The document discusses various aspects of computer privacy and security. It outlines ways to protect privacy such as using passwords and encryption. Password protection allows only authorized users to access a computer, while public/private key encryption scrambles messages during transmission. The document also discusses how email privacy can be compromised if packets are intercepted during routing over the internet. It then covers information security strategies like restricting access and using biometrics. Malicious programs, or malware, are designed to damage systems, and examples provided are viruses, worms, and Trojan horses. The document concludes with a discussion of ethics issues involving copyright, digital rights management, and plagiarism.

3. Computer Privacy
 Everyone takes privacy in normal life for granted,

4. Ways of computer privacy
 Password
 Encryption
 Email Privacy

5. Password
 Not just to protect the computer but to make sure that
the computer issues by authorized worker or user only.
 Password is private combination of characters
associated with the user name that allows access to
computer resources

6. Encryption
 With public key encryption there are two keys, one
public and the other private.
 The public key needs to be known.
 To send a message to a friend, you uses his public key
to encrypt the message.
 Your friend then uses his private key to decode the
message after receiving it.

7. Email Privacy
 When u send a message by email, the message is
broken into packets and the packets are sent out over
the Internet.
 The number of packets depends on the size of
message.
 Each message has the internet address of the recipient.
 This means there may be some places between the
packets could be intercepted and examined

8. Information Security
 The quality or state of being secure to be free from
danger
 Security is achieved using several strategies
 Security is achieved using several strategies
simultaneously or used in combination with one
another
 Security is recognized as essential to protect vital
processes and the systems that provide those processes
 Security is not something you buy, it is something you
do

9. Information can be
 Created
 Stored
 Destroyed
 Processed
 Transmitted
 Used – (For proper & improper purposes)
 Corrupted
 Lost
 Stolen

10.  HACKER: Create or improve programs and shared
those program with fellow hackers . Typically are not
criminal.
 CRACKERS: Share programs designed to gain
unauthorized access computer systems or disrupt
networks. Typically are criminals.
 CARDERS: Specialize in stealing, trading and using
stolen credit cards over the internet.

11. MALICIOUS PROGRAMS (MALWARE)
Design to damage or disrupt computer system. Most
common types of malware
 viruses
 worms
 Trojan horses.

12. Measure to Protect Computer
Security
RESTRICTING ACCESS:
 Sometimes security matter of putting guards on
company computer rooms and checking the
identification of everyone admitted. Other times it use
 Biometric scanning such as fingerprint and iris.
 Password are secret words or phrases that must be
keyed into a computer system to gain access.

13. Ethics
 Standards of moral products.
 The right to keep personal information, such as credit
ratings and medical histories, from getting into
unauthorized hands.

14. Two important issues in computer
ethics
 Copyright and Digital Right Management

16. Software Piracy
 Digital Millennium Copyright Act

illegal to download copyright-protected music and videos
from Internet.
 Digital rights management (DRM)
collection of technologies designed to prevent copyright
