Insider threats are the intentional or unintentional actions of employees, contractors, or third-party vendors who put an organization’s data and systems at risk. Insider threats are a significant concern for businesses of all sizes and industries. Without the right policies, procedures, and technology in place, any organization can fall victim to an insider attack, potentially resulting in significant damage to brand reputation, financial losses, and business continuity disruptions.
What Are Insider Threat Indicators?
Insider threat indicators are the signs that an organization must look out for that suggest that malicious activity is taking place within their environment. Such indicators may include excessive logging onto a system, or searching for sensitive information that is outside of their work requirements. Additionally, changes in an individual’s behavior, such as isolation from colleagues, sudden financial stress, or other personal issues, can also indicate a potential insider threat. Organizations must continuously monitor their systems and user behavior to quickly identify potential insider threats.
Possible Motives of Insider Attackers
Below are the most common motives behind insider threats:
Financial Gain
One of the most common motives for insider threats is financial gain. Employees may engage in fraudulent activities such as embezzlement, theft, or unauthorized trading to benefit financially. They might exploit their knowledge of the organization’s financial systems, access sensitive data, or manipulate financial transactions for personal enrichment.
Revenge or Resentment
Disgruntled employees may seek revenge or express resentment towards their organization, colleagues, or superiors. Motivated by personal grievances, such as perceived mistreatment, termination, or dissatisfaction, they may intentionally sabotage systems, delete critical data, or disrupt operations to cause harm.
Espionage or Intellectual Property Theft
Some insiders may be driven by espionage or the desire to steal intellectual property. They may have affiliations with competitors, foreign governments, or other malicious entities. These individuals may try to gain unauthorized access to confidential information, trade secrets, or research and development data to sell or use for personal or external gains.
Ideology or Activism
In certain cases, insiders may have ideological or activist motives. They may misuse their access to disrupt operations, leak sensitive information to the public, or deface websites as a form of protest against their organization’s practices, policies, or industry. These individuals may act out of a sense of moral conviction or a desire for social or political change.
Carelessness or Negligence
Not all insider threats are intentional or malicious. Some incidents occur due to carelessness, negligence, or lack of awareness among employees. Inadvertently, they may fall victim to phishing attacks, accidentally disclose sensitive information, or fail to follow security protocols, leading to data breaches or system vulnerabilities.
Top Insider Threat Indicators
Below are some of the most common indicators of insider threats:
1. Unusual Network Activity
Unusual network activity is a common indicator of an insider threat. An employee who is preparing to steal data or engage in other malicious activities may access resources that he or she has never used before or access files that are out of his or her usual working hours. Monitoring network activity can help organizations detect such behavior.
2. Accessing Unauthorized Information
Insiders with malicious intent may try to access information that they are not authorized to view or download. This could be sensitive/confidential data or proprietary information, such as intellectual property. Organizations must monitor such activities closely, and if detected, take swift action to prevent data theft.
3. Changes in Work Habits
A change in work habits can be a sign of an insider threat. An employee who is typically punctual, but suddenly starts arriving late or leaving early might be planning a data breach. Similarly, an employee who suddenly stops showing up for meetings or ceases collaborating with co-workers and supervisors could be a cause for concern.
4. High Level of Access Privileges
Another red flag is individuals who have high-level access privileges within the organization. Not only does this increase the chances of data theft, but it also increases the severity of the risk. Organizations should monitor and limit access privileges to reduce the likelihood of insider wrongdoing.
5. Active Job Search
An insider who is actively seeking new employment may be planning to steal organizational data or intellectual property before departing. Without causing any privacy violations, organizations should keep an eye out for employees actively seeking employment elsewhere.
6. Recent Security Violations
Employees who have recently been disciplined for security violations are also much more likely to commit malicious activities or attempt to steal information. Organizations must monitor these employees to mitigate the potential risk of future security violations.
7. Financial Difficulties
Insiders who are experiencing financial difficulties are more likely to steal data to sell to third parties or commit fraudulent activities. Organizations should look out for behavior that may indicate that an employee is experiencing financial difficulties, without violating their privacy.
8. Use of Unauthorized Software
When employees download and use software without proper authorization, they are breaking company policies and potentially compromising the security of the organization. This could include malware or other malicious software that could infect the company’s network, or software that is not secure and could allow for unauthorized access to sensitive information.
