Given the tremendous economic and reputational costs of recent cyber attacks, executives are increasingly attempting to better understand the risk to their information systems. They’ve heard about the impact of data breaches on their peer corporations, and they’ve read about the huge fines levied by federal regulatory agencies. They’ve developed an increased sense of urgency to become better educated and are attempting to glean information from industry associations, industry journals, webinars, and conferences. What they often overlook, however, are the resources inherent in their in-house experts: their information technology personnel — their IT team. The challenge is, of course, that executives speak executive, and the IT team speaks technology. If only there was a conversational bridge…
This article will provide executive management with that conversational bridge. To begin, there are three things executives can do today which may provide some peace of mind:
- Engage their IT team in a structured conversation about the state of information security in their organization;
- Develop and test an information security incident response plan; and
- Identify and transfer any risk through cyber insurance that cannot be mitigated by technology.
If these suggestions are followed, executives can begin to create order amidst the digital chaos – and they’ll have a much better chance of keeping their corporate logo out of the headlines and off the regulatory radar. This article will focus primarily on engaging the IT team in a conversation about information security. It will not discuss incident response planning or cyber insurance. Those topics will continue to be addressed in other Digital Insights posts.
As background, there are internationally recognized standards and controls that recently made it out of the information security silo and onto the front pages of industry association journals. These standards and controls include those from the National Institute of Standards and Technology (NIST) and the Center for Internet Security (CIS). The controls from the CIS are known as the 20 Critical Security Controls. The Critical Security Controls comprised a prioritized list of network actions involving architectures, processes, products, and services that have proven to be effective against the latest digital threats.
The suggested conversation with the IT team is based upon questions about the Critical Security Controls. Executives need no further background than the questions themselves, but must be prepared to listen to the responses, follow up with questions about concepts, terminology, or technology that they don’t understand, and otherwise engage the IT team in a conversation.
One note of caution: if executives are going to ask questions about what the IT team is doing to protect the corporate infrastructure, they must be prepared to answer questions about their support for the IT program. Ultimately, this conversation will provide a great opportunity for executives to get to know the IT team and obtain critical information security education.
And now for the Critical Security Controls…The following is a list of the Critical Security Controls combined with questions that can guide a conversation with the IT team about the status of an organization’s cybersecurity:

Don’t be afraid to ask questions! Executives can obtain some peace of mind about the state of their corporate information security through a conversation with their IT team. If the conversation produces anxiety rather than peace of mind, it obviously needed to occur. Either way, an important first step in information security is to identify what it is and then begin managing the process of helping the IT team achieve their target goals: the best practices in the industry.
Although no one can control the threats against information systems, they can control the risks: the vulnerabilities to the threats. By increasing an organization’s security posture and reducing its vulnerabilities, the likelihood of the corporate logo being in the headlines will be reduced, as will the likely costs of an incident. And don’t forget – make sure incident response planning and the acquisition of cyber insurance are on the priority checklist!
