The not so scary security conference.
In any application security conference, the juciest parts are always the new and interesting ways in which our precious data can be exposed by vulnerabilities in our code, the frameworks on which we’ve built our code, or the infrastructure on which our code runs. Those responsible for delivering software listen intently, asking questions like ‘Do we do that?’, ‘Can that happen to us?’ and more importantly, ‘What will it take to fix that?’. OWASP AppSec AU 2017 provided plenty of interesting tips and tricks for liberating data from vulnerable applications, and fortunately plenty of advice on how to keep the bad guys out.
Now in its second year, OWASP AppSec AU is a passion project run by Julian Berton and Sergi B consisting of two days of workshops followed by a one day mini conference. Running from the 7th to the 9th of September, this year’s event was held on Queen Street, in the heart of the Melbourne CBD.
I attended the mini conference on Saturday as a refresher on my rusty app sec knowledge, to get to know a few people in the Melbourne security community and to check out Troy Hunt’s always entertaining views on the world of security.
To kick things off Daniel Grzelak, head of security at Atlassian, provided an in-depth look into why good hygiene of your AWS accounts is critical to protecting your account from a wide range of enumeration attacks and provided a number of handy scripts to help illustrate his point. Third party integrations, which assume a role within your account, can serve as a backdoor to your account even when that role is read only, as hackers will often find API keys and secrets stored in Cloud Formation scripts and EC2 user data. To prevent detection, a few clever tricks using Lamdba functions were demonstrated, allowing intruders to spawn additional backdoor accounts and mask nefarious behaviour from Cloud Trail logs.
Sam ‘Frenchie’ Stewart, lead infrastructure engineer at CultureAmp gave us a crash course in Zero Trust Networks based on the recent O’Reilly publication. Zero trust networks are a move away from traditional perimeter based networks, where entire segments of a network are trusted, to authorise and authenticate all interactions between actors in a system where policies are provided by a trust engine. Security groups within AWS can in some ways serve as a tool to implement a zero trust network. Insightful talk and an equally impressive beard!
After lunch, Andrew Bienert, security architect at Seek restored our faith in AWS by explaining how Seek ‘wrangle security’ across over 100 AWS accounts. DevSecOps style automated checks, run on Lamdba, continuously running across their accounts help to ensure best practice configuration of AWS resources from a security perspective.
Jen Zajac, lead frontend developer at Catalyst, went into CSP in a bit more depth, discussed client side input validation and the pros and cons of current client side storage mechanisms. In what was my favourite talk of the day, Jen also showed us how the
bug feature in all browsers can be used to implement a very simple phishing attack. Read more about it here.
Troy Hunt was up last with a very entertaining look at what goes on behind the scenes of his highly successful Have I Been Pwned website. If you haven’t yet had the chance to see Troy speak, hunt him down! I think I’ll put my hand up next time he asks the crowd if anyone was involved in the Ashley Madison data breach just to see the response I get.
The day finished up with an Ask Me Anything panel consisting of Julian Berton, Sergi B, Pamel O’Shea and Bec, providing a fun forum to poke fun at recruiters and to hear anecdotes about how those on the panel go about embedding security within the development culture at their respective organisations. Apparently all it takes is snacks!
Sergi and Julian put together an engaging, fun and insightful mini conference that appeals to security professionals, developers and those who are curious about what’s happening in the app sec space. The grassroots nature of the conference made it feel very accessible to newcomers like myself. Great work guys! I might even bring my laptop along next year and have a go at the workshops..
