What are Network Vulnerability Scanners?

Firewalls control incoming and outgoing network traffic based on defined rules. They serve as a barrier between an internal network and the Internet, monitoring and controlling connections according to established security policies.

IDPs monitor network traffic and alert administrators to suspicious activities, such as port scanners, malware, and violations of system security policies. However, IDPs do not actively stop attacks; instead, they rely on humans or applications to review alerts and decide on appropriate responses.

Similar to IDPs, IPSs monitor network traffic and raise alerts when they detect suspicious activities. Unlike IDPs, IPSs can automatically block or remove malicious traffic, thereby preventing attacks from reaching the network.

Network vulnerability scans can detect potential security weaknesses such as out-of-date software, misconfigurations, open ports, and other vulnerabilities that could be exploited by attackers[1]. By identifying these weaknesses early on, SMBs can take steps to address them before they are exploited.

Many industries have regulations that mandate regular vulnerability scans to ensure compliance. For instance, the finance industry must comply with regulations like those from the SEC, which may require regular vulnerability scans to protect client data[1]. Conducting regular scans helps SMBs adhere to industry regulations, avoid fines, and safeguard their clients' data and reputation.

Vulnerability scans can detect potential security issues early on before they are exploited by attackers[1]. This early detection allows SMBs to mitigate these issues promptly, reducing the risk of data breaches and other security incidents.
