The most magnificent thing about Vulnerabilities and who is behind the magic

What I like the most about software vulnerabilities is how "vulnerability", as a quality of a real object and the computer program is real, literally appears from nothing. Let's say we have a fully updated server. We turn it off, lock it in a safe and forget about it for half a year. Six months...

What I expect from IT Asset Inventory

The main problem of vulnerability management, in my opinion, is that it is not always clear whether we know about ALL network hosts existing in our infrastructure or not. So, not the actual process of scanning and the detection of vulnerabilities, but the lack of knowledge what we should scan...

Starting/stopping Amazon EC2 instances using CLI and Python SDK

Vulnerability subscriptions in terms of business

The question is: do we really need an employee in organization that deals with vulnerabilities in infrastructure on a full-time basis?

First steps with Docker: installation in CentOS 7, vulnerability assessment, interactive mode and saving changes
