think, pair, share
This week, our task is to do some basic internet research regarding our topic in week 2 which in my case is about :Internet and Computer Security (Virus, Spam, Phishing). As usual, me and Al Arimi are in the same group again. Before we start doing the task my exploring to http://www.ukm.my/library/ and http://www.ezplib.ukm.my/login, we are given the password and login ID from our class representative. therefore we are able to surf the e-library without much trouble. the links in our task sheets are very useful because i've never tried UKM e -library before. the UKM e-library is full of informative journals and research which in my opinion is very useful in my course as lots of our tasks require us to do academic reading.
me and my group mate did some exploring to the UKM e-library and search some e-journal which are related to our task for this week which is aboutInternet and Computer Security (Virus, Spam, Phishing) and what should be done in Malaysia to solve the problem arises from internet security and virus.
after that, we write a report regarding our reading using open office 3.3. this is not the first time i am using open office because i've learnt to use it before when i am still studying in Matriculation program. even so, i will like to express thousand of gratitude to my group mate Al Arimi for downloading the open office 3.3 for my group. therefore i just need to install it and use it straight away.
in our report, we are writing a report with caution for not to plagiarize the e-journal notes that we collected. thereforem we cite it in the correct way thought by the link

week 3:Management System (CMS / LMS)
week 2b(reflection)
CMS/LMS
there are a lot of information for both CMS and LMS in the internet. therefore we are able to collect informations from various types of sources. before i receive this task, i never heard about what is CMS/LMS. this task has help me to understand the differences between CMS/LMS and normal websites in terms of both's weaknesses and strengths. As i did some further reading regarding this topic, i found out that the CMS/LMS is very similar to blog which we can edit the post and the layout whenever we want without much effort.
Google Docs
Its my first time for me and my group mate for creating a google doc for the report for this task. we are glad that we are able to learn a lot from this course.
We are sorry
I am sorry because me and my group mate are able to finish this task after the due date.

Question 4:Internet and Computer Security (Virus, Spam, Phishing)
Definition:
virus :A computer virus is a computer program that can copy itself and infect a computer. The term "virus" is also commonly but erroneously used to refer to other types of malware, including but not limited to adware and spyware programs that do not have the reproductive ability. A true virus can spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive.
spam:Spam is the use of electronic messaging systems (including most broadcast media, digital delivery systems) to send unsolicited bulk messages indiscriminately. While the most widely recognized form of spam is e-mail spam, the term is applied to similar abuses in other media
phishing: the activity of tricking people by getting them to give their identity, bank account numbers, etc. over the Internet or by email, and then using these to steal money from them

DIFFERENT TYPES OF COMPUTER VIRUSES
WAYS TO PREVENT COMPUTER VIRUSES ATTACK
1. Install a reliable anti virus program
2. Install anti-spyware and anti-malware programs.
3. Avoid suspicious
4. Never Open Email Attachments Without Scanning Them First
5. Set up Automatic Scans
6. Watch Your Downloads
7.Update your computer program
8. Know What To Look For
9. Stay Away From Cracked Software.
10. Install a Firewall
Spam
how spamming occurs?
Spammers collect email addresses from chat rooms, websites, customer lists, newsgroups, and viruses which harvest users' address books, and are sold to other spammers. They also use a practice known as "email appending" or "e-pending" in which they use known information about their target (such as a postal address) to search for the target's email address. Much of spam is sent to invalid email addresses.
The cost of spam is far less than postal bulk mailings. An advertiser could spam 10,000 recipients for under $100 versus several thousand dollars for a postal mailing.
effect of spamming:
Receiving spam is actually more like receiving a junk fax or a sales call on a cellular phone because the cost of distributing the advertisement is borne by the recipient (or the recipient's Internet service provider (ISP)), not the sender. (The annual cost of spam to U.S. corporations is currently $9 to $10 billion a year.)
Every ISP pays for the right to operate on the Internet by purchasing bandwidth, the "space" it uses to transmit over the Internet. As the volume of spam directed through an ISP increases, the bandwidth becomes crowded, often slowing down the user's Internet access. To counter this, the ISP must pay for filtering software (which can also slow access) or pay to increase the amount of bandwidth. In both cases the expense is often passed along to subscribers. To get an idea of how much bandwidth is consumed by spam, America Online estimated that one-third of the 30 million daily email messages it transfers is spam.
how to prevent spam:
Overview of Phishing Scams
Phishing scams are just another attempt to get valuable information. Scammers send a mass email to every address they can find. Typically the message will appear to come from a bank or financial institution. The email states that you should update your information for one reason or another, and they usually provide a link that you can click to do so.
This all sounds reasonable and it may look legitimate, but phishing scams are anything but legitimate. The link provided does not take you to the financial institution’s website. Instead, you’ll be submitting your information to a website run by the scammers.
Why People Fall for Phishing Scams
Anybody can be tricked by a sophisticated phishing scam. Simple phishing scams are easy to spot, but the best scammers are actually pretty smart. They use a variety of tricks to make the phishing scam look like a legitimate process. For example, they might include a graphic from the bank right on the email message or website. Or, the link provided in the email may look like it goes to the bank’s website while the victim is actually sent to a very
Advice for Victims of Phishing Scams
If you have been snagged by phishing scams in the past, you need to be vigilant. First, let your financial institution know what happened. They will likely want to pursue the scammer, and they will monitor your account more closely. Next, I always suggest that victims of phishing scams put a fraud alert on their credit report by contacting one of the major credit agencies. Finally, you’ll need to keep a close eye on your mail and your accounts. If statements stop showing up or if you see unusual activity, call your bank immediately.
The Process of Phishing
Planning. Phishers decide which business to target and determine how to get e-mail addresses for the customers of that business. They often use the same mass-mailing and address collection techniques as spammers.
Setup. Once they know which business to spoof and who their victims are, phishers create methods for delivering the message and collecting the data. Most often, this involves e-mail addresses and a Web page.
Attack. This is the step people are most familiar with -- the phisher sends a phony message that appears to be from a reputable source.
Collection. Phishers record the information victims enter into Web pages or popup windows.
Identity Theft and Fraud. The phishers use the information they've gathered to make illegal purchases or otherwise commit fraud. As many as a fourth of the victims never fully recover
How to prevent phishing.
* Never enter personal information in a pop-up screen.
* Do not click on links in a pop-up screen.
* Do not copy web addresses into your browser from pop-ups.
* Legitimate enterprises should never ask you to submit personal information in pop-up screens, so don’t do it.
7. Protect your computer with a firewall, spam filters, anti-virus and anti-spyware software
8. Check your online accounts and bank statements regularly

