Access Control

What is access control system? A key component of data security

Access controls authenticate and authorize individuals to access the information they are allowed to see and use. Who should access your company’s data? How do you make sure those who attempt access have actually been granted that access? Under which circumstances do you deny access to a user with access privileges? To effectively protect your data, your organization’s access control policy must address these (and other) questions. What follows is a guide to the basics of access control: What it is, why it’s important, which organizations need it the most, and the challenges security professionals can face

Access control systems are the electronic systems that are designed to control through a network and they should have an access to a network. Access Control System recognizes authenticates and authorizes entry of a person to enter into the premise thereby giving complete protection ensuring security with the system.

Many access control system use network for communication purpose and information is communicated through these networks.

What is access control system?

Access control system provides security by giving flexible control over who is allowed to enter your premises.

Access control system is one of the most common used system in electronic door control using a card or a magnetic stripe which can be accessed by swiping through a reader on the door. These access control systems are used for security purposes.

The areas or organizations which require high security use different types of access control systems like bio metric, RFID, door controllers and card readers etc. Each access point may be controlled individually as per the requirement of company or organizations where high security is necessary. Network security is also important, especially in a company which handles sensitive data.

By this card access control systems allows access to enter into the premises limiting people to one side of the door. In some cases, physical access control systems are integrated with electronic ones by limiting the users allowing them to utilize the resources limited on a computer system.

Bio metric Access Control System:

The Bio metric Access Control System is a time attendance control system with fingerprint access and it tracks and records data of Visitors and Employees through its Access Software.

This is widely used in confidential places for its easy installation and high security. the entry of persons. The Attendance Software can be integrated with any existing payroll software and it gives automatic record of information generated by the Attendance System and this saves time and resources in recording. It increases productivity and profitability for any organization.

Fingerprint Identification

Fingerprint identification is the method of identification based on the different patterns of human fingers, which is unique among each person. It is the most popular way of acquiring details of any person and is the easiest and convenient way of identifying a person. An advantage of the fingerprint identification method is that the fingerprints pattern remains the same for a person throughout his /her life, making it an infallible method of human identification. The study of fingerprint identification is Dactyloscopy.

Proximity card Access Control System:

The proximity access control system is more confidential access control system. It ensures a safety environment and it is widely used in office, factory, bank, etc.. There are about 50 kinds of time zone settings and 5 open door groups.

The RFID tagis a microchip with an antenna in a compact package. The Tag can be attached to the object to be tracked through Radiofrequency. The Tag’s antenna picks up the signals from the RFID reader and then returns the signal usually with some additional data like the unique serial number. The RFID tags are too small so that it can be incorporated into any objects. Some Tags require battery while most of them do not need battery power and read at short distances using the electromagnetic induction. The Tag contains stored data that can be sent to several meters through the radio waves. The Tag does not need a line of sight with the reader and can be incorporated in moving objects also.

3 Types of RFID systems involving different types of tags:

Passive Reader Active Tag or PRAT – It has a passive reader that only receives the signals from an Active Tag. The range of the system can be many feet.

Active Reader Passive Tag or ARPT – It uses an Active reader and a Passive Tag. The Active Reader transmits signals to the Passive Tag and receives the signals from the Tag.

Battery Assisted Passive Tag or BAP- It also functions like a Passive Tag, but there is the battery to power the tag to send signals to the reader.

Access control is a method of guaranteeing that users are who they say they are and that they have the appropriate access to company data. At a high level, access control is a selective restriction of access to data. It consists of two main components: authentication and authorization, says Daniel Crowley, head of research for IBM’s X-Force Red, which focuses on data security. Authentication is a technique used to verify that someone is who they claim to be. Authentication isn’t sufficient by itself to protect data, Crowley notes. What’s needed is an additional layer, authorization, which determines whether a user should be allowed to access the data or make the transaction they’re attempting. Without authentication and authorization, there is no data security, Crowley says. “In every data breach, access controls are among the first policies investigated,” notes Ted Wagner, CISO at SAP National Security Services, Inc. “Whether it be the inadvertent exposure of sensitive data improperly secured by an end user or the Equifax breach, where sensitive data was exposed through a public-facing web server operating with a software vulnerability, access controls are a key component. When not properly implemented or maintained, the result can be catastrophic.” Any organization whose employees connect to the internet—in other words, every organization today—needs some level of access control in place. “That’s especially true of businesses with employees who work out of the office and require access to the company data resources and services,”

Access control policy: Key considerations
Most security professionals understand how critical access control is to their organization. But not everyone agrees on how access control should be enforced, says Chelsea. “Access control requires the enforcement of persistent policies in a dynamic world without traditional borders,” Chelsea explains. Most of us work in hybrid environments where data moves from on-premises servers or the cloud to offices, homes, hotels, cars and coffee shops with open Wi-Fi hot spots, which can make enforcing access control difficult.

Types of access control
Organizations must determine the appropriate access control model to adopt based on the type and sensitivity of data they’re processing, says Wagner. Older access models include discretionary access control (DAC) and mandatory access control (MAC), role based access control (RBAC) is the most common model today, and the most recent model is known as attribute based access control (ABAC).

