If you own a website, you might have heard of the term “denial of service attack” or “DoS attack” for short. But what does it mean and how can it affect your website? In this blog post, we will explain what a DoS attack is, how it works, and how Rhino Hosting uses cPGuard to secure your website from such attacks.

 

What is a DoS Attack?

A DoS attack is a type of cyberattack that aims to make a website or a server unavailable to its intended users by disrupting its normal functioning. A DoS attacker typically sends a large number of requests or packets to the target website or server, overwhelming its capacity and preventing it from responding to legitimate requests. A DoS attack can cause slow performance, error messages, or complete shutdown of the website or server.

 

A DoS attack can be launched from a single computer or from multiple computers that are distributed across different locations. The latter is called a distributed denial of service attack or DDoS attack. A DDoS attack is more difficult to defend against because it involves many sources of traffic that can change dynamically.

 

Some of the common types of DoS attacks are:

SYN flood attack: This attack exploits a vulnerability in the TCP/IP protocol that initiates a connection between two devices. The attacker sends many SYN packets (requests to start a connection) to the target server with spoofed IP addresses, making the server wait for responses that never arrive. This consumes the server’s resources and prevents it from accepting new connections.

Ping flood attack: This attack uses the ICMP protocol that sends ping messages (requests to test the connectivity) between two devices. The attacker sends many ping messages to the target server with a large payload size, forcing the server to allocate resources to process them and reply. This consumes the server’s bandwidth and processing power and slows down its response time.

HTTP flood attack: This attack uses the HTTP protocol that transfers data between web browsers and web servers. The attacker sends many HTTP requests (such as GET or POST) to the target web server, requesting different pages or files. This consumes the web server’s resources and prevents it from serving legitimate requests.

How Rhino Hosting Protects Your Website with cPGuard

Rhino Hosting is a web hosting provider that offers reliable and secure hosting solutions for your website. One of the security features that Rhino Hosting provides is cPGuard, which is an ultimate security solution for your web applications. cPGuard is a software that contains anti-malware, proactive firewall, automatic file cleanup, and more. It can protect your website from various types of attacks, including DoS attacks.

 

Some of the benefits of using cPGuard are:

Optimized ModSecurity rules: ModSecurity is a web application firewall that filters and blocks malicious requests based on predefined rules. cPGuard provides optimized ModSecurity rules that cover common vulnerabilities such as SQL injection, XSS, file upload, web shell execution, and more.

CMS vulnerability fix: CMS stands for content management system, which is a software that allows you to create and manage your website content. Some of the popular CMS platforms are WordPress, Joomla, and Drupal. cPGuard can protect your CMS website from attacks and vulnerabilities by applying patches and fixes automatically.

Real-time intrusion protection: cPGuard monitors your website traffic and detects any suspicious or malicious activity in real-time. It can block attacks from known sources such as botnets, malware, hackers, etc. It can also prevent brute force attacks, which are attempts to guess your login credentials by trying different combinations.

Powerful scanner: cPGuard scans your website files regularly and removes any malware or infected files automatically. It also generates reports and alerts you of any issues or threats.

Advanced integration with CSF: CSF stands for Config Server Firewall, which is a software firewall that controls the network access to your server. cPGuard works seamlessly with CSF to automatically identify and block all network, application, and protocol layer attacks launched at your website.

With cPGuard, you can rest assured that your website is safe and secure from DoS attacks and other threats. Rhino Hosting offers cPGuard as part of its hosting plans at an affordable price.
