Network security involves implementing measures to protect computer networks from unauthorized access, misuse, or attacks. It encompasses a range of technologies, policies, and practices aimed at safeguarding data integrity, confidentiality, and availability. Key components include:
1. Firewalls: Control incoming and outgoing traffic based on security rules.
2. Intrusion Detection Systems (IDS): Monitor network traffic for suspicious activities.
3. Encryption: Protect data in transit and at rest by converting it into a secure format.
4. Access Controls: Restrict who can access the network and its resources.
5. VPNs: Provide secure remote access to the network.
6. Security Policies: Establish guidelines and procedures for maintaining network security.
Overall, effective network security is crucial for protecting sensitive information and ensuring the smooth operation of business functions.
