On file systems that support it you can set the immutable bit (weak). On file systems that do not support extended attributes you could mount another /root directory over it with the ro flag set (even weaker option).

*Do note anyone with root privileges can undo things. Also note immutable files are of no use if the real cause of the problem should not be addressed through the use of technology (as in PEBCAK).
how about scrub command? is it possible to set it to files i need to prevent any changes by other ?

cf-know(8)						      System Manager's Manual							cf-know(8)

NAME
cf-know - cfengine's knowledge agent SYNOPSIS
: cf-know [options] DESCRIPTION
: The knowledge management agent is capable of building and analysing a semantic knowledge network. It can configure a relational database to contain an ISO standard topic map and permit regular-expression based searching of the map. Analysis of the semantic network can be per- formed providing graphical output of the data, and cf-know can assemble and converge the reference manual for the current version of the Cfengine software. cfengine is a self-healing configuration and change management based system. You can think of cfengine as a very high level language, much higher level than Perl or shell. Asingle statement is called a promise, and compliance can result in many hundreds of filesbeing created, or the permissions of many hundreds offiles being set. The idea of cfengine is to create a one or more sets of configu- ration files which willclassify and describe the setup of every host in a network. COMMAND LINE OPTIONS
