Mitigating Insider Threats: Enhancing User Provisioning and Access Control in the NIS2/DORA Era

The Impact of Insider Threats on Organizations

Insider threats can be described as any malicious or accidental action exhibiting the intention, privilege, and opportunity of a user who is legally allowed to access an organization’s systems and information, and the consequences can be disastrous. Such risks are loss or theft of data, theft of ideas, acts of vandalism, and fraud and all of them are very expensive.

To some extent, the negative effect of insider threats can be described as catastrophic. The studies carried out in the recent past reveal that the average cost of an insider affair is $15. 38 million of people, and the financial services and healthcare industries are the most affected ones. These threats can also be very comprehensive because the functioning of an organization, it’s image and the confidence of customers and investors can be at risk.

Common Insider Threats

Insider threats can take many forms, but some of the most common include:

• Malicious Insiders: These are people who deliberately use their position in any organization’s structures, and information to cheat or cause harm on others. This can be in the form of theft as in embezzlement of important data, damaging important equipment or indulging in fraudulent activities.
• Negligent Insiders: These are people who either through lack of proper care or because they have not been taught how not to endanger an organization, do so. It can be as follows; being deceived into parting with personal information for instance in phishing scams, not using strong passwords or not safeguarding crucial documents.

• Compromised Insiders: These are people whose credentials have been stolen or procured in any other unlawful way by a threat actor in an attempt to gain access into an organization’s applications and information systems.

Dealing with these types of insider threats requires the approach that is a combination of user management and access control and security training of the employees.

User Provisioning: A Key Element in Mitigating Insider Threats

User provisioning can be defined as the process of initializing, changing, and deactivating user accounts and the level of access in an organization’s information technology environment. User provisioning allows the management to guarantee that only the people who should be able to perform certain tasks can access the resources they need to complete them.

Another crucial concept when it comes to user provisioning is the principle of least privilege, which implies that users should possess the minimum level of privileges necessary to perform their tasks. If this principle is followed to the letter, then it becomes possible to avoid the everyday situations of misuse or abuse of privileged access.

User provisioning should also incorporate other IAM practices such as MFA, reviewing users’ access, and even the removal of access privileges when the user is transferred to another department or dismissed from the company. These help in ensuring that the access granted to users is well monitored and restricted from cases such as hacking.

Access Control: Strengthening Security in the Midst of NIS2/DORA

The introduction of NIS2 and DORA legislation in the EU has changed the focus towards the necessity of stringent access control against internal threats.

NIS2 is supposed to enhance the organizations related to critical infrastructure by increasing the requirements to access control, incident notification, and risk evaluation, while DORA is designed to enhance the cybersecurity of organizations of financial services. Such regulations call for implementation of measures such as the RBAC and ABAC that limit the users’ access to resources only to those they are supposed to.

To comply with these regulations and effectively mitigate insider threats, organizations must adopt a comprehensive approach to access control that includes the following elements:

• Identity and Access Management (IAM): These are strong IAM mechanisms that would help in the right identification of the user, and the assignment of appropriate rights to the account based on the principle of least privilege.
• Privileged Access Management (PAM): Other measures that can be applied to mitigate the problem of privileged account management which is targeted by insiders.
• Continuous Access Evaluation: The frequency at which the access provided to the user for the purpose of maintaining the security standards of the organization as well as the working duties of the user.
• Audit and Reporting: Logging and reporting that will enable tracking of the activities of the users and any attempt at violation of the security.

By these measures of access control, organizations can improve the security of their systems and consequently, mitigate the rising threat of insider threats.

User Management and Access Control: What Works

To effectively mitigate insider threats, organizations should adopt the following best practices for user provisioning and access control:

• Implement the Principle of Least Privilege: Restrict access rights to the minimum as required by the user’s position and conduct periodic checks on the rights and modify them if needed.
• Automate User Provisioning: Minimise the chance of errors by automating the management of users through the tools and the workflows that will enable creation of accounts, modification, and deletion of accounts.
• Enforce Multi-Factor Authentication: Ensure that the users type in other details such as a code that is provided once or a biometric feature to access the important systems and information.
• Regularly Review and Audit Access: It should also be periodically updated like reviewing the user’s access levels and privileges and making the needed changes like revoking or changing the access level if the user has been transferred to another position or has left the organization.
• Provide Comprehensive Employee Training: Educate the employees on the various cybersecurity threats, internal threats, and how they can avoid the release of sensitive information and the breach of the organization’s systems.
• Implement Robust Logging and Monitoring: Design proper logging and monitoring procedures through which the activities of users and possible intrusions could be traced.
• Leverage Privileged Access Management (PAM): Implement specific PAM tools to ensure that the right level of access has been granted to the privileged account since they are the focus of insiders.
• Integrate with Enterprise-Wide Security Solutions: It is crucial to ensure that user provisioning and access controls are integrated and synchronized with other technologies and applications such as SIEM and SOAR.

Thus, if these best practices are adopted, it will be easier for an organization to enhance its capacity to address insider threats and protect organizational assets and corporate information.

Conclusion

The field of cybersecurity is vast and constantly developing; however, one of the most difficult problems for organizations of various sizes and types is insider threats. These threats can only be dealt with by proper user provisioning and access controls as a way of protecting an organization’s assets and reputation.

With the new legislation coming into force in the form of NIS2 and DORA, the security of organizations must evolve in order to be compliant and improve their cybersecurity. Therefore, user provisioning and access control best practices should be adopted to mitigate insider threats, improve organizational resilience, and retain customers and stakeholders’ confidence.
