One technique for evaluating database security involves performing vulnerability assessments or penetration tests against the database. Testers attempt to find security vulnerabilities that could be used to defeat or bypass security controls, break into the database, compromise the system etc. Database administrators or information security administrators may for example use automated ...
Software-based security solutions encrypt the data to protect it from theft. However, a malicious program or a hacker could corrupt the data to make it unrecoverable, making the system unusable. Hardware-based security solutions prevent read and write access to data, which provides very strong protection against tampering and unauthorized access.
In this matrix example there exist two processes, two assets, a file, and a device. The first process is the owner of asset 1, has the ability to execute asset 2, read the file, and write some information to the device, while the second process is the owner of asset 2 and can read asset 1.
Encryption can be employed to enhance the security of data stored in a database by converting the information into an unreadable format using an algorithm. The encrypted data can only be accessed and deciphered with a decryption key, ensuring that even if the database is compromised, the information remains confidential.
The first single-database computational PIR scheme to achieve communication complexity less than was created in 1997 by Kushilevitz and Ostrovsky [3] and achieved communication complexity of for any , where is the number of bits in the database. The security of their scheme was based on the well-studied Quadratic residuosity problem.
The standard requires effective security measures that protect sensitive (personal) data and other assets, such as command and control data. It also requires that security vulnerabilities in the software have been eliminated, security principles, such as defense-in-depth have been followed, and the security of the software has been verified ...

Internet security is a branch of computer security. It encompasses the Internet, browser security, web site security, [1] and network security as it applies to other applications or operating systems as a whole. Its objective is to establish rules and measures to use against attacks over the Internet. [2]
