In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker). [1] [2] SQL injection must exploit a security vulnerability in an application's software, for example, when user ...
Code injection is the exploitation of a computer bug that is caused by processing invalid data. The injection is used by an attacker to introduce (or "inject") code into a vulnerable computer program and change the course of execution. The result of successful code injection can be disastrous, for example, by allowing computer viruses or ...
Security on the web depends on a variety of mechanisms, including an underlying concept of trust known as the same-origin policy.This states that if content from one site (such as https://mybank.example1.com) is granted permission to access resources (like cookies etc.) on a web browser, then content from any URL with the same (1) URI scheme (e.g. ftp, http, or https), (2) host name, and (3 ...
LDAP injection. In computer security, LDAP injection is a code injection technique used to exploit web applications which could reveal sensitive user information or modify information represented in the LDAP (Lightweight Directory Access Protocol) data stores. [1] [2] [3] LDAP injection exploits a security vulnerability in an application by ...
Stored procedure. A stored procedure (also termed prc, proc, storp, sproc, StoPro, StoredProc, StoreProc, sp, or SP) is a subroutine available to applications that access a relational database management system (RDBMS). Such procedures are stored in the database data dictionary . Uses for stored procedures include data-validation (integrated ...
Database activity monitoring (DAM, a.k.a. Enterprise database auditing and Real-time protection [1]) is a database security technology for monitoring and analyzing database activity. DAM may combine data from network-based monitoring and native audit information to provide a comprehensive picture of database activity.

A query plan (or query execution plan) is a sequence of steps used to access data in a SQL relational database management system. This is a specific case of the relational model concept of access plans. Since SQL is declarative, there are typically many alternative ways to execute a given query, with widely varying performance.
