I read an interesting statement on http://www.cisco.com/en/US/products/hw/vpndevc/ps4077/products_data_sheet0900aecd801e6a45.html:
• Unique network collaboration-Enhances scalability and resiliency through network collaboration, including efficient traffic capture techniques, load-balancing capabilities, and visibility into encrypted traffic.
mcafee does ssl inspection [http://www.mcafee.com/us/local_content/white_papers/wp_encr_th_prot.pdf] by pushing a copy of the https server's prv key to the sensor & decrypting incoming ssl traffic. i don't see any such procedure for the 4200 devices. am i missing something? no cisco SE's seem to respond.
