Keeping data and online activities secure is a top priority for technology managers today. Secure Access Service Edge, or SASE (pronounced "sassy"), is a popular method for protecting networks. It combines important security measures to protect data as it moves through digital spaces, ensuring that both major companies and smaller businesses stay safe and efficient.
Understanding SASE and Its Role
SASE is a cloud-based solution that integrates essential network security functions. For technology managers, understanding each part of SASE helps in effectively managing and safeguarding an organization’s digital architecture.
- WHO benefits: Technology managers looking to streamline their security processes.
- WHAT it involves: A set of integrated security controls via a cloud-based platform.
- WHY it's crucial: To reduce risks, boost efficiency, and save costs with comprehensive cloud security.
Key Components of SASE
- Software-Defined Wide Area Networking (SD-WAN): This enhances and controls how different parts of the network communicate. By using SD-WAN, you can prioritize important traffic and improve the performance of applications.
- Cloud Access Security Broker (CASB): A CASB acts as a security checkpoint between users and cloud service providers. It ensures data security by monitoring and enforcing security policies.
- Firewall as a Service (FWaaS): Unlike traditional firewalls, FWaaS delivers the same protection but from the cloud. This supports secure internet usage across all devices.
- Zero Trust Network Access (ZTNA): Assumes that threats can come from anywhere, so it limits network access strictly to authenticated users, minimizing potential breaches.
- Secure Web Gateway (SWG): Protects users from web-based threats by filtering unwanted software/malware from user-initiated web traffic and enforcing company policy.
The Value of Security Controls in SASE
Security controls are procedures and mechanisms enforced to protect digital data, networks, and infrastructure. When integrated into SASE, these controls:
