CISSP

⚠️ **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)

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.

With few exceptions, no shows or cancelations within 1 week of the event will not be eligible for future CMG Gives Back events.

...and speaking of breakthrough roles: who can forget the first time we saw Tom Cruise singing Bob Seeger in his underwear? Often considered an updated 1983 version of The Graduate, the movie sparkles with memorable lines and original music. I only regret that I was never told that "Princeton could use someone like Bob..." See the movie first and join us for some "Cruisin'"

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way.

It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

In *City Lights*, Chaplin's Little Tramp meets a blind girl selling flowers who mistakes him for a wealthy man. When he learns that an operation may restore her sight, he sets off to earn the money she needs to have the surgery. He also befriends an alcoholic millionaire who only recognizes him when he is drunk. When the blind girl and her grandmother fall behind in the rent and face eviction, he tries working and even enters a boxing competition to raise the money they need. Regarded as Chaplin's masterpiece, *City Lights* has been ranked on more than seventeen "100 greatest movies of all time" lists. Orson Welles cited it as his favorite picture. *City Lights* is available for streaming on Amazon Prime, Hulu, HBOMax, Tubi and PlutoTV. The Columbus Library lists three copies on blu-ray and eight copies on DVD. Watch the movie on your own, then join us upstairs at East Market to discuss the film.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!
