The importance of securing your dedicated server
Regardless of whether you are working with a managed or unmanaged dedicated server, security care is important when it comes to the maintenance and security of dedicated servers managed by your hosting company. Many websites may be hosted on a dedicated server, but only one person or business has full control over them. As you read the exclusive article on dedicated servers, you know that having a dedicated server means you have full control over your server. On the other hand, this means that it is entirely up to you to configure and guarantee dedicated server security to protect your server.
But why the security of a dedicated server is that important?
- Software called malware is used to steal data. Usually, it is hidden and distributed alongside trusted programs or scripts. If it is on your server, it will try to collect your data. By choosing a hosting company that offers continuous vulnerability scanning and real-time server monitoring, you can best protect your hosted apps from malware.
- One of the main methods used by hackers to gain access to dedicated servers is to use short, weak passwords. Creating passwords with a random assortment of letters, numbers, and symbols will prevent them from ever being cracked. For Control Panel, FTP accounts, and your mail services, you should use different passwords. Of course, it’s also a good idea to change them frequently.
- The software on your server is vulnerable to hacker attacks, giving them access. You should only install software that receives regular updates and ensure that you run it with the most recent security patches, exploiting such vulnerabilities to prevent such security breaches.
- Preventing DDoS Attacks: A denial of service attack involves overwhelming your server with traffic and spam in an attempt to take it offline. If you fall victim to this significant cyber threat, it will cost you time and money. Choose dedicated servers to plan with built-in DDoS protection to prevent damage to your hosted site from a DDoS attack.
Tutorial Secure Dedicated Server
Depending on the type of security breach we are talking about, there are different methods to secure your dedicated server. This tutorial tries to collect the most used and helpful methods for securing a dedicated server. Dedicated server maintenance is not complicated. You just need to know how to change settings and adjustments. We have discussed 11 ways to secure a dedicated server in this article. Stay tuned to review the most used tips for dedicated server security.
Security Procedures 1. Check for software updates regularly
Delaying updating to the latest security patches can also be harmful. So you should check for software upgrades regularly. When a new software update is available, install it on your dedicated server Use a trusted dedicated server security scan to stay current and secure.
The most common vulnerability that hackers take advantage of is outdated software. Most app developers deploy regular security updates that fix any flaws in the security of their programs. If you don’t download some of these fixes, someone could exploit a vulnerability that remains unpatched. Do not rely on outdated services or programs. If you use older software, you may not have the necessary patches, security upgrades, and other safeguards to protect your data.
Security Method 2. Set up regular data backups
Always back up your important files. You will probably experience data loss at some point. No matter how many security precautions you take, things can go wrong due to hacker attacks, hardware failures, or natural disasters. You should have many, you can, for example, maintain two backups; One on a hard drive in your office and the other on a secure, dedicated server. But, never keep all backups together. At least one of them must be offsite. For further clarification, you should not keep your backups on a dedicated server. Always make a backup in a different place or cloud storage.
To do this, consider the options below:
- Physical security is required.
- It should be far enough away from the primary backup location.
- Both access and verification are required.
Security Method 3. Protect your database
Cybercriminals target vulnerable databases. So, you must take care of your database security. Make sure your database can withstand SQL injection to avoid a breach. A SQL injection attack involves inserting malicious SQL statements, which can alter the data in your database. To secure dedicated servers, you should try to limit everyone’s access to your database as much as possible for maximum security. You can accomplish this by lowering user rights. Also, delete any unnecessary services and files. Especially when you have collected important and sensitive information about your clients, observe the following options to avoid neglect:
- Limiting the privileges of database users.
- Delete unnecessary data.
- When not necessary, avoid areas where customers and databases interact.
Security Method 4. Scan regularly and use DDOS protection
A DoS (Denial of Service) attack overloads the system with traffic, leading to server failures and unavailability. A DDoS attack is a type of DoS attack in which numerous criminal computers collaborate to drain your hardware resources, overwhelm your servers with traffic, and harm your valued customer experience. Preventing DDoS attacks is important because they make your website or web apps inaccessible to users. Choosing a DDoS-protected dedicated server is the only option to protect against these attacks. These servers have built-in DDoS protection that will monitor all incoming traffic. Connection requests are redirected away from your server when malicious traffic is detected Plus, legitimate traffic is allowed to proceed, ensuring your users don’t experience any bottlenecks.
