Business Challenge
The environment generated a range of critical and high-severity security alerts that needed fast, consistent handling.
01
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.
02
High-Stakes Alerts: Each alert type carried critical or high-severity impact if left unaddressed.
03
Manual Investigation Burden: Investigating and correlating each alert manually was slow and labor-intensive.
03 / 06
Solution
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.
04 / 06
Technology
The response process relied on Google Cloud's native security and networking tooling.
05 / 06
Results
The process gave the client faster, more consistent handling of security alerts.
01
Accelerated Log Monitoring: Faster review and correlation of security-relevant logs.
02
Stronger Security Enablement: Confirmed attacks were stopped through IP blocking and configuration changes.
06 / 06
Business Impact
The engagement gave the client a repeatable process for handling future intrusion attempts.
01
Repeatable Response Process: The client now has a defined workflow for triaging future critical and high-severity alerts.
02
Reduced Manual Effort: Structured investigation steps reduce the time and effort needed per incident.
