The continuous and increasingly sophisticated cyber threats in this ever more complex digital era have made companies realize that it is no longer sufficient to rely on traditional security approaches.
The protection of company data and infrastructure can no longer rely on network perimeters, which are deemed inadequate to face modern security challenges.
Zero Trust Security emerged by bringing a new security approach that focuses on protecting external and internal threats.
As the name implies, Zero Trust Security eliminate “trust” in the network to ensure that each access must be verified first.
This article will take us to a deeper understanding of Zero Trust Security, the principles that underlie it, and how it is implemented in a company or organization. Check it out!

What is Zero Trust Security?
Zero trust Security represents a security model based on distrust of users, devices, or networks automatically.
Thus, each access requires permission to enter the system through a rigorous verification process.
The traditional approach considers internal network threats to be nil, safe, or even unlikely to have problems compared to external ones.
Unfortunately, today's more sophisticated cyber attacks are able to exploit even weaknesses in traditional security architectures.
According to Microsoft, Zero Trust Security implement strict verification based on user identities, devices, and more before gaining access to resources.
The risk of data leakage and identity-based attacks can be prevented, both from external and internal threats.

Principles of Zero Trust Security
The implementation of Zero Trust Security requires understanding several basic principles before applying it, namely:
1. Never Trust, Always Verify
Nothing is automatically considered safe. All access requests must go through strict authentication and authorization.
2. Least Privilege Access (Access with Minimum rights)
Access granted to users and the system only according to their needs. Intended to reduce abuse of access rights.
3. Micro-Segmentation
The potential spread of cyberattacks is limited by dividing the network into small segments when a security breach occurs.
4. Multi-Factor Authentication (MFA)
An authentication method for verifying a user's identity that is used more than once, before access to critical resources is granted.
5. Assume Breach (Always assume there is a violation)
Assuming the system has been or could have been hacked, so as to detect and respond quickly to threats, mitigation measures are needed continuously.
6. Continuous Monitoring and Analytics
The use of AI is implemented in monitoring and analytics systems to detect suspicious activity and conduct responses in real-time.

How To Apply Zero Trust Security?
The implementation of Zero Trust Security cannot be done in a single step. Its effectiveness requires a phased strategy in adopting this security model.
Here are the main steps that need to be done organization or company in implementing Zero Trust Security:
1. Identification of assets and sensitive Data
The company first identifies the digital assets that need to be protected, including sensitive data, applications, and critical systems.
Thus, the company can precisely determine the security measures of each asset.
2. Application Multi-Factor Authentication (MFA)
The implementation of MFA becomes a necessity as the authentication level is higher for each asset.
Thus, only authorized users can access the system even if their credentials are hacked.
3. Principle Use Least Privilege Access
The risk of data misuse and insider threats attacks can be reduced by restricting access rights.
Each user and device is only given the minimum as needed to carry out their duties.
4. Apply Micro-Segmentation
The implementation of micro-segmentation strategy is very helpful in preventing security breaches from spreading throughout the network.
Only the segments affected by the problem are affected through network sharing and access control. This makes it easier for companies to deal with problems when a system hack occurs.
5. Monitoring and detection of threats Real Time
AI dan machine learning adopted in security monitoring systems to detect suspicious activity patterns.
The information received will be faster and more accurate because it is able to send reports or threat responses in real-time before major problems occur.
6. Use Of Technology Zero Trust Network Access (ZTNA)
Previously, the majority of companies used traditional VPN, which are now starting to switch to ZTNA.
ZTNA is considered more secure because access to applications and data is only granted based on the user's identity, the device used, and company policies.
7. Employee education and training
All employees in the company are responsible for cybersecurity, not just the IT team.
Therefore, comprehensive education and training on Zero Trust Security regularly conducted to all users to understand the importance of maintaining data security.
Benefit of Zero Trust Security For Companies
Implementation of Zero Trust Security the company's security system has many benefits, including:
- The automatic/default “no trust” approach, makes the risk of data leakage minimized which improves data security
- Multi-layered authentication and tight security allow for less exploitation by hackers during cyberattacks
- Micro-segmentation and strict access controls can limit attacks in networks that move in all directions
- Data security regulations such as General Data Protection Regulation (GDPR) and ISO 27001 must be complied with by the company, because in accordance with Zero Trust Security
- Zero Trust Security is flexible, meaning that employees can access company resources anywhere and anytime

Challenges in adapting the Model Zero Trust Security
Although it offers a myriad of benefits and advantages, there are some challenges that companies must face in its application:
- For companies with outdated IT infrastructure, it becomes a significant challenge because Zero Trust Security requires fundamental changes in security architecture.
- Investment in cost and time by the company. Investment in software, hardware, and workforce training costs more and time is not short
- Changes made by the company can cause rejection by some parties, especially if the policy is considered too complicated and hinders employee performance
- Companies need to find IT engineers who have a deep understanding of Zero Trust Security Architecture to ensure it can run effectively
The Role of Zero Trust in Regulatory Compliance
Current regulatory developments require companies to implement strict security standards due to increased attention to cybersecurity.
Regulatory requirements such as, GDPR, Health Insurance Portability and Accountability Act (HIPAA), and National Institute of Standards and Technology (NIST) demands stronger protection, tighter access control, and security monitoring operated.
Conclusion
Security Model Zero Trust Security bringing new changes to the traditional network security world towards a more modern and complex one.
Based on principle. “Never Trust, Always Verify” which is able to provide much better data protection against cyber threats.
Of course, in its implementation, it cannot be done instantly. Zero Trust Security needs to be implemented gradually by applying layered authentication, network segmentation, and real-time.
By adopting Zero Trust Security in an enterprise security system, it can increase resilience, layer data protection, and comply with evolving security regulations.
