One backup is often not enough

A backup alone is often not enough, because data is threatened from many sides. Regardless of whether it is the information of a private individual or a company, it is and remains valuable - and not just for the people concerned. The security software manufacturer ESET therefore provides tips on how to protect data from loss and theft.

Tips for data protection

In addition to up-to-date security software that can remotely lock or delete information, an encryption solution is a good place to start. But beware: while encryption can fix a lot of backup problems these days, it's not a panacea.

1. Individual encryption: In addition to regular backups, you can create double security by using encryption methods tailored to your individual needs. It is important to secure the digital copies as well - and not with the same system. Encryption according to the Advanced Encryption Standard (AES) with a key length of at least 192 bits (AES-192) is considered secure. If possible, however, the use of AES-256 is recommended.
2. Secure storage and transmission: When it comes to data protection, it is critical to distinguish between so-called data at rest ("data in rest") and information in motion ("data in motion"). The former is data that is not publicly accessible, for example, data that resides on the hard drive of a computer that is turned off. The latter is data that can be accessed during transmission or that has been sent. Both types of data can be protected from external access by encryption.
3. A question of trust: There are a number of commercially available encryption programs, some at reasonable, others at horrendous prices. In any case, install a certified solution with standard encryption algorithms and a sophisticated key procedure for secure data exchange among users.
4. Increased protection through strong passwords: Encryption can minimize risks, but not eliminate them entirely. Other protection mechanisms, such as strong passwords used exclusively for securing data, create additional security. In general, the security of a password increases with the degree of complexity. For example, special characters, upper and lower case letters, and an illogical string of individual digits ensure that the password cannot be guessed and is difficult to crack.
