When it comes to cyber security, quantum computing has emerged as a double-edged sword in recent years. Not only do quantum computers have the power to process vast amounts of data far faster than traditional computers, they could also lead to advancements in everything from healthcare to artificial intelligence. However, quantum computing poses just as many challenges as it does opportunities.

Why Quantum Computing Is a Game Changer

To understand the threat, you first need to grasp what makes quantum computing so different. Traditional computers use bits to process information, which can exist in a state of either 0 or 1. Quantum computers, however, use qubits, or quantum bits. These can exist in multiple states – meaning they can be a 0 and a 1 at the same time. This allows quantum machines to solve certain complex problems much faster than classical computers ever could.

One of those problems is breaking encryption. Most cyber security solutions rely on cryptographic algorithms for securing data, encrypting communications, and verifying identities. These algorithms rely on mathematical problems that are hard for traditional computers to solve, such as factoring large prime numbers. But a quantum computer, using Shor’s Algorithm, could crack these problems in a fraction of the time.

How Quantum Threatens IAM

At the heart of Identity and Access Management (IAM) is trust – it’s all about making sure only the right people can access the right resources. This trust is established through digital certificates, encrypted credentials, and multi-factor authentication (MFA), which depend on secure encryption protocols. However, quantum computing can undermine this foundation. If quantum computers can break the most widely used cryptographic algorithms, then the mechanisms that protect logins, authenticate users, and secure communications may no longer be effective.

If quantum computers become more widespread, and cyber criminals get their hands on them, Public Key Infrastructure (PKI), a cornerstone of IAM, could be rendered obsolete. This would leave login credentials and identity federation protocols vulnerable. Even encrypted data that’s secure today could be harvested and decrypted in the future – a threat known as ‘store now, decrypt later.’ Even MFA, which often relies on cryptographic key exchanges, would become ineffective if quantum computers can break those algorithms. In short, if businesses fail to prepare now, IAM systems could be left vulnerable.

The Path Forward

The good news is that cyber security experts aren’t standing still. Work is already underway to develop post-quantum cryptography (PQC) – new algorithms that are resistant to quantum attacks. In fact, organisations like the U.S. National Institute of Standards and Technology (NIST) are currently working on standardising quantum-resistant algorithms.

IAM systems of the future will need to integrate these new encryption techniques to offer continued protection. Transitioning to PQC won’t happen overnight, especially given the number of systems, applications, and devices that businesses use today – but as we discussed in a recent episode of our podcast, there are steps you can start taking today.

What Businesses Can Do Now

To prepare for the impact of quantum computing, we recommend businesses should start by conducting a comprehensive assessment of their IAM infrastructure. This involves identifying where any weaknesses may lie, and anything that could be vulnerable to quantum computers. It’s also essential to assess third-party integrations, as many IAM platforms rely on external tools and software. Vendors like CyberArk and LevelBlue can provide insights into how your existing tools are evolving to address quantum threats.

Staying informed is also critical. By monitoring guidance from institutions like NIST and ENISA, you keep your business aligned with emerging best practices. Educating employees and stakeholders across departments will also help them to understand quantum computers and the threats they should be looking out for. Finally, consider looking into solutions that combine classical and quantum-resistant algorithms – these could offer an extra layer of protection as the industry transitions to a post-quantum future.

IAM in a Post-Quantum World

While the arrival of quantum computing may still be years away, its implications for IAM are real. Identity security will need to evolve rapidly in response to these threats. As quantum computers become more advanced, IAM vendors and platforms will likely evolve to offer native support for quantum-resistant algorithms. You can also expect to see new models that don’t rely solely on cryptography but include elements like biometrics, continuous authentication, and context-aware access controls.

Of course, as quantum computing develops, it won’t just be a threat – it could also be a tool. Advanced quantum algorithms might eventually help us to identify fraudulent behaviour faster, or analyse patterns of behaviour more effectively and stop hackers in their tracks. But before we can harness those benefits, we need to prepare and build up our defences.

Quantum computing has the potential to change cyber security in unprecedented ways, and IAM is in the crosshairs. However, by preparing now and following industry developments closely, you can ensure your organisation is ready for the future of identity management. The quantum future may be coming fast, but with the right strategy, you and your IAM systems won’t have to be left behind.

Digital transformation is more than just a buzzword, despite how people might be using it. It’s changed the way modern businesses operate – they’re more interconnected, they use the cloud, and they can adapt quickly to new trends. While there are of course many benefits to this, it’s unfortunately posted a number of cyber security risks – particularly when it comes to managing user identities and access rights. Businesses need to navigate complex environments and protect the data of users on premises as well as in remote locations. Traditional IAM are no longer enough to ensure security, and this is where Identity Governance and Administration (IGA) comes in.

Why Traditional IAM Is Falling Short

To put it simply, IAM is all about verifying user identities and managing their access to your systems and data. However, these solutions don’t always give you the visibility or control that you might need to enforce policies, or meet compliance requirements. With employees often having multiple roles and responsibilities, and moving between departments, it can become harder to keep track of who has access to what.

Without the proper oversight, you can end up with unused accounts and users with too many privileges, both of which are entry points for attackers or internal threats. This can be even more of an issue in cloud or hybrid environments, where there is room for misconfigurations or human error.

The Role of Identity Governance

IGA is a framework that helps organisations control who has access to what, and why. Unlike traditional IAM, which tends to concentrate on authentication and access provisioning, IGA gives users more visibility into – and control over – user identities, throughout their lifecycle. It allows users to regularly review and validate user access), define roles based on job functions, enforce policies to ensure they’re followed, and automate everything from onboarding to deprovisioning of user identities. Not only do these kinds of features help firms ensure that only the right individuals have access to the right resources at the right time, but they also help you  meet regulatory requirements.

The Importance of PAM

While IGA helps when it comes to managing access across your organisation, Privileged Access Management (PAM) is also key for keeping your most sensitive accounts secure. Unprotected privileged accounts are one of the most common entry points for attackers, since these would give them the ability to bypass security control, make changes, and steal confidential data.

This is why PAM solutions, like those offered by CyberArk, are essential for businesses looking to enforce the principle of least privilege. These solutions allow businesses to implement multi-factor authentication, monitor the activity of privileged accounts, and detect any suspicious behaviour in real time.

When used together, IGA and PAM can give businesses robust identity security. While IGA ensures that access has been appropriately granted across your organisation, PAM protects the accounts at the highest risk, reducing the risk of abuse from internal and external threats.

IGA and Compliance

These days, businesses are under increased pressure to demonstrate that access to their data is not only being controlled, but that it is actively monitored. Regulations like GDPR and NIS2 require businesses to be able to prove they know who has access to their sensitive systems and data – and also justify that this access is appropriate. IGA helps businesses to be compliant by automating access reviews, providing audit trails, and detecting any violations before they can become liabilities. These are vital for sectors like finance and critical infrastructure, where there are severe penalties for non-compliance.

Best Practices for IGA

Implementing IGA requires careful planning, as well as a deep understanding of your organisation’s cyber defences. Before you begin, you should map all users, roles, and access points. Establish clear, role-based access control (RBAC) policies that align with your business’ needs, and automate the provisioning, deprovisioning of users’ privileges wherever possible, as this can reduce human error. It’s also important to integrate your IGA efforts with your PAM  strategy to protect the accounts that are most at risk. Regular reviews of your IGA are also important, so you can stay secure and compliant over time.
