While we’ve looked at the state of cyber security in the healthcare, finance and insurance industries, it doesn’t begin to cover the breadth of threats out there. Industry-agnostic attacks are constantly threatening confidential corporate information and organizations of all sizes are falling victim to hackers. In fact, we’re all beginning to wonder – is data truly safe anymore?
Customer data isn’t the only thing of value residing in corporate networks. Intellectual property, legal records, emails, marketing plans and other proprietary documents – basically anything that sets your company apart or exposes your internal operations – should be considered vulnerable. In this part of the Data at Risk series, we’ll look at a few examples of corporate confidentiality cyber attacks, their ultimate effects on the organization and what you can do to mitigate your vulnerability.
These days it almost feels as if hackers are nearly unstoppable. Whether these attackers believe they have a higher purpose (hacktivists) or they are just looking for a fast payout, once they’ve set their sights on a goal they won’t stop until they’ve accomplished it. These are some of the corporate confidentiality attacks that happened recently:
If you don’t want to fall victim to a corporate confidentiality cyber attack, you need to be more prepared for the growing cyber threat landscape.
You can deploy all the security appliances you want, but they are useless if they can’t see 100% of your network traffic. Ensuring total network visibility is the first step toward true corporate confidentiality. Many companies think SPAN ports or built-in NIC cards will suffice for network visibility, but network TAPs are the only real solution.
The multitude of corporate confidentiality attacks has left the idea of privacy a bit laughable. However, deploying the right security appliances in tandem with network TAPs can make it a reality.

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.
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.

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