In the modern digital landscape, where cyber threats are constantly evolving, firewalls serve as one of the most essential security tools for protecting organizational networks. A firewall operates as a barrier between a secure internal network and untrusted external environments, such as the internet. It analyzes network traffic and enforces rules that determine which data packets are allowed to pass through and which should be blocked. Firewalls can either be software-based, installed on individual devices, or hardware-based, existing as dedicated physical appliances within a network. Their primary objective is to…

Understanding Cybersecurity Roles and the Shift from Perimeter to Layered Security The Foundation of Cyber Defense In the ever-evolving world of cybersecurity, organizations depend on skilled professionals to protect their digital infrastructure. Just as a military operation assigns roles based on skill, experience, and strategic importance, so too do cybersecurity teams. Within this structure, two pivotal roles stand out: the security engineer and the security analyst. While both are essential in combating cyber threats, their responsibilities, hierarchy, and expertise levels differ. Security engineers typically earn more than analysts, with a…
