What Are Time Based Access Controls? How To Implement Them?

In the dynamic realm of digital security, there's a growing demand for precise and adaptable access controls. That's where time based access controls emerge as a strategic response to modern organizations' intricate requirements. In this guide, we'll understand what are time based access controls, their types, importance, benefits, and how to implement them effectively.

Let's begin our exploration by first understanding what exactly time based access controls mean.

What Are Time Based Access Controls?

Time based access controls are security measures that are designed to restrict/limit access to resources based on specific time criteria. These controls enable organizations to establish and enforce access permissions by considering temporal timeframe rules, such as particular hours of the day, specific days of the week, or designated dates.

Furthermore, by implementing time-based access controls, the organization's IT teams can set rules to grant or revoke access from user groups during specified time intervals. This approach ensures that access to sensitive information or crucial systems is only authorized when necessary, minimizing the risk of unauthorized entry outside predefined time frames.

For instance, an organization can use time based access controls to manage employee access to secure data and information. These access control rules can be set to grant users access to an app for a defined duration, such as 1 hour, 12 hours, 1 day, or 1 week. This way, your organization's IT team can ensure employees can only access sensitive data, like customer info or financial details, during certain times set by the company.

However, you also need to familiarize yourself with different types of time based access controls.

3 Types Of Time Based Access Control

Time based access controls are classified into three distinct types. This categorization will help you understand which type of time based access control to implement to meet your access management control needs:

• Type 1# Absolute Time based Access

Absolute time based access controls are established with specific start and end dates or times. This type of access control is well-suited for situations where network resources are needed only during a particular period.

For instance, organizations might implement absolute time based access controls to allow their employees access to the internet solely during working hours. This ensures that valuable resources are not accessible to unauthorized users outside the designated times.

• Type 2# Periodic Time Based Access

Periodic time based access controls enable the creation of rules based on recurring schedules, such as daily, weekly, or monthly patterns. These controls are typically used when a user requires periodic but scheduled access to network resources.

For example, an organization can use periodic time based access controls to provide contractors with VPN remote connectivity every Friday from 6 PM to 10 PM.

• Type 3# Recurring Time Based Access

Recurring time based access controls differ slightly from periodic time based access since they are created using intervals rather than exact dates or times. They offer more flexibility than other access control types as you can set up rules/criteria based on days or weeks from specific events like account creation or password resets.

Furthermore, recurring time based access controls are a great solution for scenarios where users need temporary access to network resources regularly, such as granting VPN remote connectivity to remote workers for 7 consecutive days after they return from vacation.

Now that you are familiar with what time based access controls are and their types, let’s understand why it's important.

Why Are Time Based Access Controls Important?

Time based access controls play a crucial role in managing access within an organization. It allows your IT team to have complete control over when your employees can access the organization's resources during a specific time frame. For instance, if an organization aims to regulate internet access for employees on weekdays or limit server access during specific hours on weekends, time based access control can be used to tailor access to the internet or servers as needed.

This enhances security by reducing exposure to potential threats during inactive hours and contributes to the judicious use of network resources. Time based access controls foster a more secure and optimized network environment by reserving internet bandwidth for work-related tasks during business hours.

In simpler terms, time based access control is important because it enables precise control over granting, restricting, or revoking access within specified time frames. This user access control helps enhance authority (control) and minimizes the likelihood of a security breach.

However, that's not all, time based access control has several advantages. Let's explore a few of them.

Benefits Of Time Based Access Controls for Enterprises

Here are some of the notable benefits of time based access controls:

• Enhanced Security:

Time based access control contributes to improved security by enabling organizations to regulate traffic on a schedule. By allowing or blocking traffic during specific timeframes, such as outside working hours, your IT team can minimize exposure to potential threats, enhancing overall cybersecurity.

• Optimized Bandwidth Management:

Through time based IT access control, your IT team can effectively manage bandwidth by restricting certain types of traffic during peak hours. This approach prioritizes critical applications over non-essential ones, ensuring that essential functions receive optimal bandwidth utilization and reducing the risk of congestion during high-demand periods.

• Streamlined Configuration Process:

Leveraging time based access controls with pre-existing infrastructure provides a more straightforward configuration process. Instead of investing in new solutions for traffic management, organizations can optimize their existing setup. This not only simplifies the overall configuration process but also ensures maximum security and performance without the need for additional, complex implementations.

After going through time based access controls importance and benefits, now you may be willing to implement it in your organization. But how do you implement time based access control? Here’s how.

But how to ensure data safety after this implementation process? Well, you can implement a time based security model. What is that? How does it work?

Time-Based Security Model: A Security Framework To Ensure Data Integrity

A time-based security model enables a company to evaluate whether they have effective measures in place for detecting a breach or not. It implements a system to fix the issue faster than the time it would take for a hacker to infiltrate the system.

Here's a formula that is used in a time-based security model.

Time Based Security Model: P (penetration by hacker) > D (detection by company) + C (correction by company)

If the time taken for a hacker to breach (\"P\") the system exceeds the combined time for the company to detect (\"D\") and correct (\"C\") the issue, the hacker's attempt will be unsuccessful.

For example, a hacker takes 25 minutes to infiltrate the system. On the company's end, it takes 5 minutes to detect the breach and 12 minutes to rectify the system to thwart the hack. Applying the formula, the hacker requires 25 minutes for penetration, while the company takes only 17 minutes to detect and correct the system. Therefore, according to the time based security model, the company can effectively prevent hackers from infiltrating the system.

Now, let's understand how to maintain a time based access control policy.

How To Maintain Time Based Access Control Policy?

Maintaining a time based access control policy includes certain key steps to ensure its effectiveness and relevance over time. Here's a guide on how to maintain such a policy:
