Upgrading SourceFire module from 5.x to 6.x and recovery procedure

SFR Firmware packages download

Hardware failures happens. If you have active service contract you’ll get new device from Cisco with same hardware parameters. One thing you don’t know is which version of software will be installed. In almost all cases it’s not the one you are using. Installing new firewall firmware on ASA is not a problem but what if you’re running SourceFire Management Center version 6.2 but your device came with 5.x or 6.0 firmware on SFR module? Well, prepare for process that will take few hours – you need to perform recovery procedure which is one of the ways of upgrading SourceFire.

Most common cases when we have to use recovery procedure for SFR are:

  • Problems with booting the SFP module after upgrade performed from Firesight Management Center
  • First software installation on SFR (in example when we just put SSD drives in our ASA to get benefits from Sourcefire NGIPS)
  • Need to upgrade firmware but our module cannot be registered in Firesight Management Center due to firmware mismatch

Last case is the one usually happening when we get new device during RMA process. Each Firesight Management Center have list of compatible firmwares that are supported on modules and unfortunatelly backward compatibility is not full. If you run one of the most common version 6.1 or 6.2 you need to have your modules in at least 6.1 version. Recovery process require that whole memory is erased and new firmware installed.

How to add network device to Microsoft Operations Management Suite using syslog

How to add network device to Microsoft Operations Management Suite using syslog

Microsoft Operations Management Suite is nice, and in some cases free, tool to manage and search through logs. But it’s dedicated to Windows and Linux operating systems by default. In many environments, especially those most secure ones, huge amount of logs are generated by network devices. Firewalls placed on the edge between Internet and DMZ zone quite often are set up to log all denied connections. Those firewalls can produce significant volume of logs that need to be searched and analyzed. Microsoft Operations Management Suite seems to be perfect tool for that but there is no native support of such feature. But we can implement this doing small workaround. Let’s look how to add network device to Microsoft Operations Management Suite using syslog.
