Image:Asvs-letters.jpgESAPI Terminology

  • adapter - There are optionally your own implementations for each security control. There may be application logic contained in these classes which may be developed by or for your organization. The logic may be organization-specific and/or application-specific. There may be proprietary information or logic contained in these classes which may be developed by or for your organization.
  • built-in singleton design pattern - The "built-in" singleton design pattern refers to the replacement of security control reference implementations with your own implementations. ESAPI interfaces are otherwise left intact.
  • codec - ESAPI encoder/decoder reference implementations.
  • core - The ESAPI interfaces and reference implementations that are not intended to be replaced with enterprise-specific versions are called the ESAPI Core.
  • exception - ESAPI exception reference implementations.
  • extended factory design pattern - The "extended" factory design pattern refers to the addition of a new security control interface and corresponding implementation, which in turn calls ESAPI security control reference implementations and/or security control reference implementations that were replaced with your own implementations. The ESAPI locator class would be called in order to retrieve a singleton instance of your new security control, which in turn would call ESAPI security control reference implementations and/or security control reference implementations that were replaced with your own implementations.
  • extended singleton design pattern - The "extended" singleton pattern refers to the replacement of security control reference implementations with your own implementations and the addition/modification/subtraction of corresponding security control interfaces.
  • ES-enable (or ESAPI-enable) - Just as web applications and web services can be Public Key Infrastructure (PKI) enabled (PK-enabled) to perform for example certificate-based authentication, applications and services can be OWASP ESAPI-enabled (ES-enabled) to enable applications and services to protect themselves from attackers.
  • filter - In ESAPI for Java, there is additionally an HTTP filter that can be called separately from the other controls.
  • interfaces - There is a set of security control interfaces. There is no application logic contained in these interfaces. They define for example types of parameters that are passed to types of security controls. There is no proprietary information or logic contained in these interfaces.
  • locator - The ESAPI security control interfaces include an "ESAPI" class that is commonly referred to as a "locator" class. The ESAPI locator class is called in order to retrieve singleton instances of individual security controls, which are then called in order to perform security checks (such as performing an access control check) or that result in security effects (such as generating an audit record).
  • reference implementation - There is a reference implementation for each security control. There is application logic contained in these classes, i.e. contained in these interface implementations. However, the logic is not organization-specific and the logic is not application-specific. There is no proprietary information or logic contained in these reference implementation classes.
  • Web Application Firewall (WAF) - In ESAPI for Java, there is additionally a Web Application Firewall (WAF) that can be called separately from the other controls.
