What Is Imunify360? How It Protects Hosting Servers
What Is Imunify360?
Servers that host websites are always under security threats. Daily attacks consist of attempts to find out passwords, vulnerable applications, outdated software, and open server services. One successful attack may infect your website with malware, harm the data of your customers, drain server resources, or damage multiple websites hosted on the same server. Thus, the hosting provider needs not only a firewall but also a tool that would be able to detect and stop any attacks right away.
Imunify360 is a unique security system for Linux-based servers, which is designed by CloudLinux. The product integrates a number of security technologies in one solution rather than using different tools for firewall, malware, intrusion prevention, and other issues management.
As compared to general endpoint security applications, Imunify360 is designed for hosting purposes. The application knows how hosting, VPS, reseller hosting Melbourne, and dedicated servers work. Therefore, it will protect your websites from attacks without interfering with legitimate traffic or slowing down your server. In addition, it will ease the work of your server administrators by handling a number of security tasks.
What Is Imunify360?
Imunify360 is a comprehensive solution for securing Linux web hosting Melbourne servers that uses several layers of security technologies in order to secure a server. Instead of relying on one protection tool, Imunify360 analyses the traffic, website files, server requests, and behaviour of web applications in order to detect any suspicious activity.
It unites a smart firewall, WAF, malware scanning, intrusion detection and prevention, exploit protection, reputation management, and malware cleaning in one package. Since these technologies exchange threat information with each other, their response time is faster than that of standalone solutions.
One more significant advantage is that of automation. The platform updates its security intelligence automatically based on the information gathered from all hosting environments being protected. In case new kinds of threats appear, the system automatically enhances its level of protection without having to set security rules manually. That helps to save time and enhance the overall resilience of servers.
For hosting providers that have hundreds or even thousands of websites to manage, it means a lot in terms of administration and protection.
Built for hosting servers
Imunify360 was not created for home or business PCs. Instead, it was developed to protect Linux web hosting servers with several websites in one operating environment.
There are specific features that make the protection of such servers challenging. In case one of the websites gets compromised, hackers try to spread malware, take too many resources and exploit other accounts.
The software is directly compatible with popular hosting control panels such as cPanel, Plesk, and DirectAdmin. Thus, security can be maintained using interfaces that hosting companies are accustomed to using daily. In addition, Imunify360 can run under the CloudLinux OS and other popular Linux operating systems used in professional hosting.
Due to the fact that Imunify360 works specifically with hosting architecture, the product ensures a high level of protection and efficient operation of servers.
Security does not involve any additional management overhead and does not affect hosting efficiency.
How Imunify360 Protects Your Hosting Server
Firewall + Threat Intelligence
Every connection attempting to access the hosting server poses a risk to the security of the system. Imunify360 addresses this problem with its intelligent firewall, which serves as the primary defense mechanism of the server.
Unlike conventional firewalls that rely mainly on manually set rules, Imunify360’s protection of Imunify360 is constantly updated according to global threat intelligence gathered about malicious IP addresses, botnets, and other attacks. The reputation information is acquired from millions of websites and servers all around the world that are currently being protected by the platform.
When traffic begins to enter the server, the firewall analyzes all connections before granting them access. Suspicious connections and activities, including brute force attacks, connection overloading, port scans, or any other malicious network traffic, are detected by the firewall.
In case of a confirmed threat, the firewall automatically blocks it without requiring the assistance of an administrator. Since the threat intelligence is constantly updated, the protection provided by the firewall is also constantly changing.
Web Application Firewall (WAF)
A number of successful attacks aim at web applications rather than the underlying operating system. An attacker may exploit vulnerabilities of a plugin or a content management system, insecure scripts or poorly coded applications to launch their attack. The Imunify360 WAF can help you cover such risks.
This technology checks each incoming HTTP/HTTPS request before it gets to the hosted application. Instead of letting all the incoming data flow straight to your website, it tests each of these requests against constantly renewed security rules meant to detect malicious activity.
When a particular request is found to match one of the known attack patterns, the WAF blocks it instantly. This way, it prevents attacks like SQL injection, cross-site scripting (XSS), remote code execution attempts, directory traversal and others before they get any chance to interact with the website.
The second important feature of a WAF is virtual patching. With virtual patching, the WAF protects the application from exploitation attempts before the patch has been released.
Malware Scanning + Auto Cleanup
Despite high-level prevention measures, malware can occasionally get into the hosting server either due to hacked credentials or out-of-date software and applications. Fast detection of infected files is critical, as malware can not only steal confidential data but also redirect visitors or distribute spam.
The continuous scanning of server files is performed by Imunify360 by both scanning based on signatures and analyzing the behavior of the file. The system does not scan the server only for the signatures of the already known malware, but it also monitors any suspicious activity of the file that may signal the emergence of the threat.
The administrators are provided with information regarding the infected files and their location. Depending on the server settings, the automated cleaning of the detected infection and keeping legitimate web content intact is performed. Continuous background scanning helps ensure that any newly uploaded and modified files are scanned.
Proactive Defense Against Zero-Day Attacks
Zero-day vulnerabilities represent one of the toughest challenges when it comes to security since they are exploited even before the developers come up with appropriate patches. Traditional security solutions rely on the detection of already discovered signatures of malware, which makes these security threats even harder to catch.
The problem is overcome by using Imunify360’s Proactive Defense technology. This solution does not rely on the identification of malware, but tracks the behavior of PHP scripts when they are running. If a certain suspicious behavior coincides with that of known attack vectors, the process gets blocked by Imunify360 prior to any harmful actions.
IDS/IPS + Kernel Patching
Server security needs constant monitoring and quick vulnerability management as well. The solution provided by Imunify360 involves using Intrusion Detection and Prevention along with live kernel patching.
The Intrusion Detection System included in this software checks the server activity to identify any signs of intrusion into the system. Then, the Intrusion Prevention System blocks or limits the threat in order to prevent its impact on the server.
Also, Imunify360 uses KernelCare Enterprise technology that helps to perform Linux kernel security patches without needing to restart the server. Thus, businesses can keep their websites up and running while making sure of the security of the servers. As a result, they provide better server security without affecting the work of their hosted websites.
