Denial-of-service (DoS) attacks, in which machines or networks are overburdened with requests, making them unavailable to users, cost businesses an average of $1.5 million a year according to a new report from Ponemon Institute, The Cost of Denial-of-Service Attacks.
Respondents reported that, on average, their companies suffered four DoS attacks in the same period. This experience caused many respondents to express scant confidence in their organization’s ability to deal with a DoS attack: only 14% rate their ability to prevent attacks as “highly effective”.
The most critical barriers to preventing DoS attacks were given as “insufficient budget” (49%), “lack of qualified security personnel” (46%), and “lack of C-level support” (32%).
Other report findings include:
- 82% of respondents said a DoS attack shut down all or part of their data center for an average of 9 hours in the same 12-month period.
- 64% of respondents said reputational damage was the main consequence of DoS attacks, followed by diminished productivity (35%), and revenue losses (33%).
- 44% say DoS attacks increased over the past 12 months, and 49% said they will increase over the next 12 months.
- DoS is in the top three security threats facing companies. (Zero-day attacks (56%), malware (45%), DoS (38%).)
