And his name is called Seven Zero One

Implementing Single Sign-On (SSO) (A) is the most suitable authentication protocol for balancing security and accessibility in this scenario. SSO allows employees to access multiple applications, including the new internal application, with a single set of credentials, reducing the complexity of managing multiple passwords while maintaining a secure authentication process. RADIUS (B) is more focused on network access and might not be as streamlined for application access. CHAP (C) is used for network authentication but does not provide the same level of user convenience as SSO. PKI (D) is important for secure communications but may be more complex than necessary for user authentication to an internal application.

The primary difference between Layer 4 and Layer 7 security devices lies in the OSI model layers at which they operate and the type of traffic they manage (Option B). Layer 4 security devices function at the transport layer (Layer 4 of the OSI model) and primarily manage traffic based on TCP/UDP ports and protocols. This level of security is concerned with ensuring the efficient and secure transport of data between hosts. In contrast, Layer 7 security devices operate at the application layer (Layer 7 of the OSI model) and focus on inspecting and managing the content of the traffic, as well as application-specific protocols and services. This includes analyzing HTTP requests, inspecting web content, and enforcing application-level policies. Layer 4 devices do not focus on data encryption (Option A), nor do they provide physical security (Option C), and Layer 7 devices do not handle network routing. Layer 4 and Layer 7 devices are not identical in functionality (Option D), as they target different aspects of network traffic and security.

In the scenario where a staff member forgets to deactivate a pressure-sensitive security system in a jewelry store display case, the system should respond by sounding an alarm and notifying store management (Option B). This response is appropriate for a security system designed to prevent theft by detecting the unauthorized removal of items. Even though the removal is by a staff member, the system operates on the principle that any removal without deactivation is unauthorized. Temporarily disabling the alarm (Option A) or allowing the removal without triggering the alarm (Option C) would compromise the security of the display case. Locking down the store (Option D) might be an excessive response to a single unauthorized removal, especially if it can be quickly resolved by store management.

In an SDN environment, the SDN controllers are the central point of network management and control, making them a critical component to secure. Implementing robust authentication and access controls for the SDN controllers (Option D) is essential to protect against unauthorized access and potential attacks. This ensures that only authorized personnel can modify network configurations and policies, thereby maintaining the integrity and security of the entire network. While strong encryption for data-in-transit (Option B) is important, it does not directly address the risks associated with the centralization of network control in SDN. Reverting to traditional networking methods for sensitive data (Option A) may undermine the benefits of SDN. Deploying additional physical routers and switches (Option C) does not enhance the security of the SDN controllers and may add unnecessary complexity.

The physical security assessment specifically identified the absence of surveillance cameras in critical areas of the data center. To address this vulnerability, the immediate and most appropriate action is to install surveillance cameras in these areas (Option B). This enhances security by allowing monitoring of critical areas and deterring unauthorized access. Implementing biometric access controls (Option A) is an effective security measure but does not address the specific issue of surveillance. Regular security awareness training for staff (Option C) is important for overall security culture but is not a direct response to the lack of surveillance cameras. Upgrading firewall and network security systems (Option D) improves cybersecurity but does not address the physical security concerns identified in the assessment.

The first action when acquiring data from a mobile device in a forensic investigation is to place the device in airplane mode (Option B). This prevents any remote access, data alteration, or wiping commands that could compromise the evidence. It is crucial to preserve the current state of the device and its data before any acquisition or analysis begins. Connecting the device to a network (Option A) or starting data extraction immediately (Option D) may expose it to potential alterations. Performing a factory reset (Option C) would completely erase the data and is counterproductive to the acquisition process.

Establishing a process for verifying the authenticity of callers (C) is the security practice that could have prevented this vishing attack. By having a protocol in place to confirm the identity of callers before providing sensitive information or access, employees can better protect against vishing attempts. This protocol might include calling back through a known official number, using pre-arranged questions or codes, or confirming the request through alternative communication channels. While conducting regular security awareness training (B) is important, it needs to be coupled with specific procedures like caller verification. Implementing strong password policies (A) and using caller ID verification (D) are valuable security measures, but they are less effective in situations where attackers use social engineering to gain direct access or information, as in this vishing scenario.

