2016-047: Inserting Security into the SDLC, finding Privilege Escalation in poorly configured Linux systems

Just a quick episode this week...

As part of the Brakesec Book Club (join us on our #Slack Channel for more information!) we are discussing Dr. Gary McGraw's book "Software Security: Building Security In" (Amazon Link: https://is.gd/QtHQcM)

We talk about the need to inserting security into your company's #SDLC... but what exactly can be done to enable that? I talk about abuse cases, #risk #analysis, creating test cases, pentesting, and #security #operations are all methods to do so.

Finally, I discovered a blog talking about ways to discover configuration errors on Linux systems that might allow #privilege #escalation to occur. Using these tools as part of your hardening processes could lower the risk of a bad actor gaining elevated privileges on your *unix hosts

2016-046: BlackNurse, Buenoware, ICMP, Atombombing, and PDF converter fails

This week, Mr. Boettcher found himself with an interesting conundrum concerning what happened when he converted a Windows DOCX file to a PDF using a popular #PDF converter software. We discuss what happened, how Software Restriction Policy in Windows kept him safe from a potential malware infection, and about the logging that occurred.

After that, we discuss some recent vulnerabilities, like the BlackNurse Resource Exhaustion vulnerability and how you can protect your infrastructure from a DDoS that can occur from someone sending your firewall 300 packets a second... which anyone can do.

We discuss Robert Graham's recent run-in with a new surveillance camera and how it was pwned in less time than you think. And learn about the 'buenoware' that has been released that 'patches' IoT and embedded devices... But does it do more harm than good, and is it legal?

All that and more this week on Brakeing Down Security Podcast!

2016-045: Aamir Lakhani discusses the dark web, creating a reputation, and is all the content bad?

Mr. Boettcher and I met Mr. Aamir #Lakhani at DerbyCon this year, and immediately intrigued with his work on the Dark Web.

He has assisted with law enforcement investigations, a known member of the dark web, to the point where people with malware or bots will seek him out in an effort to 'legitimize' their work, similar to how being reported on by #blogger/#journalist Brian #Krebs establishes legitimacy for many #carders.

#Aamir sat down and discussed his work, the tools he uses, how he started being a known quantity on the #Dark #Web, the value of your #reputation there, and how quickly people who are there will assist to get rid of 'bad' people, when they themselves are committing crimes... an interesting study in the moral compass of people on the dark web.

We also discuss a recent study that the vast majority of content on the dark web is not illegal content... at least not in the U.S. and most Westernized countries. Finally, we discuss recent shutdown of illegal #Dark #Markets and what that means for the denizens of the #UnderWeb.

2016-044: Chain of Custody, data and evidence integrity

During a Security Incident, or in the course of an investigation, it may become necessary to gather evidence for further use in a possible court case in the future. But if you don't have 4-10,000 dollars USD for fancy forensic software, you'll need to find methods to preserve data, create proper integrity, and have a proper custody list to show who handled the data, how it was collected, etc.

This podcast was not meant to turn you into an expert, but instead to go over the finer points of the process, and even where you should turn to if you need help.

2016-043: BSIMMv7, a teachable moment, and our new Slack Channel!

 

**Brakeing Down Security has a Slack channel now... just go to https://brakesec.signup.team and follow the instructions to have the bot add you to our show's official channel.**

Every year, organizations come out with industry reports that show how well or, more often than not, how poorly we are doing.

We always even reviewing the BSIMM report, because it's an unvarnished, and a good measure of a good number of industry verticals, like finance, manufacturing, cloud, and even companies that make IoT devices.

Join Mr. Boettcher and I this week as we go over the findings of the report, discuss what got better, what still sucks, and what shouldn't we fault companies for not having.

We also have a teachable moment when I discuss a security paux fas that happened to me (Bryan) recently regarding an email account and my Skype. 2 factor authentication is your friend, and if it's available, use it.

Mr. Boettcher discusses some recent malware that has reared it's ugly head, and how to detect it.
