Baking security into switches

2008-02-25 00:00:00 by HASH0x8b047b4 in Network World on Security
 
Last month, I read about Juniper entering the switch market for the first time and Cisco introducing a new set of data center switches. I'm wondering how these new switches support the idea of building more security into switches

Most switches help in complying with secure management best practices

2008-03-24 00:00:00 by HASH0x847334c in Network World on Security
 
In assessing switch management and security, we sought to answer three questions: Did devices follow current best practices by default? Could users configure switches to follow these best practices? And could switches be wiped clean of any sensitive information before being taken out of deployment

How we tested the switches

2008-03-24 00:00:00 by HASH0x8473034 in Network World on Security
 
We assessed switches with 10 sets of tests covering L2 and L3 unicast performance; IGMP group multicast capacity; L2 and L3 multicast performance; NAC/802.1X; storm control; power consumption; switch manageability, security, and usability; and switch features

TippingPoint chief architect says embedding security in switches and routers is a fools errand

...switches and routers. After about a year of trying to do this, he says that he realized it was a "fools errand" because security is evolving so much quicker than networking. I don't know, but that is probably not the opinion of Cisco, HP ProCurve, Foundry, Extreme, Enterasys and Juniper who all seem to be doing exactly that. Perhaps it had...

Kill Switches and Remote Control

2008-07-01 06:48:37 by schneier in Schneier on Security
 
...switches on their own equipment. Microsoft is doing some of the most creative thinking along these lines, with something it's calling " Digital Manners Policies ." According to its patent application , DMP-enabled devices would accept broadcast "orders" limiting capabilities. Cellphones could be remotely set to vibrate mode in restaurants and...

Every network has a firewall, shouldnt a virtual one have the same?

2008-02-10 15:07:45 by John Peterson in Security In The Virtual World
 
...Switches are not equivalent to physical switches. You can at least set up ACL's (Access Control Lists) on physical switches to isolate traffic but in the Virtual Switches you can not So without this ACL type of isolation you are even more insecure than your physical networks. No Firewalls and no ACL capable switches What needs to be secured...

...switches are not as feature rich as physical switches we are left unable to do many of the things we've done in the physical world that enables visibility. One of the features that exists in physical switches that is commonly used as a security and visibility tool is Netflow Over the past week or so I've begun speaking with VMWare customers...

The Oracle speaks

...switches or Extreme Switches then you can do dynamic ACLs per port. Similar to how you assign a VLAN via RADIUS attributes, you can assign ACLs for that port in addition to assigning a VLAN. This is great if you have the right switches. It helps protect the other endpoints within a quarantine VLAN and adds an extra layer of security. Cisco...
