Determining the right network access control (NAC) security policy for your organization isn’t an easy task.

It’s often a balancing act between keeping your network secure and ensuring employees can access the systems they need to do their jobs.

Role-based access control (or RBAC) can be a good way of ensuring your network is protected. If you’ve been considering implementing RBAC in your organization but aren’t entirely sure of the benefits, this article will answer your questions.

What is role-based access control?

Role-based access control is a way of restricting access based on a user’s role within an organization. This means that users aren’t assigned permissions directly but are instead given roles that govern their levels of access. Depending on their job and responsibilities, a user may have one or more roles.

Let’s say, for example, you have a staff database on your network, which contains all your employees’ contact details and contractual information.

Everyone in the organization may have access to edit their own personal details. Managers may have access to edit their team’s information, but no one else’s. Your HR team may have full access to the database to view and edit everyone’s data.

RBAC works on the Principle of Least Privilege (PoLP). This means users have the minimal level of access needed to carry out their job.

RBAC isn’t the only access control method available. There are other options you can consider, like attribute-based access control (ABAC), policy-based access control (PBAC) and access control lists (ACL). However, role-based access control is one of the most effective ways of not only keeping networks secure but improving organizational efficiency.

A study by NIST has shown that role-based access control addresses most of the needs of government and commercial organizations.

Why is role-based access control so important when it comes to network security?

Networks are more susceptible to security breaches than ever before. People working from home and the introduction of BYOD policies mean more endpoints that can be compromised.

In fact, according to IBM, it’s estimated that data breaches in 2021 cost businesses an average of $4.24 million.

With this in mind, it’s essential to ensure networks stay safe. Here’s how role-based access control can provide security for businesses large and small.

I. It makes it easy to ensure networks are secure

Setting up permissions for networks is relatively straightforward. However, as people start, leave, and move around organizations, permissions can become less efficient. Users may end up with access to systems they no longer need.

RBAC means IT departments can effectively manage what access people have with a click of a button.

Let’s go back to the example of the staff database above and say that a new staff member has joined the HR team. Rather than setting access at a user level, you can add them into the ‘HR’ role so they can have full access to the system.

A few years later, let’s say the staff member moves into the sales team, meaning they no longer need full access to the staff database. Rather than changing every single point of access they have, it’s just a case of adding them into the ‘sales’ role instead.

II. It reduces the attack surface

It’s estimated that one in four data breaches result from human error. With RBAC, if a member of staff causes an accidental (or intentional) data breach, there will be less impact.

Let’s say someone is a victim of a phishing attempt, and a hacker obtains their login details. The hacker will only be able to access the information that the member of staff has through the roles they have been allocated.

This means even if a data breach occurs, most of your information will still be safe.

III. It eliminates the risk of ‘insider threats’

Disgruntled employees can often try and settle the score by leaking confidential data or deleting important information. Earlier this year, an IT technician in the UK was jailed for 21 months for wiping data from the school he was formerly employed at after being fired.

As role-based access control gives just enough access to ensure staff can carry out their jobs, it minimizes the risk of users causing intentional harm to your networks.

Similarly, if you work with any third parties, you can use RBAC to assign them pre-defined roles and limit what they can view or edit. Once you stop working with them, you can quickly remove their permissions.

IV. It can quickly scale and adapt

As RBAC deals with overarching roles rather than individual permissions, it can grow as an organization’s IT requirements do.

Let’s say you acquire a new application for your organization. Role-based access control makes it easy to create new permissions as well as set different levels of permissions quickly. As a result, you can ensure any new hardware or software stays secure and that the right people have access.

V. It can ensure you stay compliant

Some industries, like healthcare and financial services, are heavily regulated and have stringent compliance regulations in place. For example, the Health Insurance Portability and Accountability Act (HIPAA) states that only certain people should be allowed access to specific systems.

Role-based access controls can ensure that organizations in these industries do what is required of them, minimizing the risk of security breaches as well as fines for willful violations of the law.

How Portnox can help with your RBAC requirements

Role-based access control can be an extremely efficient way of ensuring network security and can be as top-level or granular as your organization demands. The key is developing a solid strategy before creating and assigning roles.

Which parts of your network need access control, which departments need permissions, and how will you assign people to the right roles?

First coined by research firm Gartner in 2019, SASE has become a hot topic in the IT industry in just a few short years. Undoubtedly accelerated by the COVID-19 pandemic, SASE has captured the attention of IT professionals in the network and security landscape as they prepare for an increasingly cloud-centric way of working. 

However, with so much hype surrounding SASE, many people wonder whether it lives up to its promise to future-proof corporate networks. Or, in other words, is the hype actually overhype? And does SASE deliver the simplified but secure networking reality we’ve all been waiting for? Let’s get into it. 