The GDPR emphasizes the importance of lawfulness, fairness, and transparency in data processing activities. A key aspect of this principle is obtaining clear and affirmative consent from individuals before collecting and processing their personal data. The lack of a clear consent mechanism in the multinational corporation's practices signifies a breach of this principle, as it fails to ensure lawful, fair, and transparent handling of user data. Data minimization (Option A) relates to collecting only necessary data, while integrity and confidentiality (Option C) focus on securing the data. Accountability (Option D) is about demonstrating compliance with GDPR, but the specific issue in this scenario is related to the principle of lawfulness, fairness, and transparency.

This type of cyber attack is known as brand impersonation (B), where attackers create fake websites or send emails that closely mimic legitimate businesses to deceive individuals into providing sensitive information. In this scenario, the attacker used a fraudulent email that appeared to be from a well-known online retailer, along with a website that mimicked the retailer's official site, to trick the consumer into revealing personal and credit card information. Brand impersonation exploits the trust that consumers place in established brands to carry out phishing or other types of fraud. This differs from ransomware (A), which involves encrypting a victim's data and demanding payment, DDoS attacks (C), which overwhelm a system with traffic, and insider threats (D), which involve malicious activities by individuals within an organization.

For a data center providing critical services, implementing redundant power supply systems, including backup generators and uninterruptible power supplies (UPS) (Option B), is crucial for protecting against power outages and ensuring uninterrupted operation. Redundant power systems provide an alternative power source in the event of a failure or disruption in the primary power supply, maintaining the availability of services and preventing data loss or downtime. Deploying additional servers (Option A), upgrading network bandwidth (Option C), and expanding physical space (Option D) are important for capacity and performance but do not directly address the power-related risks and the need for uninterrupted operation.

For enhancing the security of an email server, especially for SMTP with TLS, selecting the correct port is essential. Option A, Port 110, is used for POP3 (Post Office Protocol 3) and is not suitable for SMTP traffic. Option B, Port 143, is used for IMAP (Internet Message Access Protocol) and, like Port 110, is not designed for SMTP. Option D, Port 80, is the standard port for HTTP and is not appropriate for secure email transmission. The most suitable port for secure SMTP transmission with TLS is Option C, Port 587. Port 587 is recommended for SMTP submission and is specifically designed to work with client-to-server email submissions, particularly when using TLS for encryption. This port ensures that emails are transmitted securely, thereby enhancing the overall security of the email server.

Key escrow is a process where encryption keys are securely held by a third party or a dedicated system within an organization, allowing authorized personnel to access these keys under specific circumstances. In this scenario, when an employee who had access to sensitive data leaves the organization, key escrow enables the IT department to access the encryption keys used by the employee. This access is crucial for scenarios where data needs to be decrypted for continuity of care, audits, or legal reasons. The key escrow system ensures that the organization can maintain the security and accessibility of encrypted patient data, even when individual employees who had access to that data are no longer with the organization.

The scenario indicates a failure in enforcing security policies regarding access to cloud storage, which is primarily the responsibility of the automated guard rails. If these guard rails are not properly configured to enforce access controls, they may not effectively restrict public access to sensitive data stored in cloud buckets. This oversight can lead to the kind of security lapse mentioned in the audit. Option A, while important, does not directly address the issue of enforcing security policies through automation. Option B is more related to network security, and Option D focuses on endpoint security, neither of which directly relates to the enforcement of access controls on cloud storage.

Load balancing is the appropriate technology for dynamically distributing incoming web traffic, especially in scenarios with variable traffic. It helps in efficiently managing the load by distributing incoming network traffic across multiple servers, preventing any single server from becoming a bottleneck. This ensures that the web application remains responsive even during traffic surges. Clustering, while beneficial for high availability and fault tolerance, does not primarily focus on traffic distribution. Therefore, in the context of efficiently managing variable traffic and preventing server overburdening, option A, Load Balancing, is the correct answer.

Two-factor authentication (2FA) involves using two different types of authentication methods for verifying a user's identity. In this case, the organization is combining something the user knows (password) with something the user has (smart card). This approach greatly enhances security by adding an extra layer of defense. If a password is compromised, the attacker still needs the smart card to gain access, making unauthorized access significantly more difficult. 2FA is a practical and effective way to strengthen security, especially in response to incidents involving weak or compromised passwords.

The role of a Policy Administrator includes ensuring that security policies comply with relevant laws, regulations, and standards. In this scenario, when an employee suggests a policy change that conflicts with new industry regulations, the Policy Administrator should reject the suggestion and provide an explanation of the regulatory requirements. This action ensures that the company's security policies remain compliant with the regulations, which is a key responsibility of the Policy Administrator. Implementing the suggested change (Option A), forwarding it for technical review (Option C), or adopting it in non-regulated areas (Option D) are not appropriate actions, as they may lead to non-compliance with the regulations.

