OpenVAS is a powerful tool for network security scanning. It uses a system of specialized parts to find weaknesses in your network. IT pros need to know how it works for effective security checks.

This platform uses a client-server model. It separates scanning from user actions. This setup helps big companies do detailed checks without slowing down.

The OpenVAS system has a multi-tier design. It separates tasks into execution, management, and user interaction. This design lets it work well on any network size.

It uses the OpenVAS Management Protocol (OMP) for communication. Users connect through web or command-line interfaces. This makes it easy to manage the system.

The web interface runs on HTTPS port 9392, or sometimes port 443. This lets companies fit it into their security plans. It supports both manual and automated scans.

OpenVAS has several parts that work together. Each part has its own job. Knowing these parts helps admins set up and keep the system running well.

The OpenVAS Scanner is the main engine. It checks systems for vulnerabilities using Network Vulnerability Tests (NVTs). These tests are written in NASL, a scripting language from Nessus.

The OpenVAS Manager is the central part. It sets up scans, schedules them, and handles results. It connects the scanner to user interfaces.

User interaction happens through two main interfaces:

• Greenbone Security Assistant (GSA) – A web interface for easy access to all functions
• OpenVAS CLI – A command-line interface for scripting and automation
• Greenbone Security Feed (GSF) – Updates NVTs and security intelligence

Behind these interfaces are important backend parts. The OpenVAS Libraries handle network communication and data storage. They keep the system running smoothly.

The system uses Redis for temporary data and a database for long-term storage. This setup improves both performance and data keeping.

OpenVAS has a clear method for vulnerability checks. It starts by classifying resources. This step lists what needs to be checked.

Then, it does enumeration to get detailed info about systems. This info decides which tests to run.

The scanner then runs tests to find threats. It checks for known vulnerabilities and weaknesses. This makes sure your network is secure.

After, OpenVAS sorts vulnerabilities by how serious they are. It gives detailed reports to help fix the most important issues first.

Each scan gives detailed results. These include what’s wrong, how bad it is, and how to fix it. It’s important to check these reports often to stay safe.

Installing OpenVAS is the first step in creating a strong vulnerability assessment system for your company. The setup process needs careful planning and attention to details. This ensures your scanner works well and reliably.

Getting your scanning solution set up right from the start helps avoid common problems. It also sets up a stable base for ongoing security checks. We help guide you through each step to get the best results.

Before starting your scanner deployment, make sure your system meets the necessary requirements. This ensures a smooth installation and operation. We suggest checking these requirements carefully to avoid any performance issues.

Your system needs a Linux-based operating system as the base. Supported distributions include Ubuntu, Debian, Fedora, CentOS, RHEL, and Kali Linux. Each has its own benefits based on your environment and infrastructure.

Hardware specs affect scanning performance and capacity:

• Processor: A multi-core CPU is recommended for efficient scanning
• Memory: At least 4GB RAM is needed, but 8GB or more is better for large environments
• Disk Space: You’ll need a lot of storage for NVT databases, scan results, and logs
• Network: Good connectivity is essential for accessing systems and downloading updates

These specs can be adjusted based on your scanning needs and network size. Larger networks may need more resources for smooth assessments.

The OpenVAS installation method varies by Linux distribution. We recommend using package managers for easier setup and maintenance.

For Kali Linux environments, the process is straightforward. Start by updating package lists and upgrading packages. Then, install OpenVAS and run the setup script.

1. Run apt-get update to refresh package lists
2. Execute apt-get dist-upgrade to upgrade system packages
3. Install OpenVAS using apt-get install openvas
4. Launch openvas-setup to automate initial configuration

The openvas-setup script does many important tasks automatically. It creates certificates, updates NVT feeds, and sets up an admin user.

Fedora, RHEL, and CentOS users have a different process. First, set up the Atomicorp repository. Then, install OpenVAS and run the setup script.

Ubuntu environments use PPA repositories for installation. This method provides packages optimized for Ubuntu.

For the latest features, consider source compilation. This method requires technical expertise but offers cutting-edge capabilities.

