Wireless local area network (WLAN) has changed the paradigm of communication and become ubiquitous. As the number of devices connected on wireless is increasing, it is therefore, essential to find vulnerabilities in the security of wireless networks. In this research, WLAN security vulnerabilities are exposed in real time and digital forensics of WLAN for Windows and Android operating system-based clients are conducted. A real time wardriving was conducted in a residential area to emphasize the fact that WLAN broadcast sensitive information. The results of wardriving showed that 97% of WLAN access points (AP) were using WPA2. According to the data collected it was found that channel 11 and channel 1 were used by 52% WLAN APs and the average number of clients per AP was 1.59. Tenda WiFi wireless access point was set up with MAC filtering, hidden SSID and WPA2 security mechanisms in different combinations in such a way as to add an additional layer of security to previous configuration. The vulnerability assessment of security mechanisms of residential AP was performed with Kali Linux version 2017.1. A practical demonstration of exploiting MAC filtering, Hidden SSID with MAC filtering and WPA2-PSK with hidden SSID and MAC filtering security mechanisms of AP was carried out in real time. It was observed that the existing security mechanisms were vulnerable. Furthermore, the digital traces left behind or stored in 802.11 based devices were also explored in order to investigate wireless network attacks. Researchers have proposed probabilistic models for detecting MAC spoofing attacks of WLAN clients. However, in this research, a live forensic method based on changing position of legitimate client with respect to attack detector and observing received signal strength of wireless packets to detect MAC filtering bypass attack was proposed. De-authentication attacks on wireless networks were also detected. This thesis also explored the methods of finding WLAN artifacts from Windows and Android OS devices to determine whether a particular device was connected to an unauthorized wireless network or not. Researchers have exploited many security mechanisms of WLAN focusing upon a single parameter of WLAN security at a time. However, in this work, three available security mechanisms were cascaded to produce a three-layer security mechanism which was exploited in real-time.

قرآن حکیم میں متعدد مقامات پر وہ مستعمل ہیں مثلاً

" أَأَمِنتُمْ مَّن فِى ٱلسَّمَآءِ أَن يَخْسِفَ بِكُمُ ٱلأَرْضَ فَإِذَا هِىَ تَمُورُ " [[1]]

أدب الأطفال عند السيد أبي الحسن علي الندوي

Children's Literature” is defined as material written and produced for the information or entertainment of children and young adults. In simple terms, children’s literature comprises texts (novels, short stories, picture books, fairy tales, myths, poems) produced in various formats (print, digital, film, games) for children and young people. The first book for young people was printed in 1484 by William Cakistoon. Maulana Syed Abul Hasan Ali Nadvi was one of the greatest writer and Islamic thinker in the second half of the twentieth century. He wrote many books in Arabic and Urdu, and wrote more than fifty books. He also wrote for children and young adults. Famous of them are: Qasas un Nabiyeen, Searat Khaatam un Nabiyeen, Al Qiraat ur Rashida, Qasas min Altarikh Al Islami and min Alnjoom ilal Arz.

Esd Literacy-Based Model for Preservice Elementary Teachers: A Focus on Critical and Environmental Consciousness and Effective Teacher Development

The study investigated the status of ESD in teacher education of Pakistan; sustainability consciousness (an outcome of ESD) of the preservice teachers; and usefulness of ESD literacy-based pedagogical model with the preservice teachers.Such an investigation was undertaken in order to inform implementation of ESD in teacher education in Pakistan. Moreover, the study aimed at contributing towards knowledge on ESD pedagogies; ESD outcomes; and ESD-integration in university courses. The main focus of the study was on developing an ESD literacy-based pedagogical model and investigating its usefulness with the preservice teachers. Usefulness of the model was studied in terms of change in preservice teachers’ sustainability consciousness and their teaching practice as ESD pedagogues. Pedagogical model developed in the study was rooted in the transformative learning theory. To study the usefulness of the pedagogical model, action research was designed. The study employed a wide range of methods to gather data. To identify the status of ESD in teacher education in Pakistan, content analysis of the teacher education curriculum and policy documents was done in terms of ESD content, ESD processes and ESD learning. The documents included in the analysis were National Professional Standards for Teachers (NPST); National Standards for Accreditation of Teacher Education Programmes (NSATEP); and curriculum for B.Ed. (Honours) Elementary Programme.All these documents were prepared during the UN Decade of Education for Sustainable Development (2005-2014). Findings from the content analysis indicate that though some aspects of ESD-learning and ESD-processes have been included in the NPST and the NSATEP, there is no key standard on ESD in both documents. Similarly, in the B.Ed. (Honours) curriculum some courses have included ESD content and processes but there is no standalone course on ESD. Sustainability consciousness of the preservice teachers was investigated by adapting a survey tool developed by a group of xvii Canadian researchers (Michalos et al., 2015). Data were gathered from 207 students (preservice teachers) studying in the final year of the B.Ed. (Honours) Elementary Programme. Mean scores of the study respondents on the scale measuring sustainability consciousness were found significantly lower than the expected score. Moreover, they were significantly lower than that of upper secondary Swedish students. To study the usefulness of the pedagogical model (developed in the study), data were collected through pre-test, post-test, observation, participants’ written reflections and interviews. The findings showed that the pedagogical model i.e. Pedagogy of Sustainability Education in Teacher Education (PSETE) was useful in enhancing sustainability consciousness of the preservice teachers. However, it was only partially useful in transforming preservice teachers into ESD-pedagogues. ESD is a key field in the post-2015 development agenda, thus the findings of the current study may be used by Pakistan National Commission for UNESCO to help the concerned institutions to mainstream ESD in teacher education because mere addition or integration of ESD in some of the courses is not enough to transform preservice teachers as ESD pedagogues. Study findings may be used by the teacher educators to integrate ESD in their courses.
