FedRAMP is the federal cloud-vendor gating requirement. Without an ATO (Authority to Operate), you cannot sell to federal agencies. Audit logging is one of the most heavily scrutinized control families in FedRAMP assessments.
AU (Audit and Accountability) controls are the largest control family in FedRAMP — 16 controls including AU-2, AU-3, AU-9, AU-12
FedRAMP Moderate baseline requires log integrity protection (AU-9) — cryptographic hash chains are the standard mechanism
FedRAMP continuous monitoring (ConMon) requires monthly log review evidence
JAB (Joint Authorization Board) authorizations require evidence of effective audit logging across all assessment phases
FedRAMP is the U.S. government program that standardizes security assessment and authorization for cloud products and services. Based on NIST SP 800-53, FedRAMP imposes rigorous audit logging requirements across three impact levels: Low, Moderate, and High. The audit and accountability (AU) control family is one of the most scrutinized areas during FedRAMP authorization. Cloud service providers must demonstrate comprehensive logging, log protection, and log analysis capabilities. FedRAMP authorization can take 6-18 months and is required for any cloud service used by federal agencies.
Retention requirement: Minimum 1 year online, 3 years total (per NIST SP 800-53 AU-11)
All authentication events (success and failure)
All privileged access and admin actions
All system configuration changes
All security control modifications
All data import / export events
Identify events that the system is capable of logging in support of the audit function. Events include password changes, failed logon attempts, access control changes, administrative privilege usage, and system startup/shutdown.
AuditKit: Configurable event capture with comprehensive audit event taxonomy
Audit records must contain the type of event, when the event occurred, where the event occurred, the source of the event, the outcome, and the identity of associated subjects.
AuditKit: Structured event schemas capture all required fields with extensible metadata
Protect audit information and audit logging tools from unauthorized access, modification, and deletion. Implement cryptographic protections for audit integrity.
AuditKit: SHA-256 hash chains and Merkle tree proofs provide cryptographic integrity protection
Review and analyze audit records for indications of inappropriate or unusual activity. Report findings to designated officials.
AuditKit: React-based audit viewer with filtering, search, and export capabilities
SHA-256 hash chains and Merkle tree proofs provide mathematical proof that audit records have not been altered. This is increasingly the standard mechanism for satisfying FedRAMP log-integrity requirements — assessors no longer accept policy-only controls.
GovTech platforms typically serve multiple customers from shared infrastructure. AuditKit enforces strict tenant isolation at the infrastructure level — your customers' audit data is logically separated, satisfying data segregation requirements common in FedRAMP assessments.
Stream audit events to Splunk, Datadog, Elastic, or any SIEM your security team uses. FedRAMP increasingly requires real-time monitoring, not just retained logs — AuditKit ships native streaming with at-least-once delivery semantics.
The AuditKit React viewer gives FedRAMP auditors a clear interface for evidence review — filtered queries, integrity verification UI, and exportable evidence packages. Cuts auditor request cycles by 60-80% in typical engagements.
FedRAMP is based on NIST SP 800-53 Rev 5, which contains 20 audit and accountability (AU) controls
FedRAMP Moderate (the most common level) requires implementation of all 20 AU controls
The Joint Authorization Board (JAB) and agency authorizing officials review audit logging capabilities
FedRAMP Rev 5 transition deadline requires all CSPs to update controls by 2024
AU-2 (event types), AU-3 (event content), AU-9 (protection of audit information), and AU-12 (audit record generation) are the core requirements. AU-9 specifically requires that audit logs be protected from unauthorized modification — cryptographic hash chains and Merkle tree proofs are the canonical implementation.
FedRAMP Moderate baseline requires audit log retention for at least 1 year online and 3 years total. Some agency-specific tailoring extends retention to 7 years. AuditKit's tiered retention supports the full FedRAMP retention spectrum.
FedRAMP requires implementation of NIST SP 800-53 AU controls including AU-2 (Event Logging), AU-3 (Content of Audit Records), AU-6 (Review and Analysis), AU-9 (Protection of Audit Information), and AU-12 (Audit Record Generation). AuditKit addresses these controls with cryptographic hash chains, structured event schemas, SIEM streaming, and a built-in audit viewer.
FedRAMP requires implementation of NIST SP 800-53 AU controls including AU-2 (event logging), AU-3 (content requirements), AU-6 (review and analysis), AU-9 (protection of audit information), and AU-12 (audit record generation). AuditKit provides all of these capabilities with SHA-256 hash chains for cryptographic integrity.
CMMC 2.0 is the DoD's mandatory certification for contractors handling Controlled Unclassified Information (CUI). Phased rollout means thousands of defense-adjacent vendors must achieve CMMC Level 2 by 2026-2028.
State and local government procurement often requires SOC 2 Type II as a baseline before FedRAMP becomes relevant. SOC 2 is the stepping stone to government sales for many govtech SaaS companies.
