| Without integrity protection, unauthorized changes may be made to the log files and reliable forensic analysis and discovery of the source of malicious system activity may be degraded.
Remote access (e.g., RDP) is access to DoD nonpublic information systems by an authorized user (or an information system) communicating through an external, non-organization-controlled network. Remote access methods include broadband and wireless.
Integrity checks include cryptographic checksums, digital signatures, or hash functions. Federal Information Processing Standard (FIPS) 186-4, Digital Signature Standard (DSS), specifies three NIST-approved algorithms: DSA, RSA, and ECDSA. All three are used to generate and verify digital signatures in conjunction with an approved hash function. |
