Study Notes
Authentication Protocols
- SDP integrates with open authentication protocols such as SAML, OAuth, OpenID Connect, W3C Web Authentication, and FIDO Alliance Client-to-Authenticator Protocol.
- These protocols enhance the flexibility and security of user access but are beyond the current training scope.
Next Generation Firewall (NGFW)
- NGFWs combine traditional firewall functions with advanced features like intrusion detection/prevention and deep packet inspection.
- They operate across OSI model layers 2 through 7, enabling comprehensive monitoring and filtering of network traffic.
- Key capabilities of NGFWs include:
- Application Awareness: Identifies applications to anticipate potential threats.
- Intrusion Detection/Prevention System (IDPS): Monitors and reacts to network security breaches.
- Identity Awareness: Manages user access to resources.
- VPN: Facilitates secure remote access.
Limitations of NGFWs
- Latency: Network latency increases, especially during file inspections.
- Scalability Issues: Requires more powerful hardware as demand scales up.
- Rule Complexity: Identity management features may complicate implementation.
Integration of SDP and NGFW
- SDP complements NGFWs by enforcing secure user access while maintaining core firewall capabilities.
- Combining SDP with NGFWs enables dynamic user access policies, enhancing security and reducing visibility.
- NGFWs are IP-based with limited identity capabilities, while SDP is connection-based, allowing for better control of authorized connections.
- SDP supports more dynamic and distributed network architectures, contrasting with the perimeter-centric approach of traditional NGFWs.
Network Access Control (NAC)
- NAC controls device connectivity to networks and specific locations, historically relying on IP address-based methods.
- SDP enhances security by being IP address agnostic and securing connections without relying on IPs for access authorization.
Virtual Private Network (VPN)
- VPNs securely connect private networks over untrusted channels, crucial for safe remote user access.
Threat Mitigation through SDP
- SDP features bolster application security against various threats like DoS/DDoS attacks, code injection exploits, and server misconfigurations.
- Encryption, pinned certificates, and dynamic security measures protect against connection hijacking threats (e.g., MITM attacks, DNS poisoning).
General Security Controls Integration Challenges
- Integrating multiple security controls (e.g., firewalls, identity managers) is essential for compliance but can be complex.
- Achieving cohesive protection requires gathering and correlating information from user activity, network status, and device details, complicating the security management landscape.
