Cybersecurity standards

See here for cybersecurity-standards information from which might be obtained, insights into the security measures and processes helpful for an entity’s security.

Deep hardware hacking

Consideration of deep hardware-hacking attacks is probably an overkill for most individuals, sole traders and small businesses—have to draw the line somewhere. However, if you are interested in defending against such attacks, the Novena open-source computing hardware platform and other related information hosted here, may be of interest to you.

Cryptocurrency security

If you are interested in adopting security measures suggested for Bitcoin users, have a look at the Glacier protocol.

Using phones and computers as motion detector alarms

Phones and computers can be turned into motion detector alarms, by using their built-in cameras and other sensors, with apps such as the “Haven: Keep Watch” app. This could provide extra security during sleeping hours. Psychic phenomena, including phenomena that have been verified and accepted by the scientific community, might be able to induce a person to stay asleep or suffer amnesia whilst intruders enter premises and room whilst the person is asleep; technological measures such as loud alarms may be helpful to defend against such attacks.

Steganography: easy hiding of information in computer documents

White-on-white text in computer documents and emails can be used for hiding and sending security sensitive information. This might be both simple and effective for low threat models.
