ENTROPY VARIATION ANALYSIS BASED ON

MONITORING DISTRIBUTED DENIAL OF

SERVICEPresented by R.Raghav Sri Ramakrishna Engineering CollegeR.Prabhu(III BE-ECE )KGISL Institute of Technology

OBJECTIVE

• A Denial of Service (DoS) attack is a malicious effort to keep authorized users of a website or web service from accessing it, or limiting their ability to do so

• DDoS attacks make a networked system or service unavailable to legitimate users.

3

EXISTING SYSTEM

• The network security community does not have effective and efficient traceback methods to locate attackers

4

DRAWBACKS

• We come to know that the message which has been sent is hacked only after the hacking has been done by the intruders or any other users

• So there is no use in receiving just simply an alert message after our information is hacked

5

PROPOSED SYSTEM

• In this process we would come to know before the hacking is being done

• If any attempt is made by the intruder to hack the data

6

SOFTWARE REQUIREMENTS

• Operating system :Windows XP • Front End : MS Visual

Studio• Back End : MS-SQL server

7

HARDWARE REQUIREMENTS

• Processor : Dual Core• Internal memory : 2GB • Hard Disk Drive : 40 GB

8

FUTURE ENHANCEMENTS• To implement this project in a wider

network, that is in MAN and WAN

22

SOCIAL NETWORK

• Twitter said attackers compromised 250,000 account.

• Twitter has reset those users’

passwords and sent e-mails.

CURRENT AFFAIR
