• Individuals or groups are using the anonymity cyberspace to threaten citizens, specific groups communities and even the countries.

WHAT IS CYBERTERRORISM??• It is Internet based

attacks in terrorist activities

• It includes acts of large-scale disruption of computer networks

• Majorly personal computers attached to the Internet, by the means of tools such as computer viruses.

EXAMPLES OF CYBERTERRORISM

Hacking into computer systems.

Introducing viruses to vulnerable networks.

Website Defacing. Denial-of-

Service(DOS) attacks.

Terroristic threats made via e-mail.

3 MOST COMMON ATTACK METHODS

• IP spoofing• Password

Cracking • Denial-of-

service attacks

IP SPOOFING

Creation of IP packets with forged source IP with the purpose of concealing the identity of sender

Used in Denial-of-Service attacks

Effective in corporate networks where users can log in without a username or password

PASSWORD CRACKING• It usually referred to

repeated attempts to identify a user account or password and is called brute-force attacks

• It is implemented using brute-force attacks, Trojan horse programs and IP spoofing.

• Example is weak encryption used by Microsoft windows XP, can easily be attacked.

DENIAL OF SERVICE ATTACKS• It focus on making a

service unavailable to intended users

• 2 forms of DoS attacks: a)crash services

b)flood services• One common attack

method involves saturating the target machine with communications requests such that it cannot respond to the traffic

EXAMPLE OF CYBERTERRORISM ATTACKS

• 9/11 attack.• Ahmedabad bomb
