A.  

An insider threat compromised the service account to delete sensitive data.

B.  

External attackers gained access and are exfiltrating data stealthily.

C.  

A ransomware attack is underway, encrypting files and deleting originals.

D.  

A misconfigured backup process malfunctioned, causing unexpected file changes.

A.  

Rule-based detection is effective with fewer false positives, and behavioral adapts over time.

B.  

Behavioral detection is easier to deploy without rules, and rule-based needs historical data.

C.  

Behavioral detection is adaptive to deviations, and rule-based detection uses static rules.

D.  

Rule-based detection excels at APT hunts with updates, and behavioral focuses on anomalies.

A.  

A policy violation is active for host 10.10.101.24.

B.  

A host on the network is sending a DDoS attack to another inside host.

C.  

There are two active data exfiltration alerts.

D.  

A policy violation is active for host 10.201.3.149.

A.  

A false negative is alerting for an XSS attack. An engineer investigates the alert and discovers that an XSS attack happened A false positive is when an XSS attack happens and no alert is raised

B.  

A false negative is a legitimate attack triggering a brute-force alert. An engineer investigates the alert and finds out someone intended to break into the system A false positive is when no alert and no attack is occurring

C.  

A false positive is an event alerting for a brute-force attack An engineer investigates the alert and discovers that a legitimate user entered the wrong credential several times A false negative is when a threat actor tries to brute-force attack a system and no alert is raised.

D.  

A false positive is an event alerting for an SQL injection attack An engineer investigates the alert and discovers that an attack attempt was blocked by IPS A false negative is when the attack gets detected but succeeds and results in a breach.

A.  

Statistical detection involves the evaluation of events, and rule-based detection requires an evaluated set of events to function.

B.  

Statistical detection defines legitimate data over time, and rule-based detection works on a predefined set of rules

D.  

legitimate data over a period of time, and statistical detection works on a predefined set of rules
