Denny wants to deploy antivirus for his organization and wants to ensure that it will stop the most malware. What deployment model should Denny select?
Answer Options
Install antivirus from the same vendor on individual PCs and servers to best balance visibility, support, and security.
Install antivirus from more than one vendor on all PCs and servers to maximize coverage.
Install antivirus from one vendor on PCs and from another vendor on the server to provide a greater chance of catching malware.
Install antivirus only on workstations to avoid potential issues with server performance.
Correct Answer: C
Explanation
In this scenario, Denny specifically needs to ensure that he stops the most malware. In situations like this, vendor diversity is the best way to detect more malware, and installing a different vendor’s antivirus (AV) package on servers like email servers and then installing a managed package for PCs will result in the most detections in almost all cases. Installing more than one AV package on the same system is rarely recommended, since this often causes performance issues and conflicts between the packages—in fact, at times AV packages have been known to detect other AV packages because of the deep hooks they place into the operating system to detect malicious activity!
