Free CISA/CISSP Study Threads
A high‑engagement X thread aggregated free CISA and CISSP study resources with direct links to ISC2 and ISACA, while another popular post mapped a cybersecurity career ladder from CompTIA Security+ up to CISSP and linked free Professor Messer videos. Both posts were framed as low‑cost, exam‑prep gateways. (x.com/DivyanshT91162/status/2045373934573670415, x.com/Bitcoin_Teej/status/2044777934406156389)
Two widely shared X posts are steering cybersecurity learners toward free study links for the Certified Information Systems Auditor and Certified Information Systems Security Professional exams. (x.com) One post compiled CISA and CISSP prep links and pointed readers to official exam pages from ISACA and ISC2, the two organizations that run those certifications. Another laid out a career ladder from CompTIA Security+ to CISSP and linked free Professor Messer training videos. (x.com, x.com) CISA is an audit credential from ISACA, and its current exam content outline is organized into five domains. ISACA said an updated CISA exam took effect on August 1, 2024, after a job-practice review tied to changes in technology and IT audit work. (isaca.org, isaca.org) CISSP is a security certification from ISC2 aimed at experienced practitioners, managers, and executives. ISC2 says the exam covers eight domains, uses computerized adaptive testing, runs three hours, and includes 100 to 150 questions. (isc2.org, isc2.org) The appeal of those threads is cost: the core exam blueprints are public, and both certifying bodies publish free guidance before candidates buy courses or question banks. ISC2 hosts exam outlines and self-study resource pages, while ISACA offers a free CISA practice quiz and downloadable candidate guides. (isc2.org, isc2.org, isaca.org, isaca.org) The limits are also clear on the official sites. ISACA’s main CISA prep page centers paid review courses and question databases, and ISC2’s CISSP prep pages promote official training alongside self-study tools. (isaca.org, isaca.org, isc2.org) Both certifications also require experience beyond passing a test. ISC2 says CISSP candidates need five years of cumulative paid work in at least two of the eight domains, while ISACA says CISA applicants need five years of professional auditing, control, or security experience and have five years after passing to apply for certification. (isc2.org, isaca.org) That is why “free study thread” posts travel so far on X: they lower the cost of starting, but they do not change the bar for earning the credential. The easiest entry point is still the same one those threads linked first — the official exam outline. (x.com, isc2.org, isaca.org)
