Cyber Attacks and Tape Storage
It has become common to hear news about cyber-attacks, such as unauthorized accesses targeting
financial institutions. Damages from fraudulent financial transactions perpetrated through attacks
from phishing sites have increased significantly since last year. Recently, attacks targeting IoT
devices have also begun to increase. Furthermore, since the beginning of this year, there seem to
have been a series of attacks taking advantage of the situation caused by COVID19 virus and crimes
It is said that "defense in depth" is necessary for the threat of cyber-attacks that are becoming
more diverse and sophisticated. Defense in depth is a method of taking multi-layered countermeasures
against cyber-attacks in multiple areas, such as "entrance" measures that do not allow unauthorized
access or malware intrusion, and "internal" measures that minimize damage when intrusion is allowed.
This is achieved by combining "exit" measures that prevent information from being taken out.
As one of the "internal" measures, using tape for backup is highly effective for encryption by
ransom ware and data tampering. Since the tape media can be removed and stored offline, the
physically separated "air gap" protects the data from unauthorized encryption and tampering. When
data on the online system is tampered with or otherwise damaged, the original data can be quickly
restored from a backup copy that is secured in a safe location. As cyber-attack methods evolve day
by day, it is difficult to prevent all intrusions 100%, and it is especially important to be able to
recover data even if an intrusion occurs.
Some people may be concerned about the tape being physically stolen from storage, however, the tape
drive that writes data to the tape media has a strong encryption function, so using this can prevent
information being leaked even if the tape is stolen.
It is said that remote working will remain as the new normal, even after the COVID-19 virus has
subsided. With all the possible different ways of working remotely, the boundaries between internal
and external networks are blurring. So, companies need to be prepared for various risks coming from
outside. In the future, we believe that tape storage will be one of the most effective means of
preparing for these new threats.
