The current state of affairs is that most information security professionals use the concepts of Confidentiality, Integrity and Availability for audits, consulting projects, risk assessment and management, and development of new standards. These concepts present a series of problems that have yet to be solved:
They're incomplete. Some professionals suplement them with concepts like Possession, Utility, Risk, Authentication, Authorization, Audit, Non-Repudiation and Accountability. This means performance and delivery vary greatly depending on what professional or company you use.
- They're ambiguous. Many professionals and even published standards give different definitions of Confidentiality, Integrity and Availability. This adds more undesirable variance.
- They are not operational. Consequently, Threats, Incidents, Vulnerability and Weakness among other concepts can't be reliably defined in terms of Confidentiality, Integrity and Availability reliably, increasing the ambiguity of definition. Even seasoned professionals don't agree on just what an Incident or a Vulnerability is. If you can't agree on what something IS, how can you manage it?
- They don't have units of measurement. This makes it impossible to manage information security quantitatively. Bye, bye, optimization of resources.
The use of ambiguous, incomplete, not operational concepts without units of measurement has created a number of problems for information security management. Communication with between specialists and non-specialists in information security is difficult. Demonstrating the value of information security is difficult. Generally speaking, the use of these proxy concepts that don't add value makes information security management more difficult that it needs to be. Time is wasted, security projects that need funding don't get it, and trendy projects with little return get the green light. Luckily, change is possible.
Reasons to participate
- To prove you skills as an information security consultant and win the prize.
- To show off the worth of the professional certificate you hold and win the prize.
- To prove that Confidentiality, Integrity and Availability are indeed fundamental an useful concepts.
- To prove that Confidentiality, Integrity and Availability are neither necessary nor useful concepts.
The O-ISM3 Challenge
The O-ISM3 Challenge presents participants with a Use Case scenario (see below). The Use Case is a fictional Travel Agency in Madrid, Spain. Participants will act as information security consultant who need to determine what are the information security needs of the Travel Agency. Please note that there is a difference between finding out what the Travel Agency needs and what the Travel Agency might do regarding information security. If we were to compare the security practices of the Travel Agency with some standard, we could find out that the Travel Agency is not doing everything that a standard says can be done. There is a difference between doing everything that is standards state is possible, and everything that meets the needs of the business.
Determining the security needs of the Travel Agency will enable the consultant to determine the reasonable security measures to be applied, which are likely to be different, and cheaper, than all the security measures that could be taken.
In order to prove that they can successfully determine the security needs, the participants have to create a list of Questions to ask the Travel Agency managers or employees. This should be easy, since all the answers are included in the Use Case, and they will be listed individually in a spreadsheet that the participants will have to fill out.
Participants have a choice:
- CIA Option: Questions can ONLY ask about Confidentiality, Integrity and Availability.
- O-ISM3 Option : Questions can NOT ask about Confidentiality, Integrity or Availability.
Development of the Challenge
- Participants can sign-up between the 28th of February and the 14th of March (CET Timezone).
- To participate there is a registration fee of 5 euro payable using the"Register via PayPal" button below.
- Communication between the participants and Inovement will be only through the mail address used to register and firstname.lastname@example.org
- The challenge is limited to 500 participants.
- Every participant will receive a copy of a spreadsheet with the Answers and a registration number within 24h of registration.
- In the spreadsheet, the participant must choose either the CIA Option or the O-ISM3 Option, and mention any information security professional certifications they hold.
- Each participant must fill in Questions that would give the Answers provided and send the spreadsheet attached in an e-mail to email@example.com, with their registration number in the subject of the mail.
- Questions will be evaluated. A single ambiguous question, where the answer is not a perfect match causes the participant to FAIL the challenge (Example of FAIL: "What is the Integrity of the Data?· for the answer "Data needs to be kept for 5 years", example of PASS: "When does the system needs to be Available? for the answer: "Between 8 and 5 Monday to Friday") .
- Grammatically, logically inconsistent questions, not in the English language, or longer than 255 characters or inclusion of malicious macros will result in a FAIL.
- For the CIA Option failure to use at least one of Confidentiality, Integrity and Availability (or Confidential, Integer, Available) in any question will result in a FAIL.
- For the O-ISM3 Option using any of Confidentiality, Integrity or Availability in any question will result in a FAIL.
- All answers must be sent by midnight on 16 of March (CET Timezone).
- Those who have PASSED will be announced on 24 of March. The best ones will be published.
- The results of the entry evaluations may not be contested.
- The names of the participants will not be published without their permission.
- A 500€ prize and a free seat for an O-ISM3 Course will be awarded. The winner will be chosen from those who PASSED and will be given to the one with the most significant digits (two at least) in their registration number matching the first prize of Loteria Nacional of 29 of March (a random number). The prize will be paid within seven days via Paypal to the same account used to register.
- The number of participants both the total number and those with correct answers for both Options will be published, along with an analysis of the results comparing how the CIA Option and the O-ISM3 Option fared, and what that means for the use of concepts like Confidentiality, Integrity and Availability.
If you want to get posted on the development of the Challenge, follow us on Twitter, or request begin added to our mail list.
If the number of participants who PASS using the CIA Option is higher than the number of participants who PASS using the O-ISM3 Option, this will indicate that Confidentiality, Integrity and Availability are valid concepts in order to analyze the security needs of a company like Ambiguous SL. If the number of participants who PASS using the O-ISM3 Option is higher than the number of participants who PASS using the CIA Option this will indicate that Confidentiality, Integrity and Availability are not particularly useful in order to analyze the security needs of a company like Ambiguous SL. As a secondary result, we will compare how different information security professional certificate holders performed.
