1If you have a file which is encrypted using EFS in Windows, if you mount the Windows volume using Kali and open the file, what will happen?
- AThe file will open but the contents are scrambled and unreadable
- BYour access will be denied with an error message stating "access is denied"
- CAllowed since Linux ignores Windows file permissions
- DAllowed if you login to Linux with the same user credentials you used to encrypt the file
2Which of the following might be used to accomplish public key exchange in a establishing an https:// connection
- AMD5
- BDES
- CRSA
- DDSA
3In asymmetric encryption, if encrypt data with my public key...
- AThe data is encrypted with a one-way have and cannot be decrypted
- BA digital signature is created for decryption
- COnly my public key can decrypt the data
- DOnly my private key can decrypt the data
4The identities of hosts involved in a secured TLS transaction can be verified by a
- Aa pre-shared key
- Ba certificate authority
- Cthe authentication token
- Dthe GPO
5Encryption primarily comes in two forms; symmetric and asymmetric. What purpose is symmetric encryption most often used for?
- AAuthentication data
- BTo move large quantities of data securely
- CTo establish an initial secure channel
- DTo independently calculate and share the value of a session key
6Which of the following technologies use a streaming cipher?
- AWEP
- B3DES
- CRSA
- DAES
7Your certificate could contain the following except;
- AYour Public Key
- BYour Private key
- CYour certificate authorities digital signature
- Dyour digital signature
8Which of the following uses symmetric encryption?
- ARC4
- BRSA
- CDiffie Helman
- DPrivate key/public key encryption
9IPSEC is implemented at what layer of the OSI network model?
- ALayer 1
- BLayer 2
- CLayer 3
- DLayer 4
- ELayer 5
- FLayer 6
- GLayer 7
10Which of the following is considered a more secure way of transferring a large file?
- ATLS
- BSSL
- Csmime
- DRC4
11Diffie-Hellman describes...
- AA secure symmetric encryption system for transmitting encrypted data
- BA way to mathematically calculate a shared session key with another machine in an untrusted network
- CUses private and public keys to establish a secure connection in an untrusted network
- DIs a hashing algorithm
12Where is the symmetric key for decryption stored for a file which has been encrypted using EFS?
- Ain the header of the document, encrypted with the users public key
- Bin the header of the document encrypted with the users private key
- CIn the profile of the user
- DOn the certificate authority for the domain
13If your browser connects up to a web server on port 443, it is because it is trying to initiate
- AAn SSL connection
- BA TLS connection
- CAn IPSec connection
- DA VPN connection
14Kerberos is considered secure because
- AThe user must authenticate their password on the Domain Controller, where they are stored securely
- BAll data that is sent in a Kerberos transaction is encrypted
- CSince the sent password is hashed, it cannot be reversed
- DKerberos uses tickets, and never sends user credentials on the network
15Which of the following might be used to authenticate a user in a VPN connection
- AMS-CHAP
- BAES
- CRSA
- DMD5
16Hashing is important for doing which of the following in a secure transaction?
- ANon-Repudiation
- BConfidentiality
- CIntegrity Checking
- DEncryption
17While doing symmetric encryption using a block cipher, to ensure the security of the data, you should...
- ASelect an encryption cipher which uses a large block size
- BSelect an encryption cipher which uses a large key size
- CBlock size and key size are equally important, so they should both be large
- DSelect a streaming cipher algorithm to increase the encryption
18One of the weaknesses of asymmetric encryption is that it
- AHas trouble with swapping and keeping keys secure
- BIs computationally difficult making it relatively slow
- CThe small key size makes it "crackable"
- DThe session key must be kept secret forever
19When you set up a Public Key Infrastructure on your domain, you can be sure of the identity of other parties because...
- ABecause all of the certificates have been issued by your trusted Certificate Authority
- BBecause both parties will use the same pre-shared key
- CKerberos will authenticate the other party for you
- DThis is defined in the IPSEC policies
