2. Compromised machines are one of the key security threats which often
leads to attacks such as spamming,spreading malware , DDos and identity
theft.
These machines which are involved in the spamming activities, called as
spam zombies are detected by using spam zombie detection system named
SPOT.
SPOT is designed based on powerful statistical tool called sequential
probability ratio test (SPRT).

3.  In the existing system , compromised machines have been increasingly
used to launch various security attacks.
 Better suited for understanding the aggregate global characteristics of
spamming botnets.
Drawbacks:
‣ Online detection requirement in the network is not supported.
‣ Focus on point of infection.
‣ Analyses the rate at which messages are sent.

4.  We focus on detection of compromised machines commonly referred as
spam zombies in the network.
 We aim to develop a tool for automatically detecting the compromised
machines in an online manner.
 Detects compromised machines quickly and accurately, with low false
positive and false negative rates.

TCP is a connection-oriented protocol and reliable.
UDP (User Datagram Protocol) is a connectionless and unreliable
protocol.

10. •Microsoft Open Database Connectivity (ODBC) is a standard
programming interface for application developers and database systems
providers.
•The beauty of ODBC is that the application can be written to use the same
set of function calls to interface with any data source, regardless of the
database vendor.
•In an effort to set an independent database standard API for Java, Sun
Microsystems developed Java Database Connectivity, or JDBC
• The consistent interface is achieved through the use of “plug-in” database
connectivity modules, or drivers.
•If a database vendor wishes to have JDBC support, he or she must provide
the driver for each platform that the database and Java run on.

22.  After finishing the development of any computer based system
the next complicated time consuming process is system testing
 Software testing is an important element of the software
quality assurance and represents the ultimate review of
specification, design and coding.
Testing Objectives
Testing is a process of validating and verifying that a product:
oMeets the requirements
oWorks as expected
oCan be implemented
oPacifies the needs of customer
A good test case is one that has a high probability of finding an
undiscovered error.

23.  Source code testing
 Specification testing
 Module level testing
 Unit testing
 Integration testing
 Validation testing
 Recovery testing
 Performance testing
 Black box testing
 Output testing
Testing Methods
Graphical Analysis in the year 2013

24. The protection of computer based resources that include
hardware, software, data, procedures and people against
unauthorized use or natural disaster is known as system security.
System security can be divided into four related issues:
oSystem security
oData security
oPrivacy
oSystem Integrity
oConfidentiality

25. Based on various test and survey results which are depicted in the
form of tabular columns below it can be concluded that SPOT
outstands other detection algorithms.
It has been an immense pleasure on working on this project which
comes under Network Security domain which is the need of the hour
in this technology driven world.
