Secure Coding Guidelines

Input Validation

  • Validate all inputs using a whitelist approach
  • Use type-safe parameters
  • Implement proper error handling
// Good: Strongly typed input
fn process_transaction(tx: Transaction) -> Result<(), Error> {
    // ...
}

// Bad: Raw string input
fn process_transaction(tx: String) -> Result<(), Error> {
    // ...
}

Memory Safety

  • Prefer Rust's ownership model
  • Use #[non_exhaustive] for public enums
  • Implement Drop for sensitive data
pub struct PrivateKey {
    key: [u8; 32],
}

impl Drop for PrivateKey {
    fn drop(&mut self) {
        // Securely zeroize memory
        self.key.zeroize();
    }
}

Cryptographic Standards

Key Management

  • Use well-established cryptographic libraries
  • Generate keys with sufficient entropy
  • Implement secure key storage
use rand::rngs::OsRng;
use ed25519_dalek::Keypair;

let mut csprng = OsRng;
let keypair: Keypair = Keypair::generate(&mut csprng);

Hashing

  • Use strong hash functions (SHA-256, BLAKE3)
  • Always use salt with password hashing
  • Use constant-time comparison functions
use sha2::{Sha256, Digest};
use subtle::ConstantTimeEq;

fn verify_hash(input: &[u8], expected_hash: &[u8]) -> bool {
    let mut hasher = Sha256::new();
    hasher.update(input);
    let result = hasher.finalize();
    result.ct_eq(expected_hash).into()
}

Authentication & Authorization

Authentication

  • Implement multi-factor authentication
  • Use secure password policies
  • Implement rate limiting

Authorization

  • Follow principle of least privilege
  • Use role-based access control (RBAC)
  • Implement proper session management

Data Protection

Encryption

  • Encrypt sensitive data at rest
  • Use authenticated encryption
  • Implement proper key rotation

Secure Storage

  • Use platform secure storage when available
  • Never store sensitive data in logs
  • Implement secure memory management

Network Security

Secure Communication

  • Enforce TLS 1.2+
  • Use certificate pinning
  • Implement secure WebSocket connections

API Security

  • Validate all API inputs
  • Implement rate limiting
  • Use proper authentication tokens

Incident Response

Reporting Security Issues

Report security issues to security@anya.org.

Include:

  • Description of the vulnerability
  • Steps to reproduce
  • Impact assessment
  • Any mitigation suggestions

Security Updates

  • Regular security audits
  • Timely security patches
  • Security bulletins for users

Compliance

Standards Compliance

  • OWASP Top 10
  • NIST Cybersecurity Framework
  • GDPR compliance for user data
  • Financial industry regulations

Security Audits

  • Regular third-party audits
  • Automated security scanning
  • Penetration testing

Security Tools

Static Analysis

# Run clippy with security lints
cargo clippy -- -D warnings -D clippy::unwrap_used

# Run security audit
cargo audit

Dynamic Analysis

# Fuzz testing
cargo install cargo-fuzz
cargo fuzz run my_target

# Address Sanitizer
RUSTFLAGS="-Zsanitizer=address" cargo test
