A firewall is a crucial component in any network security architecture. While off-the-shelf solutions are widely available, there may be scenarios where designing a custom firewall is necessary—whether for specialized applications, unique traffic filtering needs, or educational purposes. This blog provides a comprehensive overview of how to design and implement your own firewall.
Firewalls are essential components of modern network security, serving as a protective barrier between trusted and untrusted networks. Whether on-premises or in the cloud, firewalls monitor and control traffic to enforce security policies. This blog explores the role of firewalls in operating systems (OS) and cloud environments, highlighting their similarities, differences, and best practices for cloud usage.
When discussing ports in the context of operating systems, it's essential to understand how they relate to networking. Ports are integral to the TCP/IP and UDP protocol stacks, enabling multiple communication endpoints to coexist on a single machine. This blog delves into the technicalities of how many ports an OS can support, the factors that influence this number, and practical considerations for their usage.
