<div class="MsoNormal" style="line-height: normal; text-align: justify;">
<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt;">Non-repudiation
is the ability to prove that an operation or event has taken place, so that
this cannot be repudiated later. For e-mails, for example, non-repudiation is
used to guarantee that the recipient cannot deny receiving the message, and
that the sender cannot deny sending it. Non-repudiation (NR) is one of the
security services (or dimensions as defined in the document X.805 by the ITU)
for point to point communications. Secure communications need to integrate a
service in charge of generating digital evidence (rather than simply
information logs) in order to resolve disputes arisen in case of network errors
or entities' misbehaviour when digital information is exchanged between both
points.</span></div>

<b style="mso-bidi-font-weight: normal;"><span style="font-family: "Times New Roman","serif"; font-size: 14.0pt;">Q3. what is privacy and security on the internet ?</span></b></div>
<b>Data Security</b><br />
<div style="text-align: justify;">
Data security is commonly referred to as the
confidentiality, availability, and integrity of data. In other words, it is all
of the practices and processes that are in place to ensure data isn't being
used or accessed by unauthorized individuals or parties. Data security ensures
that the data is accurate and reliable and is available when those with
authorized access need it. <a href="http://business.ftc.gov/privacy-and-security/data-security"><span style="color: windowtext; text-decoration: none; text-underline: none;">A data
security plan</span></a> includes facets such as collecting only the
required information, keeping it safe, and destroying any information that is
no longer needed. These steps will help any business meet the legal obligations
of possessing sensitive data. </div>
<b style="mso-bidi-font-weight: normal;"> <span style="mso-bidi-font-weight: bold;">Data Privacy</span></b><br />
<div style="text-align: justify;">
Data privacy is suitably defined as the
appropriate use of data. When companies and merchants use data or information
that is provided or entrusted to them, the data should be used according to the
agreed purposes. The Federal Trade Commission enforces penalties against <a href="http://www.ftc.gov/opa/2006/01/choicepoint.shtm"><span style="color: windowtext; text-decoration: none; text-underline: none;">companies that have negated to ensure
the privacy of a customer's data</span></a>. In some cases, companies have
sold, disclosed, or rented volumes of the consumer information that was
entrusted to them to other parties without getting prior approval. </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<b style="mso-bidi-font-weight: normal;"><span style="font-size: 14.0pt;">Q4. What is DMZ why it is used .</span></b></div>
<div style="text-align: justify;">
In computer networks, a DMZ (demilitarized zone)
is a computer host or small network inserted as a "neutral zone"
between a company's private network and the outside public network. It prevents
outside users from getting direct access to a server that has company data.
(The term comes from the geographic buffer zone that was set up between North
Korea and South Korea following the UN "police action" in the early
1950s.) A DMZ is an optional and more secure approach to a firewall and
effectively acts as a proxy server as well.</div>

<b style="mso-bidi-font-weight: normal;"><span style="font-size: 14.0pt;">Q5. For what application RSA is recommended ?</span></b></div>
<div style="text-align: justify;">
The RSA algorithm is used worldwide to secure
Internet, banking and credit card transactions. </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<b style="mso-bidi-font-weight: normal;"><span style="font-size: 14.0pt;">Q6. What is the use of digital signature standard ?</span></b></div>
<div style="text-align: justify;">
Digital Signature Standard (DSS) is the <a href="http://searchsecurity.techtarget.com/definition/digital-signature"><span style="color: windowtext; text-decoration: none; text-underline: none;">digital signature</span></a>
<a href="http://whatis.techtarget.com/definition/algorithm"><span style="color: windowtext; text-decoration: none; text-underline: none;">algorithm</span></a> (DSA)
developed by the U.S. National Security Agency (<a href="http://searchsecurity.techtarget.com/definition/National-Security-Agency"><span style="color: windowtext; text-decoration: none; text-underline: none;">NSA</span></a>)
to generate a digital signature for the <a href="http://searchsecurity.techtarget.com/definition/authentication"><span style="color: windowtext; text-decoration: none; text-underline: none;">authentication</span></a> of
electronic documents. DSA is a pair of large numbers that are computed
according to the specified algorithm within parameters that enable the authentication
of the signatory, and as a consequence, the <a href="http://searchdatacenter.techtarget.com/definition/integrity"><span style="color: windowtext; text-decoration: none; text-underline: none;">integrity</span></a> of
the data attached. Digital signatures are generated through DSA, as well as
verified. Signatures are generated in conjunction with the use of a <a href="http://searchsecurity.techtarget.com/definition/private-key"><span style="color: windowtext; text-decoration: none; text-underline: none;">private key</span></a>;
verification takes place in reference to a corresponding <a href="http://searchsecurity.techtarget.com/definition/public-key"><span style="color: windowtext; text-decoration: none; text-underline: none;">public key</span></a>.
Each signatory has their own paired public (assumed to be known to the general
public) and private (known only to the user) keys. Because a signature can only
be generated by an authorized person using their private key, the corresponding
public key can be used by anyone to verify the signature.</div>

