Zwembad winterklaar set BASIC tot 8 x 4 meter

Wilt u uw zwembad klaarmaken voor de winter? Dan heeft u met deze winterklaarset alle basisbenodigdheden voor een zwembad tot 8 x 4 meter. De winterdrijvers en gizzmo zijn ervoor bedoeld om de druk van ijs op te vangen. Water zet, wanneer het bevriest, uit. Door het plaatsen van winterdrijvers en een gizzmo voorkomt u onnodige beschadiging aan uw zwembad. Met de meegeleverde wintervloeistof voorkomt u kalkvorming en daarmee ook de voortplanting van algen. Zo wordt uw zwembad tijdens de winter niet groen. Wintervloeistof dient 2 tot 3 maanden na de eerste toediening nogmaals toegediend te worden.

Hoe gebruikt u ACTI wintervloeistof 5 liter?

Zorg ervoor dat het zwemwater schoon is voordat u de ACTI wintervloeistof 5 liter toedient. Verwijder al het vuil uit het water en voer een behandeling met chloorschok uit. Na 24 uur kunt u beginnen met het toedienen van de wintervloeistof. De hoeveelheid die u nodig heeft hangt af van de inhoud van uw zwembad. Per 30.000 liter water heeft u 1 liter vloeistof nodig. Laat na het toedienen van het middel de pomp 3 uur draaien op de circulatie stand, zodat het middel goed door het zwemwater verspreid wordt. Om het gehele seizoen zeker te zijn is het belangrijk om de behandeling elke 2 tot 3 maanden te herhalen.

Inhoud pakket

  • 18x Zwembad winterdrijver 50 x 25 x 5 cm
  • 1x ACTI wintervloeistof 5 liter
  • 2x Gizzmo voor skimmers (1,5"/2" aansluiting)

A #MustRead for cybersecurity practitioners
Format: Kindle
Rick Howard's latest book is the ultimate reference for cybersecurity practitioners, making it an essential read for anyone in the field. With his straightforward and refreshingly irreverent writing style, coupled with his profound technical knowledge, Rick has created a narrative that is easy to understand and grasp. He delves into the foundational aspect of cybersecurity, which he refers to as the cybersecurity first principle, which he then it to specific high-impact strategies. The book has eight well-written chapters providing a comprehensive overview of those strategies. Importantly, Rick then offers an up-to-date and thorough exploration of the complementary capabilities (tactical-level tools) that can be utilized to "reduce the probability of material impact due to a cyber event" - the cyber first principle. In the concluding chapter, Rick succinctly summarizes his contribution to the field, stating, "And that's it. Those are all the tools you need to design, build, and enhance a cybersecurity program based on first principle thinking." This assertion highlights the value of his book as a practical guide for designing and improving cybersecurity programs with a focus on first principles.

Absolute must read if you oversee any portion of a cyber security program!
Format: Paperback
I loved this book. The concepts and ideas presented are a great wake up call for an industry that is so focused on blinking light hardware and the next big technological thing...this book challenges the paradigm that you need to strip your security culture down to some very core ideas...then build a solid security program around your security first principle(s). Without that core idea, you're just throwing away money on tools that may not actually be addressing your root needs. Great read for anyone looking to rethink their security program, security culture, and security spend. BRAVO!

Context, Strategies and Wisdom in a single package
Format: Kindle
This was my first book I have read by this particular author. I had spent some time looking for a comphrensive approach to Cyber Security and found many other texts to be lacking. Certain aspects are well documented, but no single source that brought it all together. This is exactly what First Principles brings to the table. As a practicioner that looks for better ways to formulate the objectives of SecOps Use Cases I have found the methods presented in this book to be immensely helpful. I have also given copies aways as a gifts to students who are just entering the field as this is by far the best intro to the long history of Cyber Security that combines the best direction for the future. The historical context that the author brings through first hand experience is beyond a treasure trove. It has been said many times in cheezy ads, but honestly, if you only read one book on Cyber Security make it this one.

Every cybersecurity professional should read this book, probably twice
Format: Audiobook
This is the Phoenix Project for cybersecurity professionals. Every chapter of this book brought clarity and a new perspective from the way industry approaches aspects of cybersecurity. The book won’t be all things to everyone, nor is it perfect, but its the single most practical and effective approach to cybersecurity I’ve found. In a time where IT is excruciatingly complex and securing environments seems like an impossible task, this has been invaluable and has affected how I think about the future. Im not associated with the author in any way. Im just in a leadership role facing these challenges every day and I think this book may some day become mandatory reading in the field.
