Define Vulnerability

A vulnerability is a weakness or flaw in a software or hardware component that can be exploited by attackers to compromise confidentiality, integrity, or availability.

Before you begin

Role required: sn_sec_tisc.analyst

Procedure

  1. Navigate to Workspaces > Threat Intelligence Security Center.

  2. Select Threat Intel Library icon on the workspace.

  3. Go to Vulnerability object.

  4. Select New.

    Note:

    When you create a record for an observable, indicator, entity, or object, a corresponding source record is automatically generated. A confirmation message is displayed to indicate that the new object record is created, and you’re then redirected to the aggregated record.

  5. On the form, fill in the fields.

FieldDescription
NameA name used to identify the Vulnerability.
DescriptionA description that provides more details and context about the vulnerability, potentially including its purpose and its key characteristics.
CVE IDThe Common Vulnerabilities and Exposures identifier for this vulnerability.
CVE Published DateIndicates when the vulnerability is published. Note: This field can only be set if there is a CVE ID field value set.
CNA \(CVE Naming Authority\)The CVE Naming Authority responsible for assigning the CVE ID.
CNA Last ModifiedIndicates when the record was last modified.
Risk RatingIndicates the normalized degree of severity of this vulnerability.- Critical - High - Medium - Low
Vulnerability ClassThe classification category identifies the type of vulnerability and serves as a reference field for organizing vulnerabilities.The available options for this field are managed in the `sn_sec_tisc_vulnerability_class` table, enabling you to define and maintain vulnerability class selections as required.
Threat LevelThreat level refers to the probability of a threat occurring. The purpose of this field is to help the security teams assess and prioritize the observables based on their importance and potential impact.Note: The value in this field is automatically populated only if the threat intelligence source supports the threat level. For example, if Threat Level = High (then the threat occurrence is widespread and a persistent threat).
Threat SeverityThreat severity refers to the impact that the threat would have if it did occur. The purpose of this field is to help the security teams assess and prioritize the observables based on their importance and potential impact.Note: The value in this field is automatically populated only if the threat intelligence source supports the threat severity. For example, if Threat Severity = Critical (then it could cause immediate harm).
TLPTLP is used to confirm that sensitive information is shared with the appropriate audience.The following are the TLP values: - AMBER - AMBER+STRICT - CLEAR - GREEN - RED
ConfidenceEnter the confidence for this observable record.The confidence property identifies the confidence that the creator has in the correctness of their data. The confidence value must be a number in the range of 0-100.
Affected SoftwareLists the affected software associated with the vulnerability.
SeverityIndicates the normalized degree of severity of this vulnerability

  1. Select Save.

    After you save, a prompt message is displayed indicating that A new observable record is created. Select Continue to edit the record and create new relationships.

  2. Select Continue.

    you will be taken to the form view of the aggregated vulnerability record.

    Important:

    • Zero Day Status Toggle: You can toggle the Zero Day status directly from the status pill in the header of the vulnerability record form. TISC supports zero-day vulnerabilities which are newly discovered security flaws without an assigned CVE identifier or remediation. These records may include an internal organizational identifier. As a zero-day vulnerability evolves, it can transition to a known CVE once an official identifier is assigned and remediation guidance is published.

      These records can include an internal organizational identifier. Over time, a zero-day vulnerability can transition to a known CVE after official identifier is assigned and remediation guidance is published.

      • By default, fields such as CVE ID and CVE Published Date remain empty.
      • An internal organizational identifier can be added in the Identifiers related records.
      • To enable or disable zero-day status, use the Zero-Day toggle button on the vulnerability record page, which marks or unmarks the vulnerability as a zero-day.
      • For manually created vulnerability source records, a dedicated Zero Day field is also available on the source record form.
        • Remediations Count: The form includes a Remediations Count field, which indicates the total number of remediations linked to the vulnerability. To view or manage these remediations, go to the Related Records tab and select the Remediations section.
        • Prevent System Updates: The form includes a Prevent System Updates check box. By selecting this option, you ensure that any updates made by analysts are retained, while system-generated updates are prevented. |Field|Description| |-----|-----------| |TISC Tags| |Select Tags|Select the tags that are associated with the vulnerability.| |Add Tags|Add new tags.| |Taxonomies| |Select Taxonomy|Select a Taxonomy that is associated with this vulnerability.| |Add Taxonomy Values|Add Taxonomy values that are associated with this vulnerability.|

    Note: TISC Tags & Taxonomies appears after you save the vulnerability record. You can add tags and taxonomies for an existing record.

    Add TISC tags to a Vulnerability record from the list view:

    • Select Add TISC Tags to associate the tags to the vulnerability record from the list view.
    • Search and select the desired tag.
    • Select Submit to add the tag.

      A confirmation displays indicating that the tags are applied successfully.

    Add Vulnerability record to a case from the list view:

    • Select Add to Case to add the vulnerability record to a case.
    • Select the case(s).
    • Select Add to add the case to the vulnerability record.

      The record is added to case(s) successfully.

  3. If you want to delete any record then, select Delete to delete the aggregated record.

    When you select this action, then it will remove all the related records, except the original source data, and trigger re aggregation.

    Note:

    A confirmation message appears to verify that you want to delete the aggregated record. To also delete the associated source records and prevent re-aggregation, select the Delete Source Records check box. This action permanently removes all the related source records.
