Responsive Security in Action

In 2013, our internal Information Security team carried out a series of controlled anti-phishing exercises. The purpose was to raise employees' awareness of potential spear phishing attacks through emails. Spear phishing has been a common first step for Advanced Persistent Threat (APT) attacks to gain access to a user's system before launching further attacks at internal targets. As such, if employees are vigilant against such attack patterns, we should effectively reduce the risk of successful APT attacks involving email phishing.

Network Access Control Sure Isn’t What It Used to Be…

Chances are you might be reading this blogpost on a device other than a laptop or desktop computer.  I’d also wager that the device you’re using to read this post handles double-duty – that is, you use it for both work (e.g., checking email, reviewing confidential documents) and play (e.g., Vine, Flappy Bird, social media).

Continuous Protection on the Endpoint: Show Me

Advanced malware is dynamic, elusive, and evasive. Once it slithers into the organization’s extended network, it can very quickly proliferate, cause problems, and remain undetected by traditional point-in-time security tools. These tools poll or scan endpoints for malware or indicators of compromise at a moment in time, and then do not evaluate again until the […]

Cloudy with a Chance of Scalable Malware Protection

The proven value of Software-as-a-Service (SaaS) solutions, that we all access daily from multiple devices, makes the cloud a reality, but SaaS also creates an environment in which anyone, anywhere in an organization, can be attacked at any time. Modern Networks go beyond traditional walls and include data centers, endpoints, virtual and  mobile – all […]

A Circular Problem in Current Information Security Principles

Editor’s Note: In this second installment of the blog series on more responsive security, we take a closer look at the circular problems associated with four common security principles in managing “weak link” risks in Information Technology organizations. Before discussing what constitutes this responsive approach to security, let us first look at a few of […]

Key Considerations for Threat-Based Security Programs

As we often say at Cisco, every business is a security business. That’s been true ever since widespread online presence led to widespread cyber threats. It became even more applicable as those threats became more sophisticated and less detectable. And now, with the Internet of Everything (IoE), that phrase is more relevant than ever before. […]

A Model for Evaluating Breach Detection Readiness

Given that modern attacks are complex and sophisticated, there is not a single product or tool that will ever be 100% effective at detecting threats. Prevention eventually fails. Therefore, you need protection before, during, and after an attack. Modern-day networks are large and complicated. It is a nightmare for incident response teams and security investigators […]
