Overview of Security Architecture in My Home Lab

This blog explains a breakdown of what I am learning on Security Architecture

Network Topology

Internet → Virtual Firewall → Switch (Virtual) → VMs (SIEM, AD, Linux, Attacker Machine)
                                    ↘ Separate VLANs for Isolation

IP Addressing

• VLAN | Purpose | Subnet
• Mgmt VLAN | Admin management | 192.168.1.0/24
• Workstation VLAN | User machines | 192.168.2.0/24
• Server VLAN | AD, SIEM, etc. | 192.168.3.0/24
• Attacker VLAN | Kali Linux | 192.168.99.0/24
