Slide 1: CYBERTERORISM CYBERTERRORISM
Distributed attacks to against information creating alarm and panic. It is linked with information warfare that is the collection of valuable information and spreading it to demoralize the person from whom the information is obtained. Hacks that are able to reach valuable information make controversy in the society. It affects people and a countries economy by using the information to get into someone bank account and transfer the money to its own account. Physiologically it can traumatize the person who is being extortionate as personal information can be exposed to other people by transactions or e-mails. As cyber terrorism takes place when the hacker is able to break down into the system and access to the valuable information, a password is needed to be use or also biometrics, that is the recognition of physical characteristics. The harder the password the harder for the hacker to break down. To prevent anyone from hacking it easily biometrics is a good way to enter into someones database or even do the password with different characters.
Solutions are use different case, and mix symbols with number and letters, and change it monthly to be harder to obtained or guessed. Another solution for this might be biometrics, as they it is not able to replicate a characteristic of anther human either than by cloning e.g. “Myth busters” showed that they photocopied someone else’s finger print and it worked. However this happens rarely and not everyone has the capacity to do something so perfect to infringe through the system, it is a way to protects the computer system or files under this security system. Example of weak password : apple Example of normal password : (apple)* Example of strong password: (Apple)*82
COMPUTER SECURITY
FOR BEGGINERS
SPYWARE
Is designed to infiltrate in computer with the purpose of
PASSWORD
Characters used for authentication to gain access to a resource. Use specifically to protect the computer system. The easier a password is to remember the faster it has the probability of being hacked. Hacking is breaking down into the computer system and having control of it. It can either be obtained by extortion forcing the individual l to give the password involuntary, or extracting cryptography ( the study of hiding things) by forcing a party to behave involuntary, or even brute force, by cracking the password even though it takes a long period of time, specially if it has different type of characters, like not only letter if not numbers also included.
contaminating it as a “virus”. It is able to collect information stored in the computer and copy it to send it to the original creator. Information such as your name, you address, you phone number you passwords for any account online that you might have used, this gives out personal information that might be used to harm the person or enter their account such as their bank account if they had the users PIN and gain access to the individuals money. It also installs you additional software and uses memory making the computer speed slower. Usually the spyware are not easily detected by the users It suggests that it can secretly monitor computer, but it can also gather information from the computer monitoring and send it to a third party. It is known to be able to change compute settings, or accessibility, the speed of the connections. To avoid this malicious software companies have created “ anti-spyware”, and are used specially by users running “ Microsoft’s windows”. This enables spywares to infiltrate in your computer protecting your information and prevent it from being stolen. LINK TO DOWNLOAD ANTI- SPYWRE http://www.scanwith.com/AntiSpyware.htm

STEP UP TO THE CHALLENGE
Slide 2: BIOMETRICS
Is the method of recognizing a person by its physical and behavioral traits. For example in physical we include the shape of body, as the DNA, the retina, the Finger prints or hand palm geometry, the odor or scent of the person. And behavioral by the typing, rhythm, gait, voice ( can also used in physical as everyone has its own vocal track) Biometrics operate in two methods Verification of one to one comparison with a stored template of the information provided, and identification with one to many comparison to identify a “pair” with a already existing template in the database. Even thought it is a solution for password hacking when using only symbols or number or letter, the risk for this can be that you rely upon features that can be damaged and no longer acquired. For example if you loose your finger, you will no longer have the ability to introduce your finger print, if you have a through operation or when you grow the voice changes and may not allow the original user to be identified nor verified. However there are also other risks; we have false negative that does not identify the individual when it is the original user, and false positive, when it incorrectly matches the input pattern and accepts it. Solutions to this problem might be to have more than one verification of the behavioral of physical characteristics ; for example to cheek your voice and eye, not only one, having more security for personal information. Cloning might be another problem as they can clone one of you feature as you fingerprint , photocopy it and be able to introduce the system.
VIRUS
ADWARE
Adware is a software that is used for advertisement mainly. Other people in someone’s computer and sometimes without their consentient can install it in the computer. It automatically displays advertisement weather the user know about it or not. E.g. Eudora, plays advertisements with the purpose of being demonstrated with a demo of something for free so that users observes weather if he likes what he is observing or not; for free. This is an advantage for people looking to buy something, however not everyone wants to and sometimes as this has the capability to see what web pages people are browsing (mainly used in businesses), and this is not comfortable for most people as is a lack of their privacy. (Peer to peer file-sharing program). It sends advertising by spying on what you have preciously observed and send you something related. This can interrupt you while surfing the net and also invades your privacy and send information from your computer to the header. This information may be used in bad ways as they can gain access to accounts such as banks and steal money. It is also capable of downloading and installing spyware making your computer slower and reducing its memory. This can be prevented by using Ad-Aware, by detecting any intruccion of adware and may remove it.
It is a computer program that can make a copy of himself. True Virus can only spread from a computer to others the data and information that identifies the source and the destination of material, known as payloads. It can be transferred thought the internet or network Web over HTTP and FTP or through a removable medium such as a floppy disk , USB, CD act. It can infect other computers by sending infected files due to the virus and replicate and continue this pathway. Installing an antivirus in the computer can prevent this. this programs scans all incoming data & block any threats that are trying to infiltrate. Files are can and if a malware is found it are then removed. However this can sometimes degrade computers performance if not designed correctly. “ virus removal tool” can also be useful to remove virus, for example the McAfee Stinger and the Microsoft Windows Malicious Software Removal Tool, which are sometimes more effective than antivirus.