The most important consideration in this scenario is to select an antivirus solution that is compatible with the diverse range of operating systems and hardware configurations present in the network. This ensures that the antivirus software can be seamlessly integrated and function effectively across all systems, providing consistent protection throughout the network. While detection rate (Option A), cost (Option C), and scanning speed (Option D) are important factors, compatibility is crucial for ensuring that the antivirus software works properly on every system in the diverse environment.

For an e-commerce company experiencing frequent traffic surges, the most important security consideration is enhancing server capacity to handle increased traffic without compromising security (Option B). This involves scaling up resources to ensure that the website remains responsive to customer demands while maintaining robust security measures to protect against potential threats. Temporarily disabling security protocols (Option A) can expose the website to cyber attacks and is not advisable. Shifting operations to a third-party platform (Option C) may not be feasible or desirable and could introduce additional security and control challenges. Focusing solely on marketing strategies (Option D) does not address the critical need to balance responsiveness with security during peak traffic periods.

In this scenario, the goal is to enhance security without disrupting email functionality. Option A, blocking all SMTP traffic, would prevent the mail server from functioning properly, disrupting email services. Option C, replacing SMTP with a more secure protocol, could enhance security but would require significant changes to the email infrastructure and may not be immediately feasible. Option D, enabling logging, is a good security practice but does not prevent exploitation of vulnerabilities. The most effective solution is Option B, restricting SMTP traffic to only allow connections from trusted external IP addresses. This approach reduces the attack surface by limiting potential attackers' access to the SMTP service while allowing legitimate email traffic.

Implementing role-based access control (RBAC) (Option B) is the most appropriate step to ensure that employees only have access to data necessary for their job roles, aligning with effective internal security compliance. Increasing the frequency of internal audits (Option A) is beneficial but does not address the immediate issue of excessive data access. Providing additional training (Option C) is important for awareness but does not directly restrict unnecessary access. Encrypting all patient data (Option D) enhances data security but does not solve the problem of excessive access rights. RBAC directly addresses the issue by aligning access rights with job requirements, thereby reducing the risk of unauthorized access or data breaches.

The most effective first action to mitigate an on-path attack, where data packets are being intercepted and modified, is to implement secure protocols like HTTPS (Option B). These protocols encrypt data in transit, making it difficult for attackers to read or alter the information. Changing user passwords (Option A) is important for overall security but does not address the issue of data interception. Installing an advanced IDS (Option C) can help detect suspicious activities but does not prevent the interception and modification of data. Physically securing the network infrastructure (Option D) is essential, but the attack might be occurring at any point along the data path, not necessarily within the physical premises of the company.

To leverage automation as a workforce multiplier more effectively, especially in the context of challenges in identifying and mitigating emerging threats, the IT department should focus on training the IT staff to analyze trends and develop proactive security strategies (option B). Automation frees up time by handling routine tasks, allowing IT staff to focus on higher-level functions such as trend analysis, threat hunting, and strategic planning. This approach maximizes the benefits of automation by using the saved time for activities that require human expertise and judgment. Options A, C, and D might be beneficial in other contexts but do not directly address the issue of effectively leveraging automation to enhance the capabilities of the existing workforce.

In the event of discovering a leaked database containing company login credentials through open-source intelligence (OSINT), the primary concern is to mitigate the risk of unauthorized access. The most effective initial action is to notify all employees whose credentials are potentially compromised to change their passwords immediately. This step helps prevent attackers from using the exposed credentials to gain access to the company's systems or data. It's a direct and proactive measure to safeguard against potential exploitation of the leaked information. Option B, conducting an internal investigation, is important but secondary to the immediate need to secure accounts. Option C, monitoring the dark web, can provide additional insights but does not address the immediate risk. Option D, contacting the authorities, is a relevant step in the case of a confirmed data breach, but the first priority should be to secure the potentially compromised accounts.

The DDoS attack on the online retailer during a significant sales event, which led to substantial financial loss but did not involve data breach or ransom demands, is indicative of a threat actor aiming to cause disruption and chaos (Option C). This type of attack is often motivated by the desire to disrupt operations and create chaos for its own sake, rather than for financial extortion (Option A), corporate sabotage (Option B), or as part of state-sponsored activities (Option D). The lack of a clear financial or strategic motive suggests the goal was to cause disruption during a critical business period.

