What challenges should you anticipate during SQL database migration?
SQL database migration can pose several challenges, such as data integrity issues, schema disparities between databases, potential downtime during migration, and ensuring compatibility with applications that rely on the database structure. Thorough planning, testing, and backup strategies are crucial to address these challenges effectively.

How do you use git hooks to enforce code quality and security standards?
Git hooks can be used to enforce code quality and security standards by running incremental or pre-commit checks. This could include running linting tools to check for code style consistency, running unit tests or other automated tests (such as selenium tests), or running security analysis tools to check for coding errors and potential vulnerabilities. Additionally, code reviews could be automated using pre-commit or commit-msg hooks. In addition to running automated checks, developers can also be required to sign-off on changes using a pre-commit hook, ensuring all changes are being reviewed and verified before being pushed to production."

How do you keep your HTML code maintainable and scalable for mobile web projects?
1. Use meaningful HTML element names that are easily readable and correspond to their content. 2. Separate structure from presentation by using CSS and JavaScript for styling and scripting. 3. Use responsive design practices to ensure that elements display correctly on different devices and screen sizes. 4. Optionally use frameworks like Bootstrap or Foundation to aid in creating more responsive projects. 5. Use media queries to adjust the size, position and display of elements depending on the device. 6. Use progressive enhancement by building for the lowest common denominator first and then adding additional features for more capable devices and browsers. — GPT

APCO International
[New Webinar] Reclassification Update: OMB Requests Input for SOC Revision. 7/17 at 2 pm ET. Today OMB announced the beginning of a multi-year process to revise the Standard Occupational Classification. Through this process, OMB will consider whether to change the classification of public safety telecommunicators from the administrative/clerical category to the category for Protective Service Occupations. Join us on July 17 for a webinar to explain APCO’s strategy for providing input to OMB, how this effort relates to the 9-1-1 SAVES Act and what you can do to help ensure that OMB finally corrects this outdated classification. https://lnkd.in/ekhmW5am

📣 CMMC Program Final Rule Published 📣 The final program rule for the Cybersecurity Maturity Model Certification (CMMC) Program was published in the Federal Register recently. The key takeaways include: -There are 110 identifiable and applicable security requirements specified in the new NIST SP 800-171. -Firms in the DoD supply chain are now required to provide adequate security on all contractor information systems. For example, defense contractors must confirm that any Cloud Service Providers (CSPs) used by the contractor to handle CUI meet Federal Risk and Authorization Management Program (FedRAMP) Moderate Baseline or the equivalent requirements. It also requires defense contractors to flow down all the requirements to their subcontractors who process, store, or transmit CUI. -NIST SP 800-171 has 3 levels of certification. Level 1, which is self-certified. Level 2 now has 2 separate classifications for certification including a self-certification option and a C3PAO option. For you Star Wars buffs, that is not a typo. It stands for CMMC 3rd Party Assessment Organizations. These are similar to ISO or SOC2 compliance audit agencies. The final level, Level 3 will require DoD certification. -Understanding your contractual requirements based on your defense partnership will mandate the level of certification required, and your obligations to the security, management and accountability your organization will require. Full Ruling here: https://hubs.ly/Q02Wk45N0 With risks and requirements changing quickly, it's hard to know how to ensure your compliance. SkyTerra is here to help, book a meeting with our team to learn if these new rules affect your compliance: https://hubs.ly/Q02Wk2qj0

Query
😖 SOC Analyst #1: Tell me again, why don’t we store all of the observability and network logging data in the data lake? 😇 SOC Analyst #2: Well, that would be a lot of data to keep indefinitely! 🤦 SOC Analyst #1: Uh, yeah, duh. The IT Ops team has it though, it’s inside of Amazon OpenSearch Service. 😨 SOC Analyst #2: Don’t you need to know Lucene to get at the data? 🤓 SOC Analyst #3: Actually, I am pretty sure it is a domain specific language… 😆 SOC Manager: You’re both right, it can use either, or a graphical interface. 😠 SOC Analyst #1: Okay, that’s well and good, but we got off the SIEM and moved to the data lake and I feel we’re still missing stuff. I thought cheap storage was the reason to get off of the old SIEM?! 🤓 SOC Manager: Well, those things tend to equal out, we also have to be careful with our compute charges. 🤑 SOC Analyst #3: They always get you! 😮💨 SOC Analyst #1: Alright, fine, I’m here to do SecOps not to do FinOps…even if IT does give us access, I don’t miss having to search across a bunch of different indices and learn another query language. Ain’t no one got time for that! Any chance https://query.ai can help us dodge that bullet again? 😤 SOC Analyst #2: Hold on. [TYPES FURIOUSLY] Yes! They are working on an Amazon OpenSearch Service integration right now! No Lucene, no DSL, no one-index-at-a-time – just like they do it for our lake and our other tools! 😀 SOC Manager: Yes…says they will handle all of the query translation, and normalize the data in OCSF like everything else, so we can reuse a lot of our playbooks and automation content. 😍 SOC Analyst #1: LFG! I love OpenSearch Service and Query together. Nothing is beyond our reach! 😎 SOC Analyst #2: Based.

Query
🙄 SOC Analyst 1: Dude. I hate how fast we close acquisitions these days. 🤨 SOC Analyst 2: Why? What seems to be the problem? 😤 SOC Analyst 1: Well, the last three companies we bought all had Carbon Black Cloud Enterprise EDR. So, when I get these CISA alerts about indicators, I have to check three separate platforms in three different organizations for the indicators. 😎 SOC Analyst 2: Not anymore! I fixed that. 🧐 SOC Analyst 1: Oh, did we merge them all into one platform? 🧠 SOC Analyst 2: LOL…no. Query released an integration for Carbon Black, so now one Query search will cover all three platforms, plus all the other integrations we have set up — Splunk, CrowdStrike, etc. 🤯 SOC Analyst 1: YES! That is going to really reduce the time it takes me to search across all the platforms, AND we didn’t have to move all of this data into our SIEM to do it — we could leave it where it is! Wow, think of what I can do with all of this free time! 🤓 SOC Manager: Did someone say they had free time? —-------------------------------- Read more: https://hubs.li/Q02Ct4P80 #carbonblack #edr #federatedsearch
