IPsec
- encrypts application layer data.
- provides security for routers sending routing data across the public intern-et.
- provides authentication without encryption, like to authenticate that the data originates from a known sender.
- protects network data by setting up circuits using IPsec tunneling in which all data is being sent between the two endpoints is encrypted, as with a Virtual Private Network(VPN) connection.
SHA
The Secure Hash Algorithms are a family of cryptographic hash functions
DES
The Data Encryption Standard is a symmetric-key algorithm for the encryption of electronic data. Short key length makes it too insecure
PSTN

Line Interactive UPS
- detects power changes/loss
- boosts or increase utility power
- mainly used in areas where utility power is clean
- less reliable than double conversion UPS
Double conversion UPS
These UPS systems provide your facility the highest level of protection by isolating the equipment from raw utility power. The system works by converting power from AC to DC and then back to AC.