After installing OpenVAS, proper configuration is key. We guide you through essential steps to set up a ready-to-use environment.

Start by verifying service status across all OpenVAS components. Make sure services are listening on their designated ports.

Next, focus on SSL certificate configuration to secure communication. Use default certificates for testing, but production environments need properly signed certificates.

Administrative credentials need immediate attention. Change the initial password to meet your security policies. Store these credentials securely using your organization’s password management system.

Perform an initial NVT feed update to ensure your scanner has the latest vulnerability definitions. This process downloads thousands of tests and may take time based on your connection speed.

Firewall configuration is essential for network communication while maintaining security. Allow incoming connections to the web interface port and ensure the scanner can reach target systems.

Document your specific configuration parameters and file locations for future reference. Key directories include log files, configuration files, and the primary scanner config.

This documentation is crucial for troubleshooting and system maintenance. Store it in your organization’s configuration management database alongside other critical infrastructure details.

OpenVAS shines when you start running vulnerability scans. These scans check your network for security weaknesses. Learning how to run scans and understand the results helps your team stay ahead of threats.

Scanning is key to keeping your systems safe. Each scan finds new vulnerabilities that could harm your systems.

Setting up scan targets is the first step. You can do this through the Greenbone Security Assistant (GSA) web interface at https://server-ip/. This lets you choose which systems to check.

The web interface makes it easy to pick targets. You can use IP addresses, hostnames, or network ranges. This works for small or big assessments.

For those who like automation or command-line control, the OMP offers full access. The steps are clear and structured:

• Create Target – Use XML commands to specify the target name and host addresses
• Create Task – Associate your target ID with a specific configuration ID
• Start Task – Initiate the scan using the generated task ID
• Retrieve Report – Extract results using the report ID and desired format ID

Save connection details in a file for easier access. This makes running scans faster and supports automated workflows.

The omp command gives detailed control with XML options. It’s great for custom security frameworks.

Scan settings let you adjust how deep you want to scan. This depends on your business needs and network setup.

Scan profiles help you start with the right settings. Quick discovery scans find active hosts fast. Comprehensive assessments check everything but take longer.

Advanced settings let you fine-tune your scans:

1. Port Range Specifications – Choose which ports to scan
2. Timing Parameters – Control scan speed to avoid network issues
3. Authentication Credentials – Use login info for deeper scans
4. Scheduling Capabilities – Run scans at set times

Credentialed scanning is key. It lets OpenVAS see more by logging in. This reduces false negatives and gives better info for fixing issues.

Regular scans keep your security up to date. Match scan times with when you update systems. This way, you can track changes and threats over time.

Understanding scan results is crucial. The reporting interface shows findings in ways that help everyone in your team.

OpenVAS uses a standard system to rate vulnerabilities. Each issue gets a score from 0 to 10, showing how serious it is.

The Common Vulnerability Scoring System (CVSS) gives a clear score for each issue. This helps you decide which problems to fix first.

Each finding comes with a detailed report. This report explains the problem, how it can be exploited, and how to fix it. This helps your team understand what needs to be done.

The reporting interface offers three main views. Summary dashboards give an overview. Detailed vulnerability listings provide the technical details. Trend analysis shows how your security is improving over time.

It’s important to check if the scan results are real. Not every issue is a problem in your specific situation. You need to verify and document false positives to improve future scans.

Getting the most from your penetration testing platform means having clear processes for scan results. This includes validating vulnerabilities, tracking fixes, and updating scan settings as needed.

When picking a security scanner, many factors come into play. You need to compare different tools to find the best fit for your organization. Each tool has its own strengths and weaknesses that affect how well it works.

OpenVAS and commercial scanners like Nessus aim to do the same thing. But they differ in cost, support, and how customizable they are. Knowing these differences helps you choose the right tool for your needs.

OpenVAS started from the Nessus codebase before Nessus became commercial in 2005. Today, OpenVAS still uses NASL (Nessus Attack Scripting Language) for its tests. This shared base helps both platforms detect vulnerabilities well.

