Security focus has shifted from what is being taken from businesses to how attackers are gaining access to enterprise systems. Symantec notes “the number of breaches rose 23 percent” and “there was a 26 percent increase in malware” from 2013. With five out of every six large companies being targeted by attacks, security professionals need to know how hackers are getting in.
If you want to protect your enterprise network and assets in 2015, you’ll need to understand the latest threats and breaches and how they affect vulnerable companies.
Cyber attackers grow more sophisticated every day, throwing the cyber security landscape in flux. To properly protect against the latest threats, you need to know what they are and where you are vulnerable. IT World says that these are the biggest threats to look out for in 2015:
Every company is susceptible to cyber attacks in 2015. No one is immune, not even companies with extensive security resources. Take a look at the major companies that have already been breached halfway through 2015:
Many organizations are running the risk of not properly protecting themselves from modern security threats. Security measures like firewalls can hurt network performance at times and 32% of IT pros avoid certain firewall features because of it. Disabling firewalls and other security measures just to save some network performance can cause massive damage in the wake of cyber crime:
Network downtime and performance concerns can be hazardous to any business, but disabling key security systems is not the way to fix it. With 55% of downtime caused by hardware failures and 22% caused by human error, it’s clear that there are bigger issues to tackle than disabling the preventative solutions you’ve put in place to prevent cyber crime. Take note of 2015’s biggest threats and breaches and start preparing for the world of cyber attacks.

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.
Heartbeat packet: a soft detection technology that monitors the health of inline appliances. Read the heartbeat packet blog here.
Critical link: the connection between two or more network devices or appliances that if the connection fails then the network is disrupted.
