Virtual Appliance Deployment for Spam Filtering, Reverse Proxy, and Traffic Filtering | Exam N10-007

A small company has decided to use a single virtual appliance to filter spam as well as reverse proxy and filter traffic to its internal web server.

Which of the following has the company MOST likely deployed?

A.

IPS

B.

Firewall

C.

SIEM

D.

UTM

E.

Content filter.

E.

The company has deployed a single virtual appliance to filter spam, reverse proxy and filter traffic to its internal web server. The appliance that can perform all of these functions is called a Unified Threat Management (UTM) appliance.

A UTM appliance is a network security device that integrates multiple security features such as firewall, intrusion detection/prevention, antivirus, content filtering, VPN and more into a single device, making it easy to manage and administer.

In this scenario, the UTM appliance is being used for spam filtering, reverse proxying, and filtering traffic to the internal web server. Spam filtering involves the inspection of incoming emails to identify and discard any unwanted or malicious emails. Reverse proxying is a technique that involves using a proxy server to handle requests from clients to servers. This can help to protect the web server from direct access by the clients, thus enhancing security. Filtering traffic to the internal web server involves monitoring and controlling the flow of traffic to the web server to prevent unauthorized access or attacks.

The other options listed in the question are:

• IPS (Intrusion Prevention System) is a network security device that monitors network traffic for signs of known attacks and takes immediate action to prevent them.
• Firewall is a network security device that monitors and controls traffic entering and leaving a network.
• SIEM (Security Information and Event Management) is a software solution that aggregates and analyzes security event data from various sources to detect and respond to security incidents.
• Content filter is a network security device that filters and controls access to web content based on predefined policies.

None of these options would be capable of performing all the functions required in this scenario. Only a UTM appliance is designed to integrate multiple security features into a single device, making it the most likely solution that the company has deployed.
