Encryption alone ensures that transmitted data cannot be altered while in transit.

### Why this is right The statement is false because the material identifies both confidentiality and integrity threats when data travels over an unencrypted channel. Protection must address the possibility of interception and alteration, not just concealment. ### The concept Confidentiality in transit means preventing unauthorized parties from reading information. Integrity in transit means protecting information from undetected change. Encryption makes data unreadable without the appropriate key, but the course material describes TLS as protecting data in transit and also notes that unencrypted data may be altered. Do not assume that the word encryption, by itself, describes every protection a communication needs. ### The other options - **True**: this would be tempting because encryption hides readable content, but hiding content and detecting alteration are distinct security goals. ### Watch out The trap is treating confidentiality and integrity as the same property. A channel can need protection against both disclosure and modification. ### Terms - **TLS**: Transport Layer Security. A protocol used to protect data transmitted between systems. ### Remember For data in transit, assess both who can read it and whether it can be changed.
