When the Tripwire program runs, it is compared with the snapshot. If no match is found, it reports that the system administrator file has been modified. Through understandi

Ossec has encountered a lot of problems in batch deployment, say two of them.1, key_gen.py the script can generate up to 1000 keys at a time, more than 1000 agents, need to generate more than a few times, as long as the IP corresponding to the correct key. The agent's name supports up to 32 characters, and more than 32 characters will cause an error.The script can add, remove, extract, import agents/root/ossec-hids-2.8.3/contrib/ossec-batch-manager.pl

I like the SD card because of the write protection switch. These two programs can search for known rooktkit, backdoor, and local vulnerability exploitation programs, and discover limited suspicious activities. The reason we need to run these tools is that they can view/proc, ps and other important activities on the file system. Although

: TripwireTripwire is one of the most well-known IDs implementations. Tripwire has compiled a database of system files and protected its configuration files and binaries with a set of keys. After the configuration of selections and exceptions is defined in detail, tripwire notifies them of any changes that occur to the files they monitor.Tripwire's strategy model is very flexible and allows you to shape its
