2024年6月18日 · The Canadian Centre for Cyber Security (CCCS). The guidance urges business owners of all sizes to move toward more robust security solutions—such as Zero Trust, Secure Service Edge (SSE), and Secure Access Service Edge (SASE)—that provide greater visibility of network activity.
Securing Wireless Networks - CISA
2021年2月1日 · What are the risks to your wireless network? Whether it’s a home or business network, the risks to an unsecured wireless network are the same. Some of the risks include: Piggybacking. If you fail to secure your wireless network, anyone with a wireless-enabled computer in range of your access point can use your connection.
a. In a direct network resource overload attack, the cyber threat actor overloads resources using tactics, such as exploiting a server vulnerability or inundating servers with requests. b. In a reflection amplification attack, the threat actor consumes network resources by reflecting a high volume of network traffic to the target. The actor
