Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
Reinstall macOS on an Intel Mac from Recovery with Command-R or a createinstallmedia USB. macOS Tahoe 26 is the newest version any Intel Mac can run.
Install Ubuntu 26.04.1 LTS from ubuntu.com: verify the ISO, save your BitLocker key, shrink Windows, keep Secure Boot on, use a VM on Apple silicon Macs.
USB grew from 12 Mbps in 1996 to 80 Gbps in USB4 v2; Thunderbolt from 10 to 80 Gbps. Here are the dates, the naming mess and the DMA attack history.
Cold boot (2008) showed DRAM keeps secrets after power off; Rowhammer (2014) showed it flips bits. The dated history, and what actually mitigates each.
Attackers read traffic by reaching the medium: a cable tap, a switch, a radio or an upstream link. TLS, encrypted DNS and WPA3 hide content, not metadata.
Get the ISO from the OS vendor, check its signed checksum, then write it with the vendor's tool or dd after confirming the device. Every OS covered.
Download Windows 11 only from Microsoft, confirm TPM 2.0 and Secure Boot, check the ISO's SHA256, build a USB, then clean install and lock down first boot.
TCP and UDP send every header in plaintext, so anyone on the path can read and alter them. TLS 1.3 and QUIC encrypt data, but IPs and ports stay visible.
Not completely. With the Find My network on, a supported iPhone can be located for up to 24 hours after power off, or 5 hours in power reserve mode.
