To quickly locate abnormal domain name access issues using ECDN (Enterprise Content Delivery Network), you can follow these steps:

  1. Monitor Traffic Anomalies: Utilize the real-time traffic monitoring features of ECDN to identify any sudden spikes or drops in traffic that could indicate an issue.

    • Example: If a website experiences a tenfold increase in traffic suddenly, it might be due to a DDoS attack or a misconfigured caching rule.

  2. Check Access Logs: Analyze the access logs provided by ECDN to pinpoint unusual patterns or failed requests.

    • Example: A high number of 404 errors for specific URLs could suggest a problem with content delivery or a recent update that broke links.

  3. Use Geo-Location Data: Examine where the requests are originating from. Unusual geographic distributions might indicate fraudulent activity or misconfigured DNS settings.

    • Example: If most of your traffic suddenly comes from a country where you don’t have a significant user base, it could be a sign of malicious activity.

  4. Implement Alerting: Set up alerts for specific metrics that, when exceeded, notify you immediately. This allows for quick response to issues.

    • Example: Configure an alert for when the number of failed login attempts exceeds a certain threshold, which could indicate a brute force attack.

  5. Analyze Performance Metrics: Look at metrics like latency, packet loss, and throughput to identify if there are issues with content delivery.

    • Example: High latency could indicate network congestion or an issue with the edge servers.

  6. Review Security Logs: Check security logs for any signs of unauthorized access attempts or other security threats.

    • Example: Multiple failed SSH login attempts from a single IP address could suggest a brute force attack.

For enhanced capabilities and more detailed analytics, consider leveraging services like Tencent Cloud’s Cloud Monitor and Security Center, which offer comprehensive tools for monitoring, alerting, and securing your cloud infrastructure and applications.
