Prevention of DDOS Attacks
The DDoS attack will attempt to make an online service or website unavailable by flooding it with unwanted traffic from multiple computers. The attacker can then instruct and control the botnet, commanding it to flood a certain site with traffic: so much that its network ceases to work, taking the site offline
methods of doing DDoS attacks: UDP flood. ICMP (Ping) flood. SYN flood. Ping of Death. Slowloris. NTP Amplification. HTTP flood
The Dyn DDoS attack, which measured in at 1.2 Tbps and was considered the largest DDoS attack at the time, brought down much of the internet across the U.S. and Europe. Using the Mirai botnet, the attack targeted Dyn, a company that controls much of the domain name system (DNS) infrastructure of the internet.
There are several clues that indicate an ongoing DDoS attack is happening: An IP address makes x requests over y seconds. Your server responds with a 503 due to service outages. The TTL (time to live) on a ping request times out. If you use the same connection for internal software, employees notice slowness issues.
All Cloudflare plans offer unlimited and unmetered mitigation of distributed denial-of-service (DDoS) attacks, regardless of the size of the attack, at no extra cost. No penalty for spikes in the network traffic associated with a distributed attack
Six steps to prevent DDoS attacks Buy more bandwidth. Build redundancy into your infrastructure. Configure your network hardware against DDoS attacks. Deploy anti-DDoS hardware and software modules. Deploy a DDoS protection appliance. Protect your DNS servers.

ABSTRACT In the modern computer world, maintaining the information is very difficult. Some interrupts may occur on the local system (attack) or network based systems (network attack). Without security measures and controls in place, our data might be subjected to
How can I prevent DNS attacks? Audit your DNS zones. First things first. Keep your DNS servers up-to-date. Hide BIND version. Restrict Zone Transfers. Disable DNS recursion to prevent DNS poisoning attacks. Use isolated DNS servers. Use a DDOS mitigation provider. Two-Factor Authentication.
