NAME

SSVC::Supplier - SSVC Supplier decision (patch development priority)

SYNOPSIS

use SSVC::Supplier;

$ssvc = SSVC::Supplier->new(
  exploitation      => 'active',
  automatable       => 'yes',
  value_density     => 'concentrated',
  technical_impact  => 'total',
  safety_impact     => 'catastrophic',
);

# Get the decision
say $ssvc->decision; # immediate

# Get the decision point value
say $ssvc->utility; # super_effective

# Convert SSVC in JSON in according of SSVC JSON Schema
$json = encode_json($ssvc);

DESCRIPTION

The Supplier decision helps a supplier (e.g. a software vendor) decide the priority with which to develop and release a patch, or other remediation, for a vulnerability.

Supplier

OBJECT-ORIENTED INTERFACE

$ssvc = SSVC::Supplier->new(%params)

Creates a new SSVC::Supplier instance using the provided decision points.

Parameters / Decision Points:

  • exploitation (required)

  • automatable (required), used to compute utility

  • value_density (required), used to compute utility

  • technical_impact (required)

  • safety_impact (required), used to compute public_safety_impact

  • utility (optional), Computed from automatable and value_density

  • public_safety_impact (optional), Computed from safety_impact

$ssvc->decision

The supplier patch-development priority decision: defer, scheduled, out_of_cycle or immediate.

$ssvc->TO_JSON

Helper method for JSON modules (JSON, JSON::PP, JSON::XS, Mojo::JSON, etc).

DECISION POINTS

$ssvc->exploitation

The present state of exploitation of the vulnerability.

$ssvc->automatable

Can an attacker reliably automate creating exploitation events for this vulnerability?

$ssvc->value_density

The concentration of value in the target.

$ssvc->technical_impact

The technical impact of the vulnerability.

$ssvc->safety_impact

The safety impact of the vulnerability.

$ssvc->utility

The usefulness of the exploit to the adversary, computed from automatable and value_density.

$ssvc->public_safety_impact

A coarse-grained representation of impact to public safety, computed from safety_impact.