- Don’t forward an email from someone you don’t know to a list of people.
- Before you join a list, make sure the list owner or Web master will not sell your address.
- Preview your messages before you open them.
- Use a complicated email username.
- Use a spam filter.
- Make sure your privacy settings are set so you don't receive marketing from other sites in your AOL and Yahoo profiles.

2. find a partner who is doing the same topic.(Al Arimi)
3. do an online discussion with my partner(Al Arimi) via Facebook group (doc)
4. share the link.
What had i learn today?
due to the topic that i chosen, i have to browse the internet in order to search information about Internet and Computer Security (Virus, Spam, Phishing). i learnt the definition for the word virus, spam and phishing before i start searching for any related materials and information. the word "Phishing" is a totally new words for me, therefore it is crucial for me to understand the meaning before i do the searching in the internet.
to do a discussion with my partner who is Al Arimi, I created a doc file in my Facebook Group. we cooperate with each other to compile the notes and information that we get from the internet. we will edit the doc from time to time whenever we got new information from the internet.
in our topic, we discussed about internet security as well as the problem that happens to the world which includes virus, spamming, and phishing. Before i start the information searching, i do not really understand what is a computer virus and how they work to attack one's file or computer. now i finally understand how spamming, virus and phishing occur and i will certainly be more careful when i check my email and i will never clicks on those unknown links from those unknown sender because of the risk of scam, spam, virus, and phishing.

First Week Class.
In our 1st interaction with our subject lecturer(Tg Norazlan Tg Sulaiman ) of the subject GGGE1155. Computer in Education on 5th July, we are briefed with the task that we should do throughout the week after some introduction of the course.
1.register a yahoo and google account
We are required to open a official email account for both google and yahoo. we are also being advised to use a proper and meaningful name for our email account. These accounts will be used for educational purposes in our courses.
2. register a facebook account using the newly created google account.
We register a new facebook account as soon as we finished applying the new email address. I followed the instructions that are noted in our course proforma. but the process of opening a new account for facebook is not as easy as it seems because our IPG's wifi has block Facebook. therefore we are having a hard time to create a facebook account.
3. joining a yahoo group and creating our own yahoo group
we are given the url of the group that we should join which is http://groups.yahoo.com/group/ge1155ipg/ and we also created our own group in the yahoo group using our own name as the group name. the group will act as a web portfolio which functions as our learning portfolio for this subject in this semester which is awesome to be as this will be my first web portfolio.
4. blog registration
this blog is very meaningful for me as this is my first blog in my life. i can't believed that i will have a blog of my own. nevertheless, this is a one in a million chance to learn to use a blog and keep on track on the digital websites. we are required to write our reflection of what we've learnt in the class.
reflection:
this subject, computer in education is a very important subject for me as I am good in computer software and programs. this is a good chance for me to learn all these and hopefully it will help my in my career someday. registering all those accounts takes time as our IPG blocked certain websites and the internet speed is very slow. it certainly tested my patience. it is frustrating when the internet connection keeps on disconnecting while i'm applying a new account for google and yahoo. hopefully the situation will change soon. overall, i've learn quite a lot in this first week class alone. i hope i can learn more things in the following week!!
