AWS limits AI agents’ data access, even when manipulated

Help Net Security
Amazon

Overview

Amazon Web Services (AWS) has introduced a new method to ensure AI agents respect user access controls when retrieving data. This approach allows authorization context to flow through AI agents, meaning that access restrictions are enforced by AWS infrastructure and downstream services rather than relying solely on the AI agent itself. This is particularly important for users of the Amazon Bedrock AgentCore, who can develop AI agents that draw information from various sources like Amazon DynamoDB and internal knowledge bases. Without proper context about the user making a request, AI agents could inadvertently disclose sensitive information. By implementing these controls, AWS aims to enhance data security and prevent unauthorized access, which is crucial for businesses handling sensitive data.

Key Takeaways

  • Affected Systems: Amazon Bedrock AgentCore, Amazon DynamoDB, internal knowledge bases
  • Action Required: Implement the new authorization context method as described by AWS to ensure AI agents enforce access controls.
  • Timeline: Newly disclosed

Original Article Summary

AWS has detailed an approach for propagating user authorization context through AI agents, allowing access controls to be enforced by infrastructure and downstream services rather than relying on the agent itself. Customers using Amazon Bedrock AgentCore can build AI agents that pull information from Amazon DynamoDB tables, document repositories, SaaS platforms, and internal knowledge bases to answer questions and automate workflows. Without awareness of the user making a request, however, an agent could return information … More → The post AWS limits AI agents’ data access, even when manipulated appeared first on Help Net Security.

New TCG guidance gives buyers a way to test PQC-ready TPM claims

Help Net Security

The Trusted Computing Group (TCG) has released new guidelines for Trusted Platform Modules (TPMs), which are essential components that secure a device's cryptographic keys and firmware integrity. These guidelines specifically address how TPMs can be deemed quantum-safe, a growing concern as quantum computing technology advances. Now, buyers can request proof from vendors that their TPMs meet these new standards, ensuring they are prepared for future quantum threats. This is significant for companies looking to protect their data from potential quantum attacks, as it provides a way to verify the security claims made by manufacturers. The move aims to enhance the overall security landscape as businesses transition to quantum-resistant technology.

Developer alleges Alibaba uses audio fingerprinting for web tracking

SCM feed for Latest

Matt Callaghan, a software engineer, has raised concerns that Alibaba's website may be using audio fingerprinting techniques for tracking users. He found that the site employs obfuscated audio scripts that create a waveform and analyze its output, which could allow the company to monitor user behavior in a way that bypasses traditional tracking methods. This discovery raises significant privacy issues, as it suggests that users may be unwittingly tracked through audio signals emitted from their devices. The implications are serious, especially for individuals who value their privacy online. The use of such techniques could lead to increased scrutiny from regulators and may prompt users to reconsider their interactions with the site.

Unpatched Calix flaw lets hackers bypass NAT to expose internal devices

BleepingComputer

A vulnerability in Calix GS7 XGS residential routers, specifically the GS5239XG model, has been discovered, allowing attackers to bypass Network Address Translation (NAT) settings. This flaw enables remote, unauthenticated users to set up port-forwarding rules, which could expose internal devices on a user's local network to the public internet. The issue affects multiple broadband providers in the U.S. and poses significant risks as it could lead to unauthorized access to sensitive devices within homes. As of now, the vulnerability remains unpatched, leaving users at risk of potential exploitation unless action is taken to secure their networks. It's crucial for users of these routers to remain vigilant and consider disabling remote management features until a fix is provided.
