4. Hack Attack

Intrusion and interception is not an alien to any paradigm of communication. Computers, business machines and cell phone networks, everything has been attacked by hackers already. Apple, which had always been certain about its imperceptible security, also faced reality when recently more than 600,000 Apple computers were infected with the Flashback Trojan. An average hacker earns about $1,000 to $5,000 per day and a single attack can cause an equivalent loss to an individual victim, reports Digg. Hence it is strongly recommended to have effective security tools installed on the devices which are used over the network.
