Information architecture - identifies where and how important information, such as customer records, is maintained and secured.
Backup and Recovery
Backup - An exact copy of a system's information.
Recovery - The ability to get a system up and running including the data in the event of a system crash or failure.
Fault tolerance - A computer system designed that in the event a component fails a backup component or can immediately take over with no loss of service.
Business Continuity Planning (BCP)
Is a plan for how an organisation will recover and restore partially or completely interrupted critical function(s) within a predetermined time after a disaster or extended disruption.
Web Service - Contains a repertoire of Web-based data and procedural resources that use shared protocols and standards permitting different applications to share data and services.
The two primary parts of web services are:
Event - Detect threats and opportunities and alert those who can act on the information.
Service - More like software products than they are coding projects.
Open Source - Refers to any program whose source code is made available for use or modification as users or other developers see fit.
ARCHITECTURE TRENDS
These reflect how an organisation today must continually watch new architecture trends to ensure they can keep up with new and disruptive technologies.
Three architecture trends that are quickly becoming requirements for all businesses includeing:
Service orientated architecture, visualization, grid computing.
Service Orientaed Architecture (SOA) - is a business drive IT architectural approach that supports integrating a business as linked, repeatable tasks or services.
Service
SOA can be a business task, such as checking a potential customer's credit rating only when opening a new account. Services are "like" software products.
eXtensible Markup Language (XML) - A markup language for documents containing structured information.
Loose Coupling
This is the capability of services to be joined together on demand to create composite services, or disassembled just as easily into their functional components.
Loose coupling is way of ensuring that the technical details are decoupled from the service.
Virtualisation is a framework dividing the resources of a computer into multiple execution environments. It is a way of increasing physical resources to maximize the investment in hardware.
Virtualisation reduces hardware infrastructure and increases the utilization of software. Consolidates (and often reduces) power and cooling requirements.
Additional benefits - Rapid application deployment, dynamic load balancing, streamlined disaster recovery.
Grid computing is an aggregation of geographically dispersed computing, storage, and network resources, coordinated to deliver improved performance, higher quality service.The benefits to a business include, allowing widely dispersed departments and businesses to create virtual organisations. Providing instantaneous access to massive computing and data resources.

CP1005 - Lecture Four - Ethics and Information Systems
Ethics - the principles and standards that guide our behaviour toward other people.
Ethical issues affected by technology advances
– Intellectual property
– Copyright
– Fair use doctrine
– Pirated software
– Counterfeit software'
Privacy is a major issue and right to privacy is the law.
Privacy: The right to be left alone when you want to be, to have control over your own personal possessions, and not to be observed without your consent.
Confidentiality: The assurance that messages and information are available only to those who are authorized to view them.
Information has no Ethics - Acting ethicially and legally are not always the same.
Ethical Computer Use Policy
Ethical computer us policy: Contains general principles to guide computer user behaviour.
Information Privacy Policy - The unethical use of information typically occurs "unintentionally" when it is used for new purposes.
AUP - Acceptable Use Policy - A user must agree to before provided access to a network or the internet.
Email Privacy Policies, Internet Use Policy (Describes Available Internet Services, Purpose and Restriction of Internet Access, Complements ethical computer use policy, describes user responsibilities, states user responsibilities, states ramification for violations)
Anti-Spam Policy - Unsolicited email.
Ethics in the Workplace
Workplace monitoring is a concern for many employees. Organizations can be held financially responsible for their employees' actions.
Monitoring Technologies
The tracking of people's actions by such measures as number of keystrokes, error rate, and number of transactions processed.
INFORMATION SECURITY
Information Security is the protection of information from accidental or intentional misuse by persons inside or outside an organization. Protecting intellectual assets costs money; about 15% of the IT budget in Asian Pacific Companies.
There are Five Steps to Creating an INFORMATION SECURITY PLAN
There are three primary information technology security areas:
1. Authentication and authorisation.
2. Prevention and resistance.
3. Detection and response.
Something the User Knows, Such as a User ID and Password. FACT over 50% of help-desk calls are password related.
Types of Hackers
White-hat Hackers, Black-hat Hackers, Hactivist, Script kiddies or script bunnies, Cracker, Cyber terrorist.
Detecting and Responding
By far the most effective form of protection is virus protection and firewall protection.
Virus Software written with malicious intent to cause annoyance or damage may include; Worm, Denial-of-service attack, Trojan-horse virus, backdoor program or polymorphic virus and worm.

- Develop the information security policies.
- Communicate the information security policies.
- Identify critical information assets and risks.
- Test and reevaluate risks.
- Obtain stakeholder support.

Disruptive Technology
Distruptive technology is a way of doing something that dones not initially meet the needs of existing customers.
Digital Darwinism implies that organizations which cannot adapt to the new demands placed on them for surviving in the information age are doomed to extinction.
Sustaining Technology produces an imporved product that customers are eager to buy.
Sustaining technologies tend to provide use with a better, faster and cheaper product in an established market.
The Internet - Business Disruption
One of the biggest forces changing business is the internet. Organisations need to be able to transform as markets and technologies change.
Focusing on the unexpected allows an organization to capitalize on the opportunity for new business.

Evolution of the Web
Fundamentals about the internet - Remember the internet was developed first by the US department of deference to communicate back and fourth from each base with information to their scientists.
Gradually the internet moved from a military and scientific pipeline into a communication tool for everyone. (Internet / Protocol)
WWW a global hypertext system that uses the Internet as it's transport system. Important acronyms and terms include HTTP, URL, HTML and Client/Server.
The internet's impact on information as allowed easy compilation of information on subjects, increased richness, increased reach and improved content.
The internet has made it easy and possible to perform business in ways not previously possible.
It has also brought about the Ethical issue of (Digital-Divide) which is when those with access to technology have great advantages over those without access to technology.
Web 2.0 is a set of economic, social and technology trends that collectively allow people to interact with the web rather than only being able to read a static page. (Blogging, Wikis, Syndication, Napster, Bittorent, Flickr)
API - Application Programming Interface is a set of routines, protocols and tools for building software applications.
Mashup Editor - WSYIWYGs (What you See is What You Get) for mashups.
A website where people with common interests engage; MySpace, Facebook, Linkedin.
E-Business Basics
e-Commerce - The process of buying and selling goods and services over the internet.

C2C - e-Auction, Forward Auction, Reverse Auction.
Organisational Strategies for e-Business include; Marketing / Sales, Financial Services, Procurement, Customer Service and Intermediearies.
Generating Revenue - Banner Ads, Blogs, RSS, Podcasting, SEO and Spamdexing.
Measuring your success can be done through Cookies, Click throughs, Banner Ads, bounce rate. Website metrics can be provided through Web Analyics (tracking) the exact pattern of a consumer's navigation through your website.
Mobile Commerce is the ability to purchase goods and services through a wireless internet - enabled device.
