In addition, surveys reveal that the impact of security incidents is far greater than those caused by outsiders (Baker et al., 2008 Vadera et al., 2008). EXPERIMENTATIONĮmployees are the second greatest cyber-security threat, exceeded only by hackers (Greitzer et al., 2008). Surveys confirm this and reveal that current or former 2.1 Materials 2. To be sure, this has always been true – thieving or otherwise corrupt workers have undoubtedly existed since commerce itself – but the power of computers (and the inability to secure them in the best of circumstances) makes the problem far worse today (Bellovin, 2008). Insiders are trusted and, therefore, have the necessary access to be able to exploit vulnerabilities more easily. International Journal of Scientific & Engineering Research, Volume 6, Issue 5, May-2015 1220Īnd Phyo, 2003). Organizations can suffer from direct effects of this threat, resulting in financial losses (Furnell Despite the likelihood of insider attacks and the potential magnitude of their impact, companies are still not doing enough to protect themselves against this kind of threat (Melara et al., 2003).
Although attacks originating from outside threat agents, such as hacking attempts or viruses, have gained a lot of publicity, the more risky attacks come from inside (Schultz, 2002). One of the problems with any logical breach of security is that the damage is invisible and its extent is unknown. Literature review reveals a stream of research on the cost of information systems security incidents.

A logical breach affects the data and software without physically affecting the hardware. A physical breach of security involves actual damage to or loss of the computer hardware or media on which data are stored. Computer security breaches can be grouped into physical and logical breaches. Precision in estimating computer security- related losses is not possible because many losses are never discovered, and others are “swept under the carpet”. Losses can stem, for example, from actions of supposedly trusted employees defrauding a system, from outside hackers, or careless data entry clerks. Almost every computer is challenged by more than one type of malicious attacks each day resulting in significant losses. INTRODUCTIONĬomputer users are facing all sort of security threats these days such as computer viruses, worms, Trojans, hacking, phishing, spyware etc. - University of Calabar Calabar – Nigeria 1. Keywords: Network Data, Malicious Activities, Communication Security, Computer Related Gadgets.
Technical risk management, vulnerability analysis and new threat research have all combined into a science. Organizations have learned the need for defensive measures against compromise of sensitive data and resources, such as virus defense, firewall, data encryption, logging, auditing, authorization, authentication and user education, to name a few. It is found that information in large corporate environment have made tremendous technical strides over the past years but as information becomes more available through the possession of computers and other computer related gadgets, attackers have discovered newer ways of breaking into our computer/network with the aim of gaining access to sensitive information, spreading viruses, worms, Trojan and inflicting distress through playful pranks. In this research a revision of large threats to communication security, effects on victims and ways of mitigating such threats have been carried out. It also offers opportunity to detect and understand a variety of phenomena that are related to overtly questionable or malicious activities on the part of the user’s and abusers. ABSTRACT: Routine acquisition and aggregation of network data offer an opportunity to understand some of the forces that drive the internet.
