The two chosen topics for this discussion are, the “Google Hacks” and “multi-factor authentication”. “Google Hacks” is a technique to gather information using the “Google” search engine. An attacker can use the “Google Hack” technique in a foolproof attack by intensifying the level of attack. The “Google Hack” helps an attacker to find out the specific software vulnerabilities or general misconfiguration of a system. The “Google Hacks” works better, when an attack is being planned based on the vulnerabilities of the system, rather than the system specific attacks (Rouse, n.d.).
