Hi Dan,

rule 100109 is the rule to raise the severity for certain files .

For example (I haven't got my configuration available right now but it
looks like this):

<rule id="100109" level="10">
   <if_sid>550</if_sid>
   <match>for: '/etc/hosts|for: '/etc/services</match>
   <description>Important Unix file changed</description>
</rule>


Thank you
