ESSAY QUESTIONS Instructions: Answer all questions in a single document. Then submit to the
appropriate assignment folder. Each response to a single essay question should be about a half-page in
length (about 150 words).
1. Cryptographic algorithms provide the underlying tools to most security protocols used in today’s
infrastructures. The choice of which type of algorithm depends on the goal that you are trying to
accomplish, such as encryption or data integrity. These algorithms fall into two main categories:
symmetric key and asymmetric key cryptography. In this essay, please discuss the strengths and
weaknesses of symmetric key cryptography and give an example of where this type of cryptography is
used. Then discuss the strengths and weaknesses of asymmetric key cryptography and give an example
of where this type of cryptography is used.
2. Cryptography has been used in one form or another for over 4000 years and attacks on cryptography
have been occurring since its inception. The type of people attempting to break the code could be
malicious in their intent or could just be trying to identify weaknesses in the security so that
improvements can be made. In your essay response, define cryptanalysis and describe some of the
common cryptanalytic techniques used in attacks.
3. Many people overlook the importance of physical security when addressing security concerns of the
organization. Complex cryptography methods, stringent access control lists, and vigilant intrusion
detection/prevention software will be rendered useless if an attacker gains physical access to your data
center. Site and facility security planning is equally important to the technical controls that you
implement when minimizing the access a criminal will have to your assets. In your essay response, define
CPTED and describe how following the CPTED discipline can provide a more aesthetic alternative to
classic target hardening approaches. Make sure that the three CPTED strategies are covered in your
response.
4.What benefit do digital signatures provide and what are their characteristics? In your own words, what
does non-repudiation mean?
5.Identify the malicious threat sources to physical security and their corresponding countermeasures.
