When it comes to new approaches to security, the uniquely positioned framework "zero trust security" is well-equipped to address the new security challenges enterprises face.
According to Forbes’ risk-based security report, 3,813 breaches were reported during the first six months of 2019, exposing over 4.1 billion records. That’s a huge number! And a reason why now is more important than ever to consider the new security framework that’s been doing the rounds for quite some time now.
Zero trust refers to a security framework that requires users to authenticate, validate, and authorize themselves for security configuration to get access to data and applications. The security framework does not differentiate between users within or outside an organization. The primary assumption of zero trust is that there is zero traditional network edge. It runs on the idea that networks can be within the cloud or become a hybrid with other resources in any location.
The aim is to secure data and infrastructure for modern digital transformation. Zero trust security addresses the new challenges in businesses like ransomware threats, the security of remote workers, and hybrid cloud environments. It is considered the best strategy to build a cybersecurity ecosystem.
Zero trust security works on the following principles.
Terminate each connection
Technologies like firewalls inspect the delivered files called the passthrough approach. So, the alerts are often late if they detect a malicious file. However, zero-trust security terminates all connections for inspecting the traffic, especially the encrypted files and websites. The inspection happens in real-time to stop ransomware, malware, etc.
Zero trust security verifies the rights and access requests based on context. It also checks the user identities, location, device, type of content, and application based on these policies. It continuously reassesses the user’s access privileges because of the adaptive policy system.
Eliminate the attack surface
Users can directly connect to the applications and resources with zero trust security’s help. Direct user-to-app connections reduce the risk of lateral movement and prevent any compromised device from infecting nearby resources. Moreover, zero trust benefits users by making user applications invisible on the internet to avoid getting discovered or attacked.
Enterprises have already started to embrace zero trust security over traditional security since it offers improved security while simultaneously improving flexibility and reducing complexity. Here’s how zero trust outperforms the traditional model:
Zero trust security enables users to connect with in-house applications securely. They can get these applications without exposing them to the internet or gaining network access.
On the other hand, traditional security uses the castle and moat concept (everyone inside the network is trusted by default). The user finds it difficult to access the applications from outside and is bound to trust everyone in the network. The problem here is that if a hacker poses as an insider, they get access to everything available within the network.
Zero trust security accepts no trust units before it awards the user admittance to anything. It also checks other forms of data before giving access to the client. In short, this security model pays heed to who the user is. So, it confirms the user’s identity every time the latter asks for security access.
Traditional security works on an entirely different principle as compared to zero trust. It gives value to where the user is coming from in the network. It utilizes the trust system because the client’s IP address or area characterizes the user identity in the system.
Modern techniques and technologies
Zero trust security tends to the concerns of cloud-facilitated data to re-examine a secure network plan. It solves these issues by accepting that everything is reliable. It grants trust only after the verification and authorization process.
However, traditional security lacks the modern techniques and technologies to monitor a network plan. The lack of these tools and services may compromise the system of the cloud-facilitated data, applications, and users.
Here is how zero trust benefits over traditional security:
Zero trust security depends on the possibility that a business must have a default trust option for any element that crosses its border. It verifies anything that attempts to associate with or access the framework. A zero-trust network is different from regular VPNs and firewalls, as it secures access to all applications within an enterprise. Additionally, zero trust replaces traditional security technologies by offering better authentication methods.
So when it comes to taking digital transformation initiatives, proactive protection is required in this new decade. Therefore, a wise move for enterprises will be to implement zero-trust security.
