"As a result, many facilities employ electronic access control on server or network equipment rooms. However, even non-exotic mechanical keys and locks can do a great job of protecting sensitive areas when properly managed."
We advise our customers to always install an inexpesive camera within the server room to see who comes, goes, and perhaps takes stuff on their way out!

Ethan, great overview. I'm not sure why you don't mention software security updates to cameras/servers. Like passwords, it's an area that tends to fall behind and nothing's more embarrassing than the VMS system hanging off the network with glaring zero day exploit vulnerability. Somebody needs to address the policy of security patches, from how they are aquired from the manufaucturer to how they're applied on an ongoing basis.
Also, it's kind of a tired subject, but somebody always wants to know about protecting the digital video streams from that gang of uber celebs who are going to rob your casino, Ocean's Twelve-style.

Did you know? I was surprised by password policy of one very known brand:
One day I needed to log into my DVR, and psw I didn't have. There was no any chance to reset it. So, I called to distributor in my country, told them serial number of DVR, and there was no problem - they send me psw of administrator!
It turns out, that DVR 'knew' special administrator psw, which every day is different (then, I get email with psw list for two week :)).
DVR wasn't connected to internet.
Question.How many very known brand can do such tricks?! Especially in IP world...

Hi,
Another (very expensive) solution is a product by waterfall security.
I am not affiliated with them in any way. They create a switch for you that replicates the protocol of the cameras used. They will allow only packets that match this protocol to pass through.
We worked with hem a few times and the solution works great. The only problem is that in most cases its more expensive than the security system itself.

I recently read about an ethernet switch that is supposed to detect breaches in the system (exactly those breaches that are the result of not following the above rules). It is made by a company called Cyber-seal, the company itself was acquired by Magal Security Systems about 2 years ago.
I don't have any first hand experience with the product, it came up in a market research I did.

We recently discovered, and are now representing, a multi-layer security enforcement tool that has recently been introduced to the market. This solution is capable of securing IP devices at the edge of the network by identifying physical and logical anomalies. Senstar’s Tungsten – Cyber Security Ethernet Switch – was specifically designed to cyber-secure physical security networks, SCADA based systems and safe-city applications.
It automatically:
Finally, and significantly, it is an economical solution that requires no additional devices or changes to the architectural design of a security system . Check it out http://www.senstarcyber.com/
With growing concerns about network security I hope the reader find this to be helpful.

Even on non-blocking switches? Non-blocking meaning that all ports can operate at full bandwidth without impacting each other.
AFAIK, most switches made these days are non-blocking.

Just a quick not on MAX address filtering. This does indeed require some administration but the biggest issue, it's not fool proof either. You can easily change the MAC address of your PC to spoof the one of a network camera for instance using a tool like SMAC

Good. Thank you for the comprehensive explanation of Network Security which ranges from software (password..) to hardware.
