Practical, Step-by-Step Curriculum
Curated by senior network security engineers in Surat. 80% practical Cisco packet tracing and firewall labs.
Networking Fundamentals & The OSI / TCP/IP Models
Understand how data traverses networks. Master the 7 layers of the OSI model, TCP/IP protocol suite, MAC addressing, IPv4 addressing, Ethernet frame structures, and packet flow mechanics.
IP Addressing & Advanced Subnetting (VLSM)
Design scalable network addressing plans. Master IPv4 classful vs CIDR notation, subnet masks, Variable Length Subnet Masking (VLSM) calculations, and IPv6 addressing basics.
Switching & Local Area Network (LAN) Security
Segment enterprise networks. Master Virtual LANs (VLANs), 802.1Q trunking, Spanning Tree Protocol (STP), switch port security against MAC flooding, and DHCP Snooping.
Routing Protocols & Address Translation (NAT)
Connect disparate networks. Master static routing, dynamic OSPF routing between branch offices, default gateway routing, Port Address Translation (PAT), and Access Control Lists (ACLs).
Deep Packet Analysis with Wireshark
Inspect network traffic at the byte level. Master Wireshark capture filters, display filters, TCP 3-way handshake analysis, diagnosing network latency, and detecting rogue scanning activity.
Firewall Deployment & Encrypted VPN Tunnels
Defend network perimeters. Learn stateful inspection firewalls (pfSense / Fortinet basics), inbound and outbound traffic filtering rules, site-to-site IPsec VPNs, and remote worker OpenVPN access.
