Threat Detection refers to the process of identifying potential or actual cybersecurity threats that could compromise the confidentiality, integrity, or availability of systems, networks, or data. It involves monitoring, analyzing, and responding to suspicious activities or vulnerabilities that may indicate an attack or breach.
Threat detection uses various techniques, such as signature-based detection (matching known attack patterns), anomaly detection (identifying unusual behavior), and behavioral analysis (monitoring user or system actions for deviations). Advanced methods include machine learning and AI to detect sophisticated threats like zero-day attacks or insider threats.
Example:
A company’s security system detects multiple failed login attempts from an unknown IP address within a short time. This unusual activity triggers an alert, indicating a potential brute-force attack. The threat detection system can then block the IP, notify administrators, or initiate further investigation.
In cloud environments, Tencent Cloud offers Host Security (HSM) and Cloud Workload Protection (CWP) to detect threats like malware, unauthorized access, and abnormal process behavior. Additionally, Cloud Security Center (CSC) provides centralized threat visibility, vulnerability management, and real-time alerts to help secure cloud infrastructure.
