Database Security Fundamentals: Database Access Methods

By Adrian Lane
It’s tough to talk about securing database access methods in a series designed to cover database security basics, because the access attacks are not basic. They tend to exploit either communications media or external functions – taking advantage of subtleties or logic flaws – capitalizing on trust relationships, or just being very unconventional and thus hard to anticipate. Still, some of the attacks are right through an open front door, like forgetting to set a TNS Listener password on Oracle. I will cover the basics here, as well as a few more involved things which can be addressed with a few

The Death of Product Reviews

By Mike Rothman
As a security practitioner, it has always been difficult to select the ‘right’ product. You (kind of) know what problem needs to be solved, yet you often don’t have any idea how any particular product will work and scale in your production environment. Sometimes it is difficult to identify the right vendors to bring in for an evaluation. Even when you do, no number of vendor meetings, SE demos, or proof of concept installations can tell you what you need to know. So it’s really about assembling a number of data points and trying to do your homework

Choose Your Own Whitepaper Adventure (and Upcoming Papers)

We are in the process of finalizing some research planning for the next few months, so I want to see if there are any requests for research out there. First, here are some papers we anticipate completing over the next 3 months: Understanding and Selecting a Database Encryption or Tokenization Solution Understanding and Selecting a Database Assessment Solution Project Quant for Database Security Quick Wins with DLP Pragmatic Data Security Network Security Fundamentals Endpoint Security Fundamentals Understanding and Selecting a SIEM/Log Management Product Understanding and Implementing Network Segregation Data Security for the Cloud Some of these are sponsored, some aren’

Incite 2/10/2010: Comfortably Numb

By Mike Rothman
You may not know it, but lots of folks you know are zombies. It seems that life has beaten them down, and miraculously two weeks later they don’t say ‘hi’ – they just give you a blank stare and grin as the spittle drips out of the corners of their mouths. Yup, a sure sign they’ve been to see Dr. Feelgood, who heard for an hour how hard their lives are, and as opposed to helping to deal with the pain, they got their friends Prozac, Lexapro, and Zoloft numb it. These billion dollar drugs build on the premise

Counterpoint: Correlation Is Useful, but Threat Assessment Is Fundamental

By Adrian Lane
So it’s probably apparent that Mike and I have slightly different opinions on some security topics, such as Monitoring Everything (or not). But sometimes we have exactly the same viewpoint, for slightly different reasons. Correlation is one of these later examples. I don’t like correlation. Actually, I am bitter that I have to do correlation at all. But we have to do it because log files suck. Please, I don’t want log management and SIEM vendors to get all huffy with that statement: it’s not your fault. All data sources for forensic information pretty much lack

Network Security Fundamentals: Correlation

By Mike Rothman
In the last Network Security Fundamentals post, we talked about monitoring (almost) everything and how that drives a data/log aggregation and collection strategy. It’s great to have all that cool data, but now what? That brings up the ‘C word’ of security: correlation. Most security professionals have tried and failed to get sufficient value from correlation relative to the cost, complexity, and effort involved in deploying the technology. Understandably, trepidation and skepticism surface any time you bring up the idea of real-time analysis of security data. As usual, it comes back to a problem with management of expectations.

Misconceptions of a DMZ

By David J. Meier
A recent post tying segmented web browsing to DMZs by Daniel Miessler got me thinking more about the network segmentation that is lacking in most organizations. The concept behind that article is to establish a browser network in a DMZ, wherein nothing is trusted. When a user wants to browse the web, the article implies that the user fires up a connection into the browser network for some kind of proxy out onto the big, bad Internet. The transport for this connection is left to the user’s imagination, but it’s easy to envision something along the lines of

Litchfield Discloses Oracle 0-Day at Black Hat

By Adrian Lane
During Black Hat last week, David Litchfield disclosed that he had discovered an 0-day in Oracle 11G which allowed him to acquire administrative level credentials. Until today, I was unaware that the attack details were made available as well, meaning anyone can bounce the exploit off your database server to see if it is vulnerable. From the NetworkWorld article, the vulnerability is … … the way Java has been implemented in Oracle 11g Release 2, there’s an overly permissive default grant that makes it possible for a low privileged user to grant himself arbitrary permissions. In a demo of Oracle 11g Enterprise

Counterpoint: Admin Rights Don’t Matter the Way You Think They Do

By Rich
Update – Based on feedback, I failed to distinguish that I’m referring to normal users running as admin. Sysadmins and domain admins definitely shouldn’t be running with their admin privileges except for when they need them. As you can read in the comments, that’s a huge risk. When I was reviewing Mike’s FireStarter on yanking admin rights from users, it got me thinking on whether admin rights really matter at all. Yes, I realize this is a staple of security dogma, but I think the value of admin rights is completely overblown due to two reasons: There

Rock Beats Scissors, and People Beat Process

By Adrian Lane
My mentors in engineering management used to define their job as managing people, process, and technology. Those three realms, and how they interact, are a handy way to conceptualize organizational management responsibilities. We use process to frame how we want people to behave – trying to promote productivity, foster inter-group cooperation, and minimize mistakes. The people are the important part of the equation, and the process is there to help make them better as a group. How you set up process directly impacts productivity, arranges priority, and creates or reduces friction. Subtle adjustments to process are needed to account for individuals,
