Should You Whitelist Your Vulnerability Scanning Service Provider?

Unlike consultant-led penetration testing, periodic or continual vulnerability scanning programs have to operate harmoniously with a corporation's perimeter defenses. Firewalls, intrusion prevention systems, web proxies, dynamic malware analysis systems, and even content delivery networks, are deployed to protect against the continuous probes and exploit attempts of remote adversaries -- yet they need to ignore (or at least not escalate) similar probes and tests being launched by the managed security service providers an organization has employed to identify and alert upon any new vulnerabilities within the infrastructure or applications that are to be protected. more»

Global Paradigms We Relied Upon Were Destroyed Overnight - How Prepared Are You for New Realities?

Unprecedented new Political and Cyber Security Threats are happening at a scale that has never been witnessed before. These threats are large and malicious enough to take down nuclear programs, render oil refineries inoperable, and take billion-dollar websites offline (not to mention smaller ones). Recent events confirm that NO ONE IS IMMUNE. Despite the obvious warning signs, Internet business stakeholders the world over continue to act as if nothing has changed, and seem unaware that global paradigms have undergone a seismic shift almost overnight. more»

Understanding the Threat Landscape: Basic Methodologies for Tracking Attack Campaigns

The indicators of compromise (IOCs) outlined in my last blog post can be used as a baseline for developing intrusion sets and tracking attack campaigns and threat actors. When launching an attack, threat actors use a variety of vectors and infrastructure, which Verisign iDefense analysts -- as well as analysts across the cybersecurity community -- correlate to group attacks, tracking actors and determining attack methods. more»

Understanding the Threat Landscape: Indicators of Compromise (IOCs)

I previously provided a brief overview of how Verisign iDefense characterizes threat actors and their motivations through adversarial analysis. Not only do security professionals need to be aware of the kinds of actors they are up against, but they should also be aware of the tactical data fundamentals associated with cyber-attacks most commonly referred to as indicators of compromise (IOCs). Understanding the different types of tactical IOCs can allow for quick detection of a breach... more»

Understanding the Threat Landscape: Cyber-Attack Actors and Motivations

The threat landscape has rapidly expanded over the past few years, and shows no signs of contracting. With major establishments in both the public and private sectors falling victim to cyber-attacks, it is critical for organizations to identify the motivations, modus operandi (MO) and objectives of adversaries in order to adequately and effectively defend their networks. Understanding the taxonomy of cyber-attacks is the first step in preparing an organization against exposure to them. more»

The Longevity of the Three-Napkin Protocol

It is not often I go out to my driveway to pick up the Washington Post -- yes, I still enjoy reading a real physical paper, perhaps a sign of age -- and the headline is NOT about how the (insert DC sports team here) lost last night but is instead is about an IT technology. That technology is the Border Gateway Protocol (BGP), a major Internet protocol that has been around for more than a quarter century, before the Internet was commercialized and before most people even knew what the Internet was. more»

Diving Into the DNS

If you are at all interested in how the Internet's Domain Name System (DNS) works, then one of the most rewarding meetings that is dedicated to this topic is the DNS OARC workshops. I attended the spring workshop in Amsterdam in early May, and the following are my impressions from the presentations and discussion. What makes these meetings unique in the context of DNS is the way it combines operations and research, bringing together researchers, builders and maintainers of DNS software systems, and operators of DNS infrastructure services into a single room and a broad and insightful conversation. more»

M3AAWG & i2Coalition Collaborate on Best Practices on Anti-Abuse in Hosting & Cloud Environments

I am excited to announce the recent release of the industry first Best Common Practices document for Cloud and Hosting providers for addressing abuse issues that was created by M3AAWG and the i2Coalition. M3AAWG has been collaborating with the Best Practices Working Group of the i2Coalition over the past 2 years to discuss ways to solve malicious activity within hosting and cloud ecosystems.  more»

The Economics of Magic

Arthur C. Clarke said any sufficiently advanced technology is indistinguishable from magic. Milton Friedman said there's no such thing as a free lunch. The validity of the former statement does not invalidate the later. From this we can see that even magic has a price. Hence, its application is subject to cost-benefit analysis. There are many developing technologies that may eventually qualify as magic. more»

The Internet of Stupid Things

In those circles where Internet prognostications abound and policy makers flock to hear grand visions of the future, we often hear about the boundless future represented by "The Internet of Things". This phrase encompasses some decades of the computing industry's transition from computers as esoteric piece of engineering affordable only by nations, to mainframes, desktops, laptops, handhelds, and now wrist computers. Where next? more»
