31. Evolution The concept of Internet
was originated in 1969 and has
undergone several technological
& Infrastructural changes as
discussed below:
The origin of Internet devised
from the concept of Advanced
Research Project Agency Network
(ARPANET).
ARPANET was developed by
United States Department of
Defense.

32. Basic purpose of ARPANET was
to provide communication
among the various bodies of
government.
Initially, there were only four
nodes, formally called Hosts.
In 1972, the ARPANET spread
over the globe with 23 nodes
located at different countries
and thus became known as
Internet.

71.  SET is an open encryption and security
specification designed to protect credit
card transactions on the Internet. The
current version, SETv1, emerged from a
call for security standards by MasterCard
and Visa in February 1996. A wide range of
companies were involved in developing the
initial specification, including IBM,
Microsoft, Netscape, RSA, Terisa, and
Verisign. Beginning in 1996.

72. SET provides three services:
• Provides a secure
communications channel among
all parties involved in a
transaction
• Provides trust by the use of
X.509v3 digital certificates
• Ensures privacy because the
information is only available to
parties in a transaction when and
where necessary.

73. The SET specification lists
the following business
requirements for secure
payment processing with
credit cards over the
Internet and other
networks:

74. Provide confidentiality of
payment and ordering
information
Ensure the integrity of all
transmitted data
Provide authentication that
a cardholder is a legitimate
user of a credit card
account

75. Provide authentication that a
merchant can accept credit card
transactions through its
relationship with a financial
institution
Create a protocol that neither
depends on transport security
mechanisms nor prevents their
use
Facilitate and encourage
interoperability among software
and network Providers

76. Confidentiality of
information
Integrity of data
Cardholder account
authentication
Merchant authentication

77.  A digital signature is a mathematical
technique used to validate the
authenticity and integrity of a message,
software or digital document. It's the
digital equivalent of a handwritten
signature or stamped seal, but it offers
far more inherent security. A digital
signature is intended to solve the
problem of tampering and
impersonation in digital
communications.

78. Digital signatures can
provide evidence of
origin, identity and status
of electronic documents,
transactions or digital
messages. Signers can
also use them to
acknowledge informed
consent.

83. ENCRIPTION:
Encryption or Data
encryption is a common
and effective security
method—a sound choice
for protecting an
organization’s
information.

84. Authentication
Privacy
Regulatory
Compliance
Security

85. Symmetric
Encryption Method
Asymmetric
Encryption Method
Hashing

86. The ability to allow only authorized users,
programs or processes system or resource access
– The granting or denying, according to a
particular security model, of certain permissions
to access a resource – An entire set of
procedures performed by hardware, software
and administrators, to monitor access, identify
users requesting access, record access attempts,
and grant or deny access based on pre-
established rules. – Access control is the heart of
security.

87. – Social Networks
– Web Browsers
 – Operating
Systems
– Firewalls

88. Firewall is a barrier
between Local Area
Network (LAN) and the
Internet.
It allows keeping private
resources confidential and
minimizes the security
risks.

89. It controls network
traffic, in both
directions.
Both hardware and
the software can be
used at this point to
filter network traffic

90. There are two types of
Firewall system: One
works by using filters at
the network layer and
 The other works by
using proxy servers at
the user, application, or
network layer.

91. Firewall management must be
addressed by both system
managers and the network
managers.
The amount of filtering a
firewall varies. For the same
firewall, the amount of
filtering may be different in
different directions
