The issue of virtual server security is quite acute, as there are a large number of special protection technologies, among which it is not so easy to choose the most effective ones. In this guide we will consider the best options for VPS hosting security. You should devote more time to this issue and then the result will really amaze you.
What is VPS Security?
The VPS method treats the host server as resources and "regular hardware". Hostings apply hypervisor, which allows you to use "ordinary iron", more precisely the server and distribute it to several VPS. Such instances undergo the virtualization process in a separate autonomous environment. In this environment, security risks are minimized, as the hypervisor is not available in a shared network. In simple terms, a VPS system is very secure, and even more secure than shared hosting. When we talk about this security system, the following criteria should be heeded:
- Downloading patches and updates;
- Controlling the server;
- Server improvement;
- Protection from DDoS attacks;
- 24 by 7 support;
- Weakness scanning services.
The mentioned services are considered very important when it comes to the overall system of reliable VPS hosting.
Can a VPS Be Hacked?
In fact, all hosting platforms are not 100% safe from cybercriminals. However, these days, a VPS system is rightfully considered one of the most technologically advanced and secure. In part, each VPS instance is a separate autonomous virtualized environment. In simple words, it is similar in its properties to a dedicated server in that the files, operating system and software are isolated and highly remote from other parts.
Does a VPS Need a Firewall?
Hosting becomes more secure with the use of VPS, so the short answer to the question about the need for a firewall is positive. It should not be forgotten that threats on the open network are constantly evolving, and their developers are finding new and new ways to gain access to sensitive private information of individual users and even entire organizations.
It's not so rare that web hosts don't use cybersecurity methods at all, which undoubtedly makes them tidbits for hackers. It can be said that a VPS has a high level of security due to its dedicated nature, but with the use of a firewall, it goes even higher. Proper use of a firewall allows you to eradicate traffic with malicious software before it reaches the server.
Why Use a Managed Server vs Unmanaged Server for Security
The most important advantage of a managed server over an unmanaged one is that it provides access to technical support around the clock. This feature is key in the matter of emergency situations. A team of trained professionals will always help to fix any error and can protect your hosting from the latest viruses.
When it comes to unmanaged servers, there is no support as such. Everything depends directly on the server owner, who takes the maintenance of the network on his shoulders. Also in the list of duties of the owner of the unmanaged server falls responsibility for network protection and backup. Obviously, one person can not keep track of all these processes at the same time, so often the solution is to hire a specialist and in the purchase of special software.
Does Managed Hosting Include Updates and Patching?
The answer to this question largely depends on the chosen provider that manages your hosting. Modern vendors offer their customers regular updates with automatic downloads. Such patches are aimed at promptly solving old problems and new threats. If the hosting is not updated, sooner or later it will become vulnerable to malicious attacks. Unmanaged hosting also comes out, but their search and installation is carried out manually.
How Do Managed Server-Level Backups Work?
The distinguishing feature of managed servers is the constant access to software that provides backups. These backups are regularly scheduled and most often made daily, allowing you to protect the most recent form of your data. The backups are stored in your server inside the cloud. So in the event of an attack and important information is lost, all you need to do is go to the cloud and restore your site with minimal loss.
In unmanaged servers, the possibility of backup is rare. For the average person, this means only one thing - finding solutions to perform manual backups. This task is not difficult for experienced professionals who create customized software, but it does not always work correctly, and failures can lead to severe losses of time and finances.
Do Managed Servers Come with Security Protection?
Most managed servers have security protections that are aimed at defending against DDoS attacks. This type of hacker attack is a bombardment of the server with packets of files until it overloads and stops working. In this matter, you should contact your hosting provider who provides full information about the security systems of their servers.
Does Managed Hosting Offer Virus Protection?
Antiviruses are considered a standard for every managed hosting service, as they work on their own and prevent almost all threats from outside. Of course, a lot depends on the quality of the antivirus, but modern programs are notable for their accuracy in operation.
Do Managed Servers Have Automatic Upgrades?
Up-to-date hardware software is very important for VPS security. Regular and timely updating of components allows you to get maximum storage performance. In addition to improving efficiency, additional systems are used to ensure data security, such as risk monitoring. Managed servers are equipped with regular technical improvements and ensure smooth operation of the entire system.
Why Should You Choose Managed VPS Security
Managed VPS hosting is objectively better than its unmanaged counterpart. Of course, the second option can be a great solution in case you have your own experienced team that is ready to face any complexity of problems. Setting up a properly functioning unmanaged hosting from scratch will take a lot of time and skill. That said, most of the time and effort will be focused on ensuring an acceptable level of security. If you are a simple commoner or a good specialist, but you do not have a professional team, then it is best to choose exactly managed VPS hosting.
How to Properly Secure Your Server
To eradicate all kinds of risks, it is enough to implement special protocols in order to protect the server. Let's look at the main tips based on common sense and proven solutions that can significantly strengthen the protection of VPS servers.
Create A Strong Password
The most obvious way to protect your own information and network is to create a complex password. For the server it is necessary to use passwords of 15 characters or more, including lower and upper case characters, special characters and numbers. Such passwords, as practice shows, are simply impossible to generate or guess.
Use Secure File Transfer Protocol (sFTP)
Encryption of information is an effective method of protection and sFTP protocol is suitable for this purpose. This technology uses two channels, including the command and data channels. The user is given the option of encrypting both channels, which is enough to maximize the security of sensitive information.
Install SSL Certificates
The SSL certificate acts as another encryptor that encrypts information during transmission, making it impossible to steal data during transmission. Even if the cipher is in the hands of a hacker, the hacker will not be able to break it.
Closing Unnecessary Network Ports
It is best to close unnecessary ports immediately. Otherwise, they can be used for unauthorized traffic.
Set up a firewall
Using firewalls greatly improves VPS security protection. It is very important to responsibly approach its inclusion and configuration right after you start the server. This software quickly searches for and prevents hacker attacks.
Malware and virus protection
Installing a quality antivirus is considered a mandatory precautionary measure that plays a huge role in protecting the server. It is recommended to use proven and licensed software, as it is capable of detecting and removing even the most hidden viruses.
Cleaning spam is very important as it prevents hacker software from getting inside your server and into your users' devices. It will also make working with email much easier.
Limit root access
Restrict root access is considered another effective method to strengthen VPS security. This login grants full access to the servers. Since root login is considered to be "root" by default, it leads to attempts of brute force hackers to obtain account access information.
Change the default SSH listening port
Port 22 is actually the SSH port that is open by default. To protect your server from most of the initial attacks, you can simply change it.
Ensure brute-force attack protection
Brute-force attacks can be protected in many ways, but the best way to do this is with a firewall.
