AWS re:Invent 2025 -Multi-Agent Collaboration w/ Amazon Bedrock Agentcore for Advanced SecOps-NTA407

Multi-Agent Collaboration for Advanced SecOps with Amazon Bedrock Agentcore

Overview

• The presentation discusses leveraging multi-agent collaboration using Amazon Bedrock Agentcore to automate and streamline security operations (SecOps) workflows.
• The key challenges addressed are the repetitive, manual tasks involved in security alert investigation, remediation, and reporting that security teams often face.

Security Operations Workflow

• The typical security operations workflow consists of three main steps:
  1. Investigation: Analyze the security alert to understand the impact and affected resources.
  2. Remediation: Implement a tactical fix to address the immediate issue, as well as a long-term solution to prevent recurrence.
  3. Reporting: Summarize the incident, actions taken, and outcomes in a comprehensive report.
• These steps are often repetitive and time-consuming for security teams, motivating the need for automation.

Amazon Bedrock Agentcore Platform

• Amazon Bedrock Agentcore is a fully managed platform that enables building, deploying, and running multi-agent solutions in a secure manner.
• Key components of the Bedrock Agentcore platform:
  • Agent Runtime: Allows building agents using various frameworks like LangChain, LangFuse, and AWS Transfomer SDK.
  • Agent Gateway: Provides an interface for agents to connect to internal systems and tools, such as configuration management databases (CMDB) and playbook repositories.
  • Agent Identity: Manages authentication and authorization for agents to access internal resources.
  • Agent Observability: Tracks and logs the actions performed by agents.

Multi-Agent Architecture for Security Operations

• The proposed architecture leverages three specialized agents within the Bedrock Agentcore platform:
  1. Investigation Agent: Gathers details about the security alert, such as affected resources, software versions, and patching schedules, by integrating with the CMDB.
  2. Remediation Agents:
     • Containment Helper Agent: Prepares a remediation playbook for the security operator to follow.
     • Containment Actor Agent: Automatically executes the remediation playbook to address the issue.
  3. Reporting Agent: Generates a comprehensive incident report, including the investigation findings and actions taken.
• An Orchestration Agent coordinates the execution of these specialized agents to automate the end-to-end security operations workflow.

Implementing the Solution

• The presentation demonstrates the implementation of the multi-agent solution using the Strand Agents framework within the Bedrock Agentcore platform.
• Key steps include:
  1. Setting up the Agent Gateway and configuring access to internal tools and systems.
  2. Creating the Investigation Agent with a system prompt and access to the necessary tools.
  3. Implementing the Containment Helper and Containment Actor Agents to handle remediation.
  4. Designing a Graph-based orchestration pattern to coordinate the execution of the specialized agents.
  5. Deploying the agents to the Bedrock Agentcore platform using the provided toolkit.

Ensuring Deterministic Behavior

• To ensure the agents behave in a predictable and controlled manner, the presentation suggests the following techniques:
  1. Using Pydantic models to define structured output formats for the agents.
  2. Leveraging hooks to intercept and customize the execution of agent actions.
  3. Nesting multi-agent patterns to handle different types of resources (e.g., EC2 instances, Lambda functions, databases) within the overall security operations workflow.

Business Impact and Real-World Applications

• The multi-agent solution based on Bedrock Agentcore can significantly improve the efficiency and effectiveness of security operations by automating repetitive tasks and enabling faster incident response.
• Key benefits include:
  • Reduced manual effort and operational burden for security teams.
  • Faster investigation, remediation, and reporting of security incidents.
  • Improved consistency and reliability of security operations.
  • Ability to scale the solution to handle a variety of security alerts and use cases.

Conclusion

The presentation demonstrates how leveraging multi-agent collaboration within the Amazon Bedrock Agentcore platform can transform security operations by automating the investigation, remediation, and reporting workflows. This approach can lead to significant improvements in efficiency, responsiveness, and consistency, ultimately enhancing an organization's overall security posture.
