Column level encryption is a type of database encryption method that allows user to select specific information or attributes to be encrypted instead of encrypting the entire database file. To understand why column level encryption is different from other encryption methods like file level encryption , disk encryption , and database encryption ...
A typical relational database is divided into tables that are divided into columns that each have rows of data. [10] Whilst TDE usually encrypts an entire database, column-level encryption allows for individual columns within a database to be encrypted. [11]
Cryptography can be implemented on the database housing the data and on the physical storage where the databases are stored. Data encryption keys should be updated on a regular basis. Encryption keys should be stored separately from the data. Encryption also enables crypto-shredding at the end of the data or hardware lifecycle. Periodic ...
In the context of SQL, data definition or data description language (DDL) is a syntax for creating and modifying database objects such as tables, indices, and users. DDL statements are similar to a computer programming language for defining data structures, especially database schemas. Common examples of DDL statements include CREATE, ALTER ...
The SQL/Schemata, or Information and Definition Schemas, part of the SQL standard is defined by ISO/IEC 9075-11:2008. SQL/Schemata defines the information schema and definition schema , providing a common set of tools to make SQL databases and objects self-describing.
SQL:2011 or ISO/IEC 9075:2011 (under the general title "Information technology – Database languages – SQL") is the seventh revision of the ISO (1987) and ANSI (1986) standard for the SQL database query language. It was formally adopted in December 2011. [1] The standard consists of 9 parts which are described in detail in SQL.
Database objects may include table or other objects listed in the Table link. The permissions granted for SQL language commands on objects are considered in this process. Compliance monitoring is similar to vulnerability assessment, except that the results of vulnerability assessments generally drive the security standards that lead to the ...
The Database Master Key is used in conjunction with a certificate to encrypt the Database Encryption Key. The Database Encryption Key is used to encrypt the underlying database files with either the AES or 3DES cipher. The master database that contains various system level information, user accounts and management services is not encrypted ...
