IT Security Risk Assessment

You are employed with Government Security Consultants, a subsidiary of Largo Corporation. As a
member of IT security consultant team, one of your responsibilities is to ensure the security of assets as
well as provide a secure environment for customers, partners and employees. You and the team play a
key role in defining, implementing and maintaining the IT security strategy in organizations.
A government agency called the Bureau of Research and Intelligence (BRI) is tasked with gathering and
analyzing information to support U.S. diplomats.
In a series of New York Times articles, BRI was exposed as being the victim of several security breaches.
As a follow up, the United States Government Accountability Office (GAO) conducted a comprehensive
review of the agency’s information security controls and identified numerous issues.
The head of the agency has contracted your company to conduct an IT security risk assessment on its
operations. This risk assessment was determined to be necessary to address security gaps in the
agency’s critical operational areas and to determine actions to close those gaps. It is also meant to
ensure that the agency invests time and money in the right areas and does not waste resources. After
conducting the assessment, you are to develop a final report that summarizes the findings and provides
a set of recommendations. You are to convince the agency to implement your recommendations.
This learning activity focuses on IT security which is an overarching concern that involves practically all
facets of an organization’s activities. You will learn about the key steps of preparing for and conducting
a security risk assessment and how to present the findings to leaders and convince them into taking
appropriate action.
Understanding security capabilities is basic to the core knowledge, skills, and abilities that IT personnel
are expected to possess. Information security is a significant concern among every organization and it
may spell success or failure of its mission. Effective IT professionals are expected to be uptodate
on
trends in IT security, current threats and vulnerabilities, stateoftheart
security safeguards, and
security policies and procedures. IT professionals must be able to communicate effectively (oral and
written) to executive level management in a nonjargon,
executive level manner that convincingly
justifies the need to invest in IT security improvements. This learning demonstration is designed to
strengthen these essential knowledge, skills, and abilities needed by IT professionals.

  1. Steps to Completion
    Your instructor will form the teams. Each member is expected to contribute to the team agreement
    which documents the members’ contact information and sets goals and expectations for the team.
    1) Review the Setting and Situation
    The primary mission of the Bureau of Research and Intelligence (BRI) is to provide multiplesource
    intelligence to American diplomats. It must ensure that intelligence activities are consistent with U.S.
    foreign policy and kept totally confidential. BRI has intelligence analysts who understand U.S. foreign
    policy concerns as well as the type of information needed by diplomats.
    The agency is in a dynamic environment in which events affecting foreign policy occur every day. Also,
    technology is rapidly changing and therefore new types of security opportunities and threats are
    emerging which may impact the agency.
    Due to Congressional budget restrictions, BRI is forced to be selective in the type of security measures
    that it will implement. Prioritization of proposed security programs and controls based on a sound risk
    assessment procedure is necessary for this environment.
    The following incidents involving BRI’s systems occurred and reported in the New York Times and other
    media outlets:
    • BRI’s network had been compromised by nationstatesponsored
    attackers and that attacks are
    still continuing. It is believed that the attackers accessed the intelligence data used to support
    U.S. diplomats.
    • The chief of the bureau used his personal email
    system for both official business purposes and
    for his own individual use.
    • A software defect in BRI’s human resource system – a web application – improperly allowed
    users to view the personal information of all BRI employees including social security numbers,
    birthdates, addresses, and bank account numbers (for direct deposit of their paychecks). After
    the breach, evidence was accidently destroyed so there was no determination of the cause of
    the incident or of its attackers.
    • A teleworker brought home a laptop containing classified intelligence information. It was stolen
    during a burglary and never recovered.
    • A disgruntled employee of a contractor for BRI disclosed classified documents through the
    media. He provided the media with, among other things, confidential correspondence between
    U.S. diplomats and the President that were very revealing.
    32
    • Malware had infected all of the computers in several foreign embassies causing public
    embarrassment, security risks for personnel and financial losses to individuals, businesses and
    government agencies including foreign entities.
    These reports prompted the U.S. Government Accountability Office to conduct a comprehensive review
    of BRI’s information security posture. Using standards and guidance provided by the National Institute
    of Standards and Technology and other parties, they had the following findings:
    Identification and Authentication Controls
    • Controls over the length of passwords for certain network infrastructure devices were set to less
    than eight characters.
    • User account passwords had no expiration dates.
    • Passwords are the sole means for authentication.
    Authorization Controls
    • BRI allowed users to have excessive privileges to the intelligence databases. Specifically, BRI did
    not appropriately limit the ability of users to enter commands using the user interface. As a
    result, users could access or change the intelligence data.
    • BRI did not appropriately configure Oracle databases running on a server that supported
    multiple applications. The agency configured multiple databases operating on a server to run
    under one account. As a result, any administrator with access to the account would have access
    to all of these databases; potentially exceeding his/her job duties.
    • At least twenty user accounts were active on an application’s database, although they had been
    requested for removal in BRI’s access request and approval system.
    Data Security
    • BRI does not use any type of data encryption for dataatrest
    but protects dataintransit
    using
    VPN.
    • A division data manager can independently control all key aspects of the processing of
    confidential data collected through intelligence activities.
    • One employee was able to derive classified information by “aggregating” unclassified databases.
    • Hackers infiltrated transactional data located in a single repository and went ahead and
    corrupted it.
    33
    System Security
    • Wireless systems use the Wired Equivalent Privacy (WEP) standard for ensuring secure
    transmission of data.
