Extract of sample "Integrating Security and Usability into the Requirements and Design Process"

Download file to see previous pages The user interface design of the touch screen register has features that enable it to attain security. First, the new system enforces access controls by requiring that every cashier supplies a matching pair of user-id and password in order to log in to the register. It is not only helpful in preventing non-legitimate access to the register, but also provides a good avenue to introduce role-based authentication. Moreover, it will be possible associating a given cashier with a certain workstation, and in certain instances, it is possible associating a cashier with a certain workgroup. Second, the registers ability to lock after four unsuccessful login attempts is a good strategy to suppress the efforts of brute force attackers and malicious insiders who will constantly use trial and error in a bid to gain unauthorized access to the system. Further, the safety of information stored therein is enhanced by the condition that only the managers can use a keycard to unlock the register following unsuccessful login attempts. Finally, unauthorized access is also prevented by the registers ability to lock if the screen does not get touched for a period of three minutes.
The system also features certain security utilities that to some extent collide with the usability. First, the restriction that only the cashier who was authenticated before the system locked will be in a position to unlock it is a feature that prevents the idea of other end-users performing malicious acts on other peoples account profile. Otherwise, new cashiers would need to restart the system. The tool also increases accountability whilst enhancing the systems intention to associate every action with a particular user (Wysocki, 2013).  ...Download file to see next pagesRead More

This action can be achieved when divergent thinking and convergent thinking are coalesced with the help of spray diagrams, multiple cause diagrams, etc. Next, systems level designs and techniques must be produced. After that, the implementation scheme must be verified with the help of the techniques like software and hardware testing, validation, etc. Finally, the designing team must adhere to the most flexible “Systems Engineering policies, processes and tool sets” (Alston and Campbell, 112) that can be used and modified during security emergencies.

...of ‘defensible space’. Challinger (2008) stipulated that crime rate with reference to buildings increased as the number of floors increased. The other concept as far as design is concerned is the Crime Prevention Through Environmental Design (CPTED). Environmental factors make crime easier or harder to happen. Situational crime prevention is also a fact under design of the building. A modification of environmental factors has to be made to reduce crime in the building. In the case of CPTED, all the workers in the building will be required to be aware of their situations and be responsible for these situations. For this purpose, taking care of design...
