1. Monitoring Tools Setup:
- [ ] Install network monitoring software.
- [ ] Configure monitoring tools to track critical network parameters.
- [ ] Set up alerts for unusual activities or performance thresholds.
2. Network Infrastructure:
- [ ] Verify connectivity of all network devices (routers, switches, firewalls).
- [ ] Ensure proper configuration of VLANs, subnets, and IP addressing.
- [ ] Check physical connections for any signs of wear or damage.
3. Bandwidth Utilization:
- [ ] Monitor bandwidth usage across different segments of the network.
- [ ] Identify bandwidth-intensive applications or devices.
- [ ] Optimize bandwidth allocation to critical services.
4. Network Security:
- [ ] Monitor for suspicious network traffic or unauthorized access attempts.
- [ ] Update firewall rules and intrusion detection/prevention systems.
- [ ] Regularly review access controls and user permissions.
5. Device Health:
- [ ] Check the health status of network devices (CPU, memory, disk usage).
- [ ] Monitor temperature and voltage levels for hardware components.
- [ ] Implement firmware updates for routers, switches, and other devices.
6. Application Performance:
- [ ] Monitor response times and availability of critical applications.
- [ ] Identify and troubleshoot performance bottlenecks.
- [ ] Optimize application configurations for better performance.
7. Network Traffic Analysis:
- [ ] Analyze network traffic patterns to detect anomalies or bottlenecks.
- [ ] Use packet capture tools for in-depth analysis of network packets.
- [ ] Monitor for bandwidth spikes or unusual traffic patterns.
8. Backup and Recovery:
- [ ] Ensure regular backups of network configurations and critical data.
- [ ] Test backup integrity and restoration procedures.
- [ ] Implement disaster recovery plans for network outages or data loss.
9. Documentation:
- [ ] Maintain up-to-date network diagrams and documentation.
- [ ] Document changes to network configurations and policies.
- [ ] Keep records of network performance metrics and incidents for analysis.
10. Regular Maintenance:
- [ ] Schedule regular maintenance tasks such as device reboots and firmware updates.
- [ ] Conduct periodic security audits and vulnerability assessments.
- [ ] Review and update network monitoring policies and procedures as needed.
Note: Customize this checklist according to your specific network environment and requirements.
