System Support & Security Phase
Managing systems support and security involves
three main concerns:
– user expectations
– system performance
– security requirements .
User Support
Companies provide user support in many forms, including user training and a help desk to provide technical support and assistance.
User Training
User Training Package
Depending on the nature of the changes, the package could include online support via e-mail, a special Web site, a revision to the user guide, a training manual supplement, or formal training sessions.
Help Desks
A help desk is a centralized resource staffed by IT professionals who provide
users with the support they need to do their jobs.

Provide answers to technical or operational questions
Make users more productive by teaching them how to meet their own information needs.
Types Of Maintenance
Maintenance activities include:
Changing programs, procedures, or documentation to ensure correct system performance.
Adapting the system to changing requirements; and making the system operate more efficiently.
System Maintenance Tools
Many CASE tools include system evaluation and maintenance features, including
the following examples:
• Performance monitor that provides data on program execution times
• Program analyzer that scans source code, provides data element cross-reference information, and helps evaluate the impact of a program change
• Interactive debugging analyzer that locates the source of a programming error
• Reengineering tools
• Automated documentation
• Network activity monitor
• Workload forecasting tool
System Security
System security refers to protecting the system from theft, unauthorized access and changes, and accidental or accidental harm. In automated systems, security involves protecting all the parts of computer system which includes data, software, and hardware. systems security includes system privacy and system integrity
BACKUP AND RECOVERY
