CompTIA SY0-701 Questions Answers

Attempting to enter an unauthorized area using an access badge during a penetration test is an example of a physical test. This type of test evaluates the effectiveness of physical security controls, such as access badges, security guards, and locks, in preventing unauthorized access to restricted areas.

Defensive and offensive testing typically refer to digital or network-based penetration testing strategies.

Passive testing involves observing or monitoring but not interacting with the environment​​.

The best answer is A. Data masking.

When production data is copied into a UAT (User Acceptance Testing) environment, sensitive information should be protected so that testers cannot view real confidential values such as personal data, account numbers, or other regulated information. Data masking replaces sensitive data with realistic but fictional or hidden values while preserving the format and usability of the data for testing.

This makes it ideal for non-production environments where the application still needs data that looks real, but the testing team should not be able to see actual sensitive information.

Why the other options are incorrect:

B. Data tokenizationTokenization replaces sensitive values with tokens, but it is more commonly used to protect data in operational processing systems, such as payment environments. It is not the best fit here compared with masking for UAT visibility concerns.

C. Data obfuscationObfuscation is a broader term and can mean making data harder to understand, but data masking is the more precise and standard control for protecting test data from being viewed.

D. Data encryptionEncryption protects data at rest or in transit, but once authorized testers access and use the UAT system, the application may decrypt and display the data. That does not solve the problem of testers viewing sensitive values.

From a Security+ perspective, when moving production data into development, test, or UAT environments, the preferred control to prevent exposure of real sensitive data is data masking.

Segmentation is a technique that divides a network into smaller subnetworks or segments, each with its own security policies and controls. Segmentation can help mitigate network access vulnerabilities in legacy loT devices by isolating them from other devices and systems, reducing their attack surface and limiting the potential impact of a breach. Segmentation can also improve network performance and efficiency by reducing congestion and traffic. Patching, insurance, and replacement are other possible strategies to deal with network access vulnerabilities, but they may not be feasible or effective in the short term. Patching may not be available or compatible for legacy loT devices, insurance may not cover the costs or damages of a cyberattack, and replacement may be expensive and time-consuming.

Steganography is the process of hiding information within another medium, such as an image, audio, video, or text file. The hidden information is not visible or noticeable to the casual observer, and can only be extracted by using a specific technique or key. Steganography can be used for various purposes, such as concealing secret messages, watermarking, or evading detection by antivirus software12
