Authentication mechanism absence or evasion - WiFi

Description​

Te system has one old authentication mechanism that can be bypassed and be vulnerable to an intrusion. An attacker can gain access to the network and see communication traffic, whether encrypted or not.

Impact​

Set a fragil encryption technique in authentication become a target for exploitation.

Recommendation​

  • Select the most secure authentication method that is supported by your wireless network clients.
  • Set up strong encryption algorithms in order to enforce authentication protocol.

Threat​

Unauthenticated internal attacker.

Expected Remediation Time​

⌚ 120 minutes.

Compliant code​

A secure authentication method is provided

<authentication>
  <anonymousAuthentication enabled="false" />
  <basicAuthentication enabled="false" />
  <clientCertificateMappingAuthentication enabled="false" />
  <digestAuthentication enabled="false" />
  <iisClientCertificateMappingAuthentication enabled="false">
  </iisClientCertificateMappingAuthentication>

  <windowsAuthentication enabled="true">
    <providers>
      <add value="Negotiate" />
      <add value="NTLM" />
    </providers>
  </windowsAuthentication>
</authentication>

Non compliant code​

The application uses an unsafe encryption method as authentication protocol

<authentication>
  <anonymousAuthentication enabled="true" />
  <basicAuthentication enabled="true" />
  <clientCertificateMappingAuthentication enabled="false" />
  <digestAuthentication enabled="false" />
  <iisClientCertificateMappingAuthentication enabled="false">
  </iisClientCertificateMappingAuthentication>
</authentication>
