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.<\/p>\n\n\n\n

The protection of company data and infrastructure can no longer rely on network perimeters, which are deemed inadequate to face modern security challenges.<\/p>\n\n\n\n

Zero Trust Security<\/em><\/strong> emerged by bringing a new security approach that focuses on protecting external and internal threats.<\/p>\n\n\n\n

As the name implies, Zero Trust Security<\/em> eliminate \u201ctrust\u201d in the network to ensure that each access must be verified first.<\/p>\n\n\n\n

This article will take us to a deeper understanding of Zero Trust Security<\/em>, the principles that underlie it, and how it is implemented in a company or organization. Check it out!<\/p>\n\n\n\n

What is Zero Trust Security<\/em>?<\/h2>\n\n\n\n

Zero trust Security<\/em> represents a security model based on distrust of users, devices, or networks automatically.<\/p>\n\n\n\n

Thus, each access requires permission to enter the system through a rigorous verification process.<\/p>\n\n\n\n

The traditional approach considers internal network threats to be nil, safe, or even unlikely to have problems compared to external ones.<\/p>\n\n\n\n

Unfortunately, today's more sophisticated cyber attacks are able to exploit even weaknesses in traditional security architectures.<\/p>\n\n\n\n

According to Microsoft<\/a>, Zero Trust Security<\/em> implement strict verification based on user identities, devices, and more before gaining access to resources.<\/p>\n\n\n\n

The risk of data leakage and identity-based attacks can be prevented, both from external and internal threats.<\/p>\n\n\n\n

The implementation of Zero Trust Security<\/em> requires understanding several basic principles before applying it, namely:<\/p>\n\n\n\n

1. Never Trust, Always Verify<\/em><\/h3>\n\n\n\n

Nothing is automatically considered safe. All access requests must go through strict authentication and authorization.<\/p>\n\n\n\n

2. Least Privilege Access<\/em> (Access with Minimum rights)<\/h3>\n\n\n\n

Access granted to users and the system only according to their needs. Intended to reduce abuse of access rights.<\/p>\n\n\n\n

3. Micro-Segmentation<\/em><\/h3>\n\n\n\n

The potential spread of cyberattacks is limited by dividing the network into small segments when a security breach occurs.<\/p>\n\n\n\n

4. Multi-Factor Authentication<\/em> (MFA)<\/h3>\n\n\n\n

An authentication method for verifying a user's identity that is used more than once, before access to critical resources is granted.<\/p>\n\n\n\n

5. Assume Breach<\/em> (Always assume there is a violation)<\/h3>\n\n\n\n

Assuming the system has been or could have been hacked, so as to detect and respond quickly to threats, mitigation measures are needed continuously.<\/p>\n\n\n\n

6. Continuous Monitoring and Analytics<\/em><\/h3>\n\n\n\n

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<\/em>?<\/h2>\n\n\n\n
\"Data
Data security program code (source: Freepik)<\/figcaption><\/figure>\n\n\n\n

The implementation of Zero Trust Security<\/em> cannot be done in a single step. Its effectiveness requires a phased strategy in adopting this security model.<\/p>\n\n\n\n

Here are the main steps that need to be done organization or company in implementing Zero Trust Security<\/em>:<\/p>\n\n\n\n

1. Identification of assets and sensitive Data<\/h3>\n\n\n\n

The company first identifies the digital assets that need to be protected, including sensitive data, applications, and critical systems.<\/p>\n\n\n\n

Thus, the company can precisely determine the security measures of each asset.<\/p>\n\n\n\n

2. Application Multi-Factor Authentication<\/em> (MFA)<\/h3>\n\n\n\n

The implementation of MFA becomes a necessity as the authentication level is higher for each asset.<\/p>\n\n\n\n

Thus, only authorized users can access the system even if their credentials are hacked.<\/p>\n\n\n\n

3. Principle Use Least Privilege Access<\/em><\/h3>\n\n\n\n

The risk of data misuse and insider threats attacks can be reduced by restricting access rights.<\/p>\n\n\n\n

Each user and device is only given the minimum as needed to carry out their duties.<\/p>\n\n\n\n

4. Apply Micro-Segmentation<\/em><\/h3>\n\n\n\n

The implementation of micro-segmentation strategy is very helpful in preventing security breaches from spreading throughout the network.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

5. Monitoring and detection of threats Real Time<\/em><\/h3>\n\n\n\n

AI dan machine learning<\/em> adopted in security monitoring systems to detect suspicious activity patterns.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

6. Use Of Technology Zero Trust Network Access<\/em> (ZTNA)<\/h3>\n\n\n\n

Previously, the majority of companies used traditional VPN<\/a>, which are now starting to switch to ZTNA.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

7. Employee education and training<\/h3>\n\n\n\n

All employees in the company are responsible for cybersecurity, not just the IT team.<\/p>\n\n\n\n

Therefore, comprehensive education and training on Zero Trust Security<\/em> regularly conducted to all users to understand the importance of maintaining data security.<\/p>\n\n\n\n

Benefit of Zero Trust Security<\/em> For Companies<\/h2>\n\n\n\n

Implementation of Zero Trust Security<\/em> the company's security system has many benefits, including:<\/p>\n\n\n\n
