Secure installation guide for DataSecurity Plus

Description

The DataSecurity Plus installation directory contains crucial files that enable it to start and stop, such as files containing database configuration information and the license file. The installation directory should be secured to prevent tampering, which could pose security risks, such as data theft, sensitive data exposure, and operational risks, and potentially render the product dysfunctional and unusable. By default, DataSecurity Plus will be stored in the C:\Program Files\ManageEngine\DataSecurity Plus folder, which grants Full Control access to non-admin users in the Authenticated Users group for the files and folders located in the DataSecurity Plus installation directory and allows content modification. To prevent this from happening, implement the measures below based on your DataSecurity Plus installation build.

Note: Removing Authenticated Users from the access control list (ACL) won't help, as this will render them unable to start DataSecurity Plus as a service or application.

Solution

To overcome unauthorized access to the DataSecurity installation directory, follow the steps below, based on the build version.

1. For new DataSecurity Plus installations, builds 6126 and above

ⅰ For new installations of builds 6126 and above, only the following users and groups are provided with access to the installation directory to ensure file security and integrity:

  • Local system account
  • User account used for DataSecurity Plus installation
  • Administrators group
  • Domain Admins group

ⅱ Permissions are removed for the following groups and users:

  • CREATOR OWNER
  • BUILTINUSERS
  • Authenticated users
  • ALL APPLICATION PACKAGES
  • ALL RESTRICTED APPLICATION PACKAGES

ⅲ By default, inheritance will be disabled for the DataSecurity Plus folder.

Note: If the product is installed as a service, right-click ManageEngine DataSecurity Plus in the Windows Services application. Click Properties > Logon and make sure that the account configured has been assigned Full Control permission for the installation directory.

2. For existing DataSecurity Plus installations, lower than build 6126

Note: The below instructions are applicable only for users who have installed DataSecurity Plus before 6126 build and have upgraded to the latest version by applying service pack.

Unauthorized users can be prevented from accessing the DataSecurity Plus installation directory in two ways:

  1. Run the setAppPermission.bat file
  2. Modify the required permissions manually

I. Run the setAppPermission.bat file

With this method, access to the installation directory is automatically restricted to only the necessary accounts. There are two ways to do this:

Option 1: Update to build 6126 or above. Navigate to the <Installation Directory>/bin folder (by default, C:\Program Files\ManageEngine\DataSecurity Plus\bin) and run the setAppPermission.bat file using the elevated Command Prompt.

Option 2: Download the zip file from this link. Extract the zip and move setAppPermission.bat to the <Installation Directory>/bin folder. Run the setAppPermission.bat file using the elevated Command Prompt.

Run the setAppPermission.bat file

II. Modify the required permissions manually

To modify access permissions on the DataSecurity Plus installation directory for unnecessary groups and user accounts manually, follow the steps below:

  • Disable inheritance for the installation directory (by default, C:\Program Files\ManageEngine\DataSecurity Plus). Refer to the Appendix for step-by-step instructions.
  • Remove access permissions for all unnecessary groups. Refer to the Appendix for step-by-step instructions.
  • Provide Full Control permissions to the Local System Account and the Administrators Group for the product's installation directory. Refer to the Appendix for step-by-step instructions.
  • Provide Modify permissions to the Domain Admins group for the product's installation directory. Refer to the Appendix for step-by-step instructions.
  • Assign Full Control permission to users who can start or stop the product. Refer to the Appendix for step-by-step instructions.
  • If the product is installed as a service, right-click ManageEngine DataSecurity Plus in the Windows Services application. Click Properties > Logon and make sure that the account configured has been assigned Full Control permission for the installation directory.
Note:
  • Microsoft recommends that software be installed in the Program Files directory. Based on your specific needs or organizational policies, you can choose a different location.
