Surveillance refers to the monitoring of individuals, groups, or systems, often using technology such as cameras, software, or network tools, to collect information or observe behavior. In cybersecurity, surveillance can involve tracking online activities, monitoring network traffic, or analyzing data to detect threats, prevent unauthorized access, or ensure compliance with security policies. While surveillance can enhance safety and security, it also raises important concerns about privacy, data protection, and civil liberties. Understanding surveillance practices is essential for balancing security needs with the right to privacy.
