A Breaking Change for all Android-based Teams Devices
“The CA system is broken, but it works because broken systems tend to be better for society, which needs fluidity in the face of complicated social constructs,” Schneier said. “Systems that are broken but work are very common in the real world: Front door locks are surprisingly pickable. Think of faxed signatures, for example. It’s […]
The blog is reaching the end of its third year online. I wrote my 2007 roundup at about this time last year and now its time to take a look at what happened in 2008. Visitor Growth In 2007 I was relying on Awstats provided by my web host for visitor statistics. Those stats showed […]
With the right configuration and ongoing tuning the built in Exchange Server 2007 anti-spam features can be effective in many environments. One thing I’m not a fan of though is the quarantine feature. You can read more about it in my latest post to AllSpammedUp.com here. Link: Managing spam quarantine for Exchange Server 2007
I’ve been working on a post about the current economic client and how best to handle it as an IT professional.

Over at AllSpammedUp.com I’ve written an article about protecting Exchange Server 2007 from Directory Harvesting Attacks. In many Exchange Server 2007 environments incoming email is received directly by an internet-facing Hub Transport server. By default the transport server will use recipient lookups to notify the connecting host whether an email address is valid or not. […]
To quote Bruce Schneier, “well-designed security systems fail gracefully”. This means for example when the ISA firewall service fails it closes off network connectivity entirely (ie retains security) instead of opening your entire network up (ie decreases security). This week SonicWALL’s license servers suffered a glitch rendering thousands of customer units useless and leaving the […]
I often get asked which is the better Exchange certification to pursue for someone who wants to work as an Exchange administrator or consultant.
