suresh What is the purpose of a firewall in a network?
A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. The main purpose of a firewall in a network is to act as a barrier between your internal network and outside sources, such as the internet. It helps to prevent unauthorized access and cyber attacks by filtering and blocking potentially harmful traffic while allowing legitimate communication to pass through.
By implementing a firewall, organizations can protect their sensitive data, secure their network infrastructure, and reduce the risk of cyber threats. Firewalls play a crucial role in maintaining network security and ensuring the confidentiality, integrity, and availability of network resources.
