COMBATS: ENCRYPTED MALWARE

What better way to launch a successful attack than to hide it from
discovery? Smart cyber criminals mask their attacks inside traffic
encrypted by SSL/TLS standards. This helps them sneak malware by a single-layer network defense.

Through June 2019, encrypted attacks were up 76% year to date over the same time period in 2018 according to the mid-year update to the 2019 SonicWall Cyber Threat Report. That’s a growing attack vector that requires critical attention.

The respected cyber security experts offer solutions to conscientiously decrypt, inspect and re-encrypt SSL and TLS traffic. For some, functionality is integrated on advanced firewalls. Other vendors sell dedicated SSL inspection appliances.

Also, be sure to ask whether the vendor offers full-proxy or artifact based inspection. The former is expensive and slows performance, while artifact-based technology — like SonicWall’s Reassembly-Free Deep Packet Inspection (RFDPI) — can stop more attacks without impacting speeds.

The approach that’s sensible for your organization will depend on your particular performance, security deployment and financial objectives.
