Security Leaders Must Address Threats From Rising SSL Traffic

Published: 09 December 2013

Summary

SSL encryption provides confidentiality for the encapsulated traffic but weakens enterprise defense-in-depth efficiency, exposing endpoints and DMZ servers to threats from outbound and inbound traffic. This research will help enterprise security leaders to create a traffic decryption strategy.

Included in Full Research

  • Impacts
  • An increasing share of enterprise network traffic is encrypted, creating gaps in defense-in-depth effectiveness that security leaders should not ignore
  • Complex sets of laws and regulations on privacy, along with a high risk of conflict with employees, kill most security leaders' outbound Web traffic decryption projects
    • Decrypting Traffic
    • Employee Surveillance
    • Data Retention
    • Prepare for Environment Changes
  • Security leaders face limited technology choices for enterprise network traffic decryption, and these solutions often induce high costs and poor user experience
    • Decrypting Traffic Has Multiple Effects on the Enterprise Network
    • Mitigation Techniques Exist but Are Not Yet Mature
