CYBER SECURITY Subject : New Developments in I.T. Prepared by – Vardhil Gandhi Roll # 4 A2 Batch

CONVENTIONAL CRIME-:

Security is necessary for prevention of crime. And hence, we first need to know what crime is ! So first, we will learn about the word crime and what does the term cyber crime refer to in detail. Crime is a social and economic phenomenon and is as old as the human society. Crime is a legal concept and has the sanction of the law. Crime or an offence is “ a legal wrong that can be followed by criminal proceedings which may result into punishment.” The hallmark of criminality is that, it is breach of the criminal law. Per Lord Atkin “ the criminal quality of an act cannot be discovered by reference to any standard but one: is the act prohibited with penal consequences”. CONVENTIONAL CRIME- Vardhil Gandhi - Cyber Security - New Developments in IT

CYBER CRIME:

Cyber crime is the latest and perhaps the most complicated problem in the cyber world. “Cyber crime may be said to be those species, of which, genus is the conventional crime, and where either the computer is an object or subject of the conduct constituting crime” “ Any criminal activity that uses a computer either as an instrumentality, target or a means for perpetuating further crimes comes within the ambit of cyber crime ” A generalized definition of cyber crime may be “ unlawful acts wherein the computer is either a tool or target or both ” CYBER CRIME Vardhil Gandhi - Cyber Security - New Developments in IT

We can categorize Cyber crimes in two ways::

We can categorize Cyber crimes in two ways: T he Computer as a Target :-using a computer to attack other computers. e.g. Hacking, Virus/Worm attacks, DOS attack etc. The computer as a weapon :-using a computer to commit real world crimes. e.g. Cyber Terrorism, IPR violations, Credit card frauds, EFT frauds, Pornography etc. Vardhil Gandhi - Cyber Security - New Developments in IT

Technical Aspects:

Technical Aspects Technological advancements have created new possibilities for criminal activity, in particular the criminal misuse of information technologies in the following ways: a. Unauthorized access & Hacking b. Trojan Attack c. Virus and Worm attack d. E-mail & IRC related crimes 1. Email spoofing 2. Email Spamming 3. Email bombing e. Denial of Service attacks We will now discuss about them in detail. Vardhil Gandhi - Cyber Security - New Developments in IT

a. Unauthorized access & Hacking:- :

a. Unauthorized access & Hacking:- Access means gaining entry into, instructing or communicating with the logical, arithmetical, or memory function resources of a computer, computer system or computer network. Unauthorized access would therefore mean any kind of access without the permission of either the rightful owner or the person in charge of a computer, computer system or computer network. Every act committed towards breaking into a computer and/or network is hacking. Hackers write or use ready-made computer programs to attack the target computer. They possess the desire to destruct and they get the kick out of such destruction. Some hackers hack for personal monetary gains, such as to stealing the credit card information, transferring money from various bank accounts to their own account followed by withdrawal of money. By hacking web server taking control on another persons website called as web hijacking Vardhil Gandhi - Cyber Security - New Developments in IT

b. Trojan Attack:- :

b. Trojan Attack:- The program that acts like something useful but does things that are quiet damping. The programs of this kind are called as Trojans. The name Trojan Horse is popular. Trojans come in two parts, a Client part and a Server part. When the victim (unknowingly) runs the server on its machine, the attacker will then use the Client to connect to the Server and start using the trojan . TCP/IP protocol is the usual protocol type used for communications, but some functions of the trojans use the UDP protocol as well. Vardhil Gandhi - Cyber Security - New Developments in IT

c. Virus and Worm attack:- :

c. Virus and Worm attack:- A program that has capability to infect other programs and make copies of itself and spread into other programs is called virus. Programs that multiply like viruses but spread from computer to computer are called as worms. Vardhil Gandhi - Cyber Security - New Developments in IT

d. E-mail & IRC related crimes:- :

d. E-mail & IRC related crimes:- 1. Email spoofing Email spoofing refers to email that appears to have been originated from one source when it was actually sent from another source. 2. Email Spamming Email "spamming" refers to sending email to thousands and thousands of users - similar to a chain letter. 3. Sending malicious codes through email E-mails are used to send viruses, Trojans etc through emails as an attachment or by sending a link of website which on visiting downloads malicious code. Vardhil Gandhi - Cyber Security - New Developments in IT

d. E-mail & IRC related crimes:- :

4. Email bombing E-mail "bombing" is characterized by abusers repeatedly sending an identical email message to a particular address. 5. Sending threatening emails 6. Defamatory emails 7. Email frauds 8. IRC related Three main ways to attack IRC are: “verbal” attacks, clone attacks, and flood attacks. Vardhil Gandhi - Cyber Security - New Developments in IT d. E-mail & IRC related crimes:-

e. Denial of Service attacks:- :

e. Denial of Service attacks:- Flooding a computer resource with more requests than it can handle. This causes the resource to crash thereby denying access of service to authorized users. Vardhil Gandhi - Cyber Security - New Developments in IT
