Ignoring Checks

Ignoring Warnings

You may wish to ignore some warnings. If you'd like to do so, you can simply add a comment containing tfsec:ignore:<rule> to the offending line in your templates. If the problem refers to a block of code, such as a multiline string, you can add the comment on the line above the block, by itself.

For example, to ignore an open security group rule:

resource "aws_security_group_rule" "my-rule" {
    type = "ingress"
    cidr_blocks = [""] #tfsec:ignore:aws-vpc-no-public-ingress-sgr


resource "aws_security_group_rule" "my-rule" {
    type = "ingress"
    cidr_blocks = [""]

If you're not sure which line to add the comment on, just check the tfsec output for the line number of the discovered problem.

You can ignore multiple rules by concatenating the rules on a single line:

#tfsec:ignore:aws-s3-enable-bucket-encryption tfsec:ignore:aws-s3-enable-bucket-logging
resource "aws_s3_bucket" "my-bucket" {
  bucket = "foobar"
  acl    = "private"

Expiration Date

You can set expiration date for ignore with yyyy-mm-dd format. This is a useful feature when you want to ensure ignored issue won't be forgotten and should be revisited in the future.

Ignore like this will be active only till 2022-01-02, after this date it will be deactivated.

Workspace Ignores

Ignoring checks can be scoped to a workspace level. If you add the ws: declaration to your ignore it will only be honoured for that workspace.

# tfsec:ignore:AWS006:exp:2221-01-02 #tfsec:ignore:AWS018:ws:development
resource "aws_security_group_rule" "my-rule" {
    type        = "ingress"

    cidr_blocks = [""]

In the example above, when tfsec is run with the --workspace flag set to development, this ignore will be honoured, but otherwise will be disregarded.

tfsec --workspaces development .

Ignoring specific values

We have recently added support for ignoring based on the value that has been provided. This is particularly relevant when using for_each and you want to allow certain values.

locals {
  rules = {
    http = 80
    https = 443 

resource "aws_security_group_rule" "this" {
      for_each = local.rules
      type = "ingress"
      description     = "test"
      from_port       = each.value 
      to_port         = each.value
      protocol        = "tcp"
      cidr_blocks     = [""]


In the example above, the aws-vpc-no-public-ingress-sgr check will fail for 80 but when it creates the rule for 443 the check will pass.

This feature is experimental - while it works successfully, please raise issues through GitHub Issues
