Bamberger Corp. Completed Denver Expansion Project

SUMMARY AND BACKGROUND 35 36
In the early 2000s, Bamberger Corp completed a major corporate expansion project into the 37
Denver, Colorado metropolitan region. Although the expansion went smoothly, a lack of 38
focus on Information Technology Service Management (ITSM) and periodic architecture 39
technology refresh has allowed the infrastructure to fall into disrepair. Failure to invest into 40
upgraded equipment driven by ‘here is how we do business at Bamberger,’ has kept the 41
company largely in an antiquated technology environment. Modern concepts such as Cloud 42
Computing, Bring Your Own Device (BYOD), or wireless integration are largely foreign 43
concepts. We have noticed several major areas of concern in the area of information security. 44
Specifically, the implementing contractor did not provide architectural drawings, nor do they 45
seem to have implemented any Defense in Depth. In short, the Denver expansion did not 46
consider cybersecurity as a fundamental aspect of the Information Technology (IT) 47
environment. 48
49
The purpose of this request is to solicit proposals from various candidate organizations (Case 50
Study Groups), conduct a fair and extensive evaluation based on criteria listed herein, and 51
select the candidate (Case Study Groups) who best represents the direction Bamberger 52
wishes to go. 53
54
Bamberger Corp is a large business, with distributed quasi-independently operating mid-size 55
operating business units, that was founded in 1985. The company is focused on the 56
manufacturing of Gizmo1 and providing consulting services to start-up small businesses in 57
the Gizmo sector. In the past, Bamberger prided itself as a leader in the implementation of 58
best practice processes and solutions, and wants to take steps to return to this business 59
practice. Our client base consists of commercial businesses as well as local, state, and 60
federal government organizations. 61
62
Bamberger’s headquarters is based in New York City, with an established presence in 63
Washington, D.C., Chicago and Atlanta. Denver was selected as the central site for 64
Bamberger’s engineering and manufacturing functions as well as regional management 65
offices because of the company’s desire to significantly expand operations in Western states, 66
especially California. The Chicago location for the corporate university location was selected 67
due to under-utilization of the existing workforce. Atlanta was selected for its ability to 68
support Data Center operations. 69
70
1 GIZMO is a non-sensical term that refers to any kind of physical product or service that the Case Study Group
determines it to be. Depending on what the Case Study Group determines GIZMO to be, drives the direction of the
industry and thereby case study requirements of the project. If, for example, GIZMO is pharmaceutical in nature, the
laws, standards, regulations, privacy, security requirements, and industry specific best practices are driven by that
industry. If on the other hand, GIZMO is defined as financial, then the financial sector drives the direction of the
group. Step 1 of a successful (A-grade) response to the Case Study is therefore determining what GIZMO
represents!

