Payment Card Data Leakage
A subject with access to payment environments or transactional data may deliberately or inadvertently leak sensitive payment card information. Payment Card Data Leakage refers to the unauthorized exposure, transmission, or exfiltration of data governed by the Payment Card Industry Data Security Standard (PCI DSS). This includes both Cardholder Data (CHD)—such as the Primary Account Number (PAN), cardholder name, expiration date, and service code—and Sensitive Authentication Data (SAD), which encompasses full track data, card verification values (e.g., CVV2, CVC2, CID), and PIN-related information.
Subjects with privileged, technical, or unsupervised access to point-of-sale systems, payment gateways, backend databases, or log repositories may mishandle or deliberately exfiltrate CHD or SAD. In some scenarios, insiders may exploit access to system-level data stores, intercept transactional payloads, or scrape logs that improperly store SAD in violation of PCI DSS mandates. This may include exporting payment data in plaintext, capturing full card data from logs, or replicating data to unmonitored environments for later retrieval.
Weak controls, such as the absence of data encryption, improper tokenization of PANs, misconfigured retention policies, or lack of field-level access restrictions, can facilitate misuse by insiders. In some cases, access may be shared or escalated informally, bypassing formal entitlement reviews or just-in-time provisioning protocols. These gaps in security can be manipulated by a subject seeking to leak or profit from payment card data.
Insiders may also use legitimate business tools—such as reporting platforms or data exports—to intentionally bypass obfuscation mechanisms or deliver raw payment data to unauthorized recipients. Additionally, compromised service accounts or insider-created backdoors can provide long-term persistence for continued exfiltration of sensitive data.
Data loss involving CHD or SAD often trigger mandatory breach disclosures, regulatory scrutiny, and severe financial penalties. They also pose reputational risks, particularly when data loss undermines consumer trust or payment processing agreements. In high-volume environments, even small-scale leaks can result in widespread exposure of customer data and fraud.
Prevention
ID | Name | Description |
---|---|---|
PV023 | Access Reviews | Routine reviews of user accounts and their associated privileges and permissions should be conducted to identify overly-permissive accounts, or accounts that are no longer required to be active. |
PV052 | Criminal Background Checks | A subject may be required to undergo a criminal background check prior to joining the organization, particularly when the role involves access to sensitive systems, data, or physical spaces. This preventative measure is designed to identify any prior criminal conduct that may present a risk to the organization, indicate a potential for malicious behavior, or conflict with legal, regulatory, or internal policy requirements.
Criminal background checks help assess whether a subject's history includes offenses related to fraud, theft, cybercrime, or breaches of trust—each of which may elevate the insider threat risk. Roles with elevated privileges, access to customer data, financial systems, or classified information are often subject to stricter screening protocols to ensure individuals do not pose undue risk to organizational security or compliance obligations.
This control is especially critical in regulated industries or environments handling national security assets, intellectual property, or financial infrastructure. In such settings, background checks may be embedded within broader personnel vetting procedures, such as security clearances or workforce integrity programs.
Where appropriate, periodic re-screening or risk-based follow-up checks—triggered by role changes or concerning behavior—can strengthen an organization’s ability to detect emerging threats over time. When implemented consistently, background checks can serve as both a deterrent and a proactive defense against insider threat activity. |
PV020 | Data Loss Prevention Solution | A Data Loss Prevention (DLP) solution refers to policies, technologies, and controls that prevent the accidental and/or deliberate loss, misuse, or theft of data by members of an organization. Typically, DLP technology would take the form of a software agent installed on organization endpoints (such as laptops and servers).
Typical DLP technology will alert on the potential loss of data, or activity which might indicate the potential for data loss. A DLP technology may also provide automated responses to prevent data loss on a device. |
PV051 | Employment Reference Checks | An individual’s prior employment history may be verified through formal reference checks conducted prior to their onboarding with the organization. This process aims to validate key aspects of the subject’s professional background, including dates of employment, job titles, responsibilities, and performance, as well as behavioral or conduct-related concerns.
Reference checks serve as a critical layer in assessing an individual’s suitability for a given role, particularly where access to sensitive systems, data, or personnel is involved. When conducted thoroughly, this process can help identify discrepancies in a candidate’s reported history, uncover patterns of misconduct, or reveal concerns related to trustworthiness, reliability, or alignment with organizational values.
Employment reference checks are particularly relevant to insider threat prevention when evaluating candidates for positions involving privileged access, managerial authority, or handling of confidential information. These checks may also uncover warning signs such as unexplained departures, disciplinary actions, or documented integrity issues that elevate the risk profile of the individual.
