Emanations[ edit ] Overview All electronic devices emit electrical signals. These signals can hold important information, and if an attacker buys the right equipment and positions himself in the right place, he could capture this information from the airwaves and access data transmissions as if he had a tap directly on the network wire.
Countermeasure Tempest: Tempest is the name of a program, and now a standardized technology that suppresses signal emanations with shielding material. Vendors who manufacture this type of equipment must be certified to this standard. In devices that are Tempest rated, other components are also modified, especially the power supply, to help reduce the amount of electricity that is used unlike the normal devices which have just an outer metal coating, referred to as a Faraday cage.
This type of protection is usually needed only in military institutions, although other highly secured environments do utilize this type of safeguard.
Tempest Technologies: Tempest technology is complex, cumbersome, and expensive, and therefore only used in highly sensitive areas that really need this high level of protection. Two alternatives to Tempest exist White Noise: White noise is a uniform spectrum of random electrical signals. It is distributed over the full spectrum so that the bandwidth is constant and an intruder is not able to decipher real information from random noise or random information.
Control Zone: Some facilities use material in their walls to contain electrical signals. This prevents intruders from being able to access information that is emitted via electrical signals from network devices. This control zone creates a type of security perimeter and is constructed to protect against unauthorized access to data or compromise of sensitive information. Shoulder Surfing[ edit ] Overview Shoulder surfing refers to using direct observation techniques, such as looking over someone's shoulder, to get information.
Fundamentals of Information Systems Security/Access Control Systems
Shoulder surfing is particularly effective in crowded places because it's relatively easy to observe someone as they: Fill out a form Enter their PIN at an automated teller machine or a POS Terminal Use a calling card at a public pay phone Enter passwords at a cybercafe, public and university libraries, or airport kiosks. Enter a digit code for a rented locker in a public place such as a swimming pool or airport.
Shoulder surfing is also be done at a distance using binoculars or other vision-enhancing devices. Inexpensive, miniature closed-circuit television cameras can be concealed in ceilings, walls or fixtures to observe data entry. To prevent shoulder surfing, it is advised to shield paperwork or the keypad from view by using one's body or cupping one's hand. Recent automated teller machines now have a sophisticated display which discourages shoulder surfers. It grows darker beyond a certain viewing angle, and the only way to tell what is displayed on the screen is to stand directly in front of it.
Certain models of credit card readers have the keypad recessed, and employ a rubber shield that surrounds a significant part of the opening towards the keypad. This makes shoulder-surfing significantly harder, as seeing the keypad is limited to a much more direct angle than previous models.
Taken further, some keypads alter the physical location of the keys after each keypress.
Also, security cameras are not allowed to be placed directly above an ATM. Object Reuse[ edit ] Overview Object reuse issues pertain to reassigning to a subject media that previously contained one or more objects.
But it usually cannot be implemented without the other two components. And even then the implementation may be very expensive. The reason is that the access management has to manage user access to the system. Therefore it needs to get into the way how user interacts with the system. Unlike the identity store and provisioning that are inherently back-end systems the access management is entwined into the application front-end. Access management is a dynamic part of the IAM solution: it works with the data in the real time.
So, what should I do now? You are probably reading this because you want to build a somehow complete IAM solution. There are many ways to do it. But perhaps the easiest and more universal way is this: Deploy a directory service if you do not have one yet. Or reuse the one you have.
Active Directory is a prime choice in Microsoft-oriented environments. Other environments will benefit from a native LDAP directory service. There is a very good choice of products on the market from over-priced commercial monsters to lean and elegant open source servers. Connect the applications to the directory service. All applications that are easy to connect.
But take care not to overdo this step. Keep in mind that directory service is just a database. If the application is lightweight and simple then it probably will be happy with LDAP.
Don't think twice and connect such application to LDAP. But the situation is quite different for more heavyweight and complex applications. These may have an LDAP authentication option but they frequently copy the user profile for internal use. You can connect them to LDAP as a temporary hack. But you need to go the next step to get a really satisfactory solution.
Deploy provisioning system. Use the provisioning system to maintain data in directory service, e. Also use provisioning system to fully integrate heavyweight applications.
Some basic self-service may be also a good idea at this stage. But do not push the project too far yet. Do just the most obvious steps that clearly bring immediate benefits.
And re-think. Now you are at the stage where the situation is mostly under control. The most pressing concerns were already addressed.
You are probably not under any immediate pressure now therefore you have time to decide what to do next. Perhaps the best strategy is to use the data from the provisioning system to analyze the real situation. The reports from the provisioning system can show how many accounts you really have, what proportion of them is active, what specific privileges they have, whether you can automatically link them together, how many orphaned accounts do we have or not and so on.
This is the real data. This is what you need to make a responsible informed decision about the next steps. Also listen to the users. What is the most severe problem for them?
Password management? Access requests? Based on this data you may want to do some of the following steps: Continue building a more formal RBAC structure and more automation policies, workflows in the provisioning system.
Deploy access management solution, e.
Extend the self-service interface. Integrate more applications. Do nothing. Surprisingly this may be a very efficient option at this stage. Whatever you do beyond this point costs more and delivers less benefit than the previous steps. Think of Pareto rule. It is important to know when to stop. How do I choose a provisioning product?
This is quite difficult part. There is a lot of provisioning products on the market. Their features, cost and suitability varies a lot. But basically there are three options: Big guns: If you choose a product from any "big name" company then you will get a very rich functionality, world-wide support and a huge pile of marketing brochures.
But all of this comes with a price tag.
It is important to consider price of the entire solution not just the cost of licenses. Support and especially professional services are even more important than licensing cost. Our experience shows that the "big name" products are quite elaborate and they have a long development history. But that also makes them quite difficult to use. Any engineer that can efficiently work with these products is not likely to ask for a low daily rate. The complexity and age of these products also mean that typical IDM project will take a long time months and needs a lot of skilled engineers.
Challengers: There is a bunch of smaller companies that offer alternative products. The price and quality differs a lot in this area. Also the availability of support and professional services may be an issue. It may be difficult to get an engineer that have sufficient knowledge of a product from this category. Yet another issue is a future of the product itself.
Acquisitions are quite common. And there is at least one precedent case of a technologically excellent product reaching end of life because of an acquisition. As these products are closed-source there is no practical step that a customer can take to avoid wasting his investment in such a case.

Open source: This is relatively new option. Few years ago there was no practical open-source provisioning system.Download the sample pages includes Chapter 4 and Index.
