23.  To prevent cyber stalking avoid disclosing any
information pertaining to oneself. This is as good as
disclosing your identity to strangers in public place.
 Always avoid sending any photograph online
particularly to strangers and chat friends as there
have been incidents of misuse of the photographs.
 Always use latest and up date anti virus software to
guard against virus attacks.
 Always keep back up volumes so that one may not
suffer data loss in case of virus contamination
 Never send your credit card number to any site that is
not secured, to guard against frauds.

24.  Always keep a watch on the sites that your
children are accessing to prevent any kind of
harassment or depravation in children.
 Web site owners should watch traffic and check
any irregularity on the site. Putting host-based
intrusion detection devices on servers may do
this
 Web servers running public sites must be
physically separate protected from internal
corporate network.

25.  History is the witness that no legislation has
succeeded in totally eliminating crime from the globe.
 The only possible step is to make people aware of
their rights and duties (to report crime as a collective
duty towards the society) and further making the
application of the laws more stringent to check crime.
 Undoubtedly the IT Act is a historical step in the cyber
world. Further I all together do not deny that there is a
need to bring changes in the Information Technology
Act to make it more effective to combat cyber crime.
