Tresholds Governor, aims to facilitate the protection of authentication against brute force and dictionary attacks
INTRODUCTION
The OWASP Guide states "Applications MUST protect credentials from common authentication attacks as detailed
in the Testing Guide". This library aims to protect user credentials from
these authentication attacks. It is based on the "Tresholds Governer" described in the OWASP Guide.
FEATURES
-
Framework-independent library to be used from Framework-specific bundle/component or from applications that implement their own authentication
-
Registers authentication counts and decides to Block by username or client ip address for which authentication failed too often,
-
To hide weather an account actually exists for a username, any username that is tried too often may be blocked, regardless of the existence and status of an account with that username,
-
Facilitates a logical difference between failed login lockout and eventual administrative lockout, so that re-enabling all usernames en masse does not unlock administratively locked users (OWASP requirement).
-
Automatic release of username on authentication success (optional),
- Stores counters instead of individual requests to prevent database flooding from brute force attacks.
REQUIREMENTS
PHP >=5.3.3,
PDO or Doctrine DBAL ^2.3.4 or custom implementations of the Management interfaces.
Tested with MySQL 5.5. and SQLite 3
RELEASE NOTES
This is a pre-release version under development.
May be vurnerable to enumeration of usernames through timing attacks because of differences in database query performance for frequently and infrequently used usernames. This can be mitigated by calling ::sleepUntilFixedExecutionTime. Under normal circomstances that should be sufficient if the fixedExecutionSeconds is set long enough, but under high (database) server loads when performance degrades, under specific conditons information may still be extractable by timing.
