Attacks against computer networks are becoming more sophisticated, with adversaries using new attacks or modifying existing attacks. With increased global interconnectivity, reliance on e-commerce, network services, and Internet communication, computer security has become a necessity. Organizations must protect their systems from intrusion and computer-virus attacks. Such protection must detect...

Interconnectivity on the Internet is growing, as more and more organizations, private companies and governmental institutions connect for critical information processing. This interconnectivity allows for better productivity, faster communication capabilities and immeasurable personal conveniences. It also opens the door to many unforeseeable risks, such as individuals gaining unauthorized acce...

In recent years database security has become one of the major issues in computer security. Database security is concerned with preventing unauthorized and malicious access into a database. A number of mechanisms needed to defend information, such as verification, user privileges, data encryption, and auditing, are available in DBMS. In reality, malicious access of databases by unauthorized user...

Thirty years ago, Congress passed the Computer Fraud and Abuse Act ("CFAA ") to combat the emerging problem of computer crime. The statute's core prohibitions targeted one who "accesses" a computer "without authorization" or who "exceeds authorized access."

Journal of Networking Technology Volume 5 Number 3 September 2014 ABSTRACT: In recent years, wireless access technology is quite popular for its convenience, fast and flexible. However, due to the openness of wireless network, this technology also faces with a number of secure challenges, one of which is how to deal with the unauthorized access point effectively. As we all know, the unauthorize...

One of the main requirements for providing software security is the enforcement of access control policies which aim to protect resources of the system against unauthorized accesses. Any error in the implementation of such policies may lead to undesirable outcomes. For testing the implementation of access control policies, it is preferred to use automated methods which are faster and more relia...
