How Does SASE Work?
SASE is a network security framework that incorporates robust cloud security technologies, such as secure web gateways (SWGs), Firewall as a Service (FWaaS) and cloud access security brokers (CASBs). SASE uses those technologies to form a software-defined wide area network (SD-WAN), which provides maximum cloud security for all users and endpoints. It drastically reduces the risk of cyberattacks, providing protection and efficient access to critical areas of a school’s network.
SASE also recognizes devices and users based on a district’s security policy. This lets IT leaders take a proactive approach to their cybersecurity measures because they can assure secure access to staff and students at any location from any device.
SASE connects security capabilities and networking to a single service, cloud architecture. “It’s the idea of putting security at the service edge and putting the access as appropriately and efficiently as possible at the service edge,” says Peter Romness, cybersecurity principal for the U.S. public sector CTO office at Cisco.
How Does SASE Help K–12 Schools with Security?
SASE shifts the security focus from traffic flow-centric to identity-centric, providing secure data access to students, teachers and staff.
“SASE provides seamless connectivity everywhere, on the school campus and off the school campus,” says Romness.
By choosing the best path for data without compromising performance, SASE works as an upgrade to traditional VPNs. It implements security controls closer to the end user, rather than implementing secure parameters integrated across the network. It also integrates many security functions, including malware protection, DNS reputation, secure web gateway, zero network access, cloud access security broker and intrusion prevention.
SASE Benefits For K–12 Districts’ Security Posture
In addition to secure remote access, K–12 IT leaders will find other benefits when employing a SASE security model.
This model offers constant network monitoring capabilities, allowing IT teams to monitor data flow and analyze network performance in real time. K–12 schools can get a real-time visual representation of all outbound process connections on a single network interface.
With educational technologies expanding rapidly, students and educators need reliable ways to connect to the school’s network. SASE ensures everyone can connect to the network securely and reliably, and its architecture allows it to deliver data without any latency, offering a seamless experience to the end users.
Schools can also improve their return on investment with SASE security models. Whereas now, many K–12 schools use legacy security models as their network security solutions, SASE offers a single cloud-native solution. This eliminates the need for various solutions from different vendors that result in an overly complicated, inefficient and costly security model. Simplifying network complexity also leads to less workload on the IT staff.
Now more than ever, schools need modern solutions to secure their data. With the increased popularity of the cloud, remote distribution of data has skyrocketed, and so has cybercrime. SASE gives K–12 IT leaders the ability to maintain their priority of securing data and protecting users from threats.
