Question

What is the most effective control for restricting access to unauthorized internet sites in an organization?

1) Firewall
2) Antivirus software
3) Content filtering
4) Intrusion detection system

Answer 1

Content filtering is the most effective control for restricting access to unauthorized internet sites in an organization. Option 3 is correct .

Step-by-step explanation:

The most effective control for restricting access to unauthorized internet sites in an organization is content filtering. Content filtering is a technique used to prevent users from accessing certain websites based on predefined criteria. This control works by examining website URLs or the content of webpages and blocking access to websites that don't meet the specified criteria.

For example, an organization may want to restrict access to gambling and adult content websites. Content filtering software can be configured to block access to these types of sites, while allowing access to other websites for research or communication purposes.

Firewalls and intrusion detection systems also play important roles in network security, but their main functions are not specifically targeted at restricting access to unauthorized internet sites. Therefore, Option 3 is correct.
