Understanding JWT Security Boundaries for Technology Managers

JSON Web Tokens (JWTs) are important tools in the world of technology. However, understanding their security limits is crucial, especially for technology managers overseeing digital projects. The goal of this article is to break down these security aspects so they are easy to understand.

What is a JWT?

JWT stands for JSON Web Token. It's a way to securely send information between two parties as a JSON object. JWTs are compact, easy to use, and they contain a lot of information. They are often used in authentication, which means proving who you are to a computer system.

Key Security Points of JWT

1. Confidentiality is Not a Core Feature

• What: JWTs do not keep data secret.
• Why: The information inside a JWT is base64-encoded, not encrypted. This means anyone who gets hold of it can read it.
• How: To truly secure sensitive data, you should encrypt the data inside the JWT or use an additional layer of security like HTTPS.

2. Validity and Integrity are Vital

• What: JWTs use signatures to ensure the data has not changed.
• Why: A valid signature confirms that the token is trustworthy and the data isn't tampered with.
• How: Check the signature with a secret key that only the server knows. This ensures safe communication.

3. Expiry Times are Crucial

• What: JWTs have expiration times to enhance security.
• Why: Tokens that live forever can be risky. If someone steals a token, they might use it for a long time if there's no expiry date.
• How: Always set a reasonable expiration time to keep your system safe.

Common JWT Security Mistakes

1. Hardcoding Secrets: Don't put your secret keys directly in the code. Instead, use secure environments to store and manage them.
2. Ignoring Algorithms: Be aware of the algorithm used for signing the JWT. Avoid insecure algorithms like "none"which bypass signature verification.
3. Missing Validation: Always validate the JWT on every request against your secret key.
