By default, ThreadFix installs with a database deployed inside a container with the appropriate values already set. The following instructions cover installation of ThreadFix with an external database or other advanced database configurations.

Prerequisites

Audience: IT Professional
Difficulty: Intermediate
Time needed: Approximately 25 minutes
Tools required: SQL Server Management Studio or Kubernetes cluster with mssql-tools container

Requirements:

• Microsoft SQL Server >= 2017

• FQDN or IP for the SQL server

• Account with Administrative access to SQL Server

• Account with permissions to modify SQL Server configuration

Helm installations are configured with yaml files that override default properties. The following examples would need to be invoked with the command -f .yaml appended to the helm installation command. For example, if the yaml file is namedappsec-db.yaml, invoke with ‘helm install tf denimgroup/threadfix -f appsec-db.yaml.

Configuring External AppSec Database

The following properties must be set for the database to function correctly. Consult vendor guides for how to properly set these values.

1. Log into SQL Server

   1. If SQL Server Management studio is installed, it may be run directly

   2. If SQL Server Management Studio CLI is not installed, the ThreadFix Kubernetes cluster may be leveraged to run the SQL Server CLI

      kubectl run -it --restart=Never --rm=true --image=mcr.microsoft.com/mssql-tools mssql-tools -- /bin/bash
      When a bash prompt appear, run the MySQL CLI (replace values in angle brackets, <> with their appropriate value)
      sqlcmd -U <user> -S <hostname>
      

2. Create the ThreadFix database.

   Code Block
   CREATE DATABASE threadfix; GO

3. Set the following values for the ThreadFix database.

   Code Block
   ALTER DATABASE threadfix SET READ_COMMITTED_SNAPSHOT ON GO ALTER DATABASE threadfix SET ALLOW_SNAPSHOT_ISOLATION ON GO

4. Create the ThreadFix user (replace values in angle brackets, <> with appropriate values).

   Code Block
   CREATE LOGIN ThreadFix WITH PASSWORD = '<threadfix-user-password>'; GO

5. Grant access to the ThreadFix user.

   Code Block
   USE threadfix; GO CREATE USER ThreadFix FOR LOGIN ThreadFix; GO exec sp_addrolemember 'db_owner', 'ThreadFix'; GO

6. Exit SQL Server.

Create External Database Helm Values

To review the pre-requisites for hosting an SQL Server ThreadFix database externally, please refer to the Windows SQL Server Configuration guide.

1. Create two files, username.txt and password.txt, containing the username and password credentials respectively for the external database.

   • Warning: The external database must already contain the database threadfix, and the username and password configured above must be granted ownership permissions on that database.

   • Warning: Many text editing tools insert a trailing newline character, \n, to text files by default. If the text editor being used has this property, consult the documentation on how to disable this functionality.
     

2. Validate no newline characters have been added to the username and password files. The following should output 0 for both files.

   Code Block
   wc -l username.txt password.txt

3. Create a kubernetes secret for the external database:

   Code Block
   kubectl create secret generic db-user-pass --from-file=username=./username.txt --from-file=password=./password.txt

4. Remove the previously created files.

   Code Block
   rm username.txt rm password.txt

5. Set the FQDN or IP of the database (replace <hostname> with the FQDN or IP of the database):

   Code Block
   DB_HOSTNAME=<hostname>

6. Set the name of the ThreadFix database (default threadfix).

   Code Block
   DB_NAME=<db_name>

7. Create myValues folder (if it does not exist).

   Code Block
   mkdir -p myValues

8. Create appsec-db.yaml.

   Code Block

   echo "appsec: db: type: sqlserver existingSecret: db-user-pass globallyQuoted: true hostnameOverride: $DB_HOSTNAME database: $DB_NAME auth: db: type: sqlserver existingSecret: db-user-pass globallyQuoted: true hostnameOverride: $DB_HOSTNAME database: $DB_NAME ## 3.1 only appsecdata: db: type: sqlserver existingSecret: db-user-pass globallyQuoted: true hostnameOverride: $DB_HOSTNAME database: $DB_NAME appsecimporter: db: type: sqlserver existingSecret: db-user-pass globallyQuoted: true hostnameOverride: $DB_HOSTNAME database: $DB_NAME appsecvip: db: type: sqlserver existingSecret: db-user-pass globallyQuoted: true hostnameOverride: $DB_HOSTNAME database: $DB_NAME queue: db: type: sqlserver existingSecret: db-user-pass globallyQuoted: true hostnameOverride: $DB_HOSTNAME database: $DB_NAME jobcoordinator: db: type: sqlserver existingSecret: db-user-pass globallyQuoted: true hostnameOverride: $DB_HOSTNAME database: $DB_NAME " > myValues/appsec-db.yaml

9. Finish any other tasks from the Installation Checklist , then Install with Helm.
