www-project-agent-memory-guard vs rsigma

www-project-agent-memory-guard: OWASP Agent Memory Guard is a runtime defense solution designed to prevent AI agents from being weaponized through their own memory by detecting and blocking memory poisoning attacks. It provides a robust security layer that intercepts malicious writes to agent memory, ensuring the integrity and safety of AI operations even after context resets.; rsigma: RSigma is a comprehensive detection engineering toolkit for the Sigma detection standard, offering a parser, evaluation engine, rule conversion, streaming runtime, linter, CLI, MCP, and LSP. It processes Sigma YAML rules into a strongly-typed AST, compiles them into optimized matchers, and evaluates them against log events in real time, featuring in-process stateful correlation logic.

Features

www-project-agent-memory-guard logowww-project-agent-memory-guard
01Integrity: SHA-256 baselines flag out-of-band tampering with immutable keys.
02Threat detection: Built-in detectors for prompt injection, sensitive data leakage, protected-key modifications, size anomalies, and self-reinforcement loops.
03Policy enforcement: YAML-defined rules map findings to actions like `allow`, `redact`, `quarantine`, or `block`.
04Forensics: Every decision emits a structured `SecurityEvent`, with point-in-time snapshots for rollback to a known-good state.
05Drop-in middleware: Ships with `GuardedChatMessageHistory` for LangChain and general framework-agnostic `MemoryStore` protocol.
rsigma logorsigma
01Real-time Sigma rule parsing and evaluation with in-process stateful correlation logic.
02Built-in linter, LSP server, and MCP server for comprehensive rule authoring and AI agent integration.
03Flexible log ingestion (JSON, OTLP, EVTX, syslog) and extensible alert delivery (webhooks, NATS, OTLP).
04Rule conversion to backend-native queries and advanced detection engineering metrics (ATT&CK coverage, scorecard).
