Inner Source

InnerSource takes the lessons learned from developing open source software and applies them to the way companies develop software internally. As developers have become accustomed to working on world class open source software, there is a strong desire to bring those practices back inside the firewall and apply them to software that companies may be reluctant to release. For companies building mostly closed source software, InnerSource can be a great tool to help break down silos, encourage internal collaboration, accelerate new engineer on-boarding, and identify opportunities to contribute software back to the open source world.

vulnerability

A vulnerability /ˌvʌlnərəˈbɪləti/ is a weakness in a system that allows a threat source to compromise its security. It can be a software, hardware, procedural, or human weakness that can be exploited. A vulnerability may be a service running on a server, unpatched applications or operating systems, an unrestricted wireless access point, an open port on a firewall, lax physical security that allows anyone to enter a server room, or unenforced password management on servers and workstations.

Vulnerability Assessment

A vulnerability assessment identifies a wide range of vulnerabilities in the environment. This is commonly carried out through a scanning tool. The idea is to identify any vulnerabilities that potentially could be used to compromise the security of our systems. By contrast, in a penetration test, the security professional exploits one or more vulnerabilities to prove to the customer (or your boss) that a hacker can actually gain access to company resources.
