Network Security

Definition of Network Security as it relates to Technology, System Administration, Security Management

Network Security encompasses the policies, practices, and technologies implemented to protect networks from unauthorized access, misuse, malfunction, modification, destruction, or improper disclosure. It involves safeguarding data integrity, confidentiality, and availability on all types of networks including local area networks (LANs), wide area networks (WANs), and the internet. This subcategory is deeply intertwined with technology, system administration, and security management as it requires a thorough understanding of underlying systems, their potential vulnerabilities, and the tactics used by malicious actors to exploit them. Network Security experts are tasked with securing network infrastructure by employing various tools like firewalls, intrusion detection systems (IDS), virtual private networks (VPNs), and encryption technologies. They also need to stay abreast of emerging threats and develop strategies to mitigate them effectively.
