Managed Firewalls

Jun 23, 2020 | Security

In today’s world, most businesses are digitising their management and operations systems and moving their assets and data into cloud. Though this comes with many benefits, the risk to your organisation of intelligent, orchestrated cyber-attacks – particularly against small to medium-sized organisations – greatly increases

As company assets and data move online, the risk and harm caused by modern, intelligent attackers has escalated. Now, more than ever before, both data stored long-term and data in transit need protection from intrusive attacks such as viruses, worms, and phishing scams.

Nowadays, businesses depend so heavily on web-based solutions and their distributed network infrastructure. These are evolving so rapidly that the conventional defence mechanisms which were employed a few years ago have now become insufficient. Where attacks used to be short-term and opportunistic, they now take the form of more persistent, well-developed and critical strikes. Successful, present-day attacks are structured according to an Intrusion Kill Chain, whereby attackers learn about your organization, prepare a bespoke attack, and deliver weaponised code to your systems, before exploiting or compromising them.

Unfortunately, successful attacks are usually detected too late, by which point valuable data has already been compromised. Therefore, it is crucial to identify attacks before the threat infiltrates the system. This highlights the importance of perimeter security which is the first mechanism used to detect and block attacks. Managed firewalls provide such security by stopping viruses and malware from entering a distributed system. This is key to data security as taking a multi-layered approach to safeguarding both your company’s data and its resources will greatly reduce your vulnerability.

Digital Defence with Managed Firewalls

Firewalls are key to intrusion prevention as they provide the first line of defence. They can be implemented with hardware, software or preferably both and are responsible for controlling the access of network-connected devices. The restrictions imposed by firewalls are vital to the protection of data which enters and exits your organisation. These restrictions automatically block access to websites which pose threats and halt the injection of dangerous malware. The use of firewalls ensures that data only passes to and from trustworthy sources on the internet, while limiting access to websites which may negatively impact staff efficiency. In essence, a firewall acts as a virtual barrier keeping threats at bay whilst allowing safe interaction and communication with other connected devices outside your network.

The barriers created by firewalls, however, must be tailored to the unique and varying needs of individual businesses.Firewalls are rendered useless if treated as a “one-size fits all” solution.Software firewalls provide some protection for the device on which they are installed but do not cover the range of other devices (and vulnerable points of access) like printers, cameras, and smart technology. Similarly, hardware firewalls will only filter the threatening traffic it is currently aware of. As hackers find more innovative ways to access your internal network, the list of threats which need to be blocked changes regularly and requires frequent updates. These updates are unfortunately made infrequently by internet service providers thereby creating vulnerabilities for opportunistic hackers to exploit.

This highlights the importance of managed firewalls. Although box-standard firewalls may provide decent protection to an individual, a more rigorous approach is required for organisations with multiple users and greater data flow. This is especially true for businesses which are concerned about protecting valuable client and organisational data. Managed firewalls block threats and control access for all users over multiple devices. But beyond controlling access (by making use of exhaustive updates of known web-threats), managed firewalls can be used to monitor traffic to detect abnormalities indicative of an impending attack before it happens.

Maintaining a Managed Firewall

Naturally, managing a firewall which spans more than a few computers with varying permissions can quickly become a nightmare for inexperienced users. Managing a robust, impenetrable firewall usually requires a dedicated team of professionals to oversee regular maintenance, constant threat-monitoring and updates of the types of attacks to block.

For a medium-sized business, managing such a firewall can drain company resources as the time invested in network security, while not wasted, is significant. It is common for multiple firewalls to exist throughout a network and the associated maintenance thereof increases with each additional device or staff member. Without an experienced security team overseeing this line of defence, the likelihood of security breaches, illegal access or data compromises increases.

For ultimate peace of mind, managed firewall services should be outsourced to expert teams which will eliminate the burden of enforcing advanced network security.

Glossary of Terms:

  1. Phishing – A scammer tricks you into you giving them your information. Typically it looks like an email from your bank asking you to reset a password or equivalent.
  2. Firewall – Like it sounds, this sets up a digital “wall” between your information and the hackers that want to exploit it.
  3. Perimeter security – Using firewalls and other methods, it stops attacks from entering a company’s server/website/data at the outset.
  4. Viruses – A computer virus is typically a malicious attack by a hacker who wants to get access to your computer/server/website so they can do damage. Often it takes the form of an attachment to an email that if downloaded, and worse, opened and executed it can do severe damage. What is problematic is that a virus could be operating in the background without your knowledge.
  5. Malware – Much like a virus, malware is like software, but malicious. So an app, or file that executes (is made to run/work), that does damage.
  6. Data security – Keeping your data safe regardless of device, or on a local server or in the cloud.
