Fundamentals of Secure Software - Broken Access Control

The video tutorial discusses broken access control, emphasizing the difference between authorization and authentication. It highlights common weaknesses and vulnerabilities in access control systems, such as unauthorized access and privilege escalation. The tutorial provides prevention techniques, including denying access by default and implementing centralized control mechanisms. Examples of broken access control are illustrated, showing how attackers can exploit these vulnerabilities.

What is the primary difference between authentication and authorization?

• Authentication verifies identity, while authorization grants access to resources.

• Authentication grants access to resources, while authorization verifies identity.

• Both authentication and authorization are the same.

• Authentication is only used in digital systems, while authorization is used in physical systems.

What is the impact of access control failures?

• Increased system performance

• Enhanced data encryption

• Unauthorized information disclosure and data modification

• Improved user experience

Which of the following is a common vulnerability in access control?

• Encrypting data at rest

• Bypassing access control checks by modifying URLs

• Implementing two-factor authentication

• Using strong passwords

What is a key prevention technique for broken access control?

• Implementing access control mechanisms once and reusing them

• Allowing all users access by default

• Using weak encryption methods

• Disabling all logging features

Which technique helps in minimizing harm from automated attacking tools?

• Using outdated software

• Allowing unrestricted access to all users

• Rate limiting API and controller access

• Disabling all security features

How can attackers exploit broken access control to gain unauthorized access?

• By using two-factor authentication

• By encrypting their data

• By modifying account parameters in the browser

• By using strong passwords

What is an example of a broken access control scenario?

• An attacker modifying a URL to access admin pages

• An attacker using a valid password

• An attacker using a VPN

• An attacker encrypting their data
