As we near the end of Cybersecurity Awareness Month, it’s crucial to spotlight a pressing concern in the digital age: insider threats.

These threats, whether malicious or accidental, are on the rise, underscoring the need for robust security measures and vigilant oversight. 

Understanding why insider threats are increasing and how businesses can combat these risks is essential for protecting sensitive information and maintaining operational integrity.

The Rising Tide of Insider Threats

Insider threats refer to risks posed by individuals within an organization who have access to its systems and data. These threats can be categorized into two main types: malicious and accidental.

Malicious Insider Threats

These involve individuals who deliberately seek to harm an organization. Their motives can range from financial gain to personal grievances. Malicious insiders often exploit their access to data and systems to commit fraud, steal intellectual property, or sabotage operations.

Accidental Insider Threats

These are typically the result of human error or negligence. Employees might inadvertently expose sensitive information through poor security practices, such as using weak passwords, falling for phishing scams, or mishandling confidential data.

A recent study found that insider threats have increased by 47% since 2018, while the cost of these threats has increased by 31% in the same time span.

Why Are Insider Threats Increasing?

Increased Access

The modern workplace often involves remote work and cloud-based systems, expanding the scope of data access. Employees have more entry points to sensitive information, increasing the likelihood of both accidental and malicious breaches.

Complexity of IT Environments

As technology evolves, so do the systems and networks that organizations use. The complexity of these environments can lead to gaps in security, which insiders might exploit either intentionally or unintentionally.

Growing Dissatisfaction

Employee dissatisfaction and disengagement can lead to malicious insider threats. Individuals who feel undervalued or mistreated may act out by compromising their employer’s security.

Lack of Training

Many employees lack adequate training on cybersecurity best practices. Without proper education, they may unknowingly contribute to security vulnerabilities.

Why Businesses Underestimate Insider Threats

Despite the growing awareness of cybersecurity threats, many businesses continue to underestimate the risk posed by insiders. Several reasons contribute to this underestimation:

Focus on External Threats

Organizations often prioritize defense against external cyberattacks, such as hacking and malware, believing that insiders are less likely to pose a threat. This external focus can lead to insufficient attention and resources allocated to insider threat prevention.

Overconfidence in Security Measures:

Some businesses assume that their existing security measures, such as firewalls and antivirus software, are sufficient to protect against all types of threats, including insider risks. This overconfidence can result in neglecting the need for specific controls to address insider threats.

Underestimation of Human Behaviour

Employee dissatisfaction and disengagement can lead to malicious insider threats. Individuals who feel undervalued or mistreated may act out by compromising their employer’s security.

Lack of Visibility

Without comprehensive monitoring and analysis, it can be challenging for businesses to detect and understand insider threats. Limited visibility into user activity and data access makes it difficult to identify potential risks and implement effective countermeasures.

Implementing Controls to Prevent Insider Threats

To mitigate the risk of insider threats, businesses should implement a comprehensive security strategy that includes the following controls:

Access Management

Implement strict access controls and regularly review permissions. Ensure that employees only have access to the data and systems necessary for their roles. Use multi-factor authentication to enhance security.

Employee Training

Regularly train employees on cybersecurity best practices, including recognizing phishing attempts. Training should be ongoing to address new threats and reinforce safe behaviours.

Monitoring and Detection

Employ advanced monitoring tools to detect unusual or suspicious activities. Set up alerts for unusual behaviours, such as accessing large volumes of data or logging in from unusual locations. 

Data Encryption

Encrypt sensitive data both at rest and in transit. This helps protect information from unauthorized access, even if an insider attempts to extract or manipulate it.

Incident Response Plan

Develop and maintain a robust incident response plan. Ensure that it includes procedures for addressing insider threats and that employees know how to report suspicious activities.

Regular Audits

Conduct regular security audits to identify and address vulnerabilities. These audits should include reviewing access logs, permissions, and security policies.

Secure Off-Boarding

Employees might develop a sense of ownership over the data they handled while employed, even if they leave the company amicably. It is crucial to remind departing employees of the company’s data security policies and to alert IT and security teams about an employee’s upcoming departure.

How a Managed Service Provider Can Help

MSPs play a vital role in enhancing cybersecurity and mitigating insider threats. Here’s how an MSP can assist:

Incident Response and Recovery

In the event of a security breach, an MSP can help manage the incident response, including identifying the source of the threat, containing the breach, and recovering lost data.

Ongoing Training and Support

MSPs can provide continuous cybersecurity training for employees and keep organizations updated on the latest threats and best practices.

Compliance and Risk Management

MSPs assist with compliance requirements and risk management strategies, ensuring that businesses adhere to industry standards and regulations.

24/7 Monitoring

Many MSPs offer round-the-clock monitoring services, ensuring that suspicious activities are detected and addressed promptly. This constant vigilance is crucial for identifying and mitigating insider threats.

Expertise and Resources

MSPs have specialized knowledge and resources to implement advanced security measures. They can deploy sophisticated monitoring tools, conduct vulnerability assessments, and manage complex security infrastructure.

As Cybersecurity Awareness Month highlights the importance of safeguarding digital assets, addressing insider threats remains a critical component of any security strategy. The rise of both malicious and accidental insider threats calls for proactive measures, including robust access controls, comprehensive employee training, and vigilant monitoring.
