Introduction to Insider Threats
Insider threats severely threaten organizations via in-system access and concealed data. What is an Insider threat? Insider threats are introduced by workers, contractors, or business companions with authorized entry and utilize it knowingly or unwittingly. Understanding Insider threats contain full information about their categories, associated hazards, and alleviations.
Types of Insider Threats
Insider threats could be categorized under three broad classifications:
Malicious Insiders
They act deliberately to harm the company by stealing data, breaching the systems, or leaking confidential information. Money, personal agendas of revenge, or business spying are their motivations.
Negligent Insiders
Employees unknowingly introduce security threats because they are unaware, do not have good cyber security practices, or do not follow company policies. Blindly opening unsolicited e-mail, weak passwords, or mishandling confidential information are a few of them.
Compromised Insiders
They disclose their credentials to third-party attackers who in turn abuse their privileges to breach the company. Compromised insiders do not even realize they are exposed until it is too late.

- Repeated policy violations and non-adherence
- Irked employee attitude or suspicious monetary benefit

- Security Awareness Training: Educate employees to detect and notify security breaches.
- Incident Response Plan: Develop responses to handle insider threat incidents effectively.
- Behavioral Analytics: Employ AI-powered software to detect unusual user behavior patterns.
Role of Technology in Insider Threat Detection
Emerging technologies provide detection and prevention of insider threats:
- Data Loss Prevention (DLP) Systems: Restrict unauthorized leak of confidential data.
- SIEM (Security Information and Event Management): Monitor security logs in real-time.
- User Behavior Analytics (UBA): Detect malicious activity or Understanding insider threats.
- Identity and Access Management (IAM): Offer secure identity and access management.
Organizational Best Practices
Organizations can become more resistant to insider attacks by:
- Performing regular security scans so that they can identify vulnerabilities
- Having zero-trust security architectures to limit internal access
- Encouraging a security-aware culture through regular training
- Having Zero-Day whistleblower procedures for reporting suspicious activity
- Having multifactor authentication (MFA) to provide an added layer of login security
Examples of Insider Threat Incidents
Edward Snowden (NSA Leak): A former NSA contractor divulged classified information, showing government surveillance methods.
Tesla Data Theft (2018): A dissatisfied employee pilfered confidential data and unauthorized code modifications.
Capital One Breach (2019): A former employee accessed sensitive customer information through a compromised server.
