CYBERWARFARE

In terms of action cyber warfare usually occurs when individuals take it upon them elves to abuse computers, electronics and technological devices in a desperate attempt and also with the intention of  to gain access and hack into the oppositions information system.

Cyber warfare corresponds well with information warfare as they can somehow relate to each other for instance information warfare is the transportation of communication through the usage of electronics and the internet to suspend. Telecommunication, power supply and transport in a particular region.

With regards to modern day social media and networking I would say that, in recent years popular social networking sites such as facebook and twitter have gained a lot of users as it is one of many diverse ways in which distant, close, and long lost friends, associates, family etc can keep in touch all because of the use of technology and the internet. With that being said I would also add that when starting up facebook/twitter etc you share a lot of personal information about yourself which automatically gets saved on to the facebook database and is available to be viewed by many.

This makes social media and networking an easy target for hacking which is considered as cyber warfare in view of the fact that it is common knowledge that a lot of private/ personal information, pictures messages are all being distributed through facebook so therefore hackers will gain a lot of informative profiles on individuals by just abusing and hacking there account.

Cyber warfare is Internet-based conflict involving politically motivated attacks on information and information systems. Cyber warfare attacks can disable official websites and networks, disrupt or disable essential services, steal or alter classified data, and cripple financial systems -- among many other possibilities.
