- Apple threats: the number of people using Macs is growing very fast. It is starting to become something attractive for botnet herders, specially because almost all Mac users don't have anti-malware software installed nor have the habit of worrying about it, so it's easy to mantain the bots installed. If it was in the past I would think about a big worm coming, but cybercrime is reality now and those guys know when an opportunity like this arises.
- Blended/Hybrid Threats: We are seeing this already, like this malware that exploits SQL Injection and an IE vulnerability. I believe we will see a lot of threats using multiple attack vectors, maybe even from different platforms and technologies. Vulnerabilities than can be used to redirect traffic from multiple users (like Dan Kaminsky's DNS bug) will be used to force people to access infected content, that will trigger other infection mechanisms. Worms will be able to disseminate to a higher number of hosts without generating suspect spikes on charts, as the malware code will randomly choose between several infection methods to spread itself. Expect some huge botnets being found as a result.
- At least one "cloud computing" security incident: Ok, not that hard to say that, but I'll try to be a little more specific in the details :-), there will be a discussion about what was compromised (infrastructure? application? vendor? client?) and people will start discussing how to conduct forensics on those new conditions.
- Virtualization nightmare: A vulnerability will be found in a virtualization platform or in a virtualization-aware product, enabling attacks from one guest OS to another (or even reaching a Guest OS and triggering the exploit on another). It would be extremely fun to watch those "the cat is on the roof" discussions. A new wave of miraculous products will be released to solve the issue from that specific kind of attack. Your VM infrastructure will look like a Christmas Tree and the operation cost of a virtualized environment will not be what was expected anymore.

- Logon scripts with clear text passwords (noooo!!!!!!!!!!)
- Scripts from SMS or other central management tool with clear text passwords (believe me, the users will found that!)
- That-same-very-secret-password-that-only-those-ten-guys-know-about-for-all-boxes mistake (yes, I mentioned that before. Just in case)
- Different passwords generate by a "security by obscurity" algorithm that uses the name of the workstation as input. Hey, if it's a bad idea on encryption why would it be a good idea for passwords?

- "User: This is an area I intend to talk about in much greater depth later on. Basically, right now we rely on static authentication (a single set of credentials to provide access) and I think we need to move more towards adaptive authentication (where we provide an authentication rating based on how strongly we trust that user at that time in that situation, and can thus then adjust the kinds of allowed transactions). This actually exists today- for example, my bank uses a username/password to let me in, but then requires an additional credential for transactions vs. basic access.
- Transaction: As with user, this is an area we’ve underexplored in traditional applications, but I think will be incredibly valuable in cloud services. We build something called adaptive authorization into our applications and enforce more controls around approving transactions. For example, if a user with a low authentication rating tries to transfer a large sum out of their bank account, a text message with a code will be send to their cell phone with a code. If they have a higher authentication rating, the value amount before that back channel is required goes up. We build policies on a transaction basis, linking in environmental, user, and situational measurements to approve or deny transactions. This is program logic, not something you can add on."

John Pescatore is right when he says that talking about less regulation at this time seems to be not aligned with the current crysis, but the article he is pointing to is very precise on saying that the costs from SOX are pretty high and, as we could see, it wasn't able to prevent cases like Bear Sterns, Lehman Bros., AIG and Merrill Lynch. Accountants are as creative as lawyers, they will always look for breaches in the controls (laws) to do their magic.
SOX brought a lot of money to Information Security, but it also brought some directed focus on some controls that are not always the most required for all organizations. It would be nice to see a review of the law, verifying its results and actual costs.
A lot of noise about a new research that "cracked" WPA was made this week. Well, there are more details about it today, and they clearly show that the WPA sky is not falling.
There is a very good abstract of what is happening on the article above:
"To describe the attack succinctly, it's a method of decrypting and arbitrarily and successfully re-encrypting and re-injecting short packets on networks that have devices using TKIP. That's a very critical distinction; this is a serious attack, and the first real flaw in TKIP that's been found and exploited. But it's still a subset of a true key crack."
So, it's not the final attack against WPA protected networks, but it is a very important building block for more elaborate attacks. I can see that in a near future we will see more serious stuff being done using this as a starting point. Keep your ears open.

