Access Control Systems

At their most basic function, access control systems provide or deny the ability to enter a building, facility, or gated area. A number of components can be utilized in these control systems. The typical system allows or denies a person's physical entrance. Their ability to enter an area may be dependent on payment or authorization. Basic controls that we encounter on a daily basis include turnstiles, such as what you would see with an underground subway system, or a card swipe lock, which requires a programmed card to bypass. Other components include parking gates, doors, elevators, and other physical barriers. These types of access control are common sights.

Many businesses and industries are increasing their use of access control systems, particularly those that utilize badges and card swipe locks. These provide greater access control to areas that may contain personal information, like patient records at a doctor's office or a student's dorm. These systems are essential in ensuring the protection of both people and sensitive information.

Historically, the first access control systems were basic locks and keys. However, locks can be picked and keys can be replicated. Digital types, in association with close circuit television systems and DVR/NVR recording, allow you to not only allow entrance to certain individuals, but to also monitor that those are the people entering.

More technically advanced access control systems utilize digital computer technology that resolves the limitations of a simple lock and key. Entrance can be limited to only those who have the card with the appropriate entry credentials.

Continental Access provides you security systems that are useful for any industry or need.

Bringing Unbreachable Access Control to the Small Business World

Access control and security are pressing concerns for virtually all small and medium enterprises in the UK. No matter the industry in which a company is involved, the same security issues arise and, for most organizations, the same problems of finding robust solutions that protect premises from unwanted trespassers exist.

Currently external and internal access control to most buildings is by use of keys, keypads and swipe cards. All of these methods have obvious drawbacks as keys and swipe cards can be stolen or copied in order to gain illicit access to a premise whilst keypads rely on a user’s memory and integrity to maintain a trouble-free access control system for any organization.

By contrast a biometric access control system only allows authorized individuals entry to an area by inspecting an array of human physical characteristics that are unique to each and every individual on the planet.

Systems developed in the last five years can authenticate a person’s identity with total accuracy by comparing fingerprint patterns, iris structures and even facial features against a database that contains those same details and measurements of individuals allowed access to a particular building.

The obvious advantages of biometric access control systems based on unique human physical attributes are that it is impossible for an unwanted intruder to gain access by theft - there is nothing that can be stolen or replicated - and neither does a biometric system rely on the honesty and memory of an employee in the way that a keypad system does.

In simple terms a biometric access control system is extremely secure because it relies on unique human physical attributes that cannot be stolen or replicated. The system is unbreakable by any unauthorized personnel or unwanted visitors. It is an ultimate and incorruptible key.

Many people are aware of biometrics because we see the media stories about the technology now being integrated into passports so that more accurate citizen identifications can be made at airports by passport control officials. News stories such as these give a misleading impression that biometric access control is very expensive to install and is the preserve of governments, multinational corporations and extremely well-heeled celebrities.

In actual fact, top quality biometric systems are now being designed and sold with the needs and resources of small and medium sized businesses specifically in mind. Normally utilizing fingerprint pads located outside entrances, the retail systems now available have impeccable pedigree as they use the same technology that has been rigorously and repeatedly security tested by governments and multinational corporations keen to protect their own interests at almost any costs. Such systems can now be commonly installed and operated by smaller businesses with no upfront costs and a low monthly service charge.

At first glance the types of businesses that can benefit from the added security of biometric access control are self-evident: leisure centres; retail outlets; industrial unit tenants; serviced office blocks and so on. Almost all companies operating in sectors such as these can improve their security and access control arrangements by installing biometric fingerprint pads at both external entrance points and at restricted areas within buildings.

But biometric access control systems should not just be thought of in the context of upgraded preventative security measures. For many companies, the installation of an unbreachable access control system is a real business positive! As well as entitling many organizations to lower commercial insurance rates, the presence of a biometric system can actively bring in valuable extra customer business.

Owners of businesses that protect and store securely the property of others can use biometric access control as a value-added selling point. Bonded warehouse, self-storage operators and private safe deposit box companies are all examples of enterprises that can gain extra income from the installation of biometric access control.

More important than the protection of goods to many businesses is the protection of people. Nurseries, retirement homes and hospices are all businesses that can offer added peace of mind to existing and potential customers by installing biometric access control systems.

At the moment the potential for the use of biometric access control within small and medium sized enterprises has scarcely been touched by those who sell systems. This will change dramatically as business proprietors become aware of the advantages of biometric systems over conventional access and security measures employed currently.

