When an attacker is attacking our encryption, they are MOSTLY targeting which leg of the CIA triad?

Options are :

  • Authentication.

We have chosen to use multiple types of data destruction on our sensitive data. Why would we do that?

Options are :

  • Because it is easier than just a single type of data destruction.
  • To ensure there is no data remanence. (Correct)
  • To ensure data is still accessible after the destruction.
  • To make sure we have the old drives available.

Answer : To ensure there is no data remanence.

Explanation It is common to do multiple types of data destruction on sensitive data (both degaussing and disk crushing/shredding). While it may not be necessary, it is a lot cheaper than a potential $1,000,000 fine or loss of proprietary technology or state secrets.

What would be a COMMON attack on our data at rest?

Options are :

  • Cryptanalysis. (Correct)
  • Shoulder surfing.
  • Eavesdropping.
  • All of these.

Answer : Cryptanalysis.

Explanation Data at Rest (Stored Data): This is data on Disks, Tapes, CDs/DVDs, USB Sticks. We use disk encryption (full/partial), USB encryption, tape encryption (avoid CDs/DVDs). Encryption can be Hardware or Software Encryption.

An attacker has stolen one of our backup tapes. What could prevent the data on the tape from being accessible?

Options are :

  • Proper data handling.
  • Proper data storage.
  • Proper data retention.
  • Proper data encryption. (Correct)

Answer : Proper data encryption.

Explanation Proper encryption can prevent data compromise even if the physical tape is lost. This obviously requires that the encryption is strong enough.

Options are :

  • On our routers.
  • In use on a workstation.
  • Traversing our network.
  • On tapes. (Correct)
  • On a hard disk. (Correct)
  • On a CD. (Correct)

Options are :

  • Degauss.
  • Overwrite.
  • Shred.
  • All of these. (Correct)

Answer : All of these.

Explanation With regular spinning disk hard drives, degauss, overwrite and shred are all good options. Often done with more than one of them just to be sure.

We want to ensure there is no data remanence when we dispose of our old hard disks. When we overwrite a hard disk, what does the overwrite program do?

Options are :

  • Writes random letters over used sections of the disk.
  • Writes 0's over all the sectors with active data on it.
  • Writes 0's over all the sectors. (Correct)
  • Writes random numbers over all the sectors.

Answer : Writes 0's over all the sectors.

Explanation Overwriting is done by writing 0’s or random characters over the data. As far as we know there is no tool available that can recover even single pass overwriting (not possible on damaged media).

In our organization we do not own a degasser or disk crusher. What should we do with our old hard disks when we need to dispose of them?

Options are :

  • Since we have no means of destroying them, we have done our due care and we can recycle them with the rest of the electronic waste.
  • We can pay another company to do it. (Correct)
  • We can overwrite all the functional disks and the rest we can ignore since they are damaged anyways.
  • We can throw them in a lake or the ocean.

Answer : We can pay another company to do it.

Explanation If we do not have the means for proper data destruction, we can pay another company to do so. They obviously have to be licensed to do so and adhere to all our security policies.

A historical type of encryption that was based on a set of disks with random letters; the sender and receiver would agree on the disk order. What is it called?

Options are :

  • Caesar cipher.
  • Spartan Scytale.
  • Vigenère cipher.
  • Bazeries. (Correct)

Answer : Bazeries.

Explanation The Jefferson Disk (Bazeries Cylinder) - is a cipher system using a set of wheels or disks, each with the 26 letters of the alphabet arranged around the edge. Jefferson (US president) invented it, and Bazeries improved it. The order of the letters is different for each disk and is usually scrambled in some random way. Each disk is marked with a unique number. A hole in the center of the disks allows them to be stacked on an axle. The disks are removable and can be mounted on the axle in any order desired. The order of the disks is the cipher key, and both sender and receiver must arrange the disks in the same predefined order. Jefferson's device had 36 disks.

After the Second World War the US designed and built the SIGABA. How many rotors did it use?

Options are :

  • 3
  • 4
  • 10

Options are :

  • AH.
  • ESP.
  • SA.
  • DR. (Correct)

Answer : DR.

Explanation IPSEC (Internet Protocol Security): Set of protocols that provide a cryptographic layer to IP traffic (IPv4 and IPv6). It uses AH (Authentication Header) to provide authentication and integrity for each packet. ESP (Encapsulation Security Payload) which provides confidentiality and SA (Security Association) which is a simplex one-way communication (Like a walkie talkie).Can be used to negotiate ESP or AH parameters.

172.32.0.0/24 is which type of IPv4 addresses?

Options are :

  • Loopback.
  • Link-local.
  • Private.
  • Public. (Correct)

Answer : Public.

Explanation This is a public address and it is internet routable, not to be confused by the private IPv4 range of 172.16.0.0 – 172.31.255.255, we can use them on our internal network, they are not routable on the internet.
