This study develops a security indicator prioritization framework based on multi-source log correlation on the JDIH Kota Padang website. A descriptive quantitative method was applied using access logs, authentication logs, and error logs. The analysis involved parsing, event categorization, percentage calculation, visualization, and Security Event Priority Score (SEPS). The results identified 213,356 requests, 20,630 unique IP addresses, 24,315 responses with 404 status, 14,222 responses with 403 status, 80,525 failed password events, 61,393 invalid user events, and dominant directory forbidden and file not found errors. The SEPS framework supports administrators in determining security monitoring priorities.
