To meet the requirements for authentication using trusted third parties and session maintenance, SAML (Security Assertion Markup Language) and JWT (JSON Web Token) are the best options. SAML is widely used for single sign-on (SSO) and federated authentication, allowing users to authenticate with an external identity provider (trusted third party). JWT is commonly used for maintaining authenticated sessions across web applications and is well-suited for long-term session management, like the six-month duration mentioned. Together, these solutions meet the requirements for standards-based authentication and long-lasting sessions. CASP+ discusses the role of SAML in federated identity management and JWT in token-based authentication.

To automate the process of handling phishing attempts and updating blocklists, the best solution is to implement SOAR (Security Orchestration, Automation, and Response). SOAR platforms allow organizations to define automated workflows for responding to security incidents, such as phishing attacks. In this case, SOAR can automate the identification of phishing attempts and update blocklists in real-time, improving response time and consistency. MSSP (Managed Security Service Provider) and MDR (Managed Detection and Response) are outsourced services that do not directly address the need for automation, and containerization and virtualization are unrelated to incident handling. CASP+ emphasizes the value of automation in streamlining security operations and improving response times to threats.

PCI DSS (Payment Card Industry Data Security Standard) is the most appropriate governance framework when collecting and processing credit card data, including international user data. PCI DSS establishes security standards for organizations that handle payment card transactions and ensures theprotection of cardholder data globally. The other options, such as ISO 27001 and NIST 800-53, provide general security frameworks, but PCI DSS is specifically designed for payment card security, which is critical when handling credit card information. CASP+ emphasizes the role of PCI DSS in ensuring the secure handling of payment data.

The security analyst should remove the cipher TLS_DHE_DSS_WITH_RC4_128_SHA to support the business requirements, as it is considered weak and vulnerable to on-path attacks. RC4 is an outdated stream cipher that has been deprecated by major browsers and protocols due to its flaws and weaknesses. The other ciphers are more secure and compliant with secure-by-design principles and PCI DSS.

IMAPS (Internet Message Access Protocol Secure) is a protocol that allows users to access and manipulate email messages on a remote mail server over a secure connection. IMAPS uses SSL/TLS encryption to protect the communication between the client and the server. IMAPS uses port 993 by default. To ensure IMAPS functions properly on the corporate user network, the security engineer should create an IMAPS firewall rule on the UTM (Unified Threat Management) device that allows traffic from VLAN 10 (Corporate Users) to VLAN 20 (Email Server) over port 993. The existing firewall rules do not allow this traffic, as they only allow HTTP (port 80), HTTPS (port 443), and SMTP (port 25).

This solution would address the three issues as follows:

Serving static content via distributed CDNs would reduce the latency for international users by delivering images from the nearest edge location to the user’s request.

Creating a read replica of the central database and pulling reports from there would offload the read-intensive workload from the primary database and avoid affecting the inventory data for order placement.

Auto-scaling API servers based on performance would dynamically adjust the number of servers to match the demand and balance the load across them at peak times.

A multicloud provider solution is the best option for proceeding with the digital transformation while ensuring SLA (service level agreement) requirements in the event of a CSP (cloud service provider) incident. A multicloud provider solution is a strategy that involves using multiple CSPs for different cloud services or applications, such as infrastructure, platform, or software as a service. A multicloud provider solution can provide resiliency, redundancy, and availability for cloud services or applications, as it can distribute the workload and risk across different CSPs and avoid single points of failure or vendor lock-in. An on-premises solution as a backup is not a good option for proceeding with the digital transformation, as it could involve high costs, complexity, or maintenance for maintaining both cloud and on-premises resources, as well as affect the scalability or flexibility of cloud services or applications. A load balancer with a round-robin configuration is not a good option for proceeding with the digital transformation, as it could introduce latency or performance issues for cloud services or applications, as well as not provide sufficient resiliency or redundancy in case of a CSP incident. An active-active solution within the same tenant is not a good option for proceeding with the digital transformation, as it could still be affected by a CSP incident that impacts the entire tenant or region, as well as increase the costs or complexity of managing multiple instances of cloud services or applications.

Utilizing a source code escrow will reduce the operational risk to the company if the third party stops supporting the application, as it will provide access to the latest version of the source code to continue development. A source code escrow is an agreement between a software developer and a client that involves depositing the source code of a software product with a third-party escrow agent. The escrow agent can release the source code to the client under certain conditions specified in the agreement, such as bankruptcy, termination, or breach of contract by thedeveloper. The company will not be able to force the third-party developer to continue support, manage their development process, or pay them to hire a new development team by utilizing a source code escrow.

Mobile application management (MAM) is a solution that allows the organization to control and secure the approved collaboration applications and the data within them on personal devices. MAM can prevent unstructured data from being exfiltrated by restricting the ability to move,copy, or share data between applications. Multi-factor authentication (MFA) is a solution that requires the user to provide more than one piece of evidence to prove their identity when accessing corporate data. MFA can prevent data from being exfiltrated as a result of compromised credentials by adding an extra layer of security. Digital rights management (DRM) is a solution that protects the intellectual property rights of digital content by enforcing policies and permissions on how the content can be used, accessed, or distributed. DRM can prevent sensitive information in emails from being exfiltrated by encrypting the content and limiting the actions that can be performed on it, such as forwarding, printing, or copying.