In the context of a software company distributing updates, hashing plays a crucial role in ensuring the integrity of the software updates. Hashing involves generating a unique hash value (a fixed-size string of characters) from the software update's data. This hash value acts as a digital fingerprint of the update. When users download the update, they can generate a hash value from the downloaded file and compare it to the original hash value provided by the software company. If the hash values match, it confirms that the update has not been altered or tampered with during transmission. This process ensures that the software update remains intact and trustworthy, safeguarding against potential threats like malware insertion or data corruption.

The most effective immediate action to investigate the anomaly of out-of-cycle logging is to analyze the log entries (Option B). This involves reviewing the logs for any signs of unusual or unauthorized activities that could indicate a security breach or system malfunction. Implementing stricter access controls (Option A) is a good security practice but does not address the immediate need to understand the cause of the increased logging. Increasing the logging level (Option C) might provide more detailed information but can also generate an overwhelming amount of data and may not be necessary to identify the issue. Conducting a company-wide password reset (Option D) is disruptive and may not be relevant if the cause of the logging is unrelated to account security.

The primary improvement needed in the company's incident response plan is establishing a clear protocol for timely communication with affected parties (Option C). This ensures that customers are promptly informed about the breach and can take necessary actions to protect their information. While investing in detection systems (Option A) and focusing on encryption methods (Option D) are important for prevention and protection, they do not address the issue of communication during an incident. A public relations strategy (Option B) is important for managing the company's image but should be part of a broader communication protocol.

The most likely reason for the failure of the automated attestation process is that the system is not integrated with all the organization's resources (Option C). For an automated attestation system to be effective, it must have access to and control over all the systems and resources where user access rights are granted. If it is not fully integrated, some access rights may not be reviewed and revoked as needed. While manual review (Option A) and regular training (Option D) are important, they do not directly address the issue of incomplete system integration. Users bypassing the attestation process using VPNs (Option B) is unlikely, as attestation is about confirming access rights rather than controlling real-time access.

The key reason for implementing secure data erasure and factory reset procedures during the decommissioning of old workstations is to safeguard against the recovery of proprietary data. By thoroughly erasing all data and resetting the workstations, the organization ensures that sensitive or proprietary information cannot be retrieved by subsequent users, thereby protecting data confidentiality and security. While facilitating resale or donation (Option B) and reducing maintenance costs (Option D) may be secondary considerations, the primary focus is on preventing unauthorized access to and recovery of sensitive data. Ensuring compatibility with new IT infrastructure (Option A) is not a direct concern in the decommissioning process.

The most effective approach to ensure full legal compliance is to consult with legal experts in each country to align the corporation's policies with both GDPR and local data protection regulations (Option B). This ensures that the corporation's policies are tailored to meet the specific legal requirements in each jurisdiction, thereby avoiding the risk of non-compliance. While harmonizing policies with GDPR (Option A) is important, it does not address the nuances of local regulations. Creating a universal policy that ignores local variations (Option C) could lead to non-compliance in specific countries. Focusing on the strictest regulations (Option D) may not adequately address all local legal requirements.

In this scenario, the appropriate action to counter potential social engineering is for the receptionist to ask the caller for their employee ID and verify it with the IT department, as suggested in Option B. This step ensures that the caller's identity and request are legitimate before granting any access. It demonstrates vigilance and adherence to security protocols, crucial in preventing unauthorized access through social engineering tactics. Granting remote access without verification (Option A) is risky and could lead to a security breach. Directing the caller to send an official email request (Option C) is a safer approach but may still be part of a sophisticated social engineering attempt. Hanging up and ignoring the call (Option D) may seem like a safe choice but could potentially disregard a legitimate request, hence verification is a more balanced approach.

The primary security advantage of removing unnecessary software from company computers is to reduce the risk of malware infections by minimizing attack vectors. Unnecessary or unused software can be exploited as a potential entry point for malware and other cyber threats. By removing these applications, the IT department effectively reduces the number of vulnerabilities that could be targeted by attackers, thereby decreasing the likelihood of malware infections. This proactive measure enhances the overall security of the IT infrastructure. While freeing up storage space and enhancing performance (Option A), simplifying the user interface (Option C), and streamlining software updates (Option D) are beneficial, the key objective in this context is to improve security by reducing potential vulnerabilities.

