The theory behind the Malware Threats Triangle is that there are three primary Internet security risks classified as Malware: Spam, Viruses, and Spyware. The characteristics of each primary risk combine to form secondary risks (blended threats).
Spam + Viruses = Worms
Spam + Spyware = Phishing/Adware
Viruses + Spyware = Trojans/Zombies
Each three risk grouping is handled by a solution.
Antispam
Spam
Worms
Phishing
Antivirus
Viruses
Worms
Trojans
Zombies
Antispyware
Spyware
Adware
Trojans
Although phishing scams and adware share the same components of a blended threat, they are in fact polar opposites. Phishing uses spam to gather information about the user. Adware uses gathered information to spam the user with advertisements.
That is what Antisource is all about. Antivirus, Antispam, and Antispyware. These are the security threats that network administrators must deal with on a regular basis.
