Network security is essential for preventing which type of threats?

Network security plays a crucial role in protecting systems and data from various cyber threats. The focus of network security is primarily on safeguarding the integrity, confidentiality, and availability of data as it travels across networks. Cyberattacks encompass a wide range of malicious activities including hacking, phishing, malware deployment, and denial-of-service attacks, all of which can compromise sensitive information and disrupt services. By implementing effective network security measures such as firewalls, intrusion detection systems, and encryption, organizations are better prepared to detect and mitigate these sophisticated attacks.

While data leaks, human errors, and physical breaches are significant concerns in the broader scope of information security, they are often addressed through different strategies and controls. Data leaks can arise from vulnerabilities in data management and access controls, human errors are typically managed through training and policies, and physical breaches require physical security measures rather than exclusively network security protocols. Therefore, the primary objective of network security is to defend against cyberattacks, making it the most relevant option in the context of this question.
