Did some housekeeping on our ICT blog at the beginning of the class. Then Mr.Z gave us a assignment to do which is a short presentation on 4 different topics which are phishing, virus (Trojan Horse and Salami Attack), hacking and security measure (biometrics and authentication). My presentation will be on security measures.

Session 10

We met with a Japanese teacher, Mrs Nobuko through Skype. Only four students had a chance to talk to her and I was one of them. The first student was Kieron, who had only joined us for a couple of weeks. The second student was Mahsuri and the third student was Jeevan. The last student was me. We talk a bit of Japanese cultures and the Malaysian cultures. It was a pleasant experience. Mr.Z said that we will be doing this again in the future with other teacher from all around the world.

Session 09

Mr.Z started our lesson with controversial contents which are information that causes disagreement in opinions and may cause the disruption of peace. Examples of controversial contents are pornography and slander. Pornography are any form of media or material that depicts erotic behavior and cause sexual excitement. Pedophiles are people who are sexually aroused by naked pictures of innocent children. Where as slandering is a legal term of false and malicious statements about someone.
   The impact of pornography are: i) criminal acts ii) sexual addictions or perversion iii) develop low moral
values iv) erode good religious, cultural and social belief and behavior.
   As for the impact on slandering: i) develop into a society that disregards the truth and honesty ii) bad habits of spreading facts that are unreal iii) leads to unnecessary arguments iv) cause people to have negative attitudes toward another person
There are several cyber laws like Digital Signature Act 1997, Computer Crimes Act 1997, Telemedicine Act 1997, Communication and Multimedia Act 1998.

Session 08

Started session 08 with a video about password. In the video we mustn't share password with anyone and if someone knows about it, we must change it. Our password must at least be 8 characters and contains upper and lower cases as well as numbers. We mustn't use the same password on every site and NEVER use dictionary words. Last but not least change the password as often as possible.
After that, we continue our lesson with Computer Security. It means protecting our computer system and the information inside it. Hackers, crackers and script kiddie can hack into our computer system and take the information they want. There are 3 types of security: a) hardware security b) software/data security c) network security. Then we learned about threats that can be made to a computer. Malicious codes like virus, Trojan horse, logic bomb, trapdoor and backdoor, worm and others. Other than malicious codes, natural and environmental surroundings can also cause threat to the computer. For example, flood, tornado, excessive heat and more.
Lastly we learned about security measures that can be taken to protect the computer system. By using data backup which copies the entire data and puts it into another system, cryptography which is a process of hiding information or anti-virus which protects the computer against viruses. Not only that, anti-spyware and firewall can also be use to protect the computer system. Anti-spyware is a program placed in a computer without the user's knowledge and firewall is a device or set of devices designed to permit or deny network transmissions based upon a set of rules and is frequently used to protect networks from unauthorized access while permitting legitimate communications to pass.

Session 07

Right before we enter class, Mr.Z checked our lesson outcomes 01 and after that, he told us there will be replacement class on Sunday, 12/2/2012 at 10 a.m. Then we started our lesson with the meaning of computer ethics and cyber laws.

Ethics -> a moral philosophy where a person makes a specific moral choice and sticks to it and computer Law -> a legal system comprising of rules. Under this ethics and law, we must respect the ownership, privacy and property. Other than that, IP or Intellectual Property are works created by inventors, authors and artist.

We also learn another topic which is privacy. In privacy, there is data -> collection of raw unprocessed facts, figures and symbols. There is also information -> processed data.
There are ways to threaten computers. For example: by using cookies, electronic profile or spyware.
Authentication is a process where users verify that they are who they say they are. For example: biometric is by identifying users through fingerprint, facial, hand, iris, retinal, voice, signature or the callback system which are commonly used in banks.
