### Cetus StormWindows

Cetus StormWindows&tm; for Windows 95 allows authorized users to add several types and degrees of protections to the desktop and system of a Windows 95 computer. Intelligent use of StormWindows security measures will allow secure use of any shared Windows 95 PC (a version for Windows NT 4 is under development). Examples of desktop protections include

- Hiding all desktop icons
- Hiding Start menu programs groups and links
- Preventing the saving of desktop changes
- Hiding all drives in My Computer
- Hiding the Start menu settings folders (Control Panel and printers) and taskbar
- Hiding Network Neighborhood

Some of the system protections include

- Disabling the MS-DOS prompt and the exiting to MS-DOS mode
- Preventing warm booting (Ctrl+Alt+Del)
- Blocking the running of Registration Editor and System Policy Editor
- Preventing the merging of REG files into the Registry
- Preventing the addition or deletion of printers
- Keeping the Documents menu empty
- Hiding sensitive Control Panel pages and settings

StormWindows security schemes can be imported from and exported to other computers by disk. StormWindows changes do not require the use of policies. StormWindows protections would probably be most useful to someone in charge of a number of computers at a school or business, a network manager, or a parent. Access to StormWindows is password protected.

### SATAN (Security Administrator's Tool for Analyzing Networks)

SATAN recognizes several common networking-related security problems and reports them without actually exploiting them. For each type of problem found, SATAN offers a tutorial that explains the problem and what its impact could be. The tutorial also explains what can be done about the problem. SATAN collects information that is available to everyone with access to the network. With a properly configured firewall in place, that should be near-zero information for outsiders. SATAN will inevitably find problems. Here's the current problem list:

- NFS file systems exported to arbitrary hosts
- NFS file systems exported to unprivileged programs
- NFS file systems exported via the portmapper
- NIS password file access from arbitrary hosts
- Old (before 8.6.10) sendmail versions
- REXD access from arbitrary hosts
- X server access control disabled
- Arbitrary files accessible via TFTP
- Remote shell access from arbitrary hosts
- Writable anonymous FTP home directory

System requirements: UNIX, at least 16MB of RAM, and 50mHz. Authors: Dan Farmer and Weitse Venema

### Strobe

Strobe is a network/security tool that locates and describes all listening TCP ports on a (remote) host or on many hosts in a manner that maximizes bandwidth utilization and minimizes process resources manner. Strobe approximates a parallel finite state machine internally. In nonlinear multihost mode, it attempts to apportion bandwidth and sockets among the hosts very efficiently. This can reap appreciable gains in speed for multiple distinct hosts/routes. On a machine with a reasonable number of sockets, strobe is fast enough to port scan entire Internet subdomains. It is even possible to survey an entire small country in a reasonable time from a fast machine on the network backbone, provided the machine in question uses dynamic socket allocation or has had its static socket allocation increased very appreciably (check your kernel options). Strobe is said to be faster than ISS2.1 (a high quality commercial security scanner by `cklaus@iss.net` and friends) or PingWare (also commercial). Author: Julian Assange

## NetWare

The following NetWare utilities are on the CD-ROM. This listing provides contact information for each company and a description of its product.

### SecureConsole

SecureConsole for NetWare is a fileserver console security application that adds a new level of control and accountability to the NetWare server. It restricts access for individual users or NetWare security groups to specific server commands or applications. SecureConsole also records the commands performed by each logon. SecureConsole acts like a screen saver on the console forcing the user to identify himself with a valid NetWare login and password. If the user is authorized to access the server, SecureConsole unlocks the screen but continues to verify the user's actions against his list of authorized functions and application screens. This means that different users or groups can have different levels of access. Installation of SecureConsole is simple! The software can be installed through the NetWare v4 product installation program or by copying the program to the server manually. No special NetWare queues, setup files, or license files are required, and the product is not serialized. This allows for software distribution products or batch installation to multiple fileservers.
