CMIT 425 Risk Assessment Paper

GLOBAL FINANCE, INC. (GFI) Global Finance, Inc. (GFI) is a financial company that manages thousands of accounts across Canada, the United States, and Mexico. A public company traded on the NYSE, GFI specializes in financial management, loan application approval, wholesale loan processing, and investment of money management for their customers. The diagram below displays t he executive management team of GFI: Figure 1 GFI Executive Organizational Chart BACKGROUND AND YOUR ROLE You are the Chief Security Officer , hired by COO Mike Willy , to protect the physical and operational security of GFI’s corporate information system s. Shortly after starting in your new position, you recognize numerous challenges that you will be facing in this pursuit. Your primary challenge, as is usually the case, is less t echnical and more of a political nature . CEO John Thompson has been swept up in the “everything can be solved by outsourcing” movement. He believes that the IT problem is a known quantity and feels the IT function can be almost entirely outsourced at fractions of the cost associated with creating and maintaining an established internal IT department. In fact, the CEO’s strategy has been to prevent IT from becoming a core competency since so many services can be obtained from 3 rd parties. Based on this vision, the CEO has already begun downsizing the IT d epartment and recently presented a proposal to his senior management team outlining his plan to greatly reduce the internal IT staff in favor of outsourcing. He plans on presenting this approach to the Board of Directors as soon as he has made a few more refinements in his presentation . COO Willy ’s act of hiring you was, in fact, an act of desperation: the increasing operational dependence on technology services combined with a diminishing IT footprint gravely concerned Mike Willy, and he begged to at least bring in a n Information Security expert wit h the experience necessary to evaluate the cur rent security of GFI ’s infrastructure and systems . The COO ’s w orst nightmare is a situation where the Confidentiality, Integrity, and Availability of GFI ’s information system s w ere compromised – bringing the company to its knees – then having to rely on vendors to pull him out of the mess. COO Willy has reasons for worrying. GFI has experienced several cyber -attacks from outs iders over the past a few years: • In 2013 , the Oracle database server was attacked and its customer database lost its confidentiality, integrity, and availability for several days. Although the company restored the Oracle dat abase server back online, its lost confidentiality damaged the company reputation . GFI ended up paying its customers a large sum of settlement for their loss of data confidentiality. • In 2014 , another security attack was carried out by a malicious virus that infect ed the entire CEO John Thompson Vice President Trey Elway Executive Assistant Kim Johnson Executive Assistant Julie Anderson Executive Assistant Michelle Wang CCO Andy Murphy COO Mike Willy CFO Ron Johnson Director of Marketing John King Director of HR Ted Young network for several days. While infected the Oracle and e-mail servers had to be shut down to quarantine these servers. COO Willy isn ’t sure whether the virus entered GFI ’s systems through a malicious email, from malware downloaded from the Internet, or via a user ’s USB flash drive .

Regardless of the source of the infection, the company lost $1,700, 000 in revenue and intangible customer confidence. • In a se parate incident in 2014, one o f the financial cons ultants left his company laptop unprotected at the airport while travelling and it was stolen. It contained customer financial data and the hard drive was not encrypted . Financial reparations were paid to impacted customers. • In 2015, a laptop running network sniffer software was found plugged into a network jack under a desk in one of the unoccupied offices. It is apparent from the number of successful cyber-attacks that GFI is an o rganization severely lacking in information security maturity . COO Willy has commissioned you to perform a quantitative and qualitative ri sk assessment of GFI ’s infrastructure to determine where improvem ents could be made to reduce the risk of future attacks. CORPORATE OFFICE NETWORK TOPOLOGY The diagram on the following page displays GFI ’s Corporate Office Topology. The GFI network infra structure consists of a corporate WAN spanning 10 remote facilities that are interconnected to the GFI headquarters’ central data processing environment. Data is transmitted from a remote site through a VPN gateway appliance that forms a VPN tunnel with the VPN g ateway in headquarters. Through this VPN connect ion, remote office users access the internal Oracle database to update the customer data tables. Through your inspection of the VPN configuration you discover that the d ata transaction traversing the remote access connection to the corporate internal databases is not encrypted. Users are authorized to work from home and both dial-up and VPN remote access are available. Dial -up is provided via Private Branch Exchange (PBX) and a Remote Access Server and VPN remote access is provided via the VPN gateway. Authentication is password -based via MS -CHAP V2. Users are also able to take advantage of GFI ’s Bring Your Own Device (BYOD) policy and a Wireless a ntenna allows wireless networking within headquarters. WEP is used to provide wireless se curity to BYOD users.

