ProxyClient, Error 400 and MS12-006

This is just a case of bad timing. Back in August, BlueCoat implemented some changes to the BlueCoat WebFilter.  It introduced some new categories and renamed some other categories.   On the ProxySG, no change was necessary for the renamed categories.   However for ProxyClient (the client side install that provides protection when off the corporate network), …

BlueCoat Support

I had my first experience with the “new” BlueCoat support model last week. Around the time we switched from using third-party support back to BlueCoat, BlueCoat announced a change to support.   It sounded like they were making official what I had always experienced.   The first person you talk to will gather information for the more knowledgeable …

The WebFilter and the Wikileak

When Wikileaks was first posted, I wondered to myself whether people with clearances could get themselves in trouble by viewing the website.   I was on vacation at the time, but 3 days later an email came out from the facility security officer.   Like many Federal government employees, we received a memo saying we cannot access those websites using …

BlueCoat ProxyClient 3.2.2.4

I was doing some testing with BlueCoat ProxyClient 3.2.2.3 and was seeing weird things. ProxyClient is software installed on laptops so when the client is outside the corporation it will still do URL filtering with WebPulse.    I’ve written about it before and it seems like a nice middle ground between no protection and having to …

BlueCoat DNS

I’ve been having some issues with BlueCoat DNS for a few days now.   Since I’m not seeing a huge outcry, I”m wondering if its just me. It started with warning emails from each BlueCoat appliance saying they “Download of the BlueCoat WebFilter database failed.”   It is trying to download a file from https://list.bluecoat.com.   A WHOIS …

BlueCoat ProxyClient

As I warned, I attended a BlueCoat seminar on Wednesday and I’m getting a few days worth of blog posts from that. In March of 2009, I blogged that I was testing the BlueCoat ProxyClient.   The ProxyClient provides URL filtering via WebPulse and also attempts to provide acceleration to VPN users and users on slower …

BlueCoat WebPulse

As I mentioned, I was at a BlueCoat Web Security briefing on Wednesday. Most of the talks covered things I already knew.   I’m well aware of BlueCoat’s product line, and the web security stuff I received that in a meeting earlier in the year.   But the security stuff was good review.   It is rather interesting how …

BlueCoat Security Briefing

On Wednesday, I went to the BlueCoat Security Briefing at the Tyson’s Corner Marriott.  The big news for me was that our hardware (SG810-B and SG510-B) which I’d been led to believe was going to end-of-support in November is good for another year.  Even today the end of life matrix says TBD, but typically end of life …

Zscaler protects against IE Zero Day

On Tuesday, as seems to be the custom, Microsoft released patches and announced a new zero day in Internet Explorer. MSKB 981374 is a remote code execution in IE6 and IE7. Who know that being on IE5 could ever be a good thing. The KB says Microsoft released details to venders in their Microsoft Active …