92
2. PROJECT PURPOSE AND DESCRIPTION 93 94
The purpose of this project is as follows: In order to provide Defense in Depth for the 95
Denver expansion site, senior level management has determined that a comprehensive 96
information security management plan be available to ensure Bamberger keeps data secure. 97
Bamberger is seeking an information security management plan provider (Case Study Group) 98
that can provide a turnkey solution that integrates a Defense in Depth implementation, 99
integration of modern wireless and BYOD technologies, and adoption of Cloud within the 100
Denver computing environment. The proposal must include a system description that 101
addresses the Bamberger specification (course objectives, rubric) and are in line with the 102
following Bamberger Denver computing environment. 103
104
Project Description: 105
106
The bidder is expected to ask for clarification on any portion of this document via the 107
established communication channel (Ask the Professor | Case Study sub-thread). Failure 108
to use the designated communication channel or clarification outreach will likely result 109
in a less than favorable submission consideration. 110
111
There are a total of four buildings. Two 2-story buildings are co-located on a campus in 112
north Denver, conveniently near to both the airport and railroad terminus for shipping and 113
receiving. One of these buildings (DB1, for Denver Building 1, 12,000 sq.ft.) is for the 114
Engineering group. The collocated DB2 (16,000 sq.ft.) is for manufacturing. The two 115
Bamberger Corp. Completed Denver Expansion Project
4
buildings are connected by underground conduit and have plenty of spare multi-mode and 116
single-mode fiber strands. A third 2-story building (DB3, 8,000 sq.ft.) has been procured for 117
IT infrastructure and support staff, but it is located in the Denver Technology Center (DTC), 118
south of town. The fourth facility (DB4, 17,000 sq.ft.), per the desires of the new Western 119
Region General Manager, are four adjacent floors in a downtown office tower. 120
121
The building locations are: 122
123
• DB1/2: 4730 Paris St, Denver, CO 80239 124
• DB3: 5251 DTC Parkway, Englewood, Colorado 80111 125
• DB4: 16th Street, Denver, Colorado 80202. 126
The Engineering group has 450 employees. The Manufacturing group has 300 employees. IT 127
has 50 employees and the downtown facility houses 125 employees. The 125 personnel are 128
broken down into: 15 personnel for the Regional General Manager’s office (floor 9), 20 129
employees for Legal (floor 8), 15 personnel for HR (floor 8), and 75 employees for Sales 130
(floors 6 & 7). 131
132
The Engineering group has 300 people on the 2nd floor and 150 people on the 1st floor, as 133
there is a large lab on the first floor. All the Engineering people have their own dedicated 134
desktop PC and access to a printer, with an average of one IP addressable printer per ten 135
people. 136
137
The Manufacturing group has 100 employees, who each need a dedicated desktop PC and 138
access to a shared printer with the same user load as Engineering. The remaining 200 139
employees share a pool of 50 “public” PCs and 10 printers. 140
141
In DB4, all 125 employees have their own PC and access to a printer at a rate of one printer 142
per employee; this is due to the large number of user dedicated printers (e.g. the GM wants 143
his own printer) and special (e.g. high speed color) printers. 144
145
For the IT group, everyone has their own dedicated desktop PC, and access to a printer at the 146
same 10 to 1 ratio common in the company. Additionally, 30 of the 50 employees have 147
access to a dedicated Unix workstation, 10 for management and administrative functions on 148
servers, databases, etc., and 20 for a small development group building in-house applications. 149
150
IT manages a collection of server farms in DB3 dedicated to departments in the following 151
manner. The Engineering farm is composed of 75 Unix servers. The Manufacturing farm has 152
10 Unix servers. The Sales farm has 10 high availability Unix servers and 20 Microsoft 153
Windows servers running critical sales applications and databases. The Unix servers are 154
deemed 24x7 critical, and extra measures must be taken to protect against network failures 155
and security risks. The Corporate farm has 10 Microsoft Windows class servers, shared 156
among the HR, Legal and GM Offices groups. While not deemed operationally critical, 157
these servers do contain company sensitive information that calls for limited access due to 158
Bamberger Corp. Completed Denver Expansion Project
5
various privacy compliance mandates. Additionally, Corporate data must remain separated 159
from non-Corporate data at all times. 160
161
Some traffic estimates were developed based on typical file types. Engineering and Sales in 162
particular move fairly large data files averaging 30MB in size every working hour (6 a.m. – 163
9.m. Mountain time) for each employee. Engineering personnel data are extremely sensitive 164
