Cisco Configuration Anonymizer

Netconan is an interesting Github project to remove sensitive information from Network configuration files. This is particularly useful in managed SP environment where we share configurations with the end-customer, usually in form of an LLD or SLD.
Netconan can anonymize many types of sensitive information:

  • Sensitive strings like passwords or SNMP community strings for many common network vendors.
  • IPv4 and IPv6 addresses
  • User-specified sensitive words
  • User-specified AS numbers

Netconan is maintained by the same company as Batfish, an interesting open source modeling tool.
