Traditional security measures are starting to become weak against the more sophisticated nature of emerging cyber threats, and businesses need more advanced solutions to prepare their networks. This is where Zero Trust comes into play. It is a groundbreaking security framework that revolutionizes the way companies approach security.
By eliminating the implied trust in the systems and the end-users within a network, a Zero Trust approach asks for constant verification and therefore minimize insider threats while also protecting it via strict access controls. This article will explain what is a Zero Trust approach, how it is used, and how it acts as a pillar of regulatory requirements and compliance.
Compliance and Regulatory Requirements
Compliance is a significant issue for web-based organizations due to the massive amounts of sensitive data they store in their networks. Since most of this information belongs to their clients or business partners, authorities set up various regulations to standardize the way sensitive data is protected.
These regulatory requirements cover everything from the required technological solutions to the legal foundation of sensitive data protection. It also encompasses how organizations should act when there is a security bridge and how should they announce it to their customers.
These regulations are always tailored to specific industries and regions; for example, General Data Protection Regulation (GDPR), is the main authority in Europe in terms of a guideline to protect personal information. On the other hand, Health Insurance Portability and Accountability Act (HIPAA) is a US act that sets the standards for protecting personal health information in healthcare organizations. There are many regulations such as these, but I guess you understood the point.
Meeting compliance requirements is a challenging task. The threats always tend to evolve, you need highly complex and technological environments, and the threat landscape is simply too big. To comply with these standards, organizations need to invest significantly in security solutions, have appropriate policies in place, and conduct security audits while also planning for an incident.
Although it is challenging, compliance is a must for most organizations as failure to comply with regulatory requirements ends up in hefty penalties, legal issues, and lost trust in your business.
The Evolution of Zero Trust
The main goal of traditional security frameworks has always been to protect the network from outside threats. These solutions assume a perimeter, meaning that everything within that perimeter (those within the network) is internally secure. However, this assumed perimeter defense proved to fail against the complex nature of cyber threats that include both insider and outsider risks.
The concept of Zero Trust mainly emerged as a response to this “perimeter defense”. It contradicts the traditional methods by assuming that not a single user or component within a network is secure. Even if someone is an everyday user of the network, Zero Trust asks for constant verification and enforces strong access controls.
The increasing popularity of cloud computing, remote work models, and the sophistication of cyber threats resulted in the evolution of such a security framework. As the traditional network perimeter started to disappear, organizations needed a way to bring security to the doorsteps of the users.
By using Zero Trust, these organizations can now minimize lateral movement within a network and mitigate insider risks. Zero Trust security principles outline the significance of access restrictions within a network, granular control and monitoring, and tracking user behavior closely.
Benefits of Zero Trust in Meeting Compliance Requirements
Implementing Zero Trust security in a cloud environment offers various benefits for organizations in their race to achieve compliance. By adopting a Zero Trust approach, they can meet the technical requirements of security standards while also strictly restricting access to sensitive information.
Enhanced Data Protection and Privacy
One of the most significant benefits of Zero Trust is its data-centric approach to protecting sensitive information whereas traditional methods have a location-based understanding. By using strong security services such as access controls, advanced encryption, and data classification, Zero Trust is a great way to improve overall privacy in a network.
Granular Access Controls and Least Privilege
Thanks to its least-privilege approach to granting access, Zero Trust helps companies enforce strong restrictions on access. The main idea here is to provide access only to resources they need to do their tasks and nothing more. This helps minimize the risk of unauthorized access, ensure a need-to-know basis, and mitigate compliance issues that may arise from unnecessary access to sensitive data.
Continuous Monitoring and Auditing Capabilities
Monitoring user behavior, tracking user activities, and checking the network traffic are all important points of a Zero Trust approach. These practices enable organizations to have more control and visibility over their networks. They also allow quick detection and response processes for potential incidents, identify breaches, and generate logs for compliance audits.
Incident Response and Remediation in a Zero Trust Environment
Due to granular security controls and restricted access, a Zero Trust environment can help organizations quickly contain and quarantine a data breach. This means minimized attack surface and better remediation. By segmenting the network into smaller chunks to implement granular control, the impact of a data breach and lateral movement can be drastically limited.
Alignment with Compliance Frameworks
Aside from the highly capable security services and technologies included in a Zero Trust environment, it is also very much appreciated and promoted in most of these security regulations. Zero Trust aligns with the core principles of these standards, so it is a great foundation for meeting compliance requirements.
Compliance with security regulations is not only something that will benefit your organization, but now it is also necessary to prevent legal penalties. Although it is a challenging process, there is a great security framework to build a foundation to work on; a Zero Trust approach. By following the core practices in this framework, organizations can simplify their compliance journey.
