What to know about parsing JSON: JSON parsing converts strings into structured objects your code can work with. It supports data interchange, reduces injection risk by enforcing expected formats, and makes logs far easier to search. The blog covers readability techniques, partial parsing, language-specific methods, and JSON logging best practices like flattening structures and keeping data types uniform per field. https://graylog.org/post/what-to-know-parsing-json/ #JSON #Logging #InfoSec #SysA...

India&#39;s DPDPA sets strict rules for any organization processing personal data of Indian residents, think GDPR, but with its own unique twist. Consent, access rights, breach notification within 72 hours, and enhanced obligations for &quot;Significant Data Fiduciaries.&quot; We break it all down, including what security safeguards are required under the Rules. https://graylog.org/post/indias-data-protection-law-the-digital-personal-data-protection-act/ #DPDPA #DataPrivacy #InfoS...

Logging Windows events isn&#39;t enough. You need to know which categories actually matter. Logon events, privilege use, account lifecycle, scheduled task abuse, audit policy changes, AD trust modifications, and AV telemetry each map to real attacker techniques. Gap in any one of them = blind spot an adversary will exploit. Is your log management platform covering all the bases? https://graylog.org/post/critical-windows-event-ids-to-monitor/ #InfoSec #CyberSecurity #BlueTeam #SIEM #Wind...

A Sankey chart scales each link by the volume it carries, so an unusual flow between hosts stands out instead of hiding in a log table. Here’s how security teams use them for network traffic, authentication paths, attack paths, and log routing. https://graylog.org/post/how-security-teams-can-use-sankey-charts/

PHP2Shell (CVE-2026-109618, CVE-2026-109619) is unauthenticated remote code execution in PHP core, and the default configuration is exposed. Parsing happens before your application runs, so route-scoped WAF rules never see it. Patch to 8.5.12, 8.4.27, 8.3.36 or 8.2.35. Then hunt. Attacks were reported before the patch shipped, so run these four Graylog searches across your full retention period, not just from today. https://graylog.org/post/detecting-php2shell-cves-with-graylog/

Graylog 7.2 introduces Graylog Collector, a native log shipper you install once and manage entirely from the Graylog interface. Collectors join fleets through enrollment tokens. Sources for files, journald, Windows Event Log, and macOS unified logging are defined centrally and pushed live to every host in the fleet, with no restarts. Mixed OS fleets get the right sources for each host automatically. Our latest Graylog Labs post explains how it works and walks through installation and trouble...

Audit trails need two things working together: integrity (nothing alters the record) and confidentiality (only authorized people see it). Miss either one and the trail stops being useful evidence.

Cloud-native APM comes with challenges monolithic systems didn&#39;t have: ephemeral infrastructure, tool sprawl, telemetry costs outpacing budget, and alert fatigue that buries the signal that matters.

Suricata produces rich network telemetry, alerts, anomalies, flow data, DNS, TLS, SSH, Kerberos, and more, but raw EVE JSON isn&#39;t investigation ready on its own. The Suricata IDS/IPS Content Pack for Graylog parses, enriches, and maps that data to the Graylog Information Model, with a dashboard built in. Setup covers Filebeat via Sidecar or syslog forwarding.

Data pipeline management for security and observability comes down to five stages: collection, processing, routing, storage, and retrieval. Get them right and you control ingestion costs, cut alert fatigue with cleaner data, meet retention requirements for frameworks like SOC 2 and PCI DSS, and keep archived logs searchable when you need them.

Configuration drift happens quietly. A manual fix here, a hotfix there, a deployment that misses part of the fleet. Over time the gap between documented baseline and actual state grows until it surfaces as a security gap, a compliance failure, or an outage. This new blog post covers the root causes and the practices that catch drift early, including baselining, continuous monitoring, and centralized logging. https://graylog.org/post/recognizing-and-mitigating-configuration-drift-risks/

Storing every log forever? That&#39;s not security — that&#39;s a storage bill. Effective log retention means tiering your data: hot for active monitoring, warm for periodic audits, cold for long-term compliance. The right strategy keeps the signal, cuts the noise, and scales without breaking your budget. New guide on building a cost-effective log retention strategy: https://graylog.org/post/how-to-build-a-cost-effective-log-retention-strategy/ #InfoSec #LogManagement #SIEM #Complian...

SaaS-only SIEM fails the moment it assumes connectivity that doesn&#39;t exist. Air-gapped military networks. OT-isolated pipelines and power grids. Government research enclaves. Hard data residency mandates across the EU, GCC, and beyond. In each case the issue isn&#39;t the product — it&#39;s the architecture.

Singapore&#39;s CCoP 2.0 isn&#39;t a once-a-year audit exercise. It mandates continuous monitoring, behavioral anomaly detection, and integrated IT/OT coverage for good reason. In July 2025, a Chinese-linked APT group was found operating inside all four of Singapore&#39;s major telcos, using techniques that signature-based detection misses entirely. New Graylog blog breaks down what CCoP 2.0 actually requires and includes six indicators to assess your detection posture before your...

The 2026 World Cup is the most complex digital event in history, and the threat window it creates isn&#39;t limited to FIFA. Gaming platforms, payment processors, broadcasters, hospitality providers: all in scope. A 30-second log delay means a stolen credential has 30 seconds of operational freedom before anyone sees the first signal. That&#39;s not a performance issue. That&#39;s a security gap.
