A security threat usually takes a toll on the databases of the companies, leading to significant financial losses and confidential information leakage. Data breaches is one of the most common problems experienced by the companies. Last year, 83% of organisations suffered a data security incident, clearly accounting for the major vulnerability of the security systems to cyber mishaps. The threats can be caused by both internal or external forces. According to Steve Durbin, managing director of the Information Security Forum (ISF), there are three categories of insider behaviour : “Malicious, Negligent and Accidental”. An internal security threat is caused when in a corporate environment the employees are not able to understand security related issues leading to negligent leakage of data, while sometimes it can be intentional. An External threat, on the other hand, originates from outside the company and can come from criminal syndicates, state-sponsored actors and hacktivists.
