Security Architecture Overview#

Core Security Principles#

DaemonEye is built on fundamental security principles that guide every
aspect of its design and implementation:
Principle of Least Privilege: Each component operates with the
minimum privileges required for its specific function, with immediate
privilege dropping after initialization.
Defense in Depth: Multiple layers of security controls protect
against various attack vectors, from memory safety to network isolation.
Fail-Safe Design: The system fails securely, maintaining monitoring
capabilities even when individual components experience issues.
Audit-First Approach: All security-relevant events are
cryptographically logged with tamper-evident integrity guarantees.
Zero Trust Architecture: No component trusts another without
explicit verification, and all communications are authenticated and
encrypted.

US Government ISSO Considerations#

This section explains how DaemonEye addresses specific concerns and
requirements that US Government Information System Security Officers
(ISSOs) must consider when evaluating security monitoring solutions for
federal systems.

What DaemonEye Provides for ISSOs#

Audit-Grade Evidence Collection:
DaemonEye's Merkle tree audit ledger provides cryptographically
verifiable evidence that ISSOs can use for compliance reporting and
forensic investigations. The system generates inclusion proofs for every
audit event, enabling ISSOs to demonstrate data integrity and
non-repudiation to auditors and investigators.
Minimal Attack Surface for High-Risk Environments:
The three-component architecture with privilege separation means that
even if one component is compromised, the system maintains security
boundaries. This is particularly important for ISSOs managing systems
with sensitive data, as it limits the blast radius of potential security
incidents.
Airgapped Operation Capability:
DaemonEye operates entirely offline, making it suitable for classified
environments where network connectivity is restricted. ISSOs can deploy
the system in airgapped networks without compromising security or
functionality.

FISMA Compliance Support#

NIST SP 800-53 Control Implementation:
DaemonEye directly implements several NIST SP 800-53 controls that ISSOs

SC-7 (Boundary Protection): Outbound-only network connections with no listening ports
AC-6 (Least Privilege): Minimal privilege implementation with immediate privilege dropping
Evidence for ATO Packages:

need for Authorization to Operate (ATO) packages, including:
Cryptographic integrity verification reports
Privilege separation documentation
Input validation test results
Performance benchmarks under load
