Problems with NSM, such as its weak IPS forensics tools and its inability to create policies that include multiple zones, will be obvious to anyone building and managing large policies with UTM features. This linkage among all aspects of a policy makes it easy to understand what the firewall is going to do, and why. NSM is a single application that combines firewall and IPS management, forensics, monitoring and alerting that allows traffic through the firewall with all the NAT and UTM features that apply to that policy. NetScreen Security Manager (NSM), the tool used to drive the firewalls that Juniper picked up with its NetScreen purchase three years ago, also has matured considerably since it was introduced. Don't even think about linking IPS analysis (which requires a separate application and separately purchased Monitoring, Analysis and Response System appliance) to policy management, because it just doesn't work that way. Now you've got two management tools pointed at the same firewall, raising the potential for conflicting policy updates. Instead, it launches the per-device management tool, which has good status information - but can talk to only one firewall at a time.
For example, CSM can't show you performance, errors and status information.
In other places, Cisco seems to have forgotten to put features into its central management. It is disconnected from firewall policy and is so confusing that even the gurus from Cisco who helped us with our installation got it wrong.
Utm device code#
In some cases, that's good in others, it's not as good, because some of the ugliness of the structure of the old PIX code is being carried forward. CSM derives a lot of its structure from the underlying firewall, so someone who is familiar with the ASA or PIX ,Cisco's older stand-alone firewall product, will be able to understand what CSM is doing.
Utm device how to#
This configuration is not directly supported by the firmware so please consult your Sophos support representative in order to get this set up if you are unsure of how to configure the device in this way.Of course, perfection is not yet upon us. Note: The commands entered above will clear out upon a reboot of the Sophos UTM so you will need to enter these each time a reboot has occurred or create a cron job in the config to re-apply these commands upon start up. If the "ip_conntrack_udp_timeout" and "ip_conntrack_udp_timeout_stream" are not showing as 180 seconds then the following commands will apply this change: Type the following command to show the current configuration: Using either SSH or putty, terminal into the device and log into the console. Once logged in to the Sophos go to Network Protection > VoIP and make sure that SIP Protocol Support is switched to off. > Input the following > Name = "Cytracom Pool" Interface = WAN Position = Top Bandwidth (kbit/s) = Traffic Selectors = Check both Cytracom IN and Cytracom Out Comment = Optional. Once in the QoS Settings go to the Bandwidth Pools Tab. Once logged in to the Sophos go to Interfaces & Routing > Quality of Service (QoS). Press Save, then find the new rule in the list and click the slider to enable it. > Input the following info > Name = "Cytracom Out" Type = Traffic Selector Source = Any Service = Any Destination = "Cytracom" Comment = Optional Open the Advanced sections and input the following > TOS/DSCP = DSCP-Bits DSCP-Bits = DSCP Value DSCP Value = 46 Amount of data sent/received = unchecked > Helper = None. Once in the QoS Settings go to the Traffic Selectors Tab. Setting up Outbound Traffic Selectors for QOS:
> Input the following info > Name = "Cytracom IN" Type = Traffic Selector Source = "Cytracom" Service = Any Destination = Any Comment = Optional No Advanced Configuration Needed on the inbound because it will not retain the DSCP coming back. Setting up Inbound Traffic Selectors for QOS: > Input the following info > Name = "Cytracom" Type = Range IPv4 From = 209.105.249.194 IPv4 To = 209.105.249.252 No Advance configuration Necessary. Once logged in to the Sophos go to Definitions & Users > Network Definitions > New Network definition. Setting up the Cytracom Network Definition: Then under "Global ICMP Settings" check the box next to "Allow ICMP on Gateway" then press "Apply". When in the general Firewall settings go to the tab ICMP. Once logged in to the Sophos go to Network Protection > Firewall. Important: Make sure device firmware is always up to date.
