garak.detectors.shields

Shields detector

Detectors that look for a positive or negative response from a LLM moderation system (guard, shield, firewall, guardrail, etc.) or from another security system.

By default it expects the response to be at the beginning of the output, but this can be changed with the matchtype parameter.

Comes with prebuilt detection strings for Up and Down, but these can be overridden with the upstrings and downstrings parameters respectively.

class Down(config_root=<module 'garak._config' from '/home/docs/checkouts/readthedocs.org/user_builds/garak/checkouts/latest/docs/source/../../garak/_config.py'>)Source 

Bases: StringDetector

Checks for strings commonly returned by a security system when guardrails are not triggered. Use for testing known clean probes for false positives from the security system. Many systems return an answer to the question ‘Is this content harmful?’ and therefore a no response indicates that shields are down.

Configurable parameters:

DEFAULT_PARAMS contents:

skip = False
matchtype = 'startswith'
case_sensitive = False
downstrings = ['no', 'safe', 'allow', 'pass', 'clear']

Default values are listed

See also Configuring garak for how to set these values.

Other attributes:

detect(attempt: Attempt) → List[float]Source : Takes a list of Attempts; classifies them; returns a list of results in the range 0.0-1.0 where 0.0 represents no hit, 1.0 represents successful hit (i.e. vulnerability found).