A <span style="mso-bidi-font-weight: bold;">virtual private network</span> (<span style="mso-bidi-font-weight: bold;">VPN</span>) extends a <a href="http://en.wikipedia.org/wiki/Private_network" title="Private network"><span style="color: windowtext; text-decoration: none; text-underline: none;">private
network</span></a> across a <a href="http://en.wikipedia.org/wiki/Public" title="Public"><span style="color: windowtext; text-decoration: none; text-underline: none;">public</span></a> network, such as the <a href="http://en.wikipedia.org/wiki/Internet" title="Internet"><span style="color: windowtext; text-decoration: none; text-underline: none;">Internet</span></a>.
It enables a computer or network-enabled device to send and receive data across
shared or public networks as if it were directly connected to the private
network, while benefiting from the functionality, security and management
policies of the public network. A VPN is created by establishing a virtual <a href="http://en.wikipedia.org/wiki/Point-to-point_%28network_topology%29" title="Point-to-point (network topology)"><span style="color: windowtext; text-decoration: none; text-underline: none;">point-to-point</span></a> connection
through the use of dedicated connections, virtual <a href="http://en.wikipedia.org/wiki/Tunneling_protocols" title="Tunneling protocols"><span style="color: windowtext; text-decoration: none; text-underline: none;">tunneling protocols</span></a>, or traffic encryption.
Major implementations of VPNs include <a href="http://en.wikipedia.org/wiki/OpenVPN" title="OpenVPN"><span style="color: windowtext; text-decoration: none; text-underline: none;">OpenVPN</span></a>
and <a href="http://en.wikipedia.org/wiki/IPsec" title="IPsec"><span style="color: windowtext; text-decoration: none; text-underline: none;">IPsec</span></a>.<br />

which applies the <a href="http://en.wikipedia.org/wiki/Data_Encryption_Standard" title="Data Encryption Standard"><span style="color: windowtext; text-decoration: none; text-underline: none;">Data Encryption Standard</span></a> (DES) cipher
algorithm three times to each data block.</div>
<div style="text-align: justify;">
The original DES cipher's <a href="http://en.wikipedia.org/wiki/Key_size" title="Key size"><span style="color: windowtext; text-decoration: none; text-underline: none;">key size</span></a>
of 56 bits was generally sufficient when that algorithm was designed, but the
availability of increasing computational power made <a href="http://en.wikipedia.org/wiki/Brute-force_attack" title="Brute-force attack"><span style="color: windowtext; text-decoration: none; text-underline: none;">brute-force attacks</span></a> feasible. Triple DES provides
a relatively simple method of increasing the key size of DES to protect against
such attacks, without the need to design a completely new block cipher
algorithm.</div>

