The "T" in STRIDE Threat Model

C.

Explanation - Any application that sends data to the user will face the potential that the user could manipulate or alter the data, whether it resides in cookies, GET or POST commands, or headers, or manipulates client-side validations.

If the user receives data from the application, it is crucial that the application validate and verify any data that is received back from the user.

The STRIDE threat model is a framework used to identify and classify potential security threats in software systems. Each letter in the acronym STRIDE represents a specific type of threat. The "T" in STRIDE stands for "Tampering with data".

Tampering with data refers to any unauthorized modification of data, whether it be altering, deleting, or inserting data into a system. Tampering with data can result in severe consequences, including loss of confidentiality, integrity, and availability of data. Attackers who are able to modify data can undermine the trustworthiness of the system, deceive users, and cause damage to the organization.

Examples of tampering with data include modifying a user's account information, altering financial transactions, changing the values in a database, or manipulating the contents of a file. Tampering with data can occur at any point in the data lifecycle, from the time it is created to the time it is deleted.

To prevent tampering with data, it is important to implement strong access controls, employ encryption techniques, and validate input data. Additionally, it is important to regularly monitor the system for any signs of unauthorized access or modification. By understanding the potential threats posed by tampering with data and taking steps to mitigate these risks, organizations can better protect their data and ensure the security of their systems.
