Email SPAM

What Is Spam

•The word "Spam" as applied to Email means "Unsolicited Bulk Email".

The term "spam" is Internet slang that refers to unsolicited commercial email (UCE) or unsolicited bulk email (UBE). Some people refer to this kind of communication as junk email to equate it with the paper junk mail that comes through the US Mail. Unsolicited email most often contains advertisements for services or products, but very few reputable marketers use UCE to advertise.

•A message is Spam only if it is both Unsolicited and Bulk.

•Unsolicited Commercial Email is normal email
(examples: first contact enquiries, job enquiries, sales enquiries)

•Bulk Email is normal email
(examples: subscriber newsletters, customer communications, discussion lists)

•Technical Definition of Spam

An electronic message is "spam" if

(A) the recipient's personal identity and context are irrelevant because the message is equally applicable to many other potential recipients; AND

(B) the recipient has not verifiably granted deliberate, explicit, and still-revocable permission for it to be sent.

•SPAM Email Criteria

1. Only text without attachments.
2. Text that contains incoherent sentences or disconnected sentences.
3. Definitely messages from addresses not known to the recipient.

Purpose of SPAM

A. These are messages that are designed to test/mar the efficiency of the spam detection systems currently employed by servers.

B. These messages contain coded messages that are flooded across the internet in an attempt to disguise their true origin/destination. The real message could be short one such as "the machine from which this has been sent has serious security holes".

C. This is generated for someone's research project.

D. This is the result of some spam generating software/virus which has bugs.

How the sender gets the email address

•One of the way is the firms that send spam e-mails get the e-mail adresses by opt-in lists. Opt-in email is where the user is given an option to receive "bulk" e-mails. Another way of getting e-mails adresses to send spam e-mails is by dictionary attacks.

•Another way is by Dictionary attack is an e-mail spamming technique in which spammer sends out thousands or millions of e-mails with randomly generated addresses using combinations of letters added to known domain names by hoping it might reach a percentage of actual e-mail addresses. Beside that, dishonest subscribe or unsubscribe newsletter services is the way of getting email addresses to send spammers by selling your email address for a commission. For example, when users click on the "unsubscribe" link that provided in newsletter, they are actually confirming that a real person exists at their email address.

•Another way spammers discovers email addreses is search common sources for email addresses. The pages that are spammer are usually visit are web forums, chat rooms and web-based interfaces to use net because lots of email addresses can be found there. To avoid being detected, spammers seek to send their emails from a distributed network of computers. These computers are not even their own but those of unsuspecting users. Besides, the spammers should disguise their email address when use it on the net or use disposal use disposable email addresses.

•To prevent spam e-mails there is a computer software designed which is also known as spam blocker. The other names for the software are spam filters, anti-spam and spam fighters. This software works by blocking unsolicited e-mails sent in bulk to many recipients from entering the mail inbox of user.

A Study of Challenger of Jordan Public Health Care Government: A case study in implementing Hakeem

This Symposium on IT Governance, Management & Audit (SIGMA) 2012 was held in College of Information Technology, Universiti Tenaga Nasional on 20^th June 2012 at 2.30 pm. The theme of SIGMA is “Governing the Future. Take Charge”. The venue assigned to us is BW-G-R15. There were several papers presented such as Investigation of ISG Section in Mosul Health in Iraq and A Study of Challenger of Jordan Public Health Care Government. We choose A Study of Challenger of Jordan Public Health Care Government: A case study in implementing Hakeem. This paper was presented by Duo’ A Nassar.

Hakeem is Arabic word which means doctor in English. The benefits of EHR are patient safety and satisfactions are ensured, quality service is provided and the cost is controlled. Idea of Hakeem came from King Jordan and was continued by his son, King Abdullah bin Hussin. The health sector is divided into three phases. The first phase starts in 2009 until 2011. This phase is about EMR which contains one public hospital and Amman comprehensive center. Second phase which starts in 2011 until now has two public hospitals and one comprehensive center. Phase three is about future plan. It deploys and connects the EHR in all Jordan public hospitals.

Several challenges were identified to make EHR a success. The challenges are divided into two which are global challenges and special challenges. For global challenges, there are financial, technology and publicity and legacy challenges. Meanwhile for special challenges, it involves two challenges which are stakeholder and organization challenges. The challenges governor are governmental leadership, Jordanian strategic initiative, work policy, resell ideas, data warehouse and data mining techniques, support and few others.

In conclusion, this assignment has been helpful to us in getting knowledge about symposium and on how a research is being presented. Besides that, we were able to know the technology from different countries such as Jordan and Amman. This assignment also has been helpful for all of us to gain experience in preparing ourselves for next assignment which is the academic paper.
