Network security threats are potential dangers or malicious activities that could compromise the confidentiality, integrity, or availability of a computer network and its data. These threats exploit vulnerabilities within network infrastructure, software, or human behavior to achieve harmful objectives. Understanding these threats is crucial for implementing effective security controls and defense strategies to protect digital assets. For instance, a denial-of-service attack aims to overwhelm a network's resources, making it inaccessible to legitimate users. While often discussed generally, specific threat types like malware or phishing have distinct characteristics and mitigation techniques. Knowledge of network security threats is fundamental for certifications such as CompTIA Security+, CySA+, and CISSP.
