- Ask users to leave their machines on one evening. Check the firewall logs for traffic between, say, 2:00am and 4:00am. Any desktop with internet traffic at that time may well have spyware checking in -run snort with the bleedingsnort (bleedingthreats.com) malware and antivirus rules -load your local dns server with domains associated with spyware to loopback or redirect to a local apache web server. Then examine the server logs for hits. An example http://www.bleedingthreats.com/blackhole-dns/ --- Akashdeep Bhardwaj <bhrdwh@yahoo.com> wrote:
Hi,
I am looking for a low cost, simple implementation
for 250 systems with different OS (all types of
microsoft, linux, unix, solaris, mac...) connected
via L2 and L3 Cisco and 3com switches (most of these
switches are SNMP) having 5 VLANs to -
1. Detect if a port on particular switch (read
machine) broadcasts more that a threshold that I
define, to detect virus/spyware broadcasts.
2. Detect Spyware & Malware on the network.
Any help is appriciated.
Thanks in advance,
