A comprehensive guide for implementing enterprise-grade Security Access Service Edge (SASE) architectures using Palo Alto Networks Prisma Access. This skill covers configuring ZTNA connectors, GlobalProtect agents, security policies, and device posture checks (HIP) to provide unified, cloud-delivered security, replacing traditional VPNs and maintaining zero trust principles across remote and branch offices.

This skill provides a comprehensive guide to deploying a Software-Defined Perimeter (SDP) compliant with the CSA v2.0 specification. It details implementing core zero trust mechanisms, including Single Packet Authorization (SPA) and mutual TLS (mTLS), using a controller and gateway architecture. Use this when establishing invisible, identity-centric network access (dark cloud) to harden infrastructure, enforce strict zero trust policies, or meet advanced compliance requirements.

This guide details deploying Tailscale (or self-hosted Headscale) to create a WireGuard-based zero trust mesh VPN. It establishes encrypted peer-to-peer connections between devices, eliminating the need for traditional VPN servers. Features include identity-aware Access Control Lists (ACLs), subnet routing, and secure connectivity for compliance-driven architectures. Use this when enforcing granular, identity-authenticated access control.

This guide provides comprehensive techniques for detecting Layer 2 ARP poisoning and spoofing attacks. It covers monitoring gratuitous ARP floods, tracking IP-to-MAC mapping changes, and identifying rogue devices. Techniques include deploying ARPWatch, configuring Dynamic ARP Inspection (DAI) on managed switches, and using advanced Wireshark filters or custom Python scripts for robust security monitoring and incident response.

A comprehensive guide for deploying and operationalizing Amazon GuardDuty. It provides continuous, intelligent threat detection across core AWS services including S3, EKS, and EC2 runtime monitoring. Use this skill to investigate suspicious activity, detect compromised credentials, or build automated incident response playbooks using EventBridge and Lambda for proactive security.

This guide details comprehensive detection methods for DCSync attacks (MITRE T1003.006) in Active Directory. Attackers abuse legitimate directory replication protocols to extract sensitive password hashes. Detection relies on auditing Windows Event ID 4662 for unauthorized access attempts to critical Directory Service GUIDs, specifically flagging non-domain-controller accounts attempting replication calls. Essential for threat hunting and incident response.

A comprehensive guide for advanced threat hunting, focusing on detecting DLL side-loading and search-order hijacking (MITRE T1574). It instructs users to analyze Sysmon Event ID 7 logs, validate file signatures and hashes, and identify path anomalies to uncover APT persistence mechanisms. Essential for incident response and proactive threat detection in enterprise environments.

This tool detects critical anomalies in DNP3 communications used within SCADA and ICS environments. It employs deep packet inspection and machine learning to monitor for unauthorized control commands, protocol violations, firmware update attempts, and deviations from established network baselines. It is essential for securing critical infrastructure, such as energy grids and industrial control networks, and building robust anomaly-based Intrusion Detection Systems (IDS).

A comprehensive guide and analysis framework for detecting compromised Office 365 or Google Workspace email accounts. It focuses on analyzing unified audit logs and Azure AD sign-in logs to identify indicators of account takeover (ATO) or Business Email Compromise (BEC). Detection methods include monitoring impossible travel events, identifying malicious inbox rules (e.g., external forwarding or deletion rules), and analyzing suspicious Microsoft Graph API access patterns.

This guide is designed for threat hunting, helping security teams proactively detect persistent unauthorized access methods. It focuses on identifying malicious inbox/mail-flow forwarding rules that adversaries establish after a compromise to maintain access to corporate communications, often associated with Business Email Compromise (BEC) or T1114 techniques. Use during incident response and proactive security assessments.

A comprehensive guide for detecting Kerberoasting attacks by monitoring for anomalous Kerberos TGS requests (Event ID 4769). This technique targets service accounts with Service Principal Names (SPNs), which are requested offline by attackers to crack service account passwords. Use this during threat hunting or incident response to scope MITRE T1558 credential access activities in Active Directory environments.

A comprehensive guide and workflow for detecting Mimikatz and similar credential-dumping activities. It utilizes command-line pattern matching, LSASS memory access signatures, binary indicators, and in-memory analysis. Ideal for threat hunting, scoping compromises during incident response, or validating detection coverage in purple team exercises using EDR/SIEM data.
