In this faced business world, organizations across the globe are progressively moving towards adopting technology-driven solutions to optimize their performance. In this light, server virtualization enables all size businesses to trim-down their IT-related costs while appropriately managing their infrastructure to avoid a single point of failure.

Linux Dedicated Server is an open source software, which supports various scripting languages like C, C++, PHP or Perl. The server provides a complete flexibility to businesses to have a complete control over their server. It further facilitates them to manage and run their operations from any location by just having an Internet connection on their PC/laptop. 

However, the reliability and complexity of these servers make them highly prone to virtual and visible security threats against data/information. 

Let's take a quick glance at how service providers are visualizing comprehensive server security to safeguard their web servers against any potential threats

The main objective behind the security of Linux server is to create a single or multiple layer protection wall against various security breaches. 

The host of measures followed by a hosting service provider includes:

Strengthening File Security: As Linux platform is an extension of the Unix-based file system, it is prone to multiple rootkits vulnerabilities and other service attacks. The rootkits are a set of software tools, which enables an unauthorized user to access a PC and corrupt the entire file system. In order to prevent or remove the deployment of these rootkits, experts use tools, such as chkrootkit and Intrusion Detection System (IDS). While the chkrootkit investigates nasty rootkits, IDS detects any security breach at any level.

SSH-level Security: The open SSH packages are by default installed in most of the Linux-based servers. SSH installation provides users with the best of the server functionalities and allows various utilities that could lead to security holes. To strengthen this area; certified engineers at web hosting companies perform a wide array of activities, including:

- Following stringent user authentication

- Accepting only secured SSH connections

- Changing the default 22 port

- Denying comprehensive access for the root logins

Security Measures: Ensuring strict security measure to safeguard network any against any potential vulnerabilities is critically important to ensure uninterrupted business functioning. In this light, lot of tools, such as netstat & nmap network mappers are employed by the third party vendors to determine ports/services accessible on the functional servers.

Thus, by implementing above measures a reliable third party service provider can effectively protect dedicated servers with Linux operating systems against data and security threats.
