A Distributed Denial of Service (DDoS) attack is when a web service or application receives an overwhelming amount of traffic that it cannot respond. The most common way that this is achieved is through the coordinated use of “bots” – devices or endpoints that have had malware installed on them, allowing an attacker to control them. 

A DDoS attack will cause a site to crash and can affect both front end and backend communication. This means that as well as customers being unable to reach your site, you might be prevented from communicating internally to resolve the issue. This type of attack is ever evolving and becoming more complex. To respond to this sophisticated threat, organizations need to implement an effective DDoS protection solution.

It can be difficult to understand how the different solutions work, and what you need – with cloud-based, on-premises, and hybrid solutions that cover different communication layers making the choice more complicated. 

In this article we’ll explore the top DDoS protection solutions, focusing on those that work at the network, transport, and application layers. Common features include real-time threat detection, reporting, analytics, and multi-layer protection. For each solution, we’ll give some background information, highlight key features, and suggest the type of customer that they’re most suitable for.

Akamai’s cloud-based web application firewall (WAF) Kona Site Defender stops threats through configurable firewall layers, backed by Akamai Threat Research. The system benefits from both artificial and human intelligence with automated processes, custom policies and responses to malicious traffic to adapt to the scale of your business helping boost your business’ security posture. The application firewall also features automatic API discovery, self-tuning, and WAF updates that can be manually implemented or configured automatically. Akamai have also made SIEM integration seamless too, allowing the platform to run alongside pre-existing on-premises and cloud-based SIEM applications.

Edge DNS is Akamai’s cloud-based DNS solution with a globally distributed anycast network foundation, offering non-stop DNS availability, increased responsiveness, and DDoS protection. Implementation can come as a primary or secondary DNS service, helping to support existing DNS infrastructure, or even replace it. Edge DNS provides a 100% uptime service level agreement (SLA), and with thousands of DNS servers worldwide, connections to your website and application servers can be reliable. Edge DNS can withstand the sufficient DDoS attacks through absorbing the traffic while responding to legitimate user requests, so users can still access your domain throughout an attack uncompromised.

Prolexic Routed provides comprehensive protection against DDoS attack of all shapes and sizes, from high bandwidth sustained attacks, to vector application attacks. The platform utilizes Border Gateway Protocol (BGP) to re-route traffic through Akamai’s scrubbing centers (8tbps capacity) – once there, mitigation controls disband all abnormal traffic immediately and the Akamai SOCC team analyze the remaining traffic for malicious threats. From here, only clean traffic is re-routed back to your domain.

AWS Logo

AWS Shield

Amazon Web Service’s (AWSs) answer to DDoS protection comes in the form of AWS Shield, a managed platform that provides comprehensive defense against network, transport and application-layer attacks. The service provides two tiers of support for customers of AWS; Standard and Advanced.

The standard DDoS package provides protection against network and transport layer attacks, and can be combined with Amazon Cloudfront and Amazon Route 53 for a fully comprehensive DDoS solution. One of the key features of this solution is the seamless integrations available. Due to its exclusivity with AWS, Shield is already active for existing AWS customers, with add-ons accessible through the management console or via API. The service is always-on, monitoring traffic flow into AWS services using filters that analyze traffic signatures and anomaly detectors. There are also automated mitigation systems, such as deterministic packet filtering and priority-based traffic shaping, which help nullify basic network layer attacks. All of these features are applied in line with the existing AWS services, which means there’s no impact on latency.

Shield Advanced builds on the standard package by enabling admins to implement custom firewall policies through the web-application firewall (WAF) to defend against business-specific threats. The firewall can also be configured to run proactive rules such as rate-base blocks to nullify an early-stage DDoS attack. The system can be tailored to either act or react to incoming threats, so it can outright block traffic and hunt for threats, or deal with them as they hit. Its health-based detection can be configured through the API to prioritize the response to unhealthy/vulnerable applications first. Advanced users can also utilize the Shield Response Team (SRT), whereby the team can contact your organization in the event of a DDoS attack, helping to identify the threat and stopping it too. Centralized management is also a key feature of Shield Advanced, where admins can manage both Shield and the WAF across the organization in one place, quickly and efficiently implementing universal policies and defenses.

NexusGuard Logo

Nexusguard MX7000 Mitigation Platform

Nexusguard’s MX7000 Mitigation Platform is a “cloud-in-a-box” DDoS mitigation service for cloud service providers. The platform defends against network, transport and application-layer attacks by analyzing traffic, detecting and nullifying threats in real-time. When an attack threatens to overload the local capacity, traffic can be re-directed to Nexusguard’s scrubbing centers, which cleanse the malicious traffic and feed the genuine traffic back to the site. Nexusguard’s detection technology utilizes anomaly detection, black/whitelisting, deep packet inspection, session timeouts, rate limiting, and caching and load balancing. The platform continuously monitors the incoming IP and application requests, which helps plot behavioral patterns for the system to determine whether an anomaly or an attack is about to take place. This behavioral analysis also creates a baseline whereby the system can recommend threshold values to stop attacks more effectively. The built-in web application firewall (WAF) also provides cover against application-layer attacks in depth.

The mitigation process features extensive hi-speed, adaptive application-level filtering with flexible content filters too. The hi-speed border filters out fraudulent IP addresses and infected hosts, followed by protocol verification that utilizes challenge-response algorithms such as TCP SYN cookie and TCP SYN authentication, which helps differentiate malicious and legitimate traffic. The adaptive filters use  AI and machine learning technologies to understand your company’s baselines, against which they can detect anomalies. Once the traffic reaches the application layer, filters engage specific HTTP policies to guarantee genuine HTTP transactions, whilst also limiting the volume of connection and/or requests to specific objects. The flexible content utilizes the baseline to analyze traffic for anomalies and HTTP flood attacks through adaptive content filters to provide fast counters to attacks. The WAF eases customer management, protects web applications from attacks, safeguards sensitive information, and controls access of the applications through traffic analysis, aiding PCI-compliance.

FAQs

How To Protect Your Network From Becoming Bots?

While this top 10 article has focused on solutions that prevent your site from falling victim to a DDoS attack, it is worth spending a moment to consider how we can prevent bots in the first place. As bots are a form of malware, preventing your system from being infested will ensure your systems are not used in an attack.

Securing your perimeter is essential if you want to identify and block threats from accessing your systems. You can achieve this through implementing a firewall or endpoint detection and response (EDR) solution.

A firewall acts as a permitter and scans all content that attempts to gain access to your network. It can block known threats or conduct sandboxing and quarantining for unknown content that has the potential to be malicious. Firewalls will prevent the vast majority of threats from being installed on your devices, thereby offering you an essential level of protection.

Endpoint detection and response (EDR) solutions will proactively monitor requests and usage at each of your endpoints. If any malicious content is identified, the EDR will work to block the threat using predefined playbooks, as well as AI and ML capabilities. The EDR can carry out threat hunting to trace malware through your system and identify any residual code.
