For OSPF, the ability to modify OSPF configuration will allow the
entire OSPF domain to be compromised including peering with
unauthorized routers to misroute traffic or mount a massive Denial-
of-Service (DoS) attack. 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, a Denial-of-Service
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 pose there own
set of security risks and the "Security Considerations" in the
respective reference RFCs should be consulted.
Some of the readable data nodes in the ietf-ospf.yang module may be
considered sensitive or vulnerable in some network environments. It
is thus important to control read access (e.g., via get, get-config,
or notification) to these data nodes. The exposure of the Link State

id]/database
/ospf/areas/area[area-id]/interfaces/interface[name]/database
/ospf/area/area[area-id]/sham-links/sham-link[local-id remote-
id]/database
Exposure of the Link State Database includes information beyond the
scope of the OSPF router and this may be undesirable since exposure
may facilitate other attacks. Additionally, in the case of an area
LSDB, the complete IP network topology and, if deployed, the traffic
engineering topology of the OSPF area can be reconstucted. Network
operators may consider their topologies to be sensitive confidential
data.
For OSPF authentication, configuration is supported via the For OSPF authentication, configuration is supported via the
specification of key-chains [RFC8177] or the direct specification of specification of key-chains [RFC8177] or the direct specification of
key and authentication algorithm. Hence, authentification key and authentication algorithm. Hence, authentication
configuration using the "auth-table-trailer" case in the configuration using the "auth-table-trailer" case in the
"authentication" container inherits the security considerations of "authentication" container inherits the security considerations of
[RFC8177]. This includes the considerations with respect to the [RFC8177]. This includes the considerations with respect to the
local storage and handling of authentication keys. local storage and handling of authentication keys.
Additionally, local specification of OSPF authentication keys and the
associated authentication algorithm is supported for legacy
implementations that do not support key-chains [RFC8177] It is
RECOMMENDED that implementations migrate to key-chains due the
seamless support of key and algorithm rollover, as well as, the
hexadecimal key specification affording more key entropy, and
encryption of keys using the Advanced Encryption Standard (AES) Key
Wrap Padding Algorithm [RFC5649].
Some of the RPC operations in this YANG module may be considered Some of the RPC operations in this YANG module may be considered
sensitive or vulnerable in some network environments. It is thus sensitive or vulnerable in some network environments. It is thus
important to control access to these operations. The OSPF Yang important to control access to these operations. The OSPF YANG
module support the "clear-neighbor" and "clear-database" RPCs. If module supports the "clear-neighbor" and "clear-database" RPCs. If
access too either of these is compromised, they can result in access to either of these is compromised, they can result in

5. Acknowledgements The actual authentication key data (whether locally specified or part
of a key-chain) is sensitive and needs to be kept secret from
unauthorized parties; compromise of the key data would allow an
attacker to forge OSPF traffic that would be accepted as authentic,
potentially compromising the entirety OSPF domain.
