Computer Security Day – bewahren Sie Ihre Online-Daten sicher auf


On 30 November, we celebrate National Computer Security Day. It is a special day that reminds us how important it is to keep our online data safe and raises awareness of computer security issues. 

Today, smartphones, tablets, and computers have become essential to our everyday lives. The various ways in which we make use of these devices make them so powerful. They let us communicate faster than ever before; they make it easier to get things done; they enhance our productivity. The benefits come at a cost – modern technology has brought new concerns about privacy and security.

It is not a surprise then that our society has recognized the importance of computers’ safety and has dedicated a special day to commemorate computer security – November 30 is National Computer Security Day.

History of the National Computer SecuritDDay

Geschichte des Tages der Computersicherheit

Cyber security is a top priority all over the world. And on National Computer Security Day, people are reminded to stay updated with their cyber protection measures to keep themselves safe from any online attacks or breaches of privacy.

The story of National Computer Security Day starts in November 1988. Researchers from Cornell University discovered an unknown virus attacking their computer systems, which they named the “Morris worm”. Soon the virus invaded several other universities with interconnected computing systems via the ARPANET network (the predecessor of today’s Internet). Several days later, a Computer Emergency Response Team (CERT) was assembled – to respond 24/7, 365 days per year, to any attacks that harm the university computing systems nationwide.

Ende November stand das Datum bereits fest: der 30. November. 

This date was chosen on purpose, as the authorities wanted to draw attention to computer safety, especially during the festive season when many people are focused on their shopping lists for the coming holidays and seem to ignore security threats. Three decades later, we also have a National Cybersecurity Awareness Month dedicated to encouraging people to be proactive regarding their online security. After all, our digital life should be protected and secure, just like real life. 

Warum brauchen wir den Tag der Computersicherheit mehr denn je?

Hacking, viruses, and malware attacks have been major threats to consumers and businesses since the early days of modern computers. Yet, as technology becomes more complex and ubiquitous in our digital universe, the potential for hackers to exploit any vulnerabilities grows.

Mit mehr gefährdeten Daten (zum Teil, weil elektronische Geräte immer stärker in unser Leben integriert werden) aus Banktransaktionen und Verwaltungsdiensten etc., wird die Ressourcenzuweisung zu einem viel komplizierteren Prozess als je zuvor. Robuste Sicherheitssysteme, die die verschiedenen zu beschützenden Arten von Daten berücksichtigen, ob persönlich oder beruflich, können einen großen Beitrag zur Sicherung unseres künftigen digitalen Universums leisten.

Der CSD ist ein wichtiger Tag im Kalender, weil:

• On this day, you should remember that your privacy remains a precious asset and cannot be entrusted only to programmers. You play an active role in computer security by ensuring regular up-to-date antivirus software is installed on all devices used for personal or professional use. Also, strong passwords should be used for each account with sensitive information. Stored data has to be securely encrypted so it is not easily accessible through hackers’ news feeds.

• It highlights that our computer and mobile security problems also concern others. We live in a society where we all are interconnected via sophisticated computer systems. Аs viruses spread fast, it is important to protect not only your devices but other computers as well. An infected device can cause enormous damage to an entire private or corporate network.

It is the perfect opportunity to show our appreciation for the unsung heroes of our digital era – the security system engineers. Their task is always to be one step ahead of the cyber hackers to protect our network and online privacy from possible intrusion. That requires long hours of learning to update their professional skills and knowledge constantly. Also, to mastermind the modern technologies and design solutions that help us live a secure online life.

Den Tag der Computersicherheit richtig feiern

1. Erstellen Sie ein starkes Passwort
starkes Passwort

In 2021 having a strong password is a golden standard for securing your computers, mobile devices, and data stored in the cloud safe and protected. Do not forget to update it regularly to ensure your data or business information is protected from breaches. Some useful tips when creating a trustworthy password include:

• Erstellen Sie ein Passwort, das nicht leicht zu hacken ist – 9 Zeichen ist hierfür die perfekte Länge
• Nutzen Sie für Ihr Passwort einen Mix aus Klein- und Großbuchstaben, Symbolen und Zahlen
• Benutzen Sie auf keinen Fall für jedes Konto das gleiche Passwort
• Aktualisieren Sie Ihr Passwort regelmäßig

2. Update your antivirus program and malware protection software 

Updating the protection software of your operating system is vital, but many users ignore it. Every few months, you should scan your personal and office devices – mobile ones included – for spyware or other malware that can infect your computer network and endanger your data. Make sure you have installed the latest versions of the protection software programs.

3. Verschlüsseln und sichern Sie Ihre Daten

Why should you encrypt your data? Encryption keeps hackers from accessing your information when using a public network, such as at the library or the free WiFi in your coffee shop. 

Protecting sensitive information and data is much easier than rebuilding an entire business from scratch. The best way to do it is to use encryption software, which turns files into codes that can only be deciphered using a password or key. That ensures that anyone who hasn’t been granted access cannot access your information. However, creating an additional backup for all your important files is always a good idea. Data backup solutions like Dropbox and Google Drive can store information and share files.

Despite National Computer Security Day being just one day of the year, you should always pay attention to your online safety.

National Computer Security Day is a way to honor those who work tirelessly to keep your data safe. It is also an excellent time to think about how to protect your online security. Applying simple steps like creating strong passwords, updating antivirus programs, and encrypting your information, can be a game-changer. We all live in a digital universe that consists of interconnected devices. They build the infrastructure allowing us to communicate, collaborate, operate, and inform ourselves about the surrounding world. But with many benefits to enjoy, you should not underestimate cyber threats. Educate yourself constantly on how you can proactively protect yourself.

Und vergessen Sie nicht – jeder Tag sollte für Sie ein Tag der Computersicherheit sein!
