VeridianOS implements multiple layers of security:

1. Capability-based access control

   • Unforgeable object references
   • Fine-grained permissions
   • Principle of least privilege

2. Memory protection

   • W^X enforcement
   • ASLR (Address Space Layout Randomization)
   • Stack guards
   • Heap isolation

3. Secure boot

   • UEFI Secure Boot support
   • Measured boot with TPM
   • Verified boot chain

4. Hardware security

   • TPM integration
   • Hardware security module support
   • Trusted execution environments

5. Network security

   • Mandatory TLS for system services
   • Certificate pinning
   • Network isolation

Our threat model considers:

• Malicious applications
• Network attackers
• Physical access attacks
• Supply chain attacks
• Side-channel attacks

• Fuzzing with AFL++ and libFuzzer
• Static analysis with clippy and cargo-audit
• Dynamic analysis with sanitizers
• Penetration testing before releases

In case of a security incident:

1. Immediate patch development
2. Security advisory publication
3. Coordinated disclosure
4. Post-mortem analysis
5. Process improvement
