Migrating to newer, supported applications where possible is the best approach to addressing security issues in legacy web applications. Legacy web applications are web applications that are outdated, unsupported, or incompatible with the current technologies and standards. Legacy web applications may have various security issues, such as:

• Vulnerabilities and bugs that are not fixed or patched by the developers or vendors
• Weak or obsolete encryption and authentication mechanisms that are easily broken or bypassed by attackers
• Lack of compliance with the security policies and regulations that are applicable to the web applications
• Incompatibility or interoperability issues with the newer web browsers, operating systems, or platforms that are used by the users or clients

Migrating to newer, supported applications where possible is the best approach to addressing security issues in legacy web applications, because it can provide several benefits, such as:

• Enhancing the security and performance of the web applications by using the latest technologies and standards that are more secure and efficient
• Reducing the risk and impact of the web application attacks by eliminating or minimizing the vulnerabilities and bugs that are present in the legacy web applications
• Increasing the compliance and alignment of the web applications with the security policies and regulations that are applicable to the web applications
• Improving the compatibility and interoperability of the web applications with the newer web browsers, operating systems, or platforms that are used by the users or clients

The other options are not the best approaches to addressing security issues in legacy web applications, but rather approaches that can mitigate or remediate the security issues, but not eliminate or prevent them. Debugging the security issues is an approach that can mitigate the security issues in legacy web applications, but not the best approach, because it involves identifying and fixing the errors or defects in the code or logic of the web applications, which may be difficult or impossible to do for the legacy web applications that are outdated or unsupported. Conducting a security assessment is an approach that can remediate the security issues in legacy web applications, but not the best approach, because it involves evaluating and testing the security effectiveness and compliance of the web applications, using various techniques and tools, such as audits, reviews, scans, or penetration tests, and identifying and reporting any security weaknesses or gaps, which may not be sufficient or feasible to do for the legacy web applications that are incompatible or obsolete. Protecting the legacy application with a web application firewall is an approach that can mitigate the security issues in legacy web applications, but not the best approach, because it involves deploying and configuring a web application firewall, which is a security device or software that monitors and filters the web traffic between the web applications and the users or clients, and blocks or allows the web requests or responses based on the predefined rules or policies, which may not be effective or efficient to do for the legacy web applications that have weak or outdated encryption or authentication mechanisms.

A responsibility of a data steward is to ensure that data decisions and impacts are communicated to the organization. A data steward is a role or a function that is responsible for managing and maintaining the quality and the usability of the data within a specific data domain or a business area, such as finance, marketing, or human resources. A data steward can provide some benefits for data governance, which is the process of establishing and enforcing the policies and standards for the collection, use, storage, and protection of data, such as enhancing the accuracy and the reliability of the data, preventing or detecting errors or inconsistencies, and supporting the audit and the compliance activities. A data steward can perform various tasks or duties, such as:

• Defining and documenting the data elements, attributes, definitions, and rules within the data domain or the business area, and ensuring that they are consistent and aligned with the data governance policies and standards.
• Monitoring and measuring the data quality and the data performance within the data domain or the business area, and identifying and resolving any data issues or problems, such as missing, inaccurate, or duplicate data.
• Coordinating and collaborating with the data owners, the data custodians, the data users, and the data governance team, and ensuring that the data decisions and impacts are communicated and understood by the organization, such as the data requirements, the data changes, or the data risks.

Ensuring that data decisions and impacts are communicated to the organization is a responsibility of a data steward, as it can help to ensure the transparency and the accountability of the data governance process, as well as to facilitate the coordination and the cooperation of the data governance stakeholders, such as the data owners, the data custodians, the data users, and the data governance team. Ensuring alignment of the data governance effort to the organization, conducting data governance interviews with the organization, and documenting data governance requirements are not responsibilities of a data steward, although they may be related or possible tasks or duties. Ensuring alignment of the data governance effort to the organization is a responsibility of the data governance team, which is a group of experts or advisors who are responsible for defining and implementing the data governance policies and standards, as well as for overseeing and evaluating the data governance process and performance. Conducting data governance interviews with the organization is a task or a technique that can be used by the data governance team, the data steward, or the data auditor, to collect and analyze the information and the feedback about the data governance process and performance, from the data governance stakeholders, such as the data owners, the data custodians, the data users, or the data consumers. Documenting data governance requirements is a task or a technique that can be used by the data governance team, the data owner, or the data user, to specify and describe the needs and the expectations of the data governance process and performance, such as the data quality, the data security, or the data compliance.

Transport Layer Security (TLS) provides peer identity authentication as one of its capabilities for a remote access server. TLS is a cryptographic protocol that provides secure communication over a network. It operates at the transport layer of the OSI model, between the application layer and the network layer. TLS uses asymmetric encryption to establish a secure session key between the client and the server, and then uses symmetric encryption to encrypt the data exchanged during the session. TLS also uses digital certificates to verify the identity of the client and the server, and to prevent impersonation or spoofing attacks. This process is known as peer identity authentication, and it ensures that the client and the server are communicating with the intended parties and not with an attacker. TLS also provides other capabilities for a remote access server, such as data integrity, confidentiality, and forward secrecy. References: Enable TLS 1.2 on servers - Configuration Manager; How to Secure Remote Desktop Connection with TLS 1.2. - Microsoft Q&A; Enable remote access from intranet with TLS/SSL certificate (Advanced …
