In future this operation of Gail Gas Limited (GGL) will expand to more Geographical area of cities in India; 30 cities are expected to be added in next five years. To facilitate the operation, monitoring, control, maintenance, supervision and management of the City Gas Distribution (CGD) network, the SCADA (Supervisory Control & Data Acquisition) system function is to provide safe and efficient operation of the pipeline and facilities with the minimum of manned intervention. The SCADA system operation shall be based on a 24 hour per day, 365 day per year schedule. Each city gas distribution network is primarily distributed among following major categories.

1. City Gate Station (CGS) 2. Industrial Metering System 3. Medium Industries and Commercial Metering System 4. CNG Stations.

CGS: GGL receives Natural Gas from GAIL inside the particular city and CGS is interface station between the GAIL Main Natural Gas Pipeline and GGL city gas distribution (CGD) network.

CNG Stations: There are two categories of CNG stations: a. Online CNG Stations – On line stations are connected to the pipeline and have high compression capacity. These stations supply CNG to both vehicles and daughter stations (through mobile cascades). Typically, they have the facility of filling all types of vehicles – buses, autos, cars etc. these CNG station comprises of compressors, dispensers, storage cascades and Facility for filling the mobile cascades. These stations are also classified as Mother Stations.

b. Daughter Stations – the Daughter Station dispenses CNG using mobile cascades. These mobile cascades at daughter stations are replaced when pressure falls. Pressure depleted mobile cascade is refilled at the Mother Station. There is reduction in storage pressure at daughter station with each successive filling.

9.11 System Security Requirements

The SCADA system shall be provided with a security / access management system to restrict access to authorized users only. The security / access management shall apply to all SCADA workstations, MCC, SMCC and Web based terminal access sessions. Multiple security access levels shall be provided to allow differentiation of privileges for the following as a minimum: • Casual user (view only) • Operator (can issue commands via MMI system) • MCC operator • Maintenance and support staff (can make changes to SCADA database). • System supervisor (have access to program files and can make system level changes)

Security Configuration The security provided for the SCADA system can be described as follows:

1. Windows operating system security. 2. Station security

Windows Operating system security

To prevent an operator from accessing the operating system and software other than SCADA station software, the operator station SHALL be configured as a secure station through setup Windows 2000 operating system security.

For example, the following security will be setup through Windows 2000 Local Security Policy and System Registry:

Page 37 of 175

Document No. Rev

11- 0290- 02-11- 02- 002 A

GAIL GAS LIMITED


SHEET 28 of 95

� Setup operator automatic logon � Create a batch file which starts station automatically � Prevent operators from shutting down their computer � Remove access to applications via Task Manager and Windows Explorer � Prevent users from locking the computer

Station security When you build a Station, you define the security method that will control access to functions at that Station. You choose between:

• Station-based security

• Operator-based security

Station-based security Station-based security works as follows:

• Station starts without prompting users to enter any form of operator ID or

password.

• The initial security level setting allows users to perform the basic operating

functions associated with the user level of Oper (for example, acknowledging

alarms and controlling points).

• Users only need to use a password if they want to change to a higher level of

security.

• Asset assignment applies to the Station, not to the operator.

Operator-based security Operator-based security provides a higher level of security than Station-based security. In general, Operator-based security with traditional operator accounts shall work as follows:

• GAIL GAS LIMITED will assign a specific security level to each user.

• Users cannot access any Station functions unless they enter a valid ID and

password.

• To access a higher security level than the one they are currently using, users need

to sign off and sign on again as a different operator who has the higher security

level.
