Question 57

Content filter is the best solution for blocking inappropriate websites and logging access attempts.

A content filter effectively blocks access to inappropriate websites by categorizing and restricting content based on predefined criteria. It also logs access attempts, providing the management team with the necessary records to monitor and enforce internet usage policies.

A) Content filter

A content filter directly addresses the requirements of blocking inappropriate websites and maintaining a log of access attempts. It utilizes URL filtering and keyword detection to prevent users from visiting specified sites while simultaneously recording each attempt in a log for review.

B) Screened subnet

A screened subnet serves as a security layer within a network by isolating certain devices, but it does not inherently block access to specific websites or log individual user attempts. Its primary function is to enhance network security rather than manage web content access.

C) Port forwarding

Port forwarding is a technique used to direct incoming traffic from the internet to specific devices within a private network. While it can control traffic flow, it does not provide capabilities for filtering web content or logging access to websites, making it unsuitable for the requirements stated.

D) Access control list

An access control list (ACL) can restrict access to certain resources but is typically used for managing permissions within a network rather than filtering web content. It does not provide the functionality needed to log web access attempts or block inappropriate websites effectively.

Conclusion

The content filter is the only option that fulfills both requirements of blocking inappropriate websites and logging access attempts. Other options, such as screened subnets, port forwarding, and access control lists, do not provide the necessary web content filtering or logging capabilities, making them ineffective in this scenario.
