The following description presents an example of an attack tree in the aviation domain. This scenario will focus on potential threats to an aircraft's avionics systems. Create a graphical representation of it. Use a specialized tool or the word to create it. It does not accept a photo of a handwritten solution. Root Goal: Compromise Avionics Systems • The attacker's primary objective is to compromise critical avionics systems, potentially endangering flight safety. Attack Paths: 1. Exploit Weak Authentication: a. The attacker targets authentication mechanisms within the avionics network. b. Sub-Attack Tree 1.1: Unauthorized Access to Flight Control Systems: i. The attacker attempts to bypass authentication and gain access to flight control interfaces. ii. If successful, they could manipulate flight parameters (e.g., alter altitude, heading, or speed). c. Sub-Attack Tree 1.2: Access to Navigation Systems i. The attacker gains unauthorized access to navigation systems (e.g., GPS, inertial navigation). ii. Manipulating navigation data could lead to incorrect course calculations or misdirection. 2. Physical Tampering: a. The attacker physically accesses avionics components (e.g.. cockpit instruments, sensors). b. Sub-Attack Tree 2.1: Malicious Hardware Insertion i. The attacker introduces rogue hardware (e.g., compromised sensors, malicious chips). ii. This could disrupt sensor readings, affecting flight stability and safety. c. Sub-Attack Tree 2.2: Circuit Board Tampering i. The attacker modifies circuit boards within avionics equipment. ii. Introducing subtle faults could lead to unpredictable behavior during flight. 3. Network Attacks: a. The attacker exploits vulnerabilities in avionics communication networks. b. Sub-Attack Tree 3.1: Man-in-the-Middle (MitM) Attack i. The attacker intercepts avionics communication. ii. Altering data between systems (e.g., airspeed data) could mislead pilots. c. Sub-Attack Tree 3.2: Denial-of-Service (DoS) Attack i. The attacker floods avionics communication channels, disrupting critical messages. ii. Flight control commands or navigation updates may be delayed or lost.
