Using Security Controls

Authentication

ID Requirement Code Example
AU001 The application shall use to TBD


Session Management

ID Requirement Code Example
AC001 The application shall use to TBD





Access Control

ID Requirement Code Example
AC001 The application shall use assertAuthorizedForURL() to verify authorization before allowing access to each URL. TBD
AC002 The application shall use assertAuthorizedForFunction() to verify authorization before allowing access to each business function. TBD
AC003 The application shall use assertAuthorizedForFile() to verify authorization before allowing access to files. TBD
AC004 The application shall use assertAuthorizedForData() to verify authorization before allowing access to data. TBD
AC005 The application shall use assertAuthorizedForService() to verify authorization before allowing access to each backend service. TBD
AC006 The application shall use isAuthorizedFor* methods to verify authorization before including user interface controls in HTML output. TBD
AC007 The application shall use AccessReferenceMap.getIndirectReference() to reference all application objects such as filenames, directory paths, and database keys. TBD
AC008 The application shall prevent access to all resources that should not be directly accessed by users (such as resources, XML files, JSP files, properties) by storing them in a protected directory, such as WEB-INF. TBD
AC009 The application shall use HTTPUtilities.sendSafeForward() for all forwards, to ensure that they cannot be used to bypass access checks. TBD
AC0010 The appplication must use only trusted data used in access control decisions. TBD
AC0011 Administrative functions for the application shall be deployed as a separate application with increased authentication controls. TBD



Input Validation and Encoding

ID Requirement Code Example
AC001 The application shall use to TBD



Data Protection

ID Requirement Code Example
AC001 The application shall use to TBD


| The application shall use an EncryptedProperties to store all security relevant data, such as passwords, credentials, codes, configuration information, addresses, etc…



Using Services Securely

ID Requirement Code Example
AC001 The application shall use to TBD



Error Handling

ID Requirement Code Example
AC001 The application shall use to TBD



Logging and Intrusion Detection

ID Requirement Code Example
AC001 The application shall use to TBD



Secure Configuration and Deployment

ID Requirement Code Example
SC001 Production code shall not contain code not intended for use, such as debug, test, and dead code. TBD
SC002 The application's source code shall not contain secrets that would compromise security if disclosed. TBD
SC003 The application team shall run code quality tools such as FindBugs and PMD to find quality problems. TBD



Avoiding Specific Risks

Cross Site Scripting

ID Requirement Code Example
AC001 The application shall use to TBD


Cross Site Request Forgery

ID Requirement Code Example
AC001 The application shall use to TBD


Thread Safety Problems

ID Requirement Code Example
AC001 The application shall avoid the use of shared storage, such as class variables, instance variables, or singletons, in all multithreaded code. TBD



Denial of Service

ID Requirement Code Example
AC001 The application shall use to TBD
