Network security refers to the policies, practices, and technologies designed to protect networks and data from unauthorized access,
misuse, or damage. It involves implementing measures to safeguard both the hardware and software that comprise a network.
Key components of network security include:
- Firewalls: Systems that monitor and control incoming and outgoing network traffic based on security rules.
- Intrusion Detection and Prevention Systems (IDPS): Tools that detect and respond to potential threats or breaches.
- Encryption: Techniques that encode data to prevent unauthorized access during transmission or storage.
- Access Control: Mechanisms that restrict access to networks and resources based on user permissions.
- Virtual Private Networks (VPNs): Secure connections that allow users to access a private network over the internet.
- Antivirus and Anti-malware Software: Programs that protect systems from malicious software and viruses.
- Security Policies: Guidelines and protocols that outline how to protect sensitive data and maintain network integrity.
Effective network security aims to protect the confidentiality, integrity, and availability of data and systems, ensuring safe and reliable communication.
