Sentinel is a fast file scanner similar to Tripwire or Viper with built in authentication using the RIPEMD 160 bit MAC hashing function. It uses a single database similar to Tripwire, maintains file integrity using the RIPEMD algorithm and also produces secure, signed logfiles. Its main design goal is to detect intruders modifying files. It also prevents intruders with root/superuser permissions from tampering with its log files and database. Disclaimer: this is not a security toolkit. It is a single purpose file/drive scanning program. Available versions are for linux (tested on all current Slackware and RedHat releases), with Irix versions soon to be added on.
