Getting ready for The Standoff 2021, or Back to the Future

What would you do if you had a time machine? We will not be responsible for everyone, but we can assume that the teams of attackers, defenders and SOCs, as well as other participants of The Standoff 2021 , would not mind to be transported to the upcoming battle and see how events will unfold on the world's largest open cyber polygon, when and where the fun will happen and who will win the battle.





There is very little left before The Standoff (and the international cybersecurity forum " Positive Hack Days 10: The Beginning ") - new cyber training will start on May 18 and will last 4 days non-stop. All tickets have already been sold BUT don't be discouraged . Anyone will be able to follow the cyber battle live on The Standoff from the very morning (add it to your bookmarks so as not to forget). There you can also listen to all reports from PHDays - the full program of the forum is here .





We will not be able to build a time machine so quickly, as well as to know in advance what hackers will be able to hack and how the defenders will repel attacks, but we suggest remembering how this happened in the last cyber battle. This is a great way to refresh your impressions and pump your skills before the upcoming confrontation. All the most important from the six-day cyber training The Standoff 2020 is below.





Briefly about The Standoff and its results

From 12 to 17 November, large-scale cyber training took place at The Standoff training ground . Within the framework of the competition, 29 attacking teams and 6 defensive teams fought. For this massive cyber battle, a digital twin of an entire city was created. In this metropolis, images of transport, industrial, energy infrastructure, a business center and even a bank were presented.
