Re: Rethinking Patching Strategies
@ODA155 ---Thanks for your comments and response. You make some valid and interesting points. Consider this... what if liability could be assign to software vendors who write bad code. I think companies who acquire software through the software supply chain should care about the software they purchase. Why bring in bad software into your environment? I think it's prudent and imperative to work with software vendors to ensure they are taking the necessary steps to build and design secure systems. With the adoption of open-source, the notion of proprietary software is becoming obsolete because all products have some open-source library, component, or module some where in the code base. Thanks again.. good points!!!

Re: I wonder
@Whoopty ... Thanks, I appreciate your comments. I tend to look at software development as software development, whether it's mobile, web, or gaming for that matter. I definitely believe there should be a more assertive focus on secure coding practices, given that perimeter security disappearing right before our eyes with wearable devices and IoT. There is no silver bullet to security, however, reducing the attack surface and ways in which a system can be compromised starts with secure coding and development. Thanks again KevEG

I wonder
I wonder if this sort of strategy, if implemented, will trickle down into game development? There's a real issue in game making at the moment with horrendously buggy products, vulnerabilities, flaws and problems that are coming along with the increase in game complexity and size. Despite years of work, they're releasing as broken messes. 

Do you think a more robust focus on secure practices in the original development would help alleciate problems there like it would with less fun software?

Rethinking Patching Strategies
@Kevin E. Greene...

"It becomes nearly impossible for organizations to patch anywhere near 100% when you take into account zero-day vulnerabilities, manual patching, ineffective patch management solutions, the inability to patch critical systems that can't be taken offline, and other factors that impact the operations of IT system environments from heterogeneous environments "
I know that everyone has different challanges, but in my very humble opinion, that statement is the exact reason(s) that patching is not taken as seriously as it should be.

First a comment about CVE that security admins need to know. In January the MITRE is changing the Syntax, or format of the CVE listings to be able to handle the more than 10,000 vulnerabilities expected to come in a single year, as your opening statement pointed out. So I would deficiently recommend looking into that I would add a link but I don't think that's allowed.

So, I want to comment on your statement one point at a time.
  • It becomes nearly impossible for organizations to patch anywhere near 100%

I've been in IT since 1998 and Information Security since 2003 and from my experience nobody expects to get 100% coverage, most do not even try.


  • when you take into account zero-day vulnerabilities

Zero-Day... this is the unknown, and if you're going to patch anything you most likely should consider patching this, wouldn't you agree?


  • manual patching, ineffective patch management solutions

Still, none of these are an excuse or a reason for not patching. If you're doing manual patching on more than 500 systems (and that's way too many) I recommend looking for a new job because you're setting yourself up for failure and use as a scape goat. As for ineffective solutions, I would recommend a solution where the prime and proven focus is patching and not the 10 other functions that come as bundled "features".


  • the inability to patch critical systems that can't be taken offline

Why can't a system be taken offline? If a system is really that critical then most likely you'll have another as backup because if it's contiunally running and never getting ANY maintenance then it will soon decide on its own to stop working, nothing runs forever. And "can't be taken offline" only means that who ever makes the decisions has decided that the business is more important than what makes the business run and really has not considered what will inevitably will happen.
  • and other factors that impact the operations of IT system environments

Other factors, my favorite subject. Senior IT and management folks who do not want to hear about system downtime, how certain users complain because an update may require a reboot, how AV does not catch all of the malware that they allow onto their machines. Are those the "other factors" you speak of?

Again, in my opinion, there should be no reason why an organization should not be able to patch over 90% of laptops or desktop computers and at least 75% of servers. And that takes into account that on a server you mostly are only patching the OS and maybe an application because I do understand that patching a web server or some DB does require more coordination and support from multiple sources, but it can be done... it has to be.

At the organization level where I sit, I can't be concerned with why large software vendors release bad code... I have enough problems trying to get people to understand that we have to protect our systems and our data and a part of that is patching.


"It should be noted that I'm not advocating abandoning patching strategies. However, I am encouraging organizations to put a greater emphasis on developing better quality software."

For companies that develop their own specialized applications I would definitely agree, and hopefully they'll get the right people to do that and respect the results of an audit or QA assessment before rushing to put something into production.

Nice article!

How Machine Learning, AI & Deep Learning Improve Cybersecurity
Machine intelligence is influencing all aspects of cybersecurity. Organizations are implementing AI-based security to analyze event data using ML models that identify attack patterns and increase automation. Before security teams can take advantage of AI and ML tools, they need to know what is possible.
