Definition
Allowlisting is a security process that permits only users in a pre-approved list to access a device, network, or system. This is like creating a VIP list that blocks unauthorized parties from accessing your network or device.
Allowlisting vs. Blocklisting
Allowlisting is safer than blocklisting because it imposes stricter rules. However, blocklisting allows everyone to access your device or network except the ones on the list.
Application of Allowlisting
- Network access control: Allowlisting can restrict access to a network, allowing only the pre-approved users and devices. This protects sensitive data from unauthorized access.
- Application control: Allowlisting can restrict the configuration and installation of applications to prevent malware infection.
- Website filtering: Allowlisting can prevent users from accessing unapproved websites. Organizations or parents can use it to stop employees from accessing non-work-related or inappropriate content.
- Email filtering: Allowlisting can stop incoming email messages based on their sender to prevent email-based scams like phishing.
- Device access control: Allowlisting can limit access to specific devices, like printers and USB drives, to prevent unauthorized access or data theft.
Benefits of Allowlisting
- Streamlined IT operations: Allowlisting can enable security experts to manage and monitor network activities easily, thus improving the efficiency of IT operations.
- Compliance and audit readiness: Allowlisting helps companies comply with existing laws and regulations governing IT operations, as they can prove their proactive measures to prevent unauthorized access and potential breaches.
- Reduced attack surface: Allowlisting helps to minimize a firm’s attack surface by eliminating potential entry points for cybercriminals.
