Network Monitoring and Vulnerability Assessment

---

Network Monitoring Tools:

SolarWinds Network Performance Monitor:

• Functionality: Provides comprehensive network performance monitoring with fault, performance, and availability tracking.

• Key Features: Customizable dashboards, NetPath for critical path visualization, intelligent alerts.

# Initialize SolarWinds NPM API client
npm_client = SolarWindsNPMClient('api_key', 'server_url')

# Retrieve network performance data
network_performance_data = npm_client.get_network_performance()

# Analyze data for any performance issues
for node in network_performance_data.nodes:
    if node.status == 'down':
        alert('Node down: ' + node.name)

Nagios:

• Functionality: Offers complete monitoring of applications, services, operating systems, network protocols, system metrics, and network infrastructure.

• Key Features: Alerting system, comprehensive reporting, extendable architecture through plugins.

# Initialize Nagios client
nagios_client = NagiosClient('username', 'password', 'server_url')

# Check the status of services
services_status = nagios_client.get_services_status()

# Alert if any service is critical
for service in services_status:
    if service.status == 'CRITICAL':
        alert('Critical service: ' + service.name)

Wireshark:

• Functionality: A network protocol analyzer used for troubleshooting, analysis, and development.

• Key Features: Deep inspection of hundreds of protocols, live capture, offline analysis, and VoIP analysis.

# Read pcap file
packets = read_pcap('network_traffic.pcap')

# Analyze packets
for packet in packets:
    if packet_contains_suspicious_pattern(packet):
        alert('Suspicious packet detected')

PRTG Network Monitor:

• Functionality: An all-inclusive monitoring solution that ensures the availability of network components while also measuring traffic and usage.

• Key Features: Multiple sensors for various services, customizable interface, in-depth reporting.

# Initialize PRTG API client
prtg_client = PRTGClient('api_token', 'server_url')

# Retrieve sensor data
sensors_data = prtg_client.get_sensors()

# Check for down sensors
for sensor in sensors_data:
    if sensor.status == 'down':
        alert('Sensor down: ' + sensor.name)

Vulnerability Assessment Tools:

Qualys:

• Functionality: Provides cloud-based vulnerability management, detecting vulnerabilities and ensuring compliance.

• Key Features: Continuous monitoring, web application scanning, threat protection.

# Initialize Qualys API client
qualys_client = QualysAPIClient('username', 'password')

# Run vulnerability scan
scan_id = qualys_client.start_vulnerability_scan('scan_target')

# Check scan results
scan_results = qualys_client.get_scan_results(scan_id)
for vulnerability in scan_results.vulnerabilities:
    if vulnerability.severity >= HIGH_SEVERITY_THRESHOLD:
        alert('High severity vulnerability found: ' + vulnerability.name)

Rapid7 InsightVM:

• Functionality: A risk-centric vulnerability management tool that provides clarity into risk and across the entire IT ecosystem.

• Key Features: Real-time analytics, live dashboards, automated actions for remediation.

# Initialize InsightVM API client
insightvm_client = InsightVMClient('api_key', 'server_url')

# Retrieve latest scan results
latest_scan = insightvm_client.get_latest_scan()

# Analyze for high-risk vulnerabilities
for vulnerability in latest_scan.vulnerabilities:
    if vulnerability.risk_score > RISK_SCORE_THRESHOLD:
        alert('High-risk vulnerability detected: ' + vulnerability.title)

Tenable Nessus:

• Functionality: A widely deployed vulnerability scanner used to identify vulnerabilities, configuration issues, and malware.

• Key Features: High-speed asset discovery, vulnerability assessment, configuration and compliance checks.

# Initialize Nessus API client
nessus_client = NessusClient('api_key', 'server_url')

# Perform a scan
scan_id = nessus_client.create_scan('scan_name', 'scan_policy', 'target')
nessus_client.start_scan(scan_id)

# Retrieve scan results
scan_results = nessus_client.get_scan_results(scan_id)
for finding in scan_results.findings:
    if finding.severity == 'High':
        alert('High severity finding: ' + finding.name)

OpenVAS:

• Functionality: An open-source vulnerability scanner and manager that can detect numerous security vulnerabilities.

• Key Features: Comprehensive and up-to-date vulnerability testing, multiple scanning targets.

# Initialize OpenVAS client
openvas_client = OpenVASClient('username', 'password', 'server_url')

# Start a new vulnerability scan
scan_id = openvas_client.start_scan('target_ip')

# Monitor scan progress and retrieve results
scan_results = openvas_client.get_scan_results(scan_id)
for vulnerability in scan_results.vulnerabilities:
    if vulnerability.severity == 'High':
        alert('High severity vulnerability: ' + vulnerability.name)
