OpenVAS

OpenVAS is a popular Vulnerability scanner used for Network security and Compliance auditing, developed by Greenbone Networks with contributions from MITRE Corporation, SANS Institute, and US Department of Defense. It is widely used by organizations such as NASA, IBM, and Cisco Systems to identify and manage vulnerabilities in their IT infrastructure. OpenVAS is often compared to other vulnerability scanners like Nessus, Qualys, and Retina, and is known for its comprehensive Vulnerability management capabilities, which include Risk assessment and Penetration testing.

Introduction

OpenVAS is an Open-source software solution that provides a comprehensive Vulnerability management platform, including Vulnerability scanning, Configuration auditing, and Compliance scanning. It is designed to identify vulnerabilities in IT systems, including Operating systems, Applications, and Network devices, and provides detailed reports and recommendations for remediation, similar to those provided by Symantec, McAfee, and Trend Micro. OpenVAS is widely used by organizations such as Microsoft, Google, and Amazon Web Services to improve their Cybersecurity posture and comply with regulatory requirements like PCI DSS, HIPAA, and GDPR. The solution is also integrated with other security tools, such as Snort, OSSEC, and Splunk, to provide a comprehensive security monitoring and incident response capability.

History

The OpenVAS project was launched in 2005 by Greenbone Networks, a company founded by Dr. Jan Ole Malchow and Dr. Reinhard Schröder, with the goal of creating a comprehensive Vulnerability management platform. The project was initially based on the Nessus scanner, which was Open-source software at the time, and was developed in collaboration with MITRE Corporation, SANS Institute, and other organizations. Over the years, OpenVAS has evolved to include new features and capabilities, such as Cloud computing support, Containerization support, and Artificial intelligence-based vulnerability analysis, similar to those offered by Palo Alto Networks, Check Point, and Fortinet. Today, OpenVAS is widely used by organizations around the world, including US Department of Defense, NASA, and European Union agencies.

Architecture

The OpenVAS architecture consists of several components, including the OpenVAS Scanner, OpenVAS Manager, and OpenVAS Administrator, which provide a scalable and flexible Vulnerability management platform. The solution uses a Client-server architecture, with the scanner and manager components communicating with each other using XML-based protocols, similar to those used by VMware, Citrix Systems, and Red Hat. The OpenVAS architecture is designed to support large-scale deployments, with features like Load balancing, High availability, and Scalability, making it suitable for use in complex IT environments, such as those found in Banking and finance, Healthcare, and Government sectors.

Features

OpenVAS provides a wide range of features, including Vulnerability scanning, Configuration auditing, and Compliance scanning, which enable organizations to identify and manage vulnerabilities in their IT systems. The solution also includes features like Risk assessment, Penetration testing, and Vulnerability prioritization, which help organizations to prioritize and remediate vulnerabilities based on their severity and impact, similar to those offered by IBM Security, HP Enterprise Security, and Dell SecureWorks. OpenVAS also supports Integration with other security tools, such as SIEM systems, IDS/IPS systems, and Firewall systems, to provide a comprehensive security monitoring and incident response capability, similar to those provided by RSA Security, Symantec, and McAfee.

Vulnerability Scanning

OpenVAS provides comprehensive Vulnerability scanning capabilities, including Network scanning, Port scanning, and Service scanning, which enable organizations to identify vulnerabilities in their IT systems. The solution uses a Signature-based detection approach, which involves comparing the characteristics of potential vulnerabilities against a database of known vulnerabilities, similar to those used by Snort, OSSEC, and Suricata. OpenVAS also supports Anomaly-based detection, which involves identifying unusual patterns of behavior that may indicate a vulnerability or an attack, similar to those offered by IBM QRadar, Splunk, and LogRhythm.

Integration and Compatibility

OpenVAS is designed to be highly integrable and compatible with other security tools and systems, including SIEM systems, IDS/IPS systems, and Firewall systems. The solution supports API-based integration with other security tools, such as Splunk, ELK Stack, and Graylog, and also provides Native integration with other security solutions, such as Snort, OSSEC, and Suricata. OpenVAS is also compatible with a wide range of Operating systems, including Linux, Unix, and Windows, and supports Virtualization and Cloud computing environments, such as those provided by VMware, Amazon Web Services, and Microsoft Azure. The solution is widely used by organizations such as NASA, IBM, and Cisco Systems to improve their Cybersecurity posture and comply with regulatory requirements like PCI DSS, HIPAA, and GDPR.
