Study Notes

VPNs and Secure Access

SDP can replace or coexist with VPNs, offering flexible deployment models.
Both require client installation on user devices, but SDP enables a single access control platform for diverse user environments.
SDPs provide zero visibility through SPA and dynamic firewalls, making them more resilient to cyber attacks compared to traditional VPNs.

Identity and Access Management (IAM)

SDP integrates with enterprise IAM providers across various environments (cloud, on-premises, hybrid).
IAM centralizes validation, authentication, and authorization for users and devices.
Supports standard protocols: LDAP, Active Directory (AD), and SAML for access control.

Access Control Mechanisms

Access control in SDP is based on business rules using IAM attributes and device/network characteristics.
Telemetry data allows for granular access rules to regulate resource accessibility.
Step-up authentication (e.g., one-time passwords) can be initiated for sensitive resource access.

User Authentication and Audit Logging

IAM data serves to enhance the SDP controller's authorization decision-making.
Correlates application access with user activity, yielding detailed audit logs with less overhead.
Supports security and compliance audits by simplifying historical access record assessments.

Identity Lifecycle Management

IAM tools manage the identity lifecycle processes (joiners, movers, leavers - JML).
Role-based and attribute-based access control methods manage resource access.
SDP automatically updates access permissions based on changes in user attributes or group memberships.

Integration with Open Authentication Protocols

SDP works with open protocols like SAML for identity and MFA authentication.
Role and attribute-based access policies are facilitated, lowering complexity compared to traditional models.
Connection-based security ensures access is granted per individual connection rather than IP address.

Centralized IAM Security

A security flaw requires a singular update to SDP, streamlining maintenance across multiple services.
Traditional direct access increases complexity; SDP mitigates this by ensuring strict access control measures are in place.
Attack surface reduction occurs through pre-validation of user/device connections prior to resource access.

Fine-Grained Access Control

SDP architecture operates on comprehensive security principles, employing drop-all gateways for initial authentication.
Connectivity to resources is only established after successful authentication and authorization.
Malicious connection attempts are promptly thwarted through immediate packet denial at the perimeter.

Control and Data Plane Separation

SDP architecture consists of three planes: data plane, control plane, and management plane.
Data plane manages user traffic; control plane oversees connection establishment and packet authorization.
Users and devices gain access to the data plane only after validation at the control plane, enhancing security.

Mutual Transport Layer Security (mTLS)

mTLS secures client-server traffic ensuring trusted communication in both directions.
Essential for securing access requests from non-identity provider-logged devices like IoT, allowing resource access validation.
