Your website is live, customers are placing orders, and everything seems to be running smoothly. Suddenly, traffic spikes, the server slows down, and within minutes, your website becomes inaccessible. While it may seem like a technical glitch, there’s a good chance you’re dealing with one of the most common cyber threats today: DDoS attacks.
In an increasingly connected digital landscape, strong cyber protection is essential for defending websites, applications, and online services against these disruptive attacks.
The frequency and scale of these attacks continue to rise. According to Cloudflare’s 2025 DDoS Threat Report, the company mitigated 21.3 million DDoS attacks in the first quarter of 2025 alone, highlighting how rapidly the threat landscape is evolving.
In this guide, we’ll explain how DDoS attacks work, the different attack techniques used by cybercriminals, and how Akamai helps businesses detect and mitigate these threats. We’ll also explore how ZNet, as an Akamai solution provider, helps organizations assess risks, deploy the right security solutions, and strengthen their overall cybersecurity posture.
What Is a DDoS Attack?
The DDoS attack full form is Distributed Denial-of-Service. DDoS is a cyberattack in which multiple compromised devices flood a target server, application, or network with an overwhelming amount of traffic. The goal isn’t to steal data but to exhaust system resources until legitimate users can no longer access the service.
Simply put, the DDoS attack means forcing an online service offline by overwhelming it with requests from multiple sources simultaneously. If you’d like a deeper understanding of how these attacks work and the strategies organizations use to defend against them, check out our guide on understanding DDoS attacks and countering them.
Imagine a retail store that can comfortably serve 100 customers at a time. Suddenly, thousands of fake visitors enter the store, blocking the entrance and preventing genuine customers from getting inside. The business hasn’t shut down, but it has effectively become unavailable to the people who matter. That’s exactly how a DDoS attack works in the digital world.
What makes these attacks particularly challenging is that the malicious traffic often comes from thousands or even millions of compromised devices spread across different locations. This makes distinguishing legitimate traffic from attacking traffic much more difficult.
DoS vs DDoS Attack: What’s the Difference?
Many people use these terms interchangeably, but they’re not the same.
A Denial-of-Service (DoS) attack originates from a single source. One machine attempt to overwhelm a target by sending excessive requests. While disruptive, these attacks are generally easier to identify and block because the traffic comes from a single location.
A Distributed Denial-of-Service (DDoS) attack, on the other hand, involves multiple compromised devices, often referred to as a botnet. These devices send requests simultaneously, creating a much larger volume of malicious traffic that’s far harder to stop.
|
DoS Attack |
DDoS Attack |
| Originates from one device | Originates from thousands of compromised devices |
| Easier to detect and block | Much harder to identify and mitigate |
| Limited attack volume | Extremely high traffic volume |
| Lower complexity | Highly coordinated and sophisticated |
For modern businesses, DDoS attacks pose a much greater risk because they can target websites, APIs, cloud applications, DNS services, and even entire network infrastructures.
What Are the Types of DDoS Attacks
Not all DDoS attacks follow the same pattern. Cybercriminals use different techniques depending on the target and their objective. The understanding of types of DDoS attacks helps organizations prepare the right defense strategy.
1. Volumetric Attacks
These are the most common DDoS attacks. The attacker attempts to consume all available bandwidth by flooding the network with massive amounts of traffic.
The objective is simple: saturate the internet connection so genuine users cannot access the service.
Examples include:
- UDP Flood
- ICMP Flood
- DNS Amplification
2. Protocol Attacks
Rather than targeting bandwidth, protocol attacks exploit weaknesses in networking protocols.
These attacks consume server resources or network infrastructure, such as firewalls and load balancers.
Common examples include:
- SYN Flood
- Ping of Death
- Smurf Attack
Even if bandwidth is available, these attacks can make applications unreachable.
3. Application Layer Attacks
Application-layer attacks are among the most sophisticated because they imitate legitimate user behavior.
Instead of overwhelming an entire network, attackers focus on specific applications or web pages.
A common example is an HTTP GET Flood, where attackers repeatedly request resource-intensive pages until the application becomes slow or unavailable.
Since the requests often appear genuine, these attacks are much harder to detect without advanced behavioral analysis.
A Real-World DDoS Attack Example
Imagine an online retailer preparing for its biggest annual sale. Marketing campaigns are live, customers are ready to shop, and website traffic is expected to increase.
Just minutes before the sale begins, millions of malicious requests start hitting the website from compromised devices across the globe.
The servers become overloaded.
Checkout pages stop responding.
Customers abandon their carts.
Revenue drops with every passing minute.
Meanwhile, the security team struggles to determine which traffic is legitimate and which is malicious.
This is a classic DDoS attack example. The attackers don’t need to breach the company’s systems or steal customer data. Simply making the website unavailable can result in lost sales, damaged reputation, and frustrated customers.
Industries such as eCommerce, banking, healthcare, gaming, and SaaS platforms are frequent targets because even a few minutes of downtime can have significant financial and operational consequences.
