Security Hardening

Implement Advanced Security Measures and Best Practices

Security Assessment Framework

Step 1: Comprehensive Security Audit

`
SLOS → Advanced → Security → Security Audit
`

Security Audit Report:
`json
{
“audit_timestamp”: “2024-12-31T11:00:00Z”,
“auditscope”: “fullsystem”,
“security_score”: 85,
“critical_findings”: 0,

“pcidss”: “notapplicable”
},
“risk_assessment”: {
“overall_risk”: “medium”,
“databreachprobability”: “low”,
“impact_severity”: “high”
}
}
`

Step 2: Vulnerability Scanning

`
SLOS → Advanced → Security → Vulnerability Scan
`

Vulnerability Scan Results:
`json
{
“scan_engine”: “multiple”,
“scanners_used”: [“WPScan”, “Nikto”, “OpenVAS”],
“vulnerabilities_found”: [
{
“id”: “WP-VULN-001”,

}
],
“false_positives”: 3,
“scan_coverage”: “98%”
}
`

Step 3: Penetration Testing Setup

`
SLOS → Advanced → Security → Penetration Testing
`

Penetration Testing Configuration:
`json
{
“testingmethodology”: “owasptop_10″,
“test_types”: [
“network_scanning”,
“webapplicationtesting”,
“api_testing”,
“databasesecuritytesting”
],

“consentmanagementapi”,
“admin_dashboard”,
“userdataportal”
],
“outofscope”: [
“thirdpartyservices”,
“external_integrations”
]
}
}
`

Advanced Access Control

Step 1: Implement Role-Based Access Control (RBAC)

`
SLOS → Advanced → Security → Access Control
`

RBAC Configuration:
`json
{
“roles_defined”: [
{
“rolename”: “complianceofficer”,
“permissions”: [
“readconsentdata”,
“managecookiesettings”,
“viewauditlogs”,
“generate_reports”
],
“restrictions”: [
“nodatadeletion”,
“nosystemconfiguration”
]
},
{
“rolename”: “dataprotection_officer”,
“permissions”: [
“fullconsentdata_access”,
“managedsrrequests”,
“configureprivacysettings”,
“viewallaudit_logs”
],
“restrictions”: []
},
{
“rolename”: “itadministrator”,
“permissions”: [
“system_configuration”,
“user_management”,
“security_settings”,
“backup_management”
],
“restrictions”: [
“noconsentdata_modification”
]
}
],
“permission_matrix”: {
“consent_data”: {
“read”: [“complianceofficer”, “dataprotection_officer”],
“write”: [“dataprotectionofficer”],
“delete”: [“dataprotectionofficer”]
},
“system_settings”: {
“read”: [“all_roles”],
“write”: [“it_administrator”],
“delete”: [“it_administrator”]
}
}
}
`

Step 2: Multi-Factor Authentication (MFA)

`php
// Advanced MFA implementation
class AdvancedMFA {
private $mfamethods = [‘totp’, ‘sms’, ’email’, ‘hardwaretoken’];

public function setupMFA($user_id, $method = ‘totp’) {

private function setupTOTP($user_id, $secret) {
require_once ‘vendor/phpqrcode/qrlib.php’;

$issuer = get_bloginfo(‘name’);

case ’email’:
return $this->verifyEmail($user_id, $code);
default:
return false;
}
}

private function verifyTOTP($secret, $code) {
$time = floor(time() / 30);
$valid_codes = [];

// Check current and adjacent time windows
for ($i = -1; $i <= 1; $i++) { $valid_codes[] = $this->generateTOTP($secret, $time + $i);

$offset = ord($hash[19]) & 0xf;
$code = (ord($hash[$offset]) & 0x7f) << 24 | (ord($hash[$offset + 1]) & 0xff) << 16 | (ord($hash[$offset + 2]) & 0xff) << 8 | (ord($hash[$offset + 3]) & 0xff); return strpad($code % (10 ** 6), 6, ‘0’, STRPAD_LEFT);
}
}
`

Step 3: Session Security Management

`php
// Advanced session security
class SessionSecurityManager {
private $session_config = [
‘lifetime’ => 3600, // 1 hour
‘idle_timeout’ => 1800, // 30 minutes
‘maxsessionsper_user’ => 3,

