2ENTERPRISE SECURITY ASSIGNMENT
Introduction
The security is a major concern for the current organization as the implication would
allow the secure information management. It has been assisting for integrating the work for
aligning with the consideration for information transfer. The alignment of the following report
would be helpful for analysis of the virus of Stuxnet and its impact on the organizational
structure. The consideration is also helpful for enduring the utilization of the quantitative risk
analysis for identifying the risk factors for the nuclear program. The calculation of the exposure
factor, single loss expectancy, annualized rate of occurrence, and annualized loss expectancy has
been considered for forming the evaluation of the program. The report would also provide a
basic information of the TOGAF and the procurement method used in the movie “Contact”.
Explanation of Stuxnet
Stuxnet can be explained as malicious computer worm having the extremely
sophisticated structure and it exploits multiple windows for forming the analysis of the improved
functional development. The malware was built jointly by the American-Israeli weapon for
targeting the influence of the effective and smart management process. The activities would be
implied with the consideration of the activities aligning the influence of the effective
management processing. The malware targets the Program Logic Controller (PLC) hindering the
process of automation of the electrochemical process. The attack source of Stuxnet was
initialized with the initial vector for the sequencing of the infection. The OS has been deigned in
a way that the external removable storages and devices can be supported. Another good feature
for the industrial absorption and USB environmental ports. The controlling of the prevention

method has been implied with the factors for developing the alignment of the endpoint access in
the system.
Stuxnet has been designed for the harming and attacking specific areas of the system and
hence it can be considered for the evaluation of the factors for development. The Stuxnet cane be
considered for the harming the various networks and systems. The system can exploit and enter
into those systems that are unreachable for the Siemens also. The malware would infect the
system and with the help of it spreading ability would spread to the rest of the system
components. The malware has been specifically designed for the subverted industrial system as it
can reduplicate itself harming one components from other in multiple forms. The offline systems
can be reached with the help of the hardware components within the industrial computers.
Stuxnet mainly attacks the project files and devices while incorporating the different
levels of propagation in the system with single motive of infecting the project files. The PLC
devices has been continuously being harmed for allowing the informal development of the
factors for taking care of the factors for the development of the improved management process.
The worm has been targeting Windows system for listing the probable management. The
formation of the PLC windows based system influence would be effective for the listing of the
probable influence of the machine level language. The identification of the PLC model would be
effective for the development of the factors for considering the involvement of the successive
development.
The antiviruses works on system software and protects the system from being infiltrated
from software point of view. The access in the system using the programs of the software can be
protected and detected using the antiviruses. The involvement of the successful development
management for protecting from the influence of the malware from the alignment of the factorial

development model. The Stuxnet would work on the hardware and form the major influence on
the compilation of the work influence on the PLC. The influence of the PLC model has been
largely adopted for the consideration of the PLC model identification. The malware results in
forming the major impact on the machine level instruction and the variation on the PLC device.
Qualitative Risk analysis
The qualitative risk analysis has been shown below,
Total Cost of the Nuclear Programme (Asset Value) $1,000.00
In case of a successful Air Strike, expected loss: $500.00
Successful air strike happens once in (years) 20
By installing S300 Missiles, the Exposure factor is reduced by a factor of 10
By installing S300 Missiles, the occurrence of successful air strike would reduce
by
50%
The S300 yearly cost is (ACS, Annual Cost of Safeguard) $15.00
The Chinese HQ18 yearly cost is (ACS, Annual Cost of Safeguard) $7.50

Should the programme
implement the S300 or
HQ18? Why?
HQ18 should be implied
HQ18 has the same effectiveness as the S300 and the cost of
implementing the HQ18 is less than that of S300. Hence, for more
value effectiveness, Hq18 should be implied for decreasing the cost
for the management of loss.
TOGAF
Q. Which one of the following best describes the TOGAF standard?
A. A framework and method for architecture development
Q. What does ADM stand for in TOGAF
A. Architecture development model
Q. What are the likely requirements in OUR scenario?
A. The TOGAF structure for the provided scenario is given below,

Movie Contact
No, we would not use the “have two, for twice the price” as the budget for the second option
would consume 15 million dollars (which is twice of first option 7.5 million dollars)
If there is more than 75% probability of the occurrence of the attack, the option of “have two, for
twice the price” can be used for ensuring the successful completion of the project
In general circumstances, the option is not valid as it would exhaust twice the cost of the system
developed for implying the management of the successful completion of the project.

The option (S300) is hot site as it would allow the continuation of the protection of the nuclear
program even after the failure of the HQ18. The facility would allow the significant management
of the successful completion of the project.
Conclusion
It can be concluded from the assignment that the implication would be helpful for taking
care of the factors for aligning the management. The alignment of the following report had been
helpful for analysis of the virus of Stuxnet and its impact on the organizational structure. The
nuclear sector had been implied with the consideration for the factors and management of the
improved factors. The successful implication management for the listing the analysis for the
formation of the factors. The analysis had been implied with the formation development for
project intuition.
