With cybercrime ranking as the No. 2 culprit for data center outages, new studies are revealing that Denial of Service (DoS) and Distributed Denial of Service (DDoS) are alarming trends among cyberattack incidents.
Considered the most common form of cyberattacks against data centers, DoS and DDoS have risen significantly in the past year, according to a study by Akamai Technologies. The study revealed that DDoS attacks increased by 125.36 percent on an annual basis from Q1 2015 to Q2 2016.
A DDoS attack, which entails shutting down a system through the use of multiple compromised systems, is often attributed to a virus. Because of the innovation of cheap botnets, Akamai reported, these attacks are increasingly easier to carry out.
The Ponemon Institute, a research center, also noted a substantial rise in DoS attacks. From 2010 to 2015, DoS attacks increased in frequency by 59 percent.
In a study of more than 270 organizations during a six-year period, it found that costs of the attacks ranged from $14,000 to $2.35 million. Also, 49 percent of the companies surveyed faced a partial or complete shutdown as a result of a DoS attack. In 32 percent of those DoS incidents, survey respondents experienced a partial outage. About 17 percent had a total outage because of the DoS attack. The average cost of a total outage was $610,000.
According to the Ponemon Institute, companies that seemed to do a better job avoiding outages in the wake of a DoS attack had the following processes or systems in place:
- Command and control governance structure.
- High data center redundancy.
- Network intelligence tools.
- Advanced threat intelligence.
- Well-defined incident response plans.
- Enterprise deployment of anti-DoS tools.
