当您参加测验时,就会出现答案和解释。
- What can anomaly-based AI add to signature matching when previously unseen behavior appears?
- It can flag deviations from learned normal traffic for investigation, without guaranteeing detection of every new attack
- It can prove a deviation is malicious without review
- It can identify every attacker by name
- It can replace all security monitoring
- 基于异常的检测通常如何识别威胁?
- 通过匹配已知病毒特征的数据库
- 通过学习正常行为并标记偏离行为
- 通过阻止所有加密流量
- 通过要求用户确认每个连接
- 自动编码器如何帮助检测异常网络流量?
- 为了安全起见,它对流量进行加密
- 它会自动删除可疑数据包
- 新交通信号的高重建误差表明异常
- 它统计在线用户数
- 人工智能入侵检测系统面临的主要实际挑战是什么?
- 网络太安静而无法监控
- 缺乏任何网络流量可供分析
- 攻击太容易编写签名
- 误报过多导致警觉疲劳
- 为什么训练入侵检测模型时要关注类别不平衡?
- 因为与正常流量相比,攻击很少见
- 因为用户类别太多
- 因为网络带宽不均
- 因为所有流量都是恶意的
- 以下是传统的基于签名的入侵检测工具的示例?
- Photoshop
- 鼻息
- Excel
- 阿尔法折叠
- What is the main difference between supervised intrusion classification and anomaly detection in the guide?
- Supervised models use no labels
- Anomaly detection requires every attack type to be labeled
- Supervised models learn from labeled attack examples; anomaly models can learn a normal-traffic baseline
- Both methods only examine packet payload text
- Which traffic information can be used as model features in an intrusion detector?
- Only the user’s password
- Only the final alert color
- The model’s GPU temperature
- Packet sizes, connection durations, protocols and flow statistics
