With the increased use of information systems on a global level, security threats have never been so prevalent. The increasing trend of using information systems on a day to day basis has therefore led to the development of ways of protecting the valuable information held in these systems.
Today, information systems are vulnerable to new threats such as viruses that circulate through the internet. It has been stated that a security breakdown in a firm can result in severe problems. “ a recent survey on 1,000 UK organizations shows that the occurrence of a security failure in a business with no contingency plan leads to its shutdown in 80% of the cases, and 60% of UK businesses have suffered an important security breach in the last two years.” This fact highlights the developing threats to information systems and their ability to ruin organisations.
Social media sites in particular have been at risk of being targeted by attackers. For example, last year twitter users were led to believe they had been tagged in a video, once they clicked on the link they were transferred to a website that advised the user to update their youtube player in order to view the video. If the user continued to download the new version of the youtube player their computers would be infected with a form of a trogan. These trogans are a form of malware which facilitates the unauthorized access to the users’ computer system and allows the attacker to steal information held in the users account.
