The program that handles your Web pages on the "back end" is called a Web server. Scalability, security and speed are all impacted by the Web server. Like the way your computer stores files on its hard drive, the Web server stores files which makes up a website.
Server configuration is critical to protect your website from third-party tampering. It is vital that your Web server supports security protocols like Secure Socket Layer (SSL) which encrypts messages. Through SSL, any sensitive transaction which was made from your Web server is translated into a secret code which is difficult to crack.Other Security protocols are Secure Hypertext Transfer Protocol (SHTTP), Private Communication Technology (PCT) and Internet Protocol Security.
Creating a back up is tedious work and for this reason it is often neglected. This can produce disastrous results. It is essential to back up your Web server before implementing upgrades or configuration changes. If an unanticipated problem occurs, backing up will restore your server into a known configuration without losing vital information.
The foundation of any server security is proper patch management. Insecure web applications can be accessed by a local exploit. If an intrusion hacker can compromise a web application he’ll run an exploit script which could grant him a root access on your system, then any local exploits are now at their disposal.
