Should Your Organization Be Worried About Insider Threats?

Securing and Defending Digital Infrastructure: Essentials Concepts of Cybersecurity

Is your company ready to deal with attacks from within? Although unpleasant, the subject must be posed in today's digital era. While we frequently consider external threats to be the main risk to our organization, the truth is that insiders might be just as dangerous as outsiders. 

Insider threats may have major repercussions, from data breaches to reputational injury, whether from a malicious employee or simply a well-meaning team member who makes a mistake. 

The primary dangers and difficulties that businesses confront, as well as useful advice and tactics for reducing these risks, will all be covered in-depth in this post on insider threats to an organization

What are insider threats?

Internal threats are malicious or careless acts committed by individuals accessing a company's system, data, or network. These behaviors may lead to bodily hurt, financial losses, reputational damages, legal repercussions, and even data breaches. 

Insiders may gain access to computer systems through valid accounts initially granted to them for work-related purposes; nonetheless, these rights might be exploited to harm the company. Insiders frequently thoroughly understand the company's data and intellectual property and the safeguards to secure them. 

The insider will find it simpler to review any security measures they know. The insider is already inside the building, frequently with direct access to the organization's internal network. This eliminates the need for them to breach the firewalls at the organizational perimeter to access data. 

Types of web threats for Organizations in cyber security:

At their most basic level, insider risks originate from within your business. End users with elevated access put your network and data in particular danger. Users may have access controls and special knowledge of internal processes and procedures that allow them to move about without arousing suspicion, making insider threats difficult to defend against. 

As a result, insider assaults frequently aren't discovered until after the breach. Three main types of insider threats to an organization:

  • Unintentional Threat

  • Negligence: By acting negligently, a person with this inside knowledge puts a corporation in danger. Careless insiders are typically aware of security and IT rules but ignore them, endangering the company. A few examples include failing to follow instructions to install security updates and upgrades, allowing someone to "piggyback" past a secured entrance, losing or misplacing a portable storage device with confidential information, and more.
  • Accidental: An insider of this type puts a firm in danger without intending to. Examples include accidentally accepting a virus-filled attachment in a phishing email, entering the wrong email address, and sending a secret business document to a competitor. Another example is improperly destroying private information.
  • Intentional Threats

The term "malicious insider" is frequently used to describe an insider acting maliciously. Threats to harm a company for personal gain or to address a personal issue are known as intentional threats. 

For instance, a perceived lack of acknowledgment (such as a promotion, incentives, or coveted vacation) or firing motivates many insiders to "get even." In a vain attempt to advance their careers, they may leak confidential information, annoying coworkers, sabotage machinery, use violence, or steal confidential information or intellectual property.

  • Other threads

Threats of Collusion - Collusive threats are a subclass of hostile insider threats in which one or more insiders work with an outside threat actor to undermine an organization. In these cases, hackers usually enlist one or more insiders.

Preventing Insider Threats: Best Practices for Businesses

Insider threats are not easy to detect or prevent, as they often exploit insiders' trust and access within the organization. 

However, there are some insider threat prevention strategies that organizations can take to reduce the likelihood and impact of insider threats:

  • Conduct background checks and security clearances for all employees and contractors accessing sensitive data or systems.
  • Provide regular security awareness and training programs for all employees and contractors on phishing prevention, password management, data protection, and policy compliance.
  • Implement a strong identity and access management system that enforces the principle of least privilege, meaning insiders only have access to the minimum amount of data and resources needed to perform their tasks.
  • Monitor and audit user activity and behavior on the network and systems using tools such as user and entity behavior analytics, security information and event management (SIEM), and data loss prevention (DLP).
  • Establish a clear reporting mechanism and a culture of trust and transparency that encourages employees and contractors to report any suspicious or anomalous activity or behavior they observe or experience.
  • Respond quickly and effectively to incidents or alerts involving insider threats using a predefined incident response plan outlining roles, responsibilities, procedures, and communication channels.


Insider risk and cybersecurity are serious and growing challenges for organizations of all sizes and industries. They can cause significant damage to an organization's reputation, finances, operations, and security. 

Therefore, organizations must adopt a proactive and comprehensive approach by combining people, processes, and technology to prevent insider threats. By doing so, organizations can protect their most valuable assets and ensure long-term success.
