Considering on Implementing a Computer System – Some Thoughts on That

If you are a decision maker that will be making recommendations, advising, consulting or even making the final and actual decision on a new computer or IT system then you need to understand the best process. Today’s IT systems are costly and understanding this process will keep your organization from making mistakes. Thus, I’d like to recommend a very good book to you:

“Computers for Jumping Profits; Understanding, Selecting, Evaluating and Implementing Computer Systems” by David C. Dykstra; 1983.

 

This book tells you how to set up a computer system for any small, medium or large business or any organization or government agency. Although the book is older and the technology has changed over the years, the fundamental principles of planning, budgeting, ratios and accounting remain the same.

 

The author discusses the various folks involved and who their different motivations cause conflict in the implementation phase if a more analytical approach is not taken in the decision making process. For instance the author uses the example of implementing IBM Mainframes and micro-computers and how the advisors and salespeople with different objectives have very different perspectives.

 

This creates a false reality when doing strategic planning and asset allocations, cost analysis and estimates of return on investment through productivity and efficiency. The author also discusses employee training costs, temporary slow down until the users are up to speed and other human factors to be considered.

 

Since this book has to do with IT systems, it also discusses issues with feature creep, challenges with speed, configuration and potential failure. Sometimes IT professionals and definitely their superiors get too caught up in the newest and latest technology and not the reality, functionality or cost.

 

This book is of value to all those decision makers along the way, the information in it is timeless and it hardly matters the time period or the actual technology involved. It is the decision making process that is important and that is why I highly recommend this book.

Book Review: Computer Investigation by Elizabeth Bauchner

Who is the target audience for this book?

Make no mistake. This book is not targeted for computer professionals. If you have a degree in Computer Science or just know a lot about computers, you won’t learn anything from this book. This book is targeted to children in the middle school age group, but it would also be a good introductory book for adults.

That said, what does the book talk about?

What is the science of computer forensics?

Computer forensics is a two-part process. First, data is retrieved and then the data is used. It is different from other forensic sciences because the data usually stands on its own and does not need to be interpreted.

What are the many duties of a computer forensics technician?

While doing their job, computer forensic specialists must preserve evidence, not introduce viruses or worms into a system, handle data properly, keep evidence within the chain of command, reduce the impact of the system’s analysis on any businesses affected, and make sure privileged information is not divulged.

Following those rules, computer forensic professionals find hidden files, swap files, and temp files used by the operating system and by applications. They access these files and protected and encrypted files, searching for information relevant to the case. They analyze the data found, especially in areas normally considered inaccessible. They perform an over all system analysis and list all relevant files. They provide an opinion of the system’s layout and who authored which files. They make notes of attempts to delete or protect files, and they provide expert testimony and/or consultation in court as needed.

The book gives definitions for commonly used words, or jargon, in the industry.

A hacker is someone who is really interested in a piece of technology and learns all possible about the technology.

A cracker is someone who uses their hacker knowledge for bad.

Hackers are white hat, and crackers are black hat hackers.

A phreaker was a person who scammed the telephone company to get free long-distance calls.

Spoofing is mimicking a website (or an email) so the receiver thinks the sender is someone else.

Phishing is trying to get information from people, like their user accounts and passwords, and social security numbers.

A virus is a program, attached to another program, that infects a system when the program is opened. The virus can’t do anything unless the program is opened and ran.

A worm is like a virus, but it can replicate itself without other programs being opened.

A Trojan horse is a program that pretends to be a different kind of program.

Denial of Service (DoS) is when a cracker tries to prevent a system from being accessible by its normal users.
