Despite years of industry efforts to combat insider threats, malicious behavior can still sometimes be difficult to identify. As organizations work towards building a corporate cyber security culture, many have begun looking into to cover as many attack surfaces as possible.
This action is a step in the right direction, but it also has the potential to raise fears and generate negative responses from employees. Zero-trust security could instill demotivation and resentment if taken as a sign of poor faith and mistrust, accelerating turnover rates and bringing the Great Resignation to a peak.
How can an organization effectively navigate zero-trust without creating friction among employers and employees? In addition, how can they get there without holding trust-building exercises as part of an in-office environment?
Why trust matters in modern business environments
The security perimeter is no longer a physical location in a modern enterprise; it is a set of access points dispersed in and delivered from the cloud. In addition to identity, the authorization model should factor in the sensitivity of the data, the source location of the request, reliability of the endpoint, etc. The use of multiple cloud platforms and a growing number of endpoints can massively expand the attack surface.
The foundation of zero-trust security starts by eliminating the word trust. Criminals today don’t break into network perimeters; they log in with stolen credentials and then move laterally across the network, hunting for more valuable data. Protecting the path from identity to data is crucial – this is at the heart of an ID-centric zero-trust architecture. To do so, security teams should:
- Validate the user
- Verify the device
- Limit access and privilege
The layers that connect identity to data play essential roles in sharing context and supporting policy enforcement. A zero-trust architecture is continuously aware of identity and monitors for a change in context.
by the United States Government Office of Management and Budget (OBM) outlines why zero-trust architecture is crucial to securing web applications that are relied on daily. The SolarWinds attack reminds us that supply chain security is vital, and the recent incident also highlights how crucial effective incident response is, so finding a way to an improved security posture is imperative.
However, zero-trust does not mean encouraging mistrust through the organization’s networks, and companies should not have to rely on technologies alone for protection. When it is a team effort, security is best applied, and successful zero-trust depends on a culture of transparency, consistency, and communication across the whole organization. But how can organizations achieve this?
The two pillars of building (Zero) Trust
When building zero-trust in any organization, two key pillars must be considered – culture and tools.
As companies begin implementing zero-trust, they must also integrate it into their culture. Inform employees what’s going on, what the process of zero-trust entails, how it impacts and benefits them and the company, and how they can support the zero-trust process. By and challenging them to embrace skepticism towards potential threats, businesses are planting the seeds of security across their organizational ecosystem. Once employees understand the value of zero-trust, they also feel trusted and empowered to be part of the broader cybersecurity strategy.
Once zero-trust has been implemented at the core of an organization’s cybersecurity culture, the next step is to apply best practices to implement zero-trust. There are several measures that organizations can take, including:
- Use strong authentication to control access.
- Elevate authentication.
- Incorporate .
- (Micro)segment corporate network.
- Secure all devices.
- Segment your applications.
- Define roles and access controls.
Although Zero-Trust is technology agnostic, it is deeply rooted in verifying identities. One of the first steps is identifying the network’s most critical and valuable data, applications, assets, and services. This step will help prioritize where to start and enable zero-trust security policies to be created. If the most critical assets can be identified, organizations can focus their efforts on prioritizing and protecting those assets as part of their zero-trust journey.
The use of is crucial here. It is not a case of if to use it, but when. Phishing-resistant MFA can’t be compromised even by a sophisticated phishing attack, which means the MFA solution cannot have anything that can be used as a credential by someone who stole it. This includes one-time passwords, security questions, and imperceptible push notifications.
The challenge of implementing zero-trust
One essential problem that most enterprises are dealing with is the issue of fragmented IAM. As a result, zero-trust implementation is fraught with high complexity, risks, and costs.
The key reason behind this problem is that organizations are operating multiple identity security silos. In fact, the Thales 2021 Access Management Index report indicates that 33% of the surveyed organizations have deployed three or more IAM tools. Coordinating that many systems can, at a minimum, create operational complexity, but it can also increase the risk of fragmented security policies, siloed views of user activity, and siloed containment.
A zero-trust culture should help enterprises with IAM silos to move towards a standardized zero-trust security model, with standardized security policies and adjustments orchestrated from a central control panel across underlying silos. The process should provide insights on security policy gaps and inconsistencies and recommend security policy adjustments based on zero-trust security principles.
A zero-trust approach to security is to cover all attack surfaces and protect organizations, but they mean nothing without people using them appropriately. Aligning company success and security with employee success and security is crucial. Deploying a centralized IAM solution that covers all attack surfaces ensures optimal protection and helps build confidence in a zero-trust business and computing environment.
