Implementing Transport Layer Security (TLS) is essential for encrypting web access to sensitive information, such as employees' tax and personal data, accessible through a public-facing web portal. TLS is a cryptographic protocol that ensures secure communication over a computer network. It provides confidentiality, integrity, and authenticity of data during transmission by encrypting the data between the user's browser and the web server. This encryption protects sensitive information from eavesdroppers and man-in-the-middle attacks, making it crucial for safeguarding private data during online transactions.

While the other options contribute to security in different ways, they do not address the encryption of web access specifically. A Network Intrusion Detection System (NIDS) focuses on monitoring network traffic for suspicious activity but does not encrypt data. The Advanced Encryption Standard (AES) is a strong encryption algorithm that is often used for encrypting data at rest or for securing communications, but it is not a protocol for web communication like TLS. Lastly, Two-factor authentication (2FA) enhances access security by requiring two forms of verification, but it does not provide encryption for data transmitted over the network. Thus, utilizing TLS is the ideal solution for encrypting web access to sensitive employee information.
