DDoS attacks have been on the rise not only in numbers but also in sophistication, making them a top threat to any business or organization of all sizes. Such malicious attacks can overwhelm the network or website and make it unavailable to real users; which could lead to huge financial and reputational damage. Hence, it becomes important to enforce robust protection mechanisms against the growing threats of DDoS.
Herein, we walk you through the 13 best DDoS protection software in the market today. These solutions are equipped with advanced features and technologies to handle the prediction, mitigation, and prevention of DDoS attacks. Before we look through the list, how can application layer DDoS attacks be detected?
What is DDoS?
A Distributed Denial of Service attack is a malicious attempt that uproots the normal operating manner followed by the targeted server, service, or network, by bombarding it with excess internet traffic emanating from various sources.
This excess internet traffic utilizes all the spaces available within the targeted area, rendering it unable to respond to other requests and hence making the service unavailable to genuine users.
There are the following types of DDoS attacks:
- Volumetric attacks: These are those that swamp the victim with high traffic volume, which utilizes all free bandwidth available.
- Protocol attacks: These attacks exploit weaknesses in network protocols, thereby draining server resources.
- Application layer attacks: These are so named because they target specific applications or services. They “mirror” or “emulate” normal user behavior in application-layer DDoS attacks so security controls used will not tag it as an attack traffic.
How DDoS Protection Software Works
A DDoS protection software works through a multilayer set of mechanisms for the detection, mitigation, and prevention of DDoS attacks. Here is a breakout of how most of these systems work:
1. Traffic monitoring and analysis
The first line of DDoS defense involves the continuous monitoring of incoming network traffic. Compound algorithms inspect traffic patterns for irregularities, potentially indicative of an attack, including:
- Parsing packet headers and payload data
- Observing traffic volume and rate
- Analysis of source IP address and geolocation data
- Identification of abnormal traffic patterns or spikes
2. Detection of Attack
If a detected anomaly, the software uses the following to determine whether it is a real DDoS attack:
- Signature-based detection compares the pattern of traffic against the already-known pattern of a DDoS attack.
- Behavioral analysis identifies different traffic that does not meet the preset baselines.
- Machine learning algorithms learn new vectors of attack and threats that are evolving.
- Detecting events of interest by the application of rule-based systems.
After the attack is confirmed, the protection software initiates filtering and scrubbing of the traffic:
3. Traffic Filtering and Scrubbing
- Blacklisting: Blocking the traffic from known sources of the malicious IP addresses
- Whitelisting Blocking the network such that it would only accept traffic to or from known trusted sources
- Rate limiting: Restriction applied on the number of requests per second from a single source
- Protocol validation: Noncompliant traffic is filtered, that does not follow the proper network protocols in use
- Deep packet inspection: the inspection of packet content to identify and block malicious payloads
4. Traffic Rerouting
Most DDoS protection solutions will implement some approach to traffic rerouting. These include the following:
- Anycast network: the sending of traffic to many data centers worldwide; this spreads the traffic volume to take on the size of an attack
- Scrubbing centers: rerouting suspicious traffic and cleaning it in centers established especially for this, and then finally forwarding it to the source server
5. Real-time Mitigation
The DDoS Protection Software changes its mitigation tactics in real-time as the attack progresses.
- Dynamic rule creation: generate new rules for filtering about the characteristics of the attack
- Adaptive thresholds: modifies the traffic limits based on the current network conditions
- Challenge-response: Trigger CAPTCHAs or JavaScript challenges for bot traffic filtering
6. Load Balancing and Scaling
In the event of an attack
- Distribute the traffic across numerous servers to avoid congestion
- Automatically adjust the resources to cater to the volume of traffic
7. Reporting and Analytics
A great DDoS protection software has to generate the smallest detail in attacks. This encompasses a real-time attack visualization and delivers in-detail logs and reports for the attacks that occur. It should also provide a post-attack analysis to allow organizations to be on guard beforehand.
Key Features in a DDoS Protection Software
Features to check in a DDoS attack protection solution include:
1. Multi-Layer Protection: Volumetric, Protocol, and Application Layer Protection.
2. Global Network: For its extended global network of scrubbing centers and points of presence (PoPs); it needs to distribute and mitigate traffic efficiently.
3. Machine Learning: Powerful AI and machine learning algorithms enhance detection accuracy and evolve with new attack vectors.
4. Custom Policies: The rules of protection should be customized by your application and infrastructure requirements.
5. Real-time Monitoring and Alerts: Immediate notifications with detailed attack analytics allow fast response and planning.
6. API Integration: Easy integration to any safety infrastructure and tools for simplified operations.
7. Scalability: The solution should be able to take varying traffic volumes and adapt to your growing business needs.
