Hostscan ensures network security by verifying that devices comply with security policies before connecting. It checks antivirus, firewall, and updates to enhance cybersecurity and maintain network integrity.
Introduction
In today’s digital age, maintaining cybersecurity is crucial. One of the essential tools in a network administrator’s arsenal is Hostscan, a robust feature designed to ensure that endpoints comply with security policies before they connect to a network.
If you’ve ever seen the message “Hostscan is performing software scan,” you might wonder what it means and why it’s important. This article will delve into the details, explaining the functionality, importance, and best practices associated with Hostscan.
What is Hostscan?
Hostscan is a module used in conjunction with Cisco’s AnyConnect Secure Mobility Client. It performs endpoint posture assessments, ensuring that devices attempting to connect to a network meet specific security criteria.
By running a series of checks, Hostscan verifies the presence and status of security applications such as antivirus software, firewall settings, and operating system updates.
Why is Hostscan Important?
Enhanced Security:
Hostscan ensures that all endpoints comply with the organization’s security policies, reducing the risk of malware and other cyber threats.
Compliance:
For many industries, adhering to regulatory standards is mandatory. Hostscan helps organizations meet these compliance requirements by enforcing security policies.
Network Integrity:
By preventing non-compliant devices from connecting, Hostscan helps maintain the overall integrity and performance of the network.

How Does Hostscan Work?
Initiation:
When a device attempts to connect to a network via the Cisco AnyConnect client, Hostscan is automatically triggered.
Assessment:
Hostscan performs a thorough scan of the device, checking for compliance with the predefined security policies. This includes verifying antivirus updates, firewall settings, and ensuring that the operating system is up-to-date.
Validation:
If the device meets all the security requirements, it is granted access to the network. If not, it is either denied access or granted limited access, depending on the organization’s policies.
Key Features of Hostscan:
Antivirus Compliance Check:
Hostscan verifies the presence and status of antivirus software, ensuring that it is active and up-to-date.
Firewall Status Check:
It checks if the firewall is enabled and properly configured, which is essential for protecting against unauthorized access.
Operating System Updates:
Hostscan ensures that the operating system is updated with the latest security patches, reducing vulnerabilities.
Custom Checks:
Administrators can configure Hostscan to perform custom checks based on specific organizational requirements.
Benefits of Using Hostscan:
Proactive Security:
By identifying and mitigating potential threats before they enter the network, Hostscan provides a proactive approach to cybersecurity.
Improved Compliance:
Hostscan helps organizations adhere to industry standards and regulations, such as GDPR, HIPAA, and PCI-DSS.
Enhanced User Experience:
By ensuring that only compliant devices connect to the network, Hostscan helps maintain network performance and reliability.
Scalability:
Hostscan can be scaled to accommodate growing networks, making it suitable for organizations of all sizes.

Common Issues and Troubleshooting:
Slow Performance:
Sometimes, users may experience slow performance during the scan. Ensuring that the endpoint’s hardware and software are optimized can help alleviate this issue. Regularly clearing cache and temporary files can also improve performance.
Scan Failures:
If the scan fails, check the device’s security software and settings. Ensure that all required updates are installed and that security applications are running correctly. Restarting the device can often resolve scan failures.
Access Denied:
If access is denied, review the security policies set by the organization and ensure that the endpoint complies with them. Sometimes, adjusting the security settings or updating the device can resolve access issues.
Best Practices for Using Hostscan:
Regular Updates:
Keep your security software and operating system up-to-date to ensure compliance and improve scan performance. Enable automatic updates to simplify this process.
Policy Review:
Regularly review and update your security policies to address new threats and compliance requirements. Conduct periodic audits to ensure policies are effective.
User Training:
Educate users about the importance of compliance and how to maintain their devices to avoid connection issues. Provide training sessions and resources to help users understand best practices.
Testing and Validation:
Before deploying Hostscan widely, test it on a subset of devices to identify and resolve any issues. Regularly validate that Hostscan is working as intended and make adjustments as needed.
Advanced Configuration Options:
Custom Endpoint Checks:
Administrators can create custom scripts to perform additional checks on endpoints, tailoring Hostscan to the organization’s specific needs.
Integration with Other Tools:
Hostscan can be integrated with other security tools and systems, such as SIEM (Security Information and Event Management) solutions, for enhanced visibility and response.
Granular Access Controls:
Hostscan allows for granular control over network access, enabling different levels of access based on the compliance status of the device.
