CompTIA SY0-701 Based on Real Exam Environment

Software-defined networking (SDN) enables microsegmentation by allowing administrators to create fine-grained, dynamic network segments at the software layer independent of physical network topology. This capability isolates workloads and controls traffic flows between segments, enhancing security within data centers and cloud environments.

Next-generation firewalls (A) provide advanced filtering and inspection but do not inherently deliver the granular segmentation flexibility of SDN. Embedded systems (C) and air-gapped systems (D) refer to specific hardware or physical isolation techniques but do not implement microsegmentation as a network control method.

The concept of microsegmentation through SDN is detailed in the Security Architecture domain of the SY0-701 exam【6:Chapter 3†CompTIA Security+ Study Guide】.

Counterfeit hardware is hardware that is built or modified without the authorization of the original equipment manufacturer (OEM). It can pose serious risks to network quality, performance, safety, and reliability12. Counterfeit hardware can also contain malicious components that can compromise the security of the network and the data that flows through it3. To address the risks associated with procuring counterfeit hardware, a company should conduct a thorough analysis of the supply chain, which is the network of entities involved in the production, distribution, and delivery of the hardware. By analyzing the supply chain, the company can verify the origin, authenticity, and integrity of the hardware, and identify any potential sources of counterfeit or tampered products. A thorough analysis of the supply chain can include the following steps:

Establishing a trusted relationship with the OEM and authorized resellers

Requesting documentation and certification of the hardware from the OEM or authorized resellers

Inspecting the hardware for any signs of tampering, such as mismatched labels, serial numbers, or components

Testing the hardware for functionality, performance, and security

Implementing a tracking system to monitor the hardware throughout its lifecycle

Reporting any suspicious or counterfeit hardware to the OEM and law enforcement agencies References = 1: Identify Counterfeit and Pirated Products - Cisco, 2: What Is HardwareSecurity?

Detailed Explanation:

Tokenization replaces sensitive data with non-sensitive surrogate values that retain the necessary format but are meaningless without access to the original data. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 3: Security Architecture, Section: "Data Masking and Tokenization"​​.
