You were tasked to enhance the security of a network with these characteristics: • A pool of servers is accessed by numerous data centers and remote sites • The servers are accessed via a cluster of firewalls • The firewalls are configured properly and are not dropping traffic • The firewalls occasionally cause asymmetric routing of traffic within the server data center. Which technology should you recommend to enhance security by limiting traffic that could originate from a hacker compromising a workstation and redirecting flows at the servers?
