User Access Control
What is User Access Control (UAC)
Defining User Access Control: Secure Your Computer Effectively
User access control (UAC) is a reliable security feature that regulates user actions in a computing environment by asking for permission from authorized users or verifying unauthorized users’ credibility. It is responsible for controlling access to data, apps, and other resources in the computer system. Only qualified users can open the system, use UAC, and access the resources in the system as per their requirements.
UAC in publicly listed companies ensures that only entrusted users with proper credentials can access or modify sensitive financial data, protecting the organization’s assets.
How UAC Works : A Step-by-Step Process Explained
To protect the operating system in any computer from any unauthorized changes and malpractices, a security layer of user access control is important. With the UAC feature, every app inside the operating system asks for permission from an authorized user when it is opened. Here is a breakdown of the steps of how UAC works:
Step 1
Any user who provides verified details—such as personal information, name, purpose of using the computing device, and valid ID proof—becomes an approved user.
Step 2
The UAC then verifies each detail related to the user’s identity.
Step 3
User credentials, including passwords, security tokens, and biometric scans, are created.
Step 4
When another user attempts to access the system, they must request permission.
Step 5
The UAC sends a notification to the authorized user, allowing them to approve or reject the access request.
Understanding the Different Types of UAC Prompts
When a user tries to perform an action that requires administrator privileges, User Access Control prompts appear. There are four types of prompts, including:
Consent prompt
Consent prompt appears when the user attempts to perform a task using an application or system signed by a trusted publisher, such as Microsoft. A consent pop-up appears, and the user must click “Yes” to grant access and proceed with the action.
Credential prompt
The credential prompt appears when the user tries to perform an action using an application or system. This action is performed unsigned by a trusted third party or has undergone modifications since its original signing. To proceed, the user must enter the required password or select an administrator account to confirm access.
Secure desktop prompt
This critical UAC prompt appears when a user attempts high-risk actions, such as changing UAC settings or running unrecognized files. It opens in a separate, secure desktop view isolated from other applications and processes. To proceed, the user must provide a password or select an administrator account, ensuring additional protection against unauthorized access.
Elevation prompt
This prompt appears when performing an action that requires elevated permissions or upgrades. Unlike the secure desktop prompt, it appears directly on the same desktop as the application or process. To proceed, the user must enter a password or select a suitable administrator account.
Why UAC is Important
The importance of UAC lies in its ability to safeguard computer systems in an increasingly data-driven digital age. With growing concerns around data security, implementing a robust user access control feature is crucial. By controlling or limiting user actions, UAC protects systems from unauthorized changes that could impact stability, performance, or security.
Top-tier UAC solutions, provided by reliable partners like SecurEnds, help prevent malware and other threats that can compromise an entire computing infrastructure. Additionally, UAC protects confidential data from theft or misuse, ensuring
UAC also facilitates the management of multiple user accounts within a network by offering configurable control levels and access permissions. This reduces the risk of intentional or accidental changes to data or system settings, contributing to a more secure and stable environment. sensitive information remains secure.
User Access Review for AWS
The process of UAR, or User Access Review, is a useful way to protect sensitive data from being misused, modified, or stolen by periodically reviewing access rights for all user accounts. In an organization, employees and third parties might hold access to different user accounts under a computing system. So, their access is reviewed in the UAR process.
However, AWS accounts can be used by four different types of users- a root user, an IAM user, a user in the IAM Identity Center, and a federated identity. A proficient user access review for AWS helps manage the four different user account types efficiently. Being integrated with the AWS account, UAR for AWS creates a secure space to use and nurture data.
External access findings
These findings denote that resources of an AWS account have been shared with an external entity, such as an IAM user, a federated user, or any anonymous user, that is not within the primary user’s trust zone.

Validating Policies against AWS Best Practices
To ensure a secure AWS infrastructure without setbacks, it is crucial to validate policies against AWS best practices before attaching any user access review framework to an entity. These policy validation checks include assessing security warnings, identifying errors, and providing suggestions for improvement.
Various types of policies come into play here, including identity policies, resource policies, and service control policies (SCPs). With a trusted SaaS partner like SecurEnds, validating all these policies against AWS best practices becomes seamless and hassle-free, ensuring robust and compliant cloud security.
Validating Policies against Your Specified Security Standards
Organizations and individuals can validate policies against their specific security standards before integrating the user access review process into the system. Custom policy checks may include verifying public access and ensuring compliance with reference policies, if applicable. While offering UAR across both cloud and on-premises applications, SecurEnds efficiently validates user action review policies against specified security standards.
SecurEnds identifies and addresses gaps in your computing network with an efficient and secure user access control process. With accurate user access reviews, regulatory compliance, and proactive automation features, SecurEnds’ User Access Control solution is essential for every organization.
