Overview of Network Security

Network security refers to the policies, practices, and technologies implemented to protect the integrity, confidentiality, and availability of a computer network and its data. It is designed to safeguard against unauthorized access, misuse, disruption, modification, or destruction of network resources.

Importance of network security in modern infrastructure

Protection from Data Breaches: Prevents unauthorized access to personal, financial, and organizational data, safeguarding against identity theft, financial loss, or reputational damage.

Minimizing Downtime: Prevents disruptions caused by attacks such as Distributed Denial of Service (DDoS), which could cripple an organization's ability to function.

Protection Against Malware and Ransomware: Shields systems from malicious software that can corrupt, encrypt, or steal data.

Prevention of Unauthorized Access: Blocks intrusions from hackers attempting to exploit vulnerabilities in the network.

Secure Remote Access: Provides tools like VPNs to ensure employees can work safely from anywhere.
