Let VpsCity Equip Your Server Against DDoS Attacks

It’s one of the oldest cyberattack methods in existence – and one that’s been around for nearly as long as the Internet itself. We are referring to the Distributed Denial of Service (DDoS) attack. Although there are many different attack vectors a DDoS may exploit and many different methods through which it may achieve its purpose, at its core, every DDoS attack is the same – it floods its victim with bogus traffic or requests until that victim’s infrastructure buckles under the strain. Occasionally, this is done just to cause chaos, more frequently, however, a DDoS attack is a distraction tactic – like driving a bus through the front window of a store so no one notices a robber in the back. While a business is overwhelmed dealing with the fact that they are unable to function, hackers might make off with valuable data.

Learn To Recognise The Signs of an Impending DDoS Attack

If you do not already have network and server monitoring tools in place, install them. Familiarise yourself with your typical inbound traffic. If, for example, you typically receive 2000 visitors on Tuesday afternoon, it may be cause for concern if you suddenly see ten thousand pings on your website.

Pay close attention to your server’s performance, as well. If you notice routine tasks are taking an unusually long time or certain resources are unavailable, definitely contact your host. We at VpsCity, will work tirelessly to iron out all issues. While there is a chance it may simply be a service outage, there is also a possibility that you are under attack.

Finally, keep a close watch on any email accounts that are linked to your server, and the comments sections of any websites hosted on that server. A dramatic increase in spambot activity could indicate that it is time to shore up your defenses.

Take Preventative Measures With Your Server

As the old saying goes, an ounce of prevention is worth a pound of cure. While it is relatively little you can do against a complex DDoS attack without some sort of mitigation appliance, there are a few measures you can take. In addition to over-provisioning bandwidth (or choosing a host like VpsCity that can dynamically provision bandwidth to your site), you should take the following precautions:

  • Use an intrusion detection or prevention system or Web Application Firewall to detect attacks early.
  • Add filters that block packets from obvious sources of attacks (bogus/blacklisted IPs, infected devices, etc.).
  • Drop all malformed and spoofed packets.
  • Lower your thresholds for SYN, ICMP, and UDP Flood drops.

Use a DDoS Failsafe

A DDoS attack is meant to bring you offline – whatever secondary purpose it may serve, it is intended to deny legitimate users access to whatever services you offer. One way you can get around that is by implementing some form of failsafe tool. If a user is locked out from your site as a result of traffic blocking during a DDoS attack, give them the opportunity to reach out and address the issue.

Botnets lack the capacity to do so, which means you likely won’t have to worry about any unauthorised traffic making it through as a result.

Account For DDoS Attacks In Your Disaster Recovery Plan

DDoS attacks should be right up there with hardware failure, power failure, and natural disasters as a potential source of data loss – and you should have firm policies and processes in place for dealing with them before, during, and afterwards. Employees should be able to refer to a clear, step-by-step guide that gets them through even the worst denial of service attack.

It’s important that such tools reduce the apparent impact a DDoS attack has on your website or services. Ideally, you don’t want your users to have to wait to access your site during an attack – that’s how you lose your audience. Instead, the DDoS prevention platform you choose should allow legitimate users to access your site or application as though nothing is wrong.

Pay Attention To Other Suspicious Activity During An Attack

Last but certainly not least, remember that DDoS attacks are very often a mask for something far more insidious. You need to keep a close eye on your server while it is under attack. Install monitoring tools that automatically notify you of suspicious activity such as unusually large downloads, deletions, or duplication.

This will allow you to mitigate not just the DDoS attack, but the actual purpose behind it.

Let VpsCity Keep You Safe, Secure, And Stable

DDoS attacks can cripple your company if you let them – and not every business has the IT resources or staff necessary to operate a DDoS mitigation platform. That’s where VpsCity comes in. We include free, basic DDoS protection with every server, in addition to offering two levels of service to detect and mitigate larger, more sophisticated, sustained DDoS attacks.