Implementing multi-factor authentication (MFA) for user logins (Option B) is the most effective measure against brute force attacks on a web application. MFA adds an additional layer of security beyond just the password, making it significantly more difficult for attackers to gain unauthorized access, even if they manage to guess or crack the password. Requiring complex passwords (Option A) is important, but MFA provides a higher level of security. Conducting regular penetration testing (Option C) is a good practice to identify vulnerabilities but does not directly prevent brute force attacks. Monitoring and analyzing login attempts (Option D) can help detect attacks, but it does not prevent them like MFA does.

The scenario describes multiple failed login attempts from a remote IP address on an administrator account at an unusual time and without any scheduled maintenance. This pattern is indicative of a brute force attack, where an attacker is attempting to gain unauthorized access by trying different password combinations. The fact that the administrator account is not typically used for remote access further suggests a malicious intent. A misconfiguration in remote access settings (Option B) would not explain the multiple failed attempts. An expired password (Option C) could lead to failed logins but would more likely involve known IPs and less frequent attempts. The possibility of a legitimate user (Option D) is unlikely given the absence of scheduled maintenance and the use of an account not designated for remote access.

This scenario illustrates the value of upgrading legacy systems, particularly regarding their security aspects, within change management processes. The educational institution's decision to postpone upgrading the legacy student information system due to concerns about the learning curve and integration challenges ultimately led to a security breach. This breach, which compromised sensitive student data, demonstrates the risks associated with using outdated systems that lack modern security features. Change management processes must prioritize the security implications of continuing to use legacy systems. Upgrading or replacing these systems with more secure and modern solutions is essential to protect against cyber threats and ensure the confidentiality and integrity of sensitive information.

For an e-commerce company expanding its online services to a new subdomain, the primary security advantage of using an existing wildcard SSL/TLS certificate is that it extends SSL/TLS encryption to the new subdomain without the need for an additional certificate. A wildcard certificate is designed to secure the main domain and all its subdomains with a single certificate. This means that when the company adds a new subdomain to its online presence, the wildcard certificate automatically provides SSL/TLS encryption for this subdomain as well. This capability simplifies the process of securing new subdomains, ensuring that they are protected with encryption from the outset and maintaining a consistent level of security across the company's entire web domain.

This incident best illustrates a Misconfiguration vulnerability. Misconfiguration occurs when security settings, in this case, the configuration of a firewall, are not correctly implemented or maintained, leading to security weaknesses. The incorrectly configured firewall, with critical ports inadvertently left open to the internet, provided attackers with an opportunity to exploit these vulnerabilities and gain unauthorized access. Social Engineering (Option A) involves manipulating individuals to gain confidential information, Malware Infection (Option C) refers to the unauthorized installation of malicious software, and Physical Security Breach (Option D) involves unauthorized physical access, which are different from the issue of misconfiguration.

Data replication contributes to minimizing downtime for an online retail company's e-commerce platform by providing real-time or near-real-time copies of data across multiple servers or locations (A). This approach ensures that if one server or location experiences an issue, the replicated data on other servers or locations can be immediately accessed, allowing the e-commerce platform to continue operating with minimal disruption. Data replication focuses on data availability and redundancy rather than enhancing server processing speed (B), automatically updating software (C), or reducing physical space for servers (D). Therefore, the key advantage of data replication in this context is A) Providing real-time or near-real-time copies of data to maintain platform availability and minimize downtime.

For a healthcare organization requiring both high availability and security for its online services, configuring the load balancer to perform SSL offloading (Option C) is a significant consideration. SSL offloading involves handling the decryption of SSL/TLS-encrypted traffic at the load balancer, which reduces the processing load on the backend servers. This configuration enhances the performance and efficiency of the servers, allowing them to handle more user requests and improving overall availability. Additionally, it maintains security by ensuring encrypted communication. A round-robin algorithm (Option A) is a common method for distributing traffic but does not specifically address the security aspect. Configuring the load balancer as primary storage (Option B) is not its intended function, and filtering spam emails (Option D) is typically the role of email security systems, not load balancers.

Implementing rate limiting on the switch ports (C) is the most effective technique for protecting core switches from Denial of Service (DoS) attacks. Rate limiting controls the amount of traffic that can pass through a port, preventing the switch from being overwhelmed by excessive traffic typical in DoS attacks. Enabling QoS (A) is beneficial for managing network traffic but does not specifically protect against DoS attacks. Configuring SNMPv3 (B) enhances the security of network management but does not directly address DoS attack prevention. Regularly updating firmware (D) is crucial for overall security but is a general best practice rather than a specific measure against DoS attacks.

