OpenAI Unveils Lockdown Mode for Enhanced Security in ChatGPT

OpenAI is launching a new ‘Lockdown Mode’ for ChatGPT, targeting the protection of users and organizations dealing with sensitive data from cyber threats. This optional security feature restricts interactions with external systems to mitigate risks of prompt-injection attacks and data leaks. It’s tailored for high-risk users such as enterprises and security-sensitive professionals, rather than the general public. Enabling Lockdown Mode limits capabilities that could expose confidential information, including web browsing restrictions to cached content, disabling advanced research tools, and reducing access to certain network features. Additionally, OpenAI is implementing “Elevated Risk” labels across its products, providing warnings about features that carry heightened security risks when linked to external applications or the internet. This initiative aims to help users make informed decisions about their security while using AI technology. Overall, the introduction of Lockdown Mode emphasizes OpenAI’s commitment to enhancing user safety and minimizing potential vulnerabilities.