Organizations may perform this function internally or engage trusted third-party screening providers who specialize in pre-employment due diligence. When combined with other vetting measures—such as criminal background checks and social media screening—reference checks contribute to a layered approach to workforce risk management and help mitigate the likelihood of malicious insiders gaining access through misrepresentation or concealment. |
PV012 | End-User Security Awareness Training | Mandatory security awareness training for employees can help them to recognize a range of cyber attacks that they can play a part in preventing or detecting. This can include topics such as phishing, social engineering, and data classification, amongst others. |
PV016 | Enforce a Data Classification Policy | A Data Classification Policy establishes a standard for handling data by setting out criteria for how data should be classified and subsequently managed and secured. A classification can be applied to data in such a way that the classification is recorded in the body of the data (such as a footer in a text document) and/or within the metadata of a file. |
PV003 | Enforce an Acceptable Use Policy | An Acceptable Use Policy (AUP) is a set of rules outlining acceptable and unacceptable uses of an organization's computer systems and network resources. It acts as a deterrent to prevent employees from conducting illegitimate activities by clearly defining expectations, reinforcing legal and ethical standards, establishing accountability, specifying consequences for violations, and promoting education and awareness about security risks. |
PV038 | Insider Threat Awareness Training | Training should equip employees to recognize manipulation tactics, such as social engineering and extortion, that are used to coerce actions and behaviors harmful to the individual and/or the organization. The training should also encourage and guide participants on how to safely report any instances of coercion. |
PV013 | Pre-Employment Background Checks | Background checks should be conducted to ensure whether the information provided by the candidate during the interview process is truthful. This could include employment and educational reference checks, and a criminal background check. Background checks can highlight specific risks, such as a potential for extortion. |
PV046 | Regulation Awareness Training | Regulation Awareness Training equips staff with the knowledge and understanding required to comply with legal, regulatory, and policy obligations relevant to their roles. This includes, but is not limited to, export controls, international sanctions, anti-bribery laws, conflict-of-interest rules, antitrust regulations, and data protection requirements.
The training should be customized according to the specific risks of different roles within the organization, ensuring that employees in high-risk areas—such as legal, procurement, sales, finance, engineering, and senior management—receive in-depth education on how to recognize and avoid behaviors that could lead to regulatory violations. Scenarios that could result in inadvertent or intentional breaches should be addressed, alongside practical advice on how to report concerns and escalate issues.
To accommodate varying learning styles and operational needs, Regulation Awareness Training can be delivered through multiple formats:
By fostering a culture of compliance and accountability, Regulation Awareness Training helps minimize the risk of breaches, whether intentional or accidental, and strengthens the organization’s ability to identify, prevent, and respond to regulatory infringements. |
PV050 | Social Media Screening | A subject’s publicly accessible online presence may be examined prior to, or during, their association with the organization through the application of Open Source Intelligence (OSINT) techniques. This form of screening involves the systematic analysis of publicly available digital content—such as social media profiles, posts, comments, blogs, forums, and shared media—to assess potential risks associated with an individual.
Social media screening is typically conducted to identify indicators of reputational risk, conflicting motives, or behavioral patterns that may suggest the potential for insider threat activity. Content of concern may include public expressions of hostility toward the organization, affiliation with extremist or high-risk groups, or engagement with topics unrelated to the subject's role that could indicate potential misuse of access.
Trusted service providers specializing in OSINT and digital risk intelligence may be engaged to perform this screening on behalf of the organization. These providers use automated tools and analyst-driven review processes to ensure consistent, legally compliant, and policy-aligned assessments of online behavior.
When implemented as part of pre-employment screening or ongoing risk monitoring, social media screening can serve as a proactive measure to detect insider threat indicators early. To be effective and ethical, such programs must follow applicable privacy laws, data protection regulations, and internal governance standards. When responsibly executed, social media screening enhances the organization's ability to identify individuals who may present an elevated risk to information security, personnel safety, or corporate reputation. |
Detection
ID | Name | Description |
---|---|---|
DT046 | Agent Capable of Endpoint Detection and Response | An agent capable of Endpoint Detection and Response (EDR) is a software agent installed on organization endpoints (such as laptops and servers) that (at a minimum) records the Operating System, application, and network activity on an endpoint.
Typically EDR operates in an agent/server model, where agents automatically send logs to a server, where the server correlates those logs based on a rule set. This rule set is then used to surface potential security-related events, that can then be analyzed.
An EDR agent typically also has some form of remote shell capability, where a user of the EDR platform can gain a remote shell session on a target endpoint, for incident response purposes. An EDR agent will typically have the ability to remotely isolate an endpoint, where all network activity is blocked on the target endpoint (other than the network activity required for the EDR platform to operate). |
DT045 | Agent Capable of User Activity Monitoring | An agent capable of User Activity Monitoring (UAM) is a software agent installed on organization 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 Activity Monitoring agent will typically record Operating System, application, and network activity occurring on an endpoint, with a focus on activity that is or can be conducted by a human user. The purpose of this monitoring is to identify undesirable and/or malicious activity being conducted by a human user (in this context, an Insider Threat).
Typical User Activity Monitoring platforms operate in an agent/server model where activity logs are sent to a server for automatic correlation against a rule set. This rule set is used to surface activity that may represent Insider Threat related activity such as capturing screenshots, copying data, compressing files or installing risky software.
Other platforms providing related functionality are frequently referred to as User Behaviour Analytics (UBA) platforms. |
DT047 | Agent 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. |
DT052 | Audit Logging | Audit Logs are records generated by systems and applications to document activities and changes within an environment. They provide an account of events, including user actions, system modifications, and access patterns. |
DT048 | Data Loss Prevention Solution | A Data Loss Prevention (DLP) solution refers to policies, technologies, and controls that prevent the accidental and/or deliberate loss, misuse, or theft of data by members of an organization. Typically, DLP technology would take the form of a software agent installed on organization endpoints (such as laptops and servers).
Typical DLP technology will alert on the potential loss of data, or activity which might indicate the potential for data loss. A DLP technology may also provide automated responses to prevent data loss on a device. |
