What is a DDOS Attack & How to Protect Your Business Website?

DDoS is short for “Distributed Denial of Service,” which is what it does.

This service mitigation attack uses multiple servers or machines in different places to strike a single server or web application. Target is hit with a lot of traffic to stop its services. Most of the time, these attacks are done to get money from the attacker so that the website owner can pay to get his services back up and running. These attacks can last from hours up to days.

Types of DDOS Attacks: –

UDP Flood – DDoS attacks use a user diagram protocol to send many UDP packets to the target host on random ports. This keeps the host busy checking the following list.

The application is waiting on the given port.

Make sure that no app is listening. Send back a packet saying that the owner can’t be reached.

When the affected host gets a lot of requests, it will be busy answering them all, and other clients won’t be able to reach it.

Flood ICMP –

Internet Control Message Protocol, which network experts call “ping,” uses in DDoS attacks. This lets attackers send multiple “ping” requests to the hosts they want to attack and get the packets they sent back. Usually, ping requests uses to see if a host on a network is working or not. However, if more than one ping request sent to the same server or machine, that server or appliance will be down. ping -n, ping -t, and ping -I are all tools that can help in a DDoS attack.

SYN Flood –

In a typical link setup, the client sends a synchronization packet to the server, and the server sends back a sync-acknowledgment packet in the second step. When the host gets this message, it responds with an “ack” in the third step. But in a DDoS attack, the third step is skipped because the host either uses a fake IP address. Or methods that help the attacker not get the acknowledgments sent by the targeted host.

The Death Ping – In this type, attackers send a ping request with a large packet to the host they want to attack. This causes the victim’s computer to crash or stop. A suitably formatted IPV4 package, which includes an IP header, is defined and can’t be more significant than 65,535 bytes. If it gets bigger, it goes against the rules of the internet. So, the attacker sends small pieces of the bytes he wants. When the target host puts together the packet it got, it causes the host’s memory to overflow, which sometimes causes the target host to crash. So this ping is also known as the “ping of death.”

SlowLoris –SlowLoris is software that attacks the host server instead of the machines. It does this by making multiple HTTP requests and keeping sockets open to the server as long as possible. It waits until all of the sockets on the computer are busy.

Explanation of NTP – The network time protocol is the oldest protocol on the internet. It helps computers on the internet sync their clocks. During a DDoS attack, the spoofed IP address. Or the IP address of a victim is used to send repeated requests to the NTP Server.

HTTP Flood – The GET and POST methods send several HTTP requests to the target host in this technique. You can get standard, static content like images with a GET request. With a POST request, you can access resources created on the fly.

Zero-Day DDoS Attacks

This group is for all DDoS attempts that are unknown or new.

  • What to do about the DDoS attack
  • You can take many precautions, such as checking your network data and practicing DDoS attacks.
  • You can check your network by using Google Analytics to track any sudden increase in traffic. This will help you be ready for a DDoS attack when it happens.
  • Test run DDoS attacks uses to see if your system can handle a DDoS attack. The following free and open-source tools can be use for this.
  • The Ion Cannon in Low Orbit
  • Unicorn UDP
  • Putting up a firewall

Putting up a firewall makes it less likely that a DDoS attack will happen. A hardware firewall or a program firewall are also options.

Impact of DDoS attacks

DDoS attacks can have severe consequences for businesses and individuals alike.

Financial consequences: The downtime caused by a successful DDoS attack can result in significant financial losses for organizations, especially those reliant on online services for revenue generation. Loss of customer trust and potential legal liabilities further contribute to the financial impact.

Reputational damage: When a website or service is unavailable due to a DDoS attack, it reflects poorly on the organization’s reputation. Customers may lose trust in the company’s ability to provide reliable services, leading to long-term damage to the brand’s image.

Disruption of services: DDoS attacks can disrupt critical services, such as online banking, e-commerce platforms, or government websites, causing inconvenience and frustration for users. In some cases, they can even pose risks to public safety if essential services are affected.

Prevention and mitigation techniques

Organizations can employ various techniques to protect themselves from DDoS attacks and mitigate their impact.

Network and infrastructure protection: Implementing robust network security measures, such as firewalls, intrusion detection systems, and load balancers, can help defend against DDoS attacks. Additionally, optimizing network configurations and using content delivery networks (CDNs) can distribute traffic and reduce the impact of attacks.

Traffic filtering and rate limiting: Implementing traffic filtering mechanisms can help identify and block malicious traffic, reducing the impact of DDoS attacks. Rate limiting techniques can restrict the amount of traffic accepted from individual sources, making it harder for attackers to overwhelm the target.

Anomaly detection and traffic analysis: Using anomaly detection systems and traffic analysis tools can help identify abnormal patterns and traffic behavior, enabling early detection and proactive mitigation of DDoS attacks.

DDoS mitigation services: Leveraging the expertise of DDoS mitigation service providers can offer additional layers of protection. These services employ advanced techniques and infrastructure to detect and mitigate DDoS attacks in real-time, ensuring minimal disruption to services.

Install a security checker for malware.

Installing a malware security checker can also help check all data that comes into the system before it use. It also sends out a message when it finds something unclear.

Outsourcing – You can hire someone else to keep your website safe from DDoS attacks. You can also talk to your host about this and ask them to take down your website briefly and stop DDoS attacks. When you return online, you must use either Akamai, Cloudflare, Imperva Incapsula, DOSarrest, or another security tool.
