The Uniscon company in Munich has sent us this timely and important warning note that – sure, our office is our home, is our kitchen, is our bedroom – but it is also the least secure of any aspect of our company data. In the same way as Wifi based home appliances are a gateway into our personal data – so our corporate laptop on the kitchen table is the same, into our company. They set out what you need to look for;
Digital transformation of the economy has opened up many new doors for cybercriminals. Companies must take appropriate measures to protect themselves and the data of their employees, customers and partners. But what do they need to consider?
Most of the provisions of the German Federal Data Protection Act (BDSG) and the General Data Protection Regulation (GDPR) boil down to a simple requirement: those responsible must guarantee the security of sensitive data. Violations can quickly become expensive: In the case of particularly serious data protection violations, the GDPR provides for fines of up to €20 million or up to 4% of the total annual turnover achieved worldwide (see Art. 83 GDPR). Following we present seven essential data protection measures for companies.
1. Compliance assessment
Compliance—this is, the observance of laws and regulatory requirements—affects all companies, but to different degrees. Depending on the industry, additional guidelines may apply in addition to GDPR and BDSG, for example, in the field of competition or financial law.
2. Risk assessment
As a next step, companies should carry out a risk assessment. After all, the more sensitive the data that is to be collected and/or processed, the more elaborated the measures to protect it must be. Assessments of this kind often require the support of a data protection officer.
It goes without saying that sensitive data must be encrypted both during transmission and storage. Sufficiently encrypted data is considered secure per se; even if data is lost, it cannot be read or recovered by attackers without the appropriate key.
All information that would help identify the user is removed. For example, the names of persons are replaced by randomly generated character strings. This way, the useful data remains but it no longer contains sensitive information.
5. Access controls
Introducing access controls into your company’s workflow is also an efficient method of minimizing the risk. The fewer people have access to the data, the lower the risk of accidental or deliberate data damage or loss.
Backups can help to prevent data loss due to user error or technical failure. They should be created and updated regularly. While regular backups add costs to your business, potential business disruptions are usually far more costly.
Under the GDPR, companies are obliged to delete the data that they do not need (see art. 5 and art. 17). Consequently, companies need to draw up an appropriate deletion concept. Depending on the type of data, this concept should also specify deletion periods and durations.
“Ultimately, companies must decide, whether they take appropriate measures themselves or use the services of third-party providers specializing in data protection and data security”, says Ulrich Ganz, Director Software Engineering at TÜV SÜD’s subsidiary uniscon. “Depending on the industry, the size of the company and the type of data collected and/or processed, this can save costs and simplify processes. For example, if companies use certified services, they can prove that they already fulfill their control and due diligence obligations as required by law”. This allows companies to concentrate on their core business—and leave data protection to the experts.
