Example: OWASP ZAP
OWASP ZAP (Zed Attack Proxy) is a free, open-source web application security scanner. It can be used to perform automated vulnerability scans of web applications, identifying common security flaws such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). Users can schedule ZAP to run scans on a regular basis, providing continuous monitoring for web application vulnerabilities.
Performance Monitoring Scans
Performance monitoring scans are designed to continuously assess the performance of systems and applications, ensuring optimal resource utilization, identifying bottlenecks, and preventing performance degradation. These scans provide valuable insights into system behavior, enabling proactive optimization and troubleshooting.
Metrics to Monitor
- CPU Utilization: Tracks the percentage of CPU resources being used by processes and applications.
- Memory Usage: Monitors the amount of RAM being used by the system.
- Disk I/O: Measures the rate at which data is being read from and written to disk.
- Network Latency: Measures the time it takes for data to travel between systems.
- Application Response Time: Tracks the time it takes for applications to respond to user requests.
Tools for Performance Monitoring
- Nagios: An open-source monitoring tool that can monitor system resources, network services, and applications.
- Prometheus: An open-source monitoring and alerting toolkit designed for cloud-native environments.
- Datadog: A cloud-based monitoring platform that provides real-time visibility into system performance.
- New Relic: An application performance monitoring (APM) tool that provides detailed insights into application performance.
Example: Setting up a CPU utilization alert in Prometheus
`groups:
– name: CPU Utilization
rules:
– alert: HighCPUUtilization
expr: 100 – (avg by (instance) (irate(node_cpu_seconds_total{mode=”idle”}[5m])) * 100) > 80
for: 5m
labels:
severity: critical
annotations:
summary: “High CPU utilization detected on {{ $labels.instance }}”
description: “CPU utilization is above 80% on {{ $labels.instance }} for more than 5 minutes.”`
This setup ensures you are immediately alerted when CPU usage exceeds the defined threshold, allowing for prompt investigation and remediation.
