These data nodes may be considered sensitive or vulnerable in some network environments.

For example, adding OSPF on any unprotected interface could allow an OSPF adjacency to be formed with an unauthorized and malicious neighbor. Once an adjacency is formed, traffic could be hijacked. As a simpler example, aDenial-of-ServiceDoS attack could be mounted by changing the cost of an OSPF interface to be asymmetric such that a hard routing loop ensues. In general, unauthorized modification of most OSPF features will posetheretheir own set of securityrisks and the "Security Considerations"risks. The Security Considerations sections in the respective reference RFCs should be consulted.</t> <t>Some of the readable data nodes inthe ietf-ospf.yangthis YANG module may be considered sensitive or vulnerable in some network environments.

Additionally, in the case of an area LSDB, the complete IP network topology and, if deployed, thetraffic engineeringTE topology of the OSPF area can bereconstucted.reconstructed. Network operators may consider their topologies to be sensitive confidential data.</t> <t>For OSPF authentication, configuration is supported via the specification ofkey-chainskey chains <xreftarget="RFC8177"/>target="RFC8177" format="default"/> or the direct specification of a key and an authentication algorithm.
