THANK YOU FOR SUBSCRIBING
Government CIO Outlook | Thursday, March 31, 2022
Malicious cyber actors are frequently opportunistic, focusing on networks with visible vulnerabilities and valuable assets as low-hanging fruit. Since government agencies possess data or other assets that malicious cyber actors desire, they are frequently willing to go to great lengths to obtain them.
FREMONT, CA: Government agencies must have a broad range of security capabilities to defend against any threat. They should, however, pay special attention this year to critical threat areas that malicious actors are ready to exploit.

The Digital Attack Surface Continues to Expand
As organizations adopt new technologies and operating patterns, malicious cyber actors are exploring and discovering new opportunities for exploitation. As agencies continue to expand their network infrastructure to support work-from-anywhere (WFA), remote learning, and new cloud services, the remote environment provides ample opportunity for malicious actors to discover and exploit vulnerability. Rather than focusing exclusively on an organization's traditional core network, threat actors are leveraging emerging edge and "anywhere" environments throughout the extended network, including assets that may be deployed in multiple clouds with varying security policies and capabilities.

Government agencies should prioritize the implementation of zero trust principles and architectures. Zero trust network access (ZTNA) is critical for moving beyond the outmoded 'moat and castle' network defense model or the relatively simple multifactor authentication and VPN connections that many government organizations used to secure their networks during the rise of remote work. Zero Trust must be applied more delicately—application by application—because access should not be evaluated and granted on a 'one and done' basis when a user logs on. This increases data protection and enables a 'work from anywhere' operating posture in which the new normal may include users, data, and devices connecting in increasingly innovative and non-traditional ways.
Additionally, software-defined networking (SDN) is becoming more prevalent, and secure software-defined wide-area networking (SD-WAN) is becoming more critical due to organizational flexibility, cost savings, and improved user experience. Secure SD-WAN can provide these benefits while also providing organizations with powerful and dynamic capabilities for segmenting networks and data access to limit an intruder's freedom of lateral movement and keep breaches to a smaller portion of the network.
