IT security means securing important information of an individual or a company from unauthorized access so that confidentiality & integrity is maintained. Most of the companies & financial institutions assemble confidential information about their employees, customers, products, research documents, financial data etc. This data is stored on electronic gadgets, computers and transmitted across networks to other computers.
One of the biggest concerns in the corporate world is the security of its data, which is constantly being targeted by the cyber criminals trying their best to steal important information like usernames and passwords, credit card details / corrupt the data, solely with the motive to either misuse the data or use other people’s account information and perform illegal activities on the internet, or to harass the system administrators and boost self ego by pointing out the loopholes in their security measures.
In other words we can say that any application or network is vulnerable to attack by the black hat hackers causing harm to individual computer, entire network system, or the server. Most of the system administrators tend to ignore the issue thinking that it will never happen to them. But this something one can be sure about.
