As we are moving into the future, the complexity of DDoS attacks are growing in complexity as well as volume. They have grown to such an extent that they now portray themselves as one of the leading threats for any organization. Nowadays, most corporate firms have standardized internal departments to battle and mitigate this looming threat; however, those who are relying on service providers and enterprise are compelled to do their research, if their service provider has enough knowledge to overthrow the modern day DDoS threats. In order to protect the infrastructure, there are burdens of cost associated which utilize a large amount of infrastructure resources.
Since, traditional DDoS Protection services use rate limiters and manual signatures to keep DDoS attacks out of the infrastructure, both processes can only be effective in mitigating the DDoS attack permanently if the infrastructure is not open to high false positives. Manual signatures can do keep most false positives out of the network; however, they are yet dependent on the attack taking place and their generation process is a bit too long which can either take hours or even, in some cases, days. Modern day DDoS attacks are automated and can cripple your system at a pace of 20 seconds per attack.
This attack ratio mitigates the purpose of Manual signature and hence, the overall protection strategy.
How Effective DDoS Protection Can Help Secure Infrastructures?
DDoS protections are now being automated which is ultimately making them effective for the world. A strong DDoS protection service involves sophisticated machine-learning algorithms that are based on negative and positive models. They do support rate limiting as well resolving thousand of queries per day.
Machine Learning Algorithm to Protect Against DDoS Attacks
One of the best ways to mitigate a DDoS attack is to enable the automatic detection of the incoming attack traffic and then dissolve it at the source of generation. With machine learning, bots can enable themselves to automatically detect, analyze and mitigate such DDoS attacks and then additionally learn about the source of occurence to permanently block it.
This is how machine learning is leveraging different mitigation schemes to dissolve the attack permanently:
- By creating redundant profiles of normal legitimate traffic and run tests to detect anomalies in the network from normal traffic behavior.
- Characterizing the attack traffic to create an initial signature.
- Automatically optimize the initial signature using a closed-feedback mechanism.
- Automatically identify when the attack has ended and then stop the mitigation process.
If incoming attacks are coming from random sources from a botnet network, the positive protection model creates a signature logic which automatically drop all traffic coming from unreliable source only allowing positive traffic to enter into the site network.
How Machine Algorithms Will Create Zero-Time to Mitigation
Although, negative and positive machine learning algorithms are handful to mitigate incoming attacks with minimum false positives; however, in this case the automated signature generation process only last for a few seconds until another signature is generated. If attackers are much sophisticated in breaching the defense by making use of this short-window where a signature is missing for some time, the attacker can unleash a high volume, short-lived burst attack into the infrastructure.
In such cases where digital signatures can become ineffective, a previous layer of security dependent on rate limiters can help fend off unwanted traffic from the network. Rate limiters surround the external circumference of the security layer where it applies a limitation on the attack traffic to a rate that keeps the network infrastructure protected from going into down-time. In short, it stops unwanted traffic in order to save the dedicated servers from permanently crashing until a next signature is generated.
