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 ...
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 ...
An SQL injection takes advantage of SQL syntax to inject malicious commands that can read or modify a database, or compromise the meaning of the original query. [13] For example, consider a web page that has two fields to allow users to enter a username and a password.
Cross-site scripting. Cross-site scripting (XSS) is a type of security vulnerability that can be found in some web applications. XSS attacks enable attackers to inject client-side scripts into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same-origin policy.
In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system. A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [2] Another type of approach is password spraying, which ...
e. Digest access authentication is one of the agreed-upon methods a web server can use to negotiate credentials, such as username or password, with a user's web browser. This can be used to confirm the identity of a user before sending sensitive information, such as online banking transaction history.
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 ...
Illustration of a replay attack. Alice (A) sends her hashed password to Bob (B). Eve (E) sniffs the hash and replays it. Suppose Alice wants to prove her identity to Bob. . Bob requests her password as proof of identity, which Alice dutifully provides (possibly after some transformation like hashing, or even salting, the password); meanwhile, Eve is eavesdropping on the conversation and keeps ...
