Riverbed2

The networking world is ever changing, with new monitoring and security tools entering the market, companies introducing exciting new technology, partnerships being formed to create disruptive solutions, and more. With so much note-worthy news, here are some of the most important news stories and updates in the industry this month and what that could mean for the industry as a whole. 

 


Spring Cleaning Your Network Security

Spring is the perfect time to dust off your network security policies, re-evaluate them, and gauge whether they are still effective. When using various tools to monitor, these is a rise of valuable data being collected and everyone becomes a potential victim of varied cybersecurity attacks. Even though it is impossible to build a network that is guaranteed 100% safe from intrusion, organizations must take necessary steps to address some of the most basic vulnerabilities such as preventive measures against breaches, keeping IoT devices secure, having firmware tools and hardening guides for technological partners and effectively managing product life cycles.  Read More

Heartbeats Packets Inside the Bypass TAP

If the inline security tool goes off-line, the TAP will bypass the tool and automatically keep the link flowing. The Bypass TAP does this by sending heartbeat packets to the inline security tool. As long as the inline security tool is on-line, the heartbeat packets will be returned to the TAP, and the link traffic will continue to flow through the inline security tool.

If the heartbeat packets are not returned to the TAP (indicating that the inline security tool has gone off-line), the TAP will automatically 'bypass' the inline security tool and keep the link traffic flowing. The TAP also removes the heartbeat packets before sending the network traffic back onto the critical link.

While the TAP is in bypass mode, it continues to send heartbeat packets out to the inline security tool so that once the tool is back on-line, it will begin returning the heartbeat packets back to the TAP indicating that the tool is ready to go back to work. The TAP will then direct the network traffic back through the inline security tool along with the heartbeat packets placing the tool back inline.

Some of you may have noticed a flaw in the logic behind this solution!  You say, “What if the TAP should fail because it is also in-line? Then the link will also fail!” The TAP would now be considered a point of failure. That is a good catch – but in our blog on Bypass vs. Failsafe, I explained that if a TAP were to fail or lose power, it must provide failsafe protection to the link it is attached to. So our network TAP will go into Failsafe mode keeping the link flowing.

Glossary

  1. Single point of failure: a risk to an IT network if one part of the system brings down a larger part of the entire system.

  2. Heartbeat packet: a soft detection technology that monitors the health of inline appliances. Read the heartbeat packet blog here.

  3. Critical link: the connection between two or more network devices or appliances that if the connection fails then the network is disrupted.
