Rolling DFA upgrades
Starting from dynamic update 1393, the handling of situations appearing in multiple contexts is improved.
To avoid the same traffic data to be matched against multiple DFA's, all DFA's are being modified.
When large number of DFAs change at the same time, the temporary memory requirement during a policy installation or refresh increases.
To avoid not enough available memory on low end NGFW appliances these changes on DFA's are implemented gradually over the course of 10 dynamic update packages.
With low end NGFW appliances, especially N110 and N115, it is recommended to upgrade to NGFW version 6.8.2 or higher to better address new policy when there is not enough memory for both old and new policy.
A large number of DFAs might change at the same time if there is a large gap between activating dynamic update packages and the subsequent policy refresh.
See knowledge base article 18570.
This update package improves the detection capabilities of the Forcepoint LLM system.
