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 must verify:
