Server hardening is a necessary process. And it’s a never ending one. From the moment you pull the machine out of the box (or create it in the virtual environment), it pays to be thinking about security. But server hardening can do more than keep your machine safe. It will help with performance, and it can even play a part in keeping your machine online and available.

Server Hardening is the process of enhancing server security through a variety of means which results in a much more secure server operating environment. This is due to the advanced security measures that are put in place during the server hardening process. Server Hardening reduces the increasing amount of dynamically emerging cyberattacks, information systems and servers especially need to get hardened.

Server Hardening, probably one of the most important tasks to be handled on your servers, becomes more understandable when you realize all the risks involved. The default configuration of most operating systems is not designed with security as the primary focus. Instead, default setups focus more on usability, communications and functionality. To protect your servers, you must establish solid and sophisticated server hardening for shopping store policies for all servers in your organization. Developing a server hardening checklist would likely be a great first step in increasing your server and network security. Make sure that your checklist includes minimum security practices that you expect of your staff. If you go with a consultant you can provide them with your server hardening checklist to use as a baseline.

Server Hardening Guidelines

Every server security conscious organization will have their own methods for maintaining adequate system and network security. Often you will find that server hardening consultants can bring your security efforts up a notch with their specialized expertise.

Some common server hardening guidelines include:

  • Use Data Encryption for your Communications
  • Avoid using insecure protocols that send your information or passwords in plain text.
  • Minimize unnecessary software on your servers.
  • Disable Unwanted SUID and SGID Binaries
  • Keep your operating system up to date, especially security patches.
  • Using security extensions is a plus.
  • User Accounts should have very strong passwords
  • Change passwords on a regular basis and do not reuse them
  • Lock accounts after too many login failures. Often these login failures are illegitimate attempts to gain access to your system.
  • Do not permit empty passwords.
  • SSH Hardening
  • Change the port from default to a nonstandard one
  • Disable direct root logins. Switch to root from a lower level account only when necessary.
  • Unnecessary services should be disabled.
  • Hide BIND DNS Sever Version and Apache version
  • Minimize open network ports to be only what is needed for your specific circumstances.
  • Configure the system firewall (Iptables) or get a software installed like CSF or APF. Proper setup of a firewall itself can prevent many attacks.
  • Consider also using a hardware firewall
  • Separate partitions in ways that make your system more secure.
  • Disable unwanted binaries
  • Maintain server logs; mirror logs to a separate log server
  • Install Log watch and review log watch emails daily. Investigate any suspicious activity on your server.
  • Use brute force and intrusion detection systems
  • Install Linux Socket Monitor Detects/alerts when new sockets are created on your system, often revealing hacker activity
  • Install Mod security on cheap vps as Webserver Hardening
  • Hardening the Php installation
  • Limit user accounts to accessing only what they need. Increased access should only be on an as needed basis.
  • Maintain proper backups
  • Don’t forget about physical server security


Computers are just machines. They need to be treated with care and not abused. Streamlining services, restricting access, and limiting vulnerabilities will make your server healthier and you happier. If you don’t harden your server now, you may very well be sorry in the long run.

SD-WAN, short for Software-Defined Wide Area Network, is a cloud-based system that allows businesses a highly improved WAN experience through changes in the configuration at which WAN routers work.

To simplify, SD-WAN is a simple, cost-effective and highly flexible technology that’s fast replacing conventional WAN solutions by enhancing the performance of applications based in the office premises and in the cloud.

Here are 5 reasons why businesses globally are opening up to SD-WAN, which is rapidly redefining the way branch offices connect with the head office and with each other.

Simplified networking

SD-WAN solutions simplify the way branch offices use wide area network to communicate with each other. It enables several devices and services to work in tandem, thus bringing never-before agility to your branch operations. The inherent application programming interface (API) allows all your systems to communicate with each other, delivering greater coordination between various enterprise solutions being used by the business.

