By the Team at Krypto IT | Cybersecurity Experts Serving Houston SMBs

Imagine your small to medium-sized business (SMB) is suddenly hit with a massive, unexpected flood of customers—all trying to get through your front door at once. The phone lines jam, the website crashes, and your team can’t process any legitimate transactions.

In the digital world, this is known as a Distributed Denial of Service (DDoS) attack. It’s a devastating form of cyberattack that doesn’t aim to steal your data, but rather to paralyze your operations by flooding your network and servers with overwhelming amounts of fake traffic. For an SMB that relies on online sales, cloud applications, or a customer-facing website, a DDoS attack can cause crippling downtime and revenue loss.

At Krypto IT in Houston, we understand that survival during a flood requires preparation. This guide breaks down what a DDoS attack is and outlines the practical steps your SMB can take to build the digital defenses needed to stay afloat.

What is a DDoS Attack? (The Traffic Jam Analogy)

A DDoS attack works by overwhelming a target server, network, or application with a massive volume of internet traffic from multiple compromised computer systems.

1. The Botnet: The attacker uses a botnet—a network of thousands (or even millions) of computers and IoT devices (like unsecured smart cameras or routers) that have been secretly infected with malware.
2. The Command: The attacker, from a single command center, instructs all devices in the botnet to simultaneously send connection requests to your business’s public IP address or website.
3. The Overload: Your web server or router, unable to handle the legitimate requests plus the millions of fake requests, becomes overwhelmed. Its processing power and bandwidth are exhausted, causing it to crash or slow down to the point where no real customers can access your service.

The goal is simple: denial of service. The attack can last for hours or days, costing your SMB critical revenue and reputational damage.

3 Reasons Why DDoS Attacks Target SMBs

While DDoS attacks used to be reserved for large institutions, they are now frequently aimed at SMBs for several reasons:

1. Extortion: Often, the attacker will launch a small attack and follow up with an extortion threat, demanding payment (usually cryptocurrency) to stop the full-scale attack. They prey on the SMB’s fear of prolonged downtime.
2. Competitive Advantage: A less ethical competitor might use a DDoS attack to temporarily knock your website or e-commerce platform offline during a critical sales period (like a holiday sale), diverting traffic and revenue to their site.
3. Distraction: A DDoS attack can be a smokescreen. While the IT team is focused on mitigating the flood of fake traffic, the actual attacker may be using the distraction to quietly breach the perimeter and deploy ransomware or steal credentials.

Your SMB DDoS Survival Guide: Proactive Steps

Surviving a DDoS attack relies entirely on proactive planning and using services designed to absorb massive traffic floods.

1. Leverage Cloud-Based DDoS Mitigation

Your standard router or firewall is not designed to handle a large-scale DDoS attack—it will buckle immediately. You need professional cloud services that sit between the attack and your server.

• Content Delivery Networks (CDNs): Services like Cloudflare and Akamai distribute your website’s content across vast global networks. When an attack occurs, the flood is spread across thousands of servers, protecting your single origin server. CDNs also automatically filter malicious traffic.
• Cloud Security Providers: Services specifically designed to filter traffic. They analyze incoming requests and “scrub” the malicious botnet traffic before it ever reaches your network, passing only legitimate requests through.

2. Implement Network Segmentation (Isolate Critical Services)

If your primary website is hit by a DDoS attack, you need to ensure the attack doesn’t impact your internal operations.

• Actionable Step: Krypto IT implements Network Segmentation (VLANs). We ensure that external-facing services (like the web server) are separated from internal, critical functions (like accounting, email, and file servers). If the web server goes down, the rest of your business can continue operating locally.

3. Maintain an Immediate Incident Response Plan (IRP)

When the attack starts, you need to know exactly what to do. Panic and delay are the most expensive costs.

• Actionable Step: Your “Break Glass” File must include a specific DDoS protocol: immediately notify Krypto IT’s 24/7 support line, and prepare to reroute DNS traffic to a temporary “under attack” page to minimize system strain. You must have pre-arranged contact protocols with your hosting provider and your DDoS mitigation service.

4. Optimize Your Bandwidth and Hosting Plan

While you can’t buy enough bandwidth to stop the largest attacks, ensuring your hosting plan is robust and your internet service provider (ISP) has basic DDoS protection included is essential. Talk to your ISP about their baseline mitigation services.
