Description
The web server's private key is used to prove the identity of the server to clients and securely exchange the shared secret key used to encrypt communications between the web server and clients. By gaining access to the private key, an attacker can pretend to be an authorized server and decrypt the SSL traffic between a client and the web server. As a Tomcat derivative tc Server is designed to store the server's private key in a keystore file. An important vROps keystore file is “tcserver.truststore”, and this file must be protected to only allow system administrators and other authorized users to have access to it.
