Abstract Network security is becoming more crucial as the volume of data being exchanged on the internet. A more practical way to protect information is to alter it so that only an authorized receiver can understand it. Security of data and telecommunication can be done by a technique called cryptography. In this thesis Data Encryption Standard algorithm has been improved. Improved algorithm uses input data 512bit and key of 256bit length to encrypt the data. It uses S-boxes similar to those...
Abstract Project Based Learning (PBL) is about giving students a real projects and asking them to come up with solutions to it as an academic task. Studies pointed out some problems associated to PBL approach, such as social loafing, that is when some students hide themselves behind active students, doing less or no works within the team and put the effort on other team members. Another problem is unfair assessment which result in giving all the students the same marks in spite of their effor...
Abstract Text mining is an important field in information retrieval; it organize a large number of text documents that available on the internet to facilitate the retrieved processing and increase efficiency. Text classification is automatically determining the category to new or unseen documents that depends on content of document itself. In text classification, text preprocessing is a fundamental step to obtained a better result. The Arabic text processing depends on stemming algorithms to ...

Digital crimes have increased in number and sophistication affecting the networks quality of services parameters like confidentiality, integrity and availability of resources. Network Intrusion Detection Systems (NIDS) are deployed to optimize detection and provide comprehensive view of intrusion activities. However, NIDSs generates large volumes of alerts mixed with false positives, and repeated warnings for the same attack, or alert notifications from erroneous activity. This prevents ...
Investigation of social media using social network theory is a new powerful tool that will aid and ease law enforcement agencies in multi-faceted ways in this ever evolving digital landscape.

The traditional techniques used by forensic investigators through the incident response operations include mostly pulling out the power cable of the suspected machines. This method normally causes a major interference of the evidence gathering process, hence the need for a better investigation method. The purpose of the study was to provide a means for the Kenya Police in evaluating their forensic adoptability in digital forensic evidence. This study was intended for those who were opera...
The need by staff and students to use smart mobile devices in university network is indisputable. This is because they help them to work and study more effectively as well as achieve better work-life balance. However smart mobile devices pose a security challenge as they continue toexpand the corporate network unchecked thus increasing the attack surface. This creates a major security burden to security professionals who are supposed to ensure that smart mobile devices’ adherence to t...
Personal Identification Systems are implemented to assist in identifying, authenticating and authorizing the right persons to the right entitlements. Criminals have however discovered ways of by-passing them in order to perpetrate identity fraud. As a result, the problem of identity fraud has become one of the fastest growing crimes in the world today, and a key facilitator of terrorism, money laundering and trafficking (of people, drugs, weapons and illicit material). In this study, an ...
Road traffic accidents have been a major cause of deaths in Kenya. The effort by Kenya police to enforce traffic laws has done little to salvage the situation. Although there has been other remedies towards curbing road accidents such as; improvements in vehicle design and licensing to skill the situation calls for further solution particularly targeting driver behavior since careless driving has been identified as a major cause of road accidents.
