Part 1, cipher rounds (3 at 3 points each), part 2, multiple choice, 1 point each.
\nSuppose we have the plaintext byte: lower case s = 01110011 in ascii binary:
\nL1 L2 L3 L4 R1 R2 R3 R4
\nPlainText 0 1 1 1 0 0 1 1<\/p>\n
1. Show the next full substitution and transposition round using the information above if the next subkey is 1110:
\nL1 L2 L3 L4 R1 R2 R3 R4
\nPlainText 0 1 1 1 0 0 1 1
\nSubkey
\nApply Round Function to Rbits
\nRound Function Result
\nXOR with Lbits
\nSwap halves<\/p>\n
2. Starting from the last round, do the next full substitution and transposition round if the next subkey is 0001:
\nL1 L2 L3 L4 R1 R2 R3 R4
\nPlainText
\nSubkey
\nApply Round Function to Rbits
\nRound Function Result
\nXOR with Lbits
\nSwap halves<\/p>\n
3. Now, ignoring the previous round, say we are on the 11th round and we have the following plaintext byte in binary:
\nL1 L2 L3 L4 R1 R2 R3 R4
\nPlainText 0 1 0 1 0 1 1 1<\/p>\n
And if you have the following subkey 1010, complete the round:<\/p>\n
L1 L2 L3 L4 R1 R2 R3 R4
\nPlainText
\nSubkey
\nApply Round Function to Rbits
\nRound Function Result
\nXOR with Lbits
\nSwap halves<\/p>\n
4. In Windows, what subsystem is responsible for brokering access to objects:
\n___ Object Manager (OM) ___ Security Accounts Manager (SAM)
\n___ Active Directory (AD) ___ Mandatory Access Control Manager (MACM)<\/p>\n
5. X.509 certificates are based on the standard issued by:
\n___ The United States Government ___ International Standards Organization
\n___ Microsoft ___ International Telecommunications Union<\/p>\n
6. A \u201cgood\u201d security policy should cover all of the following EXCEPT:
\n___ Correcting Physical Damage ___ Recovering from Human Errors
\n___ Disaster Recovery ___ How to Retaliate<\/p>\n
7. At what layer begins end-to-end security?
\n___ Session ___ Network
\n___ Transport ___ Application<\/p>\n
8. ______________________ are implemented by the network resource manager making a decision about allowing or denying a request to access an object by a user and the security level of the object. In this approach, users are given a security clearance and data are classified with the classification stored in the security labels of the resource.
\n___ A discretionary access control (DAC) ___ Permitted access control (PAL)
\n___ Mandatory access control (MAC) ___ Configured access level (CAL)<\/p>\n
9. A pessimistic security stance:
\n___ Only permits those actions specifically allowed ___ Is the same thing as a blacklist
\n___ Permits actions unless they are explicitly denied ___ Is usually the default setting in router firewalls<\/p>\n
