Router log monitoring and auditing with EventLog Analyzer
Routers are critical components of network infrastructure, responsible for directing traffic between networks to ensure smooth communication and connectivity. Monitoring the performance, security, and health of routers is essential for maintaining network reliability, optimizing traffic flow, and identifying potential security threats. ManageEngine EventLog Analyzer provides advanced router log monitoring and analysis, offering insights into network activities, security events, and performance metrics.
EventLog Analyzer supports a wide range of routers, including Cisco Routers, HP Routers, Arista Routers, Dell Routers, and Huawei Routers.
This tutorial outlines key use cases for monitoring and securing these routers using EventLog Analyzer. To start monitoring router logs effectively, ensure that logs are configured to be forwarded to the EventLog Analyzer server for centralized analysis, reporting, and alerts.
Monitoring routers using EventLog Analyzer: Use cases
EventLog Analyzer provides comprehensive coverage of router monitoring use cases through its predefined security monitoring reports. These reports can be scheduled for generation at specific intervals and distributed via email for streamlined analysis and proactive network management.
| Use Case | Description | Why implement it? | Available Reports |
|---|---|---|---|
| Detect patterns of failed logons or repeated SSH and VPN authorization errors. | Identify patterns of failed logons and repeated SSH or VPN authorization errors to detect potential brute force attacks, credential misuse, or misconfigurations. | Monitoring these patterns helps mitigate security risks by identifying unauthorized access attempts or configuration issues, ensuring networkmintegrity and compliance with security policies. |
|
| Detect critical link state changes, configuration updates, and recurring network errors. | Get insights into events like link up/down, state changes, configuration updates, and link errors. It helps track top users or devices making configuration changes and identifies frequent error sources. | Enables proactive network management by detecting anomalies, minimizing downtime, and ensuring adherence to configuration policies. Supports troubleshooting and compliance efforts by logging and analyzing device-level events. |
|
| Monitor and analyze patterns of allowed network traffic to identify potential anomalies. | Analyze allowed network traffic to pinpoint high-traffic sources, destinations, and protocols. Track trends to detect anomalies that could indicate security vulnerabilities or misconfigured policies. | Helps optimize network performance, ensure compliance with security policies, and proactively identify unusual traffic patterns that may signal unauthorized access or potential breaches. |
|
| Detect and analyze denied network connections to identify unauthorized access attempts and optimize security policies. | This report helps monitor patterns of denied connections, providing insights into blocked traffic by source, destination, and protocol, as well as overall trends. | Enhances security by identifying suspicious or unauthorized activities, fine-tuning access controls, and preventing potential breaches. |
|
| Monitor network traffic by protocol to identify unusual patterns or potential misuse in TCP, UDP, and ICMP communications. | This report provides a detailed audit of network traffic segmented by protocol type, highlighting top sources of TCP, UDP, and ICMP traffic and offering an overview of protocol usage trends. | Enables network administrators to detect anomalies, optimize bandwidth usage, and ensure compliance with organizational traffic policies. |
