Many enterprises have built their cybersecurity around their firewalls. But increasingly, the firewall is losing favor in modern enterprises with apps and data on the cloud being accessed from devices and networks anywhere in the world.
The traditional cybersecurity tool is a network security device that monitors traffic to or from the network. It allows or restricts traffic based on a defined set of security rules.
Legacy firewalls: Blurring boundaries
The issue with this is that firewalls do not go far enough in securing your systems. By the nature of their operation, firewalls create boundaries around your network. Today, with enterprises using many interlinked networks, multiple IPs and cloud computing, boundaries are fading. As a result, firewalls are less effective.
Based on a recent study, businesses are increasingly mistrustful of firewalls. Over 60 percent of respondents stated that: (1) their legacy firewalls don’t prevent cyberattacks against critical business and cloud-based applications; (2) their legacy firewalls cannot contain a breach of their organization’s data center perimeter; and (3) their legacy firewalls do not enable enterprise-wide Zero Trust.
As Gartner puts it, Zero Trust is “useful as a shorthand way of describing an approach where implicit trust is removed from all computing infrastructure”.
In addition, legacy firewalls impact organization flexibility and speed to a large extent. It is hard to update security rules on the firewall, and the study found that on average, enterprises take as much as three weeks to update firewall rules to accommodate any update needed. This can have a crushing security impact. They also limit access control, with policies that are often not sufficiently granular.
For all these reasons, legacy firewalls are increasingly falling into disfavor with enterprises of all sizes.
Cloud Access Security Broker (CASB)
A traditional firewall stands between your network and a non-trusted network (for example, the Internet). However, cloud data and apps are hosted on the Internet and as a result, legacy firewalls are not very good at protecting apps and data on the cloud.
Just like a traditional firewall protects the trusted network against attacks, a CASB protects cloud assets (applications, data, platforms and infrastructure) against cyberattack. They act as a foundational cybersecurity tool and resolve many of the issues associated with legacy firewalls.
A cloud-hosted or on-premises software, a CASB acts as an intermediary between users and cloud service providers, and can secure SaaS, PaaS or IaaS environments. It provides visibility into application access, maintains logs of activity, and allows enterprises to modify and create policies that suit cloud infrastructure and assets. A good CASB brings together key elements of privilege access management (PAM), identity and access management (IAM) and identity governance and administration (IGA).
Identity and Access Management solution (IAM)
As many as 90 percent of businesses believe that an IAM is indispensable to their cybersecurity plans. An IAM offers device-level security. This helps plug the gaps left by legacy and CASBs. Through IAMs, enterprises can provide granular access control, with unique rules defined for each user and class of user.
IAM offers comprehensive password management support, in the form of password policy management and single sign-on (SSO) SSO allows users to create and remember just one set of credentials for a whole suite of applications. This reduces risk of password loss and noting the password in unsafe locations. With password policy management, businesses can define rules to create strong, secure passwords that are less prone to cracking.
User-friendly provisioning and deprovisioning makes errors less likely. IT administrators find it easier to remember to revoke access when employees leave the organization when deprovisioning can be done with a single click. This also secures cloud apps against unauthorized access.
In a very real way, identity is the new firewall. When the device is secure against unauthorized logins, business-critical apps and data are as well, whether housed on-premises or on the cloud.
