Abstract: Security in the ATM Network is very necessary because it is widely spread in all
areas such as financial, network administration and other important parts of financial
network which requires very sensitive handling transmission of data. Manipulating the
transmitted data, spoofing and misuse of ATM channels would be very fatal in accounting
system. Mostly the ATM transactions should rely on the integrity of secure Crypto-processor
(Dedicated processor for carrying Crypto- graphic operations). Therefore the ATM Forum,
developed new standards & specification called ATM security specification 1.0 in 1998 and
then in March 2001, the ATM Forum developed a new Technical Committee called ATM
security & specification version 1.1. This paper presents the safety & security of the
Automated Teller Machine which includes the basic introduction, threats to an ATM
network, network security framework
