What is Zero Trust?
Zero Trust is a security framework which implicitly trusts any device, user, network or service, and requires constant confirmation of authentication and authorization that is used for accessing corporate information. It is a Zero Trust model assumes that the possibility of a breach is certain and could have already occurred, so it imposes restrictions on access and provides alerts for suspicious activities. Zero Trust is a framework to protect corporate data in the digital age of today. It is specifically designed to address the challenges that technology brings to today’s enterprise, such as security threats from insiders as well as secure remote access ransomware-related threats, and so on.
Zero Trust security has three principal concepts:
1. Continuous monitoring
According to the Zero Trust model, we believe that there are attackers within and outside our organization boundary, so no one can be trusted automatically. Zero trust database access verifies every single user’s attempt.
2. Most privilege
Although users frequently access information from the company in their daily role the principle of least privilege makes sure that employees are given only the amount of access they require to fulfill their duties efficiently. Based on “a need to be aware” basis. This reduces the users’ exposure to sensitive information. In the event of a security breach, Zero Trust limits the impact of the incident and allows security teams to react and mitigate the threat.
Continuous monitoring and lowest privilege access are not possible without total automation of these procedures. Zero Trust embraces the full use of automated security procedures to obtain the lowest privilege access and to constantly monitor and verify each and every data entry made by each user from within and outside the company.
What is the reason ZTNA not sufficient to be used for SaaS Data Security?
The most popular application of this Zero Trust security model is the protection of remote access, also known as Zero Trust Network Access (ZTNA). This product class eliminates the requirement for a VPN that is not a standard feature and makes use of its Zero Trust principles to verify the remotely accessible network via micro-segmentation of the device and network, as well as access control.
ZTNA solutions provide remarkable and complete micro-segmentation, as well as access control by analyzing identity as well as network and device metadata, like the IP address of an individual, OS versions, and the roles of users. ZTNA is able to solve multiple major threats, including attack on accounts (examples of access permitted to unknown devices and networks). When ZTNA solutions allow access, the user is able to connect to approved applications with no micro-segmentation of the “kind” of information in the applications is able to be accessed, altered and shared. Particularly in the case of SaaS applications, the user can fully access and alter SaaS data, without having to worry about any further restrictions on access to data and control provided through ZTNA. ZTNA solution.
In the case of an employee, for instance, one who leaves a company can steal and scrape substantial amount of sensitive data from the company before leaving the company just because the identity of their device and network metadata are recognized by ZTNA. ZTNA solution. There isn’t any context surrounding the data extraction process or what kind of data is being accessed. So, businesses that are implementing ZTNA solutions are still vulnerable to a variety of day-to-day threats:
Employees who resign for leaking company information
Inadvertent sharing of company data with personal accounts
Internal overexposure and consumption sensitive information
Third party collaborators exposed to data of the company for ever
Data can be shared with anyone who has a link
How can you be sure that there is zero Trust Data Access?
Zero Trust Data Access (ZTDA) is based on the concept of least privilege along with micro segmentation and applies it to Software as a Service (SaaS) applications, which are among the most important sources of data for any enterprise seeking to conform to ZTDA. Zero Trust model.
ZTDA is a new guideline principle that gives the granularity needed to establish that trust implicitly isn’t granted to any individual inside or outside the company over and above the layer of identity, and/or deeply embedded in the SaaS application layer. This allows more specific security rules to be applied to the end users and organizations that are both external and internal in every SaaS applications.
ZTDA secures the essential resources that push the modern day business forward.
When ZTNA micro segments are focused on networks, identities, and gadgets, ZTDA micro segments on users, third parties, third groups, HR employee status and file type, place of origin, PII detection, malware detection, and much more.
ZTDA implements all three Zero Trust principles as follows:
1. Continuous monitoring
ZTDA platforms are connected to all external and internal user activities, SaaS assets metadata, and data enrichments originating from many interconnected integrations like IDP, EDR, and HR platforms. All these data points are used to allow deep micro-segmentation at different levels, including users groups, assets as well as domains, employment status, and many more. ZTDA platforms maintain a live list of your SaaS ecosystem’s metadata, without the requirement to replicate and keep SaaS host data.
2. The least privilege
Based on the unification of catalog and the data enhancements ZTDA platforms are constantly revoking access to data for users both external and internal to ensure the lowest privilege model in a large scale. Users are able to be granted access or share the same data repeatedly to ensure that business-enabling continues in the same way. In time, businesses that implement ZTDA platforms dramatically reduce their vulnerability, the quantity of individuals with access to sensitive data and the extent of any possible breach.
ZTDA platforms provide automated workflows that are based on a comprehensive micro-segmentation of users and collaborators, assets groups, and so on. The workflows that are automated are not necessarily based on opinion or hardcoding, but are rather adaptable and customizable, allowing them to trigger in response to any user or any other anomalous event that is identified. ZTDA platforms have a vast range of remediation options, which can be triggered on demand as well as fully automatized.
How can you implement Zero Trust on the data layer?
The security team or program is not identical. Therefore below are the main steps to implement the Zero Trust Access to Data Access model:
Visualize – Understand all collaborators, users and groups, assets, and risk.
Reduce – address identified risks to increase your security measures.
Automate workflows to avoid situations that pose a high risk.
Adjust your security requirements based on changes in your business.