The Use Case
Ambiguous SL is a travel agency located in Madrid, Spain. Their business is selling retail travel packages both online and through their offices, which are street level on a main street. The most important system they own and operate is the Package Sales System, which they use for advertising, sales, and bookings. This system interfaces with the Amadeus GDS system (checking availability and bookings), with VISA (payments), and with an equivalent system of a Moroccan partner (MTravel), as it is a popular destination for Spanish tourist and represents a significant part of the company's business.
The owner of Ambiguous SL has put Myrna in charge of IT, among other responsibilities. Myrna has hired you do find out which security measures (controls or processes) would provide the highest return of investment for Ambiguous SL. Myrna will take care of implementation. Your first (and only) task is to make an assessment of Ambiguous SL security needs.
Myrna has named Ignatius as the project manager for the Package Sales System. He is an employee of the company (Confederacy SL) that develops and maintains the Package Sales System for Ambiguous SL.
The Package Sales System functionality is as follows (please note this a Use Case, so it is simpler than a real life case):
- Create, Modify and Delete Travel Packages.
- Sell Travel Packages both online and at the office.
- Receive feedback from customers and the public in general.
- Send Travel Package offers to subscribers.
- Manage Claims and Issues.
A high level view of the Package Sales System Database reveals the following data resources:
- Travel Package Archive
- Sales Archive
- Feedback Archive
- Offers Archive
- Claims, Feedback and Incidences Archive
The following list of actions can be performed on each data resource:
- Travel Package Archive: Create, Update, Retire, Publish, Unpublish.
- Sales Archive: Book, Release, Sell, Refund, Update.
- Feedback Archive: Create, Update, Close.
- Offers Archive: Create, Update, Retire, Publish.
- Claims, Feedback and Incidences Archive: Create, Update, Close
- Sales Statistics Report Archive: Create, Close
There are certain requirements about who can do what, and where they can do it:
- Only the sales manager can Create, Update and Publish Travel Packages.
- Each salesperson can only view the personal information of his or her own clients.
- Only the sales manager and the person assigned to Feedback and Claims can view the personal information of all clients.
- Only the owner of the company can access the Sales Statistics Report.
- Only the sales manager can create Offers
Certain parts of the Package Sales System are licensed, namely the Operating System, Application Server and Database.
As the company and systems are located in Spain, the Package Sales System needs to comply with the Spanish Privacy Law (LODP). Since the Package Sales System manages VISA payments, it needs to comply with PCI-DSS.
Some of the users of the Package Sales System are employees of Ambiguous SL, some are temps from Adecco. The administrators of the Package Sales System are employees of Confederacy SL. The general public of Spain is a user and they can purchase Travel Packages through the application. The application does not serve the public of countries other than Spain. Persons under the age of 18 can ask for feedback and signup for offers, but they can't purchase Travel Packages.
The system is located in a properly conditioned room inside the office. The system interfaces with Internet via a high speed fiber optic connection. The system interfaces with the interconnected systems and users via mail, file transfers and a VPN that connects directly with the MTravel network.
The system is expected to work 24x7, but because of maintenance stoppages of no more than one hour per week during no business hours (from 9 to 5 from Tuesday to Sunday) are acceptable. The longest time that the system can be offline during business hours is 2 hours, because sales can be performed with TPV and handwritten notes can partially replace the use of the system. In case of a major malfunction of the system, it would be acceptable to lose one day of data, since most data could be reconstructed checking with VISA, Amadeus and Mtravel. It is understood that all "live" transactions would be lost in case of an incident.
Data needs to be archived for 5 years in order to meet tax regulations. After ten years data should be deleted permanently, as customer behaviour changes over time and data is no longer useful for Business Intelligence.
Sales representatives and customers sometimes make mistakes entering data. This is acceptable as long as there is no more than one percent of the records contain innacurate information.
In order to create an account in the Package Sales System, potential clients can login using Facebook or create an account linked to their email address. They can unlink or delete the account at any time, but that does not delete any data in the database if they have purchased a Travel Package, even if they cancelled the purchase. In order to create an account in the Package Sales System, the Sales Manager sends an email to the Administrator. The email states what functions the user should be able to perform. The general public doesn't need an account to provide feedback or sign up for the Offers newsletter.
Customer who lose their passwords to the Package Sales Systemcan request a new one and a link will be sent to their email address. Users who lose their password to access the Package Sales System need to physically visit the Administrator, who resets the password and give it to them in a written note.
As some Offers expire at midnight, the Package Sales System should prevent customers from purchasing Travel Packages after they have expired, even by a few seconds.
There is a development environment, that Confederacy SL maintains in their own data center, and a pre-production environment, at Ambiguous SL office.
The current administrator is subscribed to email lists that notify him of security updates. The Administrator has configured the system using security guidelines found on Internet for every component. Security patches have not been applied since a patch caused a half day downtime.
The Administrator changes about once every six months.
The system has no malware protection.
The domain has been registered with Piensasolutions.es. The digital certificates used by the system are from Thawte. No one has been assigned with the responsibility to manage the domain or the certificates.
The systems logs all the sales activity, but not any other activity.
There is no Firewall. The internet connectivity provider (Telefonica) provides a service that is supposed to provide "clean" traffic.
No part of the Package Sales System is located in a publicly accesible location.
No part of the Package Sales System is accesible via Mobile application, but there are plans to incorporate a solution for this.
No part of the Package Sales System is exposed to extreme environmental conditions.
