Final answer:
To protect the usea company network, implement a firewall, set up VLANs for segmentation, enforce strong access controls, use IDS/IPS for threat detection, install updated antivirus software, and ensure a robust backup strategy with regular testing.
Step-by-step explanation:
To design a network that protects the usea company with 50 users, 2 file servers, 1 FTP server, 1 web server, 1 backup server, and 2 printers across 3 departments - production, finance, and HR, several security measures need to be implemented.
Firstly, it is crucial to establish a robust firewall system to monitor and control incoming and outgoing network traffic. The firewall serves as the first line of defense by establishing a barrier between your trusted internal network and untrusted external networks. Secondly, VLANs (Virtual Local Area Networks) can segment the network based on departments, restricting access to resources and minimizing traffic to only those users who require it. This segmentation not only improves performance but also enhances security by limiting the scope of a potential breach. Thirdly, access controls should be enforced to ensure that only authorized personnel have access to sensitive data. Implementing solid password policies and two-factor authentication are key elements here.
Intrusion Detection Systems (IDS) or Intrusion Prevention Systems (IPS) can be utilized to detect and prevent threats in real-time. Regularly updated antivirus software should be installed on all servers and workstations to detect and eliminate malware. Lastly, a comprehensive backup strategy will ensure that the company can recover quickly from data loss; this should include regular testing of backup restores.
