CYBER CRIMEThe Invisible Criminal is dangerous than Visible one.- AYYAPPAN.P

Cyber crime & computer crime have become a terms that we hear in the news with some

frequency. To protect yourself from cyber crime, you must first understand what it is &how it can work against you. With the increasing popularity of shopping websites, online

banking and other sites that require sensitive personal & financial data, cyber crime hasbecome an ever-present threat.

What is meant by CYBE CRIME ?

Cybercrime encompasses any criminal act dealing withcomputersandnetworks(calledhacking). Additionally, cyber crime also includes traditional

crimes conducted through theInternet. For example: Releasing New films,telemarketing and Internet fraud, identity theft, and credit card account thefts

are considered to be cyber crimes when the illegal activities are committedthrough the use of a computer and the Internet.

Cybercrime also includes non-monetary offenses, such as creating anddistributingviruseson other computers or posting confidential business

information on the Internet.

Perhaps the most prominent form of cybercrime is identity theft, in whichcriminals use the Internet to steal personal information from other users. Two of

the most common ways this is done is throughphishingandpharming. Both of

these methods lure users to fake websites (that appear to be legitimate), wherethey are asked to enter personal information. This includeslogininformation,

such as usernames and passwords, phone numbers, addresses, credit card

numbers, bank account numbers, and other information criminals can use to

"STEAL" another person's identity. For this reason, it is smart to always check

theURLor Web address of a site to make sure it is legitimate before entering

your personal information.

Cyber Laws in INDIA:

The IT Act 2000 attempts to change outdated laws and provides ways to deal with cyber

crimes. We need such laws so that people can perform purchase transactions over the Netthrough credit cards without fear of misuse. The Act offers the much-needed legal

framework so that information is not denied legal effect, validity or enforceability, solely

on the ground that it is in the form of electronic records.

In view of the growth in transactions and communications carried out through electronic

records, the Act seeks to empower government departments to accept filing, creating andretention of official documents in the digital format. The Act has also proposed a legal

framework for the authentication and origin of electronic records / communicationsthrough digital signature.

* From the perspective of e-commerce in India, the IT Act 2000 and its provisions

contain many positive aspects. Firstly, the implications of these provisions for the e-businesses would be that email would now be a valid and legal form of communication in

our country that can be duly produced and approved in a court of law.* Companies shall now be able to carry out electronic commerce using the legal

infrastructure provided by the Act.* Digital signatures have been given legal validity and sanction in the Act.

* The Act throws open the doors for the entry of corporate companies in the business of

appropriate Government.* The IT Act also addresses the important issues of security, which are so critical to the

success of electronic transactions. The Act has given a legal definition to the concept ofsecure digital signatures that would be required to have been passed through a system of

a security procedure, as stipulated by the Government at a later date.

Safety Tips for Cyber Cafe Visitors:

Locations that offer wireless Internet access like hotels and airports typically also providethe use of Internet kiosks or public computers for Web access and word processing. This

is a great benefit for those without their own devices, but can also pose many risks:

1.Key loggers may be installed.Every keystroke you make may be recordedcomprising any login information, even for

VPN connections. Use onscreen keyboard to login. Windows default onscreen keyboardcan be accessed from

Start >> All Programs >> Accessories >> Accessibility >> on-Screen Keyboard

2.Yourbrowsing history may be cached.

People can see what Web sites you've visited, and they may be able to view these cachedsites, which may invade your privacy. Newer browsers have facility for private

browsing(Firefox 3.5, Chrome, Internet Explorer 8 etc.). So when you surf on public PC,use private browsing mode.

3.Saved login information.

Any saved login informationsuch as from clicking the well-known "Remember Me"option when logging into a sitemay allow others to access your account(s).

4.Network Monitoring Tools may be installed.

Someone can view from LAN what are you doing. There are number of remote accesssoftware for business needs that are used for monitoring employees. These may be

installed on LAN from where someone can get real time view from your PC while youare using it.

a firewall. Turn on the firewall that comes with your router as well.

name.

6Keep watch over your children and how they use the Internet. Install parental control

software to limit where they can surf.

SOLUTIONS :

When investigating computer crimes, investigators and forensic accountants often

discover what could have been done to prevent the crimes. The following are some of themost frequently found items. The organizations failed to:

Have written policies and security rules for the use of computers and systems.

Have temporary employees and independent contractors follow the same security

rules as regular employees.

Adjust access as people changed responsibilities internally. Keep up with and close security holes in applications, firewalls, and operating

systems. Maintain virus protection on a fully updated basis.


19/19

Some of the suggestions to improve computer security include implementing the

following: More effective policies for security over proprietary information

Better interaction between the human resources department, the systems

department, and corporate security functions Better internal accounting controls

Better supervision of those with sensitive access to systems Better employee instruction in security issues

Better computer audit software Better software security

Better physical security in the workplace

CONCLUSION:

Never give out your name, address, telephone number, password, school name,parent's name, pictures of yourself, credit cards, or any other personal informationto others online.

If you are the victim of a cyber crime, the first thing you will have to do is to file acomplaint with details of the crime. The subsequent Q & As will familiarize you
