It is mainly designed to serve dynamic and small team sizes, who are usually collocated in one place. These features make agile methodologies suitable to be applied in managing small and medium-sized enterprises (SMEs), where the number of their members is limited, and the nature of their projects is usually dynamic and flexible. This research tries to study the current state of SMEs' project management in Saudi Arabia and to what extent they are applying agile methodologies. A survey of twenty-six enterprises with different sizes reveals that most of the SMEs are following the core concepts of agile methodology, despite that more than half of them are not aware of the agile concept and its best practices. This result leads that agile methodologies are suitable to be applied to SMEs in Saudi Arabia. However, there is a need to spread awareness and deliver solutions to these enterprises that help them in adapting the best available agile practices and tools. Moreover, following these well-known practices would help to raise productivity and efficiency of their work.","PeriodicalId":305464,"journal":{"name":"2018 21st Saudi Computer Society National Computer Conference (NCC)","volume":"71 3-4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133786052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The UWSNs face many challenges such as noise, high transmission delays, high deployment cost, movement of nodes, energy constraints, etc. In UWSNs nodes are sparsely and unevenly deployed, that may results in void hole occurrence. Secondly low propagation speed in UWSNs causes high end-to-end delay and energy consumption. In this paper, we propose two schemes: Adaptive Transmission Range in WDFAD-DBR (ATR-WDFAD-DBR) and Cluster Based WDFAD-DBR (CBWDFAD-DBR). In aforesaid scheme to reduce the probability of void hole this scheme adjusts its transmission range when it finds a void node and then continues to forward data towards the sink. In later, to minimize end-to-end delay and energy consumption network is divided into clusters. Simulation results show that our schemes outperform compared with baseline solution in terms of average Packet Delivery Ration (PDR), average energy tax, end-to-end delay and Accumulated Propagation Distance (APD).","PeriodicalId":305464,"journal":{"name":"2018 21st Saudi Computer Society National Computer Conference (NCC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116186660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Basically clustering means grouping some specific objects based on their behavior and functionality. Clustering can be formulated for different optimization problems, such as nonsmooth, nonconvex problems. This paper is based on the review of the optimization algorithm that was proposed in the paper A Convergent Incremental Gradient Method With Constant Step Size by Blatt et al called Incremental Aggregate Gradient method. A novel algorithm called Incremental Clustered Aggregate Gradient Method was proposed in this paper to counter the shortcomings of the previous one. It has many similarities with the earlier method but it is more efficient for wireless sensor networks. The main aim of Incremental Gradient Method was to minimize the sum of continuously differentiable functions and also it required a single gradient evaluation per iteration and used a constant step size. For quadratic functions, a global linear rate of convergence was proved. It was claimed that it is more suitable for sensor networks. Although the experiments performed in this work confirm the convergence properties of it, it was found that it is not suitable for sensor networks. The proposed method addresses the flaws of the previous method as regards to sensor networks. When both algorithms operate with their respective optimal step sizes, they require approximately the same number of gradient evaluations for convergence.","PeriodicalId":305464,"journal":{"name":"2018 21st Saudi Computer Society National Computer Conference (NCC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124906100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

APTs ignited a fire of information warfare where they form cyber-attacks with a high-risk for very critical and secured infrastructures. They targeted a specific companies and governments. The most significant feature of APTs is their ability for bypass high-profile of security systems and steal or tamper information for doing negative impacts on physical objects. Stuxnet virus is an example of APTs that has a specific target and has an ability to destroy its physical infrastructures. It did not need Internet for spreading. It revealed in 2010 and targeted Iran’s nuclear program by exploiting four zero-day vulnerabilities in Windows Operating System. In the recent years, a number of different APTs have emerged which increased researchers’ attention to analyze them in order to find solutions to protect against existing and future APTs. In this paper, we examine the majority of existing reports and research papers of Stuxnet and APTs to give an overview of characteristics, features, and operations of each of them. We cover Duqu, Flame, Shamoon and Triton as recent variances of Stuxnet. In addition, we highlight the differences and similarities between Stuxnet and these APTs to help in predicting future attacks and encourage the researchers to find solutions to protect against them.","PeriodicalId":305464,"journal":{"name":"2018 21st Saudi Computer Society National Computer Conference (NCC)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126788537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a wide array of PDTs that a common person uses frequently including Automated Teller Machines (ATM), interactive kiosks, self-service kiosks and so on to accomplish numerous day-to-day tasks. Improving the usability of PDTs has been targeted from various aspects by Human Computer Interaction researchers. Research in this area has spanned from using multimodal approaches, revised guidelines for kiosk construction, navigation restructuring, to alternative methods of user authentication to provide an improved and enhanced user-experience. The main issue with the solutions provided to this day is that they all target improving the device. Providing a personalized solution remains unanswered. The widespread use of smartphones and tablets has given rise to the next generation of e-commerce commonly known as m-commerce. Although m-commerce have made huge strides in the areas of mobile payments, the area of making use of mobile technology with public access terminals is still limited. As technology edges towards cardless and contactless transactions, we propose to provide an accessible and scalable solution to the use of PDTs using proximity-aware technology. The main objective of the work presented in this paper is to identify and discuss the feasibility of using proximity-aware solutions to address the security, privacy and accessibility concerns when using PDTs.","PeriodicalId":305464,"journal":{"name":"2018 21st Saudi Computer Society National Computer Conference (NCC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124995576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among different hacking methods which they have, they preferred to begin with web application. It allows them to deal the most damage for the least effort. This paper present the analysis of methods of hacking web application, which hackers used in attacking most of the systems. Hackers usually performs these attacks by looking into the web overall, its architectures, and the related security risks. In addition, it discusses recent scenarios happening with perspective of the Kingdom of Saudi Arabia. As we know, hacking on Equifax website exposes data for 143 million US consumers. While focusing on Saudi market, there are 40% of companies that have been affected by internal information security incidents.
