Input sanitization is a critical security measure to prevent SQL injection attacks, which occur when an attacker exploits vulnerabilities in a website's input fields to execute malicious SQL code. By properly sanitizing and validating all user inputs, developers can prevent malicious code from being executed, thereby securing the website against such attacks.

Hashing is used to verify data integrity. By comparing the hash value of the data before and after transmission, it is possible to determine if the data has been altered in transit. If the hash values match, the data has not been modified.

Environmental variables store configuration settings, paths, and other system-related information that applications and processes use. If an attacker gains access to these variables, they could manipulate them to alter application behavior, gain unauthorized access, or escalate privileges.For example, an attacker could modify the PATH variable to execute malicious programs instead of legitimate ones. This can significantlyincrease the scope and impact of an exploited vulnerability, making it a major security concern.

A Cloud Access Security Broker (CASB) solution is the most suitable option for securing an organization that has adopted a cloud-first strategy and does not have an on-premises IT infrastructure. CASBs provide visibility and control over shadow IT services, enforce security policies, and protect data across cloud services.

Containers are a method of virtualization that allows applications to run in isolated environments with their own dependencies, libraries, and configurations. Containers are best suited for constantly changing environments because they are lightweight, portable, scalable, and easy to deploy and update. Containers can also support microservices architectures, which enable faster and more frequent delivery of software features. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 10: Mobile Device Security, page 512 1

Detailed Explanation:Host isolation ensures that a device is separated from the network, preventing it from accessing or being accessed by other network resources. This is typically achieved by quarantining the device. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Isolation and Containment"​​.

 An ISOW is a document that outlines the project, the cost, and the completion time frame for a security company to provide a service to a client. ISOW stands for Information Security Operations Work, and it is a type of contract that specifies the scope, deliverables, milestones, and payment terms of a security project. An ISOW is usually used for one-time or short-term projects that have a clear and defined objective and outcome. For example, an ISOW can be used for a security assessment, a penetration test, a security audit, or a security training.

The other options are not correct because they are not documents that outline the project, the cost, and the completion time frame for a security company to provide a service to a client. A MSA is a master service agreement, which is a type of contract that establishes the general terms and conditions for a long-term or ongoing relationship between a security company and a client. A MSA does not specify the details of each individual project, but rather sets the framework for future projects that will be governed by separate statements of work (SOWs). A SLA is a servicelevel agreement, which is a type of contract that defines the quality and performance standards for a security service provided by a security company to a client. A SLA usually includes the metrics, targets, responsibilities, and penalties for measuring and ensuring the service level. A BPA is a business partnership agreement, which is a type of contract that establishes the roles and expectations for a strategic alliance between two or more security companies that collaborate to provide a joint service to a client. A BPA usually covers the objectives, benefits, risks, and obligations of the partnership. References = CompTIA Security+ Study Guide (SY0-701), Chapter 8: Governance, Risk, and Compliance, page 387. Professor Messer’s CompTIA SY0-701 Security+ Training Course, Section 8.2: Compliance and Controls, video: Contracts and Agreements (5:12).

Detailed Explanation:Proper data sanitization ensures that sensitive data is securely erased from storage devices, preventing unauthorized access or recovery when the devices are disposed of or reused. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Data Sanitization and Disposal Methods"​​.

Full Disk Encryption (FDE) ensures that all data on the drive is encrypted, preventing unauthorized access even if the device is lost.
