Access Control

What is access control?

Access Control is about controlling or monitoring specific access to physical locations, areas or assets. This process typically involves checking identity and determining whether access should be allowed.

In the world of information technology, access controls are used to regulate and permit access to resources. Access controls are the mechanisms that enforce security policies, by allowing or denying the resource access based on whether the request originates from inside or outside the organization, and whether the requester is authenticated.

Access control can be characterized as either an access-granted system or an access-denied system. In an access-granted system, authorizations are confirmed through secure systems such as biometric controls, while an access-denied system denies entry to those who are not explicitly authorized.


How does access control work?

Access control is a primary means of safeguarding and controlling your assets, people, technology, and information. Access management refers to the processes used by an organization to decide when, where and how resources should be accessed. A key control within access management is authentication, deciding that a user should have access to information or services.

Plans and projects are one thing, but how do they get done? How do you know that what you’re building meets stakeholder expectations—how do you know it works? Access control. Rules created by stakeholders, translated into requirements from the business. Confirmed by the team, down to the code level. Verified as functions work per design.

The digital world requires multiple layers of security to protect the sensitive data you collect and to ensure your information is never compromised. That’s just good business.

Access control is the only way to ensure that the data and content held on computer systems are secure against unauthorized access. As a society, we use technology all the time; machines that help us do our jobs better, play games, shop or manage our finances. With technology comes risk and threats to security.


What types of access controls are there?

Access controls are the technical and physical methods used to regulate an organization’s information systems. Access controls exist to ensure that only authorized individuals have access to specific IT resources.
Access controls technology allows you to control who can access your data and your applications, whether it’s on premise, in the cloud or both.

What types of access controls are there? There are two basic types: preventive and detective. Preventive controls block attacks before they occur; detective controls detect attacks after the fact.

Information security is important. Whether it’s to protect your data or network, keep things running smoothly or enforce governance, you need a partner that understands your specific requirements.


What’s the difference between physical and logical access controls?

Do you know the difference between physical and logical access controls? We do. You should too. Physical Access Control pulls physical doors shut, lets you into secure areas on your computer, and uses biometrics. Logical Access Control makes sure authorized people only have authorized access based on username and password.

The key differences between physical and logical access controls is that physical access controls are hardware-based, while logical access is software-based. Access security requires a physical access control system that helps to protect the premises. A logical system is one that controls, manages and records who was granted access to what data at what time.


Discretionary access control (DAC)

Discretionary access control (DAC) is the most common approach to access control. The granting of access rights is based on the identity of the user and/or process that tries to gain access.

DAC is a powerful set of security policies, tools, and automation that can be used to secure your environment. DAC permits the policy-maker to determine who should have access to what resources in a self-service manner. Used correctly, DAC can help you keep the right people away from the wrong data.

Discretionary access control, allows changing access rights on all objects in a Windows enterprise environment. DAC has full support for Group Policy Object (GPO) filters, security groups and protected groups, including inheritance of permissions.


Mandatory access control (MAC)

Mandatory access control (MAC) is an approach for restricting access to computer files and data based on the sensitivity (political, military, industrial, etc.) of the data. This contrasts with discretionary access control (DAC), where file access is determined based on the identity of a subject and assigned credentials.

Mandatory access control (MAC) is a form of access control that allows or denies an entity the ability to perform an operation on a system subject to security policy.
MAC is an effective complement to discretionary access control, which assigns privileges by user ownership. This model gives programmers a framework with which they can express and enforce both positive and negative security properties in their code.

Mandatory access control (MAC) describes a type of access control system in computer security that prevents unauthorized users from accessing resources.


Role Based Access Control (RBAC)

RBAC is a mature access control model for information security. RBAC allows users to control access to data or applications based on job function instead of user identity, broadening the security team’s ability to enforce separation of duty and non-repudiation.

RBAC’s role based access control system gives you the freedom to decide who does what in an organization, and it’s completely scalable. A role based access control system for managing privileged admin tasks, is dedicated to providing secure access to specific data and systems.
Role Based Access Control (RBAC) is the most effective way to secure and govern access to critical business data, files, and applications.


Attribute Based Access Control (ABAC)

ABAC is the most effective way to control access to systems and applications. With ABAC, not only does the user have to grant consent for information to be accessed, but they also need to explain why they want it. Meaning that if a company policy is breached, it can easily be tracked back to the person who made that decision.

ABAC is a system that allows users to be granted access based on the roles and access controls of other users, without sharing passwords. Attribute Based Access Control (ABAC) is an access control model based on attributes assigned to subjects and objects.

ABAC empowers you to have confidence that only the right people have access to the right data. Built for the needs of Information Security, it adds accountability to access control.
ABAC is an access control method for specifying the conditions that grant a subject access to an object. ABAC is used for access control by many government agencies and enterprises.


How do I control access?

Access Control is a fundamental element of information security. The ability to control the way in which your information is accessed and by whom is fundamental to an organisation’s data protection strategy.

Controlling access is one of the key tasks of Information Security, and one of the most important. No matter what security measures are in place, all data should be considered unauthorized for release to the public. Any information which might give clues to the identity of the owner or operator of a web server should not be made public.


What is an access control policy?

An access control policy It’s a set of rules that determines who has access to what, and under what circumstances. An access control policy is a strategy for granting or restricting access to information resources to authorized users. These policies are based on a set of rules that define who can access what resource.

Access control policies are commonly governed by a security policy and they keep you informed of all current threats and security vulnerabilities, so you can take appropriate action.


How do I implement access control policies?

How do I implement access control policies? For information security and risk management, layered security is vital. When it comes to web architecture, layered security is an IT best practice for the modern-day enterprise.

Access control is important to ensure that any confidential data cannot be accessed by unauthorized people who gain physical access to a system. The best advice you can give is to implement both the principle of least privilege as well as strong encryption to protect your data.


Why is access control important?

Access control ensures that only those authorized can access information, facilities or physical areas. This is of prime interest to many organizations, as they want to contain the confidential information that they hold and restrict access to only the people who need such information (or in some cases, want such information).

Without it, an entity with even brief access to your network could steal data about your organization or customers, destroy critical systems and assets, deny local and remote users access to those resources or transfer sensitive information outside of the company. Access control helps safeguard individuals against potentially harmful entities in the online environment.
For companies and organizations, information security is critical to survival, without effective security measures in place your data and files may become vulnerable to unwanted access or theft.


What are the advantages and benefits of access control?

The greatest benefactor of access control is security. Whether it’s to restrict employee access to sensitive areas, or prevent unauthorized entry altogether, proper access control can vastly improve your organization’s information security.

An access control system is the software that enables you to grant or deny access to your data. If there’s a breach, it immediately and automatically detects whether or not an unauthorized file is opened and where it was opened from. So if someone tries to steal your work, they won’t get away with it. Your important files are kept safe by protecting them against theft through data


What are the challenges of access control?

What are the challenges of access control? The challenge is that you need to ensure that only the right people have access to your facility. Some challenges of access control includes; protecting data, preventing fraud and safeguarding intellectual property.

Information security is a big challenge, because there are many information system attacks. Some of them are: worm attack, denial-of-service attack, backdoor attack. Some of the most important steps to protect information systems are to make sure that all programs and data are correct and complete.