Lower costs

Deploying SD-WAN helps make significant cost reductions by upgrading ordinary WAN to business-level broadband-based WAN. The cloud-based system ensures that you don’t have to invest in building a network of expensive hardware across branches. Consequently, maintenance costs also come down over time.

Never-before flexibility

This disruptive technology empowers the hybrid WAN to adapt to all kinds of network conditions with minimum intervention. This leads to greater savings on time, money and other resources for your IT team, as they no longer need to build as many new circuits or deploy additional infrastructure.

Improved security

It is well known that conventional WAN systems handle security by way of multiple devices placed at each of the branch offices. This method is both cost-intensive and effort-intensive. SD-WAN, on the other hand, can insure high-level security for your cloud network operations by integrating into the system all possible security measures—from protection against malware to filtering of web content to botnet control.

What’s more, SD-WAN can do this remotely for each of your devices at a much lower cost.

Greater control over pathways

SD-WAN is an agile, user-friendly technology that is programmed to offer intelligent pathways control. This means that traffic is maneuvered and forwarded based on the application. All of this is achieved through a central traffic controlling capability, which works for all devices in the system. This system can be programmed to respond to a number of parameters, such as time of the day, IP address, port number, and more.

To conclude, enterprises today are increasingly looking for advanced cloud-based solutions that can help elevate the performance of their existing WAN systems as well as the applications they support.

With the enormous amounts of data that is transferred on a daily basis across branches, centralized data centers and the cloud, SD-WAN has emerged as a cost-effective, responsive, and reliable solution to traditional WAN woes businesses have been grappling with for decades. Adopting SD-WAN technology is the prudent next step if you’re looking for a networking system with high-quality capabilities to cater to the needs of your growing business.

Setting up a website is not the most difficult thing in today’s world, however, before venturing into the unknown, one must be aware of the Knick knacks of the trade. One of the many dilemmas a first timer faces is choosing the best server for hosting. Whether to choose a Linux Server, which is currently most popular, or a Windows Server for web hosting, depends upon the specific user demand. Let’s see a brief comparison between the two server hosting options, which might help you with the choice.


While looking for a hosting service, this is the most important characteristics to seek. Linux servers are more stable as compared to the Windows Servers. It has been seen that websites hosted on Linux Servers have experienced an uptime of almost hundred percent, in fact, Linux Servers are rarely rebooted. Also, Linux Servers are known to be comparatively stable with running a wide range of web applications.


There has been a rise in BitLocker hacks which are mostly targeted towards windows machine putting Windows Servers at more risk as compared to the Linux Servers.


When it comes to affordability, Linux being an open source system is way cheaper than Windows Servers for web hosting. While, Windows Servers cost more, the fact that there are constant updates available, can’t be overlooked.

Ease of Use

Configuring and deploying a Windows Server is comparatively easier than Linux Server. For a beginner Windows Server might not seem too daunting whereas Linux might be a bit overwhelming. But, if a user is well acquainted with Linux command line and can configure a web server like Apache or NGINX, then it might be a good choice to deploy a Linux Server. If one seeks to install a third party application, then on a Linux Server, it can only be done by a system administrator. From a system updates, in a Windows Server, the updates are easy and can also be automatized whereas updates for a Linux Server might be a little trickier some times.


It is ideal to choose a Linux Server hosting if a developer uses PHP, Perl, Python, or MYSQL. Say, if a user seeks to setup a blog using WordPress, then Linux Server is the way to go. Windows Server might be a good choice if the user needs specific Microsoft Windows based technologies such as MSSQL. Since, applications like Exchange and SharePoint belongs to Microsoft, they are exclusively for Windows Server. A belief that, one can only use a server that is analogous to the operating system they are using, has no ground. A user working with Windows operating software can still use a Linux Server for web hosting.

I hope that you might at least have a faint idea of which server to choose for web hosting, but, it still is largely defined by the user’s needs. One must closely analyse their necessities and the expectations before buying or renting a web hosting server, be it the Linux Server or the Windows Server.
