Promote a secure IBM Lotus Notes environment by implementing execution control lists (ECLs) that give permissions to execute actions on the Notes client only to the appropriate entities. Find out the two types of ECLs that administrators must learn to control as well as the entities that have default control over active content. Learn how and why to use functional accounts to sign agents or actions that cause active content on the Notes client.


Execution control lists (ECLs) are the superstars of IBM Lotuotes client security. When configured correctly, ECLs prevent unauthorized changes from being made to a workstation configuration and to user data.
Yet in most domains, ECLs are configured in a way that scares users into making bad security decisions. As you’ll see in a moment, those decisions could leave your Notes clients wide open to attacks by malicious programmers, viruses, and Trojan horse software that claims to be nice but actually wants to ruin your day.
I’ll explain how ECLs protect Notes users and their data. I’ll also show you how default ECLs should be modified to achieve a “best practice” state.
