The current cyber threat landscape is daunting, with attacks occurring so frequently that security experts recommend operating under the assumption that your network is already breached. Major cyber attacks \u2013 and the disruptions they cause \u2013 frequently make news headlines. The MGM hack<\/a>, LendingTree breach<\/a>, and\u00a0CDK Global attack<\/a> are just a few examples that affected thousands of people per incident and now have many organizations rethinking their resilience strategies.<\/p>\n

The zero trust security methodology outlines the best practices for limiting the blast radius of a successful breach by preventing malicious actors from moving laterally through the network and accessing the most valuable or sensitive resources. Many organizations have already begun their zero trust journey by implementing role-based access controls (RBAC), multi-factor authentication (MFA), and other security solutions, but still struggle with coverage gaps that result in ransomware attacks and other disruptive breaches. This blog provides advice for improving your zero trust security posture with a multi-layered strategy that mitigates weaknesses for complete coverage.<\/p>\n

Gain a full understanding of your protect surface<\/h3>\n

Many security strategies focus on defending the network\u2019s \u201cattack surface,\u201d or all the potential vulnerabilities an attacker could exploit to breach the network. However, zero trust is all about defending the \u201cprotect surface,\u201d or all the data, assets, applications, and services that an attacker could potentially try to access. The key difference is that zero trust doesn\u2019t ask you to try to cover any possible weakness in a network, which is essentially impossible. Instead, it wants you to look at the resources themselves to determine what has the most value to an attacker, and then implement security controls that are tailored accordingly.<\/p>\n

Gaining a full understanding of all the resources on your network can be extraordinarily challenging, especially with the proliferation of SaaS apps, mobile devices, and remote workforces. There are automated tools that can help IT teams discover all the data, apps, and devices on the network. Application discovery and dependency mapping (ADDM) tools help identify all on-premises software and third-party dependencies; cloud application discovery tools do the same for cloud-hosted apps by monitoring network traffic to cloud domains. Sensitive data discovery tools scan all known on-premises or cloud-based resources for personally identifiable information (PII) and other confidential data, and there are various device management solutions to detect network-connected hardware, including IoT devices.
