Systèmes de sécurité

**For ages 13 and above.** Systema is a Russian Martial Art founded by the late Colonel Mikhail Ryabko and Vladimir Vasiliev. Systema was designed to develop individuals in a combative style which upholds the intrinsic value of all human life. This is why it is non-destructive – even of one’s enemies. Through the use of simple exercises, breathing techniques and massage work, Systema helps you to build a strong mind and body. Here is what you can expect: **Warm ups** Class begins with warming up each of the systems of the body – from the breathing, muscular and nervous system, each component needs to be properly engaged. **Thematic studies** Fetching from a huge pool of drills and sometimes even crafting specialized ones, our instructors format a logical progression of the concept being shared. Depending on the ability of the class, the drills are modified to be at the optimal level for learning, with suitable modifications given to students based on their individual performance. **Application of concepts** After the thematic studies, some time is given for the students to apply the training – the intensity is decided upon by the students under the supervision of the instructor. At times, the instructor will request for the students to push themselves, while at other times they are there to taper in the sparring to a productive level. **Cool downs** The cooldowns are usually done in a way both the help the class recover from the higher intensity application section as well as to revisit the concepts again in a calmer manner. This helps to ensure everyone is reminded of the key points. Sometimes we do a little massage. **Training circles** At the end of every training session, we circle up to share a few words about the training. This tradition was handed to us from our founders and is an integral part of our training. ### **Address** Lor 23 Geylang, #03-05 37, Singapore 388371 ### **Schedule** Saturdays 10AM - 12PM ### **Booking Information** * Please contact **98225900** to find out how to book this class. * The instructor will reach out to you once you've booked the class.

⚠️ **REGISTRATION IS REQUIRED VIA [LUMA](https://luma.com/7adqd4e9)** ⚠️ **ABSTRACT** SHELLgym is the regular cybersecurity workout you have been looking for! Whether you're just starting out and need some exercises, studying for a cert (hint: OSCP), looking at CTF challenges, or developing something cybersecurity-related (maybe your own automated tools?), SHELLgym aims to help you progress in picking up practical cybersecurity knowledge and skills. Come and go as you please, work on your own stuff with like-minded individuals, or just have fun during the workout! **AGENDA** Getting and using shells. Finally, a topic in SHELLgym that covers shells! For this session, we'll talk about remote access, from exploits versus payloads, to simple persistency. Then, we'll do some triaging and threat hunting to detect such shells in our environment. The session will roughly follow this sequence: 1\. Remote access: bind/reverse shells 2\. A simple\, traditional killchain from exploit to payload to persistency 3\. Getting inspired by MITRE TTPs 4\. Threat hunting **⚠️ NOTE** Requirements: a computer, so that you can connect to the network, administer your shells, and enjoy a more interactive hands-on experience. **VIRTUAL SHELLgyms in APRIL** (by request) Hosted on Discord, do approach KK or the Div0 Crew for access ! **TRAINER** **KK "Jim" Tan — Founder, counterShell** As a mid-careerist convert to cybersecurity, **Jim** picked up his practical skills through getting OSCP certified and by participating in a variety of CTFs. In his career at CSIT, he performed a variety of red-teaming and vulnerability research roles and established the Cyber Training School at CSIT as the Lead Instructor. Besides the OSCP certification, Jim is also OSCE and OSEE certified, and has a Bachelor's degree in Social Science (Psychology). He now sees psychology as a field of study where you fuzz humans until they produce unexpected behaviour. **SPONSORS** * VENUE SPONSOR: [CyberSG TIG Collaboration Centre](https://www.linkedin.com/company/cybersg-tig-collaboration-centre) **IMPORTANT NOTICES** * Code of Conduct: [https://www.div0.sg/code-of-conduct](https://www.div0.sg/code-of-conduct) * Terms of Use & Disclaimer Notice: [https://www.div0.sg/terms-of-use-disclaimer-notice](https://www.div0.sg/terms-of-use-disclaimer-notice)

This Easter, step into a weekend of profound spiritual significance unlike any other! Join Master Daniel Gorgonia for the Easter Spiritual Awakening Weekend — two extraordinary days held on 4 & 5 April 2026 (Sat & Sun), where ancient wisdom traditions converge in alignment on the exact days of Easter. On Saturday, 4th April, immerse yourself in the wisdom of Buddhism in Grandmaster Choa Kok Sui’s Inner Teachings of Buddhism Revealed — timed as a powerful preparation for the coming Wesak Festival in early May this year. In this course, you will uncover the Secrets of the Three Jewels, gain deep insight into the Four Noble Truths and the Eightfold Path, and discover the root causes of life’s suffering — along with step-by-step techniques to overcome them. You will get to explore higher dimensions of Vipassana and Illumination, and learn to cultivate the Buddha Nature, Higher Buddha, and Adi Buddha Natures within yourself. You will also learn the transformative practice of Spiritual Detachment — allowing you to embody genuine compassion for all, while remaining anchored and unshaken by the emotional and social turbulence of the world around you. These teachings and practices will enrich your preparation leading up to Wesak - positioning yourself to receive and be a channel at the peak of the meditation. On Sunday, 5th April — Easter Sunday itself — experience one of the most powerful alignments possible: learning, healing, and awakening on the very day that celebrates the Resurrection of Christ! Easter Sunday carries an immense outpouring of divine grace, renewal, and transformative light — and on this sacred day, you will go beyond the familiar surface of Christian teachings into their inner mysteries. Discover the Lord’s Prayer as an advanced method of chakra activation, the Secret Purification Rituals of the Essenes, and the hidden teachings behind Baptism by Fire, Water, Air, and the Holy Spirit. Explore the deeper spiritual meaning of the Trinity, the inner significance of Christ washing the feet of the apostles, and the formula for becoming One with your Higher Self through the verse of the Camel and the Eye of the Needle. Also, delve into the relationship between your Spiritual Anatomy and the Inverted Tree of Life’s Twelve Fruits as revealed in Revelations, and understand the true meaning of Transfiguration and the Pentecostal Fire. To walk this path of inner revelation on Easter Sunday itself, is to allow the energy of the Resurrection Day to be experienced more profoundly, and more transformatively.

**Connected Westerville Night of Networking** *April Edition: The Introduction Economy* You've been to the networking events. You've done the small talk. Collected the cards. Forgotten the names. And walked out feeling like you just wasted two hours of your life. The problem isn't you. It's the format. Most networking events put you in a room and tell you to figure it out. So everyone defaults to elevator pitches and business talk, and nothing real gets built. Here's the truth about networking that most people miss: Your network isn't just who you know. It's who thinks of you when they're talking to someone else. *That's* The Introduction Economy. And it only works when relationships are real. There's a reason people who come once keep coming back. It starts with seven minutes that feel nothing like networking. Then we open it up. Free networking. More conversations. More momentum. This is a room full of corporate professionals, entrepreneurs, business owners, creatives, and career builders in the Westerville and Columbus area. The mix is the magic. You might never do business with everyone you meet tonight. But someone in this room will think of *you.* **By name**. So, the next time someone needs exactly what you do, you get the recommendation. **April 14th. RSVP now.** **When:** Tuesday\, April 14th \| 6:15 PM \-\- 8:00 PM **Where:** Vineyard Community Center \| 6000 Cooper Rd\, Westerville\, OH 43081

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
