You can configure this command if the detected attack targets at an operating system.
other indicates the operating systems other than android, ios, unix-like, and windows. Therefore, running the os command with parameters android, ios, unix-like, windows, and other being specified is the same as the default setting.
A user-defined signature applies to all operating systems by default. The applicable operating systems cannot be manually configured.
