Рекомендации по использованию AI при разработке открытого кода Правозащитная организация Software Freedom Conservancy (SFC), предоставляющая юридическую защиту свободным проектам и отстаивающая необходимость соблюдения лицензии GPL, подготовила список рекомендаций по использованию AI-систем на базе генеративных моделей машинного обучения при подготовке кода для открытых проектов. Рекомендации касаются юридических, этических и социальных особенностей применения AI при разработке кода под открытыми и свободными лицензиями, а также отражают взаимодействие разработчиков c AI, учитывая противоположные мнения в сообществе о допустимости применения AI в открытых проектах. Рекомендации пытаются свести к минимуму проблемы, которые могут возникнуть из-за использования AI-систем по своей инициативе или по требованию работодателя. 👉@sysadminoff https://www.opennet.ru/opennews/art.shtml?num=65754

Managing Microsoft Defender configuration drift to prevent silent endpoint exposure Microsoft Defender configuration drift occurs when endpoint security settings gradually diverge from their intended hardened state due to troubleshooting or policy conflicts. This divergence often happens silently because Defender does not generate telemetry or XDR alerts when enforcement settings, such as Attack Surface Reduction rules, are modified. Standard monitoring tools frequently report these devices as compliant even when their actual protection posture has been significantly weakened.
