A basic cornerstone of security is to verify the integrity of fundamental data stored in the system. This integrity checking is being achieved using integrity tools such Tripwire, which depend on the integrity and proper operation of the operating system, i.e. these applications assume that the operating system always operates correctly. When this assumption is [...]

In highly networked modern world, conventional techniques of network security such as user authentication, cryptography and intrusion prevention techniques like firewalls are not enough, owing to formulations of new attacks. Intrusion detection systems are becoming an important need for today’s networks. Anomaly detection is used as a part of intrusion detection systems, which in turn [...]

Reliable user authentication is becoming an increasingly important task in the Web-enabled world. The consequences of an insecure authentication system in a corporate or enterprise environment can be catastrophic, and may include loss of confidential information, denial of service, and compromised data integrity. The value of reliable user authentication is not limited to just computer [...]

Explosive growth in data storing and data processing technologies has led to the creation of large databases that record unprecedented amount of information. Consequently, with the increase in data storage and processing, concerns about information privacy have emerged. Data mining, with its promise to efficiently discover valuable non-obvious information from large databases, is particularly sensitive [...]

The importance of databases in modern businesses and governmental institutions is huge and still growing. Many mission-critical applications and business processes rely on databases.
