“The cyber threat is no longer limited to your office network and work persona,” the NSA said. “Adversaries realize that targets are typically more vulnerable when operating from their home network since there is less rigor associated with the protection, monitoring, and maintenance of most home networks. Home users need to maintain a basic level of network defense and hygiene for both themselves and their family members when accessing the Internet.”
