Credential-free and Agentless Windows OS Detection & Fingerprinting
The vast majority of network scanning software packages require some type of credentialed access to remote devices to detect operating systems. However, using TCP/IP stack fingerprinting and other technologies, Slitheris Network Discovery can identify a wide array of operating systems without credentials or authentication, including Windows (and its Edition), Linux, iOS, and Android. Slitheris can even scan for other details related to the operating system such as Windows Uptime, Cold Boot Time, Time of Day and Domain/Workgroup names, and distinguishes between Domain and Workgroup types, all without needing authentication or credentialed access. This saves the time and frustration trying various usernames and passwords or having to visit PCs and servers in person. Managed Service Providers and other IT Providers will particularly appreciate this unique feature.
Device Type Identification & Detection Hints
Slitheris provides an educated guess of device type by gathering dozens of attributes from each device during the probing process and comparing them to a Device Type Definitions DB, similar to how anti-virus software detects viruses. Although this feature is currently experimental, new methods are in development to much more accurately identify many more types of devices.
Device Age Estimation
As network devices age, they can become less secure and use more power than their newer counterparts, not to mention have fewer features and be less manageable. Some organizations replace important network devices every 5 years or so and sometimes in-house documentation doesn't exist or has gotten lost over time.
Using algorithms derived from various sources, Slitheris has the unique ability to estimate the year any network device was made, requiring just a MAC address to do so. Although most accurate with popular brands such as Cisco, HP, Dell, Apple, Samsung, etc, it's also more accurate with newer devices made within the past year and older end-of-life devices 5 years or older.
More Device Names
While many IP scanners show IP addresses in place of Device Names, we designed Slitheris from the ground up to use at least ten different possible sources for deriving device names.
SMB Security
Due to the WannaCry (AKA NotPetya) ransomware that used the NSA's EternalBlue vulnerability in 2017, a special SMB (Server Message Block) security feature was immediately added to Slitheris. Not only will it show vulnerability status without credentials, it also detects if the computer is infected with WannaCry/NotPetya. In addition, this feature has the added value of also determining if SMBv1 and SMBv2 is enabled, as some may want to disable SMBv1 due to security concerns or verify either protocol is independently active.