The unusual pattern of database queries, especially those involving large data extractions, strongly suggests a SQL Injection attack. This type of attack manipulates a web application's database interactions to execute unauthorized queries. Reviewing and adjusting the web application firewall (WAF) settings can help to identify and mitigate such attacks. Option B (DDoS attack) typically affects network resources rather than database interactions. Option C (Insider threat) and Option D (Misconfiguration) could be possible causes but are less likely given the specific pattern of database queries observed.

In the detection phase of incident response, it is crucial to accurately identify and understand the nature and scope of the incident. This involves gathering additional information about the suspicious activity to confirm whether it is a security incident and to assess its impact. Option B represents this critical step of further investigation to make informed decisions about how to proceed. While disconnecting affected systems (Option A) may be a subsequent action, it should not be done prematurely without sufficient understanding of the situation. Notifying legal departments (Option C) and law enforcement (Option D) are typically later steps once the incident is confirmed and more information is available.

When outsourcing network management to a third-party vendor, establishing a clear service level agreement (SLA) with defined security responsibilities (Option B) is crucial. An SLA should detail the roles and responsibilities of both the small business and the vendor, including specific security measures, response times, hardware and software maintenance protocols, and incident response procedures. This ensures that both parties have a clear understanding of their obligations and the standards that must be maintained. Delegating all security responsibilities to the vendor (Option A) is risky, as it's important for the business to retain some level of oversight and control. Choosing a vendor based solely on a recommendation (Option C) may overlook critical due diligence steps such as assessing the vendor's security capabilities. While cost savings (Option D) are a factor in vendor selection, focusing exclusively on this aspect can lead to compromises in security and service quality.

In the context of change management, particularly for critical systems like financial transaction processing, the emphasis is on ensuring security and compliance while minimizing risks. Even though the update has passed preliminary tests, the suggestion to perform additional risk analysis aligns with best practices in change management. This step is crucial to identify and mitigate any potential security vulnerabilities that might have been overlooked. It demonstrates a proactive approach to security, prioritizing thorough evaluation over expedited deployment. The approval process in change management must be rigorous, especially when dealing with critical updates that impact security and compliance.

Upon learning that a key supplier has been the target of a cyberattack, the manufacturing company's first action should be to conduct a thorough review of its own network security (Option B). This review is essential to identify any vulnerabilities that may have been exploited through the supply chain and to ensure that the company's network has not been compromised. It also helps in assessing the effectiveness of existing security controls and in determining if any immediate actions are needed to strengthen security. Finding an alternative supplier (Option A) or temporarily halting operations with the supplier (Option D) may be considered as longer-term strategies, but they do not address the immediate need to secure the company's own network. Requesting a detailed security report from the supplier (Option C) is a useful step to understand the nature of the breach and any potential implications, but it should not be the first action before ensuring the company's network is secure.

The scenario emphasizes the importance of data confidentiality and integrity in a financial firm's data center upgrade. Option B, servers with built-in hardware-based encryption capabilities, directly addresses these needs by providing a means to protect data at rest and in transit. Hardware-based encryption is a crucial security feature that ensures only authorized individuals can access the data, thereby maintaining its confidentiality and integrity. Option A, focusing solely on processing power and storage capacity, does not directly address the security concerns. Option C, prioritizing cost-effectiveness, may compromise on necessary security features. Option D, considering warranty period, is important for long-term maintenance but does not impact the immediate security of data.

Applying full disk encryption to the servers is the most effective measure for protecting sensitive data at rest. Full disk encryption ensures that all data stored on the servers, including customer personal identification numbers and credit card details, is encrypted and unreadable without the proper decryption key. This measure provides a high level of security by protecting the data from unauthorized access or theft, particularly in the event of a physical breach or server theft. While a robust firewall (A), strong password policies (B), and antivirus software (D) are important aspects of a comprehensive security strategy, they do not specifically address the protection of data at rest in the same way that full disk encryption does.

In this scenario, the challenge is to manage the high volume of alerts from the file integrity monitoring system, many of which are false positives caused by routine software updates. Option A, disabling FIM during software update periods, could create a window of vulnerability where actual malicious changes might go undetected. Option C, configuring FIM to alert only for file changes outside business hours, might miss malicious activities that occur during business hours. Option D, increasing the alert threshold, could reduce sensitivity to the point where important changes are not detected. The most effective solution is Option B, fine-tuning the FIM settings to exclude directories where routine software updates occur. This approach reduces false positives by not monitoring areas of the system that undergo expected changes, while still maintaining vigilant monitoring of critical system files and areas not typically affected by routine updates.
