To block such malicious websites, various organizations and individuals, e.g., security vendors, analyze URLs and create blocklists. Some blocklists are paid and some are free public blocklists; however, the effectiveness of public blocklists is generally not guaranteed. Thus, many studies have attempted to verify their effectiveness. To the best of our knowledge, public blocklist providers (PBP) have not been studied as rigorously as blocklists, and it is still unclear how blocklists should be operated and how PBP websites should be designed to maintain the effectiveness. Therefore, to unveil more characteristics of the PBP, we designed a measurement study to analyze PBPs in terms of lifespan, update frequency, entry bias, and user interface metrics. In this paper, we describe the results of measuring seven PBPs according to these four metrics.Metrics/Measurement | Network monitoring | Security and Protection | Services Operation | User Interfaces | Web-based servicesconference paper10.1109/ISCC55528.2022.99130092-s2.0-85141168205https://api.elsevier.com/content/abstract/scopus_id/85141168205
