Create a secure, segmented network diagram for a corporate domain, incorporating critical servers, remote access via VPN, WiFi connectivity, and essential security measures.\ \ Requirements: Domain Components: Web Server, DNS Server, Mail Server, Database, File Server \ Network Zones: DMZ (Demilitarized Zone) for public-facing services, Internal Network for sensitive data and operations \ Remote Access: VPN setup using SHA-256 with IPSEC protocol for secure remote employee connectivity WiFi Connectivity: Two WiFi routers for internal corporate network access \ Security Measures: Firewalls, SIEM (Security Information and Event Management), IDS/IPS (Intrusion Detection System/Intrusion Prevention System)\ Network Segmentation: Separate the internal network into an operations side and a general users side, using VLANs managed by a switch \ Connectivity Policy: Operations side uses a wired network, avoiding WiFi for enhanced security\ \ 1. Design the DMZ: Place the Web Server, DNS Server, and Mail Server in the DMZ. Ensure the DMZ is isolated from the internal network with a firewall.\ 2. Outline the Internal Network: Identify two segments within the internal network: Operations and General Users. Position the Database and File Server within the Operations segment. \ 3. Implement VLANs: Utilize a managed switch to create VLANs that separate the Operations segment from the General Users segment. Ensure the Operations segment is wired, with no WiFi access. \ 4. Configure WiFi Routers: Place two WiFi routers in the General Users segment for internal network access. Apply strong encryption (WPA3) to secure WiFi communications. \ 5. Establish VPN Connectivity: Incorporate a VPN gateway that allows remote employees to securely connect to the corporate internal network. Use SHA-256 with IPSEC protocol for the VPN connection. \ 6. Incorporate Security Measures: Place a firewall between the DMZ and the external network, and another between the DMZ and the internal network. Deploy IDS/IPS systems to monitor and protect network traffic. Set up a SIEM system for real-time analysis of security alerts generated by network devices.\ Security Policies: Strong Encryption: Ensure all data in transit, including VPN connections and WiFi, uses strong encryption protocols. Network Segmentation: Clearly segment the internal network to isolate sensitive operations from general user activities, reducing the risk of lateral movement in case of a breach. Physical and Logical Separation: Maintain a strict separation between the operations network (wired) and the general users network (wireless) to enhance security.
