When i try to run "chcon ––unconfined_u:object_r:etc_t:s0 index.html" i get "chcon: failed to change context of ‘index.html’ to ‘\302\226\302\226unconfined_u:object_r:etc_t:s0’: Invalid argument" error

[@TechArkit]

chcon is no more in RHEL 7. Use semanage

[@zymagoras]

@@TechArkit I was able to do it using "chcon -t etc_t index.html"

[@TechArkit]

@@zymagoras always use semanage and restorecon is a good practice in RHEL 7 and 8 versions

[@asdaqamin]

Its good Demo of SELinux. is there a real use in Production level. I still not find any reason where to use it.

[@TechArkit]

You can use SELinux in all production devices where Linux is installed, the only problem here is SELinux do not have context rules for all applications Example: Nagios Monitoring Tool.

[@vamsikrishnakolla6060]

in real time selinux is in which mode ?
it's in enforcing or permissive or what

[@TechArkit]

it depends on security standards what company is using. Most of the time permissive. since SELinux is not compatible with all applications.
