Explore threat informed defense in cyber intelligence by identifying the organization's mission, threat actors, their motivations, and TTPs, guiding detection and protection with a focused soc approach.

Learn how tactics, techniques, and procedures describe threat actor behavior from high-level objectives to detailed actions, including reconnaissance, scanning, and vulnerability scanning procedures.

Differentiate IOCs and IOAs to distinguish evidence of compromise from attacker intent; IOCs cover files and domains, IOAs cover threat actor behavior.

In vulnerability management, the pyramid of pain shows how attackers change indicators from hashes and IP addresses to TTPs, emphasizing detecting TTPs to impede adversaries.

Explore cyber threat intelligence sources across enterprise tools, open-source intel, and social media to gather IOCs, IOAs, and TTPs for vulnerability management.

Cloud computing enables on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service, allowing fast provisioning and scalable resources. These properties support pay-for-use, performance, and location-independent deployment.

Define public, private, hybrid, and multi-cloud environments and identify Azure, AWS, and GCP as public clouds, with Azure Stack, AWS Outposts, and Google Anthos enabling private or hybrid deployments.

Explore Azure global backbone details, including data centers, regional expansion, fiber and subsea connectivity, edge sites, network partners, and extensive peering, all designed for performance, fault tolerance, and disaster recovery.

Explore shared responsibility across on premises to IaaS, PaaS, and SaaS in Azure, AWS, and GCP, mapping customer duties such as operating system patching, network, identities, and data.

Master the Azure resource hierarchy by organizing resources into management groups, subscriptions, and resource groups, based on location, department, criticality, or lifecycle, to improve security and governance.

Explore Azure subscription types such as free, student, pay-as-you-go, and enterprise agreements, with emphasis on using the free option for demos in vulnerability management.

Demystify how Entra ID tenants and Azure subscriptions relate: identities in the Entra ID tenant access resources in subscriptions and resource groups.

Zero trust is a security strategy that verifies explicitly, enforces just-in-time access with least privilege, and assumes breach to minimize blast radius through network and identity segmentation.

Explore the Microsoft security cosmos for cloud security, SOC, and CTI, highlighting Defender XDR, Defender for Identity, Defender for Endpoint, Defender for Cloud Apps, and Defender for Cloud.

Defend a classic cyber kill chain by mapping threats from phishing to data exfiltration. Leverage Defender for Office, Defender for Endpoint, and Copilot for security, plus XDR and Sentinel.

Identify vulnerabilities as weaknesses in information systems, security procedures, internal controls, or implementations that threat sources could exploit, including software, humans, hardware, physical controls, and CVEs.

Explore the common vulnerabilities and exposures framework and CVE IDs, including descriptions, data sources, announcements, and CVSS scoring, using CVE-2009-2935 in Chrome as an example of remote code execution vulnerability.

learn how the common vulnerability scoring system (cvss) provides a universal severity score to rank and prioritize vulnerabilities, and compare cvss v2 and v3 with asset criticality in mind.

Explore the National Vulnerability Database from NIST to research vulnerabilities using CVE and CVSS concepts. Understand the dashboard and backlog; base score, temporal score, and environmental score guide prioritization.

Explore where vulnerabilities can occur across hardware, operating system, middleware, and application layers to inform vulnerability management.

Examine zero day vulnerabilities, their time sensitivity, and disclosure options: public release, vendor notification with bug bounty, or selling on the dark market—and how disclosures trigger patches and CVE entries.

Outdated software remains one of the most common vulnerability types, despite known patches and compensating controls. Attackers exploit internet-connected, unpatched systems to enable remote code execution and privilege escalation.

Cloud misconfigurations create vulnerabilities without CVEs, as misconfigured Azure storage or AWS S3 buckets enable read or write by adversaries; vulnerability management must target cloud configuration weaknesses, not CVEs.

Exploiting vulnerable systems remotely with connectivity alone, attackers can achieve remote code execution. Compromising internet-facing Windows servers allows attackers to gain root or admin access, highlighting defense challenges.

Explore vulnerabilities across layers—application, middleware, operating system, and hardware—featuring Heartbleed, log for shell, Eternalblue, meltdown, and Spectre.

Heartbleed exposes a critical vulnerability in OpenSSL TLS/DTLS heartbeat handling, enabling remote attackers to read memory and extract private keys by overreading server responses, with a CVSS 7.5 score.

Examine the Log4Shell vulnerability, a remote code execution flaw in middleware that lets an attacker inject LDAP lookups into log messages to load and run malicious Java code.

Trace the EternalBlue zero-day from NSA discovery to Shadow Brokers theft, patch release by Microsoft, and its use in the WannaCry campaign, explaining its SMB v1 remote code execution vulnerability.

Examine the meltdown vulnerability, disclosed in 2017 and related to Spectre, which allows unauthorized data disclosure through side channels in processors using speculative execution.

Learn how vulnerability management identifies, evaluates, prioritizes, remediates, and reports vulnerabilities. Apply automated scans and manual testing, assess cvss scores, and implement patches or compensating controls.

Identify vulnerabilities at scale with automated scans across apps, OS, middleware, and hardware, balancing agent-based and agentless options, and address CVEs and misconfigurations through inventory management and manual testing.

Prioritize vulnerabilities using risk-based ranking that considers cvss, asset criticality, and compliance, while aligning with available resources and production impact to avoid disruption.

Apply patches, adjust configurations, or use mitigation techniques to remediate vulnerabilities based on type. Use compensating controls like a web application firewall when patching or configuration changes aren't feasible.

Document vulnerability details, including identified, mitigated, and outstanding issues; conduct regular stakeholder reviews to align progress; and prepare audit reports to ensure PCI-DSS and automotive compliance, reducing attack surface.
