Secure communication: How companies protect their data from attacks

The protection of business interests is one of the highest goods for companies. It is important to prevent data from being unlawfully stolen from the company – be it through hacker attacks or espionage. In addition to internal requirements to protect information, customers, suppliers and partners of a company also have a legitimate interest in protecting their data.

In addition, companies must comply with legal obligations, such as the requirements of the General Data Protection Regulation, the IT Security Act, the Federal Data Protection Act or the Act on the Protection of Business Secrets.

The IT Security Act 2.0

What has changed with the updated version in the past year? What obligations apply to companies with a special public interest and operators of critical infrastructures (CRITIS)?

You can read more about this in our blog post.

Ultimately, however, you should weigh up the risks for your specific case on your own responsibility. In addition to a possible liability risk, a hacker attack can also result in an economic risk. The damage to your image that can result from data loss should not be underestimated.

Important to know

Data must be encrypted at all storage locations. This includes servers, workstations (desktop and laptop) and other mobile devices. This also applies to external areas, i.e. branch offices, data centres and field service devices.

Safeguarding business interests through (email) encryption

Hans-J. Giegerich, Managing Director at GP InfoCon, spoke about this topic at “Digital instead of analogue”, BAYOOSOFT’s series of events:

Companies are also victims of cyber attacks on a regular basis. In this lecture, you will learn how you can protect your business interests in the best possible way, not only with the help of email encryption, but also with the help of the Internet.

How can you adequately protect your data in corporate communications?

Encrypt your data to protect it during communication, both internally and externally. There are two ways to do this. You can encrypt data during transport or the content itself.

Encrypt the transport
Security during the transport of data is supported by TLS (Transport Layer Security). One disadvantage, however, is that the data usually only remains encrypted during transport, i.e. between the transmission from mail server to mail server.
Encrypt the content
If you communicate data via e-mail, it is precisely this that should be protected. This way, the data remains encrypted between the exchange from user to user – i.e. during the entire process instead of only during transport.

On the end device itself, information is encrypted and is only decrypted at the destination user.

One option for email encryption via Outlook is the software solution gpg4o.

How does secure email encryption work with gpg4o?

gpg4o uses an asymmetric encryption method for email encryption. This system uses key pairs consisting of a private, i.e. secret, key and a public key. The recipient’s public key is used to encrypt the e-mail.

This can then only be decrypted again with the private key of the recipient. You can find more information on this in the explanatory videos and the IT glossary.
