The blockchain has emerged as a revolutionary technology with the potential to redefine how data is managed, stored, and shared. While initially associated with cryptocurrencies like Bitcoin, the blockchain’s applications extend far beyond finance, impacting industries ranging from healthcare to supply chain management. One of the blockchain’s key promises lies in ensuring data consistency, transparency, and privacy, critical elements in an interconnected and data-driven world.

The Sarbanes-Oxley Act (SOX) requires publicly traded companies to declare and adopt a framework that the business will use to “define and assess internal controls.” In response, most publicly traded companies have adopted one of two frameworks that meet the SOX requirements: the Committee of Sponsoring Organizations (COSO) internal control framework and the IT Governance Institute’s Control Objectives for Information and Related Technology (COBIT).

A One-time password is an automatically generated numeric code that can only be used once. One-time passwords are used to authenticate users before they can access an account or system and are often used as a form of Multi-Factor Authentication (MFA) to add additional verification factors to an account. Many companies, such as financial institutions, send their users one-time passwords to verify their identity before they grant them access to sensitive accounts and information.

In my previous blog post, What you can’t do with Kubernetes network policies (unless you use Calico): Policies to all namespaces or pods, I talked about this use case from the list of nine things you cannot implement using basic Kubernetes network policy — policies to all namespaces or pods. In this blog post, we’ll be focusing on the next use case — advanced policy querying and reachability tooling.

As kids, many of us felt anticipation, excitement, and maybe even nervousness during the holiday season. Had we been good enough to get the Gameboy, Barbie Dream House, or Etch a Sketch we’d been pining for, or were we just going to get a big ol’ lump of coal?

Security-oriented organizations continuously identify, monitor, and manage internet-connected assets to protect them from emerging attack vectors and potential vulnerabilities. Security teams go through every element of the organization’s security posture – from firewalls and cloud-hosted assets to endpoint devices and entry points – looking for opportunities to reduce security risks. This process is called attack surface management.

Hackers exploited an API vulnerability that had been exposed since June the previous year. This gave them access to the platform’s security system and allowed them to leak sensitive information on millions of users. This breach occurred because the organization’s firewalls were not configured to examine API traffic with enough scrutiny.
