DDoS Attacks: What They Are and How to Prevent Them

In technology, businesses face a looming danger. DDoS attacks. Imagine a scenario where a hacker floods a network or server with fake internet traffic, causing chaos by overwhelming it. Legitimate requests get lost, services come to a grinding halt, and businesses suffer from disrupted operations, financial losses, and frustrated customers.

But amidst this threat, there’s hope! There are practical steps that businesses can take to protect themselves. This article aims to guide you through these measures, offering insights into preventing DDoS attacks and ensuring a quick recovery if one occurs. It’s all about staying vigilant and resilient in the digital landscape!

What is a DDoS Attack?

Distributed Denial service typically known as DDoS attack isn’t cyber trouble. It’s not about viruses or sneaky software. Think of it as a massive traffic jam caused by troublemakers, not a classic hack. Confusing, right?

Hackers take a different route- they don’t slip viruses into your system. Instead, they inundate your network or server with bogus traffic. Just like receiving endless fake phone calls, making it impossible to attend to the genuine ones.

They use these sneaky groups of hijacked devices called botnets. These botnets keep bombarding your server, making your website completely unreachable. It’s like locking all the doors to your place.

What happens next? Your business gets stuck; everything stops working. That’s what they call a distributed denial of service attack.

And it’s not just technical trouble. It can hurt your money if you don’t catch it fast. Extended downtime means losing cash and, even worse, losing your customer’s trust if you need to know what’s happening and think your site’s down.

If you’re not ready to protect and fix things, it worsens. The bad guys might even try to threaten you, showing they can mess with your system, and then ask for money to stop. And guess what? They want untraceable digital money that’s hard to track.

Different kinds of DDoS Attacks

DDoS attacks all have the same goal: To flood a system with an excessive amount of activity, hackers employ various tactics to execute this distributed denial of service.

Application-Layer Attacks

These focus on disrupting a specific app rather than the entire network. Hackers flood a target server with tons of HTTP requests, tiring it out from responding.

Security folks measure these attacks in requests per second (RPS). They often go after web apps, internet-connected apps, and cloud services. Stopping these attacks is challenging because it’s hard to tell the reasonable requests from the bad. And surprisingly, some hackers can pull off this attack with just one device.

Sometimes, you might hear this called a layer seven attack.

Protocol Attacks

Protocol-based DDoS attacks exploit weaknesses in how internet communication functions. In contrast to app-level attacks, these target slowing down the entire network.

There are two primary types of Protocol Attacks:

SYN floods: This disrupts the TCP handshake by bombarding the target with false requests, causing it to await a response that never arrives. This congestion ultimately leads to server crashes.

Smurf DDoS: Here, hackers use malware to create a loop of messages that continually crashes the system. These attacks are measured in packets per second (PPS) or bits per second (BPS) and are notable for their ability to bypass poorly configured firewalls.

Volumetric Attacks

These attacks gobble up a target’s bandwidth with fake data requests, causing traffic jams. Legitimate users can’t access services because of the attacker’s traffic.

Here are the main types of Volumetric Attacks

UDP floods: These flood ports with data packets using the UDP protocol.

DNS amplification: It redirects tons of DNS requests to a target’s IP address.

ICMP flood: This one overloads networks with false error requests.

These attacks hinge on the use of botnet groups—collections of infected devices. Hackers exploit these groups to trigger surges in traffic, effectively congesting all available bandwidth. Among the various types of DDoS attacks, these stand out as the most frequently encountered.

How to Protect Your Business Against DDoS Attacks

Preventing a cyber threat is always brighter than dealing with its aftermath. If cybersecurity isn’t your forte, seeking expert help might be the best bet. Consider hiring a cybersecurity company like Corporate Technologies to bolster your system’s defenses and learn practical ways to thwart DDoS attacks.

Here are recommendations from seasoned pros for businesses vulnerable to such threats:

Developing a customized DDoS response strategy is essential. Swift action, much like in any cyber crisis, is pivotal to mitigate the impact and restore stability to your systems. A well-crafted response plan is a guiding light for your team, enabling quick and efficient action during emergencies.

DDoS attacks differ significantly from other cyber threats. They disrupt networks in distinct ways, so your response plan should be tailored to counter this specific menace.

