year 1820.
• The first spam email took place in 1978 when it
was sent over the Arpanet.
• The first Virus was installed on an Apple
Computer in 1982.

7. CYBER THREAT EVOLUTION

8. CATEGORIZATION OF CYBER CRIME
• The Computer as a Target
• The computer as a weapon

9. TYPES OF CYBER CRIME
• Hacking
• Denial of service attack
• Virus Dissemination
• Computer Vandalism
• Cyber Terrorism
• Technology Crime

10. HACKING
• Hacking in simple terms means an illegal
intrusion into a computer system and/or
network.

11. DENIAL OF SERVICE ATTACK
• Act by the criminal, who floods the
bandwidth of the victims network.

him of the services.

12. VIRUS DISSEMINATION
• Malicious software that attaches itself to
other software. (virus, worms, Trojan
Horse, web jacking, e-mail bombing etc.)

13. COMPUTER VANDALISM
• Damaging or destroying data rather than
stealing.
• Transmitting virus

14. Types of Cyber Vandalism
Worms- usually spread through e-mails, attaches itself and resends itself
out through your e-mail contacts. Causes files to react slowly, and works its
way through individual and network computers.
Viruses- usually spread through innocent looking links and social network
sites attaching itself to applications, videos, and hyperlinks. Very harmful to
computers, causes hard drive failure, or can contain backdoor Trojan
programs which can contain key-loggers, remote access programs, open
pornography sites on its own, and access to total control over computer.
Computer Hacking – perpetrators break into security systems in order to
use services, change information, or steal information

15. CYBER TERRORISM
• Use of Internet based attacks in terrorist activities.
• Technology savvy terrorists are using 512-bit
encryption, which is impossible to decrypt.

16. Technology Crimes
• Technology used in crime commission other than
computers themselves- includes software

22. Types of Cyber Warfare
Cyber Terrorism- enemies strike at targets without
bombs, such as the American economy, or use
the internet to gather information on future targets
without having to go behind enemy lines.
Cyber Warfare- use of hackers to infiltrate
important systems such as the pentagon, the
National Security Agency, and nuclear weapons
lab.
Can also be used to attack electric power and
essential services

23. TYPES OF CYBER ATTACK BY PERCENTAGE

5P mantra for
online
security
Precaution
Prevention
Protection
Preservation
Perseverance

27. Security
The growing phenomenon of cybercrime is
causing a whole new set of laws and law
enforcement processes.
This causes numerous challenges for law
enforcement, because technology changes
so rapidly it is hard to keep up with the
training

28. CYBER SECURITY
• Internet security is a branch of computer security
specifically related to the Internet.
• It's objective is to establish rules and measure to
use against attacks over the Internet.

30. ADVANTAGES OF CYBER
SECURITY
• Defend us from critical attacks.
• Browse the safe website.
• Internet security process all the incoming and
outgoing data on our computer.

31. CONCLUSION
Technology is destructive only in the hands
of people who do not realize that they are
one and the same process as the universe.
