I. Experienced my self with DDoS Attack

Recently, my website has experienced a DDOS attack for 5 days. I use Cloudflare to encrypt my site, but they send A mass of request to my website. It’s about 27 million requests per day from these countries: Indonesia, Philippines, Brazils, Italy, Vietnam, India and some other countries that didn’t show on Cloudflare analyze because of a free account.

To prevent a DDoS attack, we should know what it is.

In computing, a denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. (wikipedia)

II. How to prevent DDOS Attacks with Cloudflare

Now, we can have an overview of DDoS, about what it’s. Shortly, when you checked and see a lot of request to your website at the same time, you should prepare for an incoming attack by following these steps.

3, Under Analytics Tab, go to the traffic analytics section.

You checked and see if top countries and the request. You will know the traffic come from these countries, that could be attackers.

4, Go to the Firewall Tab, next to Firewall event,

To check the record of traffic, and where the traffic go to, if there are any suspicious actions or URLs, you can block it in access rule ( over firewall event section)

5, More action depends on Your Cloudflare’s account type.

Now if you have a premium account in Cloudflare you can enable web application rule and some rule to stop DDoS attack or source of attack’s traffic.

6, Nothing you can do except for move to VPS server

Tell me what is a browse for security?

Tor Browse | Secure your activity at home
For a security browser We can use Tor Browser. 

I know someone use it for deep web, and black market. Then if they can do it, you can use it for security. But sure that you should be careful, though.
According to Tor Hacker Group, they have explained this security browse:

Tor uses 3 hops, but each of these hops is used by multiple users AT THE SAME TIME. This is very important. Each node has SEVERAL incoming and several outgoing connections. Every f*cking minute.
So if you trace somebody’s way IN to the node, you should then check EVERY TRACE OUT, means EVERY outgoing connection. Because you don’t know which exactly connection was used by your suspect.
This means, that on step 2 you will have to check MANY Tor Nodes without a clear assurance what exactly you are looking for. And every of that Nodes ALSO HAS MANY OUTGOING CONNECTIONS. Which leads as to MANY * MANY suspicious nodes on step 3.
And after step 3 you will have MANY * MANY * MANY possible routes, and only one of them is sought-for. It is virtually impossible to trace UNLESS YOU CONTROL ALL THREE NODES IN A CHAIN.

So be calm, things are not THAT bad.

  • Advantage: average speed, average privacy
  • Possible disadvantage: proxy usage fact is presented
  • General purpose: most suitable for 99% of tasks

Elite proxy

This security proxy only sends REMOTE_ADDR header, then they will not sho you are using a proxy server and consider your IP address as a regular user without using any suspicious method.

  • Advantage: high privacy, proxy usage fact is hidden
  • Disadvantage: low speed
  • Particular purpose: just very few cases when the fact of proxy usage should be hidden