// Session hijacking detected
$this->destroySession();
$this->logSecurityEvent(‘sessionhijackingattempt’, [
‘userid’ => $userid,
‘ipaddress’ => $SERVER[‘REMOTE_ADDR’],
‘useragent’ => $SERVER[‘HTTPUSERAGENT’]

wp_die(‘Session security violation detected.’);
}

$SESSION[‘fingerprint’] = $currentfingerprint;

// Check idle timeout
$lastactivity = $SESSION[‘last_activity’] ?? time();
if (time() – $lastactivity > $this->sessionconfig[‘idle_timeout’]) {

exit;
}

$SESSION[‘lastactivity’] = time();
}

private function generateSessionFingerprint() {
return hash(‘sha256’, $SERVER[‘REMOTEADDR’] . $SERVER[‘HTTPUSER_AGENT’]);
}

private function manageConcurrentSessions() {
$userid = getcurrentuserid();
if (!$user_id) return;

global $wpdb;

// Clean expired sessions
$wpdb->query($wpdb->prepare(
“DELETE FROM wpslosuser_sessions
WHERE userid = %d AND lastactivity < %d", $user_id, time() - $this->session_config[‘lifetime’]

‘createdat’ => currenttime(‘mysql’)
]);
}
}
`

Data Encryption at Rest

Step 1: Implement Database Encryption

`
SLOS → Advanced → Security → Data Encryption
`

Database Encryption Configuration:
`json
{
“encryptionmethod”: “aes256gcm”,
“keymanagement”: “awskms”,
“encrypted_tables”: [
“wpslosconsent_log”,
“wpslosuser_data”,
“wpslosaudit_log”
],
“encrypted_columns”: [
“personal_data”,
“ip_address”,
“user_agent”,
“consent_details”
],
“encryption_performance”: {
“encryption_overhead”: “5%”,
“decryption_overhead”: “3%”,
“keyrotationtime”: “2_hours”
}
}
`

Step 2: Transparent Data Encryption (TDE)

`sql
— Enable TDE for MySQL
INSTALL PLUGIN keyringfile SONAME ‘keyringfile.so’;

— Configure keyring
SET GLOBAL keyringfiledata = ‘/var/lib/mysql-keyring/keyring’;

— Create encrypted tablespace
CREATE TABLESPACE slosencryptedts
ADD DATAFILE ‘slosencryptedts.ibd’
ENCRYPTION = ‘Y’;

— Alter existing tables to use encrypted tablespace
ALTER TABLE wpslosconsent_log
TABLESPACE slosencryptedts;

ALTER TABLE wpslosuser_data
TABLESPACE slosencryptedts;

— Verify encryption
SELECT
TABLE_SCHEMA,
TABLE_NAME,
CREATE_OPTIONS
FROM information_schema.TABLES
WHERE TABLE_SCHEMA = DATABASE()
AND TABLENAME LIKE ‘wpslos_%’
AND CREATE_OPTIONS LIKE ‘%ENCRYPTION%’;
`

Step 3: Application-Level Encryption

`php

return $keys[$context][‘current_version’] ?? ‘v1’;
}

public function rotateEncryptionKeys() {
$contexts = [‘consentdata’, ‘userdata’, ‘audit_logs’];

foreach ($contexts as $context) {

updateoption(‘sloslastkeyrotation’, time());
}

private function rotateKeyForContext($context) {
$keys = getoption(‘slosencryption_keys’, []);
$newversion = ‘v’ . (intval(substr($keys[$context][‘currentversion’], 1)) + 1);
$new_key = $this->generateKey();

$keys[$context][$newversion] = $newkey;
$keys[$context][‘currentversion’] = $newversion;

// Keep only last 3 versions
$versions = array_keys($keys[$context]);
if (count($versions) > 4) { // current_version + 3 old versions
sort($versions);
$toremove = arrayslice($versions, 0, -4);

private function scheduleDataReencryption($context, $new_version) {
// Schedule background job to re-encrypt data
wpschedulesingleevent(time() + 60, ‘slosreencrypt_data’, [
‘context’ => $context,
‘newversion’ => $newversion
]);
