I need help answering the question below.

1.Discuss the need to secure unused applications and ports for the purposes of hardening your server? As a Linux System Admin, talk about the importance identifying open access points and why these ports are potentially a liability? Give at least three examples and support your statements with facts.

2.Discuss the roles of the xinted “super deamon” and TCP Wrapper in securing access to your systems? As a Linux System admin, talk about how these can be used to further harden your system and the importance of how you apply these tools? Give examples and support your answers.
