SOC / Log Analytics and Reporting

Our CDSEC Green Wall will send their log data and alerts to our centralized SIEM environment. For this, we host a Graylog server and send all the logs, secured with TLS encryption.

Services:
- Logs get analyzed in Graylog. There the IP addresses will be looked up and, if malicious, reported to us. We will alert you of any hostile or dubious behavior.
- We offer weekly reports with a graphical display of all the traffic including a summary. The frequency of the reporting may be altered if requested.
- We monitor the traffic and the health of the firewall live in Grafana. There we have an additional dashboard to recognize odd behavior that may indicate a threat. If we find something questionable, we will immediately alert you to address and solve this problem.
Versions:
- The Green Wall Firewall service is offered as a Software as a Service (SaaS) or as Managed Security Service (MSS).
- With SaaS, you will receive the Green Wall Firewall appliance in combination with a cloud-hosted Log Analytics platform helping you to monitor and analyze your in and outgoing communication. The SaaS environment is hosted inside Azure Cloud and the CDSEC Solution LLC support team is taking care of maintaining the software and operating system while the customer's responsibility is on day-to-day log analytics.
- In case you don't have the expertise or people inside your organization CDSEC Solution LLC can manage the environment and Security Solution on behalf of the customer in a fully managed solution.