What is SASE?

Secure access service edge (SASE) is a framework for network architecture that combines VPN and SD-WAN capabilities with cloud-native security functions to securely connect users, systems, and endpoints to applications and services anywhere. 

It converges network security solutions like secure web gateways (SWG), cloud access security brokers (CASB), firewall as a service (FWaaS), and zero-trust network access (ZTNA) with SD-WAN to create a unified, cloud-native service. But why has it garnered so much attention?

What Problems Does SASE Promise to Address?

In the past, companies would implement network access with siloed point solutions that were often complex, costly, and difficult to manage. This hurt IT agility and prevented enterprises from scaling their networks effectively and securely. And this issue has only become more challenging as companies shift from on-premise to the cloud. 

SASE offers a solution to these problems and more. It promises to simplify network security in the cloud, improve efficiency and security, and reduce costs. For example, with SASE, organizations can fine-tune network access control (NAC) and secure seamless access for users, achieve real-time application optimization, apply consistent security policies, enable more remote and mobile access, and more. 

In simple words, SASE promises a way to future-proof your business. If you suddenly experience a surge in traffic or decide it’s time to expand into other regions, you can rely on SASE to keep up. Because it’s a cloud-based distributed service, you can add or remove capabilities as needed and ready your network at breakneck speed, all without purchasing additional software and managing new contracts. 

Why SASE Is Failing To Live Up to the Hype

Despite the many promises SASE offers, many companies are struggling to realize these benefits for several reasons. Successfully adopting and implementing SASE presents many challenges for organizations. And at the same time, many security vendors don’t yet have the skills or experience with SASE to deliver on its promises. Or in other words, SASE can work brilliantly when done well, but more often than not, this isn’t happening. 

The Hurdles to SASE Realization

A Paradigm Shift

Some people argue that SASE is nothing new but rather a consolidation of various security tools already in existence. However, while this statement has some truth, SASE requires a paradigm shift in organizational mindset. SASE shifts security from a site-centric model to a more user-centric and contextual-based approach. This means security teams have to rethink how they view the network. 

Additionally, consolidating these tools under a unified solution means companies need to break down silos between networking and security teams. These teams need to collaborate, and as a result, roles may need to be more flexible. 

When organizations fail to embrace these changes, they don’t realize the true potential of SASE. 

A Confusing Vendor Ecosystem

Security vendors are all too aware of SASE’s hype and leverage this with non-stop marketing. Unfortunately, this can leave many companies confused about the tools and methodologies they need to help their business stay competitive. 

And even when an organization decides on a specific set of tools to adopt, it’s not as simple as choosing a vendor that offers these tools. The organization also needs to look closely at its existing tech stack for duplicative capabilities. Failing to do this can lead to tool sprawl – where unnecessary purchasing of new IT tools leads to redundancy, wasteful spending, and increased system complexity. 

And then there’s the risk of vendor lock-in. Adopting SASE is an excellent way for companies undergoing cloud transformation to simplify the security process and cover many compliance requirements. However, companies also have to accept that they’re getting all capabilities from one supplier and that this comes with a cost. If the chosen SASE product becomes outdated, switching to a new one might not be straightforward. 

A Young SASE Market

Legacy hardware vendors are increasingly offering SASE architecture to rise to the current demand. However, with their lack of expertise, these vendors might not be the best option. For example, they could lack the cloud-native mindset to bring the SASE architecture to life, resulting in cost and performance problems. Also, traditional vendors often lack the experience in evaluating context, a core principle of SASE, limiting their ability to make context-aware decisions. And lastly, some solutions might come up short because the providers only have experience in either networking or security, but not both. 

The Future of SASE

There’s no doubt that as the current IT landscape continues to mature, there will be an increased need for simplified network and security management. And we see this reflected in attitudes toward SASE. For example, Gartner predicts that by 2025, 60% of all enterprises will have clear strategies to adopt SASE. 

But how quickly SASE will become the new norm is still up for debate. Today, many companies are shifting a significant proportion of their environment to the cloud and outsourcing SD-WAN management. At the same time, they’re choosing to maintain control over their security services internally. As a result, these companies may not be in a rush to move to the SASE approach because their current setup works well enough. 

We could also see SASE adoption massively boosted if the major cloud suppliers decide to incorporate SASE services in their licensing models. Still, we’ll have to wait to see if this becomes a reality. 

As it stands today, the future of SASE looks promising, but it’s not set in stone. 

Wrapping Up

SASE is a powerful concept, but it’s still in its infancy. This means organizations and vendors are still ironing out the issues that come with new technologies. And where there’s new tech, there’s always resistance. However, resistance isn’t always a bad thing – modern cybersecurity encourages us to do away with implicit trust and be cautious and deliberate in our actions.
