How to protect your site from DDoS attack[Prevention]

Quantazone blog: How to protect your site from DDoS attack
What is DDoS?

distributed denial-of-service (DDoS) attack is an attack in which multiple compromised computer systems attack a target. Generally, servers, websites or other network resources are attacked. Which causes a denial of service for users of the targeted resource. The flood of incoming messages, connection requests or malformed packets to the target system forces it to slow down or even crash and shut down. This results in a denial of service to legitimate users or systems.


What’s the difference between DoS and DDoS?

A Denial of Service (DoS) attack differs from a DDoS attack. The DoS attack typically uses one computer and one Internet connection to flood a targeted system or resource. The DDoS attack uses multiple computers and Internet connections to flood the targeted resource. DDoS attacks are often global attacks.

Is really DDoS attack a matter of concern?

In recent years, DDoS attack has become a matter of concern even for Tech Giants. On February 28, 2018, GitHub(a popular developer platform) was hit with sudden traffic that clocked in at 1.35 terabits per second. The amount of traffic is not only massive, but it’s also record-breaking. According to GitHub, they traced the traffic back to “over a thousand different autonomous systems (ASNs) across tens of thousands of unique endpoints.”

Not only tech giants, but attackers haven’t left even broadcasting companies. On the last day of 2015, a group called “New World Hacking” launched a 600 Gbps attack on the servers of BBC. They used their own BangStresser application tool for this attack.

The frequency of DDoS attacks is increasing day by day. We have observed it attacks sized 100Gbps and higher increased by 967% in Q1 2019 compared to Q1 2018; the report found. We are still in Q1 of 2020, it always said that prevention is better than cure save your site from getting into the list of DDoS attacks in Q1 2020 with us. With a current value of $2.4 billion in 2019, one research firm estimates the DDoS protection and mitigation market will nearly double to $4.7 billion by 2024.

Are you already under attack [Symptoms?]

These signs can identify DDoS attacks:

  • Website latency When the website is unavailable without no deployment problem from your end, that might be some intruder trying to interfere with your servers.
  • Access limitations When it takes a long time to access the website and unable to load then it’s a matter of concern.
  • Internet connection issues if you are a target.
Arm yourself against DDoS [Prevention]

Till now we told you what is DDoS, How it looks now it’s our responsibility to tell you how to safeguard yourself from it. Following are some precautionary measures you can take-

  • Increase Internet Bandwidth and Server Capacity The main reason your website can crash or go offline after a DDoS attack is if it doesn’t handle the volume of traffic sent by the attacker. Buying additional bandwidth and enlarging your website’s server capacity are excellent ways to reduce the impact of a DDoS attack.
  • Use Web Application Firewalls Using web application firewalls is a great way to protect larger enterprise-level applications. A firewall can detect and prevent attacks by monitoring unusual spikes in traffic and blocking them.
  • Content Delivery Network Using a CDN is another popular way people protect their websites from a distributed denial of service. Using a CDN means it hosts your website multiple IP addresses; so even if an attack succeeds on one of them, you still have a few backups that can keep your website running until you figure out what is going on.
  • Hire a DDoS Mitigation Service Another technique to prevent attacks is to hire a DDoS mitigation service. Their way of preventing attacks is to route all incoming traffic through a filter so that only genuine traffic hits your website or application.
  • Invest in Good Network Hardware Investing in high-quality network hardware can help you detect unexpected spikes in website traffic and even block them completely.

In my opinion, it’s better late than never to get your website protected from DDoS attacks. We are happy to help at Quantazone.
