Incomplete Thought: In-Line Security Devices & the Fallacies Of Block Mode

June 28th, 2013 16 comments

blockadeThe results of a long-running series of extremely scientific studies has produced a Metric Crapload™ of anecdata.

Namely, hundreds of detailed discussions (read: lots of booze and whining) over the last 5 years has resulted in the following:

Most in-line security appliances (excluding firewalls) with the ability to actively dispose of traffic — services such as IPS, WAF, Anti-malware — are deployed in “monitor” or “learning” mode are rarely, if ever, enabled with automated blocking.  In essence, they are deployed as detective versus preventative security services.

I have many reasons compiled for this.

I am interested in hearing whether you agree/disagree and your reasons for such.
