Introduction
In the last article, we described a list of checks which can determine if a system is compromised or hacked. In this article, we will talk about preventive steps (especially infra-related) that can be taken care of to avoid hacking or to make the system more secure. There are many directions in which we can secure our application as follows:
- OS Hardening (Infra Level Security).
- Secure Coding Guidelines.
- Encryption Of Sensitive Data.
- Ensure No Vulnerability Exists in System.
In this blog, we will be concerned about OS hardening (Infra Level Security) in Linux systems (CentOS/Redhat). We will cover other parts in future blogs.