Access control solutions
A number of technologies can support the various access control models. In some cases, multiple technologies may need to work in concert to achieve the desired level of access control, Wagner says. “The reality of data spread across cloud service providers and SaaS applications and connected to the traditional network perimeter dictate the need to orchestrate a secure solution,” he notes. “There are multiple vendors providing privilege access and identity management solutions that can be integrated into a traditional Active Directory construct from Microsoft. Multifactor authentication can be a component to further enhance security.”

Why authorization remains a challenge
Today, most organizations have become adept at authentication, says Crowley, especially with the growing use of multifactor authentication and biometric-based authentication (such as facial or iris recognition). In recent years, as high-profile data breaches have resulted in the selling of stolen password credentials on the dark web, security professionals have taken the need for multi-factor authentication more seriously, he adds. Authorization is still an area in which security professionals “mess up more often,” Crowley says. It can be challenging to determine and perpetually monitor who gets access to which data resources, how they should be able to access them, and under which conditions they are granted access, for starters. But inconsistent or weak authorization protocols can create security holes that need to be identified and plugged as quickly as possible. Speaking of monitoring: However your organization chooses to implement access control, it must be constantly monitored, says Chelsea, both in terms of compliance to your corporate security policy as well as operationally, to identify any potential security holes. “You should periodically perform a governance, risk and compliance review,” he says. “You need recurring vulnerability scans against any application running your access control functions, and you should collect and monitor logs on each access for violations of the policy.” In today’s complex IT environments, access control must be regarded as “a living technology infrastructure that uses the most sophisticated tools, reflects changes in the work environment such as increased mobility, recognizes the changes in the devices we use and their inherent risks, and takes into account the growing movement toward the cloud,” Chelsea says.

Access Control Software
From entry-level IP-based access control software to multi-location enterprise access control software, LINSTAR has a full line of access security software to build the right access control system based on the needs and requirements of your organization.

Biometrics fingerprinting
Biometric recognition technology is being used increasingly more in security, and fingerprint recognition (biometric fingerprint) is currently the most commonly used biometric technology for physical access control. It makes sense – people are already used to using fingerprints to verify themselves on their Smartphone and there are many benefits to fingerprint recognition. Enrolling and presenting a fingerprint is relatively easy. And the combination of a low price point and high accuracy levels make it a good choice for many access control applications, especially those where fewer people need access.

Network Access Control
(NAC) is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. ... A basic form of NAC is the 802.1X standard.

How To Select Attendance System

Security requirements of each company differ from one to the other depending on the strength of employees and type of premises. A quality attendance system can save both time and money of your company. There are various types of attendance systems but not necessary that each system will fit your company’s need. Attendance tracking system benefits both the company as well as employees. It helps the company keep track of the exact working hours of employees. On the other hand, it motivates employees to be more punctual and productive, thus benefiting their performance.

The primary reason why every company needs a digital attendance system is because of its accuracy. Earlier attendance was tracked manually that lead to errors and discrepancies. This results in an uneven paycheck. It makes the task of manager easy by providing error-free timesheet of each employee. Choosing the right attendance tracking system is crucial. Here are a few tips on how to select an attendance system.

  • Entrance Tracking System
  • Many of the companies need a strict tracking system to make sure the timings and working hours are followed. The entrance tracking system is a system that registers the employee’s in-time and out-time every time he/she enters or exits the office. There are different types of entrance tracking systems like electronic door lock & card access system and fingerprint access control and time attendance system. This helps to calculate accurate working hours and punctuality of the employee. Be it government body or a private company, if you have a large firm with more than 50 employees. This system can prove to be beneficial to track attendance record efficiently.
  • Payroll Integrated Attendance System
  • Payroll integrated attendance system is an access control and time attendance management system that tracks attendance and sends the data directly to the payroll software. This helps to calculate the working hours as well as absenteeism and thus results in an accurate payroll processing. Capturing the attendance data electronically also helps to get error-free payroll processing as it eliminates proxy attendance. It also benefits employees by calculating overtime. This type of attendance system is the need of every organisation as it reduces errors in attendance tracking and makes payroll process faster and accurate.
  • Online Attendance Tracking
  • Online attendance tracking system calculates attendance and time online. This cloud-based attendance system helps to track attendance even when the person is working on shifts, working from home or working in another city. This type of attendance tracking system is beneficial for companies that provide flexible working culture.
  • Negative And Positive Attendance
  • Access control systems for small business are different from the larger ones. Each company needs to decide if their company needs a positive attendance system or a negative one. The negative attendance system tracks only attendance eliminating the working hours. This type of attendance system is ideal for basic office jobs with 6-9 hours shifts. Positive attendance, on the other hand, calculates every single working hour. This type of attendance tracker is usually used in manufacturing units to calculate the productivity of each worker..

The primary aim of attendance tracking system is to ease the process of tracking time and absenteeism of employees. There are various factors like payroll, incentives, credibility, etc. that depend on attendance and working hours of the employee. A company doesn’t need to have only one system. You can integrate more than one tracking systems to get more accuracy and ease the process. For instance, you can have a door access control system with attendance as well as an online tracking system
