Imagine you're the security manager of a city where each citizen needs access to various areas to live and work. You've issued keycards based on roles, but you've recently discovered that some citizens can gain entry to sensitive locations—like the bank vault—through a combination of their legitimate access rights.

Your current security system, like your legacy IGA system, can only see individual access rights, missing the dangerous combinations that create vulnerabilities.

Now, picture upgrading to a more sophisticated security system that analyzes the entire' chess board' of access. This system identifies risky combinations, adapts, and offers safer alternatives while ensuring citizens can still access what they need. 

This scenario illustrates a policy-based approach to provisioning. It's about understanding the complicated interaction of access rights and controlling the dangers, not about locking things down. Just as this hypothetical security system would improve city security, a multi-point access governance solution can change your ability to prevent toxic combinations of entitlements, balancing security with efficiency in your complex digital processes.

What Are Toxic Combinations?

Toxic combinations of entitlements are a mix of access rights that provide users with excessive privileges, potentially threatening your security and controls. These combinations can arise when multiple vulnerabilities converge within a single user identity, exponentially increasing the risk of a security breach.

Existing IGA systems fail to address the complex issue of toxic combinations. These dated systems focus on individual access rights rather than the cumulative effect of multiple entitlements, leaving you vulnerable to sophisticated threats.

Understanding Toxic Combinations of Entitlements

Users are granted toxic combinations when they are given multiple access rights that, when put together, make a dangerous level of privilege. Some examples are:

• A user who has both front-end "write" privileges and back-end system administration rights, which allows them to manipulate financial data and cover their tracks.

• A user who has the ability to create new vendors and issue payments, enabling fraud through fictitious companies.

• A user who can cause financial misstatement by entering an inaccurate journal entry without approval to overstate assets or understate liabilities.

Toxic combinations of entitlements can have serious consequences. They open the door to all sorts of trouble - from data breaches and fraud to control failures and damaged reputations. These toxic combinations could land you in hot water with the law. For example, violating the Sarbanes-Oxley Act means hefty fines or even legal action. It's not just about following rules; it's about protecting your company's integrity and bottom line.

The Need for Fine-Grained Multi-Point Security

The digital world presents organizations with increasingly complex security challenges. To protect sensitive data and systems, it's necessary to implement a thorough security approach at various points in your IT infrastructure. This multi-point security strategy creates a more comprehensive defense against breaches.

By applying security controls at different levels—such as the network, application, and data layers—you build a stronger defense system. If one layer is compromised, others can still help protect your assets. Fine-grained security allows you to make access decisions based on various factors, including user identity, device type, location, time, and behavior patterns. This contextual awareness helps enhance security by adapting to different scenarios.

With fine-grained controls, you can protect data at a pinpoint level, such as individual database fields or specific sections within documents. This ensures that sensitive information stays secure even when broader access is granted. Additionally, multi-point security enables you to create adaptive policies that can change based on risk assessments, allowing your security measures to evolve alongside emerging threats.

These fine-grained controls also simplify compliance with regulatory requirements by allowing you to implement precise access measures. By limiting access at multiple points and levels, you reduce your attack surface.

While setting up fine-grained multi-point security does require careful planning and the right solution, the benefits of enhanced protection, flexibility, and control effectiveness are worth the effort. As part of a comprehensive access governance strategy, this approach lays a solid foundation for managing security effectively.

Key Components of Policy-Based Provisioning

Access Request and Approval Workflows

With policy-based provisioning, you can streamline your access management through automated workflows. This includes:

• Automated low-risk batch approvals to lighten your manual workload.
• Multi-level approval processes for more sensitive access requests, ensuring that the right people are involved in the decision-making.
• Risk-aware access decisions that consider predefined policies to enhance security.

Segregation of Duties (SoD) Enforcement

Enforcing effective SoD policies is important for maintaining security and compliance within your organization:

• You can conduct proactive evaluations of SoD policies to prevent conflicts of interest.
• Automated systems can help detect and prevent toxic combinations of access rights, keeping your operations secure.

Provisioning and De-provisioning

Automated processes make it easier for you to manage access accurately and on time:

• Make policy-based access decisions based on user attributes and changing circumstances.
• Use automated adjustments to access rights based on evolving risks or shifts in user roles, ensuring that permissions are always appropriate.

Fine-Grained Multi-Point Security

This aspect is vital for a comprehensive security strategy:

• Consider the security context across multiple systems and entry points to protect your organization effectively.
• Be aware of the potential for toxic combinations of access across different entry points, as securing just one system isn’t enough if others remain vulnerable.

By including these elements in your access governance framework, you can develop a stronger and more flexible approach to managing user access. This not only strengthens your security but also increases efficiency in managing complex IT environments.

As you've seen, managing access rights is no small task. The risk of toxic combinations of entitlements is real and can pose serious threats to your organization's security and control efforts. By implementing fine-grained, policy-based provisioning and regular fine-grained access reviews, you're not just ticking boxes – you're building a full defense against breaches and insider threats.

Remember, it's not just about who has access to what but also about how different access rights interact across your systems. Those seemingly harmless combinations of entitlements could be a ticking time bomb if left unchecked. By staying sharp and leveraging the right tools, you can keep your organization's assets safe and your auditors happy.
