Comptia Security+ SYO 701 Free Training | Zero Trust | Domain 1 E9

Zero Trust is a security model that operates on the principle that no entity, whether inside or outside the network, should be automatically trusted. Instead, every access request must be verified before granting permission. The core tenets of Zero Trust include:
Verify Explicitly: Always authenticate and authorize based on all available data points, including user identity, location, device health, service or workload, and data classification.
Use Least Privilege Access: Limit user access with just-in-time and just-enough-access (JIT/JEA), risk-based adaptive policies, and data protection to minimize lateral movement.
Assume Breach: Design systems with the assumption that an attacker could already be within the network. Segment access and use encryption and analytics to detect and respond to suspicious activities.
This model contrasts with traditional security models that rely on defined perimeters and trust entities within those perimeters. Zero Trust aims to address modern security challenges, such as cloud computing, remote work, and sophisticated cyber threats, by continuously verifying every attempt to access network resources.
The Zero Trust security model is built upon several key components that work together to ensure a secure and resilient network. These components include:
Identity and Access Management (IAM):
Multi-Factor Authentication (MFA): Ensures that users provide multiple forms of verification before accessing resources.
Single Sign-On (SSO): Simplifies and secures user access by allowing users to authenticate once and gain access to multiple resources.
Identity Governance: Manages user identities and enforces policies to ensure only authorized users have access.
Device Security:
Endpoint Detection and Response (EDR): Monitors and responds to threats on endpoints (e.g., laptops, smartphones).
Mobile Device Management (MDM): Controls and secures mobile devices accessing the network.
Device Health Attestation: Verifies that devices meet security standards before granting access.
Network Security:
Microsegmentation: Divides the network into smaller, isolated segments to limit the spread of threats.
Software-Defined Perimeter (SDP): Creates secure, encrypted connections between users and resources, hiding resources from unauthorized users.
Virtual Private Network (VPN): Encrypts data traffic to secure remote connections.
Application Security:
Application Whitelisting: Allows only approved applications to run on the network.
Runtime Application Self-Protection (RASP): Protects applications from threats during runtime.
Secure Software Development Lifecycle (SDLC): Incorporates security into every phase of software development.
Data Security:
Data Encryption: Protects data at rest and in transit using encryption techniques.
Data Loss Prevention (DLP): Prevents unauthorized data transfer and leakage.
Access Control: Implements policies to ensure only authorized users can access sensitive data.
Security Analytics and Threat Detection:
Security Information and Event Management (SIEM): Collects and analyzes security-related data from various sources to detect and respond to threats.
User and Entity Behavior Analytics (UEBA): Uses machine learning to identify unusual behavior that may indicate a threat.
Intrusion Detection and Prevention Systems (IDPS): Monitors network traffic for signs of malicious activity and takes action to prevent breaches.
Automation and Orchestration:
Security Orchestration, Automation, and Response (SOAR): Automates and coordinates security operations to improve response times and efficiency.
Policy Enforcement: Uses automated policies to ensure consistent security measures across the network.
Continuous Monitoring and Assessment:
Continuous Compliance Monitoring: Ensures that the network complies with security policies and regulatory requirements.
Vulnerability Management: Regularly scans for and addresses vulnerabilities in the network and systems.
Penetration Testing: Simulates attacks to identify and address weaknesses.
Implementing a Zero Trust architecture involves integrating these components to create a comprehensive, layered security strategy that continuously verifies and enforces security at every level of the network.
