What is access control?
Access control is a security system that enables an authority or business to control access at specific dates and time to certain areas of a community, building, or residence.
We can also describe access control as 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.
Why is access control so important? Having the ability to control who comes into your building at any point in time is critically important for the security, safety, and health of those who work or spend time in a facility. Any business or organization with heavy foot traffic will particularly benefit from access control.
How does access control work? There are three factors that authenticate information with access control devices: something the user knows (password, pass-phrase, PIN), something the user has (smart card or key), and something the user is (fingerprint). This access control technology is applied to the products and quality installations offered at TechShopNG that include card readers, biometric readers, video door phone, CCTV cameras, NVR/DVR, PoE switches, Modems and routers, Wireless adapter, Access points, Outdoor radio, USB Accessories, Power banks, etc.
Access control systems perform identification authentication and authorization of users and entities by evaluating required login credentials that can include passwords, personal identification numbers (PINs), biometric scans, security tokens or other authentication factors. Multifactor authentication, which requires two or more authentication factors, is often an important part of layered defence to protect access control systems.
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.
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.