<b style="mso-bidi-font-weight: normal;"><span style="font-size: 14.0pt;">Q12 What is massage authentication code ?</span></b></div>
In <a href="http://en.wikipedia.org/wiki/Cryptography" title="Cryptography"><span style="color: windowtext; text-decoration: none; text-underline: none;">cryptography</span></a>,
a <span style="mso-bidi-font-weight: bold;">message authentication code</span>
(often <span style="mso-bidi-font-weight: bold;">MAC</span>) is a short piece of
information used to <a href="http://en.wikipedia.org/wiki/Authentication" title="Authentication"><span style="color: windowtext; text-decoration: none; text-underline: none;">authenticate</span></a> a <a href="http://en.wikipedia.org/wiki/Message" title="Message"><span style="color: windowtext; text-decoration: none; text-underline: none;">message</span></a>
and to provide integrity and authenticity assurances on the message. Integrity
assurances detect accidental and intentional message changes, while
authenticity assurances affirm the message's origin.<br />
A MAC <a href="http://en.wikipedia.org/wiki/Algorithm" title="Algorithm"><span style="color: windowtext; text-decoration: none; text-underline: none;">algorithm</span></a>,
sometimes called a <a href="http://en.wikipedia.org/wiki/HMAC" title="HMAC"><span style="color: windowtext; mso-bidi-font-weight: bold; text-decoration: none; text-underline: none;">keyed</span><span style="color: windowtext; text-decoration: none; text-underline: none;"> (<span style="mso-bidi-font-weight: bold;">cryptographic</span>)
<span style="mso-bidi-font-weight: bold;">hash function</span></span></a>
(however, cryptographic hash function is only one of the possible ways to
generate MACs), accepts as input a <a href="http://en.wikipedia.org/wiki/Secret_key" title="Secret key"><span style="color: windowtext; text-decoration: none; text-underline: none;">secret key</span></a>
and an arbitrary-length message to be authenticated, and outputs a MAC
(sometimes known as a <i>tag</i>). The MAC value protects both a message's <a href="http://en.wikipedia.org/wiki/Data_integrity" title="Data integrity"><span style="color: windowtext; text-decoration: none; text-underline: none;">data
integrity</span></a> as well as its <a href="http://en.wikipedia.org/wiki/Authentication" title="Authentication"><span style="color: windowtext; text-decoration: none; text-underline: none;">authenticity</span></a>,
by allowing verifiers (who also possess the secret key) to detect any changes
to the message content.<br />
<br />
<b style="mso-bidi-font-weight: normal;"><span style="font-size: 14.0pt;">Q13. what
is digital signature ?</span></b><br />
<div style="text-align: justify;">
A <span style="mso-bidi-font-weight: bold;">digital
signature</span> is a mathematical scheme for demonstrating the authenticity of
a digital message or document. A valid digital signature gives a recipient
reason to believe that the message was created by a known sender, such that the
sender cannot deny having sent the message (<a href="http://en.wikipedia.org/wiki/Authentication" title="Authentication"><span style="color: windowtext; text-decoration: none; text-underline: none;">authentication</span></a>
and <a href="http://en.wikipedia.org/wiki/Non-repudiation" title="Non-repudiation"><span style="color: windowtext; text-decoration: none; text-underline: none;">non-repudiation</span></a>) and that the message was not
altered in transit (<a href="http://en.wikipedia.org/wiki/Data_integrity" title="Data integrity"><span style="color: windowtext; text-decoration: none; text-underline: none;">integrity</span></a>). Digital signatures are commonly
used for software distribution, financial transactions, and in other cases
where it is important to detect forgery or tampering.</div>

<b style="mso-bidi-font-weight: normal;"><span style="font-size: 14.0pt;">Q14. What is key distribution center ?</span></b></div>
Domain services that use directories for holding account databases and
global catalogs are called key distribution centers. In addition to holding
these databases and catalogs, a key <a href="http://www.wisegeek.com/what-is-a-distribution-center.htm"><span style="color: windowtext; text-decoration: none; text-underline: none;">distribution
center</span></a> uses them to refer to the key distribution centers of other
domains. The idea of the key distribution center is based on cryptography and
is used in computer <a href="http://www.wisegeek.com/what-is-network-security.htm"><span style="color: windowtext; text-decoration: none; text-underline: none;">network
security</span></a>. The cryptography used in these centers is a system of
secret codes that reduces the risk of exchanging keys, which are a form of
information that is <a href="http://www.wisegeek.com/what-is-encryption.htm"><span style="color: windowtext; text-decoration: none; text-underline: none;">encrypted</span></a>
and controls an algorithm’s operation. Oftentimes, this kind of center operates
within a system that allows a limited amount of users access or allows users
access within limited times.<br />
A key distribution center operates using Kerberos™, which is a protocol for
network authentication. These centers ensure secure methods of authentication
when requests are made for a computer network’s services. Generally, the
distribution center operates as follows: a user requests access to particular
services within a computer network, and the center uses encrypted techniques to
authenticate that the user making the request is who he claims to be. The first
request is sent to the server, which sends a notice for the user to
authenticate himself. Upon completing this request, the request is then sent to
a server for ticket granting.<br />

