The information systems audit is an proactive action to find out the predicted issues on proceeding the business beforehand, to make out whether the information systems satisfies the user's demand or not and to check up the result of the project with complementing the capabilities of self-diagnostics for the complicated and advanced information system. However, the results of the audited project are apt to be regarded as a failure in a case that an opinion of the audit area evaluation is described as 'insufficient' or 'negative' in the audit report that is submitted as the result of the audit. It makes a lot of arguments among the board of audit, the institution ordering the audit and the auditor. In this study, we made an attempt to finding out the factors affecting the audit area evaluation and verifying them objectively. A study model and hypothesis including the improvement type of the recommended subject to be improved, the importance, the audit time, the business scale of the audited object and the auditing company as a factor variable were established and the hypothesis was verified by analyzing the correlation between the factor variables and the audit area evaluation.

Many researchers have proved that information systems auditing is a very effective tool for improving information systems quality. However, information system auditing in Korea still includes many subjective judgements. This study deals with applying a quantitative model to improve information system auditing quality on security domain. First of all, we have looked at previous researches on information systems audit, especially on security audit. Based on this survey, we have come up with solutions to improve the evaluation efficiency on security audit. We have merged the security audit guidelines of NCA and KISA, and developed a quantified evaluation scheme. We have proved the validity of this model by interviews with experts and by case studies.

지금까지 정보시스템 감리는 감리수행자 관점에서 이루어져왔다. 그리고 감리의 주된 초점은 에러나 잘못된 기능을 찾기 위한 관리적이고 통제적인 입장에 맞춰져 있었다. 그러나 감리의 최종 목적은 보다 나은 정보 서비스를 통해 조직을 장기적으로 강하게 만들기 위한 의사결정을 내리는데 도움을 주기 위함이다. 따라서 본 연구에서는 조직의 경쟁력을 높이기 위해 도움이 되도록 감리의 기존 개념을 확장하였다. 이러한 목적을 달성하기 위해, 정보시스템 감리에도 '서비스' 개념을 적용하였다. 첫째, 정보시스템 감리를 위해 서비스 개념이 반영된 6개 항목 24개 지표를 도출하였다. 둘째, 감리 관련자들을 세 그룹으로 분리하였다. 세 그룹으로 나눈 이유는 각 그룹별로 서로 다른 차이점 이 있기 때문이다. 셋째, AHP기법을 이용하여 6개 항목 24개 지표들에 대해 각 그룹별 가중치를 정량화 하였다. 이러한 결과는 각 그룹별로 항목들의 중요도를 어떻게 생각하는지 분명히 보여주었다.

The auditor, an important instrument of corporate governance, ensures the transparency and accountability of the firm to the stakeholders. The objective of this paper is to explore the impact of audit characteristics on firm performance. In this study, external audit quality (BIG4), frequencies of audit committee meetings, and audit committee size are used as the proxies of audit characteristics and firm performance is measured through ROA, profit margin and EPS. A total of 503 firm years are considered as sample size from the listed manufacturing firms of Dhaka Stock Exchange (DSE) during the period of 2013 to 2017 to find out the impact of audit characteristics on firm performance. In this study, multivariate regression analysis is conducted using the pooled OLS method. Moreover, time dummy and lag model of multivariate analysis are also analyzed as robust check. The multivariate regression results find that external audit quality (BIG4) and audit committee size are significantly positively associated with firm performance. This study also finds that there is a significant negative relationship between audit committee meeting and firm performance. This study recommends that the regulatory authority and audit committee should review the frequencies of audit committee meeting to make it more effective to ensure better firm performance.
