2020 is ending and if we see in a DDoS view it’s retrospective. This year a game changer iin history where record breaking Attacks have been in sight… Financial .. Medical departments have seen a large volume of attacks. This rise in both attack size and sophistication has naturally brought about an increase in interest in DDoS protection solutions,

As businesses begin to quickly realize that DDoS protection can come in a variety of formats, and they must consider which deployment type is best for them: On-Demand cloud service, Always-On cloud service, on-prem appliance, or Hybrid protection

Different Deployment Options are Better for Different Use Cases

There is no such thing as the “best” type of DDoS protection. Rather, different deployment options have different merits and drawbacks, and as a result, are best-suited for different business use cases.Thus, is becomes a question not of “what is the ‘best’ type of DDoS protection?”, but of “which deployment options are best suited for your needs?”

Hardware Appliance: Advanced Functionality, but Limited Capacity

DDoS protection relied on hardware appliances deployed at the customer’s data centers. Hardware appliances frequently provided advanced protection, low latency, and granular control by network admins.

But its capacity was constrained by limits of the hardware appliance, or the traffic pipe leading into it. These limits made hardware appliances susceptible to large volumetric attacks which saturated the organization’s traffic pipe. An additional overhead on upfront cost .

Standalone hardware appliances are most suited today either for large organizations or service providers who are creating their own mitigation scrubbing centers or Organisation restricted from using cloud services.

On-Demand Cloud Service: Massive Capacity, When needed

Due to the capacity constraints of hardware appliances, many organizations began looking to cloud-based scrubbing services for a solution. Compared to standalone hardware appliances, cloud scrubbing services offer bombarded capacity measured in TB’s.

The first type of cloud-based DDoS protection is the On-demand service – as its name implies – is activated only once an attack is detected. During peacetime, on a routine basis, traffic flows directly to the customer’s network. Only once an attack is detected is traffic diverted to the cloud scrubbing center, where traffic is ‘scrubbed’ for malicious traffic and only ‘clean’ traffic is sent back to the customer location.

The advantages of the on-demand approach is that since traffic flows on a routine basis directly to the customer location, it does not add any latency during peacetime. On-demand services usually have little operational overhead and do not require day-to-day management or maintenance. In addition, they are usually the cheaper than other deployment types.

The drawbacks of the on-demand cloud service, however, is that attack detection is usually based only on volumetric detection and that traffic diversion – once it takes place – requires a certain window of time until diversion is complete, and the customer will remain vulnerable during this ‘diversion gap’. Best suited for non mission critical organization that gets attacked infrequently

Always-on Cloud Service: Continous Protection,Added Latency

An alternative to on-demand protection is an always-on cloud service. Under the always-on model, traffic is routed on a constant basis through a cloud scrubbing center, where it is inspected for DDoS traffic.

The advantages of the always-on model is that it eliminates the need for diversion when there is an attack and provides 24/7 protection. It also allows for more granular detection of attacks, including detection of non-volumetric attacks. It’s comparitively high, expensive and suits for organization that comes under frequent attacks

Hybrid Protection: Best in Best of Class

The hybrid combination model combines both an on-premise appliance together with a cloud service. This allows protected organizations to enjoy both the advanced capabilities of hardware appliances, along with the massive capacity of a cloud service. As a result, customers can defend against both large and sophisticated attacks, and level multi-layered protection so that if an attack is able to get around the cloud defenses, it will be mitigated by the appliance. A hybrid solution is usually more expensive, since it combines both an appliance and a cloud service requires for most mission critical services

There is No “Best” Solution; All Depends on Your Needs

In the end nothing is best in the market available readily, need to be tailored as per the requirement , budget, threat landscape, attack vectorx
