SY0-701 Exam Dumps - CompTIA Security+ Exam 2026

The correct answer is A. ICS.

ICS stands for Industrial Control Systems. These systems are commonly used in industrial environments such as manufacturing, energy, utilities, water treatment, transportation, and critical infrastructure. ICS environments often use proprietary protocols, specialized hardware, and legacy systems. They are designed to operate reliably for many years, sometimes in harsh physical environments, and may have limited remote management capabilities.

This aligns with CompTIA Security+ SY0-701 topics involving specialized systems, operational technology, embedded systems, and industrial control system security.

Why the other options are incorrect:

B. Microservers

Microservers are small, low-power servers used for lightweight workloads. They are not specifically associated with proprietary industrial controls or harsh operating environments.

C. Containers

Containers are lightweight application environments used to package and run software. They are not designed specifically for long-term industrial control in harsh environments.

D. IoT

Internet of Things devices can be embedded and may operate in many environments, but the description of proprietary controls, harsh environments, long operational lifespans, and limited remote management best matches ICS.

Therefore, the correct answer is ICS.

Purple is the team that combines both offensive and defensive testing techniques to protect an organization’s critical systems. Purple is not a separate team, but rather a collaboration between the red team and the blue team. The red team is the offensive team that simulates attacks and exploits vulnerabilities in the organization’s systems. The blue team is the defensive team that monitors and protects the organization’s systems from real and simulated threats. The purple team exists to ensure and maximize the effectiveness of the red and blue teams by integrating the defensive tactics and controls from the blue team with the threats and vulnerabilities found by the red team into a single narrative that improves the overall security posture of the organization. Red, blue, and yellow are other types of teams involved in security testing, but they do not combine both offensive and defensive techniques. The yellow team is the team that builds software solutions, scripts, and other programs that the blue team uses in the security testing. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 1331; Penetration Testing: Understanding Red, Blue, & Purple Teams3

The correct answer is B. Code signing.

Code signing uses a digital signature to verify the authenticity and integrity of software, scripts, drivers, or compiled binaries. If a compiled binary is signed, the production environment can verify that the binary came from a trusted source and has not been modified since it was signed.

This supports integrity because any unauthorized change to the binary would invalidate the signature.

Why the other options are incorrect:

A. Input validation

Input validation helps prevent attacks such as injection, cross-site scripting, and malformed input attacks. It does not verify the integrity of compiled binaries.

C. SQL injection

SQL injection is an attack technique, not a security measure.

D. Static analysis

Static analysis reviews source code or binaries without executing them. It can help identify vulnerabilities before deployment, but it does not provide ongoing integrity verification of compiled binaries in production.

Therefore, the best answer is code signing.

ALE (Annualized Loss Expectancy) is the risk management metric most helpful when deciding whether the licensing cost of a ransomware prevention solution is justified. ALE calculates the expected yearly financial loss from a particular threat. It is computed as:

ALE = SLE × ARO

SLE (Single Loss Expectancy) estimates the monetary impact of one ransomware incident.

ARO (Annualized Rate of Occurrence) estimates how often the incident is expected to happen each year.

By comparing ALE to the annual licensing cost of the new security solution, the organization can make a financially informed decision based on cost-benefit analysis. If ALE exceeds the solution’s cost, the purchase is justified.

RTO (C) relates to recovery time after outages, not cost justification. SLE (B) is only part of the calculation and insufficient alone. ARO (D) shows frequency but not financial impact.

Security+ SY0-701 highlights ALE as the primary metric for evaluating security investments.

Thus, ALE is the key factor in determining whether purchasing ransomware protection is financially beneficial.
