One of the most popular targets for attackers, cybercriminals, and other bad actors is east/west network traffic. This is network traffic that originates from one internal host or network segment, and whose destination is another internal host or network segment.
North/south traffic, on the other hand, moves from an internal network out to the Internet. North/south is where organizations have historically invested, and includes security controls such as firewalls, intrusion detection/prevention systems, and proxies.
Ensuring good threat detection for east/west—or lateral—traffic has never been more important for organizations. The ability to move undetected through the network is key for successful ransomware attacks, and detecting that movement is increasingly critical as damaging and sophisticated ransomware becomes more pervasive.
Companies can choose from several methods to address the challenge of protecting lateral traffic, but each of these has limitations that ultimately make them ineffective at detecting lateral movement. One emerging method—threat deception—uses new technology and a different approach that delivers the comprehensive protection organizations need to efficiently monitor east/west network traffic.
