One of the advantages of moving call center software to the Cloud is the lower cost of managing your infrastructure. Despite this, it is still vitally important that you do manage the infrastructure. Security holes are always being discovered, and keeping your software up to date and following best practices will help your platform from becoming exploited.
For most of the last decade, Indosoft has preferred a Debian-based server operating system, but has needed to stay with Bash to avoid errors in a third-party configuration tool. Recent news is therefore of concern, so it is a relief that repair of the Shellshock vulnerability on Debian and Ubuntu systems is so straightforward.
As long as one is mindful of security updates and best practices, running call center software in the Cloud can offer benefits to the enterprise. Keeping software updated, setting up firewalls, and closing known vulnerabilities will allow you to focus most of your attention where it should be.
