Firewalls are a staple of perimeter-based security, but they’re reminiscent of a time when companies could trust that no malicious actors had access to their internal networks. However, these cybersecurity assets cannot effectively deter hackers that practice social engineering or exploit mobile devices.

In contrast, role-based access control and cryptographic segmentation go beyond the archaic perimeter-based information security strategy, assuming no user is trusted. How can these technologies address firewalls’ inherent vulnerabilities?

Why firewalls are no longer effective 

Today, people access company resources from any place with an internet connection. For hackers, it’s much easier to steal user credentials at a Starbucks, for instance, than it is to do so inside a corporate office.

Consider the following example. An worker opens her laptop on a train and uses a virtual private network to connect to her company’s customer relationship management system. Unbeknown to her, the person sitting next to her writes down her VPN login information. Now, the hacker can gain access to the woman’s business resources using her credentials. When he logs on, the firewall will register him as a legitimate user. Leveraging his position, he hacks into applications containing sensitive information.

How role-based access control reduces firewall vulnerabilities 

If a hacker uses legitimate credentials, a firewall won’t be able to stop him from accessing a corporate network. Few solutions can prevent cybercriminals from stealing passwords, but there are ways to limit their capabilities once they infiltrate business resources.

Certes Networks’ CryptoFlow solutions contains data breaches via role-based access controls and cryptographic segmentation. Through role-based access controls, IT can dictate which applications personnel are authorized to use based on their job requirements. Then, administrators can apply cryptographic overlays that prevent staff from using resources for which they do not have permission. These two technologies prevent hackers from moving laterally once they steal user credentials, preventing them from moving past low-value applications.