    • The agency permitted the “Bring Your Own Device” (BYOD) concept and therefore users can
    utilize their personal mobile devices to connect to the agency network freely.
    • In the event of a network failure due to hacking, the data center manager has his recovery plan
    but has not shared it with anyone in or out of the center. He was not aware of any requirement
    to report incidents outside of the agency.
    • There has never been any testing of the security controls in the agency.
    • Processes for the servers have not been documented, but in the minds of the system managers.
    • Patching of key databases and system components has not been a priority. Patching systems
    have either been late or not performed at all. Managers explained that it takes time and effort
    to test patches on its applications.
    • Scanning devices connected to the network for possible security vulnerabilities are done only
    when the devices are returned to inventory for future use.
    • System developers involved with financial systems are allowed to develop code and access
    production code.
    Physical Security
    • An unauthorized personnel was observed “tailgating” or closely following an official employee
    while entering a secure data center.
    • The monthly review process at a data center failed to identify a BI employee who had separated
    from BRI and did not result in the removal of her access privileges. She was still able to access
    restricted areas for at least three months after her separation.
    End User Security
    • Users even in restricted areas are allowed to use social media such as Facebook. The argument
    used is that is part of the public outreach efforts of the agency.
    • Users receive a 5minute
    briefing on security as part of their orientation session that occurs
    typically on their first day of work. There is no other mention of security during the course of
    employment.
    • Users are allowed to use public clouds such as Dropbox, Box, and Google Drive to store their
    data.
    34
    • BRI has not performed continual background investigations on employees who operate its
    intelligence applications (one investigation is conducted upon initial employment).
    • There is no policy regarding the handling of classified information.
    An internal audit report indicated that the organization needed several security programs including a
    security awareness and training program, a privacy protection program and a business
    continuity/disaster recovery programs. These programs will need special attention.
    2) Examine Background Resources
    This learning demonstration focuses on the National Institute of Standards and Technology’s (NIST)
    “Guide for Conducting Risk Assessments”
    (http://csrc.nist.gov/publications/nistpubs/80030rev1/
    sp800_30_r1.pdf). See Pg. 23 to view the
    description of the risk management process.
    Throughout this learning activity, feel free to use other references such as:
    Other NIST publications (http://csrc.nist.gov/publications/PubsSPs.html),
    SANS Reading Room (http://www.sans.org/readingroom/),
    USCERT
    (https://www.uscert.
    gov/securitypublications),
    CSO Magazine (http://www.csoonline.com/),
    Information Security Magazine (http://www.infosecuritymagazine.
    com/whitepapers/),
    Homeland Security News Wire (http://www.homelandsecuritynewswire.com/topics/cybersecurity)
    Other useful references on security risk management include:
    https://books.google.com/books?id=cW1ytnWjObYC&printsec=frontcover&source=gbs_ge_summary_r
    &cad=0#v=onepage&q&f=false
    https://books.google.com/books?id=FJFCrP8vVZcC&printsec=frontcover&source=gbs_ge_summary_r&c
    ad=0#v=onepage&q&f=false
    3) Prepare the Risk Assessment Plan
    Using the NIST report as your guide, address the following items:
    • Purpose of the assessment,
    • Scope of the assessment,
    • Assumptions and constraints, and
    • Selected risk model and analytical approach to be used.
    Document your above analysis in the “Interim Risk Assessment Planning Report.” (An interim report will
    be consolidated to a final deliverable in a later step.)
    35
    All interim reports should be at least 500 words long and include at least five references for each report.
    These reports will eventually be presented to management for their review.
    4) Conduct the Assessment
    Again, use the NIST report to address the following:
    1) Identify threat sources and events
    2) Identify vulnerabilities and predisposing conditions
    3) Determine likelihood of occurrence
    4) Determine magnitude of impact
    5) Determine risk
    You are free to make assumptions but be sure to state them in your findings.
    In determining risk, include the assessment tables reflect BRI’s risk levels. Refer to Appendix I. on risk
    determination in Special Publication 80030.
    Document your analysis from this step in the “Interim Risk Assessment Findings Report.” Be sure to
    include the final risk evaluations in this report.
    5) Identify Needed Controls and Programs
    Research and specify security controls needed to close the security gaps in BRI.
    Also, be sure to include a description of the following programs for securing BRI:
    • Security Awareness and Training Program (i.e., communications to employees regarding
    security)
    • Privacy Protection Program
    • Business Continuity/Disaster Recovery Program
    You should justify the need for the agency to invest in your recommendations.
    Document your findings and recommendations from this step in the “Interim Security
    Recommendations Report.”
    6) Communicate the Overall Findings and Recommendations
    Integrate of your earlier interim reports into a final management report. Be sure to address:
    • Summary of the Current Security Situation at BRI (from Step 1)
    • Risk Assessment Methodology (from Step 2)
    • Risk Assessment Plan (from Step 3)
    • Risk Assessment Findings (from Step 4)
    36
    • Security Recommendations Report (from Step 5)
    • Conclusions
    Also provide a presentation to management. The presentation should consist of 1520
    slides. It should
    include audio narration (directions are found at: https://support.office.com/enau/
    article/Addnarrationtoapresentation0b9502c65f6c40aeb1e7e47d8741161c).
    The narration should also be
    captured in the slide notes.
    Prepare a peer evaluation report.
