IT framework in PO SUCCESSFUL IT BASED OPERATIONS Support systems Application environment System environment • Routine maintenance • Troubleshooting • Upgrades • Hardware mtce • Peripheral mtce • Network mtce • Server management • Database management • Security • Good quality power supply • UPS maintenance • Generator care

  3. Overview of the tasks • Managing the hardware • Managing the software • Managing the security environment • Managing the support systems

  4. Managing the hardware • Involves • Continuous availability of hardware and peripherals • Availability to user of the system is ensured for the time required to complete the tasks • Security to the equipments • Disaster management • Protection against fire • Protection against natural disasters • Suitable layout to aid smooth transaction flow

  5. Availability of hardware and peripherals • Routine maintenance of all equipments • Proper cleaning • Minimising unnecessary movement • All equipments are put to use continuously • Spare printers to provide redundancy • Numbering the systems and other equipments and keeping the History sheet updated • Equipments to be kept covered while not in use • Preventive maintenance – AMC to be ensured and terms of contract to be understood • Have contact details displayed at prominent places for immediate contact

  6. User – system ratio • Assess the requirement for each user • Plan the layout of the systems in office to ensure equitable distribution • Ensure availability of system for each user according to need • Ensure that no unwanted software (games etc.,) are installed to avoid misuse

  7. Ensuring physical security • Ensure physical security to systems both during working hours and off hours • Server to be installed in a room or rack and kept locked. Entry and exit to be logged • Rooms to be dust free • Rooms to be properly ventilated and free from dampness • Layout to ensure easy access while in use and also for troubleshooting

  8. Ensuring protection • Ensure systems draw power through UPS • Ensure proper earthing • Ensure proper insulations where required • Fire protection - use materials that can fight electrical fire and show leads for use during emergency • Place layout diagram with leads for fire fighting equipments in prominent place and train staff to handle emergency

UPS continued • Power for electrical fixtures not to be drawn from UPS • Test the UPS periodically for committed power supply during power failures • Ensure that UPS and batteries are kept dust free and are not housed in damp environment • Ensure that UPS is kept charged always • Ensure that UPS can protect against surge, spike and over voltage situations

  11. Support system - generators • Ensure that the generator meets the environment conditions • Ensure that the generator is mounted on anti vibrating mountings to prevent damage to structures • Ensure that sufficient diesel is available in stock always • Ensure that generators are turned on immediately after power outage to prevent data loss due to unexpected shut down • Ensure that diesel usage is properly monitored; Maintain a register to watch • Procure the wiring diagram and keep in personal custody • Perform load test once in three months

  12. Managing software environment • Ensure that operating system and SQL server of approved version are installed in the systems • Ensure that automatic updates are turned on to keep the OS and SQL Server periodically updated • Prevent spurious software from being installed in the operating environment • Secure the CDs of operating system and SQL Server and preserve in safe custody personally

  13. Software environment cont’d • Ensure that office staff are aware of minimum troubleshooting and do not rely too much on system administrator • Have a backup system administrator • Have all the staff trained in all applications to ensure continuity of operations in case of turnovers • Through continuous monitoring, prevent unauthorised access • Ensure that all applications are updated with the latest versions and patches

  14. Security issues • Every user including temporary users to have personal user accounts and passwords are changed • The user accounts of users who left the office are not deleted but disabled • Users do not leave the systems without securing their login; Avoid bartering of user accounts • Antivirus protection exists for all systems and are kept updated; Periodic scanning is scheduled
