Regras recomendadas para Mod Security

Olá amigos, tudo bom?

Gostaria de saber se existem regras padrão para o Mod Security.

Como os usuários mais experientes do fórum devem ter percebido, sou novo como "root" e tenho me dedicado bastante a aprender a gerenciar e tornar meu servidor mais seguro.

Tentei incluir isso aqui:

 

<IfModule mod_security.c>

    # Only inspect dynamic requests
    # (YOU MUST TEST TO MAKE SURE IT WORKS AS EXPECTED)
    SecFilterEngine DynamicOnly

    # Reject requests with status 403
    SecFilterDefaultAction "deny,log,status:403"

    # Some sane defaults
    SecFilterScanPOST On
    SecFilterCheckURLEncoding On
    SecFilterCheckCookieFormat On
    SecFilterCheckUnicodeEncoding Off

    # Accept almost all byte values
    SecFilterForceByteRange 1 255

    # Server masking is optional
      SecServerSignature "GNU Microsoft-IIS/0.9Beta"

    SecUploadDir /tmp
    SecUploadKeepFiles Off

    # Only record the interesting stuff
    SecAuditEngine RelevantOnly
    SecAuditLog logs/audit_log

    # You normally won't need debug logging
    SecFilterDebugLevel 0
    SecFilterDebugLog logs/modsec_debug_log

    # Only accept request encodings we know how to handle
    # we exclude GET requests from this because some (automated)
    # clients supply "text/html" as Content-Type
    SecFilterSelective REQUEST_METHOD "!^GET$" chain
    SecFilterSelective HTTP_Content-Type "!(^$|^application/x-www-form-urlencoded$|^multipart/form-data)"

    # Require Content-Length to be provided with
    # every POST request
    SecFilterSelective REQUEST_METHOD "^POST$" chain
    SecFilterSelective HTTP_Content-Length "^$"

    # Don't accept transfer encodings we know we don't handle
    # (and you don't need it anyway)
    SecFilterSelective HTTP_Transfer-Encoding "!^$"

</IfModule>

Peguei neste site aqui.

Mas ficou dando erro.

Alguma sugestão?
