What influence does the hardware have on IT security?

NSA warnt vor Wildcard-Zertifikaten und Alpaca-Angriffen

Cyber attacks on companies are continuously increasing and cause tens of billions of dollars of damage every year. It is no longer just large companies and multinational corporations that are targets of hackers and other cybercriminals, but SMEs are also increasingly exposed to attacks. In particular, the increased work in the home office in the course of the corona pandemic has led to the fact that attacks on corporate networks have increased significantly in the past two years.

In order to protect themselves from corresponding dangers and to prevent further security problems, most companies rely exclusively on software-based solutions. However, security software alone no longer provides sufficient protection against data theft or other threats. In order to ensure the best possible security for the entire IT infrastructure, the hardware must above all be protected.

Lack of software protection is hardly an issue today

Most companies use software to reliably protect themselves against cyber threats. Appropriate solutions are no longer a major cost factor and can reliably detect and neutralize numerous threats. As a rule, there are tariffs for both small and large companies that optimally cover the individual requirements and needs of companies. Daily updates ensure that new threats can also be detected reliably and immediately.

However, as soon as criminals carry out targeted attacks on the hardware, even the most reliable software protection is useless. In this regard, there are several attack surfaces. Therefore, IT hardware and software must be effectively protected.

Corporate computers / servers as a gateway

A simple example of how software-based security solutions can be circumvented is, for example, playing data on a company computer to an external data carrier. In this way, employees or even external persons who gain access to corresponding devices could steal potentially sensitive data in a simple way. In exactly the same way, a malicious code or other malicious program can also be injected into the company network using a USB stick. The strict control and assignment of access rights at different levels is therefore a basic prerequisite for a secure infrastructure, which also includes the careful configuration of cloud services . It may also be useful to store computers and servers in lockable cabinets to prevent unauthorized third-party access.

Another important aspect in this context is the prevention of data loss . Many companies still do not secure their systems against failure or neglect to regularly back up all relevant company data with backups. In addition to external hard drives that automatically perform such data backups at regular intervals, so-called RAID systems may also be available. These consist of two or more physical drives and ensure maximum reliability of the system. As soon as one drive should crash, another one immediately jumps in and thus ensures proper operation.

Conclusion

In connection with the fourth industrial revolution, Industry 4.0, the requirements for IT security are becoming increasingly higher. Companies that do not pay enough attention to the protection of their IT infrastructure take a big risk. While until a few years ago it was completely sufficient to use professional software solutions to protect against threats, today the best possible IT security can only be achieved by a combination of software and hardware protection.
