Identifying Potential Insider Threat Indicators

---

In today’s interconnected digital world, cybersecurity threats come in many forms. Among these, one of the most insidious is the insider threat. According to recent reports, insider incidents have been on the rise. Consequently, this highlights the need for organizations to be vigilant about potential risks from within their ranks.

What are Potential Insider Threat Indicators?

---

Insider threat indicators are signs or behaviours shown by employees that might hint at a potential risk to your organization’s security. These indicators can be crucial in spotting problems early.

So, what are these threats? They generally fall into two categories: malicious insiders and unintentional insiders.

Understanding Potential Insider Threat Indicators

Malicious insiders are individuals who intentionally aim to cause harm. They might steal data or sabotage systems for personal gain or out of spite. On the other hand, unintentional insiders are those who might accidentally create security issues. They could unknowingly share sensitive information or violate policies without malicious intent.

1. Unusual Access Patterns

One of the most common indicators of an insider threat is unusual access patterns. Consequently, This could include accessing sensitive data outside of regular business hours, from distinctive locations, or accessing more data than is usually required for the employee’s job.

For example, if a sales representative suddenly starts accessing confidential financial information, it could signify they’re planning to commit fraud. Organizations should monitor access patterns and look for any anomalies indicating malicious activity.

2. Unusual Communication Patterns

A change in communication patterns can also signal an insider threat. For example, if an employee suddenly starts communicating with people outside their department or using different communication channels, it could cause concern.
For instance, an employee who typically uses company email might use personal email or messaging apps to communicate with individuals outside the organization. Consequently, This could indicate they are trying to conceal their activities or share sensitive information with an unauthorized party.

3. Increased Use of Removable Media

Did you know that removable media like USB drives, external hard drives, and CDs can pose a serious data security risk for organizations? Consequently, if you notice an employee suddenly using these devices more often, it might indicate they’re trying to move data off-site or share it with unauthorized individuals.
In addition to the increased use of removable media, other indicators include unusual data transfers or file sizes.

4. Increased Data Downloads

Another potential insider threat indicator is an increase in data downloads by an employee. Therefore, This could include downloading large amounts of data, downloading data from unusual locations, or downloading data irrelevant to the employee’s job duties.
For example, an employee who typically downloads small files for their work might suddenly start downloading large files, including sensitive information or information unrelated to their job functions. Finally, This could indicate they are trying to exfiltrate data from the organization.

5. Suspicious Internet Activity

Suspicious network activity can also be an indicator of an insider threat. Additionally, this could include accessing unauthorized websites, using VPNs or proxies to hide their activity, or connecting to external devices without authorization. For example, if an employee is accessing a website known to host malware, it’s a red flag.
Here’s something to watch out for: frequent visits to websites unrelated to work, browsing sites blocked by the organization’s security policies, or accessing sites linked to cybercrime or espionage. Consequently, these behaviours could signal potential insider threats.

6. Changes in Personal Finances or Lifestyle

While not always directly related to their work, changes in an employee’s finances or lifestyle, like a sudden increase in wealth or extravagant spending, could indicate insider threat activity. Therefore, This is especially relevant if the individual can access sensitive information or financial systems.

7. Physical Security Breaches

Physical security breaches, like unauthorized access to secure areas or equipment, can also signal potential insider threats. For example, an employee who is observed entering a restricted area without authorization or an employee who is found tampering with security equipment could be attempting to gain access to sensitive information or systems.
Additionally, it is essential to be aware of employees who appear to be taking pictures or videos of confidential information or systems. As a result, This could indicate that they are attempting to steal or share sensitive data.

8. Employee Discontent or Frustration

Disgruntled or frustrated employees can pose a serious insider threat risk. Hence, it’s crucial to address employee grievances and concerns promptly to prevent them from escalating into malicious activities. Similarly, Signs of discontent may include complaints about management, feelings of unfair treatment, or stress related to work.

This doesn’t mean that every unhappy employee is a potential threat. However, it does highlight the importance of creating a positive and supportive work environment that fosters open communication and addresses employee concerns. As a result, This can help mitigate the risk of employees turning to malicious activities.

9. Changes in User Behaviour as Potential Insider Threat Indicators

One of the most apparent signs of a potential insider threat is a change in an employee’s behaviour. This could include anything from a sudden increase in login attempts during off-hours to an unusual data access pattern. The impact of such threats can be significant, underscoring the importance of vigilance.
For example, an employee who typically only accesses their files might suddenly start accessing files belonging to other departments or groups. This could indicate that the employee is trying to gain unauthorized access to sensitive information or prepare for an upcoming breach. Your vigilance is key in preventing such unauthorized access.

10. Lack of Security Awareness Training

Your staff’s significant lack of awareness of security risks and best practices can contribute to insider threats. Furthermore, employees might not grasp the importance of security measures or be unaware of the potential consequences of their actions.
Ensure your employees receive regular, comprehensive security awareness training to mitigate this. Additionally, this should encompass training on how to identify and report suspicious activity, how to protect sensitive data, and how to avoid common security risks.

Organizations must vigilantly identify and mitigate insider threats. Moreover, being aware of the top 10 indicators—such as unusual access and changes in behavior or bypassing security controls—helps protect against insider risks. While noticing one indicator doesn’t necessarily indicate a threat, it’s crucial to investigate any concerns.
