What Do DISA STIG Compliance Levels Indicate?

DISA STIG compliance is structured into three distinct levels called categories. These categories provide insight into the potential severity of failing to address specific vulnerabilities.

The categories are arranged from the most critical to the least:

  • Category I
  • Category II
  • Category III

Category I

Category I refers to vulnerabilities that have an immediate and direct impact on the confidentiality, availability, or integrity of systems and data. These vulnerabilities can potentially enable unauthorized access to classified information or facilities. Hackers look for these vulnerabilities to gain access to the internal systems and launch denial-of-service attacks.

These risks are most severe, with the potential for loss of life, damage to facilities, and critical mission-failure issues. Failure to mitigate these risks could result in a complete loss of reputation and revenue for the business. Category I issues become critical:

  • When the affected systems hold crucial importance in business operations.
  • When the loss of systems could result in show-stopping failures.

Category II

Category II covers vulnerabilities that can result in potential loss of confidentiality, availability, or integrity. These vulnerabilities might lead to the following:

  • Escalation to a Category I vulnerability (especially when unaddressed for long).
  • Personal injuries, equipment, or facility damage.
  • Compromised mission performance.

Category III

Category III includes vulnerabilities that weaken protective measures and could lead to loss of data and systems confidentiality, availability, or integrity. These vulnerabilities can potentially:

  • Progress to a Category II vulnerability.
  • Cause delays in recovering from outages.
  • Impact on the accuracy of data and information.

Understanding these categories helps prioritize allocating efforts and resources to address vulnerabilities within a DISA STIG compliance framework.

How to Implement DISA STIG Guidelines

DISA STIGs provide in-depth technical instructions to mitigate security risks and address known vulnerabilities. These guidelines are presented as a configuration checklist. For many businesses, running through these detailed checklists can be time and resource-intensive due to the many controls involved.

The complexity arises from maintaining compliance with new iterations and the varying effort required to meet each stipulation. STIGs may encompass directives regarding minimal training levels for personnel, update frequencies, and configuration settings.

A Four-step Framework for Implementing DISA STIGs

The main challenge in implementing the recommendations of DISA STIGs is the lack of a standard framework that businesses could adopt for their unique requirements.

We present the following framework that businesses could modify to suit the requirements of their industries and operational scenarios. 

Find Relevant STIGs

Navigate and download STIGs from the updated STIG catalog maintained by DISA. Always select the latest edition or one suitable for the specific device version under configuration. 

STIG updates are typically released quarterly to address emerging vulnerabilities and software updates from vendors. Newer versions of specific STIGs have revision histories detailing changes from previous documents. The documents are available for download as ZIP files.

Each STIG includes an executive summary for context, often explaining critical concepts and terminology. The document also provides detailed steps and controls required for achieving compliance and categorizing risks associated with each control.

Use Test Environments Before Pushing Changes

Organizations often operate complex network environments with various software and device providers. Due to the intricate nature of these networks, any changes to network settings and configurations should always undergo testing to avoid unintended consequences. Failure to do so could result in loss of functionality.

STIG configurations generally prioritize security over other factors, which might reduce software or device functionality. 

Configuration changes should undergo thorough testing in a staging environment before being applied to the live network. Introducing changes in a controlled test environment is crucial for identifying and rectifying functionality loss before implementation in the live environment.

Evaluate STIG Compliance

Security teams can leverage automated tools to streamline STIG compliance checks, expediting the audit process. These tools scan and audit network devices to assess compliance with pre-set configuration rules. Some scanning tools may require STIGs to be uploaded in Security Content Automation Protocol (SCAP) format.

A compliance benchmark is a foundation for scans or audits, where the automated process highlights non-compliance and related issues. Regularly scheduled compliance scans or audits are integral to the organization’s cybersecurity checklists.

For STIGs lacking a SCAP version, manual compliance checks are necessary. The STIG outlines the criteria for a passing state, the essential implementation steps, the failure state, and its resolution. During this process, auditors meticulously evaluate each control against the STIG rules.

Sustain STIG Compliance

Software and hardware products undergo continuous updates that eliminate vulnerabilities and bugs, and introduce new features. However, these updates can potentially introduce previously unknown vulnerabilities and challenges into the systems.

STIGs are updated quarterly to align with new vendor versions, vulnerabilities, and threats. Organizations frequently encounter new STIGs tailored to new software versions. 

The ultimate challenge in maintaining STIG compliance is to follow the guidelines and ensure risk mitigation as software and hardware evolve. Organizations should stay vigilant about updates that impact their systems and establish continuous compliance monitoring.
