Regain control through effective data governance to secure your sensitive information

Do you really control who has access to your company’s sensitive data? Think about it! Every day, your financial decisions rely on the integrity and protection of your systems. But do you have an overview of who is authorized to modify accounting documents, add payment beneficiaries, or view your banking information? Before even addressing access management, it is essential to understand the strategic challenges of cybersecurity for Quebec businesses.

For example, does your accounting technician still have access to financial data even though their role no longer requires it? The reality is that, in many organizations, access privileges accumulate over time, often without real supervision. Can a former employee still log in to your IT systems? Did an intern retain their access after their departure?

These hidden vulnerabilities threaten not only your financial security but also your regulatory compliance with Law 25. To detect these flaws and act quickly, it is highly recommended to conduct a complete IT audit of your access and systems.

The role of access management in your data governance

Access control is an integral part of a data governance strategy aimed at establishing standards, processes, and solutions that ensure the security, integrity, and accessibility of your critical information. This strategy determines who can view, modify, or share confidential data within your company.

By assigning each user, supplier, or partner only the permissions essential to their functions, access control minimizes the risk of unauthorized intrusions and guarantees your regulatory compliance, particularly with Law 25 obligations.

The importance of an access control policy for your IT protection

Rigorous access management is an essential pillar of your governance and cybersecurity. It protects your organization and ensures compliance. Well-structured, it protects your company’s profitability; however, if neglected, it also exposes your SME to major risks such as:

1. Financial impacts: data theft, internal fraud, high recovery costs.
2. Legal consequences: penalties for non-compliance with Law 25.
3. Operational risk: service interruptions and loss of productivity.
4. Reputational damage: data leaks, degradation of the company’s image, loss of customer and employee trust.

Reducing these risks does not rely solely on cybersecurity tools. It is essential to adopt clear practices tailored to your business.

Once access is inventoried, you can implement a tailored IT protection strategy to limit risks and oversee authorizations.

Access management in 4 effective steps

Step 1: Identify critical assets

Identifying critical assets is the first step in integrating a strong access management process. This overview allows you to identify the most critical elements and effectively structure your security measures.

Failing to perform this assessment is like managing your company’s finances without knowing your income and expenses. You are making decisions blindly, with the risk of underestimating vulnerabilities and leaving access unsecured.

To ensure the security of your data, start by identifying your essential assets:

• Your human assets: your employees, particularly those with access to sensitive information, such as financial statements or commercial contracts.
• Your physical assets: such as servers, laptops, and cell phones that have access to company data.
• Your financial assets: for example, your banking and tax data.
• Your informational assets: this refers to customer databases, intellectual property, business strategies, etc.

To conduct an effective inventory of your assets, it is essential to adapt it to the specific needs of your business.

For example, a manufacturing company should prioritize its production systems and connected equipment, while a service company will focus on its customer and financial data.

An in-depth analysis is necessary to leave nothing to chance and identify critical assets, including those often forgotten, such as inactive email boxes, external hard drives, or access given to subcontractors. These are among the critical cybersecurity challenges we address here.

Step 2: Define who has access to critical assets

After identifying your company’s critical assets, it is essential to know exactly who can access them. That is, who can view, modify, or share your company’s sensitive information? Without this overview of your assets, access accumulates and quickly becomes uncontrollable, thereby increasing the risks of error, leaks, or data misuse.

During this step, it is not uncommon to discover obsolete or excessive access.

For example, during a review for a client, our experts found that an accounting technician could access the HR department’s SharePoint, where all employees’ social insurance numbers were stored. This was a major risk in terms of compliance and IT security. Fortunately, during the access inventory, we were able to detect this flaw.

To ensure rigorous access monitoring, we suggest identity and access management tools, such as Microsoft Identity Manager. These solutions offer unified management of system access rights, ensuring appropriate permissions for each user.

Step 3: Strengthen the security of sensitive data

After identifying your company’s critical assets and determining who has access to them, it is time to implement the access review strategy. This step is essential to ensure that each user has only the permissions necessary for their role, while ensuring that these access rights are adjusted over time. Access management is only one part of a whole. It is essential to adopt a multi-layered approach to cybersecurity to ensure maximum protection.

Concretely, this step allows you to:

• Define roles and access levels. 
• Establish clear procedures for consistent and secure management. 
• Implement a validation process for new access. 

Let’s return to our client’s example. After discovering that certain unauthorized users had access to the company’s HR data, we were able to implement a review strategy. This approach allowed us to correct inappropriate permissions and establish a rigorous validation process for new access.

For our experts, permission management tools like Microsoft Entra ID are essential for effective data governance. Among other things, they allow for the detection of excessive permissions, the identification of risks before they become critical, and the integration of permission governance strategies.

But effective access governance alone is not enough to protect your business. To ensure optimal security, it is essential to adopt a multi-layered approach, combining identity management, proactive monitoring, and advanced protection against cyber threats, among others.

Step 4: Implement a regular monitoring process within the data governance framework

Effective access management is not limited to establishing an access governance policy. It is fully part of a global data governance approach, which requires constant monitoring and adjustments. Organizations evolve, employees change roles, new risks emerge… and without sustained vigilance, superfluous or dangerous access rights multiply.

To avoid these deviations, we recommend establishing regular monitoring of access to your data to strengthen your security. Daily monitoring ensures rigorous access management, thereby reducing the risk of unauthorized intrusions and compliance failures.

To ensure up-to-date access management, we suggest establishing:

• A partial review every 90 days to check for dormant access or restrictions that need to be modified.
• A full review every year to ensure that all permissions still correspond to the current organization and security standards.

Why this frequency?

Controls that are too far apart (for example, every 4-5 years) can lead to higher expenses and expose vulnerabilities that could be avoided through regular monitoring. Continuous monitoring reduces risks, ensures rigorous access management, and optimizes costs.

To ensure optimal monitoring, we deploy cutting-edge solutions, such as Microsoft Entra ID and many other solutions. These tools allow for the centralization, monitoring, and securing of access management in your company. Combined with our personalized approach, these solutions guarantee a strong data governance process perfectly aligned with your business needs. This strategy not only strengthens data protection but also minimizes the financial and operational impacts associated with uncontrolled access.
