Software Copyright Theft

Denition:

"Downloading, copying orborrowing software (for free)without the permission of theowner "


3/67

Overview o sotware copyright

thet: Sotware is oten developed at massive costs (both

nancially and in terms o time! by companies and

individ"als#

$eca"se sotware is digital% it is very easy to either

download illegally rom the internet or to ma&e copies

o it witho"t the permission o the owner# (i#e# copying

a C' or downloading rom pirate bay!# This is oten

called Sotware )iracy*

+aws e,ist to help prevent the developers o sotware

rom having their wor& downloaded or copied by others

or ree#


4/67

-hat do these laws cover.

Sotware sho"ld not be copied% sold or givenaway to other people

Sotware sho"ld not be "sed on a networ& omore "sers than yo" have paid or (e#g# /0 "sersinstead o 10!

2enting o"t sotware witho"t permission is illegal

Stealing code rom sotware and then "sing it inyo"r own sotware prod"ct is illegal

Using the name o copyright sotware on yo"rprod"ct is illegal ()assing of yo"r prod"ct as3icrosot -ord or e,ample!


5/67

Software iracyre!ention

Sotware can be protected againstpiracy in a n"mber o ways incl"ding:

1# Serial 4"mbers/# 5olograms6# +icence agreements


6/67

Serial 4"mbers

-hen sotware is being installed%"sers are oten as&ed to enter a"ni7"e n"mber which proves the

sotware is original#

Serial n"mbers are s"pplied with the

original copy o the sotware#


7/67

5olograms

5olograms are oten "sed on thepac&aging o sotware and theyindicate that the copy is gen"ine#

Sotware witho"t a hologram on thepac&aging is "s"ally an illegal copy#


8/67

+icence 8greements

+icence agreements are part o thesotware installation process and theyinorm the "ser e,actly how they arelegally allowed to "se the prod"ct#

Users are re7"ired to agree to termso "se beore they can complete theinstallation#

Computer iruses

Denition:

"# self$copying program that hasbeen created with the purpose ofdamaging a computer system


10/67

Overview o comp"ter vir"ses:

The rst comp"ter vir"s sent over the Internet was created in19 by 2obert 3orris#

Comp"ter vir"ses can ca"se h"ge problems i they are allowedto inect a comp"ter#

;ir"ses are programs that a"tomatically ma&e replicates(copies! o themselves and then attach to other les within thecomp"ter#

8ny les which have vir"ses attached to them are said to havebeen inected#


11/67

-hat problems can vir"sesca"se.

;ir"ses can be designed to carry o"tdiferent malicio"s (harm"l! "nctions#Some incl"de:

8nnoying pop

5ow do vir"ses inectcomp"ters.

There are many ways that vir"sescan inect a comp"ter# The mostcommon incl"de:

'ownloading inected les rom theinternet

Email attachments that contain

inected les

)l"gging a =ash memory stic& thatcontaining inected les into yo"r

comp"ter

re!enting Software irus%nfections

4ew comp"ter vir"ses are beingcreated all the time and this meansthat yo" sho"ld ta&e steps to red"ce

the chance that yo" comp"ter anddata become inected# The bestmethods are o"tlined in the table

&ac'ing

Denition:

"The process of accessing acomputer system withoutpermission"


17/67

Overview o hac&ing:

5ac&ing is where people brea& intocomp"ter systems witho"tpermission# These people are &nownas hac&ers#

5ac&ers oten "se the Internet tobrea& into the system#


18/67

-hy do people try to hac& into comp"ter systems.

5ac&ers try to brea& into comp"ters or theollowing reasons:

To ca"se damage to les and data by deleting orchanging them

To commit ra"d by stealing data (ban& n"mbersetc!

To access sensitive inormation

Simply to see i they are clever eno"gh to beat thesystems sec"rity#


19/67

re!enting &ac'ing and&ac'ers

There are vario"s methods yo" can"se to help stop hac&ers romaccessing yo"r comp"ter les and

data# These incl"de:

*irewall+s

-ser$%D+s and .obust asswords

/ Data 0ncryption


20/67

@irewalls

@irewalls provide a shield betweenyo"r comp"ter and the Internet#

@irewalls can bloc& "nwanted data(incl"ding hac&ers! rom reachingyo"r comp"ter# They can also stop

yo"r comp"ter rom connecting to"nwanted websites#

These Aobs have been created d"e to the need or big computer networ'swithin companies# 4etwor& managers ma&e s"re that comp"ters on thenetwor& run smoothlyand are secure#

1eb Design

The Internet has seen a h"ge demand or both commercial (business) and

personal web sites-eb designers create these sites and &eep them "p todate#

/ Systems #nalyst

)rogrammers create all the software that can be used on a computer# Thisis a h"ge ind"stry and prod"ces things li&e operatingsystems% applications(word% e,cel etc! and computer games#

6Computer 0ngineers

Engineers are needed to build the high$tech computersthat we "se today#

icroprocessor ControlledDe!ices

1hat is a microprocessor2

8 microprocessor is really A"st a tinycpu built onto a single chip #

3icroprocessors are p"tinto electronic de!icesto control

how they function#

0=ects of microprocessors in thehome

8ny electronic device in yo"r ho"sethat needs to be controlled in someway is li&ely to contain a

microprocessor# E,amples o theseare listed below:


28/67

Computer System

o"r des&top )C or laptop will containa microprocessor calleda C-(power"l machines will

contain more than one!#

The C)U controls all the

processingthat gos on within thecomp"ter#

%ntelligent ?!ens ; icrowa!es ;*ridges

The microprocessor inside intelligent ovens can readthe barcodes on pac'aging and thena"tomatically set the temperatureand coo'ingtimeto the perect levels#

Intelligent microwaves wor& in m"ch the same way#

Intelligent ridges can read the barcodes on ood anddetermine the +use by+dates# @ood that is d"e to good

bad is then automatically mo!ed to the front ofthe fridge so that yo" "se it rst#
