Recognising user's risky behaviours in real-time is an important element of providing appropriate solutions and recommending suitable actions for responding to cybersecurity threats. Employing user modelling and machine learning can make this process automated by requires high-performance intelligent agent to create the user security profile. User profiling is the process of producing a profile of the user from historical information and past details. This research tries to identify the monitoring factors and suggests a novel observation solution to create high-performance sensors to generate the user security profile for a home user concerning the user's privacy. This observer agent helps to create a decision-making model that influences the user's decision following real-time threats or risky behaviours.

There are many recent propositions treating Model Driven Architecture (MDA) approaches to perform and automate code generation from design models. To the best of our knowledge and research, most of these propositions have been only focused on functional aspect by allowing code generation without considering this the non-functional aspect at the same time so that to generate secure object-oriented software basing on MDA approach. In this context, we are adding further details to integrate the security policies required in the form of secure models. The systems specification models will be enhanced with security requirements at different abstraction levels through a set of transformation models. Improving functional models with security constraints allow us to incorporate the security needs and automating generating secure applications with their security infrastructure using MDA approach. After carrying out a modification on MDA processes and UML meta-model to cover a better representation of security policies of an organization by updating different existing software engineering process to take into account nonfunctional aspect along with their functional aspect. This work presents a new methodology based on MDA approach and existing security technologies for allowing the integration of the proposed security requirements, which are obtained from security experts, during the system design. Within this context, we have focused on the essential elements of security, such as data encryption, Message Integrity, and Access Control in order to express the importance of merging both the functional and non-functional aspects altogether. We have chosen these properties to practically illustrate how to generate secure applications including their security policies. Then the source code will be obtained automatically from Platform Specific Models (PSM) by applying a set of model transformations and using a code generator designed for this mission. In addition, we can inject also other security-related properties, such as Availability, Traceability, non-repudiation, and Scalability issues during the whole development process by following the same methodology. these properties will be treated in the future work.
