One of the great things about a blog is that your rants can live on forever. With that said, I decided to start storing my long term rants in my blog. Every time I think of rant that I want to save for a few years, I'll write it here. Then when I can't think of anything to rant about, I can look here. 1.

One of the great things about a blog is that your rants can live on forever. With that said, I decided to start storing my long term rants in my blog. Every time I think of rant that I want to save for a few years, I’ll write it here. Then when I can’t think of anything to rant about, I can look here.

1. We need a better centralized reporting methodology for reporting high-risk malware and malicious hacker attacks against the Internet.

2. More operating systems and applications need “deny-by-default” rules and configuration. Deny-by-default rules are the norm in firewalls, but not-much else. Security is always a risk/benefit trade off-a decision between normal end-user functionality and increased default security. Unfortunately, increased end-user functionality is often choosen over security, even when the level of increased end-user functionality could not be justified as compared to the risk.

For example, why does Microsoft Windows allow every file type to be automatically executed by any user when the vast majority are not used for legitimate reasons? For instance, the latest Windows help exploit vulnerability relies on the existence and user of files ending in .hhp. Very few users that I know use these files, yet they are allowed to automatically execute in Windows. How about last month’s WMF vulnerability. Although the WMF vulnerability could use any file extension it wanted, most of the public exploits have used the .WMF extension. Probably less than 5% of Windows users use WMF files for legitimate reasons, so why allow it by default? I routinely recommend to my customers that they disable over 150 file extensions more likely to be used maliciously than legitimately in most environments. It would be more efficient if Microsoft provided a utility that allowed sys admins to use a deny-by-default, allow-by-exception rule for file executions. Microsoft could tell us the the extensions that Windows needs by default, and other common file extensions (e.g. .DOC, .XLS, etc.) that most users needed. But we should be able to block the majority by default.

I’ll update my Ongong Long-Term Rant List as ideas re-appear in my head.
