SY0-701 Exam Dumps - CompTIA Security+ Questions and Answers

 An acceptable use policy (AUP) is a set of rules that govern how users can access and use a corporate network or the internet. The AUP helps companies minimize their exposure to cyber security threats and limit other risks. The AUP also serves as a notice to users about what they are not allowed to do and protects the company against misuse of their network. Users usually have to acknowledge that they understand and agree to the rules before accessing the network1.

An AUP best represents a preventive security control type, because it aims to deter or stop potential security incidents from occurring in the first place. A preventive control is proactive and anticipates possible threats and vulnerabilities, and implements measures to prevent them from exploiting or harming the system or the data. A preventive control can be physical, technical, or administrative in nature2.

Some examples of preventive controls are:

Locks, fences, or guards that prevent unauthorized physical access to a facility or a device

Firewalls, antivirus software, or encryption that prevent unauthorized logical access to a network or a system

Policies, procedures, or training that prevent unauthorized or inappropriate actions or behaviors by users or employees

An AUP is an example of an administrative preventive control, because it defines the policies and procedures that users must follow to ensure the security and proper use of the network and the IT resources. An AUP can prevent users from engaging in activities that could compromise the security, performance, or availability of the network or the system, such as:

Downloading or installing unauthorized or malicious software

Accessing or sharing sensitive or confidential information without authorization or encryption

Using the network or the system for personal, illegal, or unethical purposes

Bypassing or disabling security controls or mechanisms

Connecting unsecured or unapproved devices to the network

By enforcing an AUP, a company can prevent or reduce the likelihood of security breaches, data loss, legal liability, or reputational damage caused by user actions or inactions3.

In this scenario, employees are attempting to navigate to spoofed websites, which is being blocked by the web filter. To address this issue, the administrator should implement security awareness training. Training helps employees recognize phishing and other social engineering attacks, reducing the likelihood that they will attempt to access malicious websites in the future.

Deploying multifactor authentication (MFA) would strengthen authentication but does not directly address user behavior related to phishing websites.

Decreasing the level of the web filter would expose the organization to more threats.

Updating the acceptable use policy may clarify guidelines but is not as effective as hands-on training for improving user behavior​​​.

Detailed Explanation:The acquisition phase involves creating forensic images (exact replicas) of storage devices or memory to ensure data integrity for further analysis. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Forensic Imaging and Chain of Custody"​​.

Detailed Explanation:Quarantining a potentially infected system by placing it into an air-gapped environment physically disconnects it from the network. This prevents the spread of malware while maintaining the integrity of forensic evidence. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Incident Response and Containment"​​.

An unknown environment in penetration testing, also known as a black-box test, simulates an actual external attack where the tester has no prior knowledge of the system. This type of penetration test is designed to mimic real-world attack scenarios, where an attacker has little to no information about the target environment. The tester must rely on various reconnaissance and attack techniques to uncover vulnerabilities, much like a real-world attacker would. This approach helps organizations understand their security posture from an external perspective, providing insights into how their defenses would hold up against a true outsider threat.

CompTIA Security+ SY0-701 Course Content: The course highlights the importance of understanding different penetration testing environments, including black-box testing, which aligns with the "unknown environment" in the provided answer.

CompTIA Security+ SY0-601 Study Guide: The guide details penetration testing methodologies, including black-box testing, which is crucial for simulating real external attacks​​​.

Detailed Explanation:

Retention policies dictate how long data must be stored to comply with local and international regulations. Non-compliance can result in legal and financial penalties. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Data Retention and Legal Requirements"​​.

The principle of least privilege is a security concept that limits access to resources to the minimum level needed for a user, a program, or a device to perform a legitimate function. It is a cybersecurity best practice that protects high-value data and assets from compromise or insider threat. Least privilege can be applied to different abstraction layers of a computing environment, such as processes, systems, or connected devices. However, it is rarely implemented in practice.

In this scenario, the IT manager is setting up the principle of least privilege by restricting access to the administrator console of the help desk software to only two authorized users: the IT manager and the help desk lead. This way, the IT manager can prevent unauthorized or accidental changes to the software configuration, data, or functionality by other help desk staff. The other help desk staff will only have access to the normal user interface of the software, which is sufficient for them to perform their job functions.

The other options are not correct. Hardening is the process of securing a system by reducing its surface of vulnerability, such as by removing unnecessary software, changing default passwords, or disabling unnecessary services. Employee monitoring is the surveillance of workers’ activity, such as by tracking web browsing, application use, keystrokes, or screenshots. Configuration enforcement is the process of ensuring that a system adheres to a predefined set of security settings, such as by applying a patch, a policy, or a template.
