Threat of information security has impact to business of organization. Therefore, the development of information security risk model should consider business perspective. In order to develop new risk model, defining metrics is important process. It can be conducted by theoretical analysis, validity analysis and reliability analysis. Theoretical analysis and validity analysis had been performed in previous work. Furthermore, reliability analysis is performed in this paper. Cronbach's Alpha is required as method to measure reliability coefficient from five proposed metrics namely reputation, financial impact, critical level, business type of organization, and size of organization. Reliability analysis from proposed metrics results coefficient between 0.70-0.91. Based on previous researches, metric is reliable if it has coefficient greater than 0.65. Therefore, proposed metrics have adequate reliability to be used as metrics of risk model.

Layanan dan infrastruktur telekomunikasi merupakan bagian penting dari kehidupan modern karena hampir di segala bidang membutuhkan hal tersebut seperti pendidikan, pemerintahan, ekonomi dan sebagainya. Oleh karena pentingnya sektor telekomunikasi di Indonesia sebagai negara kepulauan maka perlu evaluasi tentang penyebaran layanan dan infrastrukturnya selain dilihat dari sisi fungsional dan perkembangan teknologinya. Provinsi Papua adalah provinsi terbesar di Indonesia namun justru memiliki layanan telekomunikasi yang paling sedikit dan terbatas. Demikian pula untuk penyebaran layanan ke kabupaten maupun ke distrik (kecamatan) masih belum merata. Hal tersebut terbukti dari laporan hasil distribusi pita frekuensi yang hanya 1,5% untuk kawasan Maluku dan Papua serta kerapatan layanan tiap kabupaten yang ditunjukkan pada hasil penelitian ini.

Involvement of digital information in almost of enterprise sectors makes information having value that must be protected from information leakage. In order to obtain proper method for protecting sensitive information, enterprise must perform risk analysis of threat. However, enterprises often get limitation in measuring risk related information security threat. Therefore, this paper has goal to give approach for estimating risk by using information value. Techniques for measuring information value in this paper are text mining and Jaccard method. Text mining is used to recognize information pattern based on three classes namely high business impact, medium business impact and low business impact. Furthermore, information is given weight by Jaccard method. The weight represents risk levelof information leakage in enterprise quantitatively. Result of comparative analysis with existing method show that proposed method results more detailed output in estimating risk of information security threat.
