Parkerian Hexad

The Parkerian hexad is a set of six elements of information security proposed by Donn B. Parker, renowned security consultant and writer. The term was coined by M. E. Kabay. The Parkerian hexad adds three additional attributes to the three classic security attributes of the CIA triad (confidentiality, integrity, availability).

The Parkerian Hexad attributes are the following:

  • Confidentiality
  • Possession or Control
  • Integrity
  • Authenticity
  • Availability
  • Utility

These attributes of information are atomic in that they are not broken down into further constituents; they are non-overlapping in that they refer to unique aspects of information. Any information security breach can be described as affecting one or more of these fundamental attributes of information.

I think I don’t require to provide the explanation of C-I-A here. Let’s look at the other attributes.

Jul 31

Posted by Vinod Puthuseeri in Information Security, Information Security Management System, Information Security Risk Assessment, Information Security Risk Management, Physical Security, Risk Assessment | No Comments

In the recent news Infosys becomes the first private company to get CISF security. I have also been reading in yet another blog about a organization conducting mocks drills for terrorist’s attacks. It is quite interesting to see that organizations are now taking security as a prime concern. As mentioned in my previous blog about frisking of VIP’s at airports, the exception mentioned there is an age old rule that was implemented when terrorism was a not major concern.

Security Breach – Who's responsible?

Jan 27

The very first lesson taught to me in my computer classes where “A computer is as smart as you are” and this statement holds good even today. For the computer would do only that a person would want it to do. The only advantage a computer has over human is that of speed and storage capacity.

While looking at various aspects of data loss, the end reason always point to “PEOPLE”. The above statement holds good not only because there are data loss (which is now the high rated security risks), even if you look at any frauds that has happened in the recent past, everything has been manipulated by “HUMAN”. No matters what standards are adopted, what stringent rules are set in an organization, frauds still happen.

ISMS Implementation – The bottom-Up approach

Oct 23

Posted by Vinod Puthuseeri in ISO 27001:2005, Information Security | 1 Comment

All the while we have been hearing and believing that ISMS implementation in any organization requires management approval without which it would be a failure. True!!!

For any project in an organization for that matter, management approvals are a must cause for a project to kick-start and complete with desired results, requires resources, budget, tools etc. These can be achieved only if the project manager shows the management that there is value created by doing this project which could favor the organization. The value could be of many ways which ultimately boils down to making profits or avoiding monetary/image loss.

Vulnerability Management Program

Oct 10

Posted by Praveen Reddy in Information Security | 2 Comments

Introduction

It is quite obvious that, every organization want to serve its clients with out any interruptions. If not handled properly, sometimes, presence of a small vulnerability in a system or in the network may lead to interruption of the services offerings to clients. This may result in losing the trust of clients or loss of revenue.

Vulnerability assessment is a simple process of identifying and reporting vulnerabilities.

It provides a way to detect and resolve security problems before someone or something can exploit them. By conducting periodic vulnerability assessments, management could validate the security measures they have deployed.
