Find Your Security Vulnerability Before Hackers Find It For You

Find Your Security Vulnerability Before Hackers Find It For You
 Every Network Has a Security Vulnerability Where is Yours?


One of the top questions on the minds of network security personnel is "how do I reduce my security risk?" Even for smaller organizations, this is important because every network has a weakness. But do you know where you are the most vulnerable? Wouldn't you like to fix the problem now, before a hacker exploits it?

It Doesn't Take a Brain Surgeon (Paul W. Smith,)

 

It Doesn't Take a Brain Surgeon (Paul W. Smith,)

For many of us, college is that season of life when we are compelled to choose a career path, long before we have any idea of who we are or what we want. Back in my college days, many of my fellow students were the progeny of doctors, lawyers and engineers who saw no other viable option than to follow in the footsteps of their parents. Others who had a propensity to argue chose to pursue the law, while those geeky types who were always taking things apart as kids went into engineering. And those rare students with a 5.0 GPA (how is that even possible?) and whose faces were always buried in a book? They were destined for Med School.

TAP versus SPAN, RSPAN or VACL?

TAP versus SPAN, RSPAN or VACL?

Is using a SPAN port a viable data access technology for today’s business critical networks, especially with today’s ever increasing pressure to satisfy Data Security Compliance, Lawful Intercept and Deep Packet Inspection requirements? In today’s world we now have the GDPR requirements that “Require” 100% data inspection and retention! Plus, Deep Packet Inspection with Firewalls must have full visibility of every frame and part thereof!

So “REAL” TAPs both Electrical and Photonic are even more in demand!

Quick Faraday bag test with my NetAlly Aircheck

Faraday bag test with my NetAlly Aircheck
I thought I would see if these faraday bags can really block RF signals, so I used my NetAlly Aircheck to monitor my cell phone's wifi while I pinged it from another computer. I figured I have the tool and a client asked me if those bags actually work, so I figured why not give it a try.

I find that a lot of portable wifi devices cycle the wifi off if there isn’t any traffic, hence the ping from the other computer.

I was pleasantly surprised that the bag did block the wifi signal from my phone. I repeated the test several times to be sure and even noticed that the wifi icon on my phone actually disappeared.

4 Ways Big Data Network Monitoring Benefits Your Business!

 By its very nature, big data exceeds the capability of most corporate networks.

4 Ways Big Data Network Monitoring Benefits Your Business!

Simply due to the sheer volumes of data that big data projects use, traditional networks are finding themselves unable to cope with the pressures. Thus, new ways of managing data have had to be created.

After all, according to IDC, there will be 450 billion Internet transactions every day. Walmart now processes over 1 million customer transactions per hour, generating 2.5 petabytes of data. Every minute, YouTube produces 48 hours of new video content. Every day, Facebook processes 100 gigabytes of data.
