In today's digital age, fully remote non-profit organizations face unique challenges in securing their networks and protecting sensitive data. This guide aims to provide a detailed roadmap for setting up a secure, efficient, and scalable network infrastructure using open-source tools and best practices tailored for remote working environments.
Establish secure remote access using:

- Private Zone: Internal resources accessible via VPN.
- Restricted Zone: Sensitive data with limited access.
-
Use VLANs:
- Configure VLANs on network devices to separate traffic logically.
-
Firewall Configuration:
- Use firewalls to control traffic between VLANs.
- Apply strict rules based on the principle of least privilege.
-
Regular Audits:
- Review network configurations periodically.
- Ensure segmentation remains effective as the network evolves.
Set up centralized logging and monitoring to detect and respond to threats effectively.
-
Install ELK Stack:
- Elasticsearch: Stores and indexes log data.
- Logstash: Processes and ingests logs from various sources.
- Kibana: Visualizes data and creates interactive dashboards.
-
Configure Log Sources:
- Collect logs from servers, firewalls, VPNs, applications, and endpoints.
-
Set Up Dashboards:
- Monitor key metrics such as login attempts, network traffic, and system errors.
-