and recent regulatory developments require that only the Western Region General Manager, 165
the General Counsel, the Engineering Manager and specific Engineering workforce have 166
controlled access to specific proprietary Gizmo data. Additionally, Sales has the need to 167
participate in desktop video conferencing using streaming technologies. Sales has both 168
transaction and analytical databases in the server farm. Corporate, Legal, HA, and 169
Manufacturing have no special traffic considerations as they move simple Microsoft Office 170
type of files averaging less than 1MB in size. In order to ensure a virtually transparent work 171
environment with the rest of Bamberger throughout the United States and to ensure product 172
quality, network delays for all Denver based employees must not exceed 2.5 seconds for 173
local network transactions, while wide area network transaction delay must not exceed 6 174
seconds. The bidder (Case Study Group) must demonstrate that each member of the given 175
Bamberger group will have at least the following bandwidth (considered an appropriate blend 176
of average and peek needs) to their local Denver servers: 177
178
• Engineering: 5 Mbps 179
• Manufacturing: 1.5 Mbps 180
• Sales: 5 Mbps 181
• Corp/Legal/HR: 1.5 Mbps 182
A design goal is to isolate traffic within groups as much as possible. Thus, the Director of 183
Manufacturing doesn’t want a heavy network traffic load from Engineering and Sales to 184
impact his production. Similarly, the Regional General Manager doesn’t want some clever 185
engineer sniffing the network and gaining access to highly sensitive, company private 186
documents and correspondence; similarly, for HR and Legal. Confidentiality, integrity, and 187
availability of the network and data are a must! 188
189
The Engineering and Sales servers back up files and services that are run out of the New 190
York office. This is done one night per week and the estimate is that this function requires a 191
fairly constant average of 500 Mbps for 12 hours. 192
193
All Denver personnel need access to the corporate intranet with applications running out of 194
New York. The average load of this traffic during working hours is estimated to be 15 Mbps, 195
with peeks of roughly 500 Mbps. 196
197
All Denver employees need access to the Internet. 198
199
The Western Regional Sales Director has his own local web servers (2) serving up sales 200
information, contact requests, and a significant amount of privacy and financial data, among 201
other information, to potential Western state customers. This information is kept up to date 202
Bamberger Corp. Completed Denver Expansion Project
6
with information found in the Sales server farm. Customer traffic to this site is pretty light, 203
no more than 10 Mbps average and 100 Mbps peek. Bamberger business forecasters predict 204
that 84% of Western state customer business will likely originate from California. 205
206
Bamberger does not own a cable plant within the greater Denver metro area and buildings are 207
connected via third party provider. 208
209
Bamberger’s current network address space used for all Bamberger locations other than 210
Denver is 135.172.128/22. Network engineers have already determined that insufficient 211
address exists to accommodate the existing Denver expansion despite the new address 212
location provided by W3C. Bamberger has made arrangements with W3C to obtain address 213
space 135.160/24. 214
215
Network robustness and security is a vital concern for Bamberger. Gizmo is a highly 216
advanced technical device whose production and operational function are highly sensitive. 217
As a result, detailed product data are strictly controlled by regulatory statue to specific 218
Corporate and Engineering personnel. There are 15 Corporate personnel (the Regional 219
Manager, two Senior Counsels) and 12 Engineers with access to the Gizmo data must be 220
isolated from the rest of Bamberger the personnel without access to Gizmo data. Bamberger 221
must have a method to bring non-sensitive data back and forth across the isolated 222
environments. Bamberger estimates that up to 20 GB of data, amounting to 6,000 files per 223
week, move between the environments. 224
225
While the rare outage of a few hours would be acceptable, anything longer than this would 226
not. Sales is particularly concerned about access to their 10 high availability Unix servers. 227
Therefore, the successful RFP bidder must ensure to address both continuity of operations for 228
all Denver operations and near 24x7 operations for the Sales high availability Unix servers. 229
230
Because of the forecasted California business base and our government partners, the 231
proposed plan must ensure compliance with published statues, policies, and best practices 232
within the Gizmo sector. 233
234
3. PROJECT SCOPE 235 236
The scope of this project includes all planning, architecture, and technical computation 237