Start by assembling a response team comprising members from IT security, engineering, HR, and PR. This diverse mix ensures a comprehensive approach to tackling the challenge at hand.

Your plan should outline clear steps to detect and contain the attack, curbing its impact. Post-attack, assessing the extent of the damage and prioritizing the restoration of your devices and networks.

Effective internal communication is vital. HR is pivotal in managing internal communication guiding employees through the incident. Simultaneously, PR professionals handle external communications, ensuring accurate and timely information reaches the public without causing panic.

Boosting Network Security

To fend off DDoS attacks, it’s crucial to plug any security gaps that attackers might exploit. Your mission? Ensure those potential entry points are sealed tight by implementing top-notch security practices to safeguard your network.

First things first: Scout for software solutions tailored to your needs. Your main defense lies in robust firewalls, intrusion-detection systems, and high-quality anti-virus software. Think about enhancing your security further by incorporating additional layers of protection such as anti-spam content filtering, endpoint security, or web security tools. These layers shield you from various threats.

Securing your network infrastructure is equally vital. Ensure your devices are geared up to handle sudden surges in traffic. This proactive measure buys you time to investigate unusual activity and respond before your network buckles under pressure.

Numerous tools are available in the market specifically crafted to thwart DDoS attacks. Consulting cybersecurity experts such as Corporate Technologies can help you identify the most fitting and efficient solutions tailored to meet your unique business requirements. Their insights can steer you toward the right tools to shield your network from threats.

Monitoring Your Network Traffic

Staying vigilant is vital in tackling a DDoS attack effectively. It all starts with closely watching your network traffic. Why? Because reacting in time hinges on spotting the telltale signs of an impending attack. Remember, DDoS assaults bring a sudden surge in traffic, and sometimes, attackers test the waters with a smaller attack to fly under the radar.

Those traffic spikes should ring alarm bells for your team. But it’s not just the sudden rush; other anomalies can hint at a DDoS attack. Keep an eye out for unusual patterns like a massive surge in demand for a single application on your website (especially if no special event happens), inconsistent connectivity, sluggish page loads, or web crashes coming and going.

Here’s the golden rule: Train your team to react pronto at the first whiff of anything suspicious. Swift action at the onset of unusual activity provides the window to prevent a full-blown disaster.

Utilizing Multiple Servers and Harnessing Cloud Protection

Your in-house software and hardware serve as the first line of defense. But their capabilities have limits. It’s time to think beyond and extend your fortress to the cloud.

Why the cloud? Well, cloud providers offer an arsenal of security layers—firewalls and advanced threat monitoring tools—bringing a whole new level of protection. Plus, they provide extra bandwidth, empowering your website to handle more traffic than your private network ever could. This not only boosts performance but also safeguards your website’s stability.

Here’s the kicker: Clouds operate across multiple servers scattered across different locations. If one server hits its limit and crashes, others keep humming, ensuring your website stays up and running.

Clouds excel at secure data backups. In the event of a DDoS attack wreaking havoc on your system, having secure backups ensures a smooth transition to a secure version, minimizing the impact of the assault.

Embrace Top Security Measures

Security is a never-ending story, and a crucial chapter involves regularly changing passwords. Spread the word among your team—make it a routine. But here’s the kicker: adding a multifactor authentication system adds an extra lock to your network and accounts, a wise move for added security.

Quick reaction to cyber threats is key. Educate your staff on spotting signs of an attack and encourage them to report any suspicious activity promptly. It’s not just about spotting threats; guiding users on how to use your applications correctly is crucial, too. Provide them with a channel to report any hiccups they encounter.

Simple yet potent advice: Invest in robust software that suits your business needs and, most importantly, keep it updated. Seeking advice from an expert to cherry-pick the best solution for your system is a smart move. After all, the proper guidance ensures your fortress stays strong.

Conducting Security Assessments

Consistent security evaluations act as your fortress against lurking vulnerabilities within your network and connected devices. It’s pivotal to establish a routine: strive for assessments every quarter, or at least biannually. Why? These assessments provide the opportunity to identify any weaknesses or loopholes in your security setup before cybercriminals exploit them.
