Modern attacks against computer systems ask for a combination of multiple solutions in order to be prevented and detected. This paper will do the analysis of the capacities of commercial tools, with minimal configuration, to detect threats. Traditionally, companies use antivirus software to protect against malware, and a firewall combined with an IDS to protect against network attacks. This paper will analyze the efficacy of the following three combinations: antivirus, antivirus plus host IDS, and antivirus combined with a host IDS plus application whitelisting in order to withstand application attacks. Before doing the tests we predicted that the antivirus will block 20% of the attacks, the HIDS will detect an additional 15%, and McAfee Application Control will protect at least against 50% more of the attacks executed by an average attacker using known exploits, without much obfuscation of the payload. The success of defensive commercial tools against attacks will justify the investment a company will be required to make.
