introduction
• This chapter describes how enterprises can use
iterative assessments and prioritization to select,
plan ,resources and execute progressive
improvement to its cyber security posture
• Cyber security utilizes all management tools that
will be described in this chapter:
1. A frame work for managing a cyber security
program
2. A quantitative method for assessing the
program and identifying strengths and
weaknesses.
3. Ongoing operation and cycles of improvements

Enterprise cybersecurity program management:
• Cyber security management program are tied with risk mgt , control ,mgt ,
deficiency tracking , process improvement and measurement processes into
a single overarching programmatic cycle.
•The above figures of the enterprise cyber security program management
process involves an ongoing cycle of assessing threats and risks , making
progressive improvements to mitigate them and collecting metrics from security
options.

Cybersecurity program
step 1:assess assets , threats and Risks:
• All assets of enterprise , threats , and risks and its IT systems are assessed and
conclude the potentiality of missions attacker and are to breach
confidentiality ,compromise integrity or disrupt availability .
• When the scope of security is well defined that simplify the defensive process
by ensuring that measures are focus on needs the security scope , rather than
trying to protect everything from every possible threat simultaneously.
• This step’s output is an understanding of the enterprise assets to be protected
and the threats against those assets.
• Assets ? Might include all data and information, how attackers may target them.
• And to be economical for achieving the desired protection.

Step 2:Identify security scopes
• To group of assets , treats and Risk management in an enterprise in to security scopes for protection.
• CS capabilities should be played into security scopes ,many scopes may use the same security scopes , right
level of capabilities and right person to the right place.
• Additionally, security scopes are useful in identifying regulated data and
systems, and ensuring regulations are adhered to in a practical and economical fashion.
• there are two challenges that occur when using scope boundaries to
compartmentalize security.
– The first challenge is the enterprise must keep track of which policies, rules, and(solution :a limited number of scopes )
controls apply to which scope, potentially increasing complexity.
– The second challenge has to do with systems that cross scope boundaries, such as data interconnects
and systems administration consoles. (solution :interconnections do not become security vulnerabilities ). This is to do
not use administrative accounts for surfing internet and emails to open the permissions for attacker.
• Step 3, Assess Risk ,mitigation , capabilities by functional
area and security operations:
• With understanding of the assets , threats and Risks With in the security scope and next is assessing of
security scope. ,assess is done in 11 functional area ,
• Risk mitigation enterprise should use attack sequence to evaluate its ability to disrupt, defect ,delay and
defeat attacks against its assets. And assess each attack scenario and gather the result to gather .security
operations evaluate 17 security operational processes and the enterprises assesses its ability to perform
these processes to operate its cyber security systems. Enterprise scores these area then aggregated and
compared for evaluation and further analysis in security scope
• In security scope is adequately and inadequately protected (inadequately means specific activities can be
implemented to reach a stated improvement goal or target assessment score.

Step 4:Identify Target Security Levels
• With an idea of the assets, threats, risks, and effective security in each
scope, the next programmatic goal is to use risk assessment
methodology to identify the target security levels and understand if the
scope’s current security is adequate, inadequate, or even excessive.
• Various parts of the business require different preventive, detective,
forensic, and audit controls.
• Security scopes help prioritize limited cybersecurity
, deliver the greatest enterprise benefits.
• Security scopes also simplify the cybersecurity process by reducing the
attack surface of vulnerable systems and increasing cybersecurity’s
ability to succeed through that simplicity.
• this step involves identifying threats, risks, and a target
security level
• The identified security level represents the business tolerance for
potential compromise within the scope
• Security level is used to balance of different threats with business desire
for flexibility and unobtrusive security that does not imped the business
agility. Means different part requires different security protection.
• And security infrastructure requires greatest security protection.to
protect enterprise

Step 5:Identify Deficient Areas
• When security scope , actual security in the scope , and
target security levels are identified the next step is to identify
which areas are deficient and requires improvement
compared to the targets deficient identifying will produce
the bellow results:
1. Target security levels may be too high or too low
– In this situation, when the enterprise considers what additional security
capabilities might be necessary, When a different security posture is
required, the target security level can be adjusted either up or down, and the
evaluation can be reconsidered.
2. during the assessment, some functional areas are likely to stand out as
being considerably weaker than other areas. Prioritize weak area for
improvement , weaker area will provide gaps for exploitation of attacker.
3. Deficient functional areas are addressed the next improvement phase
includes bringing all areas up to target level of security , This phase
often involves a comprehensive effort to improve risk mitigations,
security capabilities , and security operations.

