Bruce Schneier has been reviewing documents from Snowden and believes that all security platforms have been compromised by governments :
Be suspicious of commercial encryption software, especially from large vendors. My guess is that most encryption products from large US companies have NSA-friendly back doors, and many foreign ones probably do as well. It’s prudent to assume that foreign products also have foreign-installed backdoors. Closed-source software is easier for the NSA to backdoor than open-source software. Systems relying on master secrets are vulnerable to the NSA, through either legal or more clandestine means.
Does anyone from Juniper, Cisco or other security company want to make a response to this ? Are they willing to confirm publicly whether their software is compromised at the request of a legal government authority ?
I want to know how far does this compromise go ? How many vulnerabilities are there in my firewalls ? Is there a backdoor in my IPS systems ?
