Remember that time when SPAN ports ensured your network visibility and, thus, its security and the security of your data?
Oh wait, that time was never.
The SPAN port has never been a viable means to capture your data. But, in 2015, the stakes are greater than they’ve ever been, and SPAN ports remain a hindrance to fighting network security issues.
As Thor Olavsrud of CIO.com put it, “In information security circles, 2014 [was] a year of what [seemed] like a never-ending stream of cyber threats and data breaches, affecting retailers, banks, gaming networks, governments and more.
”Was 2014 an aberration? Heck no! More like a continuation of an increasing upward trend of network security issues.
Olavsrud cites Steve Durbin, Managing Director of the Information Security Forum, who, like most, believes that “the size, severity and complexity of cyber threats [will] continue increasing.”
Even beyond the growing prevalence and devastation of such problems, U.S. legislation is adding to the heightening cost of network security issues. If you’re unable to show exactly what data you’ve lost in a security breach, you will be hit with a costly fine.
And that’s where SPAN ports kill you.
To mitigate the risk of the aforementioned fines, you must be able to prove what was stolen by providing complete evidence. But, SPAN ports rarely give you such data.
Why not? Because the SPAN port:
Network TAPs have always been superior to SPAN ports. Yet, shockingly, too few network engineers understand the risks of SPAN and the overwhelming need to leverage TAPs.
A network TAP is an unhackable device. It has no IP address. It provides complete network visibility and will stop capturing data only if its cables are physically disconnected from your network. It also preserves your full duplex links.
You could continue to risk your network and job security by sticking with the SPAN port and all of its issues. Or, you could bolster your security with network TAPs and ensure a plane of visibility.
Ultimately, the choice is yours.
