Allowlisting Discretionary Access Control: A Simple Guide for Tech Managers
Tech managers who want to protect their networks often explore different methods to control who can access their systems. Two common techniques are IP allowlisting and Discretionary Access Control (DAC). Let’s break down what these methods involve and how they offer security.
What is IP Allowlisting?
IP allowlisting involves specifying which IP addresses can access your network or systems. Think of it as creating a VIP list for your digital assets. Only those on the list can get in. This ensures that only trusted IPs—like your office network or known offsite locations—have access, blocking unauthorized, potentially harmful visits.
Why It Matters: By limiting access to pre-approved IP addresses, you reduce the risk of cyber-attacks. Hackers often change IP addresses to attempt unauthorized breaches, but with allowlisting, these attempts are thwarted since their IPs won't be on the list.
How to Use It: Implementing IP allowlisting is a straightforward process. You would create a list of safe IP addresses you trust using your network’s firewall settings. It's essential to keep this list updated as your team grows or locations change.
Understanding Discretionary Access Control (DAC)
Discretionary Access Control is a security strategy where resource owners determine who can access their data. Imagine your computer files with custom gates that you control. You decide who can enter, view, edit, or manage those files.
Why It Matters: DAC is flexible, granting data owners the power to specify access rules. It allows for dynamic adjustments, so when roles change within your team, you can swiftly adjust permissions without overhauling your security layout.
How to Use It: To apply DAC, define who the data owners are within your organization and give them permission to manage access. They can then set rules for who views or modifies specific files, ensuring sensitive information remains secure.
Combining IP Allowlisting with DAC
Utilizing both IP allowlisting and Discretionary Access Control gives a strong security stance. Allowlisting limits entry points to your network, while DAC manages who does what once they're inside. Together, they build robust, overlapping defenses.
Why It Matters: When these security methods work hand-in-hand, they guard against unauthorized access both from getting into the network and while inside. This dual approach ensures a comprehensive defense against potential threats.
How to Use It: Begin with a secure IP allowlist to filter access at the network level. Next, empower your data owners with DAC configurations to ensure once inside, only authorized users can interact with specific data. Regularly review and adapt these settings to remain in line with your company's needs.
