Case Study
Located in Sydney, Devon Accounting is a medium sized accounting company that offers tools and technologies to prepare all types of tax returns, including individual, sole trader, partnership, trust and company returns. They also provide a broad range of small business accounting services, including bookkeeping, financial statement preparation, tax planning, and advice.
The company headquarters is located in Sydney in a three-storey building with each floor being approximately 2000 square meters. The regional offices are located in Dubbo, Orange, Ballina and Kiama. All of the offices have at least one wireless access point and several of the offices have three or more. Each office has its own local internet connection. All the remote offices are connected to headquarters via a leased WAN connection.

Human Resources
Most of the workstations are running a mix Windows and Macintosh operating system. The graphics department uses Apple computers. Static IP addresses are typically assigned to common resources and DHCP is used for workstations. When the network was originally designed, IP subnets were assigned to different offices and departments. However, over time and as the network has grown, this subnet organisation has broken down. Over the last several years IP subnets have been assigned and reassigned without any regard to location.
All connections to the internet are protected by firewalls and network intrusion detection systems. All the workstations have virus-scanning software and a central console is used to push out signature updates. Workstations and servers are generally kept up to date with patches and service packs. The networking staff has employed all the standard security practices one would expect to find at most organisations of this size.
Although network security is well established in this company, there are still several IT security vulnerabilities that the company faces on a regular basis, mostly from human-machine interactions.
For example, a salesperson who frequently holds meetings in a conference room near his office was frustrated by the lack of available network connections for meeting participants. He decided to pick up an inexpensive wireless access point at his local electronics store and plugged it in. The salesman didn’t consider that the conference room was next to the parking
lot, making the access point available to the public.
Another problem they face is the amount of time it takes for the network administrator to locate infected computers whenever virus strikes throughout the enterprise. It is always a challenge to quickly identify, locate and disable the switch ports of machines infected. It can take up to 45 minutes per workstation for a potential total of 75 hours to locate and identify the infected users. This process usually includes logging into and querying routers and switches; and physically going to the switch to identify the port and trace the wire to the workstation. This process would have been even more difficult if the workstation happened to be in a remote location should the company expand in future.
This process is unproductive, costly and time consuming. Additionally, it assumes some knowledge of the network architecture. A new network administrator who did not possess knowledge of the network topology would have a much more difficult time locating the infected workstations.
Another serious issue company must address is IT security in order to protect its information and digital assets from compromise, theft or loss since Devon Accounting stores commercial assets and personal information on smart phones, computers, hard drives and online. The attack can be from a determined attacker outside, or an insider threat within your business. Devon Accounting could be the victim of hacking because of its online presence.
Devon Accounting has been increasingly using cloud computing for various business processes. Xero is accounting software stored in the cloud and provides integration between the small business’s accounting software and its accounting advisors. Xero have recently become popular a choice of tool at Devon Accounting. Office 365 is another tool used by some of the employees at Devon Accounting
One new management headache created by cloud computing is the fragmentation of where the files are stored. There is no consistency in the storage of these files which are stored on Dropbox, Google Drive, and OneDrive. It is easy to forget where the data is. Backing up all this data from different locations, or moving from one provider to another, is complex and difficult.
The use of mobile devices has increased exponentially and employees at Devon Accounting have taken up these devices enthusiastically because of convenience in the workplace. Employees felt they would get more tasks done on time if allowed to choose their own mobile tools – and even their sceptical bosses felt that the use of these consumer mobile devices in the workplace increases employee productivity.
This concept of ‘Bring Your Own Device’ (BYOD) – where employees use their personal devices to store business data – opens up new concerns and issues for Devon Accounting. In addition to worries about where exactly the business’s data might be ‘in the cloud’, BYOD means that any small – and easily-lost – device can easily contain vast amounts of relevant business information. Spreadsheets with pricing models, client lists, usernames and access can easily be stored on a mobile device.
Worryingly though, use of personal mobile devices, cloud computing services is not even mentioned in the current IT policy. Mobile devices can be gateways for new viruses, Trojan horses, and other IT-security problems and currently Devon Accounting is not be well-equipped to address such problems.
IT security planning is important for every organisation. Recently, you have been hired by your company to work as a IT Security consultant. Security controls at Devon Accounting was implemented 5 years ago. New systems, services and IT equipment have been added into the network since then. If any small or large disaster occurs, it is not prepared to recover itself after the disaster, the result of which is the high possibility that its business processes and functions would be disrupted for a long period of time. This would also result in different kinds of losses to the company.
Devon Accounting performs its different functions and business processes with the help of different IT equipment and computer systems. You are told that it mainly wants to implement a IT Security plan and implement for its IT system. There is different IT equipment in the company networks such as servers, workstations, printers, and so on. There are also web applications which employees use in their daily operation.
Current Security Controls:
SWOT analysis was used to identify the risks which led to the implementation of current security controls, and that was developed 5 years ago; since then a lot has changed in the company.
The security control was implemented by the Network administrator Bill Simmons whose role was to manage the day to day operation of the network. Maintenance and management of IT security was not Bill’s forte. The company at that time chose not to recruit a specialised IT security personnel. The plan was never revisited since and did not include various changes and updates made to the system processes and networking devices over the years.
Furthermore, the current security policy implemented at Devon Accounting only accounts for Assets, Access Control, Password Control, and Email. It is very surprising that for a business which deals with financial information of clients does not have any security policies in place for critical security issues such as Internet, Anti-Virus, Remote access, Outsourcing, Acceptable Usage, Web Access, Wireless Security, Server Access, Information Classification, Social Media, Cloud Computing Services and Storage, external devices etc. The consequences of employees purposely violating company’s rules for their personal gain should also be emphasised.
With the increase of employee numbers and relocation, company director Andrew Jacobs is concerned about the IT security of the system in place and the protection of customer data stored on the system and server.
With this and the recent reports on threats to the systems of companies worldwide, the Director together with the company’s CEO, are more aware of having a IT Security controls in place.
To address all issues the company has appointed you as an IT Security consultant, your primary role is to understand the system and processes of the company. For this case study, your Facilitator will act as an IT Manager who will provide you with the required information regarding different IT equipment, operations and business processes of the company.
You must consult your IT Manager (your facilitator) regarding the progress of each stage during IT Security planning process.

