Simulado SY0-701: CompTIA CompTIA Security+ Certification Exam

Explanation: Correct answer: D. Salting Salting is the process of adding extra random data to a password or other data before applying a one-way data transformation algorithm, such as a hash function. Salting increases the complexity and randomness of the input data, making it harder for attackers to guess or crack the original data using precomputed tables or brute force methods. Salting also helps prevent identicalpasswords from producing identical hash values, which could reveal the passwords to attackers who have access to the hashed data. Salting is commonly used to protect passwords stored in databases or transmitted over networks.Reference= Passwords technical overview Encryption, hashing, salting -- what's the difference?

Explanation: Correct answer: C. Badge access; D. Access control vestibule Badge access and access control vestibule are two of the best ways to ensure only authorized personnel can access a secure facility. Badge access requires the personnel to present a valid and authenticated badge to a reader or scanner that grants or denies access based on predefined rules and permissions. Access control vestibule is a physical security measure that consists of a small room or chamber with two doors, one leading to the outside and one leading to the secure area. The personnel must enter the vestibule and wait for the first door to close and lock before the second door can be opened.This prevents tailgating or piggybacking by unauthorized individuals.

Explanation: Correct answer: B. The company's SIP server security settings are weak. If cadets are using company phone numbers to make unsolicited calls, and the logs confirm the numbers are not being spoofed, it suggests that the SIP (Session Initiation Protocol) server's security settings might be weak. This could allow unauthorized access or exploitation of the company's telephony services, potentially leading to misuse by unauthorized individuals.

Explanation: Correct answer: B. CVSS Detailed The Common Vulnerability Scoring System (CVSS) is a standardized metric used to assess the severity of vulnerabilities, aiding organizations in prioritizing their response based on risk. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 2: Vulnerabilities, Section: 'Vulnerability Prioritization and Metrics'.

Explanation: Correct answer: D. Due diligence By requesting a SOC 2 report, the analyst is conducting a vendor risk assessment because: SOC 2 Reports:These reports document a vendor's security, availability, processing integrity, G confidentiality, and privacy controls Risk Evaluation:The assessment evaluates whether the SaaS vendor's security practices meet the G company's risk tolerance and requirements Third-Party Vetting:SOC 2 reports are prepared by independent auditors, providing objective verification G of vendor controls Compliance Verification:The report demonstrates the vendor's compliance with security standards G relevant to the industry Due Diligence:Requesting documentation before implementation is part of the due diligence process for G vendor selection Vendor risk assessment is the process of evaluating third-party security posture before integrating their services into the organization.

Explanation: Correct answer: C. Replacing Telnet with SSH Network device hardening is best accomplished by disabling unnecessary services and ports. This reduces the attack surface by eliminating services that are not required for the device's function. Other hardening practices include changing default credentials, updating firmware, applying security patches, and configuring access controls, but disabling unused services and ports directly minimizes the potential vectors available to attackers, making it a primary hardening step.

Explanation: Correct answer: D. The security team created a honeynet. Allowing risky protocols like SMB and RDP from the internet to a controlled VLAN is commonly done to create a honeynet, a deliberately vulnerable network environment used to attract attackers and study their behaviors without risking production systems. Building a file-sharing site (A) or preparing for a pentest (B) typically wouldn't require exposing SMB and RDP broadly. SASE integration (C) focuses on cloud security access and doesn't involve opening such protocols indiscriminately. Honeynets are described as a deception technology in the Security Architecture domain6:Chapter 9CompTIA Security+ Study Guide.

Explanation: Correct answer: C. Shadow IT Using a simulation program that was not properly vetted before deployment is an example of the unvetted or unapproved softwarethreat. This represents a risk where software is deployed without proper security assessment, testing, or approval. Unvetted software can introduce vulnerabilities, malware, or functionality that conflicts with security policies. This is a common threat in organizations where departments bypass standard procurement and security review processes, often referred to as 'shadow IT' risks.

Explanation: Correct answer: B. Update user guidance to include suspicious incident reporting. The best answer is B. Update user guidance to include suspicious incident reporting. The phishing simulation results show that users were not fooled, which means awareness training is already helping them avoid credential theft. However, the employees deleted the email without reporting it. That means the organization missed an opportunity to: investigate the message further identify other recipients block similar messages improve incident response visibility update defensive controls quickly The most valuable next step is to train or guide users to report suspicious emails, not just ignore or delete them.

Explanation: Correct answer: D. Phishing Phishing is a type of social engineering attack that involves sending fraudulent emails that appear to be from legitimate sources, such as payment websites, banks, or other trusted entities. The goal of phishing is to trick the recipients into clicking on malicious links, opening malicious attachments, or providing sensitive information, such as log-in credentials, personal data, or financial details. In this scenario, the employee received an email from a payment website that asked the employee to update contact information. The email contained a link that directed the employee to a fake website that mimicked the appearance of the real one. The employee entered the log-in information, but received a ''page not found'' error message. This indicates that the employee fell victim to a phishing attack, and the attacker may have captured the employee's credentials for the payment website.Reference=Other Social Engineering Attacks -- CompTIA Security+ SY0- 701 -- 2.2,CompTIA Security+: Social Engineering Techniques & Other Attack... - NICCS, [CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition]
