The Blind State of Rising SSL/TLS Traffic: Are Your Cyber Threats Visible?
Traditional security gateways, network firewalls, and intrusion prevention systems are increasingly blinded by the rising tide of encrypted traffic, and some enterprise chief information security officers (CISOs) are alarmed by this lack of visibility. The growing volume of bandwidth associated with cloud-based services and the rising amount of encrypted traffic are a double blow to these traditional security solutions. Encrypted traffic blinds prevention systems from hacker communications to command and control infrastructure and attacker movement within an organization to critical resources. This traffic also prevents many of these network security appliances from identifying signs of targeted attacks, malicious scripts, and other criminal tools and tactics used to infiltrate corporate networks.
