Key Terms to Review (49)
Admissibility: Admissibility refers to the legal criteria that determine whether evidence can be considered by a court during a trial. In the context of cybercrime and digital evidence, admissibility is crucial as it ensures that the evidence presented is relevant, reliable, and obtained in a lawful manner. This includes considerations of how digital evidence was collected, preserved, and whether it complies with legal standards for privacy and protection of rights.
Algorithmic bias: Algorithmic bias refers to the systematic and unfair discrimination that can occur when algorithms produce outcomes that are prejudiced due to flawed assumptions in the machine learning process. This bias often stems from the data used to train these algorithms, which may reflect historical inequalities or social prejudices. Consequently, algorithmic bias can impact various fields, including law enforcement and cybersecurity, by influencing decisions and actions based on biased data inputs.
AlphaBay: AlphaBay was a popular dark web marketplace that operated from 2014 until it was shut down in 2017, primarily facilitating the sale of illegal goods and services such as drugs, counterfeit items, and hacking tools. Its structure allowed users to conduct transactions anonymously using cryptocurrencies, making it a prominent player in the realm of cybercrime and digital evidence collection.
Anonymity: Anonymity refers to the state of being not identifiable within a set of subjects, often allowing individuals to act without revealing their personal identity. In the digital age, it plays a crucial role in cybercrime, as perpetrators can commit illegal acts without being easily traced. This lack of identification can complicate law enforcement efforts, as maintaining anonymity can empower both legitimate users seeking privacy and criminals attempting to evade justice.
ASEAN Convention on Cybercrime: The ASEAN Convention on Cybercrime is a regional legal framework established to combat cybercrime and enhance cooperation among ASEAN member states in addressing cyber threats.

This agreement allows law enforcement agencies in both countries to access and exchange digital data more efficiently, which is crucial in combating cybercrime and enhancing public safety. The significance of this agreement lies in its potential to bridge legal and procedural gaps, making it easier for authorities to respond to transnational cyber threats.
VPNs: VPNs, or Virtual Private Networks, are technology tools that create a secure and encrypted connection over a less secure network, such as the internet. They allow users to send and receive data as if their devices were directly connected to a private network, ensuring privacy and security while accessing the web. By masking the user's IP address and encrypting their internet traffic, VPNs play a crucial role in protecting against cybercrime and unauthorized access to digital evidence.
Zero-day exploits: Zero-day exploits are malicious software or techniques that take advantage of vulnerabilities in computer software before the developers have a chance to issue a fix or patch. These exploits are particularly dangerous because they can be used by attackers to gain unauthorized access, steal data, or disrupt services, all while remaining undetected. The term 'zero-day' refers to the fact that developers have had zero days to address the vulnerability since it was discovered, making these attacks highly effective and potentially damaging.
