Work IQ: REST endpoint tools

🚨 The Signal: Copilot agents can now use REST endpoints as tools, enabling them to interact with external systems. This expands agent capabilities but introduces new attack surfaces for data exposure and unauthorised actions.

The Impact

Security teams and AI governance teams are affected by the increased risk of data exfiltration and unauthorised access via agent-controlled REST endpoints.

• Security teams face increased risk of data exfiltration if agent access to REST endpoints is not properly secured.
• AI governance teams must update policies to manage agent identities and their permissions to external systems.
• Data owners are at risk of unauthorised data modification or disclosure if agents are compromised or misconfigured.
• Compliance officers need to ensure agent interactions with external systems meet regulatory and policy requirements.

The Action

1. Review and define clear policies for agent identity and access management (IAM) to external REST endpoints.
2. Implement least privilege principles for all agent-assigned permissions to external services.
3. Establish robust logging and monitoring for agent interactions with REST endpoints to detect anomalous activity.
4. Conduct regular security audits of agent configurations and their integrated REST endpoint tools.
5. Develop incident response plans specifically for compromised agent identities or unauthorised agent actions.
