Home Network Administration Protocol (HNAP) is a proprietary network protocol invented[1] by Pure Networks, Inc. and acquired by Cisco Systems which allows identification, configuration, and management of network devices. HNAP is based on SOAP.[2]

Starting in January 2010, vulnerabilities were discovered in multiple D-Link network devices where HNAP authentication could be bypassed.[3][4][5]

2014 HNAP is used by "The Moon" worm which infects Linksys routers.[6]
