Final answer:
To create a secure network design, segment the network and install a UTM, SIEM, and endpoint security software. Additional security products to consider are DLP, NAC, and IAM.
Step-by-step explanation:
To implement a secure network design, we will start by segmenting the network to isolate different departments and servers. We will create separate VLANs for Production, Finance, HR, file servers, ftp server, web server, backup server, and printers. This will prevent lateral movement and reduce the attack surface.
Next, we will install a UTM (Unified Threat Management) device at the network perimeter. The UTM will provide firewall capabilities, intrusion detection and prevention, antivirus, web filtering, and VPN services. It will help protect against external attacks.
For internal security, we will deploy an SIEM (Security Information and Event Management) solution. The SIEM will collect and analyze logs from different devices, applications, and servers. It will help detect and respond to internal threats and policy violations.
To secure workstations, we will use endpoint security software. This software will provide real-time protection against malware, ransomware, and other threats. It will also enforce security policies and prevent unauthorized access.
Additional security products that can be considered are:
- Data Loss Prevention (DLP): To prevent sensitive data from leaving the network.
- Network Access Control (NAC): To enforce security policies for devices connecting to the network.
- Identity and Access Management (IAM): To ensure only authorized users have access to resources.
