A classification of SQL injection attacking vector as of 2010. 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).
Injection exploits are computer exploits that use some input or data entry feature to introduce some kind of data or code that subverts the intended operation of the system. Usually these exploits exploit vulnerabilities resulting from insufficient data validation on input and so forth.
An example of how you can see code injection first-hand is to use your browser's developer tools. Code injection vulnerabilities are recorded by the National Institute of Standards and Technology (NIST) in the National Vulnerability Database as CWE-94. Code injection peaked in 2008 at 5.66% as a percentage of all recorded vulnerabilities. [4]
The database system can ensure data integrity and consistency with the help of stored procedures. Delegating access-rights In many systems, stored procedures can be granted access rights to the database that users who execute those procedures do not directly have. Some protection from SQL injection attacks
Layer 2 attacks: This type of attack exploit the vulnerabilities of data link layer protocols and their implementations on layer 2 switching platforms. SQL injection : Also known as code injection, this is where input to a data-entry form's, due to incomplete data validation, allows entering harmful input that causes harmful instructions to be ...
Improper input validation [1] or unchecked user input is a type of vulnerability in computer software that may be used for security exploits. [2] This vulnerability is caused when "[t]he product does not validate or incorrectly validates input that can affect the control flow or data flow of a program." [1] Examples include: Buffer overflow
The technique transforms an application SQL statement from an innocent SQL call to a malicious call that can cause unauthorized access, deletion of data, or theft of information. [ 3 ] One way that DAM can prevent SQL injection is by monitoring the application activity, generating a baseline of “normal behavior”, and identifying an attack ...
An example of a data-integrity mechanism is the parent-and-child relationship of related records. If a parent record owns one or more related child records all of the referential integrity processes are handled by the database itself, which automatically ensures the accuracy and integrity of the data so that no child record can exist without a parent (also called being orphaned) and that no ...
