How does proper API key rotation mitigate security risks associated with compromised credentials?

API key rotation mitigates security risks from compromised credentials by regularly replacing existing API keys with new ones. An 'API key' is a unique identifier used to authenticate requests to an API (Application Programming Interface). If an API key is compromised, meaning it's been exposed to unauthorized parties, those parties can use it to access the API and potentially perform malicious actions, such as stealing data or disrupting services. API key rotation involves generating a new API key and deactivating the old one. This limits the window of opportunity for attackers to exploit a compromised key. Even if an attacker gains access to an API key, it will only be valid until the next rotation. Proper key rotation also includes securely storing and managing API keys. This means using encryption, access controls, and auditing to prevent unauthorized access to the keys themselves. For example, if a developer accidentally commits an API key to a public code repository like GitHub, rotating the key will invalidate it, preventing anyone who finds it from using it to access the Weather.com API. Regularly rotating API keys, combined with secure storage practices, significantly reduces the risk of long-term damage from compromised credentials.
