CENTOS 7 Auto Hardening

You will need to build set of files, by the specification I will provide you, in order to make automatic hardening of CentOs 7.

The specification contains less than 300 parameters total, like the example:


1. Securing xinetd /etc/xinetd.d Disabled

1.1.2. Install TCP Wrappers Disabled

1.1.3. Network Services Banners Disabled

1.1.4. Network Services Access Control (xinetd) Disabled

2.2.1 Network Parameters Modification net.ipv4.tcp_max_syn_backlog 4096 net.ipv4.tep_syncookies 1 netipv4.conf.all.cp_filter 1 net.ipv4.conf.all.accept_source route 0

2.4.3. Files and Directories Permissions /etc/passwd Owner: root; Group: root /etc/group Owner: root; Group: root /etc/shadow Owner: root; Group: root

2.6.1 Account and Password Settings No legeey + entries in passwd, shadow, and group files Remove all entries of “+:” from the files passwd, shadow, and group files Block System Accounts Lock all accounts (except root) with uid less than 500 and set /sbin/nologin as the login shell No accounts with empty password fields Assign passwords to user accounts

2.7.2. Authentication ChallengeResponseAuthentication should be set to No # SSH setting: ChallengeResponseAuthentication No GSSAPIAuthentication should be set to no unless GSSAPI authentication is required. This is used for direct Kerberos authentication # SSH setting: GSSAPtIAuthentication no GSSAPICleanupCredentials should be set to the default value yes. This setting deletes Kerberos credentials when the user logs out # SSH setting: GSSAPICleanupCredentials yes

Please make sure you know how to provide automated hardening files for the examples I have provided, before making any bid.
