Description: A blocklist is a list of entities that are denied access to a particular resource. This resource can be a system, a network, an application, or any other type of digital asset. Blocklists are fundamental tools in managing cybersecurity, as they allow administrators to control who can or cannot access certain resources, thereby helping to protect sensitive data and prevent unauthorized access. These lists can include IP addresses, usernames, domains, or any other entity deemed risky. The implementation of blocklists is a common practice in various areas of cybersecurity, including security management in networks, intrusion detection and prevention systems, and protection against DDoS attacks. Additionally, they are essential in identity and access management, where the goal is to restrict access to critical information. Blocklists can be dynamic, updating in real-time in response to emerging threats, or static, remaining constant over time. Their effectiveness lies in their ability to adapt to different contexts and security needs, making them a key component in defending digital infrastructures.
