Introduction

Technology by itself cannot solve all network security problems.

Cyber terrorism, according to the definition of the FBI:

Premeditated, politically motivated attack against information, computer systems, computer programs, and data that results in violence against noncombatant targets by subnational groups or clandestine agents.

Typically, loss of life in a cyber attack would be less than in a bombing attack.

Introduction (cont.)

Virus software won’t prevent a user from manually opening an attachment and releasing a virus.
A technologically secured network is still vulnerable if former employees (perhaps some unhappy with the company) still have working passwords. Or if passwords are simply put on Post-it notes on computer monitors.
A server is not secure if it is in a room that nearly everyone in the company has access to.
Your network is not secure if end users are vulnerable to social engineering.

All these could lead to significant deaths: train wrecks, hospital deaths, loss of air traffic control resulting in plane crashes, and so forth.

What Is a Policy?

A security policy is a document that defines how an organization deals with some aspect of security. There can be policies regarding end-user behavior, IT response to incidents, or policies for specific issues and incidents.

All these could lead to significant deaths: train wrecks, hospital deaths, loss of air traffic control resulting in plane crashes, and so forth.Using the guidelines provided in this week’s chapter (and other resources as needed), create a step-by-step IT security policy for handling user accounts/rights for a student who is leaving prematurely (drops, is expelled, and so on).

You will need to consider specialized student scenarios, such as a student who works as an assistant to a faculty member or as a lab assistant in a computer lab and may have access to resources most students do not.
