Firewall

A Chief Information Officer (CIO) tasks the network engineer with protecting the network from outside attacks.

Placing which of the following devices on the network perimeter would provide the MOST security for the system?

A.

Firewall

B.

NGFW

C.

Content filter

D.

IDS/IPS.

B.

The device that would provide the most security for a network perimeter against outside attacks is a Next-Generation Firewall (NGFW), option B.

A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted, secure internal network and an untrusted, external network such as the internet.

A NGFW, on the other hand, is an advanced version of a traditional firewall that includes additional security features such as deep packet inspection, intrusion prevention, and application awareness. NGFWs use a combination of traditional firewall features and advanced security technologies to provide enhanced security against modern-day cyber attacks.

A content filter is a security device that is designed to filter out specific types of web content based on a predefined set of rules. While content filters can be helpful in preventing access to potentially harmful websites or content, they are not specifically designed to protect against outside attacks on a network perimeter.

An IDS/IPS (Intrusion Detection/Prevention System) is a network security appliance that monitors network traffic for signs of unauthorized access or malicious activity. While they are effective at detecting and preventing network intrusions, they are not specifically designed to protect against outside attacks on a network perimeter.

In summary, a NGFW would provide the most security for a network perimeter against outside attacks. It combines traditional firewall features with advanced security technologies to provide enhanced protection against modern-day cyber threats.
