Aprocedureprovides step-by-step instructions on how to complete a specific security task, ensuring consistency and accuracy. Unlike policies, which define high-level security expectations,procedures are detailed and operational. For example, apassword reset procedurewould outline the exact steps IT support must follow when assisting users.

Policy: Defines security objectives and rules (e.g., "All passwords must be complex").

Standard: Specifies required technologies or configurations.

Guideline: Provides recommendations but is not mandatory.

Procedure: Gives exact instructions to perform tasks.

Multi-Factor Authentication (MFA) and patch management are both examples of preventative and technical controls. MFA prevents unauthorized access by requiring multiple forms of verification, and patch management ensures that systems are protected against vulnerabilities by applying updates. Both of these controls are implemented using technical methods, and they work to prevent security incidents before they occur.

When hosting an on-premises software application in a cloud-based service, ensuring visualization and isolation of resources is crucial for maintaining security best practices. This involves using virtualization techniques to create isolated environments (e.g., virtual machines or containers) for different applications and services, reducing the risk of cross-tenant attacks or resource leakage.

Network segmentation is important but pertains more to securing network traffic rather than isolating computing resources.

Data encryption is also essential but doesn’t specifically address resource isolation in a cloud environment.

Strong authentication policies are critical for access control but do not address the need for isolating resources within the cloud environment​​.

The described activity—visiting a website and downloading publicly accessible content—is a classic example of passive reconnaissance. Passive reconnaissance involves gathering information about a target without interacting with its internal systems or generating traffic that could be detected by security monitoring tools.

According to SY0-701, passive recon uses open-source intelligence (OSINT), such as:

Public websites

DNS records

News articles

Metadata

Public document repositories

The key distinction is that passive reconnaissance does not probe the system for vulnerabilities, nor does it send active scanning traffic.

Vulnerability scanning (B) requires active probing. Unknown environment testing (A) applies to black-box testing but still may involve active scanning. Due diligence (C) refers to risk assessment or compliance reviews, not technical reconnaissance.

Therefore, downloading the website’s content is a non-intrusive information-gathering technique, perfectly matching passive reconnaissance as defined in the exam materials under Threats, Vulnerabilities, Attack Vectors, and Pen Testing Phases.

A tabletop exercise is a discussion-based exercise where stakeholders gather to walk through the roles and responsibilities they would have during a specific situation, such as a security incident or disaster. This type of exercise is designed to identify gaps in planning and improve coordination among team members without the need for physical execution.

 Password spraying is a type of brute force attack that tries common passwords across several accounts to find a match. It is a mass trial-and-error approach that can bypass account lockout protocols. It can give hackers access to personal or business accounts and information. It is not a targeted attack, but a high-volume attack tactic that uses a dictionary or a list of popular or weak passwords12.

The logs show that the attacker is using the same password ("password123") to attempt to log in to different accounts ("admin", "user1", "user2", etc.) on the same web server. This is a typical pattern of password spraying, as the attacker is hoping that at least one of the accounts has a weak password that matches the one they are trying. The attacker is also using a tool called Hydra, which is one of the most popular brute force tools, often used in cracking passwords for network authentication3.

Account forgery is not the correct answer, because it involves creating fake accounts or credentials to impersonate legitimate users or entities. There is no evidence of account forgery in the logs, as the attacker is not creating any new accounts or using forged credentials.

Pass-the-hash is not the correct answer, because it involves stealing a hashed user credential and using it to create a new authenticated session on the same network. Pass-the-hash does not require the attacker to know or crack the password, as they use the stored version of the password to initiate a new session4. The logs show that the attacker is using plain text passwords, not hashes, to try to log in to the web server.

