#ISMAP
IDCFはISMAP取得の会社で、国関係のサービスにはISMAPを取得しているクラウドを使いましょうってなっているわけで、現に都道府県の利用があったわけだ。マルチクラウドはするなというガイドラインもあわせて、政府関係機関が考えてた「安全なクラウド」の基準が根元からへし折れたって感じがする。

バックアップも同時に破壊された fxtwitter.com/stcatcom/sta... という噂ですけど。管理システムとバックアップが適切に隔離されていなかったとしたら、これまた ISMAP の審査はザルってことに以下略。

IDCF クラウドって、政府情報システムのためのセキュリティ評価制度(ISMAP) www.ismap.go.jp/csm に適合しているはず www.idcf.jp/news/newsrel... なんですよね。もしも本当に EOS なハイパーバイザを使っていたのなら、ISMAP の審査はザルってことになるので以下略。

No sign IDC Frontier fell short of ISMAP. But an assessment shows requirements were met when evaluated, not that a breach can't happen. Customers still need their own backups.

IDCF Cloud, hit by ransomware this week, is registered under ISMAP, Japan's rough equivalent of FedRAMP.

The rules require a preliminary incident report within ~3 working days. Listing is suspended only if the provider fails to report, so the attack alone doesn't remove it.

IDCF Cloud is one of Japan's main domestic clouds, ISMAP-listed for government use. Which sites are confirmed affected, what's only claimed, and why same-provider snapshots aren't backups.

Gosh, I remember using ismap to make very low fidelity clickable prototypes back in the early-ish 2000s from edited screenshots using my treasured copy of Photoshop 6 (last one before annual subscriptions). Still have Photoshop 6, haven’t done ismap in 20 years.

Esoteric HTML - ismap vs CSS
The HTML specification is old and, while there is beauty in longevity, there's an inevitable build-up of boondoggles and baggage. Some elements like have sadly been consigned to the dustbin of history - but there are still vestigial attributes just waiting to trip up the unwary. If you're young, you may never have heard of Image Maps. Back in the bad-old-days, there weren't many good…
