What Is an Immutable Backup? (opens the original)
Read excerpt
An immutable backup is a protected copy of data that cannot be modified or deleted during a defined retention period, even by accounts that normally possess administrative privileges. Certification exams may connect immutability with ransomware recovery, insider threats, retention controls, and protection against compromised backup administrators. Attackers frequently attempt to erase or encrypt recovery data before disrupting production systems, so an immutable copy can preserve a trusted resto
What Is Chain of Custody? (opens the original)
Read excerpt
Chain of custody is the documented record of how evidence was collected, identified, transferred, stored, examined, and protected from the moment it was acquired. Certification exams may ask why investigators record who handled an item, when possession changed, where it was stored, and what actions were performed. This documentation helps demonstrate that evidence presented during legal, disciplinary, or administrative proceedings is the same evidence originally collected and was not improperly
What Is Alert Fatigue? (opens the original)
Read excerpt
Alert fatigue develops when analysts or users receive so many repetitive, low-quality, or poorly prioritized notifications that important warnings become difficult to recognize and investigate. Certification exams may describe a security operations team ignoring alerts after repeated false positives and ask candidates to identify the operational problem. Common causes include overly broad detection rules, duplicate notifications, missing context, weak severity assignments, and alerts that provid
False Positives and False Negatives (opens the original)
Read excerpt
A false positive occurs when a security control reports malicious activity that is not actually present, while a false negative occurs when genuine malicious activity is missed. Certification exams may ask candidates to identify these outcomes or explain the tradeoff created when detection thresholds are adjusted. A rule that alerts on every administrative script may create excessive false positives, while a rule that requires several severe conditions may overlook a real attack. Defenders shoul
What Is an Indicator of Compromise? (opens the original)
Read excerpt
An indicator of compromise is an observable clue suggesting that malicious activity may have occurred within a system or environment. Certification exams may present a suspicious file hash, unfamiliar domain, unexpected account, altered configuration, unusual process, or unauthorized network connection and ask candidates to classify it as an indicator requiring investigation. An indicator is not automatic proof of an incident because legitimate activity may produce similar evidence, and attacker
