Security Documentation

This document outlines the security model, threat model, and security practices for the Mandalorian Project.

Security Model

Core Principles

Zero Trust Architecture - No component is inherently trusted - All interactions are verified and authorized - Continuous monitoring and validation

Defense in Depth - Multiple security layers working together - No single point of failure - Graceful degradation under attack

Formal Verification - seL4 microkernel provides mathematical security guarantees - Cryptographic operations are formally verified - System invariants are provably maintained

Security Properties

Integrity - Cryptographic verification of all boot components - Merkle tree integrity for system state - Tamper-evident audit logging

Confidentiality - seL4 capability-based isolation - Encrypted storage and communication - Memory protection and access controls

Availability - Graceful degradation under attack - Resource quotas and rate limiting - Fault-tolerant design

Accountability - Immutable audit trails - Non-repudiable logging - Forensic analysis capabilities

Threat Model

Assumptions

• Hardware root of trust (secure boot ROM)
• seL4 microkernel formal verification
• Physical security of the device
• Trusted supply chain for hardware/firmware

Threat Actors

External Attackers - Network-based attacks - Malicious applications - Supply chain compromises - Physical attacks

Internal Threats - Malicious or compromised applications - Privilege escalation attempts - Side-channel attacks - Resource exhaustion

Attack Vectors

Boot Chain Attacks - Bootkit installation - Firmware modification - Secure boot bypass - Supply chain attacks

Runtime Attacks - Application exploits - IPC manipulation - Resource exhaustion - Side-channel leakage

System Compromise - Kernel exploits - Rootkit installation - Backdoor insertion - Data exfiltration

Attack Surface

Minimized Attack Surface - seL4 microkernel (minimal TCB) - Capability-based access control - Application sandboxing - Hardware security modules

Security Components

BeskarCore Security

Verified Boot Chain

// Boot integrity verification
int verify_boot_chain(void) {
    // Verify bootloader signature
    if (verify_signature(bootloader, bootloader_sig) != 0) {
        return ERROR_VERIFICATION_FAILED;
    }

    // Verify kernel integrity
    if (verify_kernel_integrity() != 0) {
        return ERROR_VERIFICATION_FAILED;
    }

    // Chain of trust established
    return ERROR_SUCCESS;
}

Shield Ledger

// Tamper-evident logging
int ledger_append_secure(const uint8_t *data, size_t len) {
    // Create log entry with timestamp and metadata
    ledger_entry_t entry = {
        .timestamp = time(NULL),
        .data = data,
        .len = len,
        .hash = sha3_256(data, len)
    };

    // Append to Merkle tree
    return ledger_append_entry(&entry);
}

VeridianOS Security

App Sandboxing

// Capability-based isolation
sandbox_t *create_secure_sandbox(const char *app_id) {
    sandbox_t *sandbox = sandbox_create(app_id);

    // Minimal capabilities by default
    sandbox_revoke_all_capabilities(sandbox);

    // Grant only required permissions
    sandbox_grant_capability(sandbox, CAP_NETWORK_READ);
    sandbox_grant_capability(sandbox, CAP_STORAGE_READ);

    return sandbox;
}

IPC Mediation

// Aegis IPC monitoring
int monitor_ipc_secure(const char *sender, const char *receiver,
                      const void *data, size_t len) {
    // Validate sender permissions
    if (!aegis_check_permission(sender, PERMISSION_IPC_SEND)) {
        return ERROR_PERMISSION_DENIED;
    }

    // Inspect message content
    if (aegis_inspect_message(data, len) != 0) {
        LOG_WARN("Suspicious IPC message blocked");
        return ERROR_SECURITY_VIOLATION;
    }

    // Allow communication
    return ipc_send(sender, receiver, data, len);
}

Aegis Security Monitor

Runtime Monitoring

// Continuous security validation
void aegis_monitor_loop(void) {
    while (1) {
        // Check system integrity
        if (verify_system_integrity() != 0) {
            aegis_trigger_alert(ALERT_INTEGRITY_COMPROMISED);
        }

        // Monitor resource usage
        if (check_resource_anomalies() != 0) {
            aegis_trigger_alert(ALERT_RESOURCE_ANOMALY);
        }

        // Validate running processes
        if (validate_process_states() != 0) {
            aegis_trigger_alert(ALERT_PROCESS_ANOMALY);
        }

        sleep(1); // Monitor interval
    }
}

Security Practices

Secure Coding Guidelines

Input Validation

// Always validate inputs
int secure_function(const uint8_t *data, size_t len) {
    if (data == NULL || len == 0 || len > MAX_DATA_SIZE) {
        return ERROR_INVALID_ARGUMENT;
    }

    // Additional validation
    if (!is_valid_utf8(data, len)) {
        return ERROR_INVALID_ARGUMENT;
    }

    // Process validated data
    return process_data(data, len);
}

Error Handling

// Secure error handling
int secure_operation(void) {
    error_context_t *error = NULL;

    if (operation_that_can_fail() != 0) {
        error = error_create(ERROR_OPERATION_FAILED,
                           "Operation failed",
                           __FILE__, __FUNCTION__, __LINE__);
        goto cleanup;
    }

    // Success path
    result = ERROR_SUCCESS;

cleanup:
    if (error) {
        error_log(error);
        error_free(error);
    }
    return result;
}

Cryptographic Hygiene

// Secure key handling
void secure_key_usage(void) {
    uint8_t key[32];

    // Generate random key
    if (crypto_random_bytes(key, sizeof(key)) != 0) {
        LOG_ERROR("Failed to generate key");
        return;
    }

    // Use key for operation
    crypto_operation(key);

    // Securely erase key
    memset(key, 0, sizeof(key));
    crypto_explicit_bzero(key, sizeof(key));
}

Security Testing

Unit Security Tests

// Test cryptographic functions
void test_crypto_security(void) {
    // Test with known test vectors
    uint8_t digest[32];
    sha3_256(digest, test_data, sizeof(test_data));

    assert(memcmp(digest, expected_digest, 32) == 0);

    // Test edge cases
    assert(sha3_256(NULL, test_data, sizeof(test_data)) == ERROR_INVALID_ARGUMENT);
    assert(sha3_256(digest, NULL, sizeof(test_data)) == ERROR_INVALID_ARGUMENT);
}
