Data breach costs on the rise

Annual Ponemon study provides insights on the financial impact of cyber-attacks

Given the number and severity of publicized data breaches over the past year, it should come as little surprise that the average cost of a data breach is on the rise. According to the “2015 Cost of Data Breach Study: Global Analysis,” which was conducted by the Ponemon Institute and sponsored by IBM, the average cost of a data breach increased from $3.52 million in last year’s study to $3.79 million in this year’s edition.

While the year-over-year jump may seem small, the rise actually represents a 23 percent increase in the total cost of a data breach since 2013. The research, which included responses from personnel at 350 companies spanning 11 different countries, also found that lost business as the result of a data breach potentially has the most severe financial consequences for organizations as these costs increased from an average of $1.33 million last year to $1.57 million in 2015. Lost business costs include; abnormal turnover of customers; increased customer acquisition activities; reputation losses; and diminished goodwill.      

Diana Kelley, executive security advisor for IBM Security, said one thing that really stood out to her was the root causes of data breaches examined in the study, the majority of which (47 percent) were found to be the result of malicious or criminal attacks. The study found that the average cost per record to resolve such an attack is $170, compared to system glitches which cost $142 per record to resolve and human error or negligence that cost $134 per record to correct.  

“That indicates something that we’ve seen in other studies that this is organized criminal activity for data breaches,” she said. “We’re moving past the random, somebody left their laptop in a car, and we’re really looking at very targeted attacks from organized criminals.”

Kevin Beaver, an IT security consultant with Atlanta-based Principle Logic LLC, said that data breaches continue to persist on such a massive scale because many companies mistakenly believe they can just buy a piece of security technology that will take care of all of their problems.

“It doesn't work that way,” he said “Even if you have the very best of security controls you still have to have ongoing oversight and vulnerability testing because things are going to fall through the cracks.”

Another common issue, according to Beaver, is that companies simply place too much trust in employees and vendors.

“It's always best to err on the side of caution and put the proper controls in place so everyone, and especially the business, are setup for success. Another big issue I see is all the organizations, especially in the healthcare industry, that believe their high-level audits and policies are sufficient for minimizing their risks. It's not. Unless and until you test for - and resolve - the growing amount of security vulnerabilities on your network, you're a sitting duck waiting to be made to look bad,” said Beaver. “This is especially true to social engineering (i.e. phishing) testing. It's unbelievable how many people are still gullible and give up their network credentials or other sensitive info without question.”

Although data breaches that involve the theft of credit or debit card numbers seem to carry a greater amount of weight with the media and public in general, Kelley said the data shows that things such as protected health Information (PHI) and other personal data are more coveted by hackers as they have a longer lifespan for resale. Kelley advises companies to identify what their “crown jewels” are from a data perspective and to conduct threat assessments and risk modeling around protecting those assets.

“I think organizations need to look at the big picture. We do see evidence of more sophisticated criminal, organized attacks. On the other hand, we can’t forget all of the good security hygiene and just try and focus on what’s the next big scary attack,” said Kelley. “We have to do a very robust, layered set of security throughout our organization to include security awareness and training and monitoring. You’re looking for anywhere in that stack where there could be an exposure or there could be a vulnerability. Companies need to not just think about the big attack, but really think about a robust security model because that is going to help prevent the smaller attacks, as well as the larger attacks.”

Perhaps one of the study’s silver linings is that the involvement of a company’s board-level managers was found to help reduce costs associated with data breaches by $5.5 per record. Insurance protection was also found to reduce cost by $4.4 per record. Despite the increased awareness and involvement by senior leadership, Kelley said companies cannot completely protect against the threats posed by hackers.

“It’s important to remember that awareness and ability to stop something aren’t necessarily always aligned. If we look in the real world, we’re all very aware and highly concerned about something like cancer, but preventing it is very, very difficult,” said Kelley. “We can have the C-suite be very aware of security, but still some companies are at different levels of maturity. Attackers, they are, again, organized and sophisticated, so the level of prevention and controls you need in place to stop the attacks is very high. The fact that we still have attacks going on doesn’t mean companies aren’t putting security controls into place.”   

However, Beaver adds that while some executives may say and do all of the right things in public when it comes to their data protection efforts, the reality is some of them are just paying lip service to the issue.

“It's all about policies and related security theater to appease those not savvy enough - or politically powerful enough - to look deeper or question things further,” said Beaver.  

Conversely, Beaver said that there are a lot of companies who are taking the right approach to cybersecurity, which involves recognition by senior management of the seriousness of the issue.

“I see many organizations doing security well,” he added. “The key characteristics of well-run security are: executive acknowledgement of the challenges, ongoing financial and political support for IT and security teams, periodic and consistent security testing, and the willingness to make changes where changes need to be made - even if it's not politically favorable.”

Another bright spot in the study was that it found a correlation between organizational preparedness and reduced financial impact of a data breach. Companies that employed some level of business continuity management (BCM) within their organization were able to reduce their costs by an average of $7.1 per compromised record.

“Companies that brought in an incident response team or had an incident response program in place were able to save $12.60 per record,” added Kelley. “The biggest takeaway is to get some kind of plan in place. Have business continuity, have an incident response plan in place and be continually detecting and monitoring activity on the network so that if a breach is occurring, you can either see the very beginning of it or you can see one in process and respond as quickly as possible to reduce the impact to the business.”
