Operating System, Application and Network Hardening Resources

Information Technology is becoming more challenging these days, hence IT Security is a key area when it comes to Operating Systems, Applications and Networking.

The process of securing an operating system is referred to as “hardening” or at times as “lock down” It is important to an organization’s security because it reduces the chances of attack. Issues come up because various operating systems require different hardening processes within a data center. For example, a system administrator may have deep expertise in one operating system but may possess limited or even no expertise with the other operating systems. System administrators also have a task of ensuring that each server remains locked down consistently to avoid vulnerabilities.

Most of the IT Administrators will have difficulties finding the properly defined set of Hardening guides. To overcome the such issues, Center for Internet Security (CIS) has published well defined and detailed hardening guides to the public (FREE). 


With the above repository, you will get the change to download all the hardening guides on Windows OS, Mac OS, Linux OS, Applications, Network devices & etc.

For the ease of access, i have attached two common hardening guides as below;

SFTP vs. FTPS : Which One To Use?

SFTP Overview

SFTP (SSH File Transfer Protocol) is referred to as the extension of the SSH protocol which permits the transfer of files through a network.

FTPS Overview

FTPS is a protocol that utilizes a Secure Sockets Layer (SSL) certificate to provide security. The authentication of a protected FTP connection is conducted through the use of the following elements: SSL certificate, user ID, and password. Upon creation of an FTPS connection, the destination FTP server is reviewed through the FTP client software to verify the trust-ability of a server’s certificate.

Difference between SFTP and FTPS

SFTP vs. FTPS : Which One To Use?

Each user has unique requirements when it comes to selecting the most appropriate transfer protocol. However, using FTPS is recommended if a server requires accessibility from portable devices, such as PDAs and smartphones or operating systems which do not have SFTP/SSH clients and yet provide FTP support. Accordingly, SFTP is the way to go if you are seeking to develop a custom security solution.

As for the client side, the requirements are already determined by the server(s) with which they intend to connect. SFTP is the more favored choice when establishing a connection with internet servers due to the by-default support that it enjoys from UNIX and Linux servers.

On the other hand, you have free rein to choose both FTPS and SFTP in case of private host-to-host transfers. However, you would have to hunt for a free FTPS client and server software to use FTPS or buy a license for commercial usage.
