Discover a Certificate: Subnet

To discover a certificate by subnet:
  1. Click and select CERT+ > Certificate Discovery.
  2. Under Certificate Discovery, click Discovery and select Unauthenticated.
  3. On the Add Discovery page, under the Discover Details section, select On-demand or Schedule.
    On selecting On-demand discovery, AppViewX will trigger the discovery certificates process for that instance.
    Note: You can also upload the following details to the template in the .csv, .xls, or .xlsx format.
  4. Enter the Discovery Name and Description in the respective fields.
  5. Under the Discover By section, in the Source field, select Subnet from the dropdown.
  6. Network: You can enter the network details in this field.
  7. Subnet Split Level: Based on this value, the provided subnet will be split into multiple batches for the discovery process.
  8. Ports: You can enter any port number from 0 to 65535. You can separate port ranges with a hyphen (For example, 444-666, 888-999, 922, 44). You can also select All Ports to include port numbers from 0 to 65535.
  9. Datacenter (of AppViewX agent): You can select the datacenter of the AppViewX agent from this drop-down list.
    SNI Hostname(s): AppViewX will discover the certificates based on the hostnames against the IP address. Multiple hostname values are supported by using the comma (,) as a delimiter.
    • Scan Type: There are two scan types in this option:
      • Aggressive: AppViewX will discover the certificates from all IPs and ports based on the provided values, irrespective of the previous discovery details.
      • Passive: AppViewX will discover the certificates only from the IPs and ports from which the certificates are discovered previously.
    • Batch Execution Type: Multiple batches will be run either parallel or sequentially. You can choose between parallel and sequential execution.
      • Sequential Execution: AppViewX will take and execute the batches one by one. The interval between the batches can also be defined.
      • Parallel Execution: AppViewX will take the number of batches based on the infrastructure capability and the discovery process will be executed for those number of batches in parallel.
