Government Contractors must prepare for Cybersecurity Maturity Model Certification

In 2017 defense contractors became subject to a cybersecurity mandate by the Federal Government, starting with the Defense Acquisition Federal Regulation Supplement.  DFARS required DoD Contractors to adopt cybersecurity standards according to the NIST SP 800-171 Cybersecurity Framework.

On January 30, 2020, the Department of Defense  released version 1.0 of the Cybersecurity Maturity Model Certification (CMMC) to ensure cybersecurity controls and processes would be put in place to protect controlled unclassified information (CUI) on DoD contractor systems.

CMMC will be mandatory for 300K Government Contractors, establishing cybersecurity as a foundation for future DoD Acquisitions.   This imposes cybersecurity requirements on a large base of contractors that has never dealt with Federal Contractor Information (FCI) requirements.

CMMC requirements will flow down to all subcontractors from prime contractors.  All future RFPs will require adherence to various levels of CMMC.  Government Contractors will have to pass a CMMC audit so they can become certified and continue to offer their products and services to the DoD.  The required CMMC level will be a pass/fail evaluation at the proposal stage for contract awards.  Contracts will not be awarded to organizations that do not meet the required level.

Between June and September of 2020, the initial round of audits will begin for a select number of Department of Defense Programs/RFIs, with the required CMMC Levels identified. A CMMC 3rd Party Assessment Organization (C3PAO) will ask Defense Contractors to prove how they process, store and transmit Controlled Unclassified Information (CUI).  Government Contractors will need to be certified to the required Level in order to receive and bid on the RFP.

The timing of Accreditation Audits is now projected to be Q4 2020 (Calendar) going forward, with RFI’s including CMMC references as early as June and RFPs including CMMC references by Q4.

CMMC requires policy, process and plan documentation covering all security domains

The CMMC Model has 5 Levels with a number of defined Practices and Processes in each Level

NIST Controls
Level 1 17 Basic Cyber Hygiene Basic safeguarding of FCI
Level 2 65 Intermediate Cyber Hygiene Transition step to protect CUI
Level 3 119 Good Cyber Hygiene Protecting CUI
Level 4 123 Proactive Protecting CUI and reducing risk of APTs
Level 5 128 Advanced/Progressive Protecting CUI and reducing risk of APTs

 

Government Contractors can use the “Self Assessment Handbook – NIST Handbook 162” provided by the National Institute of Standards and Technology (NIST).

CMMC Level 3 is based on compliance with NIST 800-171, plus 20 additional Practices, including the following:

Access Control:

  • Limiting information system access to authorized users
  • Separating the duties of individuals to reduce the risk of malevolent activity
  • Prevent non-privileged users from executing privileged functions and capture the execution of such functions in audit logs
  • Prevent unauthorized access using authentication and encryption

Audit and Accountability

  • Create and retain system audit logs and records to enable monitoring, analysis, investigation and reporting of unauthorized system activity
  • Review and update logged events
  • Alert in the event of an audit logging process failure
  • Collect audit information (logs) into one or more central repositories
  • Protect audit information and audit logging tools from unauthorized access, modification and deletion
  • Correlate audit record review, analysis and reporting processes for investigation and response to indications of unlawful, unauthorized, suspicious or unusual activity
  • Provide audit record reduction and report generation to support on-demand analysis and reporting

Media Protection

  • Implement cryptographic mechanisms to protect the confidentiality of CUI stored on digital media during transport
  • Save security event log data in one or more central repositories

Recovery

  • Regularly perform complete, comprehensive and resilient data backups

Security Assessment

  • Monitor security controls on an ongoing basis to ensure the continued effectiveness of the controls

Level 3 of the CMMC model specifically points to the requirement for Security Event Log Management Software.

Prophecy International has been providing Event Log Management Solutions to the Intelligence Community, Military, Non-Military and Government Contractors for over 15 years, and continues to invest in software that supports event log collection, forwarding, analysis and reporting.   SNARE Enterprise Agents and Log Management Servers will help government contractors address CMMC Level 3 Requirements.

Using Snare to Detect a Threat

Cyber Security news is inundated with new ransomware attacks using current events to entice end users to open and click on an email that will encrypt data and demand ransom.  Some however are far more invasive, such as the RYUK Ransomware, which is the final act in an attack, one that starts with the Emotet malware, followed by a deployment of Trickbot, and then the ransomware.  The first parts of this attack allows the cyber criminals to determine, based on your data, what ransom should be set. It is also interesting to note the Emotet and Trickbot were primarily used to exfiltrate data, but as corporations struggle to recover from the ransomware, this may go unheeded until the information is available through nefarious channels, and of course then an organization becomes a headline.

While not by definition an Advanced Persistent Threat, which is defined as “a prolonged and targeted cyberattack in which an intruder gains access to a network and remains undetected for an extended period of time. The intention of an APT attack is usually to monitor network activity and steal data rather than to cause damage to the network or organization.“  Both of these types of attacks are stealthy, and can avoid detection, unless using a system that that monitors and analyzes the activity on individual systems.

Snare Agents are designed to send event log data in real time and can be configured to monitor specific Windows Registry keys and system folders that are common malware load points.  In each of the various versions of windows, there are specific locations within the file systems and registry that are used to load applications and related files.  While these are used by legitimate programs, they are also commonly used as attached vectors for malware. Malware needs to be installed persistently, so that it remains active in the event of reboot, and most persistent techniques on the windows platform involve the use of the Windows Registry.

Certain registry keys may contain values used to load applications, and in this instance malware, when Windows is started.  This is extremely difficult to mitigate this with traditional preventative tools, however using the Snare Agent to monitor the registry can assist in the detection of this threat.

There are specific run keys that are created by default with the Windows Systems:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

In addition, other Registry keys can be used for persistence:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ Explorer\User Shell Folders

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ Explorer\Shell Folders

With the Snare Agent it is incredibly easy to create a rule to monitor:

Chose to configure the Registry Integrity Monitoring

Set the registry keys you wish to monitor, apply and restart.

It will capture the baseline of the current registry key, and then monitor any changes to that key, and send to your SIEM or Snare Central, providing you with the digital footprint of malicious activity.
