## AI Agent Security: Protecting Autonomous Systems

## The Shift: Answer-Bots to Action-Agents
* AI agents are evolving from passive tools to autonomous systems that browse websites, read emails, and execute actions.

## The New Attack Surface
* Agentic security models have a much larger attack surface than traditional models because they connect humans, multiple agents, tools, APIs, and databases.

## Leading Threats in AI
* **Prompt Injection**: The #1 attack vector where agents trust malicious instructions hidden in websites, PDFs, or chat messages.
* **Identity Spoofing**: Risks of agents being impersonated or tricked into unauthorized tasks.
* **Chain Attacks**: Compromising one agent can lead to a system-wide failure in multi-agent environments.
* **Adversarial Attacks**: Tiny pixel or data changes that cause massive perception mistakes in AI.

## Data Leakage and Tool Misuse
* Agents can accidentally expose passwords, API keys, medical records, or financial data.
* Connected tools can be weaponized (e.g., tricking an AI to delete repositories or transfer money).

## Real-World Consequences
* **Enterprise**: Employee impersonation and internal abuse.
* **Banking**: Fraudulent transactions and fake approval requests.
* **Healthcare**: Wrong diagnosis decisions and patient data leaks.

## Proposed Security Infrastructure
* **Agent Firewall**: Blocking injections before execution.
* **Identity Verification**: Secure authentication specifically for AI agents.
* **Monitoring Dashboards**: Auditing every decision and API call an agent makes.
* **Trust Scoring**: Dynamic risk assessment (e.g., Finance Agent = 95/100).
