Abstract
In one example embodiment, a proxy for a network obtains a traffic flow. The proxy determines whether a security policy in a whitelist for the traffic flow is active. If it is determined that the security policy for the traffic flow is active, the proxy selectively decrypts the traffic flow to produce one or more traffic flow attributes and, based on the one or more traffic flow attributes, determines whether the traffic flow is potentially malicious.
