What is the value of file hashes to network security investigations?
- They can serve as malware signatures.
- They ensure data availability.
- They offer confidentiality.
- They assure nonrepudiation.
Explanation: Data confidentiality, integrity, availability and nonrepudiation are all crucial components of data security. The use of encryption algorithms ensures data confidentiality by safeguarding information from being disclosed to unauthorized people, processes, or devices. Data Integrity uses hashes or a message digest to ensure data nonalteration. Data availability ensures timely and reliable access to data for authorized users, whereas nonrepudiation is the ability to prove that an operation or event has occurred and cannot be repudiated later on.