Also, for regular testing, consider the options below:
- Select a hosting company that provides regular vulnerability scanning.
- Check your website for strange behavior.
- Before placing any software on your website, test it on a personal, secure home computer.
Security Procedures 5. Enforce a strict password policy
It is very important to change the password whenever you purchase a new dedicated server This is because your host may use a default password that increases the likelihood of a vulnerability. If you use weak passwords, your dedicated server is more susceptible to brute-force attacks. You should use uppercase and lowercase letters, random numbers, and symbols to create a strong password.
Avoid using personal or words that are easy to guess as your password. The same is true for each additional user account you create. To secure a dedicated server, each person should have their own strong password. Passwords should also be changed regularly on every predetermined day. This virtually eliminates the possibility of hackers entering your password or your account by brute force. In addition to these security measures, consider enhancing your accounts with two-factor authentication. Your dedicated server will be protected from unauthorized access in this way.
Security Procedure 6. Delete old and unused software
A web server also automatically starts many standard services. Of course, what you need will depend on your needs. Disable user-logged services on the server, such as FTP, if you do not use them. Unused software is easy to ignore, and it won’t get security upgrades if you don’t open it. This is especially true for apps and services that you use once before you forget Unused software can be exploited by hackers to gain access to your dedicated server and steal personal data. Just remove unnecessary software is the answer.
Security Method 7. Buy a managed dedicated server
You are advised to purchase a managed dedicated server, not an unmanaged server. Managed dedicated servers are managed by a team of IT professionals who will keep all your databases and software up-to-date, back up your data regularly and constantly check for suspicious activity. The hosting company takes care of every aspect of server security. So, you are advised to use a managed dedicated server which is a service offered by most hosting providers. Generally, if you don’t have the time or the necessary expertise, your dedicated server security can cost you thousands of dollars. Contact the experts who will take care of your dedicated server.
Security Procedures 8. Create separate accounts for each user
To secure a dedicated server, it should only allow system administrator root access. Each operating system makes a root user with administrative privileges. The root certificate should, of course, be replaced with a secure password or passphrase. Also, it is recommended to avoid accessing the server as root on a regular basis. Each user of the server should have their own account with only the required permissions. This way, it will not be possible for anyone to install software that could be harmful.
Only server administrators should have access to these permissions. Other users may have limited access, allowing them to perform only their tasks. Also, with the “su root” command and the root password, you can get root access whenever you need to perform a task on the server.
Administrators can also have a personal account. Logging in with root access is not always recommended if you forget to log out of the admin account. Finally, if you allow many users to access the server, make sure they are always connecting over a trusted network.
Security Method 9. Select only secure networks
To ensure a secure dedicated server, it is recommended that you only use secure connections to log into your hosting account when connecting to your dedicated server. Public networks are insecure, and the security of your dedicated hosting account depends on how strong the network link is. If you use an open WiFi network at a hotel to log in, your login information may be made public. So you should only use reputable networks. Your server’s security is only as strong as its weakest link. Also, if a user checks in from somewhere using an unsecured Wi-Fi connection, their login information can be stolen.
Security Procedure 10. Change the SSH port
A common SSH port is used by many services. In order to compromise the security of your dedicated server, hackers are aware to target that specific port. The most open port is the SSH listening port. Hackers use scanning tools to find hosts that have not changed the SSH port because it is set to 22 by default. Change your SSH port now to thwart brute-force attacks. This can be changed to any other port, however, it is recommended that you change it to a value greater than 1024. Port scanners usually operate within a predefined range and rarely scan above 1024. By doing this, you can prevent automatic scanners and bots from seeing your SSH port.
Security Method 11. Use a Good Firewall
If your server has any vulnerabilities, attackers can exploit them to misuse sensitive and confidential information. So, to get a secure dedicated server, choose a dedicated server with top-notch hardware and enough system resources. To prevent harmful data from reaching your servers, choose a hosting company that offers a good perimeter firewall.
