Final answer:
A potential insider threat indicator can be a sudden increase in network traffic or frequent software updates.
Explanation:
A potential insider threat indicator is Option 1: "Sudden increase in network traffic."
Insider threats are security risks that originate from individuals within an organization, such as employees, contractors, or business partners, who have access to sensitive data and systems. A sudden increase in network traffic can be an indicator of an insider threat for several reasons:
1. **Unusual Activity:** A significant and unexplained surge in network traffic can indicate abnormal or unauthorized behavior. An insider with malicious intent may be attempting to exfiltrate data, engage in cyberattacks, or carry out other unauthorized actions that result in increased network activity.
2. **Data Exfiltration:** Insiders looking to steal sensitive information may generate extra traffic as they transfer data from the organization's network to external locations. This can involve uploading data to unauthorized servers or cloud storage.
3. **Uncommon Resource Usage:** Insiders may utilize network resources in ways that differ from their typical behavior. For example, they might access systems or services they don't usually use.
4. **Malicious Activities:** Insider threats can encompass various activities, such as spreading malware, conducting reconnaissance, or exploiting vulnerabilities, all of which can lead to an uptick in network traffic.
To address insider threats, organizations often employ security monitoring and user behavior analytics tools that can help identify unusual or suspicious network traffic patterns. Rapid detection and appropriate response are essential to mitigating the risks associated with insider threats and safeguarding an organization's data and assets.
