    en.wikipedia.org/wiki/SQL_injection

    Blind SQL injection is used when a web application is vulnerable to a SQL injection, but the results of the injection are not visible to the attacker. The page with the vulnerability may not be one that displays data but will display differently depending on the results of a logical statement injected into the legitimate SQL statement called ...

    If any of these variables is used to execute dangerous commands (such as direct commands to a SQL database or the host computer operating system), the taint checker warns that the program is using a potentially dangerous tainted variable. The computer programmer can then redesign the program to erect a safe wall around the dangerous input.

    Time-of-check vs time-of-use can be classified as architectural flaws. Parsing and validation. SQL injection attacks and cross-site scripting fall into this category. Memory safety. In memory-unsafe programming languages, lower-level issues such as buffer overflows and race conditions can be exploited to take partial or complete control of the ...

  6. Static application security testing - Wikipedia

    The earlier a vulnerability is fixed in the SDLC, the cheaper it is to fix. Costs to fix in development are 10 times lower than in testing, and 100 times lower than in production. [18] SAST tools run automatically, either at the code level or application-level and do not require interaction.

  7. Database activity monitoring - Wikipedia

    en.wikipedia.org/wiki/Database_activity_monitoring

    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 ...

  8. Web application firewall - Wikipedia

    en.wikipedia.org/wiki/Web_application_firewall

    A web application firewall (WAF) is a specific form of application firewall that filters, monitors, and blocks HTTP traffic to and from a web service.By inspecting HTTP traffic, it can prevent attacks exploiting a web application's known vulnerabilities, such as SQL injection, cross-site scripting (XSS), file inclusion, and improper system configuration. [1]

  9. Vulnerability database - Wikipedia

    en.wikipedia.org/wiki/Vulnerability_database

    A vulnerability database (VDB) is a platform aimed at collecting, maintaining, and disseminating information about discovered computer security vulnerabilities.The database will customarily describe the identified vulnerability, assess the potential impact on affected systems, and any workarounds or updates to mitigate the issue.
