  1. IT System for CIMSS, IISc • By the IT Subcommittee of the CIMSS Project • Jayant Haritsa (SERC) • R. Krishnamurthy (SERC) • Anurag Kumar (ECE, Convener) • V. Kumaran (Chem. Engg.) • Y.N. Srikanth (CSA) • V. Vinay (CSA) IT System for CIMSS, IISc

  2. IT System Functions • System users • faculty, admin officers, and case workers • Document preparation, movement, storage, access and manipulation • Implementation of office workflow • e.g., indent “flows” from faculty to chairman to purchase to audit,…etc. • authentication, annotation, and signatures at each step • tracking of workflows • The “IT System” is the platform on which these functions are implemented IT System for CIMSS, IISc

  3. Design Considerations • Client independence • variety of hardware and operating systems on campus • system should not be client dependent • Difficult to maintain security and integrity of multiple servers in multiple locations • power supply, air-conditioning, cleanliness, etc. • Work should not actually flow to the clients • messy to recover from client crash • harder to track status of work • Aim for completely paperless system IT System for CIMSS, IISc

  4. Design Decisions • Web based client server interaction • clients only need a web browser • plug -ins needed for digital signatures, and document upload • Central server • with redundant hardware and storage • in a well prepared site • All data and work-in-progress resides in data-base in central server • workflow implemented by manipulating references to the documents IT System for CIMSS, IISc

  5. CIMSS Network Architecture CIMSS central server Proposed systems Typical admin workstation client Scanner and fax modem Server LAN Server LAN firewall Admin LAN Typical dept. LAN Campus network backbone (optical fibre) Existing systems client Scanner and fax modem IT System for CIMSS, IISc

  6. CIMSS Central Server Off-the-shelf proprietary Programmable/configurable application software Server machine Web server with security features Workflow software and database management system Secure socket layer Redundant disks with CIMSS database Standard UNIX system TCP/IP UNIX operating system CIMSS server LAN to/from campus LAN IT System for CIMSS, IISc

  7. Virtual Workflow CIMSS central server Requests, and data entry forms Faculty member Requests, and data entry forms Requests, data entry forms Work does not “flow” between server and clients; only references change in data-base Admin officer Case worker IT System for CIMSS, IISc

  8. Layers of Security client central server web browser with authentication plugin web server with public key certificate server digital signatures authenticated login; secret key session security, with key aging secure socket layer secure socket layer firewall blocks unauthorised packets fingerprint-based security for console access campus network IT System for CIMSS, IISc

  9. Product Selection (Hardware) • Central CIMSS server • SUN Ultra Sparc 450, with Solaris (UNIX) • redundant disk drives (RAID) • redundant power supply, ethernet controller, disk controller • Firewall • Cisco PIX • proprietary hardware and operating system • high performance • Clients • PCs with Windows 95/98, NT • PCs with Linux • Standard UNIX workstations IT System for CIMSS, IISc

  10. Product Selection (Software) • Data base system • ORACLE enterprise server • Workflow definition software • ORACLE workflow • Web server • NETSCAPE • Public key server (Certification Authority) • included in the NETSCAPE server • Client web browser • Netscape or (MS) Internet Explorer IT System for CIMSS, IISc

  11. Application Development • Server software • implementation of workflows • development of forms and interfaces • Client software • browser plug-ins for supporting: • digital signatures • upload of scanned documents (e.g., quotations) IT System for CIMSS, IISc

  12. Some Implementation Concerns • Central server location • stable power supply • prevention of fire, dampness, lightning strike, etc. • Data back-up • back-up copies should be stored in separate site • Security and authentication • at present only 40-bit security available, owing to US export restrictions • this should be upgraded as and when available • key-aging, within sessions, is an interim solution IT System for CIMSS, IISc

  13. Vendor Selection • First round of vendor proposals • Tata Consultancy Services • CMC • Planetasia • Faculties India • Tata Infotech • Logic Point • Short list; second round • Planetasia • Tata Infotech • Final negotiations are under way with • Tata Infotech IT System for CIMSS, IISc
