About secret scanning

If someone checks a secret with a known pattern into a repository, secret scanning catches the secret as it's checked in, and helps you mitigate the impact of the leak. Repository administrators are notified about any commit that contains a secret, and they can quickly view all detected secrets in the Security tab for the repository. See About secret scanning.

Checking whether your license includes Advanced Security

You can identify if your enterprise has a license for Advanced Security by reviewing your enterprise settings. For more information, see Enabling GitHub Advanced Security for your enterprise.

Prerequisites for secret scanning

• The SSSE3 (Supplemental Streaming SIMD Extensions 3) CPU flag needs to be enabled on the VM/KVM that runs GitHub Enterprise Server. For more information about SSSE3, see Intel 64 and IA-32 Architectures Optimization Reference Manual in the Intel documentation.

• A license for GitHub Advanced Security (see GitHub Advanced Security license billing)

• Secret scanning enabled in the management console (see Enabling GitHub Advanced Security for your enterprise)

Checking support for the SSSE3 flag on your vCPUs

The SSSE3 set of instructions is required because secret scanning leverages hardware accelerated pattern matching to find potential credentials committed to your GitHub repositories. SSSE3 is enabled for most modern CPUs. You can check whether SSSE3 is enabled for the vCPUs available to your GitHub Enterprise Server instance.

1. Connect to the administrative shell for your GitHub Enterprise Server instance. See Accessing the administrative shell (SSH).

2. Enter the following command:

   grep -iE '^flags.*ssse3' /proc/cpuinfo >/dev/null | echo $?
   

   If this returns the value 0, it means that the SSSE3 flag is available and enabled. You can now enable secret scanning. See Enabling secret scanning below.

   If this doesn't return 0, SSSE3 is not enabled on your VM/KVM. You need to refer to the documentation of the hardware/hypervisor on how to enable the flag, or make it available to guest VMs.

Enabling secret scanning
