Ministry of Defence Integrated Network

My CCNA graduation project at Telesom Academy (group "Network Defence Engineers", with Mohamed Ismail). The task: design a secure, scalable enterprise network connecting three sites of a Ministry of Defence: Headquarters, Air Defence and Military Defence. Architecture Each site follows the Cisco hierarchical model: core layer for backbone routing, distribution layer for inter-VLAN routing and policy, access layer for PCs, IP phones, CCTV cameras and wireless access points. Headquarters also hosts a data-center switch with DHCP, DNS, NTP, Syslog and web servers, and connects to two ISPs through redundant edge routers. What I implemented - VLAN segmentation: Users, Voice, CCTV, Admin-IT, Servers, Internal Wi-Fi, Guest and Management (VLAN 10-99). - OSPF as the dynamic routing protocol across all sites, with neighbors verified in FULL state. - HSRP gateway redundancy between distribution switches (active/standby failover). - EtherChannel (LACP) between core and distribution switches for bandwidth and link redundancy. - Security: ACLs protecting the data center, SSH-only management, DHCP Snooping against rogue DHCP servers, Port Security on access ports. - DHCP pools per VLAN, plus centralized Syslog and NTP. Result Every feature was tested and documented with verification output: trunks, EtherChannel, HSRP states, OSPF adjacencies, DHCP assignment and the security controls. The project shows how CCNA concepts come together in a real multi-site design.
