Does ASL work with LiteSpeed?

Yes, ASL is supported with LiteSpeed.

Do the modsecurity rules work with Litespeed

When used with ASL all rules work.

Please see this page for what rule types Litespeed support:

Currently, if you do not use ASL, this means Litespeed does not support the following features:

Output analysis: This means Litespeed can not inspect the output from the web server. This means rules like malware detection, malicious shell prevention, brute force protection, data loss protection and other rules that analyze the output from the web server are not supported by Litespeed, unless you use ASL.
XML inspection: Litespeed has chosen to not support XML inspection, this means XML based attacks are unfortunately not protected on that platform, unless you use ASL.
Multi-part Upload protection: Litspeed does not support scanning attached files content in multi-part upload. If you use ASL you will be able to scan attached files in a multi-part upload.
lua: This is a language that lets us construct advanced rules. Currently they are used for advanced anti-spam protection and advanced SQLi and XSS injection protection. Therefore, these types of rules are not supported by Litespeed, unless you use ASL.

Step 1) Log into ASL.

Step 2) Click on the "Configuration" tab.

Step 3) Click on the "WAF" tab and select "WAF configuration".

Step 4) Click the "Add" button.

Step 5) Select "Local Web Server" from the "Add protection for" drop down.

Step 6) Select the port that litespeed runs on. Normally this is port 80.

Step 7) Check the SSL box

Enter the file system path to your SSL certificate, and SSL key in the "Path to SSL Certificate" and "Path to SSL Key file" boxes.

Step 8) Click Save

Note: Litespeed does not support the WAF in embedded mode.
