Cryptographic protocols, the secret behind encrypted communication, keep your online interactions safe. There are numerous types of cryptographic protocols, and enterprises use lots of different types from lots of different devices (routers, printers, IOT devices, etc.). But how do you know which protocols are being used on your network and whether they are secure enough? Here’s where TYCHON can help. The TYCHON Cryptographic Network Scanner, a new TYCHON Quantum Readiness feature, serves as your digital detective to track down your active cryptographic protocols and ensure Network Visibility.
So how does it work? The TYCHON Cryptographic Network Scanner continuously monitors data flowing through the network, acting like an eagle-eyed watchdog. It searches for specific patterns that hint at the presence of cryptographic protocols. These patterns include:
- Unusual Encryption Methods: TYCHON identifies data streams using uncommon encryption algorithms, indicating potentially unauthorized devices or custom protocols.
- Cryptographic Key Exchanges: TYCHON flags any network traffic containing key exchanges, a dead giveaway for the use of encryption.
- Device Fingerprinting: Certain devices, like Virtual Private Networks (VPNs) or secure messaging apps, often have distinct communication patterns. TYCHON’s powerful insights identify these patterns, revealing the encryption protocol types used by those devices.
By identifying these patterns, the TYCHON Cryptographic Network Scanner provides a crucial first step in understanding the cryptographic landscape of your network. This knowledge empowers you to:
- Evaluate Security Strength: Knowing the protocols and cipher suites in use allows security teams to assess their vulnerabilities. Outdated or weak protocols become prime targets for attackers, while strong, modern protocols offer better protection.
- Increase Post-Quantum Readiness: With advancements in quantum computing, current cryptographic protocols might become breakable. Identifying your protocols helps assess your organization’s preparedness for a post-quantum future. Secure protocols based on post-quantum cryptography (PQC) algorithms are crucial for long-term security.
The TYCHON Cryptographic Network Scanner, along with TYCHON’s Risk Scoring Analytics, is instrumental in exposing cryptographic protocols. This unveiled information empowers you to safeguard your network and protect your valuable data.