But, OpenVAS and Nessus have grown apart. Nessus, now by Tenable, has better user interfaces and easier setup. It also offers compliance reports and professional support.

Nessus costs a lot, with prices for big environments in the tens of thousands annually. Small groups might pay thousands for basic access.

OpenVAS, being free, doesn’t charge for use. It has a huge database of tens of thousands of updated NVTs. You can use it without paying per asset or subscription.

Both OpenVAS and commercial scanners are good at finding vulnerabilities. OpenVAS lets you see how it works, which is great for detailed audits. Commercial scanners have nicer reports but don’t show their inner workings.

OpenVAS has many benefits for many organizations:

• Zero licensing costs: You can scan without paying per asset or subscription, saving money
• Complete transparency: You can check how it works and customize it with the source code
• Unlimited scalability: You can scan as many assets as you want without extra costs
• Community-driven development: It gets updates fast because of community help
• Customization capabilities: You can change how it scans and add your own tests
• No vendor lock-in: You can change or modify it without being stuck with a vendor

But, there are downsides to consider:

• Steeper learning curve: It takes more tech know-how to set up than commercial tools
• Less polished interfaces: It’s not as user-friendly as commercial tools
• Community support dependency: You rely on forums for help, not guaranteed vendor support
• Greater administrative overhead: You need to manage updates and settings yourself
• Limited integrated compliance reporting: You might need to customize reports for certain rules

Choosing between OpenVAS and commercial scanners depends on your needs. If you’re okay with more tech work for cost savings, OpenVAS is good. But if you want easy setup and support, commercial might be better.

OpenVAS is great for certain situations. Knowing when to use it helps fit it into your security plan.

Large asset inventories are a perfect match. Big groups with many devices save money with OpenVAS. It scans all you need without extra costs.

Managed security service providers also benefit. They can offer services without worrying about per-asset fees. This helps them keep costs down and profits up.

Educational and research groups with tight budgets find OpenVAS useful. It offers top-notch security tools without the high cost. Students and researchers get real-world experience.

Organizations needing customization find OpenVAS ideal. You can make it do what you need with the source code. Commercial scanners often limit these changes.

Groups wanting to see how things work choose OpenVAS. It’s open and lets you check its methods. This is key for groups needing to follow strict rules.

But, some situations are better for commercial scanners:

1. Limited internal expertise: If you don’t have security experts, commercial tools might be easier
2. Strict compliance requirements: Some rules need specific reports that commercial tools provide
3. Vendor support requirements: If you need guaranteed help, commercial is safer
4. Rapid deployment needs: Commercial tools are quicker to set up for fast projects

Try both OpenVAS and commercial scanners in test environments. See which fits your needs better. Look at setup, scanning, reporting, and how easy it is to manage.

Your choice depends on your team’s skills, budget, needs, and support preferences. OpenVAS is a strong option for those willing to invest in tech expertise for cost savings and flexibility.

Keeping your OpenVAS up to date is crucial. The latest vulnerability definitions are key to its effectiveness. Without updates, your system misses new security threats.

The world of cybersecurity changes fast. New vulnerabilities are found every day. Not updating your system leaves it open to attacks.

In 2023, over 28,000 new vulnerabilities were discovered. Each one is a new risk for attackers. Your system can only find threats it knows about.

OpenVAS uses the Greenbone Security Feed (GSF) for updates. These updates help your system find new security risks.

But, updates don’t work right away. You need to follow steps to use them. Without the latest updates, your system can’t find new threats.

The main way to update OpenVAS is with the openvas-nvt-sync command. It gets the latest NVT definitions from Greenbone’s servers.

But, just getting updates isn’t enough. The OpenVAS Manager needs to rebuild its NVT cache. This makes the updates active.

We suggest a special update process. It makes sure everything works smoothly and quickly:

1. Find the process IDs for openvassd and openvasmd.
2. Stop these processes gently with the kill command.
3. Use openvasmd –rebuild to update the NVT cache fully.
4. Start both services again.
5. Check if everything is working right with logs or the web interface.

