Network Security

What is Network Security?

Network security refers to an organization’s strategy, technologies, devices, procedures, and other provisions for ensuring the security of information assets and all network traffic.

It encompasses all physical and software measures that a business puts in place to protect networks from unauthorized access, misuse, destruction, and modification by insiders (employees, contractors, vendors) and outsiders (cybercriminals, hacktivists, other intruders).

Network security features rules and configurations that companies design and implement to protect the integrity, confidentiality, and accessibility of computer networks and data.

Key Takeaways


Importance of Network Security

Businesses design and implement complex network architectures. These setups face a dynamic threat environment and attackers that are always exploring and exploiting vulnerabilities.

Lack of adequate network security solutions can result in cyberattacks that cause system downtimes, widespread disruption, and extensive damage to an organization’s bottom line and reputation.

Every organization requires a reasonable degree of network security solutions to protect corporate networks and systems from frequent and sophisticated cyber threats. Understanding the different network security components enables an organization to create a secure environment for computers, applications, and users.

Network Attacks

Networks are subject to numerous attacks from different sources. Network attacks include:

Network Security Fundamentals

The fundamentals of network security include:

  1. Physical Network Security: organizations implement physical controls to prevent unauthorized personnel from gaining physical access to network components such as routers, access points, server rooms, and cabling cabinets. Physical network security feature controls such as locks, alarms, CCTV, and biometric authentication.
  2. Technical Network Security: technical controls protect data at rest and in transit in a network. They feature measures that prevent unauthorized access and malicious activities from insiders.
  3. Administrative Network Security: Administrative controls consists of security policies and processes that control user behavior while interacting with the network. Administrative security encompasses measures such as user authentication, access control, and network change and configuration management.

Many security tools and applications address network threats to maintain the confidentiality, integrity, and availability of information and systems.
