Study Notes

Protect Surface and Attack Surface

The protect surface is stable and constant, unlike the expanding attack surface.
Identification of data, assets, and critical services is essential for establishing a protect surface.
Proximity of controls to critical assets minimizes risks like lateral privilege escalation and network visibility.

Cybersecurity Risks

Successful compromise of entry points can lead to cardholder data or Personally Identifiable Information (PII) being exploited.
Protect surfaces enable organizations to enforce security measures, such as role-based access control (RBAC) and system hardening, closer to critical assets.

Server Security Measures

Hardening base server images before deployment enhances security.
Separating web servers from database hosts reduces vulnerability to attacks.

Micro-segmentation and Zero Trust

Organizations can create multiple protect surfaces through micro-segmentation in alignment with NSTAC’s definition of protect surfaces.

Attack Vectors and Mitigations

Attack surface includes information flow vulnerabilities between components like Policy Enforcement Point (PEP), Policy Decision Point (PDP), and Policy Information Point (PIP).
Employing TLS certificates and mutual TLS (mTLS) can mitigate man-in-the-middle attacks and ensure two-way authentication.

Malicious Insider Threats

Policies on PIP/PEP/PDP can be tampered with by insiders, necessitating background checks and strong access controls.
Logging and sharing of logs with customers can help mitigate risks from insider threats.

Role-Based Access Control (RBAC)

Implementing network segmentation allows tailored access to sensitive information, e.g., trade secrets for designated personnel only.
Zero Trust Architecture (ZTA) ensures device verification to preempt malicious movements from compromised credentials.

Remote Access Challenges

Remote access encompasses various users, increasing the potential for lateral movement via compromised credentials.
Use of Virtual Desktop Infrastructure (VDI) and corporate cloud resources helps mitigate remote access risks.

Device Authentication

Device authentication reduces the attack surface by ensuring only authorized users access specific resources.
Integration of multifactor authentication (MFA) enhances security with behavior analysis and geofencing approaches.

Mobile Device Security

Organizations often implement services accessible from mobile devices, stressing the need for robust security measures to protect sensitive data on these platforms.