And given that robust proven systems are already available at low cost outlay, it is actually very probable that the inevitable move towards biometrics is more likely to become a stampede among small and medium sized business proprietors over the next couple of years.

Access Control - Who Has Access To Registrant Data?

As a busy event planner – in seemingly endless contact with venues, catering companies, and the oh-so-demanding event sponsor – can you afford to spend time developing registration spreadsheets, keeping track of each registrant’s information, recording travel and hotel details, and taking and processing credit card info? For most event planners, the answer is a resounding no. The process of registration is often the straw that breaks the camel’s back, causing an event planner’s stress level to rise to supreme heights. Keeping track of all the technicalities of registration is a full time job that many planners are still attempting to juggle along with planning the event itself.

So, with the vast reach and simplicity of the internet, why are so many event planners hesitant to switch to an online registration company that will take care of all these technicalities for them? The answer is simple: they either don’t know about it, or they are worried that such companies could in fact complicate their lives. How can I know that information being put out on the internet will be safe? What if my registrants’ information is compromised? Will the online registration company use or sell my registrants’ information after they have it in their System?

With the right company, all of these questions can be avoided because registrants’ information will be secure and held safe for the sole use of the event planner. Even more importantly, with the right registration company, credit card information will be encrypted to the highest degree allowed by law, guaranteed by a SSL (Secure Socket Layer) encryption testing company, such as Thawte. Once you have chosen a company that you know to be secure, you will enjoy features such as an event website with its own URL for registration, custom reports, and the ability to export reports to a wide variety of formats. Using a safe and secure online registration system can simplify the event planning process while increasing registration! And you can be sure that registrants’ personal and financial information will be protected at the highest possible levels.

Registrant and event planner information that is protected to the highest degree possible offers you a guarantee that the information will be stored exclusively for the event planner’s use and will only be stored as long as is necessary. Holding to such standards, ensures that the event registration system is highly resistant to any breach, but if a breach does, in fact, occur, the system will have been monitored so effectively that it can be traced a remedied with accuracy and speed. A vulnerability recovery plan like this one is an essential part of upholding a strong security system to ensure that the system will not be breached. Your registrants will know that their information is safe.

Manually collecting registrations has long been one of the most tedious jobs involved in the event planning process, but it is no longer necessary for event coordinators if they choose a company that will offer the highest possible level of security so that they can enjoy the ease of use of such a comprehensive online registration system. With no need to worry whether or not their information will be hacker-safe, registrants will flock to your event because registering online is truly a far easier process than completing registration be old-fashioned snail-mail. Although giving up control over such a vital piece of the event planning process can be a frightening concept, doing your research to find a company that offers the strongest security for your registrants’ data, will save you time to deal with all of the other details of planning your next fantastic event.

Burglar & Intruder Alarms-Protecting Home & Family-Business Access Control

Not too long ago our burglar alarm was a dog and very good neighbours. Today we have very sophisticated systems that few occupiers really understand.

No matter whether your intruder alarm is a basic DIY system, wireless burglar alarm or complex state-of-the-art integrated access control and security system, the principle is very much the same.

Let's take a look at how Circuit Alarms, Basic Motion Detectors, and more Advanced Motion Sensors work.

Circuit alarms come in two types: closed circuit and open circuit.

The concept is identical: electricity travels through the circuit protecting a door or window. With an open circuit, the current is not completed until the door or window is open, this triggers the alarm. The downside to this intruder alarm system is that all the burglar needs to do is cut the wires; this prevents the circuit from being completed.

Whereas a closed circuit intruder alarm, the current is broken when the door or window is opened, thus triggering the alarm.

All intruder alarms have a control panel and vary in complexity. They either have a keypad or traditional key to arm and disarm the burglar alarm. It is likely to have 'zones'; each zone represents a protected area. When the intruder alarm is activated, the control panel will sound internally as well as repeater sounding much louder through an external box, which may also flash. The control panel and external box will keep sounding until it is reset with a predetermined code or key.

The control panel should be sited in a place where the burglar cannot easily find and interfere with it.

Closed circuit burglar alarms are generally used as perimeter protection but be mindful that although the circuit goes around the door or window frame, if a panel is remove from the door, a window is removed without breaking the circuit, the intruder alarm will not be activated.

A motion detector offers an excellent back up. You may see these called PIR detectors and are located high up in corners, flashing each time they detect motion, even when the burglar alarm is off.

