MoreYeahs built a monitoring and response process for critical and high-severity security alerts across a client's Google Cloud environment.
The client needed to monitor, investigate, and troubleshoot intrusion detection alerts across its Google Cloud environment, handling a range of critical and high-severity threats with minimal manual overhead.
The environment generated a range of critical and high-severity security alerts that needed fast, consistent handling.
Varied Attack Types — Alerts spanned SQL injection, cross-site scripting (XSS), HTTP shadow access attempts, HTTP unauthorized brute-force attacks, and denial-of-service (DoS) attacks.
High-Stakes Alerts — Each alert type carried critical or high-severity impact if left unaddressed.
Manual Investigation Burden — Investigating and correlating each alert manually was slow and labor-intensive.
MoreYeahs set up a monitoring and response process that extracts metadata and context from each alert and drives it through to remediation.
Alert Metadata Extraction — Set up a monitoring system for critical and high alerts that extracts metadata and context to enable rapid action.
Log Correlation — Reviewed load balancer logs to correlate incidents with source IP addresses.
Unauthorized Access Review — Evaluated logs to identify IP addresses behind unauthorized access attempts.
Containment — Blocked identified IP addresses to prevent further attacks.
Configuration Hardening — Reviewed and reconfigured load balancer settings to avoid repeat attacks.
Continuous Follow-Up — Maintained ongoing monitoring to confirm implemented measures stopped the attacks.
The response process relied on Google Cloud's native security and networking tooling.
The process gave the client faster, more consistent handling of security alerts.
Accelerated Log Monitoring — Faster review and correlation of security-relevant logs.
Stronger Security Enablement — Confirmed attacks were stopped through IP blocking and configuration changes.
The engagement gave the client a repeatable process for handling future intrusion attempts.
Repeatable Response Process — The client now has a defined workflow for triaging future critical and high-severity alerts.
Reduced Manual Effort — Structured investigation steps reduce the time and effort needed per incident.
