New Effective Network Firewall Security
Promotion in Association with Perimeter 81
Firewalls are a truly legacy cyber security solution, so much so that the name has its origins in physical old-world security: these were steel doors meant to physically keep fires that started in one part of a building, or a ship’s hold, from spreading into other compartments.
Without it, your network is open to threats. A firewall keeps destructive and disruptive forces out, and controls the incoming and outgoing network traffic based on security parameters that you can control and refine. Today’s firewalls do the same with networks, putting digital barriers between network resources so that one exploit or breach doesn’t affect all the critical tools used by an organisation.
While this is effective when all resources are on the same “ship,” installing a firewall between different ships presents a challenge for security professionals. To help IT efficiently create a firewall for traffic across network resources in many different cloud environments as well as on-premises, Perimeter 81 has launched Network Traffic Control (NTC). NTC is a cloud-based firewall or Firewall as a Service, enabling easy, centralised control of traffic between sources and destinations on any network.
These firewalls help to protect networks and the devices operating on them from a wide range of security risks, namely unauthorised access from outside your customers' networks. They can also inform you of potentially threatening attempts to connect from within customer networks.
Firewalls are software or hardware that work as a filtration system for the data attempting to enter your computer or network.
Firewalls scan packets for malicious code or attack vectors that have already been identified as established threats. Should a data packet be flagged and determined to be a security risk, the firewall prevents it from entering the network or reaching your computer.
Network Traffic Control allows Perimeter 81 admins to easily create policies that apply to your Perimeter 81 network resources and that enforce traffic control in your network based on user groups, addresses, devices, servers, network addresses, ports and geolocation.
Using the new Network Traffic Control feature, you can segment Layer 3 and Layer 4 access to specific user groups and identities, using network policy rules that provide granular control of how data flows in these layers. You can use NTC to create traffic filtering rules for accessing network objects including IP addresses and services such as Telnet, HTTP, FTP, and RDP for comprehensive control of traffic between every local and cloud resource in your network. For example, you can make a rule to deny traffic from the user group ‘Contractors’ to your developers’ FTP server.
NTC works in tandem with two crucial security concepts, encrypted tunneling and custom access rules based on user identity. The users and groups to which NTC rules apply are easily set up for your network, and can be defined based on the qualifiers relevant to your organisation’s security, OS, device type, role, location, and much more.
Network Traffic Control rules further strengthen and define the security posture of organisations that already take advantage of Perimeter 81’s other security features.
Network Traffic Control user-based access management combined with Perimeter 81 encrypted tunnels provides Firewall as a Service utility for your organisation, so that you can design security with a scalpel, rather than with a hammer, enjoying more precise and autonomous control over your network.
Organisations that are not yet Perimeter 81 customers may recognize that managing their network policies based on IP addresses or service ports rather than on users no longer meets the needs of growing companies.
Any organisation must manage a network with multiple levels of trust, countless roles, and an ever-growing list of cloud resources and devices. This growing complexity requires an easy way to manage user- and role-based access as well as a top-down view of access, traffic, and activity. At Perimeter 81 we continue to add new security and networking features for our customers.
