How do I know if I am experiencing a DDoS attack?

Signs include: sudden dramatic increase in traffic, website or service becoming very slow or completely unavailable, traffic coming from unusual geographic locations, traffic patterns that do not match normal user behaviour, and network monitoring alerts for bandwidth saturation. DDoS protection services can automatically detect and alert you to attacks.

Can small businesses be targeted by DDoS attacks?

Yes. DDoS-for-hire services make it cheap and easy for anyone to launch attacks. Small and mid-market businesses are targeted for competitive sabotage, extortion, hacktivism, or simply to test attack tools. The low cost of attacks means no business is too small to be a target.

What is the best DDoS protection for a mid-market business?

Cloud-based DDoS protection services like Cloudflare, AWS Shield, or Azure DDoS Protection are the most cost-effective solutions for mid-market businesses. They can absorb massive attack traffic without requiring expensive on-premises hardware. Many offer free or low-cost tiers that provide basic protection, with premium tiers for more advanced mitigation.

DDoS Attack

Distributed Denial of Service

Also known as:distributed denial of serviceDDoSdenial of service attack

A Distributed Denial of Service attack that overwhelms a target server, service, or network with a flood of internet traffic from multiple sources, making it unavailable to legitimate users.

In-Depth Explanation

A Distributed Denial of Service (DDoS) attack attempts to make an online service unavailable by overwhelming it with traffic from multiple compromised systems (often a botnet). Unlike a simple DoS attack from a single source, DDoS attacks are distributed across many sources, making them harder to mitigate.

Types of DDoS attacks:

Volumetric attacks: Flood bandwidth with massive traffic (UDP floods, DNS amplification)
Protocol attacks: Exploit network protocol weaknesses (SYN floods, Ping of Death)
Application layer attacks: Target web application vulnerabilities (HTTP floods, Slowloris)

DDoS attack characteristics:

Traffic comes from many different IP addresses simultaneously
Can range from gigabits to terabits per second
Duration varies from minutes to days
Often used as a distraction for other attacks
Increasingly available as DDoS-for-hire services

DDoS mitigation strategies:

Cloud-based DDoS protection: Services like Cloudflare, AWS Shield, or Akamai absorb attack traffic
Rate limiting: Restrict the number of requests from individual sources
Traffic analysis: Distinguish legitimate traffic from attack traffic
Anycast network diffusion: Distribute traffic across a global network
Web Application Firewall (WAF): Filter malicious application-layer requests
Overprovision bandwidth: Maintain capacity headroom for traffic spikes
Incident response plan: Documented procedures for DDoS response

Impact on businesses:

Website and application downtime
Revenue loss from unavailable services
Customer frustration and brand damage
Potential data breach if DDoS is a diversion tactic

Business Context

DDoS attacks can take a business offline for hours or days, resulting in lost revenue, damaged reputation, and frustrated customers. The barrier to launching attacks is low, with DDoS-for-hire services available for as little as $10.

How Clever Ops Uses This

Clever Ops protects Australian businesses from DDoS attacks by implementing cloud-based DDoS protection services, configuring rate limiting and traffic filtering, and building incident response procedures for rapid mitigation when attacks occur.

Example Use Case

"An Australian e-commerce site is taken offline by a volumetric DDoS attack during peak sales season. After implementing Cloudflare DDoS protection, subsequent attack attempts are absorbed without affecting site availability."
