Hashing is the correct mechanism for ensuring that a software release has not been modified prior to reaching the end user. Hashing provides integrity verification by generating a fixed-length digest (such as SHA-256) from the original software package. When users download the software, they can compute the hash locally and compare it to the hash value published by the vendor. If the values match, the software has not been altered; if they differ, tampering or corruption has occurred.
CompTIA Security+ SY0-701 emphasizes hashing as a core cryptographic control used to verify integrity for files, updates, patches, and software distributions. Hashing is extremely sensitive to change-altering even a single bit in the file results in a completely different hash value.
Encryption (B) protects confidentiality, not integrity. Tokenization (A) replaces sensitive data with tokens and is unrelated to software integrity. Obfuscation (D) makes code harder to read but does not guarantee it has not been modified.
Therefore, hashing is the most appropriate and reliable method to ensure software integrity before release.

File Integrity Monitoring (FIM) is the best tool for detecting unauthorized file deletions, modifications, or improper permission changes within network shares. FIM works by creating cryptographic hashes and baselines for protected files or directories and then continuously monitoring for deviations. Any unauthorized deletion, modification, or permission change triggers alerts.
Security+ SY0-701 identifies FIM as a foundational integrity control used in compliance frameworks (PCI- DSS, HIPAA) and operational security monitoring. Because the organization is experiencing unpredictable changes to shared files and permissions, FIM provides visibility and accountability for who changed what and when.
DLP (A) prevents data leakage but does not detect permission changes. EDR (B) focuses on endpoint threat behavior, not file integrity on network shares. ACLs (D) define permissions but do not track changes or detect unauthorized modifications.
Therefore, C: FIM is the correct choice.

The employee notices that the links in the email do not correspond to the company's official URLs, indicating that this is likely a social engineering attack. Social engineering involves manipulating individuals into divulging confidential information or performing actions that may compromise security. Phishing emails, like the one described, often contain fraudulent links to trick the recipient into providing sensitive information or downloading malware.
* Business email refers to business email compromise (BEC), which typically involves impersonating a high-level executive to defraud the company.
* Unsecured network is unrelated to the email content.
* Default credentials do not apply here, as the issue is with suspicious links, not login credentials.

Benchmarks provide standardized security configuration baselines or templates (such as CIS Benchmarks) for systems including firewalls. Using benchmarks helps MSSPs apply consistent and secure configurations across many clients efficiently.
SNMP (A) is for network device management, Netflow (C) is for traffic analysis, and SCAP (D) is a framework for vulnerability and compliance management but not directly for template creation.