You can surround your home with a closed circuit alarm system that will sound the alarm when an intruder breaks the circuit. But once the criminal is inside, you need a whole different approach to how burglar alarms work. Motion detectors can assist in opening automatic doors and gate by detecting people approach. They can switch lights on too.

More advanced are passive infrared (PIR) motion sensors that see the heat given off by a person's body. The PIR measures the average room temperature and triggers the alarm when the energy rises rapidly, particularly when a human, whose average body temperature is 98.6 degrees, enters a room with an average of say 80-degrees

Don't worry about setting the alarm off when you enter a room, generally there is delay of a few seconds enabling you to reach the control box and disengage the alarm before setting it off.

If you have pets, don't forget to inform your security consult so that special PIR units can be sited in such a way that allows pets to roam without activating the system. . There are more advanced motion sensors, photo-sensor motion detectors for example. A beam of light is shone across an area in your property. When someone walks through the beam, it is broken and the sensor triggers the alarm.

A good intruder alarm system would combine both circuit and motion sensor alarms, thus providing you with two lines of protection against burglars

Medical Billing, HIPAA Compliance, and Role Based Access Control

HIPAA compliance requires special focus and effort as failure to comply carries significant risk of damage and penalties. A practice with multiple separate systems for patient scheduling, electronic medical records, and billing, requires multiple separate HIPAA management efforts. This article presents an integrated approach to HIPAA compliance and outlines key HIPAA terminology, principles, and requirements to help the practice owner to ensure HIPAA compliance by medical billing service and software vendors.

The last decade of the previous century witnessed accelerating proliferation of digital technology in health care, which, along with reduced costs and greater service quality, introduced new and greater risks for accidental disclosure of personal health information.

The Health insurance Portability and Accountability Act (HIPAA) was passed in 1996 by Congress to establish national standards for privacy and security of personal health data. The Privacy Rule, written by the US Department of Health and Human Services took effect on April 14, 2003.

Failure to comply with HIPAA risks accreditation and reputation damage, lawsuits by federal government, financial penalties, ranging from $100 to $250,000, and imprisonment, ranging from one year to ten years.

Protected Health Information (PHI)

The key term of HIPAA is Protected Health Information (PHI), which includes anything that can be used to identify an individual and any information shared with other health care providers or clearinghouses in any media (digital, verbal, recorded voice, faxed, printed, or written). Information that can be used to identify an individual includes:

  1. Name
  2. Dates (except year)
  3. Zip code of more than 3 digits, telephone and fax numbers, email
  4. Social security numbers
  5. Medical record numbers
  6. Health plan numbers
  7. License numbers
  8. Photographs

Information shared with other healthcare providers or clearinghouses

  1. Nursing and physician notes
  2. Billing and other treatment records

Principles of HIPAA

HIPAA intends to allow smooth flow of PHI for healthcare operations subject to patient's consent but prohibit any flow of unauthorized PHI for any other purposes. Healthcare operations include treatment, payment, care quality assessment, competence review training, accreditation, insurance rating, auditing, and legal procedures.

HIPAA promotes fair information practices and requires those with access to PHI to safeguard it. Fair information practices means that a subject must be allowed

  1. Access to PHI,
  2. Correction for errors and completeness, and
  3. Knowledge of others who use PHI

Safeguarding of PHI means that the persons that hold PHI must

  1. Be accountable for own use and disclosure
  2. Have a legal recourse to combat violations

HIPAA Implementation Process

HIPAA implementation begins upon making assumptions about PHI disclosure threat model. The implementation includes both pre-emptive and retroactive controls and involves process, technology, and personnel aspects.

A threat model helps understanding the purpose of HIPAA implementation process. It includes assumptions about

  1. Threat nature (Accidental disclosure by insiders? Access for profit? ),
  2. Source of threat (outsider or insider?),
  3. Means of potential threat (break in, physical intrusion, computer hack, virus?),
  4. Specific kind of data at risk (patient identification, financials, medical?), and
  5. Scale (how many patient records threatened?).

HIPAA process must include clearly stated policy, educational materials and events, clear enforcement means, a schedule for testing of HIPAA compliance, and means for continued transparency about HIPAA compliance. Stated policy typically includes a statement of least privilege data access to complete the job, definition of PHI and incident monitoring and reporting procedures. Educational materials may include case studies, control questions, and a schedule of review seminars for personnel.

Technology Requirements for HIPAA Compliance

Technology implementation of HIPAA proceeds in stages from logical data definition to physical data center to network.

