Introduction to Database Encryption
Filed Under Data, Databases, Encryption, Security | Posted on September 12, 2009
Encryption can provide strong security for data, but is that enough ? Data in a database can be accessed by many systems, but developing a database encryption strategy must take many factors into consideration. Where should the encryption be performed, for example — in the database, or in the application where the data originates? Who [...]

Database Integrity is the preservation of data correctly & implies the process of keeping the dbase away from accidental deletion or alteration.
There are following types of integrity constraints:-
• Entity integrity constraints
• Referential integrity constraints
• Domain integrity constraints
DATABASE SECURITY: – Database security is a measurement of confidence that the integrity of a system and its data [...]
Overview of Database Security
Filed Under Databases, Security | Posted on September 11, 2009
Database security is the set of systems, processes, and procedures that protect a database from unintended activity. Unintended activity can be categorized as authenticated misuse, malicious attacks or inadvertent mistakes made by authorized individuals or processes. Database security is also a specialty within the broader discipline of computer security. The database is the entity where [...]

Computer networks are inherently insecure. To keep information secret, it must be encrypted. Encryption protocols fall into two general classes: secret key (e.g. DES, IDEA), and public key (e.g. RSA). Using these protocols is straight-forward; the hard part is key management.
In addition to providing secrecy, cryptographic protocols can also provide authentication. Finally, cryptography can also [...]
