This allows for piecemeal scanning rather than a slower, complete scan. While there are many types of security software tools on the market, using vulnerability scanning software is a critical first step toward protecting your network while relieving some of the manual VM burdens. Check out a tool like Network Configuration Manager as an all-in-one solution to save time and better manage your vulnerability detection strategy.
Identifying vulnerabilities — Admins need to be able to identify security holes in their network, across workstations, servers, firewalls, and more. It takes automated software to catch as many of these vulnerabilities as possible. While very small offices that happen to have robust IT resources may be tempted to manage network security manually, businesses of any size will benefit from the time-saving assistance an automated tool provides.
Evaluating risks — Not all vulnerabilities are equally urgent. Scanning tools can classify and categorize vulnerabilities to help admins prioritize the most worrisome issues. The right tool can help you automate the process of provisioning devices. This vulnerability can be prevented with better network segmentation and management of user group privileges.
Unknown devices — Unidentified or unmanaged assets on your network are never good news. Account abuse — Unfortunately, insiders sometimes abuse their privileges, causing purposeful or inadvertent leaks of sensitive information, or the misconfiguration of programs, causing additional security holes. Furthermore, admins might allow default credentials, leave unused users or groups in the system, or assign incorrect privileges, all of which pose a security risk.
Security feature configurations — How you manage your security settings and infrastructure could open risks. To avoid vulnerabilities, watch for firewall or OS misconfigurations. In addition to avoiding these applications, watch out for suspicious downloads, insecure remote desktop sharing software, and software nearing the end of its life.
Missing updates — One major cause of security issues on networks is basic errors in software and firmware configuration or cases where configuration levels become uneven across the network.
Hackers can quickly exploit these gaps. Back to Top Evaluating Risks of Vulnerabilities Vulnerability scanners often produce a long list of risk factors, and admins are rarely able to resolve all identified risks immediately and effectively—it simply requires too many resources to assess and address every single item.
Back to Top Top Vulnerability Management Techniques Vulnerability scanning is a crucial technique for preventing security breaches on your network. Furthermore, it overlaps with other vulnerability management techniques that can provide critical network insights: Penetration testing — Also called pen testing, this practice is essentially about hacking your own system before someone else can.
This can be a highly effective way to identify security gaps, although it is time-intensive and potentially costly, making regular manual testing a viable option only for larger, well-resourced companies.
Breach and attack simulation — This is similar to pen testing but is ongoing, automated, and quantifiable. Essentially, it enables you to ensure your security measures are effective by subjecting them to regular testing and validation. Antivirus monitoring — Antivirus software is popular, but it takes a limited approach to protect your network. These antivirus tools have less to do with managing network security gaps than with addressing specific threats, like ransomware , spyware, Trojans , and the like.
Web application scanning tools look for vulnerabilities within web apps, either by simulating attacks or by analyzing back-end code. They can catch cross-site scripting, SQL injection, path traversal, insecure configurations, and more.
These tools work on a similar principle as vulnerability scanners. Configuration management — Although many admins are concerned with zero-day attacks, evidence to suggests misconfigurations and missing patches are the major weak points for damaging hacks. Many admins leave these kinds of risks open for months or years without recognizing or remediating them, even if fixes are available. Scanning for and fixing these errors helps ensure consistency across your systems, even when assets change.
These measures can also be crucial for compliance. Types of Vulnerability Scanning and Detection Admins planning their vulnerability scanning strategy have multiple approaches at their disposal. Internal vs. Similarly, admins should test their network as a logged-in user to determine which vulnerabilities would be accessible to trusted users or users who have gained access to the network.
Comprehensive vs. Limited — A comprehensive scan accounts for just about every type of device managed on the network, including servers, desktops, virtual machines, laptops, mobile phones, printers, containers, firewalls, and switches. This means scanning operating systems, installed software, open ports, and user account information. Additionally, the scan might identify unauthorized devices. Ideally, with a comprehensive scan, no risks go overlooked.
Whatever type of network vulnerability scanner you choose, look for a tool that accomplishes some or all of the following functions, depending on your needs: Weakness detection — The first step of vulnerability scanning is to detect system weaknesses across the network. This could mean using a tool to try to catch and even exploit security gaps as it scans the attack surface.
