TANGIBLE SECURITY




TRANSACTIONAL SECURITY
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.
THREATS

Threat A: Internet Protocol Worms

Threat B: IP Network
  Disruption/Denial of        Services

Threat C: Data Collection for
  Malicious              purposes
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)
How it works

    CONSUMER




                GATEWAY
               (For verification)




                                    BANK
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).
Advantages

Revenue opportunities:
High performance via
hardware switching.

Dynamic bandwidth for
bursty traffic.
Disadvantages
Processing overhead as messages are segmented
 into cells


Segmentation mismatch, as the last cell in a
 fragmented message may not be fully used.
Pin Capturing
   Personal Identification Number (“PIN”) capturing is a
    worldwide problem.
   PIN capturing refers to a method of strategically
    attaching
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)
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.
ATM Errors
1.   Notify the bank or ATM owner.
2.   Act quickly.
