DDoS: Understand Attacks & Protect Your Business

How Do DDoS Attacks Work?

There are several ways to run a DDoS attack. The most common ones are:

Volumetric Attacks

These attacks try to use up a network's bandwidth with a flood of fake data. They often send millions of requests per second. This clogs the network and blocks real traffic.

Protocol Attacks

These attacks use up the resources of the server or of network devices. One example is the SYN flood. It opens huge numbers of half-open TCP connections and never closes them.

Application Layer Attacks

These attacks target weak spots in server software or apps. They overload the app by using up its computing power. For the attackers, this takes very little effort.

Typical Impact of DDoS Attacks

A DDoS attack can do great harm. This is true above all for companies that need their network to run all the time. Typical effects are:

• Lost revenue: When online services go down, customers can no longer shop or use them.
• Cost of the cleanup: Companies often have to spend a lot to deal with a DDoS attack. This includes technical support and IT security experts.
• Damage to your name: Frequent or long outages can hurt customer trust for good.

Protective Measures Against DDoS Attacks

Companies should take several security steps to protect themselves against DDoS attacks:

Network Monitoring

Use network monitoring tools that spot unusual traffic. Then you can take action quickly.

Scalable Infrastructure

Use cloud services and content delivery networks (CDNs). They can absorb large spikes in traffic and spread the load.

DDoS Protection Solutions

Invest in dedicated DDoS protection systems. They detect suspicious activity and respond to it. They can often filter out harmful requests and keep normal operations running.

Case Studies

In recent years, there have been many well-known DDoS attacks. They serve as warnings:

• Attack on Dyn in 2016: A massive DDoS attack took down popular websites such as Twitter, Netflix and Reddit. The attackers used a botnet made up of IoT devices.
• GitHub attacks: In recent years, DDoS attacks have briefly disrupted this well-known developer platform several times.

Best Practices for DDoS Protection

Good DDoS protection needs a clear plan. These steps have proven useful:

• Know your attack surface: Find out which of your internet-facing services are critical to your business and need special protection.
• Arrange protection in advance: Agree with your internet provider or a DDoS protection provider on what steps take effect in an emergency.
• Write an incident plan: Set roles, escalation paths and how you will talk to customers during an attack.
• Limit requests: Use rate limiting and keep spare capacity for peak loads.
• Test regularly: Check your protection and emergency steps in drills.

Common Challenges

• Telling real peaks from attacks: High traffic, for example during a marketing campaign, must not be blocked as an attack by mistake.
• Application layer attacks: They look like normal user behavior. So they are harder to detect than volumetric attacks.
• Relying on providers: The protection from your providers and CDN vendors must fit your needs, both in the contract and on the technical side.

Measuring Success and KPIs

You can measure how well your DDoS protection works with metrics like these:

• Uptime of business-critical services
• Time to detect and stop an attack
• Share of real requests blocked by mistake
