5 Questions You Need to Ask About Your Firewall Security

Typically, organizations assume of firewall security as a 1-and-carried out variety of option. They set up firewalls, then presume that they are “superior to go” devoid of investigating no matter whether or not these answers are in fact guarding their units in the very best way achievable. “Established it and forget it!”

Alternatively of just relying on firewalls and assuming that they will often safeguard their companies from cyber risk, executives will need to begin asking further inquiries about them. As with most places of small business, it truly is crucial to take a critical appear at every single solution that your group depends on for security. So, let’s crack down a few queries that you and your workforce really should be asking about firewall security to get a far more exact check out into your network protection posture.

1 — What does your team’s firewall awareness look like?

In buy to adequately company and maintenance firewalls, your team requires to have at least a baseline knowledge of how firewalls operate. It can be particularly critical to have an understanding of what a firewall can and cannot do. For instance, following-technology firewall solutions are developed to execute deep packet inspection, that means they appear into individual parts of facts that enter and exit your system – a “gatekeeper” for your systems, per se. They execute this functionality perfectly, but only when they can in fact see the details in the payload. This is getting to be much more and more tricky in the age of “encrypt-every thing”.

2 — Does your security group commit time knowing the “other side”?

Who is on the other side of malicious attacks? In buy to comprehend how to safeguard your network from harm, your workforce requirements to realize what – and who – they’re defending versus. The landscape of cyber-attacks has greatly adjusted above the earlier couple of many years, and destructive actors have accelerated in ability. With the progression in technologies comes extra effective and risky cyber-criminals.

Hackers in the 2020s have much more highly effective instruments than at any time right before, actually at their fingertips. They are clever people, pushed by instruments that value them tiny to nothing at all to obtain. As an case in point, credential stuffing attacks (getting a username and password from a single internet site, and attempting it out on other web sites to obtain further qualifications) can be executed effortlessly with a free, open up-supply device named OpenBullet.

Security groups want to consider all of this into account, as they consider their existing firewall solutions. They also need to take into consideration the truth that most future-technology firewall solutions pre-date a lot of of these potent hacking resources by 10-20 yrs, and have modified tiny around the earlier two a long time.

3 — Can your subsequent-generation firewall resolution genuinely encrypt and de-encrypt all of your information?

In contrast to 20 yrs back, when firewalls ended up 1st launched, nearly all details packets that vacation in and out of programs are encrypted. This implies that in buy for deep packet inspection to get the job done, your firewall demands to be ready to de-encrypt the data, glimpse via the contents for any indications of malicious action, and then, in numerous circumstances, re-encrypt them to adhere to modern-day compliance standards.

This can take an massive quantity of processing electrical power and time, so your firewall resolution not only requirements to have the capacity to encrypt and de-encrypt, but your system requires to have the bandwidth to assistance these activities. Even worse, modern encryption strategies driven by the world wide need for privacy, are earning it additional and far more hard to decrypt and re-encrypt info in the very first place.

4 — How numerous IP addresses can your firewall answer block?

As we have explored over, deep packet inspection in a globe of encrypted knowledge can be a time-consuming system, which can then turn into a roadblock for present-day rapidly-paced network environments. And mainly because of this, your firewall technology need to have a way to enhance deep packet inspections, in scenario de-encryption can’t occur in time and packets containing malicious payloads slip via the cracks.

The greatest way to make sure that nothing at all gets past your firewall unnoticed? By employing IP deal with filtering as well. Given that all targeted visitors is recognized by a special IP tackle, it is a uncomplicated way to capture any packets coming from (or going to) recognised malicious places and block them, without even needing to check out their contents.

But there’s an unfortunate fact about IP tackle filtering: most nicely-identified firewall security suppliers cite that their remedies can only recognize and block about 100,000-1 million IP addresses, at the incredibly most. There are tens of millions (or billions) of identified negative IP circulating in the environment appropriate now. That is mad, ideal?! We believed so way too, and developed ThreatBlockr as a solution that solely concentrated on IP deal with blocking to fill this apparent hole. Our alternative can help up to 150 million IPs and Domains – about 1,000 periods extra than firewalls can guidance. This is since we made ThreatBlockr specially for this use circumstance. Firewalls were not designed for this use situation – they have been built for deep packet inspection, which is a quite various engineering challenge.

5 — Is your group supplementing your firewall resolution with other security practices?

As highly effective as firewall options can be, they are only as powerful as the human beings at your business. No make a difference how vigilant and highly developed your security team’s initiatives are, if a single staff clicks on a phishing email url, all those endeavours could all be for nothing at all.

It is crucial to consider cybersecurity awareness coaching, correct together with security options these kinds of as firewalls. When your workers can avoid phishing techniques and create (and rotate) protected passwords, they will lead positively to your total security application, making your bought solutions all the additional helpful. When your IT crew is arduous about the timely installation of the most up-to-date software program security patches across your complete business enterprise software package ecosystem, your security posture will make improvements to immensely.

The bottom line: firewalls aren’t a magical, black box solution that can take care of all security flaws. Firewalls are obviously not a silver bullet. If they were, no one would be having hacked. Yet, listed here we are, in 2022, with new breaches and threats discovered just about every day. Firewalls have their location in a security team’s toolkit but want to be complemented with gap-filling alternatives, methodologies, and enterprise-large greatest practices. Only then can efficient cyber security certainly be realized.

For companies looking to realize what threats are having as a result of their present security stacks, ThreatBlockr presents a free of charge menace risk assessment to get a extensive network security audit.
