Frequently Asked Questions: Report Descriptions
Incident Reports
The record of a firewall event inlcudes two key identifying
details — the time of the event and the Source IP address.
myNetWatchman aggregates the firewall events submitted by
all its Agents based on these details into "incidents".
myNetWatchman then assesses whether incidents seems to be
attacks based on the number of Agents reporting them, the
time between reports, the particular port and protocol being
targetted, and a host of other factors. Incidents that are
identified as attacks are "escalated", and an email
alert is automatically sent to the ISP responsible for the
attacker's IP address. Reports based on myNetWatchman incidents
can show us a lot of valuable information, including:
- Top Port Targets - This report
shows ports being targetted most heavily in the past 24
hours.
- Increasing Port Targets - A
relative increase in scan activity against a specific port
may indicate that a new trojan has been deployed, an existing
trojan is increasing in its proliferation, or a new vulernability
has been discovered with a known service. This report can
help identify and deal with new threats.
- Largest Attacks - Last Hour
- The size of an attack is based on a score that incorporates
many factors, including the number of agents reporting the
attack, frequency with which the attack is reported, the
number of times each agent reports the attack, and the nature
of the vulnerability being exploited.
- Largest Attacks - 7 days
- The size of an attack is based on a score that incorporates
many factors, including the number of agents reporting the
attack, frequency with which the attack is reported, the
number of times each agent reports the attack, and the nature
of the vulnerability being exploited.
- Incidents by ISP
- Considering attack data by ISP can help illuminate whether
a worm is systematically infecting hosts of that ISP. Note
that ISP attack data is not meant to be compared, as they
don't take into account the relative sizes of ISPs (100
attacks out of 10,000 subscribers is much worse than 100
attacks out of 1,000,000 subscribers).
- Resolved Incidents
- myNetWatchman sent out
1,022
alerts over the past 24 hours and recipients formally closed
5
incidents. But don't let the lack of responses fool you
— system managers are often very glad to get alerts
which pinpoint the source of their security problem and
normally follow up on them. To date, we've received formal
acknowledgement of
28
resolved issues.
- Look Up Incidents by IP Address
- Quickly look to see if a particular IP address is the
source of any attacks.
Agent Reports
myNetWatchman aggregates firewall data that is submitted
by
305
Agent submitting data from across the globe. If you're not
already participating, we encourage you to register
now.
myReports
Registered users can see reports that reflect trends in the
data they submit. These reports include:
- myIncidents
Events Today - A list hostile incidents that were identified
within 24 hours.
- myEscalated
Incidents - Firewall events reported by your system
which have been classified as attacks.
- myPending
Incidents - Firewall events reported by your system
which have not been classified as attacks. These may be
because they are "false positives", or because
they don't yet meet our threshhold for identifying them
as attacks (ie, number of agents reporting the event, timeframe
in which repeat events are reported, etc.)
- myResolved
Incidents - Attacks to your system that were formaly
resolved through specific notification by the attacker's
ISP.
- myFirewall Events
Per Hour - Shows the number of firewall events your
system reports on an hourly basis.
- myAgent Errors - there
are a number of reasons that firewall events from your system
might not be read. If you have a significant number of errors,
please consult this
page.
- myIncidents
from NetBlock - myNetWatchman can be configured to submit
firewall data reports based the range of IP addresses used
by your network. On-line configuration of this feature will
be available soon. If you are interested in using it now,
please send a note to support@mynetwatchman.com.
- IPWatch - Maintains a list
of IP addresses from which you have submitted data. If you
work on multiple machines, this can be useful to look up
their IP addresses from a remote location.
- Report a Possible Attack
- You can submit firewall event data using our webform even
if you don't have the myNetWatchman Agent installed.
