Rogō is designed to only accept connections from secure (HTTPS) connections. This means that all data sent between the client and the server is encrypted using 128- or 256-bit SSL. Any malicious hacker trying to read the data will only get encrypted and unreadable data. This secure connection exists for all Rogō activities whether staff or students and on or off campus.
Although it should be possible install Rogō on a Windows server, it has always been used at the University of Nottingham and other partners on Linux/Solaris servers. Operating systems of this type are less susceptible to viruses and other attacks and so there is less chance of a problem during a high-stakes exam.
Note: It is important that any assessment server, regardless of the applications software chosen, is setup correctly, has no unnecessary ports open, has virus checking and firewalls installed and is correctly patched.
Rogō has been designed to encourage the reuse and sharing of material within module teams. Folders, papers and individual questions are assigned to module teams to allow access to all team members for viewing and editing. Staff can be assigned to multiple teams and teams can be of any size.
Most of Rogō cannot be accessed by students. The majority of the scripts are used for managing papers, questions, folders, teams, reports, etc. The only parts a student can access are the student help system and actual assessment and survey papers. However, within a paper it is often necessary to restrict access further, especially for summative examinations. Restrictions to papers can be made using any combination of the following:
- by date/time
- by Degree
- by Academic Year of Study
- by IP Address
At the lowest level of security Rogō will prevent users from trying to select more options than are permitted.
For example, in the question shown on the right hand side of the page only two answers are required but the user has tried to tick more. After the user clicks on the OK button Rogō will uncheck the last selected checkbox.
Similar checks are placed on ranking questions to ensure that users do not include duplicate ranks in their answers.