How Akamai Protects Businesses from DDoS Attacks
Detecting a DDoS attack is only half the battle. The real challenge is stopping malicious traffic without disrupting legitimate users. Traditional security solutions often struggle to handle today’s high-volume, multi-vector attacks, especially as businesses rely on cloud applications, APIs, and globally distributed users.
This is where Akamai DDoS Protection stands out.
Built on one of the world’s largest distributed edge platforms, Akamai operates more than 4,000 points of presence across over 130 countries, allowing it to inspect and mitigate attacks at the network edge before they reach your origin infrastructure.
Unlike traditional solutions that route traffic to centralized scrubbing centers, Akamai filters malicious requests closer to users, reducing latency while maintaining application performance.
Its globally distributed architecture helps organizations absorb large-scale attacks, minimize downtime, and ensure genuine users can continue accessing websites, applications, and APIs without interruption, even during sophisticated DDoS attacks.
Let’s look at how it works:
1. Stops Attacks Before They Reach Your Infrastructure
One of Akamai’s biggest strengths is its globally distributed edge network.
Rather than routing all traffic directly to your data center or cloud environment, Akamai inspects requests across thousands of edge servers worldwide. Suspicious traffic is identified and blocked before it reaches your origin servers.
Because attacks are mitigated at the edge, organizations reduce the pressure on their core infrastructure while legitimate traffic continues to flow normally.
2. Automatically Detects Suspicious Traffic
Modern DDoS attacks don’t always rely on massive traffic volumes. Some mimic genuine user behavior, making them much harder to identify.
Akamai continuously analyzes incoming traffic patterns to distinguish between legitimate visitors and malicious requests. Instead of relying only on predefined rules, it uses behavioral analysis to identify anomalies and respond in real time.
This enables businesses to detect attacks earlier and reduce false positives that could block genuine users.
3. Protects Against Multiple Types of DDoS Attacks
Cybercriminals rarely rely on a single attack method.
A single campaign may combine volumetric floods, protocol attacks, and application-layer attacks simultaneously.
Akamai is designed to defend against all major attack vectors, helping businesses maintain service availability even during complex, multi-layered attacks.
Instead of deploying separate security solutions for different attack types, businesses can rely on a unified platform that provides comprehensive protection across networks, applications, APIs, and digital services. This simplifies security management while improving overall resilience against evolving threats.
4. Maintains Website Performance During an Attack
Security shouldn’t come at the cost of user experience.
One of the biggest concerns during a DDoS attack is maintaining website availability for genuine customers.
Because Akamai distributes and inspects traffic across its globally distributed edge platform, legitimate requests continue reaching applications while malicious traffic is filtered before it affects business operations.
This approach allows organizations to maintain fast response times and a consistent customer experience, even when handling large-scale attacks.
5. Provides Real-Time Visibility
Responding quickly requires visibility.
Akamai gives security teams access to detailed dashboards and reporting that provide insights into attack size, traffic sources, targeted applications, and mitigation activity.
Security teams can monitor attack trends, identify recurring patterns, and make informed decisions based on real-time intelligence. These insights also help improve future security planning and reduce response times during subsequent incidents.
How to Prevent DDoS Attack
While no organization can completely eliminate the risk of a DDoS attack, there are several best practices that significantly reduce its impact.
-
Use a Trusted DDoS Mitigation Solution
You can’t rely solely on traditional firewalls as it isn’t enough against modern attacks.
A dedicated DDoS mitigation platform like Akamai provides continuous monitoring, intelligent traffic filtering, and automatic mitigation before attacks affect business operations.
Partner with an experienced Akamai solution provider like ZNet. It helps organizations deploy the platform correctly, assess existing security gaps, and optimize protection based on their infrastructure and business requirements.
-
Build a Layered Security Strategy
DDoS protection works best when combined with other cybersecurity controls.
Organizations should complement mitigation services with:
- Web Application Firewalls (WAF)
- API Security
- DNS Security
- Bot Management
- Threat Intelligence
- Continuous Monitoring
A layered approach improves resilience against multiple attack types.
-
Monitor Traffic Continuously
Unexpected spikes in traffic aren’t always good news.
Continuous monitoring helps security teams identify unusual behavior early and respond before attackers can cause significant disruption.
Proactive monitoring also helps identify abnormal traffic patterns that may indicate emerging threats, allowing organizations to take preventive action before an attack escalates.
-
Prepare an Incident Response Plan
Every business should have a documented response plan for cyber incidents.
Your plan should clearly define:
- Who responds first
- How attacks are verified
- Communication procedures
- Recovery steps
- Customer notification processes
Preparation often makes the difference between a minor disruption and a major outage.
-
Keep Infrastructure Updated
Outdated systems often become easier targets.
Regular software updates, security patches, and infrastructure reviews help reduce vulnerabilities that attackers may exploit alongside DDoS campaigns.
Security is an ongoing process, not a one-time implementation.
