Skip Directories

Trivy traversals directories and scans all files except those matching the built-in allow rules by default. If your have a lot of files in your container image or project, the scanning takes time. To make it faster, you can skip traversal in the specific directory. Also, it would be helpful if your project contains secrets and certificates for testing.

$ trivy image --skip-dirs /var/lib --skip-dirs /var/log YOUR_IMAGE

$ trivy fs --skip-dirs ./my-test-dir --skip-dirs ./my-testing-cert/ /path/to/your_project

--skip-files also works similarly.

Filter by severity

Use --severity option.

$ trivy fs --severity CRITICAL ./

app/secret.sh (secrets)
=======================
Total: 1 (CRITICAL: 1)

+----------+-------------------+----------+---------+--------------------------------+
| CATEGORY |    DESCRIPTION    | SEVERITY | LINE NO |             MATCH              |
+----------+-------------------+----------+---------+--------------------------------+
|   AWS    | AWS Access Key ID | CRITICAL |   10    | export AWS_ACCESS_KEY_ID=***** |
+----------+-------------------+----------+---------+--------------------------------+

Filter by RuleID

Use .trivyignore.

$ cat .trivyignore

# Ignore these rules
generic-unwanted-rule
aws-account-id

Disable secret scanning

If you need vulnerability scanning only, you can disable secret scanning via the --scanners flag.

$ trivy image --scanners vuln alpine:3.15

With configuration file

trivy-secret.yaml in the working directory is loaded by default.

$ cat trivy-secret.yaml
rules:
  - id: rule1
    category: general
    title: Generic Rule
    severity: HIGH
    regex: (?i)(?P<key>(secret))(=|:).{0,5}['"](?P<secret>[0-9a-zA-Z\-_=]{8,64})['"]
allow-rules:
  - id: social-security-number
    description: skip social security number
    regex: 219-09-9999
  - id: log-dir
    description: skip log directory
    path: ^\/var\/log\/
disable-rules:
  - slack-access-token
  - slack-web-hook
disable-allow-rules:
  - markdown

# The following command automatically loads the above configuration.
$ trivy image YOUR_IMAGE

Also, you can customize the config file path via --secret-config.

$ cat ./secret-config/trivy.yaml
rules:
  - id: rule1
    category: general
    title: Generic Rule
    severity: HIGH
    regex: (?i)(?P<key>(secret))(=|:).{0,5}['"](?P<secret>[0-9a-zA-Z\-_=]{8,64})['"]
    allow-rules:
      - id: skip-text
        description: skip text files
        path: .*\.txt
enable-builtin-rules:
  - aws-access-key-id
  - aws-account-id
  - aws-secret-access-key
disable-allow-rules:
  - usr-dirs

# Pass the above config with `--secret-config`.
$ trivy fs --secret-config ./secret-config/trivy.yaml /path/to/your_project
