Introduction
What is Cyber Crime?
Computer crime, or cybercrime, is crime that involves a computer and a network. The computer may have been used in the commission of a crime, or it may be the target.
What is Cyber Security?
C
yber security, also known as computer security or IT security, is the protection of information systems from theft or damage to the hardware, the software, and to the information on them, as well as from disruption or misdirection of the services they provide. It includes controlling physical access to the hardware, as well as protecting against harm that may come via network access, data and code injection and due to malpractice by operators,whether intentional, accidental, or due to them being tricked into deviating from secure procedures.
The field is of growing importance due to the increasing reliance on computer systems in most societies and the growth of "smart" devices,including smartphones, televisions and tiny devices as part of the Internet of Things – and of the Internet and wireless network such as Bluetooth and Wi-Fi.
Some organizations are turning to big data platforms, such as Apache Hadoop, to extend data accessibility and machine learning to detect advanced persistent threats.
Vulnerabilities and Attacks
Vulnerability is a system susceptibility or flaw, and much vulnerability are documented in the Common Vulnerabilities and Exposures (CVE) database and vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities as they are discovered.
An exploitable vulnerability is one for which at least one working attack or "exploit" exists.
To secure a computer system, it is important to understand the attacks that can be made against it, and these threats can typically be classified into one of the categories below.
The internet is growing rapidly. It has given rise to new opportunities in every field we can think of be it entertainment, business, sports or education.
There’re two sides to a coin. Internet also has it’s own disadvantages is cyber crime- illegal activity committed on the internet.
In this PowerPoint presentation, you can understand the basics of cybersecurity such as how cybersecurity emerged, know about cyber threat evolution, types of cybercrime, how to take preventive measures in order to control the threats, learn various security reasons as well as methods.

A ROBUST MECHANISM FOR DEFENDING DISTRIBUTED DENIAL OF SERVICE ATTACKS ON WEB...IJNSA Journal
Distributed Denial of Service (DDoS) attacks have emerged as a popular means of causing mass targeted service disruptions, often for extended periods of time. The relative ease and low costs of launching such attacks, supplemented by the current inadequate sate of any viable defense mechanism, have made them one of the top threats to the Internet community today. Since the increasing popularity of web-based applications has led to several critical services being provided over the Internet, it is imperative to monitor the network traffic so as to prevent malicious attackers from depleting the resources of the network and denying services to legitimate users. This paper first presents a brief discussion on some of the important types of DDoS attacks that currently exist and some existing mechanisms to combat these attacks. It then points out the major drawbacks of the currently existing defense mechanisms and proposes a new mechanism for protecting a web-server against a DDoS attack. In the proposed mechanism, incoming traffic to the server is continuously monitored and any abnormal rise in the inbound traffic is immediately detected. The detection algorithm is based on a statistical analysis of the inbound traffic on the server and a robust hypothesis testing framework. While the detection process is on, the sessions from the legitimate sources are not disrupted and the load on the server is restored to the normal level by blocking the traffic from the attacking sources. To cater to different scenarios, the detection algorithm has various modules with varying level of computational and memory overheads for
their execution. While the approximate modules are fast in detection and involve less overhead, they provide lower level of detection accuracy. The accurate modules employ complex detection logic and hence involve more overhead for their execution. However, they have very high detection accuracy. Simulations carried out on the proposed mechanism have produced results that demonstrate effectiveness of the proposed defense mechanism against DDoS attacks.
Impact of Flash Crowd Attack in Online Retail ApplicationsIJEACS
Now days the usage of internet has been enormously
increased. Online shopping has acquired widely in day today
event. Mean which these online shopping is affected by various
advanced network security attacks Flash Crowd Attack is the one
of the advanced attack, where huge amount of dummy requests
are sent at a time and thus putting lot of pressure on server
machine and degrade the efficiency. Also authorized client can’t
receive the acknowledgement notification. We found that this
attack might cause lot of problems to online buy user in the
coming days. This paper depicts the minimization Flash Crowd

DISTRIBUTED DENIAL OF SERVICE (DDOS) ATTACKS DETECTION MECHANISMijcseit
Pushback is a mechanism for defending against Distributed Denial-of-Service (DDoS) attacks. DDoS attacks are treated as a congestion-control problem, but because most such congestion is caused by malicious hosts not obeying traditional end-to-end congestion control, the problem must be handled by the routers. Functionality is added to each router to detect and preferentially drop packets that probably belong to an attack. Upstream routers are also notified to drop such packets in order that the router’s resources be used to route legitimate traffic hence term pushback. Client puzzles have been advocated as a
promising countermeasure to DoS attacks in the recent years. In order to identify the attackers, the victim server issues a puzzle to the client that sent the traffic. When the client is able to solve the puzzle, it is assumed to be authentic and the traffic from it is allowed into the server. If the victim suspects that the
puzzles are solved by most of the clients, it increases the complexity of the puzzles. This puzzle solving technique allows the traversal of the attack traffic throughout the intermediate routers before reaching the destination. In order to attain the advantages of both pushback and puzzle solving techniques, a hybrid scheme called Router based Pushback technique, which involves both the techniques to solve the problem of DDoS attacks is proposed. In this proposal, the puzzle solving mechanism is pushed back to the core routers rather than having at the victim. The router based client puzzle mechanism checks the host system whether it is legitimate or not by providing a puzzle to be solved by the suspected host.

