- Protection against offline dictionary attacks
- Forward secrecy to protect previously transmitted data
WPA2
While WPA3 is the newest standard, WPA2 remains widely used in Cisco wireless solutions. It offers:
- AES encryption
- CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol)
- Robust key management
WPA (Wi-Fi Protected Access)
Although less common in modern networks, WPA is still supported by some Cisco devices for backward compatibility. It provides:
- TKIP (Temporal Key Integrity Protocol)
- 128-bit encryption keys
- Dynamic key generation
WEP (Wired Equivalent Privacy)
WEP is an outdated protocol that Cisco no longer recommends due to its vulnerabilities. However, it’s important to understand its place in the evolution of wireless security:
- Uses RC4 cipher
- Supports 64-bit and 128-bit keys
- Easily crackable, making it unsuitable for modern networks
Here’s a comparison of the encryption protocols:
| Protocol | Encryption Strength | Key Length | Recommended Use |
|---|---|---|---|
| WPA3 | Strongest | Up to 192-bit | Current and future networks |
| WPA2 | Strong | 128-bit | Most existing networks |
| WPA | Moderate | 128-bit | Legacy devices only |
| WEP | Weak | 64/128-bit | Not recommended |
With this understanding of encryption protocols, we can now delve into Cisco’s proprietary encryption technologies that build upon these standards to provide even more robust security solutions.