Step 6: Prioritize Remediation and Improvements
• Thus the security posture in enterprise is defined and also the requirement for each scope the next step is to
prioritize remediation and improvement efforts prioritize done by the following factors:
1. Bringing deficient functional areas up to target levels of security
2. Improvements that rely on other improvements as prerequisites
3. Availability and skill levels of available staff and contractors
4. Costs of improvements
The goal is to address deficient enterprise cybersecurity functional areas then work on bringing all functional
areas up to the target cybersecurity level in a balanced manner.
Improvements should be grouped into the following categories:
-Immediate(‫باال‬ ‫اولویت‬) -This Year((‫ها‬ ‫نیاز‬ ‫سازی‬ ‫مشخص‬ ‫با‬- Next Year(‫گرفتن‬ ‫بودیجه‬ ‫برای‬ ‫اداره‬ ‫تصویب‬ ‫و‬ ‫تایئ‬ ‫تکمیل‬ ‫و‬ ‫ها‬ ‫نیاز‬ ‫پیش‬ ‫سازی‬ ‫براورده‬ ‫با‬)–
Future(‫پروژه‬ ‫نیازهای‬ ‫و‬ ‫بودیجه‬ ‫اخذ‬ ‫پرسونل‬ ‫تکمیل‬ ‫با‬ ‫اولویت‬ ‫کمترین‬.)
‫ها‬ ‫اولویت‬ ‫ها‬ ‫اولویت‬ ‫سازی‬ ‫گروپ‬ ‫زیاد‬ ‫های‬ ‫اولویت‬ ‫برای‬ ‫و‬ ‫اند‬ ‫شده‬ ‫تقسیم‬ ‫فرعی‬ ‫های‬ ‫گروپ‬ ‫به‬ ‫ها‬ ‫اولویت‬ ‫به‬ ‫نظر‬ ‫انکشاف‬ ‫فوق‬ ‫های‬ ‫کتگوری‬ ‫در‬‫س‬ ‫ی‬‫ایب‬‫ر‬
‫گردد‬ ‫اجرا‬ ‫و‬ ‫تعین‬ ‫و‬ ‫منابع‬ ‫میتواند‬ ‫کار‬ ‫به‬ ‫و‬ ‫میسازد‬ ‫برابر‬ ‫سازمان‬ ‫مالی‬ ‫چرخه‬ ‫با‬ ‫را‬ ‫سکیوریتی‬.
Step 7:Resource and Execute Improvements:
Once improvements are prioritized, the enterprise can begin resourcing and executing them
resourcing are conducted in parallel against each category grouping of improvements:
For :
 Immediate (‫مینماید‬ ‫نظارت‬ ‫کار‬ ‫از‬ ‫و‬ ‫اغاز‬ ‫را‬ ‫کار‬ ‫سایبرسکیورتی‬ ‫رهبری‬)
 This Yea (‫میگردد‬ ‫اغاز‬ ‫سال‬ ‫همان‬ ‫در‬ ‫انکشاف‬ ‫و‬ ‫میسازد‬ ‫اماده‬ ‫را‬ ‫ها‬ ‫نیاز‬ ‫پیش‬ ‫و‬ ‫مینماید‬ ‫کار‬ ‫بندی‬ ‫اولویت‬ ‫و‬ ‫منابع‬ ‫سازماندهی‬ ‫برای‬ ‫رهبری‬)
 Next and Future ‫و‬ ‫نموده‬ ‫مالحظه‬ ‫اینده‬ ‫یال‬ ‫کار‬ ‫برای‬ ‫را‬ ‫بودیجه‬ ‫و‬ ، ‫مینماید‬ ‫گزاری‬ ‫پالن‬ ‫کار‬ ‫اغاز‬ ‫برای‬ ‫رهبری‬
Step 8: collect Operational Metrics:
As the enterprise executes its improvements and operates its security program the next program Is to collect metrics
from cybersecurity operations, the metrics include all functional areas , measure signs of security incidents or
indicators of attacker activities indicating the presence of anticipated threats. And shows threats are coming from
where and what can be the result if the threats are not before they can succeed for example:
For example, tracking and trending threats could show that the million scans are an increase from only
ten thousand from the previous month. Security takes on a whole new urgency if enterprise leadership has a mental
picture of attackers who are just waiting to pounce at the slightest mistake or vulnerability.

Step 9: Return to Step 1
• After collecting metrics, the cybersecurity program management
process returns to the assessment phase
and the cycle repeats This assess ➤ prioritize ➤ execute ➤ operate cycle
should go through a complete iteration multiple times each year.
• During each cycle, the enterprise updates its threat assessment, takes
stock of completed security improvements, identifies new security
improvements to implement, and lines up future security improvements for
execution when resources become available.
• Cycle iterates in different categories immediate , this year , next year until
they are executed
• The framework also provides the ability to report on both
immediate activities and the big picture strategy at any time
• Strategy helps to balance effectively cybersecurity with business
needs in cost effective manner.

