Preventing Lateral Movement with Discretionary Access Control: A Guide for Tech Managers

Keeping your organization’s data secure is a big responsibility, especially for technology managers. One way to protect sensitive information and systems is by stopping lateral movement in your network. Lateral movement is when an attacker moves through your network after getting in. This blog post will explore how you can use Discretionary Access Control (DAC) to prevent lateral movement and enhance your organization's security.

What is Discretionary Access Control?

Discretionary Access Control (DAC) is a type of access control where the owner of the information decides who can access it. This control method gives users the power to decide permissions, like who can read or edit certain files. DAC is common because it’s flexible and easy to manage, which makes it a popular choice among tech managers.

Why Does Lateral Movement Matter?

When attackers gain access to your network, their next goal is often to move laterally. This means they want to explore other parts of the network and find valuable information. Lateral movement can lead to data breaches or even full control of your systems. Stopping this movement is crucial to keeping your data safe and your systems secure.

How Can DAC Prevent Lateral Movement?

1. Limit User Permissions: With DAC, users can only access data that the owner has given them permission to use. By controlling who can view or change files, you limit where attackers can go if they gain entrance through one user's account.
2. Enhance User Accountability: DAC records who accesses what information and when. This activity log means you can track suspicious actions and notice unusual behavior quickly.
3. Enable Timely Revocation: If someone leaves your company or their role changes, DAC allows you to quickly adjust or revoke their access. This timely change helps cut off potential lateral movement paths.
4. Use Strong Policies: Make sure all users understand which permissions they should grant and to whom. Strong policies reduce the risk of excessive permissions, minimizing potential routes attackers might take within your network.

Enhancing Network Security with DAC

Implementing DAC effectively can significantly reduce the chance of lateral movement. Here are some steps tech managers can take to integrate DAC into their security strategy:

• Review access permissions regularly and adjust them according to current roles and needs.
• Educate employees about the importance of only granting necessary permissions.
• Monitor access logs to swiftly detect and address unauthorized activity.
