Preventing Lateral Movement with Discretionary Access Control: A Manager's Guide
Lateral movement is a term that describes when attackers move within a computer system, trying to get access to more parts of it. They do this after they’ve already broken in, hoping to reach valuable information. It's like a digital game of hide and seek, and as a tech manager, it's crucial to put a stop to it. This guide explains how Discretionary Access Control (DAC) can help.
Understanding Discretionary Access Control
What is Discretionary Access Control (DAC)?
Discretionary Access Control is a way to regulate who can access data in a system. The user who owns the data decides who gets in and how much access they have. Imagine it as a key that only the right people can use.
Why is DAC Important?
DAC is important because it keeps sensitive information safe from unauthorized users. By controlling access, you reduce the risk of data breaches and make it harder for attackers to move around unnoticed.
Main Strategies for Using DAC to Prevent Lateral Movement
- Set Clear Permissions
- What: Assign specific permissions to users based on their roles.
- Why: Clear permissions ensure that only the necessary people access each piece of information. This limits the areas attackers can exploit.
- How: Regularly review and update who has access to what parts of the system.
- Monitor User Access
- What: Keep track of who logs into your system and what they do.
- Why: Monitoring helps identify suspicious activities that might indicate an attacker.
- How: Use tools that log user actions and set alerts for unusual behavior.
- Regularly Update Access Controls
- What: Refresh and reassess access controls frequently.
- Why: As team roles change, access needs to be updated to prevent former employees or irrelevant personas from maintaining access.
- How: Schedule regular audits of your access permissions to find and fix potential weak spots.
- Educate Your Team
- What: Train your team on best security practices.
- Why: Well-informed employees are your first line of defense against attacks.
- How: Organize regular workshops to keep everyone updated on the latest security threats and DAC usage.
