This document provides an overview of ATM components, security features, and operations. It discusses the hardware and software used in ATMs, including tangible security mechanisms like stainless steel housings and time-delay locks. Threats like worms and denial of service attacks are described along with prevention methods like firewalls and network separation. The document explains how ATM transactions work through the consumer, gateway, and bank network. It also covers functions, advantages, disadvantages, and common errors.

3. ATM Definition
Asynchronous Transfer Mode
(ATM)
A high-performance, cell-oriented switching and multiplexing
technology that utilizes fixed-length packets to carry different types
of traffic.

4. COMPONENTS
Hardware
Software

5. HARDWARE
CPU
Magnetic/Chip reader
Display: Touch screen or with
function keys
Crypto processor
Record Printer
Vault

6. Software
Front End: OS2, Linux, Unix, MS Windows
Firmware (coded in
C++/Java)
Back End: DBMS – Oracle, MS SQL
Server etc
(Distributed databases
situated at the bank’s sites)

7. Security
TANGIBLE SECURITY
TRANSACTIONAL SECURITY

8. TANGIBLE
SECURITY
1.Stainless steel housing and a mechanical box
2.Time-delay lock box.
3.GPS enabled network.
4.Installation of CCTVs.
5.Security Guards.

9. THREATS
Threat A: Internet Protocol Worms
Threat B: IP Network
Disruption/Denial of Services
Threat C: Data Collection for
Malicious purposes

10. THREAT
PREVENTION
 THREAT
 PREVENTION
A (Nachi worm)
 Installing software based firewall
B (sapphire worm)
 Separation of ATM from Public Internet (patch management)
 Virtual and physical separation of ATM
 Networks (VPN)

12. ATM Functions
Service is connection oriented, with data transferred
over a VC
A cell-switched network (architecture).
Fixed-size cell (53-Bytes)
Uses Asynchronous time-division multiplexing
(Asynchronous TDM).

13. Advantages
Revenue opportunities:
High performance via
hardware switching.
Dynamic bandwidth for
bursty traffic.

14. Disadvantages
Processing overhead as messages are segmented
into cells
Segmentation mismatch, as the last cell in a
fragmented message may not be fully used.

15. Pin Capturing
 Personal Identification Number (“PIN”) capturing is a
worldwide problem.
 PIN capturing refers to a method of strategically
attaching

16. ATM Commands
 Command Description atm filter-expr
 Configures an ATM address filter that matches patterns.
 atm filter-set
 Creates an ATM address filter set.
 show atm filter-expr
 Displays a specific ATM filter expression or a summary
ATM filter expression.
 show atm filter-set
 Displays a specific ATM filter set or a summary ATM filter
set.
 atm accounting (interface)

17. ATM Networking
 ATM Devices and the Network
environment.
 ATM is a cell-switching and
multiplexing technology that
combines.
 The benefits of circuit switching
(guaranteed capacity and
constant.

18. ATM Errors
1. Notify the bank or ATM owner.
2. Act quickly.
3. Link down.
4. Amount deduct from account but did not come
out from atm machine.