- Mandate the tools (e.g. "must use a firewall") - and risk "checklist mentality", resulting in BOTH insecurity and "false sense" of security.
- Mandate the results (e.g. "must be secure") - and risk people saying "eh, but I dunno how" - and then not acting at all, again leading to insecurity.
solution to this? I personally would take the pill #1 over pill #2 (and
that is why I like PCI that much), but with some pause to think, for sure."Actually, I believe it may be possible to reach an intermediate alternative. By defining the rules and standards for Risk assessment and management we could set the standards on defining acceptable risk levels instead of saying "must be secure", and without the need to go as deep as "must use a firewall". Of course that this approach would cause several questions about how to achieve compliance, but it would give more freedom to organizations about how to approach the risks and avoid "checklist mentality". The problem with risk management based compliance is that the organization can manipulate its risk assessments and downplay stuff that should be identified as "high risks". If the risk equation, impact and probability levels are standardized, however, it would be easy to compare apples to apples and say things like "risks above level X must be mitigated until level Y".Even by taking that approach we would still have to deal with the control efficiency problem. Like the firewall that Anton mentioned, there are several controls (probably most of them) that the way that they were implemented and how they are managed are even more important than the control itself. Maybe the best way to solve that is defining appropriate ways to deploy and maintain each proposed control. Ok, we could go into a very deep (and inefficient) level of details by doing that. Seems to be a catch 22 situation. Personally, I don't know who is worse to point where the bar should be placed: auditors or standard writers. I don't trust both :-)

I'm testing Zoundry Raven calling the XML-RPC interface of Wordpress on a SSL URL. It's maybe an alternative to secure posting, as I can use the "shared certificate" URL for this, what can't be done with the regular wp-admin Wordpress interface. I just need to check if this thing doesn't "escape" from the specified URL to do other stuff.

- Can you promptly identify someone guessing passwords for administrative accounts on all your servers?
- Can you say for sure that there are no weak passwords for all administrative accounts on all your servers?
- Can you say for sure that you don't have a user/password on a test box that also exists on a production server?
- Can you say for sure that there are no shared folders on your servers with sensitive information and weak permissions settings?
- Do you know who knows the password for (and use) the root or Administrator account?

- False positives in correlation rules
- Burden on the IS organization by requiring full-time monitoring
- A taxing incident-response process
- An inability to monitor events at rates greater than 10.000 events per second
- High cost of maintaining and build new adapters
- Complexity of modeling environment

"With a goal of getting IT professionals to use standard terminology and eliminate ambiguity in expressing important risk-management concepts, the Open Group is finalizing a 50-page compendium of "risk-management and analysis taxonomy."The Open Group Security Forum's risk taxonomy of about 100 expressions will not only address seemingly simple words such as threat, vulnerability and risk, but less common terms such as control strength."I was thinking, why these guys are doing it when there are stuff like ISO Guide 73, ISO27005 and ISO27000 published or in their way to be published?

Writing this while waiting to board my return flight to Sao Paulo. Itâ€™s good to write after a few hours far from the conference, as it gives me a better view of what really impressed me most. I agree with other bloggers that mentioned the lack of innovation this year. However, it was expected.
I think I can mention some highlights. Black Ops, Sins of Our Fathers, Avoiding the â€œSecurity groundhog dayâ€, the DLP Panel, Ajax Security were very good in terms of presentation and discussion, but honestly, nothing new from them.
The best sessions for me were Bruce Schneierâ€™s and Malcolm Gladwellâ€™s. Both talked about human perception and the way that we think. Schneier has already published some things about it, especially about the way thaty we perceive Risk. Gladwell presentation was very interesting even if it wasnâ€™t related to security at all. He talked about decision making, but not common decisions, but those made unconsciously. I think there are lots of situations in security that can benefit from his theories. The way that we assemble and conduct security monitoring centers, for instance, can be radically changed. By reading his book (â€œBlink: The Power of Thinking Without Thinking
The exposition was kind of sad. Tons of â€œappliancesâ€ providing solutions to problems defined by the vendors themselves. Lots of vendors talking about how their products provide very nice reports, but what about detection, prevention? Can all the problems in security be solved by a nice report with some pie charts?
The networking aspect, by the other side, was terrific. I met lots of people who write very good blogs, people that I found that are reading mine. I hope to be able to attend to the conference the next years to maintain all those contacts. Thumbs up for Martin McKeay, Jennifer Leggio and Alan Shimmel for organizing the bloggers meetup. It was very good and an extraordinary opportunity to chat with people that I respect a lot. Thanks!
