What are the levels of database security in information security?
Data security defines the process of protecting data from unauthorized access and data corruption throughout its lifecycle. Data security involves data encryption, hashing, tokenization, and key administration practices that secure data across some applications and platforms.
Security database professionals have to depend on network management for implementing firewalls or other structure to defend local information as the nature of Intranet/Internet data access is though the database administrator (DBA) has to carry out some security function. This unit will scrutinize the fundamental security areas that fall within the area of the DBA, who then has to create database familiarized solutions.
The security of database management systems is based on multiple systems. These chiefly include the operating system, the applications that need the DBMS, services that interrelate with the DBMS, the internet server that creates the application obtainable to end users, etc.
There are various levels of database security which are as follows −
Server Security − Server security involves limiting access to data accumulated on the server. It is the essential choice that has to be taken in deliberation and planned sceptically.
Database Connections − By means of the ODBC will have to be followed by curious that each connection corresponds to a specific user who has access to data. Database contact should be confined to machines that have to converse to it while assuring standard protection are in position.
Also, if a company accesses an internet application to use its database with such scripts in Active Server Page, or ASP.NET technology and the scripts crash, it can possibly reveal its source program when it creates an error report.
In this case, limiting database access to the accurate users is important. If through appropriate security gauges the database access is defined to the true users, any script crashes will not reveal database connection data to the erroneous users.
This takes place more than a few times including the database connection name and password for all the world to consider. It is endorsed to change the password for the database connection on a traditional basis, which insert only one more layer of security to the process.
Table Access Control − The access control table is the common type of securing a database. A proper use of the table access control contains a close association between the management and the base developer.
Restricting Database Access − There are situations when access to a definite database should be defined to some assured users. The NCSA http server has integrated user authentication traits that can be easily adapted to function with an online database.
