Firewall

Definition of Firewall as it relates to Technology, Network Security, Data Privacy

Firewall is a security measure that controls and monitors incoming and outgoing network traffic based on predetermined security rules. It serves as a barrier between trusted internal networks and untrusted external networks, such as the internet. In the context of technology, firewalls are essential for network security and data privacy. They help prevent unauthorized access to or from a private network, safeguarding sensitive information and maintaining system integrity. As part of a comprehensive network security strategy, firewalls can be configured to block traffic from specific sources, allow traffic only from authorized sources, and protect vulnerable systems from targeted attacks. In the hierarchy of Technology/Network Security/Data Privacy, a firewall is a critical component that ensures secure communication channels, maintains confidentiality, and prevents unauthorized data access or manipulation.
