System Development and Maintenance

Points to consider

Overview	Component	Situation	Evidence
Frequency of changes	A	Often changes are required for various reasons (e.g. functionality enhancement changes in business processes, etc.)
Frequency of changes	OS, DB	Changes are made for each release of security patches/upgrades
Frequency of changes	N, O	Changes are made for each release of patches/upgrades

Assessment of Design Effectiveness

No.	Question	Component	Situation	Evidence
1	Policies and procedures for development and maintenance are described in a formal way	A, OS, DB, N, O	Documentations are prepared by the IT team and authorized by the head of IT
2	Roles and responsibilities concerning development and maintenance are clearly defined	A, OS, DB, N, O	IT personnel incl. service vendors perform changes
3	Changes are tested and their results are approved	A, OS, DB, N, O
4	Changes are approved for their migration to the production environment
5	Procedures are in place for preventing/detecting unauthorized changes to the production environment

System Security (Access Control)

Points to consider

Question	Component	Situation	Evidence
Number of users	A	Large number of users in large number of user locations/departments
Number of users	OS, DB, N, O	Number of users and user locations/departments is limited
Frequency of "direct data change" ("direct data change" means to change data with the utilities such as SQL software)	N	No direct change to data has been required since its implementation, as the system has been in stable operation

Assessment of Design Effectiveness

No.	Question	Component	Situation	Evidence
1	User authentication is required	A, OS, DB, N, O	User-ID and password are assigned on an individual basis
2	User and access rights granted to each user are documented	A	A list of users is prepared with the rights granted to each user. This list is generated from the system
2	User and access rights granted to each user are documented	A, OS, DB, N, O	A list of users is prepared with the rights granted to each user
3	Policies and procedures for user-ID administration (add, change, remove, and periodic user validation) are described in an authorized documentation	A, OS, DB, N, O	The documentation is prepared and authorized by the head of IT
4	Periodic user validation is performed, this means each user's access rights are reviewed on a periodic basis	A, OS, DB, N, O	Performed both in terms of existence of user and the detailed access rights granted to each user-ID on an annual basis by the head of IT
5	User-ID administration requests are approved by managers in user dpt. and/or IT dpt, as appropriate	A, OS, DB, N, O	Records are maintained in the change management
6	Access to privileged IT functions is restricted to appropriate personnel	A, OS, DB, N, O	These functions are restricted to IT personnel. Logs of the use of such privileged user-IDs are reviewed annualy
7	The level of complexity in password settings are appropriate	A, OS, DB, N, O	Password complexity is configured based on a minimum length of 8, at least one upper case letter, at least one lower case letter, at least one special character and at least one numeric value. Password changes must happen every 3 months
8	Policies and procedures for direct change to data are descripted in a documentation	DB	Only the head of IT may perform and authorize direct changes to the data
9	Direct change to data are authorized	DB	No direct changes to data where made
10	Direct change to data are tested	DB	No direct changes to data where made
11	Access to DB and/or utilities for direct change to data is restricted to appropriate personnel	DB	Only the head of IT has write/change permissions to the DB
12	Physical access to computer hardware is restricted to appropriate personnel	A, OS	Data and programs are in a stand-alone PC in control of the user. User permissions for Applications and OS are restricted appropriately
12	Physical access to computer hardware is restricted to appropriate personnel	DB	Server(s) are located in a machine room with appropriate physical access control

System Operation and Administration

Points to consider

Question	Situation	Evidence
Frequency of problems/incidents	Material failure such as miscalculation or malfunction of the system has not occurred.
Frequency of changes to job schedules	Changes to job schedules occur frequently but most of them are those in execution date
Frequency of Non/Scheduled job	Non/Scheduled job is required in some cases but its frequency is low

Assessment of Design Effectiveness

No.	Question	Situation	Evidence
1	Policies and procedures for backups	Exists
2	Completion of backup is ensured	All backup job records are reviewed by monitoring personnel
3	Backup and recovery are periodically tested
4	Policies and procedures for job operation are described in a documentation
5	Job schedule changes are approved
6	Procedures are in place for preventing/detecting unauthorized changes to job schedules
7	Completion of job execution is ensured
8	Requests for non-scheduled job execution are authorized
9	Policies and procedures for identifying, resolving, reviewing, and analyzing IT operations problems or incidents are described in a documentation
10	IT operations problems or incidents are identified, resolved, reviewed, analyzed, and follow-ups are evidenced in a timely manner

Outsourcing Contract Management

Points to consider

Question	Situation	Evidence
What services are outsourced	Some of the services are outsourced concerning development/maintenance related to ITGCs

Assessment of Design Effectiveness

No.	Question	Situation	Evidence
1	Outsourced service are clearly defined and agreed with the service vendor in writing e.g. in contract and/or SLA
2	Service vendor's compliance to the service level is periodically reviewed
