I'm using Apache on a Raspberry. The used version is the one I get with apt-get upgrade.
| Code: | Server version: Apache/2.4.25 (Raspbian)
Server built: 2019-10-13T15:43:54 |
Since this is a "sensitive" server exposed to the internet, I want to - among many other security measures - completely hide the servers signature. I use:
| Code: | <IfModule security2_module>
SecRuleEngine on
ServerTokens Full
SecServerSignature "Go Away!"
</IfModule> |
But the response still is "Go Away! mod_fcgid/2.3.9".
How do I hide the string "mod_fcgid/2.3.9"?
[Update]
I was too fast with asking  Found an solution myself. Just set "ServerTokens OS".
[Update 2]
It seems that Major|Minor|Min[imal]|Prod[uctOnly]|OS work (Full does not) as long as the SecServerSignature string is not longer than the one set by ServerTokens . So "GoAway" works with "Prod" (writes "Apache") since both strings are 6 chars long.
If the post is of no use for others, just delete it... |

Another option is to use mod_bikeshed[1]
You can change the signature completely. However security through obscurity is not the best option

In addition to what James Blond mentioned about using mod_bikeshed (which I use as well to hide all APACHE info to the world), you should also hide all PHP info to the world. To hide PHP from the world, make the following change in your PHP.ini file:
Change the following option
expose_php On
to
expose_php Off |

GLS ... That is true. I just generally do not like to give the evil doers in this world too much to work with, so I do my best to hide as much from them as I possibly can.
Just my 2cents worth  |
