Does ASL work with LiteSpeed?
Yes, ASL is supported with LiteSpeed.
Do the modsecurity rules work with Litespeed
When not used with ASL, or with ASL but not through the ASL Transparent WAF (T-WAF), please see this page for what rule language features Litespeed supports:
http://www.litespeedtech.com/support/wiki/doku.php?id=litespeed_wiki:mod_security_compatibility
Currently, if you do not use the T-WAF, 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.
When used with the ASL Transparent WAF (T-WAF) in ASL all rulesets will work.
