Abstract- In this work, we are dealing with service oriented applications which are based on service oriented architecture style. Also, we are interested on the large scale reuse paradigm which deals with a service line. This former envisions a family of similar service oriented applications. This approach promise gain in productivity and time to market. Combining SOA and service line is called SOPL (Service Oriented Product Line). The services which are autonomous play a fundamental role in SOPL. Assuring secure services is vital in establishing a climate of trust and confidence between Internet users and services providers. In this context, this paper deals with an attempt to extend the SOPL phases with security activities in order to produce secure service oriented applications as a result of a secure development process lifecycle.

Abstract- The success of an e-government initiative depends on different factors such as economic strategies, countries political and decisions initiatives, etc. Also the siloed nature and technical aspects can hamper progress. We concentrate in this paper on architectural design of e/m-government systems according to a software engineering point of view which among all other considerations promises the success of the final e/m-government operational platform. We propose an architecture based on a systematic, large scale reuse which seems to be appropriate for the so many applications proposed as services to citizens in the context of e/mgovernment. We specifically adopt the Service Oriented Product Line approach. Existing e-government software architectures consider reuse but not large scale reuse as in Product Line Engineering which promises improvements in productivity, time-to-market, quality, and cost. The Service Oriented Architecture is adopted by a lot of e-government systems and SOPL takes the advantages of both SOA and PLE.
