Friea Berg at Splunk wrote a nice article summarizing some of the latest highlights of how Splunk and Cisco have been teaming up to provide end to end security visibility and protection. You can find the original post HERE.
Over the past 7 years Cisco and Splunk have built a broad and multi-faceted relationship.
I see a lot of hesitation from administrators when having a conversation about cloud based security. People seem to be uneasy with the idea of having anything security related managed outside of their company walls. Some administrators express concerns that there is a potential weakness opening up a connection from their inside network to the cloud (even though it is encrypted) while others feel uneasy about having people outside their staff accessing equipment for maintenance or other purposes. I’ve also had the question “what happens if a client sharing a security device in the cloud gets compromised? Will that impact our business”? (I’ve never heard of this happening and there are hundreds of cloud offerings available today). These are just a few concerns that gives cloud based security a bad reputation before it is evaluated for its true potential.
Cloud Security should be looked at as a method of outsourcing security. Why would you want to do this? There are many benefits and for some situations such as locations spread across the world, cloud is the only feasible answer. Here are some of the top benefits of going cloud based security.

Pierluigi Paganini from Security Affairs posted a great article about how Cisco NetFlow could possibly be used to identify Tor clients. The idea is a NetFlow sensor could monitor a certain percent of random generated Tor circuits and possibly link clients back to their users. The original post can be found HERE. Here is the post.
The research revealed that more than 81 percent of Tor clients can be de-anonymized by exploiting a new traffic analysis attack based on Netflow technology.
A team of researchers conducted a study between 2008 and 2014 on the de-anonymization of the Tor users, the team worked to disclose their originating IP addresses. Continue reading →
Cisco announced yesterday that they intend to acquire Neohapsis. Neohapsis is a security, risk and compliance company, which is a very interesting move by Cisco. Many people not only want data from security reports, but also desire how that data will impact their business. This means how changes or risk can impact compliance to mandatory regulations as well as how much impact could a vulnerability have to a system. Neohapsis is a services based company so this seems to be a security services play yet could also trickle in Cisco products.It would be really cool to see more compliancy based reporting in future Cisco products as an outcome of this acquisition.
Cisco acquired the leader for identifying day zero threats ThreatGRID around may of 2014. ThreatGRID’s statement “The First Unified Malware Analysis and Threat Intelligence Solution” sounds like a mouthful however represents its purpose of going beyond what most “sandbox” technologies accomplish in this market space. What is also interesting is this technology is being moved into other Cisco security offerings now that they are part of Cisco’s breach detection strategy. Continue reading →
The Internet Security Research Group (ISRT) along with Mozilla Corporation, Cisco Systems, Akamai Tech, Electronic Frontier Foundation and IdenTrust will be offering a new free certificate authority service this up coming 2015 summer (learn more HERE). The concept is the Internet is a dangerous place and enabling protection is a hassle for many businesses. The reason behind this is enabling basic server certificates can be painful involving multiple steps and a cost. Lets Encrypt is offering the following principles to simplify the process.

There are many reasons people invest in security. The best reason is having the desire to avoid being breached however sometimes wanting the best security doesn’t justify the investment. Many decision makers have to juggle improving the infrastructure, investing in the latest flashy technology such as high end video, etc. along with keeping things secure. Usually the flashy stuff outshines security until something with teeth forces the focus back on security. A prime example is meeting mandated regulatory compliance. Being out of compliant to many regulations could mean pricy fines as well as possibly litigation actions. This is good news for the IT guy that wants to get his security budget requests placed at the top of the stack.
To help meet regulatory compliance, Cisco has released validated design guides for general security as well as specific market verticals FOUND HERE. Continue reading →
Cisco just released the latest version of ISE aka Identity Services Engine version 1.3 on Oct 31st. ISE is Cisco’s flagship access control technology (more on ISE found HERE and how to build a Lab found HERE). In summary, ISE can tell you who and what is on the network, provision the proper access and even remediate devices that are out of expected security posture. You can find the formal release notes for ISE 1.3 HERE.
ISE 1.3’s main new features revolve around providing enhanced guest services such as simplifying the process to on-board new mobile devices. There are other improvements I’ll cover in this post as well. Lets take a look at the new 1.3 version of ISE. Continue reading →
