Jan 31, 2020

There are several reasons why businesses opt for a dedicated server. Unlike the shared hosting server, the dedicated server is completely yours, and you get to configure it according to your business requirements. However, there are also many things that make a dedicated server vulnerable. The control dedicated server offers is one of the most crucial factors of it.

Although when it comes to safety, cloud technology is highly reliable. Salesforce reports that 94% of businesses proclaim significant improvements in online security after moving their data to the cloud. A dedicated server offers complete console access; the level of control provided also arrives in with lots of responsibilities. According to Gartner’s cloud computing stats, more than 90% of breaches are the user’s fault and not the provider’s. With dedicated server hosting, other than the responsibility of the hosting provider, you, too, have the responsibility to plan on the necessary steps to avoid any type of security breach and to protect the server from any type of online threat.

In this article, we discuss the security landscape that surrounds the dedicated server functioning, security threats along with the respective solutions are mentioned in this article.

Read on to understand the four most common types of security breaches for a dedicated server hosting environment.

  1. Breach of security due to malware on your dedicated server

Malware is a various different type of coded software that is created to steal data from your server. Malware, in general, is used as a term to refer to worms, viruses, trojans, and spyware. The functionality of these applications is different, but they surely incorporate the collection of every confidential information and copy and stores the most critical data in the database. Malware is at-times coupled with legitimate applications or scripts. Hence it is recommended that users make it a habit to scan every application or file before running it on the server.  Because malware can copy most of your confidential information and sensitive databases. Since it is easy to install applications on a dedicated server the risk of malware is usually high.

Security Measures:

  • The website hosting provider must check the website regularly and test it for any unexpected behavior. 
  • Advertisements and invisible frames must be tested.
  • All the software applications must also be tested. 
  • Testing must be done on a remote and secure device before uploading it to the website.
  • Look for a hosting provider that offers real-time server monitoring and on-going vulnerability scanning.
  • Select an excellent web hosting package that offers excellent security and abundant hosting resources.
  1. Dedicated Server Hosting Password Breach

High security and control are one of the main reasons why so many businesses choose dedicated servers for their website. However, hackers are still able to enter into the user hosting account and damage users’ data with more advanced technology and tools. Hackers have now become splendid and sophisticated and can get into your dedicated server account with the assistance of one of the most effective tools: your password. Unfortunately, many un-experienced dedicated server owners still have a highly weak and vulnerable password. A short and simple password allows brute force attacks to crack the password much faster than a complicated one. Strong passwords are great, first layer deterrent in dedicated servers.

Security Measures:

  • It’s preferable to use a random combination of upper and lowercase letters, numbers, and symbols.
  • Try not using words that are connected to your identity.
  • Don’t keep a password for a long time.
  • Do not use simple words that can be found in a dictionary.
  • Passwords should be changed frequently.
  • Wherever possible, log in through a secure SSL connection.
  • Make use of different types of passwords for every element of the dedicated server. Select one password for control panel, another for mail access and another for your FTP account, and so on. With this, you can ensure that even in case of a password breach, the hacker will not be able to gain complete access.
  • Whenever you enter the password, make sure it is not a phishing website.
  • Preferably, enter the web address manually. Do not access your hosting control panel through a link in an email.
  1. Denial of Service (DoS) attack on the Server

The DoS is a denial of service attack. It can cause a severe impact on the services of your dedicated hosting server. Businesses with a growing reputation become a prime target for DoS attacks. It is one of the most chronic threats for the stability of your server. DoS is a type of security breach that starts within your server. A Denial of Service attack is caused by flooding the system with traffic resulting in server failure and unavailability of services. A DoS attack involves many malicious computers in sync together to flood your server with spam and traffic. DoS attack can also result in the waste of hardware resources, and on the whole, can cause a negative reputation of the brand for the customers.

Security Measures:

  • Monitor your server for any signs of sudden traffic increase.
  • Assure that your hosting provider provides a quality perimeter firewall to obstruct malicious data before it gets to your server.
  • Choose the best possible hardware that offers the most generous system resources for your dedicated server.
  1. Vulnerabilities in Your Dedicated Server Software

More than a million businesses were at risk when the #1 eCommerce solution platform Magento that is used to power shopping sites worldwide was exploited. It is possible for your dedicated server to be breached through the software that runs on it. Usually, hackers scan for default open ports to attempt a brute force attack. The default port for Linux for SSH remote access is 22, and for Windows Remote Desktop Access is 3389 and should be changed. Typically, the default Linux and Windows configuration include several extra software that is unnecessary and can be accessed online. This software may usually have vulnerabilities that you may be unaware of. It’s a best practice only to keep ports open for services that your dedicated server is set up to use and close off any ports that you aren’t using. These are fundamental software security points that are sometimes overlooked. Securing them will help prevent a majority of attacks that are commonly seen against dedicated servers.

Security Measures:

  • User admins play a significant part in ensuring that your site remains as secure as possible. It is essential always to update your software to ensure that it has the latest security patches.
  • Ensure to use software that is actively updated and patched. Using outdated software makes you vulnerable to attacks.
  • Regularly update any web applications you use (for example, WordPress, Shopify) to ensure the latest security patches. The faster you update your site, the less chance of it getting exploited through a vulnerability.
  • Use a secure API that employs a parameterized interface.
  • Javascript Sandbox Tools, Auto-escaping Templates, and Content Security Policy are some of the most impactful control strategies that can be implemented to achieve a highly secure web hosting environment.

Conclusion:

Excellent value performance, greater control, and increased security are some of the noteworthy selling points for a dedicated server. Despite all of it, users having complete control without any experience can result in holes in the security of your server. In order to provide a perfect solution to this, users must follow the respective precautions mentioned in this article. Regularly troubleshoot your dedicated servers for threats like the ones listed above to ensure you are always protected, and make sure you know what you’re doing.
