Cryptography and Network Security
Qus:1
Describe the stream and block encryption with their advantages and
disadvantages.
Answer:
Block ciphers are more
powerful objects, with a more complicated interface ("encrypt or decrypt
an arbitrary block of data", instead of just "produce a
keystream" or "produce a keystream with this nonce").
Qus:2

Qus:4
List all the models of security and explain any two models for operating system
security.
Answer:
The
models of security:
·
Multilevel security
·
Lattice
model of access security:
·
Bell–La
Padula confidentiality model:
·
Biba
integrity model:
Multilevel
security:
Ideally, we want
to build a model to represent a range of sensitivities and to reflect the need
to separate subjects rigorously from objects to which they should not have
access. For instance, consider an election and the sensitivity of data involved
in the voting process. The names of the candidates are
Qus:5
Define and explain IP security. Explain its architecture.
Answer:
IP
security:
IPSec provides
connectionless, best-effort delivery of datagrams through a network by
protecting it from snooping or modification. IPSec protects IP datagrams by
defining a method of specifying the traffic to protect, how that traffic is to
be protected, and to whom the traffic is sent. IPSec can protect packets
between hosts, between network security gateways, or between hosts and
Qus:6
Describe guard and personal firewalls.
Answer:
Guard
and Personal firewalls:
Guard:
A guard is a
sophisticated firewall. Like a proxy firewall, it receives protocol data units,
interprets them, and passes through the same or different protocol data units
that achieve either the same result or a modified result. The guard decides
what services to perform on the user's behalf in
