As I discussed in Black Hat Preview: Automating Cloud Security Policy Compliance, you can combine Amazon S3 and IAM roles to securely provision configuration files (or any other files) and credentials to Amazon EC2 or VPC instances. Here are the details.

Our last post described how to use Amazon EC2, S3, and IAM as a framework to securely and automatically download security policies and credentials. That’s the infrastructure side of the problem, and this post will show what you need to do to the instance to connect to this infrastructure, grab the credentials, install and configure Chef, and connect to the Chef server. The advantage of this structure is that you don’t need to embed credentials into your machine image, and you can use stock…

How Not to Handle a Malware Outbreak

Dave Lewis · July 9, 2013

Malware is a pervasive problem in enterprises today. It can often be insidious as hell and difficult to ferret out. But sometimes the response to a malware outbreak defies basic common sense. The CIO for the Economic Development Administration (EDA) thought a scorched earth policy was the best approach…

Today on the Microsoft Security Response Center Blog:

Under the policy, developers will have a maximum of 180 days to submit an updated app for security vulnerabilities that are not under active attack and are rated Critical or Important according to the Microsoft Security Response Center rating system. The updated app must be submitted to the store within 180 days of the first report that reproduces the issue. Microsoft reserves the right to take swift action in all cases, which may include…

Today I was mildly snarky on the Security Metrics email list when a few people suggested that instead of talking about cloud computing we should talk about shared infrastructure. In their minds, ‘shared’ = ‘cloud’. I fully acknowledge that I may be misinterpreting their point, but this is a common thread I hear. Worse yet, very frequently when I discuss security risks, other security professionals key in on multitenancy as their biggest concern in cloud computing.

RSA Acquires Aveksa

Adrian Lane · July 9, 2013

EMC has announced the acquisition of Aveksa, one of the burgeoning players in the identity management space. Aveksa will be moved into the RSA security division, and no doubt merged with existing authentication products. From the Aveksa blog:

In our introduction to Continuous Security Monitoring we discussed the rapid advancement of attacks, and why that means you can never “get ahead of the threat”. That means you need to react faster to what’s happening, which requires shortening the window of exposure by embracing extensive security monitoring. We tipped our hats to both PCI Council and the US government for requiring monitoring as a key aspect of their mandates. The US government pushed it a step further by including…

Well, this is embarrassing:

Blowing hash and signing functions so that the underlying code can be changed without the hash and sigs changing is horrifyingly atrocious. This is the code equivalent of impersonating a person with a mask so good nobody, not even the real person themselves, can tell the difference.

Proactive WebAppSec

Earlier this week rsnake blogged about the Top 10 Proactive Web Application Security Measures. He has a very good set of recommendations, a highly recommended read for web application developers and webmasters alike:

Database Denial of Service: Attacks

Adrian Lane · July 3, 2013

Today’s post will discuss database denial of service attacks so later we can consider how to stop them.

From the security researcher’s perspective I cannot help but be impressed by the diversity of database DoS attacks. Many such attacks are pretty dumb – they seem to be written by a person who does not understand SQL, writing horrible queries that are the opposite of efficient. Some exploits are so simple – yet clever – that we are amazed the targeted vulnerability was not found in quality…