Attempting to hack your own network is a proactive measure to ensure security. Some vulnerability detection tools are more targeted and work to identify missing software patches or firmware updates.
Vulnerability classification — The second step is to classify vulnerabilities, to prioritize action items for admins. Vulnerabilities could include packet anomalies, missing updates, script errors, and much more, and threats are typically prioritized by a combination of age and calculated risk level.
Many tools compare the security issues they discover to updated databases of known vulnerability risks, including the National Vulnerability Database and Common Vulnerabilities and Exposures.
Countermeasure implementation — Not all security tools both identify issues and give admins a way to automatically address them. Some VM tools are focused on monitoring exclusively, leaving it up to admins to take the next step.
But some are built to address device issues, like configuration errors, potentially reaching many devices simultaneously to save admins hours of work. These kinds of automated responses can be incredibly helpful for mitigating risks across large networks.
Paessler PRTG This tool provides thorough infrastructure monitoring, allowing admins to take stock of the network, applications, servers, and more. Rapid7 Nexpose This is a useful on-premises vulnerability management tool offering a decent starting point for security scanning. Tripwire IP Tripwire IP is an enterprise-grade internet network vulnerability scan software to not only scan all devices and programs across networks, including on-premises, cloud, and container environments, but also locate previously undetected agents.
ImmuniWeb ImmuniWeb is an AI-based platform offering several vulnerability scanning tools, such as ImmuniWeb Continuous to perform penetration testing to catch security threats and ImmuniWeb Discovery to detect and provide hackability scores based on your assets. Acunetix This is another website security scanner, rather than a network scanner. At the beginning of its service, the package scans your network to locate all endpoints, including IoT devices.
Syxsense creates an asset inventory from this information and also draws up a network topology map. Once all endpoints are logged, the protection service can begin. The network discovery process runs all of the time, so any changes to the asset inventory will automatically get logged and the network map also gets redrawn instantly.
Vulnerability scans trigger remediation actions with a companion patch manager providing the bulk of fixes needed to make all endpoints secure. Enrolled devices all need a Syxsense agent installed but the Syxsense controller in the cloud manages the installation of those programs.
The console gathers all statistics identified for each device, making system information available per device, per device type, and overall for the entire network. The security service is able to manage computers running Windows , macOS , and Linux. Features in the protection service include the ability to access each device remotely and there is also a Wake-on-LAN utility.
Most actions performed with Syxsense, though, are executed automatically. An example of this process automation is the link between vulnerability scanning and patch management. The audit logs are held on the Syxsense servers and each account gets an allocation of GB of cloud storage space. The Syxsense Secure system is able to support a range of strategies, allowing for detected software to be quarantined and identified by system alerts.
Threat remediation can be fully automated or reduced to a threat list for manual investigation. Syxsense offers a day free trial of Syxsense Secure. SecPod SanerNow Vulnerability Management is a cloud-based cyber-hygiene platform that includes security management tools for private networks. It lets you scan, detect, assess, prioritize and remediate vulnerabilities across network devices from the same console seamlessly.
The vulnerability scanner in his package of tools is the key service that triggers other functions and supplies system management tools with asset data. The scanner operates periodically, probing vulnerabilities on endpoints running Windows , macOS , and Linux. The vulnerability manager probes devices to check on all ports and also checks all of the settings of the operating system.
It examines the version of the operating system, which tells the scanner its patch status. Tests continue to search through for all software and identify the version numbers of those packages. All of this information is passed through to an asset manager , which maintains a software inventory.
The vulnerability manager can be set to perform scans at a frequency of up to every five minutes. The weaknesses that the vulnerability scanner looks for are dictated by a SCAP database.
The remediation processes of the vulnerability scanner are implemented by the patch manager of SanerNow. The patch manager interfaces with the software inventor and the vulnerability scan results and then accesses the sites of each software and operating system supplier to get patches and updates. The patch manager copies over the installers of these systems and then applies them at the next available maintenance window.
As it is a cloud-based system, the main processing service of SanerNow is hosted for you. This SaaS package includes a comprehensive dashboard , which gives administrators access to the system settings for the monitoring service and also screens of data and action results.
