Security is a many-layered thing for most I.T. managers. Attacks may target network, server or application vulnerabilities. Blended threats combine multiple attack vectors Trojan horses, worms and viruses, for example in an attempt to outflank an organizations defenses.
In response, enterprises erect a series of barriers on the principle that an attack that beats one security measure wont get past other protections.
