Policies can require integrity verification of software prior to installation, reducing risks from unverified downloads.
Blocks installation of components lacking a valid signature, mitigating download or installation of code without integrity checks.
Acquisition and maintenance portions of the strategy drive requirements for integrity verification of downloaded or supplied code.
Mandating integrity control and approved-only changes during development prevents incorporation of code or components lacking integrity validation.
Supply chain protection requires integrity verification of acquired components, directly reducing insertion or tampering of malicious code during delivery.
Reduces exposure to code obtained without integrity verification by requiring assurance processes that confirm authenticity and absence of tampering.
Tamper resistance and detection commonly include integrity verification of code and firmware obtained from external sources.
Component authenticity requires verifying origin/integrity of acquired firmware or software, directly preventing inclusion of code without integrity checks.
