CompTIA Security+ SY0-701 Syllabus Exam Questions Answers

To limit the potential impact on the log-in database in case of a breach, the security team would most likely recommend hashing. Hashing converts passwords into fixed-length strings of characters, which cannot be easily reversed to reveal the original passwords. Even if the database is breached, attackers cannot easily retrieve the actual passwords if they are properly hashed (especially with techniques like salting).

Tokenization is used to replace sensitive data with a token, but it is more common for protecting credit card data than passwords.

Obfuscation is the process of making data harder to interpret but is weaker than hashing for password protection.

Segmentation helps isolate data but doesn't directly protect the contents of the login database​​.

Alerts generated by SIEM (Security Information and Event Management) tools are detective controls, as they identify and notify about suspicious activities but do not prevent or correct the events themselves.

Preventive controls stop incidents before they occur, corrective controls remediate issues, and compensating controls are alternatives used when primary controls aren’t feasible.

Detective controls are foundational in Security Operations for incident detection and response【6:Chapter 14†CompTIA Security+ Study Guide】.

An image backup, also known as a full system backup, captures the entire contents of a system, including the operating system, applications, settings, and all data. This type of backup allows for a complete recovery of the system in case of a disaster, as it includes everything needed to restore the system to its previous state. This makes it the ideal choice for a systems administrator who needs to ensure the ability to recover the entire system, including the OS.

Infrastructure as code (IaC) is a method of using code and automation to manage and provision cloud resources, such as servers, networks, storage, and applications. IaC allows for easy deployment, scalability, consistency, and repeatability of cloud environments. IaC is also a key component of DevSecOps, which integrates security into the development and operations processes. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 6: Cloud and Virtualization Concepts, page 294.
