Network failure due to DDoS attacks

Why you should be focusing on DDoS attacks

As a critical facility and data center operator, we are constantly identifying ways to help you mitigate your risks of network failure and unplanned downtime. This month, DDoS attacks top the list.
In the past few weeks, we’ve discussed power failure and some of the ways in which we mitigate the greatest issue posed by UPS battery systems, which ranked #1 in causes for data center outages in 2019. Coming in #2 for the first time, according to a recent Uptime Institute report1, is network failure due to Distributed Denial of Service (commonly known as DDoS attacks).

Overview of the 3 most common causes of data center downtime:

  1. Uninterruptible Power Supply (UPS) Battery Failure (we cover this in-depth in our UPS Battery Failure posts)
  2. Network Failure Due to DDoS Attacks
  3. Software & IT Systems Issues

DDoS attacks confound even sophisticated IT teams.

Within the IT industry, security management of the business has grown to be one of the most critical components of an IT department. Most financial institutions, legal firms, technology organizations and the like have entire teams dedicated to information security in an effort to maximize client data security and protect the business from malicious activity, both external and internal, targeting the organization.
While commonly known security measures are in place for most organizations, including email, phishing, malware and bots, and social engineering threats are now becoming a part of onboarding and training, DDoS attacks keep even the most disciplined IT teams on edge.

What exactly is a Distributed Denial of Service attack (DDoS)?

A DDoS attack is a malicious attempt to disrupt the normal traffic flow of a server, service or network by overwhelming the target (or its surrounding infrastructure) with a massive flood of internet traffic. It’s like creating a traffic jam on a highway. Instead of the typical flow of traffic that is transported, an attacker sends exponentially more traffic simultaneously through compromised computers (called bots) in an attempt to shut down or take over the system. The attacker can range from a lone wolf hacker taking your system for a joyride to a cybercriminal or nation-state whose objective is to take down a prominent website, install malicious software, steal data, swipe trade secrets, extort money or even make a political statement.
A DDoS attack can take a number of forms and can be launched at any layer in the network.

Common DDoS attacks include:

  • HTTP Flood
  • SYN Flood
  • DNS Amplification

At Cavern Tech, we are constantly planning and preparing for as many of the causes for data center outages as possible. We are actively tracking emerging DDoS trends each day to ensure that no new hazard becomes a threat to our clients’ uptime.
