bedrock agent and action group changes are common during legitimate development, prompt tuning, and ci/cd deployments. verify whether the user identity, user agent, and/or source ip should be modifying agents in your environment, and confirm a corresponding change request exists. automation roles (iac pipelines, deployment tooling) may routinely call these apis and can be exempted from the rule if they generate false positives.	t1505 aws elastic

developers or administrators creating bedrock agents interactively using personal iam user credentials. this is the intended detection surface — validate the identity against known developer accounts and confirm the agent configuration (instruction, action groups, model) matches a known project.	t1505 aws elastic
false positives are expected to be very rare due to the specific nature of this rule. legitimate application deployments typically do not involve multipart form uploads to .action endpoints followed immediately by jsp file creation in webapps directories. however, custom deployment scripts or automated testing tools that simulate file uploads could potentially trigger this alert. review the source ip, user agent, uploaded file content, timing, and deployment schedules to validate if the activity is authorized. standard package manager operations are already excluded from detection.	t1105 t1190 t1505 linux elastic
files generated during installation will generate a lot of noise, so the rule should only be enabled after the fact.	t1190 t1210 t1505 windows elastic

legitimate platform, ml, or application teams may associate or update knowledge bases on bedrock agents as part of normal development, onboarding, or rag pipeline changes. verify that the actor identity, user agent, and source ip correspond to expected automation or authorized engineers, and that the associated knowledge base is an approved, organization-owned resource. if known behavior is causing false positives, it can be exempted from the rule.	t1505 aws elastic