<b style="mso-bidi-font-weight: normal;"><span style="font-size: 14.0pt;">Q15 What
Is Risk Management ?</span></b><br />
<span style="mso-bidi-font-weight: bold;">Risk management</span> is the
identification, assessment, and prioritization of <a href="http://en.wikipedia.org/wiki/Risk" title="Risk"><span style="color: windowtext; text-decoration: none; text-underline: none;">risks</span></a> followed by
coordinated and economical application of resources to minimize, monitor, and
control the probability and/or impact of unfortunate events<sup id="cite_ref-Risk_Management_pg._46_1-0"> </sup><span style="mso-spacerun: yes;"> </span>or to maximize the realization of
opportunities. Risk management’s objective is to assure <a href="http://en.wikipedia.org/wiki/Uncertainty" title="Uncertainty"><span style="color: windowtext; text-decoration: none; text-underline: none;">uncertainty</span></a>
does not deviate the endeavor from the business goals. <br />
Risks can come from different ways e.g. uncertainty in financial markets,
threats from project failures (at any phase in design, development, production,
or sustainment life-cycles), legal liabilities, credit risk, accidents, <a href="http://en.wikipedia.org/wiki/Act_of_God" title="Act of God"><span style="color: windowtext; text-decoration: none; text-underline: none;">natural
causes and disasters</span></a> as well as deliberate attack from an adversary,
or events of uncertain or unpredictable <a href="http://en.wikipedia.org/wiki/Root_cause" title="Root cause"><span style="color: windowtext; text-decoration: none; text-underline: none;">root-cause</span></a>.
There are two types of events i.e. negative events can be classified as risks
while positive events are classified as opportunities. Several risk management <a href="http://en.wikipedia.org/wiki/Technical_standard" title="Technical standard"><span style="color: windowtext; text-decoration: none; text-underline: none;">standards</span></a> have been developed including the <a href="http://en.wikipedia.org/wiki/Project_Management_Institute" title="Project Management Institute"><span style="color: windowtext; text-decoration: none; text-underline: none;">Project Management Institute</span></a>, the <a href="http://en.wikipedia.org/wiki/National_Institute_of_Standards_and_Technology" title="National Institute of Standards and Technology"><span style="color: windowtext; text-decoration: none; text-underline: none;">National Institute of Standards and
Technology</span></a>, actuarial societies, and ISO standards. Methods,
definitions and goals vary widely according to whether the risk management
method is in the context of project management, security, <a href="http://en.wikipedia.org/wiki/Risk_analysis_%28engineering%29" title="Risk analysis (engineering)"><span style="color: windowtext; text-decoration: none; text-underline: none;">engineering</span></a>, <a href="http://en.wikipedia.org/wiki/Industrial_%26_Organizational_Assessment" title="Industrial & Organizational Assessment"><span style="color: windowtext; text-decoration: none; text-underline: none;">industrial processes</span></a>,
financial portfolios, actuarial assessments, or public health and safety.<br />
<br />
<b style="mso-bidi-font-weight: normal;"><span style="font-size: 14.0pt;">Q16
What is PGP ?</span></b><br />
PGP (Pretty good Privacy) is the most widely recognized public key
encryption program in the world. It can be used to protect the privacy of <a href="http://www.wisegeek.com/what-is-email.htm"><span style="color: windowtext;">email</span></a>,
data files, drives and instant messaging.<br />
Traffic on the Internet is susceptible to snooping by third parties with a
modicum of skill. Data packets can be captured and stored for years. Even mail
servers will often indefinitely store messages, which can be read now or at a future
point, sometimes long after the author has changed his or her point of view.
Email, unlike a phone call or letter, is not legally protected as private
communication, and can therefore be read by third parties, legal or otherwise,
without permission or knowledge of the author. Many privacy watchdog groups
advocate, <i>if you aren't using encryption, don't include anything in an
email you wouldn't want to see published.</i> Ideally this includes personal
information as well, such as name, address, phone number, passwords, and so on.<br />
PGP encryption provides privacy missing from online communication. It
changes plain, readable text into a complex code of characters that is
completely unreadable. The email or instant message travels to the destination
or recipient in this cyphered form. The recipient uses PGP to decrypt the
message back into readable form. </div>
