Security saved on disk
Previous entries discussed the principles of maintaining security when using smartphones and creating passwords. Another important aspect of digital security of your organization is a back up. Establish a backup policy and policy first. When creating them, it is worth taking into account data retention, planned recovery time, type of backup (incremental, total), data type, backup mechanisms (online and offline) and its speed as well as the planned medium.
In order for the backup to be effective, it is necessary to create backups regularly, in the recommended 3-2-1 model, which means that important files should be stored in 3 copies, on at least 2 different media, 1 of which should be off-site.
Unfortunately, the latest data do not fill us with optimism, especially in the face of the growing wave of ransomware attacks (involving disk encryption and extortion, usually paid in cryptocurrencies) and the constantly growing amount of ransom payments. In Poland, only 24% of respondents declare that they perform backups regularly and 26% never do it! Among the remaining respondents, 33% do it ad hoc, another 17% perceive its importance only after an undesirable event. The statistical research was carried out by the SW Research studio on a sample of over 1000 companies in March 2021.
