Realize The Need For Risk Management

For years security vendors have been able to play off the general fears of malware and cyber attacks. They’ve advised that if we just bought this product we’d be more secure. As the scope of protecting data has become more complex, we’ve slowly learned that deploying more security controls alone is not a risk management solution.

“We could spend tons and tons of money and not know if we had improved security at all or if we had done the right things,” said Eric Cowperthwaite, (@e_cowperthwaite), CISO at Providence Health & Services in Seattle. “We needed a better way than just installing all the technology you can buy to figure out what we should be doing in our security program.”For Kirk Herath, VP, CPO, Associate General Counsel, Privacy, Technology & Contract Services at Nationwide Mutual Insurance Company, building a risk management practice is a requirement in their heavily regulated industry.

Risk Management Is What You Do Beyond Basic Controls

“There is a basic set of security controls that must exist from an ‘I have done the right things in a due diligence perspective,’” noted Cowperthwaite.

For example, said Cowperthwaite, with physical security you put locks on doors, add alarm systems, and closed circuit TV. Although there isn’t a full consensus on information security of what that basic set of security controls should be, most know to include anti-virus, firewalls, intrusion protection systems, and spam filtering.“This is not risk management at all. This is equivalent to putting a lock on the door,” said Cowperthwaite.

Patrice N Hall - Assessing Your Assets Is Table Stakes

“If you don’t know what your crown jewels are you can’t do risk management,” said Cowperthwaite. “If I don’t know what it is that I need to protect on behalf of my organization I can’t possibly be successful in going beyond foundational due diligence security.”

“You need to understand as a security practitioner what data is important to your board if it gets out and what data is important to just the functionality of the organization,” said Erin Jacobs (@SecBarbie), CIO/CSO for UCB, Inc. “Understand how data moves in and out of the organization.”

After doing a data map, Jacobs learned, “What’s important to the board is not necessarily what’s important to the business units. And what’s important to the business units might be different to what’s important to security teams.”

Patrice N Hall - Find The Business’ Risk Tolerance

“You can write rules that are risk-averse and risk-absolute. We have found that is a recipe for disaster,” said Herath who advised instead that you have discussions with the business about their risk tolerance.“We assess the risk appetite of our organization and the organizations we serve and apply controls around that.”

Be wary that even though security controls can reduce risk, it may cause the business to act more risky therefore not reducing damages. This phenomenon is a function of risk compensation or the Peltzman effect, introduced by Sam Peltzman, who noticed that safety restrictions on cars, such as seatbelts, don’t reduce fatalities. It just makes people more dangerous drivers, said Andy Ellis (@CSOAndy), CSO for Akamai.“People have a set point of risk tolerance. There is so much risk that they will tolerate and every time you take risk away, they accept more,” said Ellis.

Patrice N Hall - Risk Can Be Determined By Regulators

While compliance does not equal security, falling out of compliance can be financially damaging and therefore highly risky.“We exist because of GLBA ,” admitted Herath of how regulators often manage his risk. “It’s hard in a highly regulated industry to make what academics might think is a perfect risk calculation.”

While Nationwide has had an practice prior to GLBA, Herath confessed that it changed dramatically as a result of this regulation.

Cowperthwaite agrees and points out that HIPAA security rules dictate that his health organization must have access management. It’s not an addressable specification, it’s a requirement. Referring to “TIP 2,” it’s not risk management at all, but rather a basic foundational thing that he has to do.

Patrice N Hall - Get Input On How Well You’re Doing

While Cowperthwaite’s team surveys business leaders on what information they think is important, they also ask how well they think the team is doing to protect it.

Answers to that question can greatly change the risk profile, said Cowperthwaite. For example, when they asked how important cybercrime was, it was listed, by importance, in the middle of the pack of 40 issues.

But when they asked the business how well they thought they were doing to protect against cybercrime, they didn’t think it was going so well so the issue moved up in importance.

Patrice N Hall - Use the Simple Principle

Don’t try to numerically quantify risk-based security management. There’s a belief that risk-based security management can be boiled down to numbers and that you can quantify the risk and compute the annualized loss, said Ellis.“Well, I expect I could lose this much money. So if I spend this much resources then I can mitigate it by this percentage and that was a good investment,”

While Ellis thinks this might work for fraud and petty theft, he doesn’t believe it will ever work for general information security because of the qualitative variables.

The desire to quantify is understandable since a lot of risk speakers at conferences are from the financial services area, noted Taylor.
