[脆弱性悪用攻撃はなぜ減らない?
\---------------](https://www.paloaltonetworks.com.au/blog/2023/09/mitigating-software-vuln-exploit/?lang=ja)

既知の脆弱性を悪用したサイバー攻撃や、そうした攻撃から生じたセキュリティインシデントの報告を目にすることが、昨今まったくめずらしくなくなってきました。「既知の脆弱性なんだから対策すればすむ話では?」と片付けたくなる気持ちも確かにわかるのですが、じつは「脆弱性対策のためにパッチを当ててください」は「言うは易く行うは難し」の典型で、現場側にそれができない相応の事情があることも少なくありません。しかも、やれデジタルトランスフォーメーションだ、デジタライゼーションだ、とソフトウェアの役割の拡大が進むばかりとくれば、それらのソフトウェアを稼働させているシステムや機器がいったいどこにどれだけあるのか、ぜんぶ社内で把握して管理するのも大変です。これらの要因があいまっ...

## [AIを利用した早期発見能力の構築](https://www.paloaltonetworks.com.au/blog/2023/07/necessary-for-anomly-detection/?lang=ja)

2023年上半期もたくさんのランサムウェアや情報漏洩インシデントが国内で報告されました。攻撃者は侵入すると見つからないよう慎重に行動し、できる限り短い時間で目的を達成しようとします。防御側は攻撃者による疑わしい振る舞いを早期に発見できる能力を持つ必要があります。
