Show Answer Hide Answer
Correct Answer: D

Routers, layer 3 switches, some firewalls, and other gateways are packet filtering devices that use access control lists (ACLs) and perform packet inspection. This type of device uses a small subset of the packet to make filtering decisions, such as source and destination IP address and protocol. These devices will then allow or deny protocols based on their associated ports. This type of packet inspection and access control is still highly susceptible to malicious attacks, because payloads and other areas of the packet are not being inspected. For example, application level attacks that are tunneled over open ports such as HTTP (port 80) and HTTPS (port 443).

Question No. 5

An outside vulnerability assessment reveals that users have been routinely accessing Gmail from work for over a year, a clear violation of this organization's security policy. The users report ''it just started working one day''. Later, a network administrator admits he meant to unblock Gmail for just his own IP address, but he made a mistake in the firewall rule.

Which security control failed?

Show Answer Hide Answer
Correct Answer: C

Audits are used to identify irregular activity in logged (after-the-fact) records. If this activity went unnoticed or uncorrected for over a year, the internal audits failed because they were either incomplete or inaccurate.

Authentication, access control and managing user rights would not apply as a network admin could be expected to have the ability to configure firewall rules.
