# Implementing Wireless Security Policy

## Overview

Wireless security policy provides the governance framework for secure wireless operations.
This technique covers policy development aligned with regulatory requirements, BYOD
controls, network access control (NAC) with 802.1X, device compliance enforcement,
wireless audit procedures, and policy exception management. Effective policy bridges
technical controls with organizational requirements.

Mode: `[MODE: ARCHITECT]` for this technique.

## Prerequisites

| Requirement | Details |
|---|---|
| Organizational security policy framework | Required |
| Wireless network inventory and architecture documentation | Required |
| NAC solution (FreeRADIUS, ISE, PacketFence, or similar) | Required |
| Compliance requirements mapping (PCI DSS, HIPAA, SOC 2) | Required |
| Stakeholder approval process for policy publication | Required |

## Key Concepts

### Wireless Security Policy Framework

```
Wireless Security Policy Architecture:
├── Governance
│   ├── Policy scope and applicability
│   ├── Roles and responsibilities
│   ├── Exception and waiver process
│   └── Review and update cadence
├── Access Control
│   ├── 802.1X authentication requirements
│   ├── Certificate-based device authentication
│   ├── BYOD enrollment and compliance
│   └── Guest access procedures
├── Network Standards
│   ├── Encryption requirements (WPA3 minimum)
│   ├── SSID naming conventions
│   ├── VLAN segmentation requirements
│   └── Rogue AP prohibition and detection
├── Device Management
│   ├── Authorized AP inventory
│   ├── Firmware update requirements
│   ├── Configuration change control
│   └── End-of-life decommissioning
└── Audit & Compliance
    ├── Wireless security assessment schedule
    ├── Penetration testing requirements
    ├── Compliance reporting
    └── Incident response integration
```

### 802.1X NAC Configuration

```bash
# FreeRADIUS configuration for wireless 802.1X
cat > /etc/freeradius/3.0/sites-available/wireless << EOF
server wireless {
    listen {
        type = auth
        ipaddr = *
        port = 1812
    }
    listen {
        type = acct
        ipaddr = *
        port = 1813
    }
    authorize {
        filter_username
        preprocess
        eap {
            ok = return
        }
        files
        ldap
        expiration
        logintime
    }
    authenticate {
        eap
    }
    post-auth {
        update reply {
            Tunnel-Type := VLAN
            Tunnel-Medium-Type := IEEE-802
        }
        if (&control:Auth-Type == "EAP-TLS") {
            update reply {
                Tunnel-Private-Group-Id := "10"
            }
        }
        elsif (&User-Name =~ /^guest/) {
            update reply {
                Tunnel-Private-Group-Id := "100"
            }
        }
        Post-Auth-Type REJECT {
            attr_filter.access_reject
        }
    }
}
EOF

# Enable the wireless site
ln -sf /etc/freeradius/3.0/sites-available/wireless \
       /etc/freeradius/3.0/sites-enabled/wireless

# Test RADIUS authentication
radtest user password localhost 0 testing123
eapol_test -c eapol_test.conf -s testing123
```

### Device Compliance Enforcement

```bash
# NAC posture assessment script for endpoint compliance
python3 -c "
import json, subprocess, sys

def check_compliance():
    checks = {}

    # Check OS patch level
    kernel = subprocess.run(['uname', '-r'], capture_output=True, text=True).stdout.strip()
    checks['kernel_version'] = kernel

    # Check firewall status
    fw = subprocess.run(['ufw', 'status'], capture_output=True, text=True)
    checks['firewall_active'] = 'active' in fw.stdout.lower()

    # Check disk encryption
    luks = subprocess.run(['lsblk', '-o', 'NAME,TYPE,FSTYPE'], capture_output=True, text=True)
    checks['disk_encrypted'] = 'crypto_LUKS' in luks.stdout

    # Check antivirus (ClamAV example)
    av = subprocess.run(['freshclam', '--version'], capture_output=True, text=True)
    checks['av_current'] = av.returncode == 0

    compliant = all([checks['firewall_active'], checks['disk_encrypted']])
    result = {'compliant': compliant, 'checks': checks}
    print(json.dumps(result, indent=2))
    return 0 if compliant else 1

sys.exit(check_compliance())
"
```

### Wireless Audit Procedure

```bash
# Automated wireless security audit script
AUDIT_DIR="/var/log/wireless-audit/$(date +%Y%m%d)"
mkdir -p "$AUDIT_DIR"

# 1. Enumerate all wireless networks
sudo airodump-ng --band abg wlan0mon -w "$AUDIT_DIR/scan" \
  --output-format csv 2>/dev/null &
sleep 120 && kill %1

# 2. Check for unauthorized APs
comm -13 \
  <(sort /etc/wids/authorized_aps.txt) \
  <(awk -F',' '/^[0-9A-F]/{print $1}' "$AUDIT_DIR/scan-01.csv" | sort) \
  > "$AUDIT_DIR/unauthorized_aps.txt"

# 3. Verify encryption standards
awk -F',' '/^[0-9A-F]/{
  if($6 !~ /WPA3/ && $6 !~ /WPA2/) print $1,$6,$14
}' "$AUDIT_DIR/scan-01.csv" > "$AUDIT_DIR/weak_encryption.txt"

# 4. Generate audit report
echo "=== Wireless Security Audit Report ===" > "$AUDIT_DIR/report.txt"
echo "Date: $(date)" >> "$AUDIT_DIR/report.txt"
echo "Unauthorized APs: $(wc -l < $AUDIT_DIR/unauthorized_aps.txt)" >> "$AUDIT_DIR/report.txt"
echo "Weak Encryption: $(wc -l < $AUDIT_DIR/weak_encryption.txt)" >> "$AUDIT_DIR/report.txt"
```

## Workflow

### Step 1: Policy Development

Draft wireless security policy covering access control, encryption, and BYOD.

```bash
# Review current wireless posture
sudo airodump-ng --band abg wlan0mon -w policy_audit
```

### Step 2: NAC Deployment

Configure 802.1X authentication with RADIUS for all corporate SSIDs.

### Step 3: BYOD Controls

Implement device enrollment, compliance checks, and network segmentation.

### Step 4: Audit Schedule

Establish quarterly wireless security assessment and annual penetration testing.

### Step 5: Policy Publication

Obtain stakeholder approval and publish policy with training requirements.
