Network Security Architecture

You serve as a Network Administrator for Net Perfect Inc. The company uses a TCP/IP-based network environment. The network includes a Cisco Catalyst router that connects the internal network to the Internet.

You want to protect the network from various attacks, including viruses, spam, spyware, phishing, and similar threats. You want to secure the entire network by using a separate hardware device. Which of the following would you use?

  • A PIX-Firewall
  • B IDS
  • C IPS
  • D ASA
Explanation

Cisco ASA is a dedicated network security appliance that combines stateful firewall capabilities with optional intrusion-prevention and content-security services. Supported content-security services can scan traffic to protect against viruses, spyware, spam, and other unwanted traffic, making ASA the broad hardware-based solution for protecting the whole network.
