Whether you are running your own server or a shared server, you can protect your VPS from hackers with a few simple steps. Here are five tips for ensuring the security of your server.
Modifying the default SSH port
Changing the default SSH port on your Linux VPS can be a great way to protect your server from hackers and automated attacks. In some cases, a change of this magnitude may even allow you to SSH into your machine when you’re traveling. It’s important to make sure that your firewall is setup to permit SSH connections to your new port, though.
Depending on the type of server you’re using, you may have to edit a number of firewall rules to enable SSH connections on your new port. Before making changes, be sure to practice the new configuration on a local test environment.
Another good reason to change the default SSH port on your Linux VPS is to prevent brute force attacks. A brute force attack is when a hacker attempts thousands of possible passwords for a specific account. This is a very common method of gaining access to an otherwise secure server. In order to avoid this, it’s best to set your SSH port to a random four-digit number.
To change the default SSH port on your server, you’ll need to open the SSH configuration file. This is usually located in /etc/ssh/sshd_config.
Depending on the type of operating system you’re using, you’ll need to use a variety of different tools to perform this task. For example, you can open the file with nano, or you can use a more sophisticated tool like vi.
If you’re running CentOS, you can also edit the SSH configuration file from the command line. In this case, you’ll need to do the above steps, but then you’ll need to restart your SSH service. Once the process is complete, you’ll have to verify that you’re now connected to your server on the new port.
Changing the default SSH port on your VPS is one of the easiest ways to increase the security of your server. It’s a small investment that can provide a big return. But you must be careful not to forget about other small-but-important things that will help ensure that your changes have the desired effect. And, of course, you should never close your SSH connection until you’ve checked that you’re still connected.
Adding a firewall
Adding a firewall to your VPS is a must to maintain security. A good firewall will help to keep your VPS safe from malicious traffic and DDoS attacks. In addition, it will allow you to monitor events that occur on your VPS. This will help you identify and resolve issues faster.
You can manage your firewall by accessing the Control Panel. The OVHcloud Control Panel allows you to set up up to 20 firewall rules per IP.
You can also add an IP address by going to WHM and clicking on “Add IP to Firewall”. After you type in the IP address, you will see a link for “Add IP to CIDR Converter.” This link will allow you to convert the IP to a CIDR format. You can then add the IP to the firewall.
To create firewall rules, you will need to know the target zone and the services that are being used. You can choose the target zone by network tags or a specific name. You can also define the action that should be taken on a match. You can deny or allow a service. You can also decide if you want to allow all users to use the service.
During an attack, the OVHcloud Control Panel will automatically activate the firewall. You can also check the firewall rules on a regular basis. If you find an issue, you can contact your host support team to get the best solutions.
Another way to monitor your VPS is to use the OVHcloud Control Panel’s Bare Metal Cloud menu. You can access this menu from the left menu in WHM. This menu provides access to the following options: Configure and Manage Firewall, Create Firewall, and Open/Close Ports.
Adding a firewall to your VPS may not be necessary for every setup. You may need to disable certain port scans or open the most commonly used ports. You may also need to add support for specific applications.
The easiest way to determine what ports are open on your server is to monitor the logs. You will be able to find out if there are any suspicious requests or malicious traffic.
Adding a malicious activity detector
Adding a Malicious Activity Detector (MAD) to your firewall is the cheapest and quickest way to ensure your digital assets are protected. It’s a known fact that hackers are on the prowl for your data and with a Malicious Activity Detector on hand you can ensure that no malware has been installed on your system. The software is easily installed on Windows and can be found in your Start Menu.
The MAD is a small program which limits the amount of CPU and memory usage preventing malware from wreaking havoc. The best part is that you can choose which IP addresses to block and what ports to allow, allowing you to block malicious traffic without a tinkerer in the house. If you are a Linux aficionado you can also daemonize the MAD in order to run it automatically. You should then follow this up with an FTP framework upgrade to stop unidentified FTP uploads. Fortunately, you don’t have to be a security guru to do this, as there are many tutorials out there to help.
The latest version of the MAD is now available on the SolarWinds line of firewalls. To make sure your data is safe, be sure to review the products you’ve purchased and ensure that they match your needs and budget. You’ll also want to look at the upcoming product releases and upgrades as these will give you the most bang for your buck. If you’re considering a VPS, be sure to investigate the best options around and get a free trial to test the waters before making the leap. This will prevent you from being a victim of hackers in the future.
Taking regular backups
Taking regular backups is important for any business. Without them, you may suffer from data loss and website malfunction. Using antivirus software can also protect your files from vulnerabilities and ensure that they are safe.
The OVHcloud Control Panel offers VPS backups. You can choose to back up your data to a remote location or to an external device. This ensures that important data is protected and you have peace of mind. You can also use an SSH connection to access your backups.
You can also choose to set up an automated backup routine. With this option, you can schedule your backups so that they are automatically taken on a daily basis. This means that there is less chance of forgetting to do it.
Another option is to create incremental and differential backups. These are useful in supplementing a full weekly backup. You can also backup the entire server to a remote location. This will help you reduce the risk of data loss and will also save your data more often.
The OVHcloud Control Panel also offers an SSH backup interface. With this interface, you can connect to your VPS and access your backups. You can also monitor your system and software to help you resolve any errors.
Taking regular backups is not only a necessity for your business, it is a necessity for your peace of mind. Your computer can be vulnerable to malware, so you need to have firewall software installed and configured. If you are transferring sensitive data, it is advisable to use an encrypted connection.
Your VPS should be secure at all times. You can do this by following the steps outlined above. You can also check your logs to ensure that your VPS is running properly and not causing any problems. If you do notice any problems, you can get expert assistance from the Managed Support Team. They are available 24 hours a day and can solve your problems quickly.
Keeping your VPS safe is important, but it is even more important to make sure that you are taking regular backups. A backup of your VPS can be used to restore your server should you need to. You can also access your backups at any time.
