Use Cases

Common use cases for Cortex XSOAR, including analytics and siem, authentication, case management, data enrichment, threat intelligence, forensic and malware,
This section includes common Use Cases for the different categories of Cortex XSOAR integrations. While this list is not meant to be exhaustive, it's a good starting point for you to understand what use cases could be supported by your integration.

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)
This will normally include the Fetch Incidents possibility for the instance. It can also include list-incidents or get-incident as integration commands, or important information for an Event/Incident.
Analytics & SIEM Integration Example: ArcSight ESM

Authentication

Top Use Cases:
  • Use credentials from the authentication vault in order to configure instances in Cortex XSOAR. (Save credentials in:
    Settings
    Integrations
    Credentials
    .) The integration should include the isFetchCredentials parameter, and other integrations that will use credentials from the vault, should have the ‘Switch to credentials’ option.
  • Lock/Delete Account – Give option to lock account (credentials), and unlock/undelete
  • Reset Account - Perform a reset password command for an account
  • List credential names – Do not post the actual credentials. (For example – Credential name: McAfee ePO, do not show actual username and password.)
  • Lock Vault – In case of an emergency (if the vault has been compromised), allow the option to lock + unlock the whole vault
  • 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/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

Data Enrichment & Threat Intelligence

Top Use Cases:
  • Enriching information about different IOC types: Upload object for scan and get the scan results. (If there’s a possibility to upload private/public, the default should be set to private.) Search for former scan results about an object. (This way you can get information about a sample without uploading it yourself.) Enrich information and scoring for the object.
  • Add/Search for indicators in the system
  • Add indicators to the exclusion list
  • Calculate DBot Score for indicators
Data Enrichment & Threat Intelligence Integration Example: VirusTotal

Email Gateway

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 (The gateway can place suspicious messages on hold, and sometimes they would need to be released to the receiver.)
Email Gateway Integration Example: MimeCast

Endpoint

Top Use Cases:
  • Fetch Incidents & Events
  • Get event details (from specified incident)
  • Quarantine 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 server
  • 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
Sandbox Integration Example: Cuckoo Sandbox

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: Palo Alto Networks PAN-OS

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
