That means CISOs need to look beyond the short-term challenges of recent weeks and start thinking about the ongoing risks from a distributed workforce and how they would affect the bottom line.

By utilizing the RiskLens SaaS platform, running on the FAIR standard for cyber risk quantification, analysts can quantify probable risks in dollars and cents for WFH loss events such as:
Quantitative Risk Analysis for Unpatched Endpoint Vulnerabilities
One specific example from above would be looking into the potential ramifications of an unpatched vulnerability. Some companies are putting patches and updates on hold as their resources are strained with the new work from home culture. They may be looking to install features that would provide stability from the increased external traffic of the remote workforce. However, this interruption in patching will leave vulnerabilities on enterprise endpoints open to be exploited by malicious actors.
In order to define what specific risk scenarios are related to this vulnerability, the analyst would start by determining what item of value is of the most concern. This could range from a specific workstation with access to high value information, such as your head of sales, a particular database, or even a specific process that would be impacted from an unpatched endpoint vulnerability. In this instance let’s say the most probable and biggest concern is a particular database accessed by all employees.
Scenario:
Asset: Key database containing sensitive information
Threat: External Actor (Cyber Criminal)
Effect: Confidentiality
Method: Exploiting an unpatched endpoint vulnerability & targeting the database
Since we’ve defined the scenario, the analysts would then talk to SMEs within the organization or use the knowledge they already have to determine the magnitude (associated cost) by looking at the six forms of loss (from the FAIR model) that directly affect the organization or indirectly affect customers or other stakeholders, if this incident were to occur.
Top Risks Reporting and Risk Assessment for Work from Home Cybersecurity
This same approach can be taken to clearly define each of the concerns facing the organization. Then, using the Rapid Risk Assessment capability of the RiskLens platform, in minutes per scenario, the company can determine what the costs would be if each event were to occur. By doing so, they can quickly determine what the top risks are to the organization as employees work from home and begin to address accordingly.
The results of each individual risk scenario will include the most likely cost if this event occurred in the next year, including the 10 th and 90 th percentiles, to give a range of values. This annualized loss exposure can then be used to show decision makers what the loss exposure would be and how best to prioritize security investments.
Additionally, these scenarios can be aggregated to calculate a total loss exposure. The chart below is a loss exceedance curve showing the aggregate annualized loss exposure (ALE) of all the WFH risks from the list above. The values on the curve show the range of exposure the organization is exposed to in a given year from WFH-related scenarios.
