Lancope is a NetFlow based tool that can turn your network into a gigantic sensor grid. This includes routers, switches, wireless access points, virtual systems aka servers in your data center and so on. So rather than having a handful of security tools looking for threats, your entire network takes part in your security defense against cyber attacks. I’ve wrote about Lancope HERE as well as how to build your own Lancope lab HERE. The Lancope team runs a blog found HERE that has provided posts about using their solution to identify the latest cyber attacks. Some interesting articles recently posted focus on threats like Heartbleed, Putter Panda and Saffron Rose. Continue reading
Researchers at Duo Labs, the advanced research team at Duo Security, discovered that it is possible to bypass PayPal’s two-factor authentication (the Security Key mechanism, in PayPal nomenclature). The vulnerability lies primarily in the authentication flow for the PayPal API web service (api.paypal.com) — an API used by PayPal’s official mobile applications, as well as numerous third-party merchants and apps — but also partially in the official mobile apps themselves.

The Splunk and Cisco team delivered a great talk at this past Cisco Live event in San Francisco. The talk covered the value of integrating Splunk with Cisco Cloud and Managed Security services. Continue reading
Kellep Charles from SecurityOrb interviewed me a few weeks back about my book as well as other general security topics. You can find the recording HERE or on the SecurityORB website. I was fighting a cold so my apologies for the raspy voice.
For those interested in the book, below is a discount code you can use provided by SecurityORB. The link to the book is on the right side of this blog. Continue reading
Cisco acquired Sourcefire in 2013 as part of a strategic move to enhance Cisco’s security portfolio. Sourcefire’s catalog covers IPS/IDS, Application Security and Control, Firewalling, Malware Detection and a slew of open source tools such as SNORT, ClamAV, and Razorback.
One key piece to the Sourcefire puzzle is the management of the various solutions. This is done through Defense Center, which is the centralized management tool used for visibility of security and network events across the entire network. This post will provide a overview of using Defense Center from a administrative viewpoint.

The people from Cyber Crimebusters developed a Infographic about how Internet forensics has changed criminal investigations. The original can be found HERE.
The interesting points to me are how social media and mobile devices are becoming a common source for investigations. I find it humorous when people post pictures of themselves doing crazy things on social media sources and shocked when that comes back to haunt them later such as in job interviews. I’ve provided examples of how I used people’s data on Facebook (previous job roles, friend’s current location, etc) to pretend I’m a friend from years ago using a fake Facebook ID to obtain data during an authorized penetration testing (more on that HERE). Its critical to know what you have public about yourself and question anybody that seems fishy. Trust me, its better to ask for proof of identity when you don’t know who you are speaking with rather than assume the wrong person is a trusted friend. Continue reading
Nicole Perlroth wrote a interesting post on the NewYorkTimes blog about a new type of Ransomware and Cisco’s view as it spreads in the wild. The original post can be found HERE.
It has been mere days since federal agents seized control of computer networks used by hackers to infect victims with CryptoLocker, a piece of malware known as “ransomware,” which encrypts the contents of computing devices so hackers can demand a ransom to decrypt it. More on Ransomware such as CryptoLocker can be found HERE.
Now security researchers are seeing an influx of another form of ransomware, called Cryptowall. Continue reading
Today the folks at openssl.org published a new vulnerability found in OpenSSL encryption. For those that are not aware, OpenSSL is found on approximately 66% of all websites found on the Internet. You can find the official notice on this vulnerability HERE as well as details posted below. This time its a known bug and yet again, we are being told by the openssl team the remediation for this is to upgrade to the latest version of OpenSSL using the recently patches being released.

Every once in a while I like to do a product review. Next up is the meraki MX60 (shown above on the left next to the Meraki Z1). The official MX60 data sheet can be found HERE. The MX60 comes with or without wireless capabilities hence the MX60W means wireless while the one used in this post is a MX60. Outside of that, both models are the same and considered the low end / home model as shown in the next image. Continue reading
