Abstract
Techniques are described for blocking unidentified encrypted communication sessions. In one embodiment, a device includes an interface to receive a packet, an application identification module to attempt to identify an application associated with the packet, an encryption detection module to determine whether the packet is encrypted when the application identification module is unable to identify an application associated with the packet, and an attack detection module to determine whether the packet is associated with a network attack, to forward the packet when the packet is not associated with a network attack, and to take a response when the packet is associated with a network attack, wherein the encryption detection module sends a message to the attack detection module that indicates whether the packet is encrypted, wherein when the message indicates that packet is encrypted, the attack detection module determines that the packet is associated with a network attack.
