Final answer:
Hashing and tools like Tripwire are used to ensure the integrity of data, which is one of the three key objectives of cybersecurity along with confidentiality and availability. Therefore correct option is B. Integrity
Step-by-step explanation:
The three key objectives of cybersecurity are often referred to as the CIA triad: Confidentiality, Integrity, and Availability. When it comes to techniques like hashing and the use of tools like Tripwire, these are primarily used to ensure the integrity of data.
Hashing is used to create a unique digital fingerprint of data, which can be checked to ensure that data has not been altered without authorization. Similarly, tools like Tripwire can detect and alert when changes are made to files or systems, thereby protecting the integrity of the systems they monitor.
The key objective of cybersecurity that is often ensured by using techniques like hashing and the use of tools like Tripwire is Integrity.
Integrity ensures that data remains intact, accurate, and trustworthy throughout its lifecycle. Techniques like hashing and the use of tools like Tripwire can help protect against unauthorized modifications or alterations to data by detecting any changes made to it.
Therefore correct option is B. Integrity
