Distributed denial-of-service (DDoS) has become one of the most complex and debilitating cyberattacks in the past years. It disrupts network service preventing the users from using the files or software programs that they need for work.
DDoS attacks cause serious downtime, decreased productivity, and revenue loss. That’s why businesses must be well versed in mitigating these attacks. Here’s how.
Secure your network infrastructure
Attacks as complex as DDoS can only be solved by using robust, multilevel protection strategies such as advanced intrusion prevention and threat management systems, virtual private networks (VPNs), anti-spam software, content filtering programs, and firewalls.
Together, these security strategies can identify inconsistencies in your network traffic, block the attack with the highest level of precision, and prevent a DDoS attack from ever happening.
In addition, you have to make sure your systems are up to date. DDoS attacks take advantage of outdated software and gaps in your security systems. By keeping your systems updated, upgrading to newer software versions, and patching programs regularly, you can better protect your infrastructure against cybercriminals.
Use the cloud
Standard network equipment are usually not built to withstand DDoS attacks, and that’s why for small- to medium-sized businesses (SMBs), acquiring cloud solutions on a per-user basis might be a better option.
Cloud providers can monitor the files in their cloud and block and contain malicious traffic before it harms your files. What’s more, software engineers who monitor your systems are always updated with the newest DDoS tactics, so they’ll always be ready for whatever new strategy cybercriminals might use.
Have a DDoS response plan in place
A team is only as strong as its weakest link. When it comes to protecting your infrastructure from a DDoS attack, you need to make sure that everyone involved in your DDoS response plan is well prepared.
Create a playbook of every detail in your pre-planned response, and include the names, contact details, and specific tasks of every person who may need to be brought in as part of your plan. You can run a simulated DDoS attack so you can respond faster when a real attack happens.
Moreover, communicating the problem with your clients should be part of your DDoS response plan. An attack can last up to 24 hours, and being transparent with your customers will help keep their trust and minimize business costs.
Know the signs of an active attack
Spotting an ongoing DDoS attack can be difficult because some of its signs are similar to other causes of service disruption such as technical network problems or system maintenance.
Familiarize yourself with the signs of a DDoS attack so you’ll know if it’s time to roll out your response plan. According to the US Computer Emergency Readiness Team (US-CERT), these signs indicate a DDoS attack:
- Unusually slow network performance
- Inability to access some websites
- Dramatic increase in the number of spam mails
Ask help from the experts
For very large attacks, hire a DDoS mitigation company or ask your managed IT services provider (MSP) if they have a partnership with one so you can minimize business interruption. Mitigation companies have large-scale infrastructure and top-of-the-line technologies that will keep your business online.
