Defend against AI-assisted attacks with practical guidance for cybersecurity and network professionals. Ten reading paths contain 20 articles each, with threat scenarios, evidence requirements, control designs and authorized validation plans. The collection includes protection for AI systems used by defenders and businesses. Behavioral evidence is kept separate from claims about an attacker's use of AI.
Build reliable agents and run language models on your own infrastructure. Explore 160 AI Agents techniques and 140 Local LLM techniques across 15 reading paths, with 20 techniques per path. Each guide includes an implementation action, a validation exercise, platform context and official documentation for further reading.
Diagnose stale reports, late logs, slow queries and unreliable alerts. Explore 40 Power BI articles, 40 Splunk articles, 40 SQL Server articles, plus 20 each on PostgreSQL, MySQL, pipeline freshness and data quality, and alerting and observability. Each guide connects a specific symptom to evidence, a focused correction and validation.
Prepare for CCNA 200-301 v1.1 with 100 focused topics, each paired with a recall guide and an original practice exercise. Build understanding through packet tracing, subnet calculations, lab evidence, troubleshooting and spaced review. These are independent study guides; 200 is the collection size, not the number of questions on the exam.

Data Monitoring
A routine dashboard scans all indexes for a rare service. Compare scanned event volume and job duration after adding the correct index, sourcetype and time constraints.

An aggregate count hides a small group of malformed events. Compare summary results with a bounded sample of contributing raw events.

A short error spike disappears in coarse dashboard intervals. Compare the same period at several bucket sizes and label incomplete edge buckets.
Read article : Splunk: Timechart bucket interpretationData Monitoring
A report undercounts records because some events lack a grouping key. Measure key presence before aggregation and inspect malformed source records.

An ownership lookup routes new services to the wrong team. Compare lookup update time and key coverage with the service inventory.

Nested application data is indexed but a dashboard reads the wrong field path. Inspect sample payload structure and distinguish arrays from scalar objects.

A fast sample suggests there are no rare failures. Compare sampled evidence with a bounded unsampled check over the relevant incident window.

A new event field exposes customer identifiers to broad search roles. Inspect the producer schema and test who can search the field in the intended indexes.
Read article : Splunk: Sensitive data in logsData Monitoring
A search still runs when its next scheduled execution is due. Compare runtime with schedule frequency and inspect scheduler messages for skipped or delayed executions.
Read article : Splunk: Scheduled search overlapData Monitoring
A high failure count pages the team during a traffic surge even though the rate is normal. Compare failures and eligible requests in the same window and service scope.
Read article : Splunk: Alert threshold denominatorData Monitoring
One noisy host suppresses alerts for unrelated hosts. Inspect the fields used to group or suppress notifications.

Operators receive a problem alert but no clear indication of recovery. Replay an unhealthy interval followed by normal values and inspect notification lifecycle behavior.
