What is need of Network Security? Explain its different elements of Network Security.
Network security is essential to protect data, systems, and infrastructure from unauthorized access, misuse, and disruption. It ensures confidentiality, integrity, and availability of information on a network, safeguarding against threats such as malware, hackers, and data breaches.
Elements of Network Security:
Firewalls: Monitor and control incoming and outgoing network traffic, filtering based on predetermined security rules.
Intrusion Detection Systems (IDS): Monitor network traffic for suspicious activities or patterns that may indicate unauthorized access or attacks.
Encryption: Protects data by converting it into a code that can only be deciphered with the appropriate decryption key.
Access Control: Limits access to network resources based on user credentials, roles, and permissions.
Antivirus Software: Detects, prevents, and removes malware infections on devices connected to the network.
Virtual Private Network (VPN): Establishes secure, encrypted connections over public networks, ensuring data confidentiality and privacy.
These elements work together to establish a robust network security posture, mitigating risks and vulnerabilities.
