Use case: Making an enterprise network secure by using ICAP for remote malware inspection
The Citrix ADC appliance acts as a proxy and intercepts all the client traffic. The appliance uses policies to evaluate the traffic and forwards client requests to the origin server on which the resource resides. The appliance decrypts the response from the origin server and forwards the plain text content to the ICAP server for an antimalware check. The ICAP server responds with a message indicating “No adaptation required,” or error, or modified request. Depending on the response from the ICAP server, the content requested is either forwarded to the client, or an appropriate message is sent.
For this use case, you must perform some general configuration, proxy and SSL interception related configuration, and ICAP configuration on the Citrix ADC appliance.
General configuration
Configure the following entities:
- NSIP address
- Subnet IP (SNIP) address
- DNS name server
- CA certificate-key pair to sign the server certificate for SSL interception
Proxy server and SSL interception configuration
Configure the following entities:
- Proxy server in explicit mode to intercept all outbound HTTP and HTTPS traffic.
- SSL profile to define SSL settings, such as ciphers and parameters, for connections.
- SSL policy to define rules for intercepting traffic. Set to true to intercept all client requests.
For more details, see the following topics:
