- One Exploit Should Not Ruin Your Day - This post by Dino Dai Zovi re-itterates, quite well in fact, much of the post-Aurora Exploit banter. It boils down to this: If you let one unpatched vulnerability be the gateway to your network and all its information, you've for bigger problems than just patching that one vulnerability. Dino goes on to say that network and information segmentation can go a long way to protecting your assets.
- Undisclosed Breaches - This article details how in certain circumstances, a credit card company does not have to disclose the merchant that may have been the cause of a data breach. This seems silly to me, as a consumer I want to know which merchant was at fault, so I can find an alternate merchant to do business with. Breaches happen, and its important that we know at least who is involved so we can make intelligent decisions.
- Four Steps For Trimming Patch Management Time - This article covers some common sense tips for implementing the patch management process. How to prioritize the deployment and make sure that you test the patches. For priority, sure, you definitely want to have a sense of what can be patched, how long it takes, and what the impact will be. However, this is still just skirting the issue. Client software is the real problem, so fix it. If you are running your business and relying on Internet Explorer 6 to interact with a web application running vulnerable code, thats the real problem (not your patch management process). While there will be costs involved, your choice of the software you use has more of an impact on the security of your organization than does how fast you can patch the browser. There are other vulnerabilities lurking out there, some of which the bad guys have written exploits for, so you have to do better than just applying patches. Also, this article covers how you should go about "testing the patch". I'd also add that you need to make sure the patches have been applied to all of the systems correctly.
