Harassment and Discrimination

A subject engages in unauthorized conduct that amounts to harassment or discriminatory behavior within the workplace, targeting individuals or groups based on protected characteristics, such as race, gender, religion, or other personal attributes. Incidents of harassment and discrimination may expose the organization to legal risks, potential reputational damage, and regulatory penalties. Additionally, individuals affected by such behavior may be at higher risk of retaliating or disengaging from their work, potentially leading to further insider risks.

Prevention

ID Name Description
PV039Employee Mental Health & Support Program

Offering mental health support and conflict resolution programs to
help employees identify and report manipulative behavior in the
workplace

PV042Employee Vulnerability Support Program

A structured program, including a helpline or other reporting mechanism, designed to assist employees who feel vulnerable, whether due to personal issues, coercion, or extortion. This process allows employees to confidentially raise concerns with trusted teams, such as Human Resources or other qualified professionals. In some cases, it may be appropriate to discreetly share this information with trusted individuals within the Insider Risk Management Program to help prevent and detect insider threats while also providing necessary support to the employee.

PV022Internal Whistleblowing

Provide a process for all staff members to report concerning and/or suspicious behaviour to the organization's security team for review. An internal whistleblowing process should take into consideration the privacy of the reporter and the subject(s) of the report, with specific regard to safeguarding against reprisals against reporters.

PV001No Ready System-Level Mitigation

This section cannot be readily mitigated at a system level with preventive controls since it is based on the abuse of fundamental features of the system.

Detection

ID Name Description
DT047Agent Capable of User Behaviour Analytics

An agent capable of User Behaviour Analytics (UBA) is a software agent installed on organizational endpoints (such as laptops). Typically, User Activity Monitoring agents are only deployed on endpoints where a human user is expected to conduct the activity.

 

The User Behaviour Analytics agent will typically record Operating System, application, and network activity occurring on an endpoint, focusing on activity that is or can be conducted by a human user. Typically, User Behaviour Analytics platforms operate in an agent/server model where activity logs are sent to a server for automatic analysis. In the case of User Behaviour Analytics, this analysis will typically be conducted against a baseline that has previously been established.

 

A User Behaviour Analytic platform will typically conduct a period of ‘baselining’ when the platform is first installed. This baselining period establishes the normal behavior parameters for an organization’s users, which are used to train a Machine Learning (ML) model. This ML model can then be later used to automatically identify activity that is predicted to be an anomaly, which is hoped to surface user behavior that is undesirable, risky, or malicious.

 

Other platforms providing related functionality are frequently referred to as User Activity Monitoring (UAM) platforms.

DT040Microsoft Exchange Message Trace

Message trace is a feature within Exchange that permits the ability to identify inbound and outbound emails within the organization.

This can be used to see which mailboxes have sent or received emails, the time, the subject line, and recipients.

DT094Microsoft Purview Audit Search

Microsoft's Purview portal has a feature named Audit that permits access to critical audit log event data to gain insight and further investigate user activities. This can be used to investigate activity from a range of Microsoft services, such as SharePoint, OneDrive, and Outlook. Searches can be scoped to a specific timeframe, user account, and platform using the extensive filters available. 

DT049Social Media Monitoring

Social Media Monitoring refers to monitoring social media interactions to identify organizational risks, such as employees disclosing confidential information and making statements that could harm the organization (either directly or through an employment association).
