RFC 3871           Operational Security Requirements      September 2004

   High Resolution Time.

      "High resolution time" is defined in this document as "time having

      a resolution greater than one second" (e.g., milliseconds).

   IP.

      Unless otherwise indicated, "IP" refers to IPv4.

   Management.

      This document uses a broad definition of the term "management".

      In this document, "management" refers to any authorized

      interaction with the device intended to change its operational

      state or configuration.  Data/Forwarding plane functions (e.g.,

      the transit of customer traffic) are not considered management.

      Control plane functions such as routing, signaling and link

      management protocols and management plane functions such as remote

      access, configuration and authentication are considered to be

      management.

   Martian.

      Per [RFC1208] "Martian: Humorous term applied to packets that turn

      up unexpectedly on the wrong network because of bogus routing

      entries.  Also used as a name for a packet which has an altogether

      bogus (non registered or ill formed) Internet address."  For the

      purposes of this document Martians are defined as "packets having

      a source address that, by application of the current forwarding

      tables, would not have its return traffic routed back to the

      sender."  "Spoofed packets" are a common source of martians.

      Note that in some cases, the traffic may be asymmetric, and a

      simple forwarding table check might produce false positives.  See

      [RFC3704]

   Out of Band (OoB) management.

      "Out of Band management" is defined as any management done over

      channels and interfaces that are separate from those used for

      user/customer data.  Examples would include a serial console

      interface or a network interface connected to a dedicated

      management network that is not used to carry customer traffic.
