Re: No SDN Threat
True. I think the main focus should be to keep thinking of new inventive ways to keep the hackers out as possible. And eventually put an end to security threats.

Re: No SDN Threat
@dlr5288 yes, but it always seems like catch 22 as it like process never ends to plug security holes... in my books security education and thinking ahead is the key... plus constant security upgrades...

Re: No SDN Threat
I think you’re right. It does seem like hackers are always a couple steps ahead in the game. I think, however, it’ll only be a matter of time before we develope something that will slow them down.

Re: No SDN Threat
@clrmoney: The industry is exploring ways to eliminate the flaws in the software that hackers exploit. However, it seems like a tall order to reduce the current rate of flaws at about 10 for a thousand lines of code to zero. Billions of lines of code are written so the number of bugs to exploit rises exponentially.

Re: No SDN Threat
@dcawrey: The control is centralized while the actuators are distributed. But you are right that bad actors can potentially have one point of entry to the rest of the network and could also manipulate all of the actuators in a malicious way. However, there are ways to put a border between the control plane or the management services and the transportation layer or the customer services. This is explained in the Q&A with Deutsche Telekom. Also, another piece of feedback I got was that a central controller limits the attack surface and so makes it easier to find the flaws that the bad actors can exploit.

Re: No SDN Threat
The centralization of these acutators is problematic in and of itself. Being about to properly distribute these systems is imperative given what we've seen from centralized services getting hit by bad actors.

Re: No SDN Threat
Thanks for the extra info. I didn't realize this was already a widespread issue. I have no desire to see this sort of thing in person. I'd prefer it if we could leave this sort of thing in the movies.

Re: No SDN Threat
@Michelle: The entire network getting corrupted or enough to stop operating is routine now. The Sci-Fi scenario is hackers taking over the network, masquerade as the trusted authorities, seize confidential information, and then be able to remotely control other networks. The possibilities are endless for them because networks are interconnected. Unless, the criminals are stopped at the gates or spotted at the time of development.

Re: No SDN Threat
@afwriter As scary as it might be, I wonder what that an entire network might look like corrupted. It seems like it would be a serious sci-fi nightmare. It's a good case for backups and failover.

Re: No SDN Threat
Sometimes software can't eliminate it immediately and some of this malware can corrupt your hard drive and turn your computer into an expensive paperweight. I couldn't imagine a whole network being corrupted.
