How To Check Cipher Suites In Windows Server?

Cipher suites are a crucial element for ensuring secure communication over the network. In Windows Server, it is essential to regularly check cipher suites to ensure that the server is using the most secure options available. This article will guide you through the process of checking cipher suites in Windows Server. By following these steps, you can ensure that your server is using strong encryption algorithms to protect your data.

Step 1: Open the Local Security Policy

To begin the process of checking cipher suites in Windows Server, you need to open the Local Security Policy. Follow these steps:

  1. Press the Windows key + R to open the Run dialog box.
  2. Type “secpol.msc” and press Enter.
  3. The Local Security Policy window will open.

By opening the Local Security Policy, you gain access to various security settings of your Windows Server.

Step 2: Navigate to the Cipher Suites Settings

Now that you have the Local Security Policy window open, you need to navigate to the cipher suites settings. Follow these steps:

  1. In the left-hand pane of the Local Security Policy window, expand the “Local Policies” section.
  2. Select the “Security Options” option.
  3. In the right-hand pane, scroll down until you find the “System cryptography: Use FIPS 140 compliant cryptographic algorithms, including encryption, hashing, and signing algorithms” setting.

This setting controls the cipher suites used by Windows Server.

Step 3: View the Enabled Cipher Suites

To view the enabled cipher suites in Windows Server, you need to open the properties of the “System cryptography: Use FIPS 140 compliant cryptographic algorithms, including encryption, hashing, and signing algorithms” setting. Follow these steps:

  1. Double-click the “System cryptography: Use FIPS 140 compliant cryptographic algorithms, including encryption, hashing, and signing algorithms” setting.
  2. A window with the setting’s properties will open.
  3. Look for the “Enabled” cipher suites.

The enabled cipher suites are the ones that Windows Server is currently using for encryption.

Step 4: Check the Strength of the Cipher Suites

Once you have identified the enabled cipher suites, it is important to verify their strength. The strength of a cipher suite is determined by the encryption algorithms and key lengths it uses. To ensure optimal security, it is recommended to use cipher suites that employ strong encryption algorithms and longer key lengths. Here are some common algorithms to look for:

  • AES (Advanced Encryption Standard)
  • 3DES (Triple Data Encryption Standard)
  • SHA-2 (Secure Hash Algorithm 2)
  • ECDHE (Elliptic Curve Diffie-Hellman Ephemeral)

If you find any weak cipher suites, it is advisable to disable them and only keep the strong ones enabled.

Step 5: Update Cipher Suites if Necessary

If you discover that your Windows Server is not using the most secure cipher suites or if there are weak cipher suites enabled, it is crucial to update them. Here’s how:

  1. Download and install the latest updates for your Windows Server.
  2. Apply any security patches and fixes provided by Microsoft.
  3. Regularly check for updates and keep your server up to date to ensure the latest security improvements.

By updating your Windows Server, you guarantee that it has the latest cipher suites with enhanced security.
