An Cyber Gate Defense security consultant recently worked with a customer to develop a tool for controlling and monitoring critical systems for their 24 x 7 Network Operations Centre (NOC). The consultant worked with key stakeholders including end user and design architect to guide the engineers and developers to determine what requirements were necessary to ensure a secure and functioning product which needed to reside on the network. The tool enabled the client to create digital certificate easily without the need to use KeyTool included in Java Components. The KeyTool is very useful but do not have the GUI application, so users felt uncomfortable using it. We developed the GUI application which works on KeyTool.
