Denylisting is a security capability that reduces harmful security attacks by denying access to listed elements.
Let’s Define Denylisting
Denylisting is defined as a basic access control mechanism that allows through all elements except those explicitly mentioned on a “deny” list. Therefore, those items on the list are denied access.
Denylists can be applied at various points in a security architecture i.e. host, web proxy, DNS servers, firewalls, etc. Denylisting examples may include a company preventing a list of software from running on its network, unapproved apps or blocked websites.
In today’s high-risk cyber world, it’s critical to have a complete endpoint security solution that includes allowlisting so that sensitive data is continually protected. Based on strict policies of allowable activities, allowlisting and application control allows for critical system lockdowns in real time that automatically prevent all untrusted files, applications, and processes from executing. With these sophisticated capabilities, companies can:
Stop Attacks by allowing only approved software to run
Automate Software approvals and updates via IT and cloud-driven policies
Prevent Unwanted Change to system configuration at the kernel and user mode levels
Power Device Control and file integrity monitoring and control (FIM/FIC) capabilities
Meet IT Risk and audit controls across major regulatory mandates
