    Zero Trust & The Flaming Sword of Justice

    Security breaches pervade the headlines. What was seen as a rare instance just 5 years ago now seems to occupy the daily news cycle. A lot of these data breaches are made possible due to missteps and misconfigurations. There are many security issues that are introduced into website authentication mechanisms that further compound the security issues in addition to enforcing bad behavior by the end users. Security debt is a real problem for the vast majority of organizations in the world today and the attackers will utilize this to their advantage. In addition to keeping system hygiene at front of mind defenders need to focus on proper network zone segmentation or, as it more popular term these days, zero trust networks. The old conceptual style of a castle wall and moat to defend a network was deprecated several years ago. As a result of the dissolution of the traditional perimeter a stronger focus has to be placed on the strength of authentication, authorization and trust models for the users. 

    The antiquated notion of an information security practitioner running through the office brandishing their flaming sword of justice above their heads screaming “thou shall not pass” has at long last reached it’s denouement. Whether you are responsible for the security in a financial organization or one that makes teddy bears it is necessary to adapt and learn to trust but, verify.

    PANEL: Privacy vs Security - the good, the bad & the ugly

    Privacy has been in the spotlight in recent years with revelation about how much access both government agencies and more recently social networks have to personal data. However in a catch-22 situation both privacy at the expense of security and security at the expense of privacy seem to be equally unpalletable. So how does one strike a balance between two sides so far at odds with each other and find a middle ground acceptable to all parties?
