Improve alert triage, investigation, containment and recovery when suspicious activity appears.

How to Investigate a Suspicious Increase in Cloud API Calls

An API call spike can come from new automation, retries, a deployment loop, or unauthorized use of a credential. Checks to make Segment audit events by identity, action, resource, and time, then compare with deployment and job schedules. Check for unusual regions or permissions, preserve logs, and contain credentials through the response process if...

How to Investigate a Security Alert From a Shared Service Account

Shared service identities make it harder to attribute actions and distinguish automation from unauthorized use. Checks to make Identify the service owner and expected schedule, compare API or process activity with deployment records, and review credential usage and source hosts. Preserve logs and rotate or constrain credentials if activity cannot be...

How to Investigate a Sudden Disablement of Endpoint Security Policies

A policy may be disabled by an approved change, misconfiguration, agent failure, or unauthorized administrative action. Checks to make Check policy audit history, actor and approval, affected device scope, agent status, and related identity events. Restore protection using controlled change procedures and monitor for repeated policy changes. When to...

How to Investigate a Suspicious Increase in Failed API Authentication

Authentication failures may indicate expired credentials, a deployment error, abuse, or an attempted credential attack. Checks to make Group failures by key or identity, source, endpoint, and time; compare with credential rotations and deployment records; and look for successful use after the failures. Preserve logs and rotate or restrict credentials...

How to Investigate an Unexpected Change to a Cloud Backup Policy

A backup policy change may reduce protection, alter retention, or be part of an approved recovery adjustment. Checks to make Preserve the change event and actor, compare the policy with approved settings, and review related identity activity and backup jobs. Restore intended protection through a reviewed change and verify that new recovery points are...

How to Investigate a Sudden Loss of Security Log Ingestion

A gap in centralized logs can result from agent failure, credential expiry, network changes, storage limits, or a source-side configuration update. Checks to make Identify affected sources and the last received event, inspect forwarding and collector health, and compare source-local logs with central storage. Preserve local evidence, restore ingestion...

How to Investigate a Sudden Change in Cloud Storage Sharing Permissions

A permission change may broaden access through a direct grant, group membership, public link, or inherited folder setting. Checks to make Preserve the audit event, identify actor and affected objects, compare with approved changes, and review access or downloads after the change. Revert unauthorized grants through a controlled process and check related...

How to Investigate a Sudden Increase in Privileged Cloud Actions

A surge can reflect planned automation, an administrator task, or misuse of privileged credentials. Checks to make Group audit events by identity, action, resource, and source, compare with approved changes, and review sign-ins and role activation. Preserve evidence and verify the activity with the owner through a trusted channel before broad...
