挑战
保护文件服务器上存储的不同类型的机密数据。检测可能导致违规的异常活动。加快事件和运营问题的调查和补救。
解决方案
Alex 使用 Netwrix Auditor 来了解行为异常并减轻勒索软件威胁。他收到有关可能是安全事件迹象的活动的警报,例如工作时间外登录、多次登录失败、权限更改以及非所有者邮箱访问事件。他每天都会审查用户的风险评分,以识别高风险帐户,并在安全漏洞发生之前采取行动。 Netwrix Auditor 还通过提供交互式搜索和实时报告来帮助优化调查。
运营影响
  • The implementation of the Netwrix Auditor has significantly improved the security posture of Insight Credit Union. The solution has provided visibility into anomalous behavior, enabling the credit union to detect potential security incidents in their early stages. The alerts on mass data removal or modification and excessive failed access attempts have been instrumental in mitigating ransomware attacks. Additionally, the solution has optimized investigations, making it easier to investigate operational issues such as lost files or a user’s inability to log in to certain applications. The state-in-time reports have also been beneficial, enabling the comparison of current and past system configurations.
数量效益
  • Fast detection of abnormal activity and ransomware within a couple of minutes
  • Prompt investigation and remediation of issues
  • Daily review of users’ risk scores to identify high-risk accounts
