[eBook] A Step-by-Step Guide to Cyber Risk Assessment

In today’s perilous cyber risk landscape, CISOs and CIOs must
defend their organizations against relentless cyber threats,
including ransomware, phishing, attacks on infrastructure, supply
chain breaches, malicious insiders, and much more. Yet at the same
time, security leaders are also under tremendous pressure to reduce
costs and invest wisely.

One of the most effective ways for CISOs and CIOs to make the
best use of their limited resources to protect their organizations
is by conducting a cyber risk assessment. A comprehensive cyber
risk assessment can help:

• Identify vulnerabilities and threats
• Prioritize security investments
• Assess cybersecurity maturity
• Communicate cyber risk to executives
• Provide the basis for cyber risk quantification

A new guide by cybersecurity optimization provider CYE (download here^[1]) explains how this can
be accomplished. The guide outlines several approaches to cyber
risk assessments and describes the necessary steps that can yield
solid insights and recommendations for security leaders.

Conducting an effective cyber risk
assessment

There are various approaches to conducting a cyber risk
assessment—each with its own pros and cons. All, however, involve
understanding an organization’s security posture and compliance
requirements, collecting data on threats, vulnerabilities, and
assets, modeling potential attacks, and prioritizing mitigation
actions.

According to the guide^[2], an effective cyber risk
assessment includes these five steps:

1. Understand the organization’s security posture
   and compliance requirements
2. Identify threats
3. Identify vulnerabilities and map attack
   routes
4. Model the consequences of attacks
5. Prioritize mitigation options

A cyber risk assessment also creates the basis for cyber risk
quantification, which puts a monetary value on the potential cost
of cyber threats versus the cost of remediation. CRQ can help
security experts pinpoint which vulnerabilities in the
organization’s threat landscape pose the greatest threat and
prioritize their remediation. It also helps CISOs communicate the
cost of cyber risk to management and justify security budgets.

Creating a cybersecurity roadmap

Conducting a cyber risk assessment is only the first step. The
insights and recommendations that are yielded from the assessment
can set the stage for creating a roadmap for how the organization’s
cyber posture will be strengthened in stages. Then the team can
track, measure, and quantify cyber resilience over time. The
assessment should also be revisited periodically to address any
emerging threats, changes to the business, and changes to the
organization’s technologies, IT architecture, and security
controls.

To effectively assess, quantify, and mitigate cyber risk,
organizations should be sure to have the right tools and platforms
in place, as well as dedicated professional guidance and advice
provided by established cybersecurity experts.
