In today’s digital age, where cyber threats are ever-evolving, organizations must prioritize the security of their networks. Firewalls have long been a fundamental component of network security, acting as a barrier between internal networks and external threats. However, simply implementing a firewall is not enough. Firewall monitoring plays a critical role in enhancing network security by continuously observing and analyzing firewall activities. In this blog post, we will explore the concept of firewall monitoring, its benefits, and its key distinctions from TCP and UDP monitoring.
What is a Firewall?
A firewall is a security device or software that monitors and controls incoming and outgoing network traffic based on predefined security rules. It acts as a gatekeeper, examining data packets and determining whether to allow or block them based on the established rule set. Firewalls can be hardware-based (physical devices) or software-based (programs installed on servers or network devices) and are commonly used to protect networks from unauthorized access, malware, and other cyber threats.
