Security Model

Overview

Anya's security model is built on the principles of zero-trust architecture, defense in depth, and secure by default. The system implements multiple layers of security to protect sensitive data and operations.

Key Security Features

Security Architecture

Encryption

All sensitive data is encrypted using industry-standard algorithms:

use anya::security::{Encryption, EncryptionType};

impl SecurityManager {
    /// Initialize encryption with specified algorithm
    pub fn init_encryption(&self) -> Result<()> {
        let encryption = Encryption::new(
            EncryptionType::Aes256Gcm,
            &self.config.encryption_key
        )?;
        
        // Configure encryption parameters
        encryption.set_params(
            iterations: 100_000,
            memory_size: 64 * 1024,
            parallelism: 4
        )?;
        
        Ok(())
    }
}

Key Management

Secure key management includes:

Authentication

use anya::security::{Auth, AuthMethod};

impl SecurityManager {
    /// Configure authentication methods
    pub async fn setup_auth(&self) -> Result<()> {
        let auth = Auth::new()
            .with_method(AuthMethod::Password)
            .with_method(AuthMethod::Totp)
            .with_method(AuthMethod::HardwareKey);
        
        auth.enforce_mfa(true);
        auth.set_session_timeout(Duration::from_secs(3600));
        
        Ok(())
    }
}

Implementation Details

Secure Storage

use anya::security::storage::SecureStorage;

impl SecureStorage {
    /// Store sensitive data securely
    pub async fn store(&self, key: &str, data: &[u8]) -> Result<()> {
        // Encrypt data
        let encrypted = self.encryption.encrypt(data)?;
        
        // Store with access controls
        self.storage
            .with_acl(AccessLevel::Confidential)
            .store(key, &encrypted)
            .await?;
        
        // Log access
        self.audit_log.record(
            Action::Store,
            key,
            self.current_user()?
        ).await?;
        
        Ok(())
    }
}

Audit Logging

use anya::security::audit::{AuditLog, LogLevel};

impl AuditLog {
    /// Record security-relevant events
    pub async fn record(
        &self,
        action: Action,
        resource: &str,
        user: &User
    ) -> Result<()> {
        let event = AuditEvent::new()
            .action(action)
            .resource(resource)
            .user(user)
            .timestamp(Utc::now())
            .metadata(self.get_context()?);
        
        self.logger
            .log(LogLevel::Security, event)
            .await?;
        
        Ok(())
    }
}

Security Best Practices

Configuration

# Security configuration example
[security]
encryption_type = "aes256gcm"
key_derivation = "argon2id"
mfa_required = true
session_timeout = 3600
audit_level = "high"

[storage]
encryption_at_rest = true
secure_delete = true
backup_encryption = true