Brute-force is not the correct answer, because it is a broader term that encompasses different types of attacks that involve trying different variations of symbols or words until the correct password is found. Password spraying is a specific type of brute force attack that uses a single common password against multiple accounts5. The logs show that the attacker is using password spraying, not brute force in general, to try to gain access to the web server. References = 1: Password spraying: An overview of password spraying attacks … - Norton, 2: Security: Credential Stuffing vs. Password Spraying - Baeldung, 3: Brute ForceAttack: A definition + 6 types to know | Norton, 4: What is a Pass-the-Hash Attack? - CrowdStrike, 5: What is a Brute Force Attack? | Definition, Types & How It Works - Fortinet

 Analysis is the incident response activity that describes the process of understanding the source of an incident. Analysis involves collecting and examining evidence, identifying the root cause, determining the scope and impact, and assessing the threat actor’s motives and capabilities. Analysis helps the incident response team to formulate an appropriate response strategy, as well as to prevent or mitigate future incidents. Analysis is usually performed after detection and before containment, eradication, recovery, and lessons learned. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 6, page 223.

Comprehensive and Detailed In-Depth Explanation:

Operating system (OS) vulnerabilitiescan allow attackers to exploit system functions that affect multiple applications, leading towidespread compromise.

B (patch cycle concerns)is valid but not the primary concern—many OS vendors provide regular patches.

C (user trust in OS features)is a risk, but the more significant issue is thatOS vulnerabilities often affect multiple system components.

D (ease of exploitation)is not always true, as application and human-related vulnerabilities can be equally exploitable.

Thus,the main concern is that an OS exploit can impact multiple system functions, leading to broader security risks.

Static analysis is the process of examining a file without executing it to identify known malicious signatures, suspicious patterns, strings, embedded resources, or code fragments. When a security engineer needs to quickly extract a signature from a known malicious file, static analysis is the most efficient approach. This method allows analysts to inspect binary code, metadata, file headers, and hashes such as MD5/SHA-256.

According to Security+ SY0-701, static analysis is ideal for identifying:

Malware signatures

Embedded malicious payloads

Hash values for detection

Known indicators of compromise (IOCs)

Sandboxing (B) is used to observe behavior by executing the malware, which takes longer and is unnecessary when the malware is already known. Network traffic analysis (C) is used to observe communications, not generate file signatures. Package monitoring (D) refers to monitoring OS-level changes and system calls, which is a dynamic method.

Static analysis aligns with the requirement for quick identification, making option A the correct choice.

A supply chain vendor is a third-party entity that provides goods or services to an organization, such as a SaaS provider. A supply chain vendor can pose a risk to the new system if the vendor has poor security practices, breaches, or compromises that could affect the confidentiality, integrity, or availability of the system or its data. The organization should perform due diligence and establish a service level agreement with the vendor to mitigate this risk. The other options are not specific to the scenario of using a SaaS provider, but rather general risks that could apply to any system.

Cryptojacking is the likely cause in this scenario. It involves malware that hijacks the resources of infected computers to mine cryptocurrency, usually without the user's knowledge. This type of attack doesn't typically degrade performance significantly or result in obvious system failures, which matches the situation described, where the machines showed no signs of degraded performance or excessive failed logins.

A data retention policy is a set of rules that defines how long data should be stored and when it should be deleted or archived. An administrator assists the legal and compliance team with ensuring information about customer transactions is archived for the proper time period by following the data retention policy of the organization. This policy helps the organization to comply with legal and regulatory requirements, optimize storage space, and protect data privacy and security.

Comprehensive and Detailed Explanation From Exact Extract:

Non-repudiation ensures that a sender cannot deny sending a message. Digital signatures provide non-repudiation because they use the sender’s private key, which only the legitimate owner possesses. When the email recipient verifies the digital signature using the sender’s public key, it proves the email was sent by the true owner of the private key and has not been altered.

Confidentiality (B) ensures information is protected from unauthorized access and is usually achieved through encryption. Integrity (C) ensures data has not been modified, while authentication (D) verifies the identity of a user. Although digital signatures also support integrity and authentication, the specific property that prevents denial of sending the email is non-repudiation.

Security+ SY0-701 highlights digital signatures as a cryptographic mechanism used for authentication, integrity, and non-repudiation, especially in email security, PKI systems, and secure messaging.

Thus, the correct answer is Non-repudiation.
