BEST PRACTICES TO CONFIGURE BIG-IP LTM SYSTEMS TO ENCRYPT HTTP PERSISTENCE
COOKIES

Release Date
October 10, 2024


CISA has observed cyber threat actors leveraging unencrypted persistent cookies
managed by the F5 BIG-IP Local Traffic Manager (LTM) module to enumerate other
non-internet facing devices on the network. F5 BIG-IP is a suite of hardware and
software solutions designed to manage and secure network traffic. A malicious
cyber actor could leverage the information gathered from unencrypted persistence
cookies to infer or identify additional network resources and potentially
exploit vulnerabilities found in other devices present on the network.  
 

CISA urges organizations to encrypt persistent cookies employed in F5 BIG-IP
devices and review the following article for details on how to configure the
BIG-IP LTM system to encrypt HTTP cookies(link is external). Additionally, F5
has developed an iHealth heuristic to detect and alert customers when cookie
persistence profiles do not have encryption enabled. BIG-IP iHealth(link is
external) is a diagnostic tool that "evaluates the logs, command output, and
configuration of a BIG-IP system against a database of known issues, common
mistakes, and published F5 best practices" to help users verify the optimal
operation of their BIG-IP systems.
