Cybersecurity is really just a numbers game—and the numbers are stacked in favor of the cybercriminals. Every day, the average company is subjected to hundreds, even thousands of attempts to penetrate their security system. Your security team doesn’t have the time or the resources to deal with each one individually. You have your firewall to protect you, but attackers can find ways around it, masking themselves with the myriad other requests for access that your system receives, and staying hidden until it’s too late.

Your network security system needs to stop thousands of potential attacks in order to stay safe, but they only need one to get through, to compromise your system. What you really need is more than just a better security system. You need a way to even the odds.

How Advanced Ip Filtering Works

Perhaps the best way to deal with IPs requesting access to your network is the same way you’d deal with a batch of job applicants: let the bulk of them self-select out before you even get to the vetting process. That’s where an Advanced Ip layer comes in.

Say an attacker uses 10,000 bots to try to access your system. Each of them works to guess viable passwords, and, given enough time, by sheer volume of their effort, they’re bound to hit on one that works. If a particular bot is discovered, its IP address can be placed on a Realtime Blackhole List, blocking it from access. But there are still 9,999 other bots, each with its own IP address, working to access your system. Tostop them, you’d need to discover and block each IP individually.PV310-Front-1.jpg

An Advanced Ip  layer, however, blocks in bulk, rather than by individual IPs. Say a large number of threats to your system are coming from Russia. You can choose to filter out all IPs from the Russian ports where attacks are coming from, denying them access en masse. Furthermore, Advanced Ip  filtering accounts for blocking specific IP addresses as they attempt to travel through your network by offering controls port-by-port.

And suddenly, those 10,000 bots are greatly reduced, simply by virtue of their location and targeted destination. Then, if the attacker wants to continue trying to break into your system, it becomes more difficult for them to hide, making them more visible to your security team.

Why Advanced Ip  Filtering is a Game Changer

An Advanced Ip  layer levels the playing field for your security team. Now, their task is to try and find the right country and the right source and destination port, as well as cross their fingers that they are not included in the inherent threat intelligence lists inside of the Advanced Ip  layer. In the cat and mouse game of network security, it sways things in the cat’s favor. Attackers have fewer holes and cracks to move through within your system, making them more susceptible to detection. {{cta(‘a9ecac34-12f8-4d04-8742-1db89ec9917c’,’justifyright’)}}

It also allows your security teams more time and resources to do their jobs properly. As we’ve mentioned before, network security teams have to respond to a mountain of alerts to potential threats every day, decide for each one whether or not the threat is real, and either grant or deny the requester access to your system. There simply isn’t time for them to give each potential threat the time and attention that it requires to make a proper decision.  Decreasing the volume increases the efficiency, allowing the network security team to be of better value.

With Advanced Ip  filtering, however, security teams now have to deal with much less traffic and far fewer alerts. This means that the few threats that do manage to sneak through can be addressed much more quickly, before the attacker has time to get through. The network environment is more secure, and your security team is better equipped to do their jobs.

Advanced Ip  layering is becoming more sophisticated and more effective all the time. It’s the first line of defense against attackers, and it’s also your most important one. With a high quality Advanced Ip filter, you can breathe easier, knowing that your network is that much more secure
