Title: Implementing Policy in the Enterprise Network

Implementing Policy in the Enterprise Network
  • Lewis

Introduction
  • Policy in network management
  • In the early 70s
  • Monitoring and controlling the access rights of
    multiple users and resources in large distributed
    systems
  • Now
  • Configuration, accounting, fault, and performance
    management
  • A general policy framework is needed for
    controlling the behavior of the agents the
    enterprise network comprises, including network
    users, administrators, troubleshooters,
    applications running on the network, and
    operational parameters of the network hardware.

The Motivation for Policy Management
  • Policies are akin to rules that govern actions.
  • Household rules
  • Kids have to be in bed by 8 p.m.
  • Dogs are not allowed on couches or beds
  • A person (or a group of persons) exercises
    control of the household
  • makes up the rules,
  • monitors the domain to which the rules apply,
  • and takes appropriate actions when the rules are
    broken.

  • Small business organizations typically have no
    need for policies.
  • However, if the operation becomes increasingly
    complex, there develops a need to effect policies
    that govern the behavior of the employees.
  • With the advent of cooperative/distributed work
    among human and software agents, the concept of
    policy naturally extends to the government of
    human/computer and computer/computer interaction.

The dimensions of policy
  • The outside band approximates high-level
    policies.
  • The inner band suggests lower-level policies (the
    actual behavior of the network).
