ParameterDescription

DescriptionA brief explanation explaining the Alert
Custom Fields (JSON Format)Add a Custom Field in JSON format. Please note that this applies only if you have manually added a custom record column to the subject table.

Advanced- Default SeverityAssigned severity rank used when no specific severity has been set. If a severity value is is null or the value provided but does not match any mapping or recognized Blink severity levels, the default severity will be used instead.
Advanced- Low Severity MappingA comma-separated list of vendor-specific severity values that map to Blink’s Case Management’s Low severity level.
Advanced- Medium Severity MappingA comma-separated list of vendor-specific severity values that map to Blink’s Case Management’s Medium severity level.
Advanced- High Severity MappingA comma-separated list of vendor-specific severity values that map to Blink’s Case Management’s High severity level.
Advanced- Critical Severity MappingA comma-separated list of vendor-specific severity values that map to Blink’s Case Management’s Critical severity level.

Mapping Alert Severity to Blink’s System

Different security tools often report severity using their own scales—numeric values, labels, or custom levels. To ensure consistent prioritization in Blink, you can map these varying severity values, in the advanced settings of the Create Alert action, to Blink’s standardized severity levels (Low=1, Medium=2, High=3, Critical=4). For Example: Example Payload: 
{
  "id": "ind:bc44a7a3e758465f857867dcf4ac8c17:565469335361356727",
  "name": "FalseExecutableExtension",
  "description": "An executable was run with a contradicting file extension",
  "cmdline": "./whoami.rtf",
  "filename": "whoami.rtf",
  "filepath": "/Users/wilder/whoami.rtf",
  "alleged_filetype": "rtf",
  "platform": "Mac",
  "os_version": "Monterey (12)",
  "hostname": "DT-BART-SIMPSON",
  "user_name": "sam.gamgee",
  "md5": "32ff28d4fdb4b244c355d7f8378fa2b1",
  "sha256": "8d3f68b16f0710f858d8c1d2c699260e6f43161a5510abb0e7ba567bd72c965b",
  "severity": 50,
  "tactic": "Defense Evasion",
  "technique": "Masquerading",
  "timestamp": "2024-07-24T15:25:00Z",
  "falcon_host_link": "https://falcon.us-2.crowdstrike.com/activity-v2/detections/..."
}
In the Severity Parameter: The incoming alert payload specifies a severity of 50.
In Advanced Settings: A severity value of 50 is mapped to Blink’s High severity level, which corresponds to a severity rank of 3 in the output.You can customize these mappings to ensure external alert severity levels align with your internal triage and prioritization standards.
Blink’s severity levels are ranked as:
  • Low = 1
  • Medium = 2
  • High = 3
  • Critical = 4
