I have recently seen a uptick in DDoS / DoS attacks against my customers and asked questions such as “how easy is it to perform these attacks?”, “who launches these attacks?” and “how can I defend against such attacks?”. I have spoke about this topic in the past however will provide both the executing and defending side of DoS in this post. Continue reading →
Alicia Butler from Lancope wrote a interesting post about the 5th Myths about NetFlow. You can find the original post HERE.
NetFlow is an important tool for incident responders, providing valuable insight into the activities that take place on organizations networks. NetFlow is capable of summarizing information about network traffic into brief records that may be maintained indefinitely, providing a running history of network connections that may be referenced during incident response.
With all the good NetFlow brings, there are still some misconceptions about NetFlow that need to be dispelled. Continue reading →
Controlling who and what access your network is a critical element to keep your resources safe from malicious threats. Network Admission Control (NAC) solutions like the Cisco Identity Services Engine (ISE) can police who and what is permitted network access as well as enforce policy for those devices. Examples would be permitting an administrator with a government furnished Windows 7 laptop access to VLAN 10, which holds internal servers, while provisioning a marketing professional’s iPad with VLAN 20 access, which is limited to Internet and email through the use of ACLs.

Lancope enables visibility for security and network performance. Security capabilities focus on identifying insider threats such as botnets, malware and data loss using non-signature network wide correlation of all traffic. Pretty much anything touching the physical or virtual network leaves a footprint known as NetFlow that is investigated for malicious intent and performance statics.
Lancope offers a virtual and physical appliance option for the StealthWatch technology making it easy to build a lab. This post will explain how to build a simple Lancope lab integrated with Cisco ISE 1.2 beta using an Apple Mac mini server hosting vSphere ESXI 5.1 with ASA 5505 firewall. Continue reading →
Today’s threat landscape is loaded with malicious websites, malware and other risks that attack users every nanosecond of the day. There isn’t a single product available that can guarantee protection from cyber threats. Older solutions leveraging static technologies such as signatures are not good enough. The best approach for dealing with advanced threats is continuously monitoring the entire network through layering security technologies. Continue reading →
Last year Aamir Lakhani and Joseph Muniz developed a fake identity known as Emily Williams with the purpose of compromising a specific target using social media. We created Emily Williams based on research from Robin Sage, which showcased how a fake identity could obtain sensitive information from social media resources. We wondered if a similar approach could be used for targeted attacks and developed Emily Williams for that purpose. More information on developing Emily Williams via Part 1 of this project can be found HERE. Continue reading →

Emily Williams and Robin Sage
Emily Williams and Robin Sage don’t exist in the real world. They are fake social network accounts designed to obtain sensitive information. Robin Sage was created in late 2009 to obtain information from intelligence on US military personnel. Her story was presented at the Black Hat hacker conference upsetting many people by exposing the type of sensitive data provided over social networks. Joey Muniz and Aamir Lakhani decided to go one-step further and ask the hard question: “what else can happen outside of data being leaked over social networks”. We decided to find out using EmilyWilliams. Continue reading →
A common saying is ” Amateurs Hack Systems, Professionals Hack People”. Social engineering is the art of manipulating people into performing actions or divulging confidential information. People fall for social engineering tricks based on their instinct to be helpful and trusting. The typical attacker never comes face-to-face with a victim using deception through email, social networks or over the phone. Continue reading →
