Government Contract E-Signatures: FAR, DFARS, and Federal Compliance

Government contractors face unique challenges with electronic signatures, balancing FAR Part 4 requirements, agency-specific rules, and the need for robust security and audit readiness.

FAR Part 4: Electronic Signatures in Federal Acquisition

FAR 4.2001 (Electronic Signatures)

Establishes that electronic signatures have the same legal effect as handwritten signatures for federal government contracts, provided:

FAR 4.7000-4.7004 (Contract Files)

DFARS: Defense-Specific Requirements

DFARS 252.204-7012 (Safeguarding Covered Defense Information)

Requires contractors to:

NIST SP 800-171 Controls for E-Signature Systems

| Control | Requirement |

|---|---|

| 3.5.1 | Unique identification of users |

| 3.5.2 | Multi-factor authentication |

| 3.5.3 | Device identification and authentication |

| 3.13.1 | Boundary protection |

| 3.13.11 | Session lock after inactivity |

| 3.13.16 | Encryption of CUI in transit |

GSA Schedule and MAS

Contractors using GSA Schedules or Multiple Award Schedules (MAS) must:

Identity Proofing Requirements

Government contracts often require higher identity assurance levels:

NIST 800-63 Identity Assurance Levels (IAL)

| IAL | Requirement | Use Case |

|---|---|---|

| IAL1 | Self-asserted identity | Low-risk transactions, unclassified |

| IAL2 | Remote identity proofing | Most federal contracts, CUI |

| IAL3 | In-person identity proofing | Classified, high-security contracts |
