Information Security - What is it?

Computer security may seem to throw unnecessary roadblocks into your daily routines in RSU #20.  However, the importance of security can not be over emphasized and you are an key piece in the security of Information Technology (IT) systems throughout our RSU.  This information security blog/news is designed to raise your awareness of the vital importance of data security in general, and IT security specifically.

First, I would like to recommend a basic, easy-to-read booklet on computer security.  It is titled, "Computer Security, 20 Things Every Employee Should Know, " ISBN# 0-07-226282-6, and published by McGaw-Hill Professional Education.  The cost is about $8.00.  This booklet contains basic security information and is written for the non-geek.  It is not full of technical jargon and drives home the importance of maintaining computer security.

There are three fundamental principles in effective security whether one is dealing with IT security or security in general:  Confidentiality, Integrity, and Availability.  In the IT security field, we refer to this as the C-I-A triad.  

Confidentiality:  This implies a trust or a feeling of assurance.  In security, this is ensuring data is not disclosed to unauthorized persons.
Integrity:  From the dictionary, "a rigid adherence to a standard of values."  In security, data integrity is the reliability that information received is in an identical state to when it was last accessed by an authorized person.

Availability:  Accessibility to data by authorized users.

This triad forms the building blocks for IT and information security.  Your role in information security is vital.  Security is a chain- only as good as the weakest link.  When working with data (digital, verbal, or written), we, as employees, present a vulnerability to that data.  To have an effective security program, we all must be aware of our responsibilities.  Let the journey begin.
