Businesses today depend enormously on being online to engage customers, create sales, and keep in touch. Hence, the more we rely on the internet, the more cyberattacks and DDoS (Distributed Denial of Service) attacks, etc. These attacks can paralyse your business network, resulting in massive financial and reputational losses. DDoS protection that protects your business network from attack helps maintain your ability to operate. This guide will cover how DDoS protection works, the risks of these attacks, and the tools you need to protect your business from an attack.
Understanding DDoS Attacks and Their Impact
A Distributed Denial of Service (DDoS) attack attempts to disrupt the normal functioning of a targeted server, service, or network by overwhelming it with a flood of internet traffic. The traffic often originates from many sources, frequently botnets (a network of private computers infected with malicious software and controlled as a group without the owners’ knowledge) or compromised devices (devices that have been hacked and are under the control of a malicious actor), making it hard to halt the attack by blocking a single source. A DDoS attack aims to overwhelm the resources of the attacked system, leading to slower operation, a crash, or total unavailability.
However, the consequences of a DDoS attack can be catastrophic for a business. Websites and online services can go offline, leading to lost revenue, missed customers, and brand attrition. In some cases, companies are forced to shut down operations for days to minimise the damage, resulting in additional losses. Moreover, DDoS attacks can be used as a diversion tactic to cover up a data breach or malware outbreak. The potential impact of a DDoS attack underscores the urgent need for robust protection measures.
Why DDoS Protection Is Essential for Businesses
With increasing numbers of businesses shifting operations online, the importance of solid cybersecurity measures becomes increasingly evident. Enterprise DDoS protection protects your business’s network infrastructure and ensures customer services are available 24/7. With this protection, your business risks can avoid extended downtime, financial loss, and a damaged brand reputation.
However, in sectors such as e-commerce, financial services, and healthcare, where life is critical, the effects of a DDoS attack can be catastrophic. When a DDoS attack takes an online store offline for hours, thousands of dollars worth of lost sales can be at stake. Likewise, an attack on a financial institution’s network would delay transactions, resulting in customer dissatisfaction (if not worse) and potential fines by regulators.
With DDoS protection in place, you can ensure your business’s continuous availability, even during attacks. This allows you to focus on growing your customer base and retaining existing customers, knowing that your business operations are secure.
How DDoS Protection Works
Available DDoS protection uses various methods and tools to detect, mitigate, and prevent attacks from reaching your network. The objective is to select out harmful enterprising, while bona fide enterprising does not stop the past. Here are a few common strategies involved in DDoS protection:
1. Traffic Filtering and Rate Limiting
DDoS protection is a tool against denial-of-service attacks, which are not de facto forms of filtering—filtering traffic by known attack patterns is one of the significant tools. This process involves examining incoming traffic and deciding between legitimate users and malicious traffic. Filtering tools look at several things, from the source IP addresses to the frequency of requests to the sizes of data packets. Businesses can filter out malicious traffic and set rate limits to prevent excessive requests and the network from being overwhelmed.
2. Load Balancing
Load balancing eases resource strain by distributing traffic across multiple servers or data centres. It helps your network cope with high traffic volume by spreading the load, which reduces the risk of slow or unavailable sites. For example, this can mitigate a DDoS attack, as load balancing spreads requests across multiple servers instead of allowing the attack to pile on one server.
3. Intrusion Detection Systems (IDS)
An IDS monitors network traffic and catches abnormal patterns indicating an attack. These systems examine traffic in real time and will send alerts if something suspicious is detected. When used along with other security solutions, IDS can detect and react swiftly to DDoS attacks before they become a significant issue.
4. Cloud-Based DDoS Protection
Now that businesses are migrating to the cloud, cloud-based DDoS protection solutions continue to gain popularity. They can automatically detect and mitigate a DDoS attack by routing traffic through an extensive network of servers. Cloud providers generally have far more bandwidth and resources than you and can weather large-scale DDoS attacks without impacting the performance of your business network. Cloud-based solutions can also quickly scale upward to manage spikes in traffic when an attack occurs, making them an ideal solution for businesses with variable or unreliable traffic volumes.
5. Scrubbing Centres
A scrubbing centre is a dedicated facility that examines incoming traffic during a DDoS attack. When an attack is detected, traffic is diverted to these centres, where it is “scrubbed” by purging out malicious packets. This clean traffic is returned to your network so only genuine users can access your site. Scrubbing centres allow for the minimisation of the impact of DDoS attacks and the keeping of services available.
Types of DDoS Attacks and How Protection Mitigates Them
Multiple forms of DDoS attacks target distinct layers within your network. Some of the most common are:
1. Volume-Based Attacks
These volume (or bandwidth) attacks flood a network with traffic. These attacks can be mitigated via traffic filtering, rate limiting, and load balancing. Limiting requests from any one source and filtering out known bad traffic can help businesses ensure that their network is not full of users and bad people just trying to slow things down.
2. Protocol Attacks
Protocol attacks are aimed at TCP or Internet Control Message Protocol (ICMP) vulnerabilities. Specific types of attacks can be prevented by using special-purpose security mechanisms, including firewalls (which act as a barrier between your network and the Internet, allowing only authorised traffic to pass through) and Intrusion Prevention Systems (IPS), which watch traffic to prevent attempts at abuse of a protocol and can block malicious packets before they succeed in damaging the system’s operation.
3. Application Layer Attacks
Application layer attacks are more targeted and sophisticated, directly targeting specific applications or services to make them dysfunctional. Such attacks tend to replicate legitimate user behaviour, making them challenging to identify. Businesses require sophisticated DDoS defence against application layer assaults, including behavioural analysis and real-time traffic monitoring to spot anomalous patterns and thwart attacks before they can compromise vital applications.
Steps You Can Take to Enhance DDoS Protection
Enterprise DDoS protection tools and services will be a crucial part of the game to defend your business, but here are some proactive measures that can increase your overall security posture:
1. Educate Your Team
The key to solid cybersecurity is employee awareness. Ensure your team knows the DDoS attack signals and how to respond quickly if an attack is executed. Educating employees on recognising suspicious activity and best practices for securing their online systems can help prevent successful attacks.
2. Invest in Robust Network Infrastructure
Network redundancy is critical for surviving DDoS attacks. This extends to using multiple data centres, redundant servers, and superhighway connections. However, if your network is built to weather traffic storms and includes redundancy, the odds that you will suffer downtime from a denial-of-service attack are significantly reduced.
3. Regularly Update Your Security Systems
Cybercriminals are always innovating, so it’s important to keep your security systems current. Regularly updating your firewalls, intrusion detection systems, and DDoS protection tools helps keep you one step ahead of emerging threats and strengthens your defences against them.
Conclusion
DDoS protection is essential to any organisation’s cybersecurity strategy. With cyberattacks becoming increasingly sophisticated and frequent, protecting your network from DDoS threats is more critical than ever. Traffic filtering, load balancing, and cloud-based solutions will help reduce some of the DDoS attack effects, but in the long run, more proactive actions will need to be taken if businesses stay online for the long haul. You can ensure that your business is running, secure, and able to serve your customers despite the cyber threat as long as you have the proper protection.
