All Database Management Systems used in the industry provide secure access to data at the server level. The level of security is influenced by technology, security model, password encryption method, password strength and others. The human factor – unreasonable behaviour of users – also has a significant impact on safety. Developers of database applications often implement their security policy by limiting the risk caused by users. This implementation has a disadvantage – it does not work outside of the application. A large number and variety of applications that work with the database server may then create a security gap. The paper presents the authors’ extensions of the functional features implemented in the Oracle database server, increasing the security of data access. The implemented methods of controlling the time of user access to data and limiting the use of serial and modular passwords are also discussed.
