A security administrator is configuring a corporate proxy server (Squid) to inspect outbound HTTPS traffic from endpoints. To perform SSL interception (Man-in-the-Middle inspection) for content filtering and DLP, what cryptographic setup must be installed on client workstations?
Clients must trust the proxy's signing CA certificate to accept the re-signed TLS certificates without browser warnings.
Why this answer
For a forward proxy to decrypt and inspect HTTPS traffic, the proxy's internal Certificate Authority (CA) root certificate must be installed into the trusted root certification authorities certificate store of each client workstation.
