Hardware Trojans can be triggered in different ways. A Trojan can be internally activated, which means it monitors one or more signals inside the IC. The malicious circuitry could wait for a count down logic an attacker added to the chip, so that the Trojan awakes after a specific time-span. The opposite is externally activated.
Cyberweapons are commonly defined as malware agents employed for military, paramilitary, or intelligence objectives as part of a cyberattack.This includes computer viruses, trojans, spyware, and worms that can introduce malicious code into existing software, causing a computer to perform actions or processes unintended by its operator.
One could observe that the most effective way to mitigate a threat on the attack tree is to mitigate it as close to the root as possible. Although this is theoretically sound, it is not usually possible to simply mitigate a threat without other implications to the continued operation of the system.
One of the most effective ways to prevent electromagnetic attacks is to make it difficult for an attacker to collect an electromagnetic signal at the physical level. Broadly, the hardware designer could design the encryption hardware to reduce signal strength [ 25 ] or to protect the chip.
Cache attack — attacks based on attacker's ability to monitor cache accesses made by the victim in a shared physical system as in virtualized environment or a type of cloud service. Timing attack — attacks based on measuring how much time various computations (such as, say, comparing an attacker's given password with the victim's unknown ...
The attack surface of a software environment is the sum of the different points (for "attack vectors") where an unauthorized user (the "attacker") can try to enter data to, extract data, control a device or critical software in an environment. [1] [2] Keeping the attack surface as small as possible is a basic security measure. [3]
The Participants are one or more entities that are required for this attack to succeed. This includes the victim systems as well as the attacker and the attacker’s tools or system components. The name of the entity should be accompanied by a brief description of their role in the attack and how they interact with each other. Process Diagram
Intrusion kill chain for information security [1]. The cyber kill chain is the process by which perpetrators carry out cyberattacks. [2] Lockheed Martin adapted the concept of the kill chain from a military setting to information security, using it as a method for modeling intrusions on a computer network. [3]
