3 Introduction Importance of Network security Internal Security External Security Purpose of GFI LANguard Enable Network admins to perform Security audit Remote system analysis
4
4 Features Security Audit Results in a verbose manner Flexible scanning Scan one computer Scan range of computers Scan list of computers Domain specific scan
5
5 Features (Cont…) System detection SNMP, NETBIOS queries, Ping Sweep Configuring ports for port scan
6
6 Features (Cont..) Enumeration of entry points SNMP holes CGI holes Open shares Rogue, Backdoor users Weak network passwords
7
7 Features (Cont…) Alerts Well known security problems are clearly identified Intelligent scanning Listing of hot-fixes & service packs
8
8 Features (Contd..) Remote Machine shutdown Exploitation of NetBIOS vulnerability Enabling auditing Sending spoofed messages Scheduling scans & automatic update of scans Gathering information & displaying using report generator
9
9 Features (Contd..) Scripting Language: LANS: LANguard Scripting language GFI LANguard contains its own scripting editor Allows users to create custom script which will be executed on the remote host as when accessed
10
10 Features (Contd..) Tools: SNMP Walk By performing SNMP walk potential hackers or malicious users will get lot of information about the system
11
11 Features (Contd..) Tools (Contd..) Trace route DNS look up
12
12 Tools (Contd..) SNMP Audit SNMP audit allows to detect weak community strings.

22 Results (Contd..) Script execution: hostname = "agardel2" # my desktop computer // name of the system from which the script is running ip = dnslookup(hostname) // using the function dnslookup if ip <> "" echo("hostname: " + hostname) echo("resolved as: " + ip, _color_blue) # now backwards:) hostname = ReverseDnsLookup(ip) if hostname <> "" echo("back to: " + hostname,) end if else echo("unable to resolve " + hostname + " !", \ _color_red) end if
