Hello people,
So, long story short, I have been messing around a little bit trying to
remove unnecessary stuff in my GNU/Linux system, especially services that are
able to connect/listen on internet ports.
So far I have removed:
OpenSSH - Never access my computer remotely, so why have a program running
that might be used to attack my system and NEVER be used myself?
FTP - Again, I never use FTP server in my home. Maybe I will do it one day,
and if so I will reinstall it through reps, but I am sure my laptop doesn't
need FTP services to be running in the background.
Avahi - This would be cool if I was using other computers in home network, or
wanted to use for example a wireless printer, but as it is, I have no use for
this.
Telnet - I am probably just ignorant here, but why would I want to have a
program that allows remote access without the decency of encryption?
So far I have removed these. I would like to ask what other services are not
needed in a laptop that is not part of any complex network, only use it to
connect to the internet and my phone (through the wifi at home, phone
creating the ftpserver itself), AND might be used to connect to the internet?
If I am not using it, it doesn't belong in my computer, and it shouldn't be
there waiting for someone to bypass my firewall, and use an exploit in that
program to own my system.
Any help, much appreciated :)
Thanks in advance!
