Cyberattacks are not limited to large corporations. Small businesses, online sellers, consultants, contractors, service providers, and growing brands can also become targets — especially when their websites, customer portals, payment systems, or cloud tools are connected to the internet.
One of the most disruptive types of cyberattacks is a Distributed Denial-of-Service attack, commonly called a DDoS attack. These attacks are designed to overwhelm a website, server, application, or network so real customers and users cannot access it.
According to CISA, organizations should understand the DDoS landscape, prepare response plans, and know how different DDoS attacks can affect operations. Cloudflare defines a DDoS attack as an attempt to disrupt normal traffic by overwhelming a target with internet traffic from multiple compromised systems.

What Is a DDoS Attack?
A DDoS attack happens when attackers use many devices or systems to send large amounts of traffic or requests to a target. The goal is to exhaust the target’s resources so the website, server, app, or network becomes slow, unstable, or completely unavailable.
Many DDoS attacks are powered by botnets. A botnet is a group of infected computers, servers, routers, cameras, or internet-connected devices that attackers control remotely. These compromised devices send traffic toward the victim at the same time, making the attack harder to block.
Why DDoS Attacks Matter to Small Businesses
If your website or online system goes down, your business can lose sales, leads, appointments, customer trust, and operational time. For companies that rely on e-commerce, online booking, cloud tools, client portals, digital payments, or lead forms, downtime can directly affect revenue.
The 3 Common Types of DDoS Attacks
1. Volumetric Attacks
These attacks flood the target with massive amounts of traffic to consume bandwidth and overwhelm the network connection. The result can be slow loading, outages, or complete service disruption.
2. Protocol Attacks
These attacks exploit weaknesses in network protocols and connection-handling systems. They can exhaust firewalls, routers, load balancers, or server resources.
3. Application Layer Attacks
These attacks target the website or application itself. They may look like normal web requests, which can make them harder to detect. Cloudflare notes that application-layer attacks can consume both server and network resources.
Warning Signs of a Possible DDoS Attack
- Your website suddenly becomes very slow.
- Customers report that pages are not loading.
- Your server or hosting dashboard shows unusual traffic spikes.
- Traffic appears to come from strange locations or repeated sources.
- Your forms, checkout pages, portals, or login pages stop responding.
- Your hosting provider alerts you to abnormal traffic patterns.
How to Protect Your Business from DDoS Attacks
1. Use a Web Application Firewall
A web application firewall, or WAF, helps filter suspicious traffic before it reaches your website or application. This is especially important for login pages, contact forms, payment pages, and customer portals.
2. Use a DDoS Protection Provider
Providers such as Cloudflare, AWS Shield, Akamai, and similar security platforms can help detect, absorb, and mitigate attack traffic. AWS states that Shield Standard provides automatic protection for AWS customers against common network and transport-layer DDoS attacks.
3. Monitor Website and Network Traffic
Monitoring helps identify abnormal traffic patterns early. Business owners should review hosting alerts, server logs, analytics spikes, and uptime notifications.
4. Use a Content Delivery Network
A CDN helps distribute website traffic across multiple locations. This can reduce the pressure on your main server and make it harder for attackers to overwhelm one point of failure.
5. Create an Incident Response Plan
Your team should know who to contact if the website goes down, including your hosting provider, IT support, security vendor, domain provider, and payment processor.
6. Train Your Team
DDoS protection is part of a larger cybersecurity strategy. Employees and contractors should understand phishing, password safety, MFA, account protection, and how to report suspicious activity.
