Blog Entry 7.1 - IS Security (Part A)

If the Ferrum Times is threatened by floods, power outages, or other unexpected issues we will back up our files using cloud computing, have a generator on hand, and have keyboards and screens lock after not being in use for 5min. If the Ferrum Times is threatened by employees or consultants stealing or putting viruses on the server for revenge to deal with these issues we will give a password to every employee that way we can keep an eye on which employee does what and also install anti-virus software on all our computers. If the Ferrum Times manages to get a virus on our computers that could delete all our stories for the day and past records we will install a firewall and anti-virus software. When the Ferrum Times sends messages about how much paper we are going to buy we will encrypt the data using public key technology. If we are attacked by hackers then they could steal information and also look at our clients private records in order to protect ourselves and clients we will use photo ID cards to make sure that they are employees and also install a proxy server which will be able to identify if the person is an employee by their password.

5.1 Critique Your Competitor’s E-Commerce Website

Web Site: washingtonpost.com

Rule 1: The Website should offer something unique   Rating: 4.5

I gave washingtonpost.com this rating because it offers more than news it also offers move listing, comics, and clips from sport games. According to alexa.com washingtonpost.com is ranked 325 globally.

Rule 2: The Website should be aesthetically pleasing   Rating: 4.5

I gave washingtonpost.com this rating because it has a lot of movement and people could get distracted and just find another news oriented site to check the news. Also a lot of the articles are bunched together making it hard to click on the one the person wants.

Rule 3: The Website must be easy to use and fast    Rating: 5

I gave washingtonpost.com this rating because if a user uses the tabs at the top of the page or types in a subject they will be able to find articles on that subject.

Rule 4: The Website must motivate people to visit   Rating: 4

I gave washingtonpost.com this rating because even though it has news that might interest some people the way the web site is presented it was not motivating people to stay on the site.

Rule 5: You must advertise your presence on the web  Rating: 4.5

This web site advertises sports and other businesses. I would have given it a 5 if they advertised the newspaper a little bit more.

Rule 6: You should learn from your website      Rating: 5

The user learns about the different events that are happening around the world. According to alexa.com this web site is ranked 325 globally and 72 in the US.
