Strengthen Your Linux Web-Server Against Any Data And Security Breaches
Your Linux server is the back bone of any hosting service or solution you do offer in any manner to your clients. The complexity and credibility of the servers make it very prone to the visible and virtual security threats against data and information. Web hosting service providers now start visualizing server security as a very comprehensive process. Interestingly, the process of securing the web servers is comparatively tedious than breaching it. The key motive behind the Linux server security is to create a protection wall against a wide variety of threats prevalent in the area of server functioning. Among several security measures, below illustrated are some of the key aspects of server security to be implemented.
SSH Level Security:
The OpenSSH package is installed on the many of the Linux servers by default. This default installation is primarily offers best of the server functionalities and shows lesser concerns to the security lapses. SSH allows many utilities that could be the primary reasons of security holes. Allowing root logins and listening to port 22 may be the topmost causes of security breach. Experts at a web hosting company usually perform several activities to strengthen this area:
- Avoid to offer a clear access for root logins
- Accept only secure SSH connections
- Change the default 22 port
- Allow strict user authentication
Strengthen the file level security:
Being an extension of the Unix file system, Linux is prone to the Denial of Service attacks and many rootkits vulnerabilities. Web hosting experts indicates that rootkits are primarily very dangerous as it can intrude in the entire internal file system after initial access. In order to remove or prevent the deployment of rootkits, web host experts utilize the tools like chkrootkit in core combination with Intrusion Detection System. Chkrootkit searches for the envious rootkits and IDS checks for any violation in the security measures at any level.
Network Security measures:
When it comes to the vital server security aspects nothing comes more prominent than the network security for the Linux servers. The primary responsibilities of the Web hosting solutions providers are to ensure stringent network security features by managing the port interconnection process.
Numerous tools however are used by the web hosting services providers to determine the security threats in Linux server. These tools include netstat and nmap network mappers. Both of these tools are meant to determine the ports and services available on the functional servers and also very easy to access. Its further use to display exhaustive information regarding several prominent network activities.
