Anyone with bad intentions can hire a hacking service for a targeted attack. Malware tools are accessible, easy to use, and effective. Not only large companies, but also cybercriminals look for vulnerable victims of any size, including personal blogs, e-commerce stores, and small and medium-sized businesses and one of the attacks that are becoming more frequent are DDoS and that is why we will see that it must contain an anti-DDoS system to repel these.
One type of attack is particularly dangerous and increasingly common. It’s called a distributed denial of service attack, or DDoS for short.
This attack is clearly dedicated to… attack a set of compromised distributed systems (can be servers, home computers, Internet of Things devices, anything connected to the Internet) is used to overwhelm a target system with a flood of requests, to the point where the attacked system becomes saturated enough to refuse to work.
For these there are several effective anti-DDoS solutions which must deal with some tasks like: detection, Detour, analysis, etc.
▸Detection
Detection means identifying deviations in traffic flow that could be predicting a DDoS assault. An effective anti-DDoS solution should be able to recognize the attack as soon as possible, avoiding false positives.
▸Detour
Divert traffic, either to discard it or to filter it. By filtering, we want to remove DDoS traffic and identify it as malicious. An effective anti-DDoS solution will do this without affecting the experience of its legitimate users.
▸Analysis
Analytics is the review of traffic logs to gather information about attacks, both to identify the attacker and to improve future detection activities.
When you need to compare anti-DDoS solutions, network capacity is an important factor to consider. It is measured in Gbps (gigabits per second) or Tbps (terabits per second) and indicates how much attack intensity the protection can support.
Other important measures of service level are delivery rates and mitigation time. The forwarding rate represents the capacity of the solution to process data packets and is measured in millions of packets per second (Mpps). Attacks commonly reach 300-500 Gbps, and some could scale up to 1 Tbps. The throughput of the anti-DDoS solution must exceed that to be effective.
