At Praetorian, the confidentiality and integrity of data in transit are of paramount importance. To safeguard sensitive information during communication, we implement the latest advancements in transport security, with a focus on Transport Layer Security (TLS) 1.3. Here’s how we ensure secure and reliable communication across our platforms and services:
1. Protocol Upgrades
- Adopting TLS 1.3: We exclusively use TLS 1.3 for transport security, the latest and most secure version of the TLS protocol. It eliminates outdated features like RSA key exchange and weak ciphers, ensuring a streamlined and robust security posture.
2. Encryption in Transit
- Perfect Forward Secrecy (PFS): TLS 1.3 mandates ephemeral key exchanges, ensuring that even if a private key is compromised, past sessions remain secure.
- Secure Ciphers: Only the strongest cipher suites, such as AES-GCM and ChaCha20-Poly1305, are enabled to protect against cryptographic vulnerabilities.
3. Authentication and Trust
- Strict Certificate Validation: We leverage Certificate Authority Authorization (CAA) DNS records and strict validation practices to ensure certificates are issued only by trusted providers.
- Mutual TLS (mTLS): For critical internal services, we implement mTLS to ensure both parties in a connection are authenticated, adding an extra layer of security.
4. Performance and Efficiency
- Reduced Handshake Latency: TLS 1.3’s simplified handshake process decreases connection setup time, enhancing the user experience without compromising security.
- Zero Round-Trip Time (0-RTT): Where applicable, we utilize 0-RTT for faster reconnections, ensuring efficient performance while mitigating replay attacks with additional safeguards.
5. Compliance and Governance
- Strong Compliance Standards: Our TLS 1.3 implementation adheres to stringent industry compliance standards, including PCI DSS, GDPR, and SOC 2.
- Continuous Monitoring: We actively monitor compliance with evolving regulatory requirements to ensure our security posture remains ahead of the curve.
6. Monitoring and Incident Response
- Real-Time Threat Detection: Integrated monitoring systems detect anomalies in TLS traffic, such as downgrade attempts or suspicious activities.
- Comprehensive Logging: Detailed logs of TLS handshake and session activities are maintained for auditing and rapid response to potential threats.
