Part 1 – IT Security Interview Questions (Basic)
This first part covers basic Interview Questions and Answers.
Q1. Provide some examples and details regarding the encryption of email transmission.
One of the popular software for encrypting email transmission is PGP (Pretty Good Privacy). This software is very popular for encrypting email data smartly to avoid data leakage uncertainty. It is not only useful to encrypt mail bodies, rather than it can be very popular for signing, encrypting, or decryption features for physical files, normal text, full directories, attached data, and even whole data partitions as well. As all the big companies are very concerned about hiding or encrypting their specific communication, PGP is one of the common choices for them to use in any communication. The main utility of PGP is using a secret private key which is only known to the tool, and one shareable public key which is available for both sender and receiver. So the receiver can easily identify or verify the sender’s secure identity to confirm the sender person’s security and verify the proper integrity of the content shared by the sender. The receiver can effortlessly understand whether someone in the network root has tampered with the mail or not.
A process of encryption & Decryption of PGP (Pretty Good Privacy):
- Data – Generate Random Key – Encrypt data using this random key – Encrypt random key by receiver public key (X1) – encrypt random key by sender public key (Y1) – Send encrypted data to the receiver.
- Encrypted Data – Decrypt X1 by receiver private key – Decrypt encrypted data by decrypting the result of X1 (the random key of earlier encryption) – display to the receiver.
Q2. What will be the secure access process in case of remote device access from your system?
There are many tools available for helping to connect with the other remote desktop from their system. Those tools are fully secured if we use a licensed version.
