When managing applications deployed via Helm, the standard and most effective way to perform updates, especially rolling updates, is through 'helm upgrade'. By modifying the 'image.tag' value in the Helm chart (either directly in 'values.yamr or via '-set' as shown), Helm will intelligently detect the change and perform a rolling update on the Kubernetes deployment, ensuring zero downtime if the deployment strategy is set to 'RollingUpdate' (which is the default for most Helm charts). Options A, B, D, and E are either less appropriate for a Helm-managed application, cause downtime, or are not the primary mechanism for an image update through Helm.

Option B best aligns with the principle of least privilege. XSIAM offers built-in roles, but for granular control, custom roles are often necessary. Level 1 Analysts only need view access, which can be achieved with specific view permissions. Level 2 Incident Responders need modify and enrichment capabilities, requiring more advanced permissions. SOC Managers, with full administrative control, would typically be assigned the 'Administrator' role or a custom role with equivalent broad permissions. Using 'Super Administrator' for SOC Managers might grant more power than strictly necessary for day-to-day operations, potentially violating least privilege. Option D's 'Security Operations Center - Admin' for Level 2 is too broad. Options A, C, and E incorrectly map the built-in roles to the specified requirements.

Both B and E represent best practices for secure credential management with SaaS applications. Option B (IdP/OAuth) is ideal if supported by the SaaS application, as it provides a robust, token-based, and often MFA-aware authentication mechanism without storing static credentials in XSIAM. Option E (secrets management solution) is crucial for securely storing and distributing sensitive credentials like API keys, ensuring they are not hardcoded or exposed and can be rotated automatically. Option A is a basic approach but less secure than E. Option C is impractical and prone to errors. Option D addresses network access but not credential management itself.

To enforce a consistent, structured input for 'Investigation Status' and 'Resolution Notes' within XSIAM high-severity incidents, the optimal approach involves creating custom fields as 'Picklist' or 'Enum' types. This restricts input to predefined values, ensuring consistency. Furthermore, integrating XSIAM playbooks with 'Form Tasks' allows for conditionally requiring these fields to be populated at specific incident lifecycle stages (e.g., before closing an incident), enforcing the desired workflow and data quality. Options A, B, D, and E are either unstructured, create unnecessary complexity, or rely on external systems/manual adherence.

To effectively detect renamed PsExec, a multi-faceted approach is required: A: This is a highly effective field because it often stores the original filename embedded in the executable's metadata, regardless of renaming. This is a primary and very strong indicator. B: Leveraging known hashes from threat intelligence is critical for catching specific malicious variants, including renamed ones. This provides a direct match to known bad. D: Behavioral Rule: While the question focuses on 'indicator rules', for advanced threats like PsExec, behavioral detection is superior. PsExec has distinct behavioral patterns (SMB/IPC$ connections, specific service creation). A behavioral rule can detect these underlying actions irrespective of the executable name. E: 'regex' on PsExec's command-line arguments often follow predictable patterns (e.g., targeting administrative shares 'ADMINS or 'CS). Using regex to match these patterns can detect PsExec activity even when the executable itself is renamed. Option C is less reliable; attackers often ensure the command line doesn't expose the original name. While sometimes useful, it's not as robust as the other options for renamed executables.
