A vulnerability is a weakness which allows an attacker to reduce a system's information assurance. Vulnerability is the intersection of three elements: a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness, known as the attack surface. Vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities. Other vulnerabilities include security risks, security defects and constructs in programming languages that are difficult to use properly.

The world has now had time to recover and mitigate damage from the widespread WannaCry ransomware attack. We evaluated what it has left in its wake. Tallied damage includes:
 
More than 150 countries.
Currently $111,996.86 has been paid in bitcoin so far to decrypt files.
Around 16 of England’s National Health System organizations affected, with doctors resorting to pen and paper to complete patient records.
Renault, a European auto manufacturer, kept a French plant—that employs 3500 people—closed Monday, May 28th as a “preventative” measure.
 
Learn how to secure your data and prepare against future threats by taking our June Course of the Month covering ransomware prevention and preparation.

The sad part is a common failure in projects is failing to ask users for requirements.

The NHS does not consider the opinion of NURSES and DOCTORS worthy!

Very Wrong, and they wonder why, they are all leaving and retiring, now leaving a brain drain in the NHS!

You need to install software like sophos intercept x in computers inside your network to block it.

Personally, I'm just avoiding opening any Word docs from anyone I don't know... And to some extent, even from people I do know... Most of my document usage these days is with Google Docs, so it's pretty rare that I need a Word doc!
