Firewall : this is the software to stop a hacker gaining access to a machine or server.For linux a good FREE firewall is GUFW firewall.
To install it use:
sudo apt-get install gufw
GUFW has 3 profiles : home , office , public. Home is the default and denies ALL incoming and allows all outgoing traffic.
ALLOW option : will allow ALL traffic.
DENY: will quietly discard packets.
REJECT: Will send a reject packet to the sender.
RULES: These allow you to selectively Allow/Deny specific ports.
Use the REPORT tab to see which applications are using which ports.
A Rootkit allows a hacker to gain Root access by using malicious software. To check for these use a Root kit checker such as chkrootkit.
To install use: sudo apt-get install chkrootkit
It scans for ROOTKITS and MALWARE.
To use: sudo chkrootkit
