SITA 是一个风险与问责案例：其 2021 年旅客服务系统数据安全事件显示，可见航空公司品牌背后的供应商如何成为乘客与常旅客证据的实际保管者。公开记录对于乘客、忠诚度会员、航空公司、联盟、监管机构及客服团队至关重要——他们需要证明航空公司租户数据已确定范围、得到遏制、通知并修复，且未使一家航空 IT 提供商成为共享盲点。
SITA is a risk and accountability case because its 2021 Passenger Service System data-security incident showed how a supplier behind visible airline brands can become the practical custodian of passenger and frequent-flyer evidence. The public record matters for passengers, loyalty-program members, airlines, alliances, regulators, and customer-service teams who needed proof that airline-tenant data was scoped, contained, notified, and repaired without turning one aviation IT provider into a shared blind spot.
