A regulatory requirement is a mandate imposed by a government or an authority that must be followed by an organization or an individual. In a banking environment, audits are often required by regulators to ensure compliance with laws, standards, and policies related to security, privacy, and financial reporting. Audits help to identify and correct any gaps or weaknesses in the security posture and the internal controls of the organization.

Zero-day vulnerabilities are unknown flaws in software, making them harder to patch, especially when using open-source libraries without dedicated support teams.

=================

A high-availability network is a network that is designed to minimize downtime and ensure continuous operation even in the event of a failure or disruption. A high-availability network must consider the following factors12:

Ease of recovery: This refers to the ability of the network to restore normal functionality quickly and efficiently after a failure or disruption. Ease of recovery can be achieved by implementing backup and restore procedures, redundancy and failover mechanisms, fault tolerance and resilience, and disaster recovery plans.

Attack surface: This refers to the amount of exposure and vulnerability of the network to potential threats and attacks. Attack surface can be reduced by implementing security controls such as firewalls, encryption, authentication, access control, segmentation, and hardening.

The other options are not directly related to high-availability network design:

Ability to patch: This refers to the process of updating and fixing software components to address security issues, bugs, or performance improvements. Ability to patch is important for maintaining the security and functionality of the network, but it is not a specific factor for high-availability network design.

Physical isolation: This refers to the separation of network components or devices from other networks or physical environments. Physical isolation can enhance the security and performance of the network, but it can also reduce the availability and accessibility of the network resources.

Responsiveness: This refers to the speed and quality of the network’s performance and service delivery. Responsiveness can be measured by metrics such as latency, throughput, jitter, and packet loss. Responsiveness is important for ensuring customer satisfaction and user experience, but it is not a specific factor for high-availability network design.

Extensible authentication: This refers to the ability of the network to support multiple and flexible authentication methods and protocols. Extensible authentication can improve the security and convenience of the network, but it is not a specific factor for high-availability network design.

Within an organization's Software Development Life Cycle (SDLC), an Information Security Policy is a vital component. It outlines the rules and procedures for ensuring that the organization’s IT assets and data are protected throughout the development process. Ensuring secure coding practices, access controls, and regular security testing is fundamental in preventing vulnerabilities in applications.

Other options like service-level agreements and branch protection requirements are less likely to be integral to SDLC processes. Penetration testing methodology, while useful, is generally considered outside the scope of the SDLC​​.

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.

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.

Unidentified removable devices, such as USB drives, are a common threat vector for insider threat actors attempting data exfiltration. Insiders can easily use these devices to transfer sensitive data out of the organization undetected, making it one of the most commonly utilized methods for data theft.

Default network device credentials are a security vulnerability but not typically used for data exfiltration.

Spear phishing emails are used for external attacks, not insider data exfiltration.

Impersonation through typosquatting is typically used by external actors for phishing or fraud​​.

The most important security concern when using legacy systems is the lack of vendor support. Without support from the vendor, systems may not receive critical security patches and updates, leaving them vulnerable to exploitation. This lack of support can result in increased risk of security breaches, as vulnerabilities discovered in the software may never be addressed.

A disaster recovery plan (DRP) is a set of policies and procedures that aim to restore the normal operations of an organization in the event of a system failure, natural disaster, or other emergency. A DRP typically includes the following elements:

A risk assessment that identifies the potential threats and impacts to the organization’s critical assets and processes.

A business impact analysis that prioritizes the recovery of the most essential functions and data.

A recovery strategy that defines the roles and responsibilities of the recovery team, the resources and tools needed, and the steps to follow to restore the system.

A testing and maintenance plan that ensures the DRP is updated and validated regularly. A DRP is required for an organization to properly manage its restore process in the event of system failure, as it provides a clear and structured framework for recovering from a disaster and minimizing the downtime and data loss. References = CompTIA Security+ Study Guide (SY0-701), Chapter 7: Resilience and Recovery, page 325.

Detailed Explanation:Standard operating procedures (SOPs) outline the steps to be followed to maintain a secure baseline, such as testing and deploying patches while minimizing risk to the system. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Patch Management and Baseline Compliance"​​.

Baseline configuration is the process of standardizing the configuration settings for a system or network. In this scenario, the organization needs to standardize the operating system configurations before deploying them across the network. Establishing a baseline configuration ensures that all systems adhere to the organization's security policies and operational requirements.

An insider threat is a security risk that originates from within the organization, such as an employee, contractor, or business partner, who has authorized access to the organization’s data and systems. An insider threat can be malicious, such as stealing, leaking, or sabotaging sensitive data, or unintentional, such as falling victim to phishing or social engineering. An insider threat can cause significant damage to the organization’s reputation, finances, operations, and legal compliance. The user’s activity of logging in remotely after hours and copying large amounts of data to a personal device is an example of a malicious insider threat, as it violates the organization’s security policies and compromises the confidentiality and integrity of the data. References = Insider Threats – CompTIA Security+ SY0-701: 3.2, video at 0:00; CompTIA Security+ SY0-701 Certification Study Guide, page 133.

Comprehensive and Detailed In-Depth Explanation:

Aload balancerdistributes incoming traffic evenly across multiple servers to prevent any single server from becoming overloaded. This ensureshigh availability, scalability, and optimal performanceof the company's website.

Server multiprocessing (A)refers to the use of multiple processors within a single server but does not distribute traffic across multiple servers.

A warm site (B)is a disaster recovery strategy, not a method for balancing real-time traffic.

A proxy server (D)acts as an intermediary between users and web services but does not distribute server load.

Using aload balancerallows forefficient traffic management and prevents server overload.

SQL injection is a type of attack that exploits a database misconfiguration or a flaw in the application code that interacts with the database. An attacker can inject malicious SQL statements into the user input fields or the URL parameters that are sent to the database server. These statements can then execute unauthorized commands, such as reading, modifying, deleting, or creating data, or even taking over the database server. SQL injection can compromise the confidentiality, integrity, and availability of the data and the system. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 215 1