All information in the dashboard gets automatically updated every time the vulnerability scanner runs. All of the functions of SanerNow log and document all of the system and all of their actions thoroughly. The reporting feature of the package includes summaries of this data and stored logs are very useful for standards compliance auditing. The platform for SecPod SanerNow is a subscription service. Instead, the Sales Department negotiates a price with each new customer individually.
The best way to get to know the SanerNow service with its vulnerability scanner is to access a day free trial. The full list of features of this tool is only available to the paid version of the utility, which is designed for large LANs and multi-site networks. The free version is suitable for small and middle-sized enterprises and it will protect up to 25 devices. The free version gives you both on-demand and scheduled network vulnerability scanning that will detect issues with your in-house network.
The advanced technology deployed in the scanner can detect anomalous behavior. This strategy is more effective at identifying zero-day vulnerabilities than conventional rule-based threat database-driven detection systems.
You also get threat mitigation actions built into the free edition of Vulnerability Manager Plus. System and security threats may lie in weak configuration security or out of date software. Vulnerability Manager Plus includes Configuration Management and Patch Management functions that close off these weaknesses.
The vulnerability scan will highlight misconfigured devices and enable you to roll out standard configuration policies. The scan also checks on software versions and lets you automate patch installations. You get the option of which patches to rollout, letting you skip versions in cases where essential customizations could be lost through automated software updates.
These configuration and software monitoring capabilities extend to web servers and firewalls. The scanner will identify risky software installed on your equipment and automatically remove unauthorized or unadvised installs. System administrators get special tools in a dashboard that enable them to extend the basic capabilities of the vulnerability manager. These extend to the integration of Active Directory authentication.
The utilities available on the dashboard can be tailored according to the administrator role, which enables team managers to limit the functions available to individual technicians.
Powerful actions available through the dashboard includes Wake-on-LAN and shutdown capabilities, which can be set as automated mitigation processes or commanded manually.
Management reports and system audit recording are included in the Vulnerability Manager Plus package. The free edition of the package includes almost all of the capabilities of the two paid versions, which are called Professional and Enterprise editions.
You can get a day free trial of either of the two paid versions if your device inventory is too large to qualify for the use of the free version. It is a unified infrastructure monitoring tool that covers networks, servers, and applications.
Any security assessment has to begin with a check on all of your existing infrastructure. PRTG discovers and monitors all of your network devices for status changes and alert conditions.
Network traffic monitoring provided by PRTG can also highlight unusual activities that might indicate an intrusion. A packet sniffing sensor can be used for deep packet inspection, giving you data on the protocol activity in your traffic. This can be identified by port number or traffic source or destination, among other identifiers.
Network attacks leave a paper trail and gathering Syslog and Windows Event Log messages is step one in your vulnerability scan strategy. However, it does include some extra security assessment features, such as its port scanning and monitoring utility. Factors such as log message volume, log message severity, SNMP Trap data and port activity can all be included in custom alerts.
Paessler sets charging bands for PRTG that are based on the number of sensors that are activated. Every customer receives delivery of the full PRTG system, but with all of its sensors inactive.
You customize your implementation by activating the desired sensors. You can use PRTG for free permanently if you only activate up to sensors. You can get a day free trial of PRTG with unlimited sensors to check out its network protection features for yourself. You benefit from full user support, system updates, and security patches even while you are in the free trial period.

After that, running a Full audit enhanced logging without Web Spider gives you a good initial look at vulnerabilities on your site. You can look at the vulnerabilities status of a particular host or device.
Each vulnerability includes guidance for remediation. One big security flaw on your network is actually the condition of the computers connected to it. Software houses constantly look for security weaknesses in their products and produce updates to be installed by existing customers to close off any security loopholes.
These weaknesses are not the result of negligence when the software was originally written. They arise because hackers are constantly looking for new ways to use software features to breach security. Keeping track of the existence of new updates can be time-consuming, so a program that scans your computer and keeps a list of available updates will save you much time. The Verified plan has all of the features of the Pro plan and it also includes the services of human penetration testers.
The Intruder service is available for a day free trial. ManageEngine Vulnerability Plus is a vulnerability scanner that is bundled together with systems to help you fix the problems that the scan reveals.