Memorandum – Devon Accounting Sydney Office
To: Staff
From: Director Andre Jacobs
Re: IT Security Issues and Requirements
Dear all
As you probably already know, the new Devon Accounting office is being relocated.
With this change of location and thinking about the greater security of our current and prospective customers, the company’s steering committee decided to hire an IT IT security consultant.
This hiring aims at the best structure of our security systems so that we can protect the data with customers, employees and all our database.
This decision was also made, after realizing some issues which needed to be investigated our system and procedures, such as:
Data loss during a recent malware attack on the company’s network which affected the company economically
Some of the operating systems used by staff are old and difficult to get support (Application and Operating Systems Patches)
Some of the staff are given remote access to but no monitoring is done, and no controls are in place (Remote access controls)
Staff have been receiving too many spams and malicious mails (Email filter and web content)
Network services such as printing and scanning down frequently due to Server issues (capacity and networking equipment)
Several laptops have gone missing from the office (Physical Security)
An occurrence of black out due to storm resulted in the whole systems to go offline resulting in productivity loss which was severe to the company (UPS)
Staff has been using easy to remember passwords and there have also been instances where a staff had written the password in a sticky note and placed it in the computer screen. Staff are also not locking their workstation in their lunch break. Serious issues can arise when the staff involved is responsible for processing payments and invoices (Password policies and authentications).
IT department is having difficulties dealing with issues relating virus, worms, and malware. Staff are using their personal USB in company’s workstation and accessing external websites which may have contained malicious codes (Firewall updates)
Some staff also access company’s network and Intranet via wireless devices. Staff are not happy about the speed being too slow or taking too long for the information to download (Wireless security and wireless access points)
Employees are using their personal wireless devices to store business data.
One new management headache created by cloud computing is the fragmentation of the files stored. There is no consistency in the storage of these files. Files are stored on Dropbox, Google Drive, or OneDrive. Backing up all this data from different locations, has become complex and difficult.
Besides these key points, the company’s management is concerned with possible data breaches caused by employees who normally access data from their mobile devices or remotely.
For these and other reasons, it is critical that we review our current security policies and prepare a detailed security plan and investigate what actions and measures can be taken.
We count on the collaboration of all during this process to assist IT security consultant to conduct a security analysis and recommendation on the controls to be implemented.

