Ensuring email security might be one of the most important and most difficult tasks an administrator must face. Every day, servers process thousands of emails and controlling such a big mail flow is not easy. No wonder hackers focus on this channel when they plan attacks. They use various tricks to make users think that opening a suspicious attachment is a good idea.
One of the tricks they use is email spoofing.
Email spoofing is a very popular attack method. The sender modifies message headers so that emails appear as sent from someone else. Hackers use it, for example, to impersonate employees of a company to obtain login credentials, personal data, or other confidential information. Two most common ways to protect your organization from external spoofing attacks are:
Both ways give good results when fighting with external spoofing. The problem starts when we come across internal spoofing when one employee tries to impersonate a colleague. It might be a joke, or to achieve some benefits – either way, it can sabotage a company in a number of ways:

The key to safe database management is making regular backups. Depending on your data volume, number of MySQL servers, and database workload, you can use these backup techniques, alone or in combination: hot backup with MySQL Enterprise Backup; cold backup by copying files while the MySQL server is shut down; logical backup with mysqldump for smaller data volumes or to record the structure of schema objects. Hot and cold backups are physical backups that copy actual data files, which can be used directly by the mysqld server for faster restore.
Using MySQL Enterprise Backup is the recommended method for backing up InnoDB
data.
InnoDB
does not support databases that are restored using third-party backup tools.
The mysqlbackup command, part of the MySQL Enterprise Backup component, lets you back up a running MySQL instance, including InnoDB
tables, with minimal disruption to operations while producing a consistent snapshot of the database. When mysqlbackup is copying InnoDB
tables, reads and writes to InnoDB
can continue. MySQL Enterprise Backup can also create compressed backup files, and back up subsets of tables and databases. In conjunction with the MySQL binary log, users can perform point-in-time recovery. MySQL Enterprise Backup is part of the MySQL Enterprise subscription. For more details, see MySQL Enterprise Backup Overview.
If you can shut down the MySQL server, you can make a physical backup that consists of all files used by InnoDB
to manage its tables. Use the following procedure:
InnoDB
data files (ibdata
files and .ibd
files) into a safe place..frm
files for InnoDB
tables to a safe place.InnoDB
log files (ib_logfile
files) to a safe place.my.cnf
configuration file or files to a safe place.In addition to physical backups, it is recommended that you regularly create logical backups by dumping your tables using mysqldump. A binary file might be corrupted without you noticing it. Dumped tables are stored into text files that are human-readable, so spotting table corruption becomes easier. Also, because the format is simpler, the chance for serious data corruption is smaller. mysqldump also has a --single-transaction
option for making a consistent snapshot without locking out other clients. See Section 1.3.1, “Establishing a Backup Policy”.
Replication works with InnoDB
tables, so you can use MySQL replication capabilities to keep a copy of your database at database sites requiring high availability. See InnoDB and MySQL Replication.