Assessing security threats:
• Then the enterprise has assessed its assets ,threats and
Risks(step 1) and defined security scopes to contain those
risks (step 2) security posture and status in each scope the
next level may be over all security posture.
• In each scope considers to protect : confidentiality,
integrity, or availability
• enterprise needs to consider the appropriate balance of
preventive, detective, forensic, and audit controls to deliver
that protection

level of assessing the security status, per security scope:
Cyber security program step 3:assess Risk mitigations , capabilities and security
operations:
• 3A :Assessing cyber security Risk mitigations: What is the effectiveness of
risk mitigations within the security scope? What are the abilities of the risk
mitigations to disrupt the attack sequence of the anticipated attack?
• 3B: assessing cyber security capabilities by functional area: using Object
Measurement methodology to calculate enterprise cybersecurity program
assessment scores for each functional area.
• 3C: Assessing Security operations: considering the utilization and
effectiveness of the17 security operational processes and the 14 supporting
information systems. Objective Measurement.
• Step 4: Identify Target Security Levels:
• to identify the target cybersecurity levels for the scope , based on the risk
assessment process , that represents the target cybersecurity level for the
scope .
So, the target cybersecurity security level for the scope can be represented
as a single value that applies to the risk mitigations, functional areas, and
security operations.
The figures bellow shows the 11 functionality area:

The enterprise can depict the side-by-side results of its enterprise cybersecurity program
assessment of the risk mitigations, the 11 functional areas, and security operations, along
with the target cybersecurity level for the security scope.

Step 5: Identify Deficient Areas
12/26/2017 13
Once the scoring is complete and the results plotted
or otherwise displayed, the areas of the cybersecurity
program that are most deficient should be apparent.
1. Risk Mitigations (40%)
2. Functional Area: Systems Administration (40%)
3. Functional Area: Identity, Authentication, and Access Management (40%)
4. Functional Area: Incident Response (40%)
5. Functional Area: Asset Management (40%)
6. Security Operations (40%)
. These improvements should address the greatest known weaknesses in the overall
cybersecurity across the enterprise. Remember, a tenet of the enterprise cybersecurity
architecture in this section is that risk mitigations, functional areas, and security operations
are all of approximately equal importance in delivering overall enterprise cybersecurity.

Step 6: Prioritize Remediation and Improvements
• to prioritize the remediation and improvement efforts.
• These improvements should bring the following cybersecurity areas up to a
consistent score of approximately 60%: (1) risk mitigations, (2) systems
administration, (3) identity, authentication, and access management, (4) incident
response, (5) asset management and supply chain, and(6) security operations.
• Phase 1:
• • Functional Area: Data Protection and Cryptography
• Functional Area: High Availability, Disaster Recovery, and Physical Protection
• Functional Area: Policy, Audit, E-Discovery, and Training
• These phase 2 :
improvements might be accomplished by the following:
• Improving risk mitigations by addressing projected attack sequences
• Improving functional areas by adding security capabilities or improving their
utilization
•Improving security operations by implementing operational processes.

Considering Types of Improvements
• Risk mitigations disrupting, detecting, delaying, and defeating known threats and
their attack sequences.
• Security capabilities : the overall security capabilities will address unknown
threats, unanticipated attacks, defender mistakes, and attackers who use new technologies or
innovative approaches.
• Security operations : effective security operations is required to make them work
in repelling attacks on an ongoing basis.
• Considering Threat Scenarios
• What asset would be endangered (for example, credit card numbers that could
be stolen)
• Where the asset resides and when
• Who has access to the asset
• When and how an attacker might access the asset (for example, via the operating
system, database, application, or user account levels)
• Attack sequences for attackers to obtain access
• Audit controls to find the attacker’s access point, if the scenario occurred
• Forensic controls to log the access, if the assess occurred
• Detective controls to alert the enterprise when such access occurred
• Preventive controls to block such access from occurring
When the above are collected by third party should be evaluated for finding threat vectors.
This type of red-team exercise is useful to identify faulty enterprise cyber defender assumptions
and gaps in cyber defense thinking that might undermine the overall security posture.
12/26/2017 15

Prioritizing Improvement Projects
• Tasks have to be prioritized based on value and cost,
sequenced based on dependencies, and ultimately resourced
from limited available resources.
• Internal and external constraints.
• Projects are grouped in to the following :
• They directly thwart anticipated attacks or address known risks to improve risk mitigations
• They deliver capabilities that improve cybersecurity functional areas
• They strengthen cybersecurity operational processes .
leadership should consider the following questions related to
what it will take to successfully complete the project:
•

Tracking Cybersecurity Project Results:
As a quantitative method, these program assessment scores are well suited for
tracking results over time and aggregating results for functional areas and scopes into
combined scores that can then also be tracked and reported over time.
