Blog 48 # Understanding the Attack Tree

An attack tree is a graphical representation of the different ways an attacker could exploit a system. It can be used to identify the most likely and dangerous attack vectors, and to prioritize security controls.

The attack tree shown above is for the threat of an attacker intercepting a message. The attacker could do this by:

1. User Download Malware: The attacker could trick the user into downloading malware, which would then give the attacker access to the user's computer and allow them to intercept messages.

• Train users on security fundamentals: Users should be trained on security best practices, such as how to identify and avoid phishing attacks.
• Install anti-malware software: Anti-malware software can help to protect users from malware attacks.

2. Authorization Mechanism Fail: The attacker could exploit a vulnerability in the authorization mechanism, which would allow them to access messages that they are not authorized to see.

• Implement checks in the authorization module: The authorization module should be designed to be resistant to attack.

3. Message Transmit in Plaintext: The attacker could intercept messages that are being transmitted in plaintext, which would allow them to read the messages without any encryption.

• Implement support for TLS or Other transport encryption technology: Messages should be transmitted over a secure connection, such as TLS.

By implementing these controls, organizations can reduce the risk of an attacker intercepting messages.