Techniques Used
Risk assessment questionnaire
The assessment team used a customized version of the self-assessment questionnaire in NIST SP-26 “Security Self-Assessment Guide for Information Technology Systems”. This questionnaire assisted the team in identifying risks.
Assessment Tools
The assessment team used several security testing tools to review system configurations and identify vulnerabilities in the application. The tools included NMAP, NESSUS, APPSCAN
Vulnerability sources
The team accessed several vulnerability sources to help identify potential vulnerabilities. The sources consulted included: SANS Top 20 (www.sans.org/top20) OWASP Top 10 (www.owasp.org/documentation/topte n.html) NIST I-CAT vulnerability database (HTTP://icat.nist.gov) Microsoft Security Advisories (www.microsoft.com/security)
Review of documentation
The assessment team reviewed system documentation, network diagrams and operational manuals.
Interviews were conducted to validate information.
Site visit
The team conducted a site visits and reviewed physical access and environmental controls

READ ALSO...   Brainstorming Exercise #2

In determining risks associated with the for Devon Accounting, the team utilized the following model for classifying risk:
Risk = Threat Likelihood x Magnitude of Impact
The loss of confidentiality, integrity, or availability could be expected to have a severe or catastrophic adverse effect on organizational operations, organizational assets, or individuals. Examples: A severe degradation in or loss of mission capability to an extent and duration that the organization is not able to perform one or more of its primary functions Major damage to organizational assets Major financial loss Severe or catastrophic harm to individuals involving loss of life or serious life-threatening injuries.
The loss of confidentiality, integrity, or availability could be expected to have a serious adverse effect on organizational operations, organizational assets, or individuals. Significant degradation in mission capability to an extent and duration that the organization is able to perform its primary functions, but the effectiveness of the functions is significantly reduced Significant damage to organizational assets Significant financial loss Significant harm to individuals that does not involve loss of life or serious life-threatening injuries.
The loss of confidentiality, integrity, or availability could be expected to have a limited adverse effect on organizational operations, organizational assets, or individuals. Examples: Degradation in mission capability to an extent and duration that the organization is able to perform its primary functions, but the effectiveness of the functions is noticeably reduced Minor damage to organizational assets Minor financial loss Minor harm to individuals.

Project task
Your task is to prepare a comprehensive report for Devon Accounting which must include reviewing the current security policies to preparing a detailed security plan and providing recommendation on actions and measures to be taken.
Task 1: Review organizational security policies and procedures
Determining the critical business requirements of the network is the first step in developing the security and controls design of the Devon Accounting network, as it means understanding what we need the network to achieve. Careful consideration must be given in the early stages as it will reap rewards later in the design, by identifying and addressing out the problems early.
To begin reviewing organizational security policies and procedures of the Devon Accounting network, you will need to:
Identify security requirements for Devon Accounting by reviewing the business requirements
Identify current security threats for Devon Accounting
Recommend a solution to the threats identified
Determine the need for the update in security policy for Devon Accounting. The updated policy must meet the obligations under the Privacy Act and Australian Privacy Principles.
List the job description for the IT security personnel
Recommend a methodology for performing security tests to these solutions
Task 2: Develop security plan
To begin developing a security plan for Devon Accounting, you will need to:         
Investigate and identify possible attacks and threats on the business
Evaluate risks and threats associated with the investigation (threat assessment matrix)
Recommend the security controls to be implemented. Update security policy and document the changes made. The security policy must follow the legal and ethical standards and must meet the obligations under the Privacy Act and Australian Privacy Principles. References for legislation and regulation could be considered from:
Australian Privacy Principles (‘APPs’).
