Unless you’re under a rock, you know that the WannaCry Ransomware cyberattack swept worldwide headlines last week.
Organizations scrambled to apply the latest Microsoft security patch to their computers to prevent the spread of the attack. It’s estimated that the ransomware attack hit more than 300,000 victims in 150 countries.
The purpose of this document is to show Immediate Insight users how to configure additional network interfaces from the command line.
Caution: If you connect both eth0 and eth1 to the same network/switch this will cause a bridge loop & connectivity problems, they must be on separate networks / subnets.
One use case would allow for a management and data networks to be on a different subnet.
Another use case is would be to use eth1 as a promiscuous mode packet listener without an IP address. Edit the files below adding the lines indicated.
** below is Immediate Insight configuration for a packet listener command, making use of the eth1 promisc port**
Edit the Packet Capture command in DataFlow -> Remotes to assign the eth1 interface. Do this by adding the –i eth1 to the command string (the default is eth0)
(echo ‘@@sourceFile:tsharktag’; sudo tshark -i eth1 -b filesize:5000 -b files:5 -w /tmp/tsjunk -t ad -T fields -e frame.number -e col.Time -e col.Source -e col.Destination -e col.Protocol -e col.Length -e col.Info -E header=n -E separator=, -E quote=d ‘not(host @@agentIP)’) |nc @@serverIP 3003;sudo rm /tmp/tsjunk*
So you’ve purchased a new firewall. Now what?
You’ve got to decide which access is allowed, which isn’t allowed and whether or not rules are compliant with internal and regulatory standards.
Things are running along smoothly and then the dreaded “change.” A user submits a new access request and the fun begins. Is this access necessary? Safe? Compliant? And what happens when it’s time to retire unused rules?
How Effective Security Management Can Help Teams Cover the Exponentially Increasing Gap between Technology & the Resources Available to Manage It
Security teams today are under tremendous pressure due to the rising frequency and impact of breaches and a business that wants to move faster and faster. The answer to both of these challenges has always been to add more technology and staff resources.
However, each new technology added creates complexity. More rules are created and more data is generated. As networks continue to evolve, this complexity will only grow. And while staff resources may increase, they will never match the exponential growth of technology.
FireMon calls this phenomenon The Complexity Gap and has set out to help security teams close it.
Join us for this webinar with Frost & Sullivan where we’ll explore the causes of “The Gap” and how workforce multipliers such as intelligence and automation help staff manage their security more efficiently and more effectively.
Helping Enterprise Security Teams Improve Resource Efficiency & Reduce Overall Risk Exposure
Firewall technology has come a long way since its initial, most rudimentary forms. Next-Generation Firewalls (NGFW) are the latest development, and organizations are accelerating adoption to the new technology. But NGFWs aren’t a fix-all solution.
