In its kind the Cybersecurity Framework of the Department is the most comprehensive and efficient one. The Department of Homeland Security performing the following activities to secure the cyberspace efficiently:
 Checking and assessing organizations capacity of cyber-attacks defensive mechanisms and potentials.
 Evaluate organizations decision making and incident response strategies at the national level.
 Validate and confirm communication and information sharing methods. Create awareness about new cyber incidents and way of response, and recovery practices.
 Review the way of sharing sensitive and private information without compromising the national security interests.

5. Cybersecurity Framework
The Framework is a risk-based strategy for conducting Cybersecurity peril and is comprised of three components: The Framework Core, Implementation Tiers, and Profiles. All the above Framework segment strengthens the relationship between business drivers and cybersecurity activities.

 The Framework Core is a collection of cybersecurity activities, aspired results, and appropriate recommendations that are familiar with significant foundation areas.
 Framework Implementation Tiers present a meaning on how The Department observes cybersecurity risk and what kind of method or processes need to follow to control and handle that risk.
 The Framework Profile describes the consequences depend on the Department demands that already chosen and decided from the Framework segments and Sub-segments.

6. Threat Identification
The following Information security risks are identified by The US Department of Homeland Security that can compromise confidentiality, availability, and integrity of the system are:
 Administrative, Maintenance, Software and System Design and User Errors
 Denial of service, virus, spyware, trojan, worm attacks
 Unauthorized modification of data
 Electronic Warfare,
 Terrorist act such as Terrorist cyber-attack,
 Natural disasters such as Hurricane, Lightning, Tornado, Volcano.

7. Risk Management
The Department risk management includes the following processes:
 Assessing and evaluating all types of Risks
 Evacuating all kinds of Security Controlling Methods and procedures
 Cost and Benefit Analysis
 Recognize and understand Security Constraints
 Assessing security laws, policies, and regulations

8. Risk Assessment Approach
The Department risk assessment approach is used information security system analysis to find out security vulnerabilities and to determine lethal threats to the system. Also, the approach efficiently mitigates chances of risks by evaluating the existing countermeasures and by assessing providing cost effective security strategies. The Approach follows series steps to identify threats and to recommend the best security methods and practices.

9. System Vulnerabilities
The primary objective of system vulnerability is to determine the weakness of the Department networking system. The system assessing communications, environmental, personal securities and evaluating significant and specific hardware, to identify the vulnerabilities of information technologies in the department. Also, the approach evaluating security controlling systems to check whether they are properly implemented or not.

9.1 Vulnerability Assessment
After vulnerability system identified primary threats, the vulnerability assessment process will follow. The assessment will identify and evaluate existed vulnerabilities in the system and provide different security countermeasures to mitigate and control the risk probability in the network. The assessment also compares and contrast the previous vulnerability assessment methods with the new one to improve the current security strategy.

10. Controls Analysis
The principal objective of control analysis is to examine the existing or the planned controlling system to minimize the possibility of potential vulnerabilities and threats. The control analysis additionally considering to launch different controlling strategies that mitigate active threats and reduce the chances that can increase the probability of various risks. Also, the controlling analysis diminishing the weaknesses of the security control system.

10.1 Establishing Controls
The US Department of Homeland Security used IACS (Information Assurance Compliance System) to generate Requirements Traceability Matrix (RTM). The matrix is a checking list of controlling systems. The list assessing that controlling system is efficient, and which one are not or need update and improvement. The chick list is also referring the source, control name, method, and category of the controlling systems.

10.2 Control Methods
The department security controlling system use two types of methods, Technical, and Nontechnical.
The primary goal of Technical Controlling Methods is to preserve and protect the security of:
 Firmware, hardware, software,
 Encryption and intrusion detection system,
 Access control, identification and authentication mechanisms.

The Nontechnical control methods used to preserve and safeguard:
 Security procedures and policies,
 Operational plans,
 Personnel, physical, and environmental safeties.

11. Business Continuity Plan
Business Continuity Plan is critical to continue the regular service and activity at the time of service interruption such as natural disaster or security incidents. The Department of Homeland Security Business continuity plan will be distributed to the management team of the continuity plan, and the master plan is kept by the leader of the group. Additional one copy of the program is retained in the Emergency Operation Center (EOC) of the Department, and that help the team members to review the plan quickly ate the time of activation of the business continuity plan. The business continuity plan incorporated initial response and disaster response plans. The Development of a business continuity plan in the department includes four consecutive steps:
 Distinguish critical and sensitive business functions and resources to gather business impact study.
 Recognize documents and resources that support the business recovery process.
 Prepare the company continuity plan team and develop its plan to handle and control a business interruption.
 Give proper recovery strategies to the business continuity team and evaluate the plan recovery methods.

11.1 Incident response plan
The Department has an Incident Response team. The team is responsible for reporting any incident information on time as soon as it is collected to the US-CERT (United States Computer Emergency Readiness). For all governmental offices, the US-CERT serve as the significant information security incident reporting body. All Federal Government incident response teams need to use standard taxonomy.

11.2 Disaster Recovery Plan
The recovery plan is a strategy for data and information technology retrieval system. The recovery plan plays a decisive role to retreat necessary information technologies and equipment and that help to proceed the proper operation at the time of service interruptions. The recovered Information and technology (IT) include networks, servers, desktop and laptop computers and wireless devices. The recovery plan also plays a vital role in running critical software and applications at the time of service interruption by restoring regular business operations.

12. Policy
The US Department of Homeland Security has chosen the Security Planning principles established in NIST SP 800-53. The following outline the Security plans and standards that constitute The Department of Homeland Security policy:
 All The Homeland Security Business Systems need to adhere to a formal, documented security planning policy. The official security policy includes or needs to address the purpose of the system, the scope of the policy, the roles of the policy, responsibilities and the management strategy.

POA&Ms create a framework to minimize weakness, and implement suggested security measures, recognize sources and determine related expenses. The proposed safety measures in this security plan need to be incorporated in the Test_2015-01-15-1052 POA&M and excited due to The US Department Homeland Security Plans of action and milestones guide requirement to mitigate the standard and the level of jeopardy that affiliated with the system.