DLP (data loss prevention) is a solution that can meet the following requirements: identify sensitive data in the provider’s network, maintain compliance with company and regulatory guidelines, detect and respond to insider threats, privileged user threats, and compromised accounts, and enforce data-centric security, such as encryption, tokenization, and access control. DLP can monitor, classify, and protect data in motion, at rest, or in use, and prevent unauthorized disclosure or exfiltration. WAF (web application firewall) is a solution that can protect web applications from common attacks, such as SQL injection or cross-site scripting, but it does not address the requirements listed. CASB (cloud access security broker) is a solution that can enforce policies and controls for accessing cloud services and applications, but it does not address the requirements listed. SWG (secure web gateway) is a solution that can monitor and filter web traffic to prevent malicious or unauthorized access, but it does not address the requirements listed.

Restricting HTTP methods can mitigate the risk of network-based attacks against an online store by limiting the types of HTTP requests that the server will accept, thus reducing the attack surface. This is a common method to prevent web-based attacks such as Cross-Site Scripting (XSS) and SQL Injection.

The process ID 87 can be the starting point for an investigation of a possible buffer overflow attack, as it shows a high percentage of CPU utilization (99.7%) and a suspicious command name (graphic.linux_randomization.prg). A buffer overflow attack is a type of attack that exploits a vulnerability in an application or system that allows an attacker to write data beyond the allocated buffer size, potentially overwriting memory segments and executing malicious code. A high CPU utilization could indicate that the process is performing intensive or abnormal operations, such as a buffer overflow attack. A suspicious command name could indicate that the process is trying to disguise itself or evade detection, such as by mimicking a legitimate program or using random characters. The other process IDs do not show signs of a buffer overflow attack, as they have low CPU utilization and normal command names.

Microsegmentation enabled by software-defined networking is an architectural design that can meet the requirements of allowing users to access only predefined services, having unique allow lists defined for each user, and constructing one-to-one subject/object access paths dynamically. Microsegmentation is a technique that divides a network into smaller segments or zones based on granular criteria, such as applications, services, users, or devices. Microsegmentation can provide fine-grained access controland isolation for network resources, preventing unauthorized or lateral movements within the network. Software-defined networking is a technology that decouples the control plane from the data plane in network devices, allowing centralized and programmable management of network functions and policies. Software-defined networking can enable microsegmentation by dynamically creating and enforcing network segments or zones based on predefined rules or policies. Peer-to-peer secure communications enabled by mobile applications is not an architectural design that can meet the requirements of allowing users to access onlypredefined services, having unique allow lists defined for each user, and constructing one-to-one subject/object access paths dynamically, as peer-to-peer secure communications is a technique that allows direct and encrypted communication between two or more parties without relying on a central server or intermediary. Proxied application data connections enabled by API gateways is not an architectural design that can meet the requirements of allowing users to access only predefined services, having unique allow lists defined for each user, and constructing one-to-one subject/object access paths dynamically, as proxied application data connections is a technique that allows indirect and filtered communication between applications or services through an intermediary device or service that can modify or monitor the traffic. VLANs (virtual local area networks) enabled by network infrastructure devices is not an architectural design that can meet the requirements of allowing users to access only predefined services, having unique allow lists defined for each user, and constructing one-to-one subject/object access paths dynamically, as VLANs are logical segments of a physical network that can group devices or users based on common criteria, such as function, department, or location.

Modeling user behavior and monitoring for deviations from normal and continuously monitoring code commits to repositories and generating summary logs are actions that will enable the data feeds needed to detect unauthorized insertions into application development environments and authorized insiders making unauthorized changes to environment configurations. Modeling user behavior and monitoring for deviations from normal is a technique that uses baselines, analytics, machine learning, or other methods to establish normal patterns of user activity and identify anomalies or outliers that could indicate malicious or suspicious behavior. Modeling user behavior and monitoring for deviations from normal can help detect unauthorized insertions into application development environments, as it can alert on unusual or unauthorized access attempts, commands, actions, or transactions by users. Continuously monitoring code commits to repositories and generating summary logs is a technique that uses tools, scripts, automation, or other methods to track and record changes made to code repositories by developers, testers, reviewers, or other parties involved in the software development process. Continuously monitoring code commits to repositories and generating summary logs can help detect authorized insiders making unauthorized changes to environment configurations, as it can audit and verify the source, time, reason, and impact of code changes made by authorized users. Performing static code analysis of committed code and generate summary reports is not an action that will enable the data feeds needed to detect unauthorized insertions into application development environments and authorized insiders making unauthorized changes to environment configurations, but an action that will enable the data feeds needed to detect vulnerabilities, errors, bugs, or quality issues in committed code. Implementing an XML gateway and monitor for policy violations is not an action that will enable the data feeds needed to detect unauthorized insertions into application development environments and authorized insiders makingunauthorized changes to environment configurations, but an action that will enable the data feeds needed to protect XML-based web services from threats or attacks by validating XML messages against predefined policies. Monitoring dependency management tools and report on susceptible third-party libraries is not an action that will enable the data feeds needed to detect unauthorized insertions into application development environments and authorized insiders making unauthorized changes to environment configurations, but an action that will enable the data feeds needed to identify outdated or vulnerable third-party libraries used in software development projects. Installing an IDS (intrusion detection system) on the development subnet and passively monitor for vulnerable services is not an action that will enable the data feeds needed to detect unauthorized insertions into application development environments and authorized insiders making unauthorized changes
