Solution 1

As a cybersecurity professional, I would recommend using the following 802.11 security protocols for a strong level of security:

  1. WPA3 (Wi-Fi Protected Access 3): This is the latest and most secure protocol currently available. It provides robust authentication and increased cryptographic strength for highly sensitive data markets. It also includes a feature called Simultaneous Authentication of Equals (SAE) which protects against password guessing attempts by third parties.

  2. WPA2-Enterprise: This version of WPA2, unlike WPA2-Personal, uses IEEE 802.1X for higher security. This makes it more suitable for enterprise environments where a higher level of security is required.

  3. EAP (Extensible Authentication Protocol): This is not a protocol itself, but it is used in conjunction with RADIUS server for authentication. EAP provides more secure authentication methods for WPA2-Enterprise networks.

Remember, the choice of protocol will depend on the specific needs and infrastructure of your company. It's also important to keep all devices and software up-to-date to ensure the highest level of security.

Solution 2

As a cybersecurity professional, I would recommend using the following 802.11 security protocols for a strong level of security:

  1. WPA3 (Wi-Fi Protected Access 3): This is the latest and most secure protocol currently available. It provides robust authentication and increased cryptographic strength for highly sensitive data markets. It also includes a feature called Simultaneous Authentication of Equals (SAE) which protects against password guessing attempts.

  2. WPA2-Enterprise: This version of WPA2, which requires each user to authenticate with a unique credential, is also a good option for businesses. It uses IEEE 802.1X, which offers enterprise-grade authentication.

  3. WPA2 + AES: When WPA2 is combined with AES (Advanced Encryption Standard), this protocol offers a high level of security. AES is a secure encryption standard supporting 128, 192, and 256-bit encryption.

  4. EAP (Extensible Authentication Protocol): EAP is an authentication framework frequently used in wireless networks and Point-to-Point connections. It provides for an arbitrary authentication method such as token cards, smart cards, certificates, and public key authentication.

Avoid using WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access) as they have known vulnerabilities and are considered outdated.

Remember, the choice of protocol will also depend on the capabilities of your wireless equipment and the nature of the data you are protecting.
