The instruments was used in this research was expanding dynamometer, which is aimed to measure the strength og arm and shoulder muscles. After that, the data was analysis by using statistic to examine the normality with liliefors test on the significant level 0,05a. The subritted hypothesis was there is the effect of Barbell Pullover exercise toward strength of arm and shoulder muscles. Based on the data analysis t test showed T count was 21,95 and T table was 1,812, it means that T count > T table. Based on the statistic data analysis, the average of preetest was 12,1 and the average of posttest 15,7 was it. Shows that the data was normal. In conclution , there was the effect of Barbell Pullover exercise toward strength of arm and shoulder of smpn 6 pekanbaru man vollyball club

Towards an enhancement of organizational information security through Threat Factor Profiling (TFP) model

Information security has been identified by organizations as part of internal operations that need to be well implemented and protected. This is because each day the organizations face a high probability of increase of threats to their networks and services that will lead to information security issues. Thus, effective information security management is required in order to protect their information assets. Threat profiling is a method that can be used by an organization to address the security challenges. Threat profiling allows analysts to understand and organize intelligent information related to threat groups. This paper presents a comparative analysis that was conducted to study the existing threat profiling models. It was found that existing threat models were constructed based on specific objectives, thus each model is limited to only certain components or factors such as assets, threat sources, countermeasures, threat agents, threat outcomes and threat actors. It is suggested that threat profiling can be improved by the combination of components found in each existing threat profiling model/framework. The proposed model can be used by an organization in executing a proactive approach to incident management

Scoring matrix framework for threat factor profiling model

One of the important requirements in preparing for an information security risk management system is to construct a threat profiling model that can be used to identify and classify threats. The threat profiling model provides an organization with a complete set of information including pattern of threat scenarios and analysis on the threat they encounter. However, an organization must set objectives and results of a threat profiling, as well as metrics in order to measure, appreciate and counter the potential threats. The main contribution of this paper is the framework of the threat scoring which extends our previous findings on combinations of components found in referred threat models. Furthermore, to the best of our knowledge, threat scoring framework has not been investigated by any previous approaches. In fact, the computed threat score enables the quantification of the degree of threat severity which is an important benchmark for an organization to plan their countermeasure actions. Therefore, a scoring matrix framework for Threat Factor Profiling (TFP) model that includes identification and classification of threat is proposed. The purpose of this framework is to identify threats based on activity within an information system of an organization. The Threat Profile Report presents the collected data of threat based on the predetermined matrix
