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.

Three-Component Security Architecture#

Security Control Matrix#

Threat Model and Security Boundaries#

Attack Surface Analysis#

Primary Attack Vectors:

1. Process Enumeration Attacks: Attempts to exploit privileged process access
2. SQL Injection: Malicious detection rules targeting the SQL engine
3. IPC Communication Attacks: Exploitation of inter-process communication
4. Database Tampering: Attempts to modify stored process data or audit logs
5. Privilege Escalation: Exploitation of temporary elevated privileges
6. Network-based Attacks: Exploitation of alert delivery channels

Security Boundary Enforcement#

Process Isolation:

• procmond runs in isolated process space with minimal privileges
• daemoneye-agent operates in user space with restricted database access
• daemoneye-cli has no direct system access, only IPC communication

Network Isolation:

• procmond: Zero network access (air-gapped)
• daemoneye-agent: Outbound-only connections for alert delivery
• daemoneye-cli: No network access, local IPC only

Data Access Controls:

• Audit ledger: Write-only for procmond, read-only for others
• Event store: Read/write for daemoneye-agent, query-only for daemoneye-cli
• Configuration: Hierarchical access with validation

Threat Mitigation Strategies#

Memory Safety:

• Rust's ownership system prevents buffer overflows and use-after-free
• Zero unsafe code policy with isolated exceptions
• Comprehensive testing including fuzzing and static analysis

Input Validation:

• Protobuf schema validation for all IPC messages
• SQL AST parsing with whitelist-based function approval
• CLI argument validation with type safety

Cryptographic Protection:

• BLAKE3 hashing for all audit entries
• Merkle tree integrity verification
• Optional Ed25519 signatures for external verification

Component Security Design#

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:

• Cryptographic integrity verification reports
• Privilege separation documentation
