What Are Access Control Policies?

Last Updated on January 17, 2025 by Deepanshu Sharma

Unauthorized access, whether deliberate or inadvertent, can have catastrophic consequences, such as data breaches, financial losses, and reputational damage. Since the majority of business operations depend on vast volumes of data and information, issues with data security and access are inevitable. Access control policies help to mitigate these issues by limiting excessive access.

The term “access control policy” refers to the collection of guidelines, directives, and limitations that outline who has access to your data, to what extent, and when. All individuals who have access to data within the company, including stakeholders, customers, and data producers, must abide by these rules. These policies, procedures, and directives control how IT assets and resources are used. The policy also specifies what the authorized user is permitted to do once access has been granted.

The provision of a secure environment is the primary objective of access control rules. These rules must match the objectives of the company. These are the justifications for the necessity of access control rules.

1. Improved Security: Access control is mostly used to improve security. Unauthorized access attempts are not just denied with a properly built access control system. The increased security that access control offers is essential in industries like healthcare and government where a lot of private data is handled. Access control allows restricted entry to authorized individuals only, preventing unauthorized access and potential security breaches.
2. Operational Efficiency: The efficiency of the operation is increased by the access control system. By enabling the authorized individual to enter the locations they require without needless delays, they help increase operational efficiency. In the event that an alarm receives text messages, access can be granted and permissions can be managed with a software link to preserve operation efficiency.
3. Security Risks: One of the purposes of access control policies is to reduce security threats by adding an extra degree of security. There are a few techniques to reduce illegal entrance by implementing security concerns, such as biometric authentication and mobile credentials that only allow authorized persons to access data.
4. Real-Time Monitoring: Through access control policies, entries and current events can be tracked and monitored in real time. By monitoring, it would be able to keep track of who has gone where and when. By monitoring your access control system, you can protect equipment, data centers, and sensitive information. When access is restricted to those who are allowed, the likelihood of theft, vandalism, or unlawful use is reduced.

A few instances of data access control policies are listed below.

1. 1. All teams will have access to important information, but only under disguised circumstances. It is possible to grant access to the decrypted data to particular teams.
   2. Distinctly sensitive material is stored on various platforms, and only a limited number of people will have access to it depending on the situation. The rest of the data is kept secure.
   3. Users will only be able to access confidential information from the office and the IP address of office systems thanks to control policies.

   Types of Access Control Policies

   1. Rule-Based Access Control: The usage of rule-based access control (RUBAC) with networking equipment is widespread. RuBAC regulations are universal; they are applicable to every subject in the same way. They are compatible with routers and firewalls, among other networking devices. The majority of the time, RuBAC policies operate on an implicit refuse basis, allowing access only when specifically instructed to do so by the rules. Moreover, the zero-trust security architecture is consistent with rule-based access control policies.
   2. Mandatory Access Control: Mandatory Access Control only provides information to those who have a “need to know” and rigorously upholds the Zero Trust paradigm of security. In highly regulated enterprises and the government, mandatory access control, or MAC, is frequent. The system administrator sets up access rules by giving subjects and objects security permissions in accordance with mandated information access control regulations. Only items that fall within their specified hierarchy are accessible to subjects. A MAC’s structure fits in with extremely secure companies where a subject’s clearance level determines their level of access.
   3. Role-Based Access Control: Users are granted permissions and privileges by RBAC (Role-Based Access Control) systems according to their jobs and responsibilities. For instance, a software engineer might be able to access the staging virtual machines, the CI/CD tool, and the source code repository. Conversely, a production engineer can be the only one with access to the production virtual machines. Roles and user groups are used in role-based access control (RBAC) to classify access controls. System administrators can use RBAC to set up access permissions to apply at the role level and assign roles to subjects. Permission to use a resource will be automatically granted or denied based on the role of the subject. RBAC can produce a successful access management policy in a static setting with few shift changes.
   4. Discretionary Access Control: DAC is a versatile model type that gives resource owners control over who can access their assets. Under Discretionary Access Control, the data owner decides on policy. Who has access to the data and to what degree is decided by the business owner. Within a DAC system, the file owner can specify their own sharing parameters and access permissions for any receiver they wish. Usually, the file developer has total control over these settings and can change them whenever they’d like. Generally speaking, most DAC systems allow an administrator to change a user’s permissions.

   How Lepide Helps In Implementing Access Control Policies

   The Lepide Data Security Platform enables IT teams to spot and remediate users with excessive permissions, so that organizations can adhere to the principle of least privilege. Lepide analyzes the permissions of your users and determines when permissions are “excessive” based on user behavior. Lepide can then automatically remediate based on policies to limit your risk.
