Conferences & Events
4 entriesMajor security events.
41Gartner Security & Risk Management SummitThe original page listed roughly 30 links under alphabetical sub-headings (A–E, F–J, K–O, P–T, U–Z). On review, nearly all of them turned out to be unrelated to IT security — apparent keyword collisions and stray indexing rather than curated resources. Most strikingly, the entire "K, L, M, N, O" group consisted of nine links about (an NCD bond listing, airline reviews, a Mastercard review, a breastfeeding-policy news story), evidently swept in by the "K–O" label rather than any security relevance. The rest of the list included Medicare plan FAQs, a food-security agriculture paper, a real-estate listing, a state bar association newsletter, visa-policy news, university A–Z site indexes, and a portfolio-return calculator — none on-topic for IT security. One entry, a since-lapsed 2020 privacy conference listing, was also removed as stale. Only the item below was both live and genuinely on-topic, so it was kept; everything else was removed rather than carried forward as noise.

Frequently Asked Questions
What is IT security?
IT security is the practice of protecting information systems, networks, applications and data from unauthorised access, attack and loss, through technology, processes and people.
Which frameworks should I start with?
The NIST Cybersecurity Framework and ISO/IEC 27001 for programme structure, CIS Controls for prioritised safeguards, MITRE ATT&CK for attacker behaviour and the OWASP Top 10 for web applications.
Where do I check known vulnerabilities?
The CVE Program and NIST NVD catalogue vulnerabilities, and the CISA Known Exploited Vulnerabilities catalogue shows which are being actively exploited.
How do this page and the Cybersecurity page differ?
This page covers frameworks, standards, resources and roundups; Cybersecurity and Security Software list tools and vendors by category.
Why is the roundup list marked as dated?
Rankings and "top companies" articles age quickly, so each should be checked for its publication year before relying on it.