artifacts necessary for demonstrating the veracity of the bidder’s proposed information 238
security implementation plan. The bidder is expected to deliver the following for review and 239
consideration (grade): 240
241
• Deliverable 1 – Requirements Definitions 242
o The submission must address both functional and non-functional requirements 243
either directly stated or implied in the provided documents (this case study 244
packet), any functional and non-functional requirements derived by 245
governance requirements stemming from the Gizmo definition (statute, 246
standards, industry best practice. etc.), and Bamberger expected outcomes 247

7
(syllabus course objectives). Additionally, requirements may arise as per 248
clarification questions invoked by the bidder and as documented in the official 249
communication channel (Ask the Professor/Case Study sub-thread) identified 250
above. 251
• Deliverable 2 – Project Plan 252
o The submission must provide a project plan and associated proposed 253
development methodology, a work breakdown structure detailing the 254
contribution of all participants, and rough project resource (budget) 255
requirement. 256
• Deliverable 3 – Enterprise Architecture Approach 257
o The submission must provide a description of the overall Enterprise 258
Architecture Approach, detailing how the proposed IT system (the network 259
and associated technology solutions) fits within the stated Bamberger vision. 260
• Deliverable 4 – IT Service Management Approach 261
o The submission must describe how the proposed IT system (the network and 262
associated technology solutions) and non-technology solutions of the 263
proposed IT services will be managed to ensure IT value. 264
• Deliverable 5 – Cybersecurity & Risk Management Approach 265
o The submission must identify the security approach (Security Framework) and 266
ensure correlation to an established Reference Architecture to ensure that the 267
established cybersecurity industry’s established Common Body of Knowledge 268
(CBK) domains2 are addressed. Detailed coverage must be included in the 269
areas of Software Security Engineering, Supply Chain Management, 270
Continuity and Recovery Planning, Security Testing & Evaluation, and Risk 271
Management and the associated assessment methodology. 272
• Deliverable 6 – Best Practice Policy Review 273
o The submission must identify ANY TWO PUBLISHED Security Policies of 274
any two organizations, and provide a comparison of the two policies.3 The 275
comparison must identify which of the two policies is in better alignment with 276
the documents identified in Deliverables 3 through 5, and explicitly identify 277
which of the Security Policies is better aligned for adoption (after 278
modification) by Bamberger. 279
280
2 (ISC)2 defines the domains as: Security & Risk Management, Asset Security, Security Engineering,
Communications & Network Security, Identity & Access management, Security Assessment & Testing, Security
Operations, and Security in the Software Development Life Cycle. 3 It is recommended that the identified Security Policies are selected from the same industry as that identified for
Gizmo under the System Description & Purpose section of the submission. This is NOT a requirement only a
recommendation. Selecting Security Policies from the same industry sector as Gizmo will allow for easier
revision/adoption of one of the policies as a baseline for meeting the Deliverable 7 requirement.

wireless, BYOD, or Cloud, not all three. The FINAL version of the DRAFT Security Policy SHALL include a sub-
policy that specifically addresses the selected implementation. If wireless is selected, this means that wireless
technology must be used to connect the Bamberger buildings, i.e. implementing LAN 802.11ac or any LAN
variation of the 802.11 standard DOES NOT count as implementing wireless. If Cloud implementation is selected,
the submission must provide details on the Cloud variant (IaaS, PaaS, or SaaS). If BYOD implementation is
selected, the submission must identify if the BYOD is corporate owned or individually owned, and provide a
management plan for either approach. 5 The AS-IS topology artifacts must be shown as described in this case study document, i.e. the bidder shall not
include network devices that are not specifically mentioned. The only exception is repeaters / hubs / switches /

homework, labs, quizzes, exams, and the case study. However, I understand that as individuals we all have strengths
and weaknesses. Some prefer theory, while others prefer a more applications focused approach. If you have an
application focus and know that you do not do well in theoretical areas (quizzes, exam), attempting one of these
additional extra credit projects may be an option for you. Again, this is extra credit. You cannot substitute one of
these projects for the final or midterm, or all quizzes since the point value of a project will NOT overcome the point
loss of not completing exams/quizzes. It is only a mechanism to recover lost points.
