance now necessitates the implementation of automatic warnings. It also necessitates collecting all audit data into centralized repositories for in-depth study and assessment. The information gathered throughout these auditing procedures your IT solutions and services company will aid in the development of a cycle of continuous security routine improvement, creating a core aspect of CMMC level 4.
Asset administration (AM)
Within CMMC regulation level 3, asset administration is one of 2 additional domains. This level contains only one regulation to establish particular practices and processes for dealing with CUI. This is a core domain feature that eventually includes the capacity to identify, categorize, catalog, and analyze all equipment/software assets and their many constraints implicated in the data transferring of CUI. Establishing a solid asset monitoring regimen for securing sensitive data at scale is critical.
Situational awareness (SA)
Situational awareness is the second of the two new domains established in CMMC level 3. It draws on the strongly linked attention and education domain that was established in CMMC level 2. To acquire a level 3 certification, just one control is required: collecting, analyzing, and sharing all applicable cyberthreat information with participants. Because it incorporates information utilized by security specialists to hunt for risks proactively, this is significantly more technical than regular security awareness training. Internal sources, such as log data and alternative entities, such as renowned cybersecurity blogs and forums, can provide cyber threat intelligence.…
