Physically uncloneable functions (PUFs) are hardware-based features that leverage intrinsic physical properties of chips to create unique, non-reproducible identifiers. This reduces supply chain risks by enabling robust authentication and counterfeit prevention. This method aligns withCASP+ objective 4.3, which focuses on secure hardware design and supply chain risk management, ensuring authenticity and integrity of hardware components.

The best way to achieve the objective of discovering SaaS applications and blocking access to unapproved or identified as risky ones is to implement cloud infrastructure to proxy all user web traffic and control access according to centralized policy (C). This solution would allow the security architect to inspect all web traffic and enforce access control policies centrally. This solution also allows the security architect to detect and block risky SaaS applications.

Deception software is a technology that creates realistic but fake assets (such as servers, applications, data, etc.) that mimic the real environment and lure attackers into interacting with them. By doing so, deception software can help detect advanced persistent threats (APTs) that may otherwise evade traditional security tools12. Deception software can also provide valuable insights into the attacker’s tactics, techniques, and procedures (TTPs) by capturing their actions and behaviors on the decoys13.

Deception software can meet the customer’s requirements for security capabilities because:

It is capable of early detection of APTs by creating attractive targets for them and alerting security teams when they are engaged12.

It is transparent to users and causes no performance degradation because it does not interfere with legitimate traffic or resources13.

It allows integration with production and development networks seamlessly because it can create decoys that match the network topology and configuration13.

It enables the security team to hunt and investigate live exploitation techniques because it can record and analyze the attacker’s activities on the decoys13.

"Differential fault analysis (DFA) is a type of active side-channel attack in the field of cryptography, specifically cryptanalysis. The principle is to induce faults—unexpected environmental conditions—into cryptographic operations, to reveal their internal states."

A remote desktop gateway server is a solution that allows users to connect to remote desktops or applications over the internet using the Remote Desktop Protocol (RDP). A remote desktop gateway server can enforce MFA for RDP by integrating with Azure AD MFA using theNetwork Policy Server (NPS) extension. The NPS extension can send an OTP (one-time password) to the user’s phone or mobile app as a second factor of authentication. A remote desktop gateway server can also enforce secure ciphers by configuring the SSL Cipher Suite Order Group Policy setting to specify the preferred order of cipher suites for TLS/SSL connections.