  1. To assure physical data center security, the manager must
    1. Lock data center
    2. Manage access list
    3. Track data center access with closed circuit TV cameras to monitor both internal and external building activities
    4. Protect access to data center with 24 x 7 onsite security
    5. Protect backup data
    6. Test recovery procedure

  2. For network security, the data center must have special facilities for
    1. Secure networking - firewall protection, encrypted data transfer only
    2. Network access monitoring and report auditing

  3. For data security, the manager must have
    1. Individual authentication - individual logins and passwords
    2. Role Based Access Control (see below)
    3. Audit trails - all access to all data fields tracked and recorded
    4. Data discipline - Limited ability to download data

Role Based Access Control (RBAC)

RBAC improves convenience and flexibility of systems management. Greater convenience helps reducing the errors of commission and omission in granting access privileges to users. Greater flexibility helps implement the policy of least privilege, where the users are granted only as much privileges as required for completing their job.

RBAC promotes economies of scale, because the frequency of changes of role definition for a single user is higher than the frequency of changes of role definitions across entire organization. Thus, to make a massive change of privileges for a large number of users with same set of privileges, the administrator only makes changes to the role definition.

Hierarchical RBAC further promotes economies of scale and reduces the likelihood of errors. It allows redefining roles by inheriting privileges assigned to roles in the higher hierarchical level.

RBAC is based on establishing a set of user profiles or roles according to responsibilities. Each role has a predefined set of privileges. The user acquires privileges by receiving membership in the role or assignment of a profile by the administrator.

Every time when the definition of the role changes along with the set of privileges that is required to complete the job associated with the role, the administrator needs only to redefine the privileges of the role. The privileges of all of the users that have this role get redefined automatically.

Similarly, if the role of a single user is changed, the only operation that needs to be performed is the reassignment of the user profile, which will redefine user's access privileges automatically according to the new profile.

Summary

HIPAA compliance requires special practice management attention. A practice with multiple separate systems for scheduling, electronic medical records, and billing, requires multiple separate HIPAA management efforts. An integrated system reduces the complexity of HIPAA implementation. By outsourcing technology to a HIPAA-compliant vendor of vericle-like technology solution on an ASP or SaaS basis, HIPAA management overhead can be eliminated (see companion papers on ASP and SaaS for medical billing).

Access Control List in .

BalajiAccess Control List in .NET Framework

Once you complete developing a web application, you need to secure it. This is when the aspect of security comes into picture. There will be some portions of your application which need to be secured from users. Securing an application may need extra hardware to build complex multi-layer systems with firewalls, and also some highly secure features. Security enables you to provide access to a specified user after the user is authenticated and authorized to access the resources in your web application. The Access Control List is used in the authorization process.

The basic concepts of security are Authentication, Authorization, Impersonation and Data or functional security. Authentication is the process that enables to identify a user, so that only that user is provided access to the resources. Authorization is the process that enables to determine whether a particular user can be given access to the resources that the user requests. Impersonation is the process that provides access to resources requested by a user under a different identity. Data or functional security is the process of securing a system physically, updating the operating system and using robust software.

Some elements of an operating system, the Internet Information Server (IIS), and the .NET Framework work in coordination to provide the features required to execute the security concepts mentioned above. For example, Windows 2000 uses its own list of user accounts for identifying and authenticating users. IIS identifies the users based on the information provided by Windows, when the users access a web site. IIS after identification of the users, passes this information to ASP.NET. Then the user information is checked for authorization.

To restrict access to the users for certain resources of an application, a process of identifying the users becomes a necessity. Authentication enables to restrict a user to access the resources by certain ways. It could be a combination of a username and password, a digital certificate, a smart card or a fingerprint reader. The validity of the information provided by the user helps identify the user, so that the user is provided access to the requested resources. The process of successful identification of the user implies that the user is authenticated.

After identification of the user is over, the next step is to determine whether the authenticated user has access to the resources. The process of determining the access to the resources for a particular user is known as Authorization. In Windows based systems, resources have an Access Control List, which provides a list of users who have access to that resource. The list also specifies the kind of access such as read, write, modify, and delete the resource, for each user. For example, if a user requests an ASP page, the operating system checks whether the user has Read access to the page and if the user has read permission, then the operating system allows the IIS to fetch the page. The IIS has authorization settings which enable the IIS to control the access of resources by users. File Access Control Lists are set for a given file or directory using the Security tab in the Explorer property page.
