Servers are important because they store confidential company data and information. Data resembles gold these days, and programmers are gold excavators.
All kinds of security threats and data breaches can occur on a server that is not secure. On the off chance that you don't get your servers, then you are stepping a risky way.
In this article, we'll go over a few server security tips which you can use to keep your servers safe: Set up server security with a firewall: One of the most common practices to secure your server is to use a firewall. A firewall blocks unauthorized access to your system by filtering traffic at the network level. It allows authorized users and programs through while blocking unwanted traffic and malicious software.
- Use SSH Keys Authentication: SSH keys authentication is a popular practice to secure your server. It's also one of the simplest practices you can do. By using SSH keys authentication, you create an encrypted login key that can be used by only authorized users. This prevents unauthorized individuals from gaining access to your server, and it increases security because they won't be able to masquerade as someone else to attack or steal data.
- Change SSH port: SSH is a secure protocol that allows computers to remotely access servers. It's commonly used for remote administration. By changing the port, the user can protect the server from prefined scripts that target port 22.
- Allow ports and block other ports as per the services: Allow ports in services as per services. The common ports which need to open are 80, 443, 53,21,22, 3306, and 1433.
- User-paid security tool: Server security is a top priority for any business. However, securing your server can be challenging and time-consuming, especially if you're on your own. That's where paid security tools come in handy.
One of the most popular paid security tools is Imunify 360. This platform provides users with real-time protection against viruses, spam, spyware, and other malicious attacks. It also offers malware removal capabilities and secure file-sharing features to keep your files safe from prying eyes.
- Use SSL: To protect your website and data from unauthorized access, you should use SSL ( Secure Socket Layer ).SSL Certificate secures connections between your web browser and the server. It helps to prevent eavesdropping, data theft, and other malicious activities by encrypting the information exchanged between the two parties.
- Plan your backup server: Backups are essential for any business - even those that don't have sensitive data stored on their servers! Backups allow you to restore your server should something happen that disrupts its normal operation. By regularly making copies of important data (such as databases), you ensure that in case of an emergency, you will be able to get back up and running as quickly as possible without losing valuable information
- Monitor the server using some tools: Server security is essential for any business, and it's especially important for online businesses. One of the best ways to secure your server is by monitoring it using some tools.
Some popular options include the Plesk 360 subscription, which gives you access to various features that can help monitor and protect your server. These features include vulnerability scanning, performance analysis, and log file analysis. Additionally, Plesk 360 provides real-time alerting when there is suspicious or unauthorized activity on the server.
- Change password from time to time: Another common practice is password protection. This protects your server against unauthorized users by requiring them to enter a valid username and password before they are allowed access to restricted areas or files. Password protection can also help you keep track of who has accessed which files, regardless of whether they were authorized or not.
- Update and Upgrade OS, hosting panel, and server versions(Apache, IIS) Regularly: This will help keep your computer protected from viruses, spyware, and other malicious software. Additionally, it will ensure that your website is running at its best performance. Additionally, always use caution when accessing or downloading information from untrusted sources online.
- Hide Server Information: The most common practice to secure a server is to hide its information. This means configuring the server so it does not reveal its IP address, name, or other identifying information. You also need to create secure passwords for all of the user accounts and make sure that these passwords are not easily accessible or known by others.
- Disable port 25: By disabling port 25, you are preventing attackers from sending unsolicited e-mails or connecting to your computer through unauthorized remote access attempts. By blocking the outgoing traffic on this port, you will limit other people's ability to access your computer or network.
Thus, in conclusion, the more security measures you have, the safer your server will become.
