What ''Zero Trust'' Actually Mean?
The term "Zero Trust Security" has been tossed around a lot lately, but what does it actually mean? In a nutshell, Zero Trust Security (also known as the Zero Trust Model) is a security approach that requires all users, regardless of their location or device, to authenticate and authorize before accessing any data or applications.
In other words, under a Zero Trust security model, no "trust" is given to anyone by default – all users, devices, and networks must be verified and authenticated before any data can be accessed.
This article will explain everything you need to know about Zero Trust security, including its benefits and how it can be implemented within your organization.
How Does Zero Trust Affect Cybersecurity?
1. User access control
Zero Trust security is a security model that requires organizations to verify every user and device before allowing them access to data or applications. The term "Zero Trust" comes from the fact that organizations should not blindly trust any user, even if they are inside the network perimeter.
A good implementation of the Zero Trust model means that your organization has good user access control.
2. Detection of insider threats
Since the Zero Trust model treats all users with distrust, it's a great tool for helping to detect insider threats. A Zero Trust model should include user activity monitoring, which involves tracking the actions of users within the organization and looking for anomalies that could indicate malicious behaviour. This can be done using user activity logs, security cameras, and other tools.
3. Continuous authentication
Continuous authentication is an essential component of Zero Trust security architectures. Organizations can ensure that only authorized users have access to sensitive data and systems by continuously verifying the identity of users, devices, and apps. Continuous authentication can be implemented in several ways, including user behaviour analytics, multi-factor authentication, and biometrics.
4. Erases perimeter security
Zero Trust security is a security model that provides assurance by validating user identities and devices before granting access to data or applications. On the other hand, Perimeter security relies on building walls around a network to keep unauthorized users out. In a Zero Trust model, perimeter security is done away with, and all areas of the network must be treated with distrust.
5. Increased protection for company assets
In a Zero Trust model, company assets receive better protection than a traditional perimeter security model. All assets are placed behind strict access controls, limiting the possibility of unauthorized access and preserving confidentiality.
6. Better containment during security incidents
When an organization experiences a security incident, the first step is to contain the damage. Network segmentation isolates the affected systems from the rest of the network. This ensures that the incident can be contained and stopped from spreading further.
In a Zero Trust framework, your network is already well-segmented into different security zones to ensure that incidents are contained. This means better containment and faster response times during security incidents.
Tips for Implementing Zero Trust Security
1. Segment your company network
When it comes to segmenting your company network, there are a few different approaches you can take. The most important thing is to figure out your goals for segmenting the network and choose the best method.
One common goal is to improve security by isolating sensitive data from the rest of the network. This can be accomplished by creating separate segments for different types of data or by creating segments for different user groups.
Another common goal is to improve performance by segmenting the network into different traffic types. For example, you might create a separate segment for video or data traffic.
Finally, you might also choose to segment your network for other reasons, such as to comply with regulatory requirements or to improve manageability.
2. Use VPN
A virtual private network, or VPN, can be a helpful tool when you're looking to protect your online privacy and security. A VPN encrypts the data you send and receive over the internet and routes it through a secure server, making it difficult for anyone to intercept or access your information.
There are a few things to remember when choosing a VPN, such as the security protocols it uses, the level of encryption it offers, and whether or not it keeps logs of your data. You'll also want to ensure the VPN is compatible with your devices and operating systems. Once you've found a VPN you're happy with, setting it up is usually a simple process.
3. Implement the principle of least privilege
The principle of least privilege is a security concept that requires users to have the bare minimum permissions necessary to do their jobs. This means users should only have access to the resources and information needed to perform their job duties. Any other permissions beyond that should be removed.
The principle of least privilege is a key security measure that can help to prevent unauthorized access and data breaches. By restricting user permissions, you can minimize the potential damage that can be done if a user's account is compromised. Implementing the principle of least privilege can be challenging, but protecting your data and your company is worth the effort.
4. Require authentication before accessing any company resources
The Zero Trust model is based on the principle that no user can be trusted implicitly just because they are on-premises. This model requires all users to authenticate themselves before accessing any resources. This ensures that only authorized users can access corporate data and helps to prevent data breaches.
Zero Trust Security is a term for security models that don't rely on predefined trust levels. In a Zero Trust security model, all users, devices, and networks are untrusted until proven otherwise. This approach is becoming more popular as traditional security models are being bypassed more frequently. Zero Trust security is not a silver bullet but a step in the right direction for improving cybersecurity.
