Product Name: LES ( Linux Environment Security )
Product Version: 0.2 Rev.1
Homepage: http://www.rfxn.com/projects/linux-environment-security/
Description: Linux Environment Security is intended as a facility to quickly & easily secure RedHat/RPM based environments (i.e: turbo linux, open linux). It does such by enforcing root-only permissions on system binaries (binaries that have no place being
executed by normal users), enforcing root-only path traversal on system paths, enforcing immutable bit on essential rpm package contents (i.e: coreutils), and enforcing immutable bit on shell profile scripts.


Step 1: Downloading, Installing LES

cd /usr/local/src
wget http://www.r-fx.ca/downloads/les-current.tar.gz
tar -zxvf les-current.tar.gz

/usr/local/sbin/les -ea

Options:
-da | --disable-all Disable all options
-ea | --enable-all Enable all options
-sb | --secure-bin Set root only execution of critical binaries
-sp | --secure-path Set root only traversal of critical paths
-sr | --secure-rpmpkg Set immutable on core rpm package binaries
-so | --secure-prof Set immutable on interactive login profiles
-sd | --secure-devel Set access to devel utils for group deva & root
