1. A computer implemented method, comprising:
identifying, by a number of processor units, a number of certificates for a device within a network to obtain a file path for each certificate;
performing, by the number of processor units, an internal scan of the device to obtain a port number for each active port associated with network protocol on the device;
identifying, by the number of processor units, a certificate chain associated with each port number based on the network protocol for the device;
comparing, by the number of processor units, content for each certificate from the number of certificates to the certificate chains for the device to generate a number of matches; and
generating, by the number of processor units, a data structure comprising the file path of the certificate for each port on the device based on the number of matches.
