Q.4. Discuss about the ethical challenges of IT.

Or Discuss the important aspects of the security, ethical and societal dimensions of the use of IT in the business. (2013-14) 

Ans. Ethical Challenges of IT: It has major impacts on society and so it raises ethical issues in the areas of crime, privacy, employment, health and working conditions. The important aspects of security and ethics in business are as under:

1. Cyber Crime or Computer Crime: It is a growing threat to society that is caused by the criminal or irresponsible actions of individuals who are making maximum use of computers and the Internet. It is a criminal activity where a computer is the source or tool for crime. Computer crime includes unauthorised use or access of hardware, software, data or network resources, unauthorised copying of software, unauthorised release of information or using computer or network resources illegally.

2. Privacy: It is the wish to remain unnoticed or unidentified in the public domain. It is the degree to which private information exposed depends on how the public will receive this information. Privacy may be invaded by:

(a) unreasonable intrusion upon person’s privacy. 

(b) public disclosure of private facts. 

(c) characterising a person publicly.

Unauthorised use or mistakes in the computer matching of personal data is a controversial threa to privacy.

3. Employment Challenges: The impact of IT on employment is a major ethical concern is related to the use of computers. It can influence employment by affecting the total number o altering the skill mix of jobs through changes in occupational demand and altering the skill mix of through changes in the skill content of occupations without changing occupational distribution.

4. Challenges in Working Conditions: IT has eliminated various critical tasks in the office waste on factory that were earlier performed by people. In other instances, this allows people to conce more challenging and the interesting assignments, upgrades skill level of the work to be perform creates challenging jobs that require highly developed skills in computer industry.

5. Challenges to Individuality: Computer-based systems are criticised as impersonationships which depersonalise the activities which are computerised as they eliminate human present in non-computer systems. Many e-business systems h depersonalisation and regimentation. The widespread use of na proved the development of people-oriented and personalised information systems.

6. Health Issues: The uses of IT led to the emergence of vario causing health problems like job stress, damaged arms and neck muscles, eye strain and even death by can be used to solve human and social problems through societal solutions, such as medical diagnosis, computer assisted inastruction, enforcemental quality and control and law enforcement.

Occupational safety and health is a cross disciplinary area that is concerned with protecting thfe safety, health and welfare of people engaged in work or employment. It aims at the promotion an maintenance of highest degree of social well-being of workers in all occupations and their protection from risks which result from factors affecting health. In this regardd, there is a study called Ergonomics which refers to scientific discrpline developed for concentrating on factors governing health and safety laws and guidelines.

Q.5. What are the different security tools? 

Ans. Security Tools: Different security tools are used to check the of these tools are:

1. Firewalls: It is a software or hardware that allows only those external

users which have specific characteristics to access a protected network. It works by establishing a barrier between network and the external Internet. It is an approach to implementing a security policy which defines the services which are to be permitted to various users. A firewall implements an access policy by forcing connections to pass through them.

2. Virtual Private Networks (VPNs): It is a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some of the larger networks. A VEN 15 a private network that uses a public network to connect the remote sites together. It uses virtual connections routed through the Internet from company’s private network to a remote site.

3. Encryption: It is an important way to protect data and other computer network resources especially on the Internet, Intranet and also Extranet. It involves using mathematical algorithms to transform digital data into a scrambled code before they are transmitted and to decode the data when they are received. The method which is mostly used makes use of a pair of public and private keys that are unique to every individual.

4. Authentication: It is the process by which the identity of an entity is established. The entity is declared authentic when presented credentials are valid and sufficient. Authentication does not determine which entities should be given access but only verifies that an entity is the claimed one. The rights to resources can be assessed only when the entity is authenticated.

5 Intrusion Detection System: It is a software or a hardware designed in order to detect unwanted attempts for accessing, manipulating or disabling the computer systems mainly through a network. These attempts can be in the form of attacks and IDs cannot detect them directly. This system assess system and file integrity and analyse system configurations and vulnerabilities.

6. Antivirus: These are the program codes which introduce malicious logic into the computer stems. These softwares are specifically written to defend a system against the threats that malware Microsoft strongly recommends these softwares as they defend the computer systems against types of malwares and not only the viruses. So, antivirus protection is needed to get defense against these malicious softwares.

7. E.mail Monitoring: E-mail is the most exploitable point of entry to insert destructive data into omnuter systems by the hackers. E-mail attachments are also a potential source of viruses. The onular mail servers support antivirus functionality which is to be updated time-to-time.

8. Denial of Service Defenses: These cause direct or indirect harm to the organisation’s systems. fed a server with unlimited requests so that it doesn’t have the resources to service any other valid requests. The server tries and respond to every request but is unable to deliver the response because it is unreachable. Thus, one infected system could infect other systems leading to a wide sdcale of infected systems. So, precautions must be taken at the victims ISP or at the victim’s website.

Q.6. Write a note on 1. Cyber Laws, 2. IT Act 2000

Ans. 1. Cyber Laws: In simple way, we can say that cyber crime is unlawful act wherein the computer is either a tool or a target or both. Cyber crimes can involve criminal activities that are traditional in nature, such as theft, fraud, forgery, defamation and mischief, all of which are subject to the Indian Penal code. The abuse of computers has also given birth to a gamut of new age dcrimes that are addressed by the information Technology Act, 2000

We can categorise cyber crimes in two ways:

1. The Computer as a Target: Using a computer to attack other computers, w.g. Hacking, Virus/ Worm attacks, DOS attack, etc.

2. The Computer as a Weapon: Using a computer to commit real world crimes. Po Cyber Terrorism, IPR violations, Credit card frauds, EFT frauds, Pornography, etc are crimes regulated by cyber laws or internet laws. 

MBA Notes For Technical Aspects

Technological advancements have created new possibilities for criminal activity, in particular the criminal misuse of information technologies such as:

1. Unauthorised 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. Unauthorised 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

2. Trojan Attack: The program that act like something useful but do the 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.

3. 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 du spread from computer to computer are called as worms.

4. E-mail & IRC Related Crimes: Some E-mail and IRC related crimes are: 

(a) E-mail Spoofing: E-mail spoofing refers to e-mail that appears to nail that appears to have been originale one source when it was actually sent from another source.

(b) E-mail Spamming: E-mail spamming refers to sending an email to thousands of users to a chain letter. 

(c) Sending Malicious Codes Through E-mail: E-mails are used to send viruses, through emails as an attachment or by sending a link of website which code.

(d) E-mail Bombing: E-mail bombing is characterised by abusers repeatedly sending an e-mail message to a particular address.

(e) Sending threatening e-mails. 

(f) Defamatory e-mails. 

(g) E-mail frauds. 

(h) IRC related.

5. Denial of Service Attacks: Flooding a computer resource with more requests tha This causes the resource to crash thereby denying access of service attempts to ‘Flood’ a network, thereby preventing legitimate

service to authorised users. Exa

ate network traffic, attempt

S than it can handle s. Examples include tempts to disrupt

connections between two machines, thereby preventing access to articular individual from accessing a service, attempts a particula person,

6. Distributed DoS: A distributed denial of service (DoS) a Internet to break into computers and using them to attack a network. Hundreds or thousands of system or website.

Types of DoS: There are three basic types of attacks: 

1. Consumption of scarce, limited or non-renew time. Even power, cool air or water can affect.

2. Destruction or alteration of configuration information

3. Physical destruction or alteration of network components
