Security Agent Hardening

Security Agent Hardening

Overview

Cybersecurity skill for security agent hardening. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "Harden this agent against attacks"
• "Implement guardrails for autonomous agents"
• "Prevent prompt injection in my system"
• "Sandbox agent execution"
• "Audit agent security"
• "Secure LLM applications"

Use cases:

• Production AI agent deployment
• Customer-facing chatbots
• Autonomous code generation
• Multi-agent systems
• Tool-using agents (MCP, function calling)

When NOT to use:

• Internal research agents with no external input
• Fully human-in-the-loop systems
• Agents without tool access

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

Prerequisites

• Access to relevant log sources and security tools
• Understanding of agent hardening fundamentals
• Appropriate permissions for data access and tool operation

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}

1. Define Objectives — Clarify the goals and scope for agent hardening.
2. Gather Resources — Collect tools, data, and access needed for agent hardening.
3. Execute Process — Carry out agent hardening operations methodically.
4. Verify Quality — Check results against acceptance criteria.
5. Document Outcomes — Record findings, decisions, and next steps.

Tools

• Analysis Platform — Data processing and visualization
• Collaboration Tools — Team coordination and knowledge sharing

Process

1. Reconnaissance — Gather target information, identify attack surface, enumerate services
2. Analysis/Exploitation — Execute the technique, analyze results, document findings
3. Reporting — Document IOCs, write findings, provide remediation recommendations

Verification

• All agent hardening procedures executed completely and documented
• Findings validated against multiple data sources
• False positives identified and filtered
• Results documented with evidence and timestamps
• Recommendations provided with risk-based prioritization
