Which process focuses on keeping communication secure during its transmission?

• A. Transmission security
• B. Storage security
• C. Access control
• D. Physical security

Answer: (A)

The process that focuses on keeping communication secure during its transmission is transmission security. This involves various techniques and protocols aimed at protecting data from unauthorized interception, alteration, or access while it is being transmitted over communication channels.

Transmission security encompasses methods such as encryption, which encodes the information in a way that only authorized parties can decode and understand it. It also includes measures like secure communication protocols that guard against eavesdropping and tampering during data transfer. By ensuring that communication is secure in transit, organizations can protect sensitive information from potential threats that may arise while the data is moving between points.

In contrast, storage security pertains to protecting data that is stored on devices or systems, access control focuses on restricting who can view or manipulate data, and physical security involves safeguarding hardware and facilities from physical threats. Each of these areas plays an important role in overall information security, but they do not specifically address the preservation of confidentiality, integrity, and availability of data during its transmission.
