What do we think ?

10. In general, social networks are self-organizing, emergent, and complex,
such that a globally coherent pattern appears from the local interaction of
the elements that make up the system. These patterns become more
apparent as network size increases
Analysis of social networks

11. Although levels of analysis are not necessarily mutually exclusive,
there are three general levels into which networks may fall: micro-
level, meso-level, and macro-level.

Levels Of Analysis

12. At the micro-level, social network research typically begins with an
individual, snowballing as social relationships are traced, or may
begin with a small group of individuals in a particular social context.
In this level analysis is done at somewhat personal level.
Micro level
In the micro level analysis relationship between two people
communication and for what purpose ; their communication is
analyzed.

13. In general, meso-level theories begin with a population size that falls
between the micro- and macro-levels. However, meso-level may
also refer to analyses that are specifically designed to reveal
connections between micro- and macro-levels
Meso level
The analysis is performed between groups and their relationship. Above
diagram shows how different groups are interconnected.

14. Rather than tracing interpersonal interactions, macro-level analyses
generally trace the outcomes of interactions, such as economic or
other resource transfer interactions over a large population.
Macro level
The analysis is of overall network. Above figure shows . A section of
large scale social network

15. Attackers may use social networking services to spread malicious
code, compromise users’ computers, or access personal information
about a user’s identity, location, contact information and personal or
professional relationships.
Social networking & Crime

16. • Limit the information you put in the social networking sites.
• Don’t put personal information like your family details, addresses,
personal photographs, video, etc. In case if you put your personal
photographs try to change settings and make visible only for friends
• Be careful if you want to meet social networking friends in
personal, sometimes it may not be their true identity which is
posted on the social networking sites.
Safe Social Networking

17. • Always clean browser’s cookies and cache .
• Don’t ever share your password with anyone; and keep changing your
password regularly. Always use proper password (min 8 digits with a
mix of alpha numeric & special characters)
• Use Virtual Keyboard, wherever possible to enter your password for
better security as these cannot be captured by key-loggers.
Safe Social Networking

18. Social Networking sites are becoming very popular especially among the
growing kids. These sites expose the kids to various risks like online
bullying, disclosure of personal information, cyber-stalking, access to
inappropriate content, online grooming, child abuse, etc. In addition
there are many more risks like fake profiles with false information,
malicious application, spam, and fake links which leads to phishing
attacks etc.
Challenges to social networking

19. Though the social networking is beneficial, the problem that arises is
of information overload and security. Social networks, unlike the
common media, do not have a pattern as to how much information
has to be conveyed and where to draw the line.
Too much of information may confuse users. Security might be another
area of concern where people can get illegal access to a user’s
information. The future of social networking looks very promising but
still it has to deal with the problems associated with it.
