Minhas dúvidas são sobre os sinalizadores exibidos pelo AIDE para cada arquivo nos relatórios diários por email. Por exemplo, para novos arquivos, é mostrado o seguinte:
f++++++++++++++++: /var/cache/apt/archives/squashfs-tools_1%3a4.4-1ubuntu0.1_amd64.deb
Posso deduzir que fsignifica arquivo e vi do que significa diretório. Mas que outras bandeiras podem vir aqui? E quanto ao ++++++++++++++++, isso significa alguma coisa?
Agora as coisas são mais interessantes para arquivos modificados:
d =.... mc.. .. : /run/motd.d/fwupd
f =.... mci.... : /run/motd.d/fwupd/85-fwupd
f >b... mc..C.. .: /var/cache/apt/pkgcache.bin
f <.... mc..C.. .: /var/cache/apt/srcpkgcache.bin
f =.... .c..... .: /var/lib/PackageKit/transactions.db
Não consegui encontrar nenhuma documentação com detalhes sobre o que isso significa. Qualquer ajuda para entender isso é muito apreciada.

Os sinalizadores são descritos na aide.confpágina de manual (consulte man 5 aide.conf):
report_summarize_changes (type: bool, default: true)
summarize_changes (DEPRECATED, will be removed in a future release)
Summarize changes in the added, removed and changed files sections of the report.
The general format is like the string YlZbpugamcinHAXSEC, where Y is replaced by the file-type (f for a regular file, d for a directory, l for a symbolic link, c for a character device, b for a block device, p for a FIFO, s for a unix socket, D for a
Solaris door, P for a Solaris event port, ! if file type has changed and ? otherwise).
The Z is replaced as follows: A = means that the size has not changed, a < reports a shrinked size and a > reports a grown size.
The other letters in the string are the actual letters that will be output if the associated attribute for the item has been changed or a "." for no change, a "+" if the attribute has been added, a "-" if it has been removed, a ":" if the attribute is
ignored (but not forced) or a " " if the attribute has not been checked. The exceptions to this are: (1) a newly created file replaces each letter with a "+", and (2) a removed file replaces each letter with a "-".
The attribute that is associated with each letter is as follows:
o A l means that the link name has changed.
o A b means that the block count has changed.
o A p means that the permissions have changed.
o An u means that the uid has changed.
o A g means that the gid has changed.
o An a means that the access time has changed.
o A m means that the modification time has changed.
o A c means that the change time has changed.
o An i means that the inode has changed.
o A n means that the link count has changed.
o A H means that one or more message digests have changed.
The following letters are only available when explicitly enabled using configure:
o A A means that the access control list has changed.
o A X means that the extended attributes have changed.
o A S means that the SELinux attributes have changed.
o A E means that the file attributes on a second extended file system have changed.
o A C means that the file capabilities have changed.