Enhancing the impregnability of linux serversIJNSA Journal
Worldwide IT industry is experiencing a rapid shift towards Service Oriented Architecture (SOA). As a
response to the current trend, all the IT firms are adopting business models such as cloud based services
which rely on reliable and highly available server platforms. Linux servers are known to be highly
secure. Network security thus becomes a major concern to all IT organizations offering cloud based
services. The fundamental form of attack on network security is Denial of Service. This paper focuses on
fortifying the Linux server defence mechanisms resulting in an increase in reliability and availability of
services offered by the Linux server platforms. To meet this emerging scenario, most of the organizations
are adopting business models such as cloud computing that are dependant on reliable server platforms.
Linux servers are well ahead of other server platforms in terms of security. This brings network security
to the forefront of major concerns to an organization. The most common form of attacks is a Denial of
Service attack. This paper focuses on mechanisms to detect and immunize Linux servers from DoS .

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

4. WHO IS BEHIND THIS?
Hacker group "Anonymous"
STATE-RUN TELECOM MTNL's WEBSITE MUMBAI WAS HACKED BY A
PAKISTANI HACKER OPERATING FROM Palestine Australia.
Mr.Creepy
from Napsters CrEw
5. TYPE OF ATTACK
• Anonymous took down the MTNL website through a massive
Distributed Denial of Service (DDoS) attack.
• WHAT IS DDOS?
• A Distributed Denial of Service (DDoS) attack is an attempt to make an
online service unavailable by overwhelming it with traffic from
multiple sources.
• After the attack, MTNL's corporate website could not be accessed.
6. •How DDoS Attacks Work
• According to this report on eSecurityPlanet, in a DDoS attack, the
incoming traffic flooding the victim originates from many different
sources – potentially hundreds of thousands or more. This effectively
makes it impossible to stop the attack simply by blocking a single IP
address; plus, it is very difficult to distinguish legitimate user traffic
from attack traffic when spread across so many points of origin.
7. •The Difference Between DoS and DDos Attacks
• A Denial of Service (DoS) attack is different from a DDoS attack. The
DoS attack typically uses one computer and one Internet connection
to flood a targeted system or resource. The DDoS attack uses multiple
computers and Internet connections to flood the targeted resource.
DDoS attacks are often global attacks, distributed viabotnets.
8. HOW TO HACK? & WHAT TO DO?
• The attacker hacked the website with a Remotely Administrated
Trojan (RAT) written in a Perl script. Perl is a high-level scripting
language supporting the UNIX operating system, which is a computer
operating system like Windows and MacOS.
• The script was used to hold an executable code that delivered specific
functional commands of the attackers via a command and control
(CnC) server.
9. • This particular RAT came with a server and client file, and attached
itself to an empty port in MTNL’s systems, making the server file
‘listen’ to incoming connections and data going through the ports.
When someone ran the client file, it gave out the IP address and the
trojan starting receiving commands from the attacker and running
them on MTNL computers,”.
• when an MTNL employee clicked on the file that may have arrived as,
say, an innocuous email, the trojan downloads itself onto the system
and enters MTNL’s internal command centre, allowing the attacker to
take control of the user database.
10.
11. • The Napsters Crew also operate a Facebook profile called ‘CreepAt
Localhost’ where they have put up amessage that reads, “Lol, just
rooted MTNL server, feeling excited”. In another Facebook message,
the group said, “I told you, I am back and unstoppable.
• Hacked homepage if in cache of that customer, should be refreshed,
otherwise it will continue to show old page," MTNL spokesperson had
said.
13. • The hacked sites also carried a picture of a young
Pakistani posing with an inappropriate hand gesture
and face painted with the colour of Pakistan’s National
flag with Indian soldiers holding the tricolour standing
in the background.
14. HOW MANY WEBSITES HACKED BY
ANONYMOUS?
• http://delmarefoods.com/ (Still defaced)
• http://iilgroup.com.pk/ (Still defaced)
• http://inceptapharmapk.com/ (Still defaced)
• http://xoniacream.com/ (Still defaced)
• http://skincarepakistan.com/ (restored)
15. CONCLUSION/RESULT
• AFTER DDOS ATTACK FIRST KEEP SHUT DOWN SITE IMMEDIATELY.
• BUILD LAYER SECURITY AROUND YOUR SITE
• SWITCH TO HTTP
• USE STRONG PASSWORD AND CHANGE REGULARLY
