(.*) means "any character, 0 or more times".
"0 times" here means that it matches an empty string. (Technically, it
is an empty string, not null).
URL for the home page is "/".
(The first line of an HTTP 1.x request will be "GET / HTTP/1.1".
By definition of the protocol, there has to be some text between the
verb (GET) and the version.)
A possible solution that I see is to make the first '/' explicit.
adding it both to the regexp and to the replacement string:
RewriteRule ^/(.*)/+$ https://linuxsecurity.com/$1 [R=301,L]
Alternatively, use '+' instead of '*' (meaning 1 or more times):
RewriteRule ^(.+)/+$ https://linuxsecurity.com$1 [R=301,L]
