Or everything you wanted to know about DDoS attacks:

So what is DDoS attacks or the less known name – distributed denial of service.

A distributed denial of service (DDoS) attack is an attempt to make an online service unavailable by overwhelming it with traffic from multiple sources. They are often used to target websites or services that rely on a single IP address.
It’s is a known cyber attack matehood as I mentioned in my previous articles.

DDoS attacks are considered a serious threat in the cyber security of the Internet and have been increasing in frequency and sophistication in recent years. In October 2016, the United States Department of Homeland Security released a report warning that DDoS attacks are a “growing and morphing threat” to the country’s critical infrastructure.

There are two types of DDoS attacks:

1.Volume-based attacks:

These attacks use a large amount of traffic to overload the bandwidth of the victim’s network or server. The most common type of volume-based attack is a SYN flood, which uses the SYN flag in the TCP header to create a connection with the victim’s server without completing the three-way handshake.

2.Protocol-based attacks:

These attacks exploit vulnerabilities in the protocols that are used to communicate between devices on the Internet. The most common type of protocol-based attack is an ICMP flood, which uses the ICMP protocol to send large amounts of data to the victim’s machine.

DDoS attacks can be very difficult to defend against because they can come from anywhere in the world and can be very difficult to trace. The best defense against DDoS attacks is to have a reliable and robust network infrastructure in place.

There are a number of DDoS mitigation strategies that can be used to protect against cyber attacks and cyber crimes, including:

1.Rate limiting:

This is a technique that can be used to limit the amount of traffic that is allowed to reach a server. This can be effective at mitigating DDoS attacks, but it can also result in false positives that block legitimate traffic.

2.Blacklisting:

This technique can be used to block traffic from known-bad IP addresses. This can be effective at mitigating DDoS attacks, but it is also susceptible to false positives.

3.Whitelisting:

This is a technique that can be used to allow only traffic from known-good IP addresses. This can be effective at mitigating DDoS attacks, but it can be difficult to implement.

4.Geo-blocking:

This is a technique that can be used to block traffic from specific geographic regions. This can be effective at mitigating DDoS attacks, but it can also result in false positives that block legitimate traffic.

5.DNS filtering:

This is a technique that can be used to block traffic from specific DNS servers. This can be effective at mitigating DDoS attacks, but it can also result in false positives that block legitimate traffic.

6.BGP filtering:

This is a technique that can be used to block traffic from specific Autonomous Systems (ASes). This can be effective at mitigating DDoS attacks, but it can also result in false positives that block legitimate traffic.

7.Cloud-based DDoS protection:

This is a service that can be used to protect against DDoS attacks. It works by routing traffic through a network of servers that are designed to absorb attacks.

8.Hardware DDoS protection:

This is a service that can be used to protect against DDoS attacks. It works by using specially designed hardware to filter traffic and block malicious traffic.

9.Dedicated DDoS protection:

This is a service that can be used to protect against DDoS attacks. It works by providing a dedicated connection to a filtering appliance that is designed to block malicious traffic.

10.DDoS-as-a-Service:

This is a service that can be used to launch DDoS attacks. It is typically used by criminals to attack websites or services for financial gain or to disrupt operations.

In conclusion:

A distributed denial-of-service (DDoS) cyber attack is an attempt to make an online service unavailable. They are considered a serious threat to the security of the Internet. The best defense against DDoS attacks is to have a reliable and robust network infrastructure in place. Blacklisting can be effective at mitigating DDoS attacks, but it is susceptible to false positives. DNS filtering can be used to block traffic from specific DNS servers. Dedicated DDoS protection can provide a dedicated connection to a filtering appliance that is designed to block malicious traffic.
