One way to collaborate in a team is to achieve shared knowledge together. An example of this is the online activity of “30 days of testing” that The Ministry Of Testing has been putting out to the online community to participate it. My test team has a “Work Group / Special Interest Group” with regards to security testing, so when a 30 day challenge for security testing came up, we scheduled sessions to learn from the topics provided (see below).
As we are testing consultants doing work for our customers, we scheduled 3 sessions – initially for an hour. At the start of the hour we picked 4-5 topics from the list, and worked our way through them in a prioritized order – within the time box of the hour. Come to think of it we might as well have used the Lean Coffee format. As we have team members two places in DK and one place in PH, it was a skype call using screen sharing. After the call I summarized sending out a “link mail” to all in the testing group (DK and PH). Evaluating the sessions we extend our ordinary scheduled WG meetings to make room for collaboratively investigate additional security testing topics.
12 From the list: ZAP, Google Gruyere, threat models, HTTP proxies, posture assessments, tiger boxes, recent hacks (elaborated by Troy Hunt), OWASP top 10, OWASP SQL injections, adding data integrity testing into a test plan, share ideas for security testing internally and externally, discuss security testing with regards to EU GDPR compliance.
7 Not on the list: Naughty Strings form GitHub, Bug Magnet plugin, How real persons names trick IT systems, how to be careful with custom license plates, DDoS attacks, IoT privacy failures, Chaos monkeys/Siamese army and little Bobby Tables:

To sum up, we have learned about: what tools that can make testing easier, where to read about vulnerabilities and and simple exploits, understand how personal data and logins are used and stored, how to pitch security testing based on fear of breaches and safety concerns, testing the requirements for “by design” security.
