03.14.01E Software, Firmware, and Information Integrity

Statement

• Employ integrity verification tools to detect unauthorized changes to the following software, firmware, and information: {{ insert: param, A.03.14.01E_prm_1 }}.

• Take the following actions when unauthorized changes to the software, firmware, and information are detected: {{ insert: param, A.03.14.01E_prm_2 }}.

Guidance

Verifying the integrity of security-critical or essential software is an important capability since corrupted software is the primary attack vector used by adversaries to undermine or disrupt the proper functioning of systems. Unauthorized changes to software, firmware, and information can occur due to errors or malicious activity. Software includes boot firmware, operating systems with key internal components (e.g., kernels or drivers), middleware, and applications. Firmware interfaces include Unified Extensible Firmware Interface (UEFI) and Basic Input/Output Systems (BIOS). Information includes CUI and metadata that contains security attributes associated with information. Integrity-checking mechanisms—including parity checks, cyclical redundancy checks, cryptographic hashes, and associated tools—can automatically monitor the integrity of systems and hosted applications. There are many ways to verify software integrity throughout the system development life cycle. Root of trust mechanisms (e.g., secure boot, trusted platform modules, UEFI) verify that only trusted code is executed during boot processes. The employment of cryptographic signatures ensures the integrity and authenticity of critical software that stores, processes, or transmits, CUI. This requirement is sourced to a control tailored out of the SP 800-53B .13 moderate baseline in SP 800-171.

Statement

• (includes preempt) Ensure that the threat event does not have an impact.

  • Reduce likelihood of occurrence and/or reduce likelihood of impact.

  • The adversary’s efforts or resources cannot be applied or are wasted.

• (includes detect) Reduce risk due to ignorance of threat events and possible replicated or similar threat events in the same or similar environments.

  • Reduce likelihood of impact.

  • The adversary loses the advantage of stealth as defenders are better prepared by developing and sharing threat intelligence.
