What is a database security?

Database security is a number of methods used to protect information stored in the database. While hackering attempts are most often the idea of ​​information about database information, there are many other dangers. Physical damage to the computer, incorrect coding or corruption and data overload are all potential database threats. This means that there are usually many security measures - from the firewall to audit and backup discs - to maintain possible minimum damage and prevent the entire database from losing. Most companies have their own database security protocols that protect against specific attacks and potential damage. Firewally are installed on most computers and are made so hackers have a difficult time to connect to the victim's computer. Firewally works by filtering through a network connection and only allow trusted computers or users to access the database. While it can bypass qualified hackers, the firewall provides high levelsSecurity.

Encryption is another database security rate in which data is encrypted or unreadable for anyone who approaches the database. When using encryption, the algorithm plucks characters into nonsense, so it can't be read. This means that if a hacker does not have a specific knowledge of the encryption key, information that one has to change encrypted data from illegible characters back to readable format, there is no way to read the database.

Auditing is when a supervisor or database manager scans the database to ensure that nothing has changed. This type of database security can be performed physically, someone who reads the database, or using a program for larger databases to see if Coding is the same. Auditing may also include control of access to the database and see what employees did when they approached the database. This prevents data theft or at least allows administrators to find outwho committed data theft.

Database backup is a database security rate that protects from many different threats. When the database is backed up, it means that the data is stored in another area or medium. If the database loses any or all information, it can be restarted immediately with a minimum backup loss. By making a backup of the database, administrators are able to protect against physical damage to the computer, such as fire, database corruption or database that turns off overload.
