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. Code injections are a class of computer security exploits in which a vulnerable computer program misinterprets external data (usually user input) as part of its programming. An attacker utilizing this method thereby "injects" code into the program while it is running, changing the course of its execution.
Cross-site request forgery is an example of a confused deputy attack against a web browser because the web browser is tricked into submitting a forged request by a less privileged attacker. CSRF commonly has the following characteristics: It involves sites that rely on a user's identity. It exploits the site's trust in that identity.
Database activity monitoring. 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.
The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Edgar F. Codd [12] in the early 1970s. [13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...
Cross-site leaks, also known as XS-leaks, is an internet security term used to describe a class of attacks used to access a user's sensitive information on another website. Cross-site leaks allow an attacker to access a user's interactions with other websites. This can contain sensitive information. Web browsers normally stop other websites ...
A simple example is the following malicious version of the Linux sudo command. An attacker would place this script in a publicly writable directory (e.g., /tmp). If an administrator happens to be in this directory and executes sudo, then the Trojan may execute, compromising the administrator's password.