The –rebuild option is faster than –update. It makes sure your NVT database is fully updated.

Set up regular update times based on your security needs. For production systems, we suggest daily NVT updates. This is because new, critical vulnerabilities need quick detection.

Good organizations manage updates carefully. They test new NVTs in non-production areas before using them in real systems.

Good NVT database care includes a few steps. First, track which NVT versions find specific issues. This is important for audits and reviews.

Second, keep records of any custom tests you make. These need their own version control and testing. This ensures they work right after updates.

Third, have a plan for when updates cause problems. While rare, new NVTs can sometimes cause false positives or issues with scanning targets.

Always watch for update problems. Issues like network problems or disk space can stop updates. Set up alerts for these problems.

Make sure your GSF subscription is active. Choose a team for updates and have a backup plan when needed.

Technical problems often pop up during OpenVAS deployments, even with good planning. Even experienced users face challenges that need careful diagnosis. Good troubleshooting skills are key to solving these problems quickly.

OpenVAS’s complex architecture can lead to issues at various points. Knowing where to look and what tools to use can save a lot of time. We’ve gathered common problems and their solutions to help keep your security monitoring smooth.

Installation issues often come from dependency conflicts in environments with many security tools. If your installation fails, start by checking the installation logs. These logs show if all necessary packages are installed and if any are missing.

Storage space can also be a problem during OpenVAS troubleshooting. The databases and scan results take up a lot of space. Make sure your system has enough space before starting the installation, focusing on the directories where OpenVAS stores data.

Permission issues can stop the installation from creating the needed directories and files. The user installing OpenVAS needs the right permissions to write to system directories. If you get access denied errors, check that you’re running the installation with the right admin rights.

Certificate-related problems are common after installation. OpenVAS uses certificates to secure communication between its parts. These certificates expire after a year, causing service failures.

The usual symptom is a 503 service temporary unavailable error. Look at the log files in /var/log/openvas/, like openvasmd.log, for warnings about untrusted or expired certificates. These messages confirm the problem.

To fix certificate issues, you need to create new certificates:

• Use openvas-mkcert -f to make new server certificates
• Run openvas-mkcert-client -n -i to create client certificates
• Restart all OpenVAS services to use the new certificates
• Check if the service works again by accessing the web interface

Where you find the configuration files depends on how you installed OpenVAS. You’ll usually find openvassd.conf in /etc/openvas/ or /usr/local/etc/openvas/. Make sure you know the right path before making any changes.

Scan errors can show up in different ways. Sometimes, the target systems are unreachable due to network issues or firewall blocks. Always check basic network connectivity with ping or traceroute before looking into complex problems.

Authenticated scans fail if the credentials don’t have enough access on the target systems. The scanner needs the right access to gather all the vulnerability information. Check your credentials and make sure they match the needs of your target systems.

Resource exhaustion on the scanner system can cause incomplete scans. This leads to unreliable results. Watch the system resources during scans to see if hardware limits are affecting your scanning solution.

NVT signature verification failures stop specific vulnerability tests from running. If OpenVAS won’t run unsigned NVTs, you’ll see “bad or missing signature. Will not execute this script” errors in the logs. This is a security feature to prevent running compromised or unauthorized tests.

To solve signature verification issues, you need to set up the right GPG key infrastructure:

1. Generate a local GPG key in the OpenVAS GnuPG homedir
2. Import the official OpenVAS Transfer Integrity public key
3. Locally sign the imported key to establish trust
4. Update NVT feeds to apply signatures to all vulnerability tests

Testing individual NVTs helps find out if the problem is with a specific test or a broader system issue. Use the openvas-nasl command for targeted testing. The -p option does parse testing, -t specifies target systems, and -i shows the plugin directory location.

Log files are crucial for finding and fixing problems. The /var/log/openvas/ directory has logs like gsad.log, openvasmd.log, openvassd.dump, and openvassd.messages. Look at these files in chronological order to find when issues started and what changed.

File ownership and permission problems can disrupt OpenVAS even after it’s installed. The scanner and manager need read access to NVT databases, write access to log directories and scan result storage, and execute permissions on plugin directories. Wrong permissions in any area can cause specific failures.

