Abstract

Common use cases for Cortex XSOAR, including analytics and siem, authentication, case management, data enrichment, threat intelligence, forensic and malware,

The following are common use cases for the different categories of Cortex XSOAR integrations. While this list is not meant to be exhaustive, it's a starting point to understand what use cases are supported by Cortex XSOAR and third-party integrations.

Analytics and SIEM

Top use cases:

  • Fetch incidents with relevant filters.

  • Create, close and delete incidents/events/cases.

  • Update incidents - update status, assignees, severity, SLA, etc.

  • Get events related to an incident/case for enrichment/investigation purposes.

  • Query SIEM (consider aggregating logs).

Note

These integrations usually include the Fetch Incidents option for an instance. It can also include list-incidents or get-incident as integration commands, or important information for an event or incident.

Analytics & SIEM Integration Example: ArcSight ESM

Authentication

Top use cases:

  • Use credentials from the authentication vault to configure instances in Cortex XSOAR. (Save credentials in: Settings & InfoSettingsIntegrationsCredentials.) The integration should include the isFetchCredentials parameter. Integrations that use credentials from the vault should have the Switch to credentials option.

  • Lock/Delete Account – Use an integration to lock/unlock a third-party account.

  • Reset Account - Perform a reset password command for a third-party account.

  • Lock an external credentials vault - in case of emergency (if the vault has been compromised), allow the option to lock/unlock the entire vault via an integration.

  • Step-Up authentication - Enforce Multi Factor Authentication for an account.

Authentication Integration Example: CyberArk AIM

Case Management

Top use cases:

  • Create, get, edit, close a ticket or issue, add + view comments.

  • Assign a ticket/issue to a specified user.

  • List all tickets, filter by name, date, assignee.

  • Get details about a managed object, update, create, delete.

  • Add and manage users.

Case Management/Ticketing integration example: ServiceNow V2

Data Enrichment & Threat Intelligence

Top use cases:

  • Enrich information about different IOC types: Upload object for scan and get the scan results. (If there’s an option to upload private/public, the default should be set to private.) Search for former scan results about an object to get information about a sample without uploading it yourself. Enrich information and scoring for the object.

  • Add indicators to the system and search for existing indicators.

  • Add indicators to the exclusion list.

  • Calculate DBot Score for indicators.

  • Enrich asset – get vulnerability information for an asset (or a group of assets) in the organization.

  • Generate/trigger a scan on specified assets.

  • Get a scan report including vulnerability information for a specified scan and export it.

  • Get details for a specified vulnerability.

  • Scan assets for a specific vulnerability.

Data Enrichment & Threat Intelligence Integration Example: Unit 42 Objects Feed.

Email

Top use cases:

  • Get message – download the email itself, retrieve metadata, body.

  • Download attachments for a given message.

  • Manage senders – block/allow specified mail senders.

  • Manage URLs – block/allow the sending of specified URLs.

  • Encode/decode URLs in messages

  • Release a held message when a gateway has placed a suspicious message on hold.

Email Gateway integration example: MimeCast

Endpoint

Top use cases:

  • Fetch incidents & events.

  • Get event details (from specified incident).

  • Quarantine a file.

  • Isolate and contain endpoints.

  • Update indicators (network, hashes, etc.) by policy (can be block, monitor) – deny list.

  • Add indicators to the exclusion list.

  • Search for indicators in the system (Seen indicators and related incidents/events).

  • Download file based on hash, path.

  • Trigger scans on specified hosts.

  • Update .DAT files for signatures and compare existing .DAT file to the newest one on the Cortex XSOAR tenant.

  • Get information for a specified host (OS, users, addresses, hostname).

  • Get policy information and assign policies to endpoints.

Endpoint integration examples: Cortex XDR, Tanium and Carbon Black Protection

Forensics and Malware Analysis

Top use cases:

  • Submit a file and get a report (detonation).

  • Submit a URL and get a report (detonation).

  • Search for past analysis (input being a hash/URL).

  • Retrieve a PCAP file.

  • Retrieve screenshots taken during analysis.

Forensic and Malware Analysis example: Cuckoo Sandbox

IAM (Identity and Access Management)

Top use cases:

  • Create, update, and delete users.

  • Manage user groups.

  • Block users, force change of passwords.

  • Manage access to resources and applications.

  • Create, update, and delete roles.

Network Security (Firewall)

Top use cases:

  • Create block/accept policies (source, destination, port), for IP addresses and domains.

  • Add addresses and ports (services) to predefined groups, create groups, etc.

  • Support custom URL categories.

  • Fetch network logs for a specific address for a configurable time frame.

  • URL filtering categorization change request.

  • Built-in blocked rule command for fast-blocking.

  • If there is a Management FW, allow the option to manage policy rules through it.

Network Security Firewall Integration example: Tufin (Partner Contribution)

Network Security (IDS/IPS)

Top use cases:

  • Get/fetch alerts.

  • Get PCAP file, packet.

  • Get network logs filtered by time range, IP addresses, ports, etc.

  • Create/manage/delete policies and rules.

  • Update signatures from an online source / upload + get last signature update information.

  • Install policy (if existing).

Network Security (IPS/IDS) Integration Example: ProtectWise

Vulnerability Management

Top use cases:

  • Enrich asset – get vulnerability information for an asset (or a group of assets) in the organization.

  • Generate/trigger a scan on specified assets.

  • Get a scan report including vulnerability information for a specified scan and export it.

  • Get details for a specified vulnerability.

  • Scan assets for a specific vulnerability.

Vulnerability Management integration example: Tenable.io
