Description: The ‘Blacklist’ refers to the practice of denying access to a list of known malicious entities, which can include IP addresses, domains, emails, or software. This mechanism is fundamental in cybersecurity, as it allows organizations to protect their systems and networks from potential threats. By identifying and blocking these entities, the risks of cyberattacks, fraud, and other malicious activities are minimized. Blacklists are used in various areas, including public key infrastructure, where untrusted digital certificates can be blocked, and in network security, where unauthorized access to devices and services is prevented. Additionally, in the context of security orchestration, blacklists help automate incident response by automatically filtering malicious traffic. In the realm of the Internet of Things (IoT), they are used to protect connected devices from known attacks. In summary, blacklists are an essential tool in the cybersecurity defense strategy, allowing organizations to maintain a safer and more controlled environment.
