The Evolution of Enterprise Security from Stone Walls to Firewalls - Stefanini

The Evolution Of Enterprise Security From Stone Walls To Firewalls

From the castles with fortified walls and selective gates of yesteryears to today’s intricate digital world, securing entities has always been paramount. Just as medieval cities were safeguarded against threats, modern enterprises, governments, and even home networks require protection.

However, as these institutions grow in size and complexity so does their network infrastructure – making it increasingly difficult to manage and secure.

 Shielding today’s network comes down strikingly similarly – we begin at OSI Layer 1 or physical security which ensures no one can intrude by merely plugging a cable into a switch. From here on up till layer 7 starts our discussion about Network Security across different layers within an enterprise.

Diving into Layer 2 Network Security measures provides us insights on how organizations enhance resilience while securing local network infrastructures; MAC Address Filtering, Port Security, VLAN Segmentation and 802.1x Authentication are just some techniques helping deter unauthorized access while simultaneously counteracting various datalink-layer attacks.

When we scale up to Layer 3 security procedures things start getting broader—a myriad list of processes that includes ACLs (Access Control Lists), Routing Protocols Security, IPSEC (Internet Protocol Security), VPNs (Virtual Private Networks), NAT (Network Address Translation) — all culminating in the quintessential cornerstone for any secure enterprise framework—Firewalls & IPS systems.

For years now enterprises have benefitted enormously from Next-Generation Firewalls due not only to their standard router capabilities but also for offering well-rounded security solutions like TCP/IP Filtering, UDP/TCP Port Management along with Connection State Monitoring & Packet Inspection—all bundled together!
