From the point of view of business functions, cloud infrastructure provides scalable and cost-effective solutions. With this, it comes with attracting DDoS attacks. DDoS stands for Distributed Denial of Service. Even targeted attacks can block up infrastructures with so much traffic that they can, in principle, bring down any cloud environment. Consequently, proactive defense strategies lead a step ahead in asserting that cloud infrastructure is recognized against new threats. This article is based on securing cloud infrastructure from DDoS attacks with a proactive defense. Scroll down to learn more:

Understanding DDoS Attacks Against Cloud
DDoS attacks are categorized as attacks disrupting the availability of traffic being thrown onto the service from many unknown machines, usually referred to as a compromised device network. Such attacks pose a real threat to a diverse range of services, including all websites, applications, and APIs capable of bringing down a working website or application along with immense losses of value and credibility. As the world slowly becomes modernized to perform operations in the cloud, attacks affecting cloud infrastructure win the battle with weapons and the terrible power that access to an interconnected global infrastructure can earn in terms of currency.

Active Defense Strategies
- Leveraging DDoS Protection Services Provided by Cloud Providers
Most of the cloud service providers allow for the automatic detection of large-scale attacks and their mitigation. Google Cloud provides such services with DDoS protection through Cloud Armor, and AWS has services such as AWS Shield. The traffic analysis of these services consists of blocking the bad traffic and rate limiting to attempt detection of the abnormal traffic before it reaches the infrastructure. When the company enables and configures these protective means, it will essentially lessen the chances of successful attacks.
- Geofencing and Rate Limiting
This means that restrictions are placed on the number of requests that a user can submit to a service within a defined time limit. On the premise of threshold levels, companies can prevent an avalanche of traffic from overwhelming the system. Geofencing, or placing restrictions based primarily on geographical location, may also aid in blocking territory with no real users, thereby providing an additional means to restrict the attack surface.
- Multilayered Protection Strategy
As known, several defenses spread over many other layers of the architecture of the cloud. By applying the set of firewalls, IDS, and IPS all sitting on top of traditional DDoS protection, one can make very effective security layers. In such a scenario, the solution or simply the wrong solution would work against an attacker. He must deal with other layers which were never intended to work against him.

Conclusive Insights
Preferred DDoS attack defense for cloud security infrastructures needs to be proactive and multilayered, including cloud service provider protection, on-traffic analysis, and rate-limiting concerning a layered security approach. Overall, organizations using proactive countermeasures can significantly reduce the risk of DDoS attacks and keep cloud-based services reliable and available.
