¶ Introduction
The Network Security Monitor (NSM) is a module of blësk Network Monitoring tool for vulnerability management of IT infrastructures.
It assists business organizations with automated and integrated vulnerability assessment and management. Its task is to discover vulnerabilities and security gaps before a potential attacker does.
The scan feature of blësk NSM uses over 78,000 Vulnerability Tests (VTs) to detect existing vulnerabilities on the inspected network. The found vulnerabilities are evaluated based on their severity which enables the setting of priorities for eliminating the vulnerabilities.
The NSM discovers vulnerabilities through different perspectives of an attacker:
External
The blësk NSM can simulate an external attack to identify outdated or misconfigured firewalls.
Demilitarized Zone (DMZ)
The blësk NSM can identify actual vulnerabilities that may be exploited by attackers that get past the firewall.
Internal
The NSM can also identify exploitable vulnerabilities in the internal network, for example those targeted by social engineering or computer worms. Due to the potential impact of such attacks, this perspective is particularly important for the security of any IT infrastructure.
The NSM utilizes the Common Vulnerability Scoring System (CVSS). CVSS is an industry standard for the classification and rating of vulnerabilities. It assists in prioritizing the remediation measures.
See the Quick Start guide for examples on how NSM helps identify vulnerabilities and security gaps in your network.
