You can get firewall log files from any Cisco ASA devices (the 5500 series: 5505, 5510, 5520, 5540, 5550 5580 models and 5500-X series: 5506-X, 5508-X, 5512-X, 5515-X, 5516-X, 5525-X, 5545-X, 5555-X, 5585-X models, and Cisco Adaptive Security Virtual Appliance (ASAv)) by using an external Syslog server.
