Editorial principles

Editorial and advertising principles · Updated: 20 September 2026

InfoSec 3001 is operated by 3001 LABS and edited by boseok lee. Our goal is to connect computer foundations with programming, defensive understanding and authorized security practice.

What a lesson should provide

A useful lesson states its prerequisites, explains the concept, presents examples, describes what to observe, and provides exercises and completion criteria. Check your own operating system, privileges and tool version before running a command. A command completing successfully is different from proving that its interpretation is correct.

What has been verified

A page’s content update date records its manuscript revision; it does not certify every example. A practice record names the environment, date, checks and limitations of that particular run. Historical measurements, illustrative output and new observations must be distinguished. Steps 1–11 have earlier Windows PowerShell 5.1 and PowerShell 7 practice records. On 20 September 2026 their current code blocks were compared with those records. This is not a claim that the whole curriculum has been rerun or independently certified.

Original explanations, sources and translations

Lessons should add explanations, observations and troubleshooting that help readers use the material. Official documentation supports tool and protocol descriptions. Sources, third-party images and exercises retain their owners’ rights; linking a source does not grant permission to republish it. Illustrative data and scenarios are not real incident evidence. Korean and English examples should preserve the same commands, prerequisites and cautions. Report discrepancies so both versions can be checked.

Authorized practice and defensive outcomes

Use only an isolated lab you own or a training platform that explicitly authorizes the exercise. Authorization must cover the system, accounts, techniques and period of use. Do not use public services, other people’s accounts, real leaked credentials or workplace networks as convenient targets. Keep lab listeners on loopback where the lesson uses one computer. Do not disable organizational safeguards, and stop the exercise if an unexpected target or real personal data appears. Pair observations with detection, mitigation and cleanup. Malware concept lessons do not require downloading or executing malware.

Corrections and reports

Use the issue report form for a lesson URL, step number, relevant passage, environment and expected versus observed behavior. Do not include secrets or private files. For rights questions or a response, contact hi@3001.co.kr. Confirmed problems are corrected in the relevant explanation, example and language version. A report alone is not proof of an error.

Advertising is separate from learning

Clicking advertisements, installing advertised software or buying a product is never a completion requirement. Functional screens and policy pages are excluded from ads. Selected lesson manuscripts are allowed only after a recorded review; manuscript changes invalidate that selection unless the revised content is explicitly reviewed again. This internal selection does not imply Google has approved the site or certified the lesson. Sensitive security lessons remain excluded while additional review is needed.
