Zero trust is a term that is being thrown around a lot in the security industry and has gained a great deal of traction in recent years. The framework is based on the idea that organizations should not automatically trust anything or anyone inside or outside of their networks. Instead, they should use a risk-based approach to determine which resources and users can be accessed and what level of access they should have.
Identity and access management (IAM) is a key component of the zero trust security framework. IAM systems allow organizations to manage user identities and permissions in a centralized way. This helps ensure that only authorized users have access to sensitive data and systems.
Micro-segmentation is another important component of zero trust security. Micro-segmentation allows organizations to create isolated segments of their networks, which can help reduce the risk of a breach. For example, if an attacker manages to gain access to one segment of the network, they will not be able to access sensitive data or systems in other segments.
Zero Trust has suffered a bit from hype lately, so make sure you scrutinize any security offerings before investing in them. It is important to align future security solution investments with threat intelligence to ensure the money is spent wisely and your organization is security posture is improved.
Here are seven tips for using the zero trust security framework:
1. Use Multi-Factor Authentication (MFA) and Identity and Access Management (IAM) systems to manage user identities, permissions and access.
2. Use micro-segmentation to create isolated segments of your network to keep bad actors from moving East and West once they have found a way into your environment.
3. Restrict access to sensitive data and systems only to authorized users.
4. Be sure to use security automation and orchestration tools in order to streamline your security processes and make use of current security investments where appropriate.
5. Make sure you have a good understanding of your environment and the risks involved.
6. Use threat intelligence and/or threat hunting to ensure you invest in the right security areas.
7. Perform regular audits to ensure that users have the appropriate level of access to resources.
8. Continually educate employees about the importance of cybersecurity and train employees on how to identify phishing attacks and other malicious emails
9. Regularly test your security controls to ensure they are effective in preventing attacks.
Zero trust can be a difficult concept for some organizations to wrap their heads around, but it’s important to remember that a zero trust security model is more secure than one that relies on predefined trust levels like a perimeter defense. By following the tips above, you can make sure your zero trust environment is strong and secure.
