Introduction
In present era, with rapid growth of banking and financial system throughout
the world.Currently there are more than 730 million Debit/Card circulating
throughout the world. Evesdroppers or Cyber-thief comes with new
measures/attack to perform fraudulent transactions. It has been very
necessary to come up with the proper security measures in ATM transactions
so that people and banks do not suffer the monetary effect of fraudulent
transactions.
Type of Security Attack in Security transactions
These are the common security threats to online/ATm transactions in the
current scenario :-
1.Denial of Service Attack (DoS) [1] is an attempt to make a machine or
network resource unavailable to its intended users. It generally consists of
efforts to temporarily or indefinitely interrupt or suspend services of
a host connected to the Internet.
2.Man in the middle (MITM)attack in network security is kind of active
eavesdropping in which attacker makes independent connections with the
victims and hence transfers relays messages between them, making them
believe they are talking directly to each other.

3.Pre-Play Attack :- It is a cryptographic attack in which an attacker prepares
for the attack in advance by carrying out a simulated transaction while
pretending to be the device to be attacked, and then repeats the attack a
second time with the real device at a time when it is likely to carry out the
same series of operations as in the simulation. The technique relies on being
able to guess the content of the transaction in advance, something usually
made possible by a poor choice of unpredictability within the system
Replay Attack
A replay attack[3] is when an adversary sends copies of a specific packet or
packets to a host for some malicious purpose. In the case of the ATM and
Bank, this malicious purpose could be to drain the ATM of money, debit an
account to zero dollars, or fraudulently transfer money between accounts.
A replay attack is a form of network attack in which a valid data transmission is
maliciously or fraudulently repeated or delayed. This is carried out either by

It is an attack, the attacker continuously trying too many passwords hoping that it was correct.

The first odd network behavior that was reported by the network engineers and the system administrators was an analysis that showed that a single host on the network is opening hundreds of SSH sessions to every single other host on the Aim Higher College’s network every minute. This attacker or hacker is flooding the network with the SSH sessions to bring the web servers down to get some classified information. The second odd behavior was reported that hundreds of hosts are constantly sending SYN packets only to one of the web servers on the Aim Higher college’s campus. Furthermore, this attacker is trying to flood one of the web servers just by
A piece of well-oiled machinery consists of an intricate and complex system: there are well-organized processes, mechanisms within the device work efficiently, and multiple processes function simultaneously to subsequently perform various functions. What happens when there is a glitch in the machine? When there is something wrong, such as connections between intricate processes, which do not follow through, the machine fails to function properly. In some cases, there are not any adjustment or fallback mechanisms. At that point, the damage can be irreversible and the machinery is no longer salvageable. [However, this can illustrate the interactions and processes within the complex machinery.]
ATM is geared toward high speed voice and video transmission, much like a telephone network. It uses a cell-switching and multiplexing technology. The data (this refers to data, voice and video) is transferred between two points on a dedicated circuit in 53 byte cells. Each cell is the exact same size, no matter what data is being sent. The cells consist of 5 bits of header information and 48 bits of actual data. Using a smaller, consistent cell size means there's less delay between when each cell processes at the other end. Using dedicated circuits via virtual circuits ensures there is no interruption in the data transfer. This is extremely important to voice and video transmissions, because they are highly intolerant to data delays. This improves the Quality of Service (QoS) and speed of transfer, which can be between 25 Mbps to 622 Mbps.
It is often disguised to look identical to the original keypad. Overlays allow thieves to capture your PIN number as you enter it, while still allowing the original keypad to receive the PIN number as well. By itself, an ATM overlay is not a tremendous source of identity theft. However, when combined with a mechanism that obtains your card information – such as a skimmer, loop, camera, or other device located at the ATM – a skimmer now allows the identity thief to have access to your bank account, including both your PIN and your debit or credit card number. As a component of ATM theft, ATM Overlay theft contributes to the estimated $1 billion in annual losses banks experience from ATM skimming

According to Sternberg (1999), memory is the extraction of past experiences for information to be used in the present. The retrieval of memory is essential in every aspect of daily life, whether it is for academics, work or social purposes. However, many often take memory for granted and assume that it can be relied on because of how realistic it appears in the mind. This form of memory is also known as flashbulb memory. (Brown and Kulik, 1977). The question of whether our memory is reliably accurate has been shown to have implications in providing precise details of past events. (The British Psychological Association, 2011). In this essay, I would put forth arguments that human memory, in fact, is not completely reliable in providing accurate depictions of our past experiences. Evidence can be seen in the following two studies that support these arguments by examining episodic memory in humans. The first study is by Loftus and Pickrell (1995) who found that memory can be modified by suggestions. The second study is by Naveh-Benjamin and Craik (1995) who found that there is a predisposition for memory to decline with increasing age.

Computer science is a vast field that includes nearly everything relating to computers. Everyday there is information transmitted all over the Internet. Pictures are uploaded, transactions are made on thousands of online retail websites, and banking transactions take place everyday on the Internet. All of these transactions have created a need for secure communications. People wish to keep things like banking, medical, and political information from the eyes of unwelcome parties. This has created a need for cryptography. Cryptography is the science or study of the techniques of secret writing, especially code and cipher systems, and is used by everyone from the average citizen to the government and military.
Cyber Crimes are crimes committed via the Internet. In some cases, the source of attack is the computer system. These types of attacks can come in the forms of computer viruses such as worms or Trojan horses, DOS (denial of service), and electronic vandalism. (OJP, 2013). The computer can also be used to commit theft such as embezzlement, financial information, and fraud. Other uses involves malicious adware, phishing, spoofing, spyware, and hacking; to name a few.
Harmful usage of a sniffer is catching password and also capturing special and private information of transactions, like username, credit ID, account, and password, recording sending of email or messages and resuming the information, Some Sniffers have the ability to modify the computer's information also to the extent of even damaging the system. Weakening the security of a network even being successful in gaining higher level authority. With everyday more and different hackers using of packet sniffers, it has become one of the most important tool in the defence of cyber-attacks and cyber-crime. Writted by (2001 – 2014) Colasoft LLC