We’ve developed a step-by-step approach to OpenVAS troubleshooting for permission issues. This method helps you find problems fast without trial and error.

Organizations without deep OpenVAS knowledge should keep detailed documentation. Record where logs, configurations, and NVT databases are. Also, document your network setup and firewall rules that affect scanner traffic. Note any custom changes to default settings.

This documentation is very helpful during troubleshooting, whether you’re using community forums or commercial support. Clear records of your setup help support teams understand your situation and offer targeted solutions.

Permission issues often come up after system updates or when security policies change. Always check that the OpenVAS user account has the right access rights. Automated monitoring of service status can help catch problems before they affect your security checks.

When facing persistent scan errors that can’t be fixed with standard troubleshooting, look at network-level factors. Intrusion prevention systems, network address translation, and proxy servers can all interfere with scanning. Comprehensive troubleshooting looks at the whole path from scanner to target, not just the scanner itself.

Organizations that do well with security use a systematic approach to scanning. They focus on making scanning efficient, integrated, and always improving. Using OpenVAS in a disciplined way helps a lot. It makes scanning better, connects it with fixing problems, and keeps systems running smoothly.

Following best practices makes scanning more than just a check. It turns it into a key part of your security plan. By seeing scanning as an ongoing task, you get a better view of your security. This needs careful setup, smooth workflow, and regular upkeep.

Improving scan performance starts with knowing how to set up OpenVAS. The openvassd.conf file has many settings that affect scanning. It’s important to review these settings to find the right balance.

The max_hosts setting controls how many systems are scanned at once, defaulting to 30. If you have strong networks and scanning tools, you can scan more systems at once. But, scanning too many systems can overwhelm your network or trigger alerts. So, it’s good to test and find the best number for your setup.

The max_checks setting, which defaults to 10, controls how many checks are done on each host. Lower values mean less load on systems but longer scans. Higher values make scans faster but might slow down systems that can’t handle it.

The plugins_timeout setting limits how long tests run, defaulting to 320 seconds. This stops tests from running forever and blocking scans. The checks_read_timeout setting controls how long the scanner waits for responses, with a default of 5 seconds for most networks.

It’s very important to enable safe_checks mode in production. This stops tests that could disrupt services or make systems unstable. Test environments can run more aggressive tests without safe_checks to find deeper vulnerabilities.

Scan scheduling should think about network capacity, system importance, and business needs. Scanning during maintenance times can reduce impact on services. Regular scanning of exposed systems keeps them secure.

Grouping scan targets makes results easier to manage and fix. We organize targets by department, importance, or technology. This helps focus on what’s most important and fix problems faster.

Connecting OpenVAS with your security operations makes vulnerability data useful. Integration needs clear processes that link finding vulnerabilities with fixing them across teams and systems.

Automating result export to ticketing systems makes fixing vulnerabilities accountable. Each vulnerability becomes a task for specific teams with clear ownership. This ensures vulnerabilities get fixed through established steps.

Setting up severity-based service level agreements (SLAs) defines how fast vulnerabilities need to be fixed. We suggest the following timeframes:

• Critical vulnerabilities: Fix within 7 days to avoid immediate risks
• High-severity issues: Fix within 30 days to address big security gaps
• Medium-priority findings: Fix within 90 days as resources allow
• Low-severity items: Fix during routine maintenance or upgrades

Regular meetings for vulnerability reviews bring security and infrastructure teams together. These meetings help decide which vulnerabilities to fix first. They consider how important the assets are, how easy it is to exploit them, and any controls that help.

Using dashboards to track vulnerability trends and fixes shows how well your security is doing. These dashboards help show your security program’s success to others and find areas that need more work. Important metrics include how fast vulnerabilities are fixed, how often they come back, and how well your systems are covered.

For maximum automation, the OMP (OpenVAS Management Protocol) command-line interface lets you script entire workflows. This automation can create targets, start scans, get results, and make reports with little human help. Storing connection details in config files keeps scripts secure and automates more.

