We often get to hear stories about a breach of an unsecured server. It is important that you secure the dedicated server and take the required steps to keep sensitive data from being exposed. Protect yourself against the hackers who use the server to infect you with malware, criminal purposes, or ransomware.
There are various ways to gain access to a dedicated server. So, on the basis of the services running on the server, you should be careful not only with root server access but also with the security of the firewall, web applications, web server, email server, database server, FTP, and DNS.
Every service that runs on the machines comes with its own security issues. So, a weakness in anyone will put all of them at risk. In case you don’t have enough resources or time, consider managed server or secure server hosting. You can also check the cost of the dedicated server as per your configuration requirements.
In this article, you will get to know about the top measures you can take to secure your dedicated server. So, without further ado, let’s get on with it.
Stay Up to Date
Almost every software package or service you install on the server updates. At times, the updates are more frequent. Many tend to overlook or skip the updates. However, it is better to check for updates, periodically. This way you can decide if you have to install them.
You might not find it necessary to install every update, but you do not want to be left behind as this can cause you to depend on outdated services. The older a version is, the more susceptible it can be.
Remove Programs You Don’t Use
When you check the processes running on your home system, you will notice that there are many programs that you didn’t know were running. Similar is the case with a web server. It can launch many services by default. But what is necessary depends on what you require. In case you do not use services that log a user on a service, disable them.
Don’t forget, to uninstall a service or program, you have to try and test if you want to use it. You can easily forget about things like this. So, a periodic update is important. It’s a food practice for extending the website where you can also install programs to check them.
Limit Access to Secure Dedicated Server
All operating systems develop a root user that accesses everything. Surely, you need to change the root credentials for securing a passphrase or password. It is better to avoid using root users for everyday server access.
Rather create a user who gets limited access, and a log is as the user. Whenever you need root access for doing something on the server, you can get it using the ‘su root’ command and inserting the root password.
When you log in as a restricted user, you can block the root user from logging in through SSH. This defeats an attempt by the hacker to breach a root login.
Also, it is better to limit the total users having access to the server. You should make consistent password changes. No one likes to change their password. However, the longer the password, the greater is the chance to compromise.
Ultimately, in case you are allowing multiple users to access the server, ascertain that they are logging in using trustworthy networks whenever they can.
The server security is as strong as the weakest link. In case a user logs in while sitting at a coffee shop using the public Wi-Fi, their credentials might be at risk.
So, the best way to secure the dedicated server is to ensure that the server users are using sound security measures.
Backup Data to Secure Dedicated Server
Many users of dedicated servers practice backing up the operating system and the whole server. These types of backups serve a certain purpose. However, in case anyone compromises the operating system, it is like a backup too. This is the reason a reinstallation of the operating system is a good idea.
Nevertheless, if the data in the server has a different story, make sure you back it up as often as possible. The backups should live on the server. You should back up to cloud storage or other locations to secure the dedicated server.
Execute Vigorous Password Policy
If you acquire a new dedicated server, make sure that you change the password. It is because the host might set a default password, which makes you more vulnerable.
So, as an organization, you should use a random combination of numbers, upper and lower case letters, and symbols to set a password. Make sure it isn’t connected to your personal identity, and also avoid keeping the password for a long time. Furthermore, do not keep a password for a long time.
It is easy to install an application on dedicated servers. So, the risk of malware is quite high. Malware can easily copy confidential and sensitive databases. They can be bundled with legitimate application scripts.
Encrypt Data Transfer to Secure Dedicated Server
Choose secure protocols rather than unsecured protocols to communicate over the network. You also have to change the default port setting. This will make it challenging to enter into the brute force attacks, making the server vulnerable. It might not ensure complete safety or secure dedicated server, but it can definitely stop attacks to a great extent. In case you have joined hands with a third party, the communication is kept encrypted. If you want, you can install an SSL certificate for the site to encrypt the online transaction.
The Top Server Security is the Tip of the Iceberg
Sure, you can secure a dedicated several. It requires attention to detail and a proper maintenance plan. A majority of cyber-criminals are not fools. They tend to be more devious than you are. Hence, it is better to leave no stones unturned. Being vigilant will always keep the bad guys at bay.
