Access Control Systems
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 operations.
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 defense 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. Directory services and protocols, including the Local Directory Access Protocol (LDAP) and the Security Assertion Markup Language (SAML), provide access controls for authenticating and authorizing users and entities and enabling them to connect to computer resources, such as distributed applications and web servers.
Organizations use different access control models depending on their compliance requirements and the security levels of information technology they are trying to protect.
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 single sign-on systems to unified access management, which offers access controls for on-premises and cloud environments.
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, auditing and enforcement.
When a user is added to an access management system, system administrators use an automated provisioning system to set up permissions based on access control frameworks, job responsibilities and workflows.
The best practice of "least privilege" restricts access to only resources that an employee requires to perform their immediate job functions.
A common security issue is failure to revoke credentials and access to systems and data when an individual moves into a different job internally or leaves the company.

F.A.Q. about Access Control Systems
What is an ACS?
Interpretation of the abbreviation "ACS" - access control system. Includes hardware and software.
How does ACS work?
The system allows only people and cars that it “recognizes” into the territory to be able to identify.
For access we use contact and contactless keys, cards, fingerprints, secret code. Doorphones unlock the locks manually - when you click the "Open" button.
The intellectual access control system generates daily reports for each employee. Upon arrival at work, the staff opens the door with personal cards or puts the cards to the reader at the reception. We fix the time of breaks and the end of the working day.
What are the types of access control?
Access control systems are divided into autonomous and networked:
Autonomous access control systems are not connected to the computer. Suitable for small offices, cafes, shops, hotels. Autonomous systems are used on sites with 1–2 inputs.
Network access control systems are connected to a computer. Such systems serve complex objects: business centers, manufacturing, research institutes, hospitals, etc.
What is the access control system?
1. Blocking devices. Electromagnetic and electromechanical locks, barriers, gates, etc.
- Touch Memory contact keys - standard intercom keys;
- Touch Memory Access Keys;
- RFID contactless keys;
- Biometric sensor - fingerprint access;
- Keyboard for entering code.
3. Readers. Card readers, scanners, etc.
4. Controllers. Unlock the blocking device automatically or manually. Manual input is used in intercoms.
Is it possible to combine an access control system with a security alarm?
The unified access control system + security alarm system responds to an attempt to illegally pass through the access control point: open the door, unlock the turnstile. The alarm signal instantly arrives on the control panel of the security company, mobile phone manager or another responsible person.
Why combine access control with video surveillance?
When integrating with video surveillance, you get video recordings of all passes through access control points. Information from the cameras is transmitted to the monitors of the security in real time - the situation at the facility is easy to control.
Why do you need ACS maintenance?
Maintenance prolongs the life of the system. The equipment is inspected once a month, if necessary, fix minor problems and replace components. You save on capital repairs at the expense of preventive.
