What Visibility Should Mean to You

Cyber security threats continue to grow. This evolution is seen in the sheer numbers of attacks, as well as the sophistication and complexity of attacks. Hackers are better funded and armed with more tools than ever. Hacking tools used for high-level security breaches, data theft and corruption, ransomware, and the infiltration of malware are readily available to hackers on the Dark Web. Shouldn’t your security tools be just as advanced, comprehensive, and powerful?

IT professionals often toss around the term ‘visibility’. Better visibility into the network, better visibility of systems and applications, better visibility of the end users and their devices, etc. But visibility should mean far more than simply the ability to see what’s going on in your network right now. It ought to mean visibility into the past, present, and even the future of your network and systems. Here’s what a comprehensive, fully-visible, network monitoring tool can do for your IT infrastructure.

What Has Happened in the Past


‘Leaving the past behind’ isn’t the best course of action when it comes to network security. You need to understand what happened in order to build better measures to stop similar events in the future.

Usually, a network that has been hacked once is likely to be hacked again. Once a vulnerability has been discovered, hackers will exploit it repeatedly, sometimes to get more information from an easily accessible source and other times simply for the fun of it. That’s why it’s important to have 100 percent visibility into what has already happened. Exactly what vulnerabilities were exploited? What can be done to close those network security gaps? Explore areas like software and firmware that wasn’t kept updated, user training issues, whether an inadequate mobile use policy played a part in the attack, and other potential lapses in network security.

What Could Happen in the Future

‘What could happen’ is why IT invests so much in firewalls, antivirus and antimalware protection, and other preventative measures. These are your preventative maintenance tools that stand in the way of overt and predictable attacks. The problem is depending on these tools to prevent all attacks, instead of continually assessing your vulnerabilities when it comes to sophisticated hacking tools and techniques that know how to subvert modern protective measures.

What is Happening Right Now


Network monitoring allows you to gain visibility into network traffic so that you can detect and stop any intruders that have manged to make their way around your security measures.

There’s a cat-and-mouse game that has played out between the ‘good guys’ and the ‘bad guys’ for millennia. The good guys get better protective weapons, then the bad guys get better attack weapons, forcing the good guys to up their game once again. It played out in the days of train robbers, during the Cold War, and it’s happening again in the arena of cyber security. That’s why strong network monitoring tools are so essential. Antivirus software and firewalls are like locks on your doors — these tools prevent someone waltzing in without much effort, but they don’t stop those willing to put forth the effort to get around those barriers. Network monitoring is how you catch the savvier villains once they’ve made their way past your gates and locks.

What Happens Following a Network Security Breach

“After action” is as critical as anything you do before an attack. An after-action plan is multifaceted. It includes cleaning up the mess left behind after an attack, but it also focuses on collecting forensic evidence of the attack. That forensic evidence can be used to help stop future attacks, but might also be crucial for bringing the hackers responsible to justice.
