First US Federal CISO Shares Security Lessons Learned

Greg Touhill's advice for security leaders includes knowing the value of information, hardening their workforce, and prioritizing security by design.

INSECURITY CONFERENCE - Washington, DC - Greg Touhill encouraged his audience of security leaders, whom he dubbed "the cyber neighborhood watch," to swap war stories and lessons learned during his keynote at Dark Reading's inaugural INSecurity conference, held this week in Washington, DC.

As the first CISO of the US federal government, and with an extensive background in government cybersecurity and the military, Touhill has several stories of his own. Drawing from years of experience, the Cyxtera president shared his own lessons learned to kick off an event created to bring cyber defenders together so they can discuss problems and challenges.

One of the biggest problems is explaining to the business how cybersecurity is a risk management issue. Most security pros struggle to communicate with business leaders, who "speak a different language than we do," he explained.

"I keep on hearing executives talk about cybersecurity being a technology problem, and they keep pouring money into buying new stuff," said Touhill as an example. The enterprise instinct to buy new protective tools often distracts them from the core problem of managing risk.

One of Touhill's lessons was to avoid chasing fads. Sometimes new doesn’t mean improved, he noted. Security leaders need to keep tech current, not buy every new tool. They should do their homework and base their product decisions on both risk potential and business value.

Knowing the value of corporate information is a key part of evaluating and managing risk. Business leaders know their data exists but can't explain what it means or how much it's worth. It's tough to know where to prioritize security if you don't know which data is most valuable.

"Information is one of the most valuable assets any business, any operation has," Touhill emphasized. "Look at your infrastructure, look at how you architect. Know the value of your information and don't try to defend everything. Defend what you need to defend."

Security leaders must also prioritize security by design, he continued, using the transition to the cloud as an example. "A lot of folks jumped into the cloud without knowing about the tall, craggy mountains on the other side of that cloud," he pointed out.

Touhill's lessons extended to security employees. "Humans fail all the time," he said, but you can bring down the risk of catastrophic events by training people and making sure they're appropriately resourced. Hardening the workforce is "critically important."

"People are your weakest link but also your greatest assets," Touhill continued. It's up to security leaders to make the business case for additional training, which is necessary but expensive. The need for education will never go away. Team members, and colleagues across the enterprise, should be taught to "think like a hacker" and "be very suspicious."

The sentiment extended to another lesson: have a zero-trust model. Most security pros haven't taken a full inventory of all the trust relationships they have, he argued, encouraging the audience to look at where their trust lies and "be skeptical." Knowing and remembering the value of information will be critical as a new wave of professionals enters the workforce.

"We're raising a generation of folks who are freely surrendering their privacy - your privacy - by giving up information and not recognizing the value of it," Touhill said.

Other lessons touched on security fundamentals. He urged the audience to identify where they aren't mastering basics or being consistent. "How many times has someone gotten breached and left the backdoor open?" he asked, relating his advice back to thinking like a hacker.

Attackers will go for the underbelly, Touhill continued. They will check every door and window to make sure they are locked. And if they're not, they will take advantage of it.

Ultimately, along with protective measures and strategies, leaders must also "be prepared for a really bad day," he concluded. Security teams identify risk and threats, protect against them, and often build response plans but rarely exercise them to practice for a real incident. Those who need to practice the most often don't.

In the best organizations, everyone participates in cyber exercises and drills - even the boards and the CISOs. "A bad day is going to come for each and every one of us," Touhill emphasized.

Re: Executives wait for "technologists" to lock their own front doors
@SchemaCzar: Not just executives -- even the very top executives. An MIT professor once told me a story of how a company sent out "fake" phishing emails to its employees as a test, and one of the people who clicked on the link was a C-suite executive. When asked why he clicked on the link, the C-suiter responded, "I wanted to see what would happen."

Executives wait for "technologists" to lock their own front doors
Reading security news and the general news, I conclude that Touhill needs to talk tougher to executives.  There are too many stories of executives who can't be bothered to follow the same security policies that must be followed by others in the organization.  They are the highest-value person targets in the organization, and they often feel they can dump their own security on an underling, or worse, that security is the organization's problem rather than their personal responsibility.  I recently heard of a high-level VP in a large, regulated business who flat-out refused to follow password change, or even password complexity policy.  This was before password change policies were brought into question, but long after secure password managers were available that make password change and complexity requirements manageable.

Touhill is right that these executives think cybersecurity is a technology problem.  So is the physical security of their own homes: a technology problem.  If they treated home security the way they do organizational security, they wouldn't even lock their own front doors.

Basics
Reminds me of that old reality show "To Catch a Thief," which demonstrated to people how easy it was for burglars to break in and steal them blind in a matter of about ten minutes. Almost all the time, there was an unlocked window or unlocked door.

Same thing in cybersecurity. The bad guys don't go right to sophisticated techniques. They go to basic, common passwords and they go to recently announced zero-days to check for a lack of a patch.
