Mahipal 2fb6a9faff Rewrite 548 skill descriptions to the activation rubric

Each rewritten description now states both what the skill does (concrete
capability, named tools/artifacts) and an explicit when-to-use trigger,
improving agent discovery/activation. Grounded in each skill's own body;
changes confined to the `description` field only (bodies and all other
frontmatter untouched). Produced by a gated audit->rewrite->recheck loop
(548 -> 0 flagged) with a sampled anti-invention check (0 ungrounded).

Schema: 817/817 pass. Framework-ID gate: 0 defects.

Implementing Google Workspace Phishing Protection

Overview

Google Workspace provides advanced phishing and malware protection through the Admin Console under Apps > Google Workspace > Gmail > Safety. Key features include Enhanced Pre-Delivery Scanning that examines messages more thoroughly before they reach inboxes, attachment and link protection that scans for malware and checks against known malicious sites, and spoofing detection for domain and employee name impersonation. Google's Advanced Protection Program (APP) provides the strongest account security for high-privilege users.

When to Use

When deploying or configuring implementing google workspace phishing protection capabilities in your environment
When establishing security controls aligned to compliance requirements
When building or improving security architecture for this domain
When conducting security assessments that require this implementation

Prerequisites

Google Workspace Business Standard or higher license
Gmail Settings administrator privilege
Understanding of organizational email flow and third-party integrations
Access to Google Admin Console (admin.google.com)
DNS management access for SPF, DKIM, DMARC configuration

Workflow

Step 1: Configure Advanced Phishing Protection

Navigate to Admin Console > Apps > Google Workspace > Gmail > Safety
Enable "Protect against domain spoofing based on similar domain names"
Enable "Protect against spoofing of employee names"
Enable "Protect against inbound emails spoofing your domain"
Set action for detected spoofing: quarantine or move to spam with warning banner
Apply settings to all organizational units or specific high-risk groups

Step 2: Enable Enhanced Pre-Delivery Scanning

In Safety settings, enable "Enhanced pre-delivery message scanning"
This adds additional delay (seconds) to scan messages more thoroughly
Configure to detect phishing attempts that evade initial filters
Enable "Identify links behind shortened URLs"
Enable "Scan linked images" for image-based phishing detection

Step 3: Configure Attachment Protection

Enable "Protect against encrypted attachments from untrusted senders"
Enable "Protect against attachments with scripts from untrusted senders"
Enable "Protect against anomalous attachment types in emails"
Configure action: warn users, move to spam, or quarantine
Create exceptions for known legitimate encrypted file senders

Step 4: Enable Enhanced Safe Browsing

Navigate to Admin Console > Security > Gmail Enhanced Safe Browsing
Enable Enhanced Safe Browsing for the organization (off by default)
This provides real-time protection against phishing URLs in emails
Configure at organizational unit level for phased rollout
Monitor user feedback for false positive impact

Step 5: Enroll High-Risk Users in Advanced Protection Program

Identify high-privilege accounts: super admins, executives, finance leadership
Enroll users in Google's Advanced Protection Program (APP)
APP requires FIDO2 security keys for authentication
APP blocks third-party app access unless explicitly approved
APP provides enhanced scanning for Gmail and Drive downloads

Step 6: Configure Email Authentication

Publish SPF record: v=spf1 include:_spf.google.com ~all
Enable DKIM signing in Admin Console > Apps > Google Workspace > Gmail > Authenticate email
Configure DMARC with monitoring: v=DMARC1; p=none; rua=mailto:dmarc@company.com
Progress DMARC to enforcement per organizational readiness

Tools & Resources

Google Admin Console: Central management for all security settings
Google Workspace Security Investigation Tool: Threat analysis and response
Google Security Center: Security health recommendations and dashboard
Gmail Security Sandbox: Attachment detonation for enterprise licenses
Google Advanced Protection Program: Strongest account security

Validation

Spoofing protection blocks test email with lookalike domain
Pre-delivery scanning catches test phishing with delayed weaponization
Attachment protection warns on test encrypted attachment
Enhanced Safe Browsing blocks known phishing URL clicked in email
APP-enrolled accounts reject non-FIDO2 authentication attempts
SPF, DKIM, DMARC all pass for outbound messages
