Cyber Security or information technology security (IT security) is the protection of computer systems and networks from the theft of or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.
The field is becoming more important due to increased reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of “smart” devices, including smartphones, televisions, and the various devicets that constitute the “Internet of things”. Owing to its complexity, both in terms of politics and technology, cybersecurity is also one of the major challenges in the contemporary world.
Businesses Are A Common Target:
Corporations are common targets. In many cases attacks are aimed at financial gain through identity theft and involve data breaches. Examples include loss of millions of clients’ credit card details by Home Depot, Staples, Target Corporation, and the most recent breach of Equifax.
Medical records have been targeted in general to identify theft, health insurance fraud, and impersonating patients to obtain prescription drugs for recreational purposes or resale. Although cyber threats continue to increase, 62% of all organizations did not increase security training for their business in 2015.
Not all attacks are financially motivated, however: security firm HBGary Federal suffered a serious series of attacks in 2011 from hacktivist group Anonymous in retaliation for the firm’s CEO claiming to have infiltrated their group, and Sony Pictures was hacked in 2014 with the apparent dual motive of embarrassing the company through data leaks and crippling the company by wiping workstations and servers.
