cacls
CACLS
  • Windows NT, W2000, XP
  • Displays or modifies access control lists (ACLs) of files
cacls3
CACLS
  • cacls /T /E /G administrator:F d:\users\*.*
    • Cacls will add Full Control for the adminsitrator account all files and subfolders in the Users folder of the D:\ drive.
  • cacls /T /E /R Everyone d:\users
    • Cacls will remove all permissions for the 'Everyone' group in all files and subfolders in the Users folder of the D:\ drive.
  • Be sure to use the /E switch when you are just making modifications to a specific account or group. Without the /E switch, your settings will replace the current security with only what is specified.

CACLS

Of course anything done using CACLS could also be done through the GUI.

nslookup
NSLOOKUP
  • Name Server Lookup
  • Windows NT, W2000, Linux, UNIX
  • used to resolve Internet names to IP addresses
  • default (no parameter) returns default name server address (windows) ; on Linux/UNIX enters conversational mode allowing lookups until you quit
traceroute
Traceroute
  • Tracert (windows) ; traceroute (Linux/Unix)
  • used to display all of the routers between two communicating Internet hosts
  • options:
    • -d don’t resolve addresses to host names
    • -h (m) max number of hops to search for target
    • -j (hostlist) loose source route along the host list
    • -w (timeout) wait (timeout) msec for each reply
slide10
xmtr
  • LINUX version of traceroute
  • requires superuser authority
  • GUI application
slide11
ping
  • Send an ICMP echo request message to a specific host
  • plat form differences
    • Linux - no parameters, sends repeated /continuous requests until terminated
    • Windows - -t switch send continuous pings
    • Unix (most) -s switch sends continuous pings
ws ping security analysis tool
WS-Ping – Security Analysis Tool
  • COTS (common Off The Shelf) IPSwitch
    • www.ipswitch.com
  • Verify connectivity to a particular device on your network
  • Quantitatively test data connections between your computer and a remote system
  • Trace the path to a network host or device
  • Obtain information on host names and IP addresses
  • Scan your network and list devices and network services
  • View summary information about a network host or device including the official hostname, IP address, and contact information (from the Whois database)
  • View Simple Network Management Protocol values as well as Windows network domains, hosts, and workstations
  • Search information (such as user's full names and e-mail addresses) available through LDAP
ws ping

SATAN
  • SATAN recognizes several common networking-related security problems, and reports the problems without actually exploiting them.
  • For each type or 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: correct an error in a configuration file, install a bugfix from the vendor, use other means to restrict access, or simply disable service.
