Three takeaways for a Small Business from the Microsoft Exchange hack

    I heard this so many times: “My company is too small to be the target of an advanced attack”. Unfortunately, this is not true and the recent cyber-attacks on Microsoft Exchange servers clearly show it. Compared to the recent SolarWinds Orion security breach that directly affected mostly large organizations, the Exchange vulnerabilities were used to attack in excess of 30.000 organizations in the US alone, mostly small businesses and local government offices.  Here are the three lessons that a small… Read More »Three takeaways for a Small Business from the Microsoft Exchange hack

    A Practical Approach to Cyber Resilience – Part 1 of a 3 Part Series

      In a previous blog, I looked at the key differences between cybersecurity and cyber-resilience, and why cyber-resilience is a better approach for organizations to follow in 2021 because it is holistic.

NIST Special Publication 800-160, Developing Cyber Resilient Systems, is one the most comprehensive resources available for those enrolled on this journey. Although a bit difficult to navigate, the value of this publication is in its… Read More »A Practical Approach to Cyber Resilience – Part 1 of a 3 Part Series

        Given the increased dependency on digital technologies for daily operations it’s not a surprise that organizations are concerned about cyber threats and the risks these are posing to their operations. But what is the best approach to this problem? Should an organization focus on cybersecurity or on cyber-resilience?

                The recent security incident involving Solarwinds Orion proves that cybersecurity is a team game. We all use software developed by a wide range of providers (and we will continue to do so). Any successful attack on one of these vendors (suppliers) can have negative consequences on all users of their software solutions. Solarwinds was targeted by a complex attack (most probably state-sponsored) that successfully deployed malicious code into their IT management software product Orion (The backdoor code was hidden within… Read More »Defeating supply chain attacks together