Remember, scanning is just one part of a complete security program. The best security comes from integrating OpenVAS with patch management, SIEM systems, asset management, and risk management. This way, you can fix problems, track attacks, see your whole infrastructure, and make smart security choices.

Keeping OpenVAS working well needs regular upkeep. We’ve found several key tasks to keep it running smoothly.

Daily or weekly NVT feed updates keep your scanning up to date. New vulnerabilities come out all the time, and old ones leave gaps in your scans. Automated updates keep you current without human mistakes.

Regularly check and adjust your scan settings to match your changing environment. As your systems and infrastructure change, your scans need to too. Quarterly reviews help find ways to improve and remove old targets.

Backing up scan results and settings prevents losing important data. We recommend automated backups with offsite storage to protect against system failures or security breaches.

Watching system resources ensures you have enough power for scanning. As you scan more or have more targets, you might need to upgrade your scanner. Keeping an eye on resources helps catch problems before they slow you down.

Here’s a checklist for keeping OpenVAS reliable:

1. Update vulnerability definitions daily or at least weekly
2. Review scan settings quarterly for better performance
3. Backup scan databases and settings weekly with tested recovery plans
4. Monitor disk space, memory, and CPU all the time
5. Clear out old scan results monthly to keep databases small
6. Test disaster recovery plans every six months to make sure you can recover
7. Do access reviews quarterly to keep permissions up to date

Keeping old scan results helps manage database size while keeping history for analysis. Keeping 12-18 months of history is usually a good balance. Make sure archived results are still accessible for compliance or forensic needs.

Testing disaster recovery plans shows you can recover after problems. Just having plans isn’t enough—testing them shows you’re ready. This helps find gaps in your backup or recovery plans.

Doing access reviews regularly keeps only authorized people using OpenVAS. As staff changes, old accounts or too many permissions can be a risk. Quarterly reviews help keep your system secure.

OpenVAS is not alone in its support system. It has a strong community, resources, and professional help. Using any tool like OpenVAS needs more than just knowing how to use it. You need good guidance, to learn from others, and expert help when needed.

Success comes from using all the tools around your security system. You need to know where to find answers, how to talk to others, and when to ask for help.

The official Greenbone Networks documentation is key to understanding OpenVAS. Start with the basics to avoid mistakes. Knowing how the parts work together is crucial.

• OpenVAS: This is the scanner that does the actual tests
• GVM (Greenbone Vulnerability Management): This is the whole framework
• GSE (Greenbone Source Edition): This is the free version for everyone
• GSM (Greenbone Security Manager): This is the paid version with extra features

Knowing these terms helps you find what you need faster. Use the right words when you search for answers.

Start with installation guides for your Linux. Then, learn how to set up scans and manage targets. Don’t forget to explore advanced topics like OMP protocol specifications and custom NVT development.

The API docs are key for integrating OpenVAS with other systems. They show how to work with all GVM parts programmatically.

Teams with strong Linux and security skills often use community resources. They get commercial support for urgent needs. Teams with less expertise might need professional help to get started.

Think carefully about your team’s skills before choosing support. Consider your team’s availability, Linux knowledge, and experience with security. The best choice balances cost and reliability.

Helping others in the community is important. Share your solutions and help others with similar problems. This way, everyone benefits from your experience.

This sharing spirit is what makes open-source tools valuable. Every contribution, big or small, helps others. It strengthens security across the industry.

The evolution of OpenVAS shows strategic moves to stay strong in today’s security world. It was rebranded to separate GVM (Greenbone Vulnerability Management) from OpenVAS. This change makes the system clearer and more modular.

Teams removed the old daemon mode from the scanner. Now, it works as a command-line app with clean layers. This makes the scanner better at its job and safer.

The new design also supports running in containers and cloud environments better.

Future updates will focus on making things automated and easier to integrate with DevOps pipelines. The API will get better, making it easier to use with other security tools. The NVT database will keep growing to cover new tech like cloud, containers, and IoT.

There’s a big push for better risk assessment, not just using CVSS scores.