The network perimeter between the Internet and GFI ’s internal network infrastructure is separated by two Borde r (Core) Routers. These Border Routers then connect to two Distribution Routers and the VPN G ateway . The Distribution Routers connect to a RAS Server , a Wireless Router that provides a bridge between the Wireless Antenna and the internal network, and two Multi -layer switches . The Multilayer switches connect to six ( 6) Access Layer VLAN switches that segregate the Accounting, Loan Dept, Customer Services , Mgmt, Credit Dept, and Finance VLANs. The Multi- layer switches also connect to a third Multi -layer switch that provides a connection to GFI ’s servers in the Trusted Computing Base subnet. The trusted computing based (TCB) internal network is situated in a physically separated subnet. A bulk of the data processing for GFI is handled by an Oracle database on a high end super computer located in the TCB and the TCB also contains an intranet web server used by the internal support team , a Software U pdate Services ( SUS) server used for patch management , an internal DNS server , an e-mail server , and other support personnel workstations. Although each corporate department is segregated physically on a different subnet , they share access to the corporate dat a in the TCB network. NOTE: The symbol represents a multilayer switch CONSIDERATIONS WHEN CONDUCTING THE RISK ASSESSMENT: This Risk A ssessment and your suggested security improvements are of critical importance. CEO Thompson is set on outsourc ing GFI’s IT competency and you’ve been told of a plan from COO Willy to outsource network management and security functions away from your department and over to a service integrator. COO Willy warns you that the political environment will on ly become more contentious over time; you must make a compelling case as to what value your department can bring over an integrator to provide security improvements in certain key areas without a significant increase to the IT budget . It is e xtremely important that you take into account the value of the assets being protected when selecting security controls to mitigate the risks (i.e. don’t spend $1000 to protect an asset worth $500). In addition to what you learned from COO Mike Willy about the previous exploits of GFI ’s vulnerabilities and what you gathered when reviewing GFI ’s network infrastructure, the COO has provided some additional information that he wants you to take into account:

1. Ever since an article ran in Fortune about GFI, the network engineers report that they’ve noted a significant spike in network traffic crossing into the internal networks. They report that they cannot be certain what or who is generating this traffic, but the volume and frequency of traffic is certainly abnormal. The management is very concerned over securing the corporate confidential data and customer information. S uggestions on improv ements to perimeter security and/or methods of identifying the source of intrusions should be presented in your risk assessment. 90 90 Wireless Antenn 9a0 2. The interrelationship between data and operations concerns COO Mike Willy. Increasingly, some of the ten ( 10) remote sites have been reporting significant problems with network latency, slow performance, and application time -outs against the Oracle database. The company’s business model is driving higher and higher demand for data, but your capability to respond to these problems are drastically limited. Suggestions on reducing network latency or increasing application response time and availability should be presen ted in your risk assessment. 3. Mobility is important for the organization to interact with the customers and other co -workers in near real -time. However, the C OO is concerned with mobility security and would like you to research best practices for mobil e computing. Security within the BYOD environment should be presented in your risk assessment. 4. Employees enjoy the flexibility of getting access to the corporate network using a WiFi network.

However, th e COO is concerned over the security ramifications over the wireless network that is widely open to the company and nearby residents. S ecurity within the wireless environment should be presented in your risk assessment. 5. The company plans to offer its products and services online and requested its IT department to design a Cloud Computing based e -commerce platform. However, the C OO is particularly concerned over the cloud computing security in case the customer database is breached.
