Access Control Lists (ACLs) used in Packet Filtering Firewalls can degrade performance. True or False?
True
False
True. These Access control lists (ACL's) check each packet which takes time and degrades performance
A firewall is a network security device that works to protect an organization's internal network from both unauthorized and malicious users. It functions by examining all packets that enter any one of its incoming interfaces and comparing the structure of the packet against a set of predefined rules. Each rule specifies if a packet corresponding to the rule is to be permitted or denied. This set of rules is called an access control list (ACL) and it forms the basis of a firewall's policy. Incorrect configuration of the firewall can lead to redundant rules which cause performance degradation
*** Scenario is unclear. Degrade performance of the firewall? Doubtful. Granted that ANY network device which is misconfigured can cause problems, but ACLs by definition are not a misconfiguration, and proper configurations will not have a noticeable effect on performance to the end user. << Scenario is crystal clear. ACL's absolutely degrade performance - whether it is "noticeable" by a human, or not. Efforts to move this type of access control logic into ASICs is clear evidence that this question is true.
