Commercial Access Control
Access control is a security technique that regulates who or what can view or use resources in a computing environment. It is a fundamental concept in security that minimizes risk to the business or organization.
There are two types of access control: physical and logical. Physical access control limits access to campuses, buildings, rooms, and physical IT assets. Logical access control limits connections to computer networks, system files, and data.
To secure a facility, organizations use electronic access control systems that rely on user credentials, access card readers, auditing, and reports to track employee access to restricted business locations and proprietary areas, such as data centers. Some of these systems incorporate access control panels to restrict entry to rooms and buildings as well as alarms and lockdown capabilities to prevent unauthorized access or specific areas.
These security controls work by identifying an individual or entity, verifying that the person or application is who or what it claims to be, and authorizing the access level and set of actions associated with the username or IP address.
Organizations use different access control models depending on their compliance requirements and the security levels of information technology they are trying to protect.
Types Of Access Control
The main types of access control are:
- (MAC): A security model in which access rights are regulated by a central authority based on multiple levels of security. Often used in government and military environments, classifications are assigned to system resources, and the operating system or security kernel, grants or denies access to those resource objects based on the information security clearance of the user or device.
- (DAC): An access control method in which owners or administrators of the protected system, data, or resource set the policies defining who or what is authorized to access the resource. Many of these systems enable administrators to limit the propagation of access rights. A common criticism of DAC systems is a lack of centralized control.
- (RBAC): A widely used access control mechanism that restricts access to computer resources based on individuals or groups with defined business functions -- executive level, engineer level 1 -- rather than the identities of individual users. The role-based security model relies on a complex structure of role assignments, role authorizations, and role permissions developed using role engineering to regulate employee access to systems. RBAC systems can be used to enforce MAC and DAC frameworks.
- Rule-based access control: A security model in which the system administrator defines the rules that govern access to resource objects. Often these rules are based on conditions, such as time of day or location. It is not uncommon to use some form of both rule-based access control and role-based access control to enforce access policies and procedures.
- Attribute-based access control (ABAC): A methodology that manages access rights by evaluating a set of rules, policies, and relationships using the attributes of users, systems, and environmental conditions.
Use Of Access Control
The goal of access control is to minimize the risk of unauthorized access to physical and logical systems. Access control is a fundamental component of security compliance programs that ensures security technology and access control policies are in place to protect confidential information, such as customer data. Most organizations have infrastructure and procedures that limit access to networks, computer systems, applications, files, and sensitive data, such as personally identifiable information and intellectual property.
Access control systems are complex and can be challenging to manage in dynamic IT environments that involve on-premises systems and cloud services. After some high-profile breaches, technology vendors have shifted away from simple systems to unified access management, which offers access controls for on-premises and cloud environments.
Implementing Access Control
Access control is a process that is integrated into an organization's IT environment. It can involve identity and access management systems. These systems provide access control software, a user database, and management tools for access control policies,
- Can you use your mobile device? Yes
- Do you need WiFi to use? No
- How will this be affected by a power outage?
It will not be an issue if you have battery backup and/or a generator.
