2.  Outdated third party applications: this includes outdated software such as Apache, PHP, MySQL, OpenSSL, and VNC

3.  General lack of patch management for the OS

5.  Lack of backups

Ways to hardened the Linux/Unix based computer system is do the following:

1.  Perform minimal Installation: this involves, installing softwares that are necessary, and limiting the number of admin users on the computer system.

2.  Carry out Code Auditing: this is a means of preventing security issues, by withing more secure softwares to prevent variable declarations, or otherwise unexpected logic.

3.  Ensure there is a Traffic filter firewall: this will helps to attacks from external users or hackers. Install, Web Applicatio firewall, which helps to filter out traffic.

4.  Carry out Softwares updates: a software update can help prevent or guide against security leaks in a software

5.  Install security updates only: this is done by filtering out the security-related programs and only upgrade packages which are referred to in the custom file.
