In this paper we propose four architectures for intrusion-tolerant database systems. While
traditional secure database systems rely on prevention controls, an intrusion-tolerant …

The immaturity of current intrusion detection techniques limits the traditional security systems
in surviving malicious attacks. Intrusion tolerance approaches have emerged to overcome …

Security models, developed for databases, differ in many aspects because they focus on
different features of the database security problem or because they make different …

One of the main problems faced by organizations is the protection of their data against
unauthorized access or corruption due to malicious actions. Database management systems …

Databases are the repositories of the most important and expensive information in the
enterprise. With the increase in access to data stored in databases, the frequency of attacks …

A trusted computer system is designed to be'secure'with respect to some well-defined
security policy. There are two major classes of information security policy:(1) secrecy …

In this paper, we present the design and implementation of ITDB, a self-healing or intrusion-
tolerant database prototype system. While traditional secure database systems rely on …

Intrusion detection (ID) has become an important technology for protecting information
resources and databases from malicious attacks and information leakage. This paper …

System protection mechanisms such as access controls can be fooled by authorized but
malicious users, masqueraders, and misfeasors. Intrusion detection techniques are …

Although there are several choices of policies for protection of information, access control
models have been developed for a fixed set pre-defined access control policies that are then …
