Default Level

2: Configuration level

Usage Guidelines

No default operating system is specified in the IPS signature filter.

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.

Example

# Configure operating system unix in IPS signature filter hello in intrusion prevention profile profile1.

<sysname> system-view
[sysname] profile type ips name profile1
[sysname-profile-ips-profile1] signature-set name hello
[sysname-profile-ips-profile1-sigset-hello] os unix-like
