Everything You Need to Know About Zero Trust Network Access –
As we all adjust to the pandemic’s impact, our modes of communicating with each other are highly dependent on our devices. While relying on our personal devices may be optimal for personal communications, using them for sending and receiving confidential information related to our work can jeopardize our company’s security. Since the pandemic began, many individuals have shifted to working remotely, and businesses have increased their reliance on cloud-based solutions.
While cloud-based solutions may be optimal options for working remotely, they may also give easy access to hackers, security threats, etc. Therefore, companies using a cloud-based solution may be more vulnerable to different threats and with this vulnerability rises a need for choosing a secure layer of protection. Out of the different solutions available, opting for the Zero Trust Network Access Model can be the most suitable option available.

What is a Zero Trust Network Access Strategy?
A Zero Trust network security model works on the motto ‘Never Trust, Always Verify’. At its core, the Zero Trust network design was built on the assumption that there will always be attackers originating from both inside and outside the network. Therefore, with a Zero Trust Network Access no device or individual will be automatically trusted, even if they move past the perimeter security.
A Zero Trust network model needs verification whenever a device or a user requests access to resources, irrespective of whether someone inside the company’s network makes the request. A Zero Trust network doesn’t rely on different security features like edge servers, firewalls, VPNs for protecting restricted resources.
The Working of Zero Trust Network Access –
Zero Trust network access products and services build an environment that defends your physical and logical resources. The applications hosted on the network are hidden, and to access them, users will have to follow a few important steps:
- Verification when they sign on to the system.
- Validate the devices before entering the network. Users must ensure that the devices used are known, trustworthy, and updated on the security and the patches.
- Limit access depending on the POLP (principle of least-privilege) model. The user or device will be provided access to the resources they need depending on their role and designation in the company.
The Zero Trust network access solution includes various technologies to verify the user or the device and then offers access. Here are some of the technologies used in the ZTNA architecture:
- Multi-Factor Authentication (MFA)
- 2-Factor Authentication
- Network Access Control (NAC)
- Device Access Control
- Privileged Access Management (PAM)
Benefits of Incorporating ZTNA Model –
Listed below are some benefits you can get by using the ZTNA model:
1. Optimal for a remote working business model –
Unlike other security models, the Zero Trust security model offers secure and safe remote access to every user on the network. Zero Trust models also allow companies to build the network system a bit dynamic without impacting the security. Companies can also adjust the privileges and important systems to improve the infrastructure’s scalability. The model also offers a decent amount of control over the cloud-computing system, which is essential for remote working.
2. High security –
A Zero Trust model offers a high level of security to the company. This is done by dividing the company’s network system. No user will be allowed access to resources without proper authentication. Companies like InstaSafe offer ZTNA security with different features, ‘behavioral authentication’, which can identify user impersonation by analyzing past behaviors. The inclusion of such features in the InstaSafe ZTNA model can be quite beneficial for a company’s security.
3. Easy integration –
ZTNA models are quite easy to integrate. It also comes with an easy base. Therefore, it can complement anything and offer a transparent and seamless authentication process.
Zero Trust network models are one of the most preferred options for network security these days. Several companies in the country rely on the ZTNA model for protecting their organization from security threats, hackers, etc. With the ZTNA model, no user is trusted, and everyone will need the proper authentication for accessing the resources.
