Beratung zu IT-Sicherheit & Datenschutz


Die Datenschutz-Grundverordnung beziehungsweise das Bundesdatenschutzgesetz betreffen uns alle - jeder, der Daten von Dritten erfasst, speichert oder verarbeitet muss den europäischen Standard einhalten. Die umfangreichen Gesetzestexte regeln Rechte und Pflichten aber auch technische und organisatorische Maßnahmen zum Datenschutz, Aufbewahrungspflichten, Sicherheitsstandards und Vorgaben zur Dokumentation von Verfahren und Vorfällen sowie die Vorgaben zur Berufung eines Datenschutzbeauftragten mit einer besonderen Aufsichts- und Beratungspflicht.

Die DSGVO und das BDSG sollte dabei nicht nur schriftlich in langen Rechtstexten, Datenschutzhinweisen und Verfahrensdokumentationen umgesetzt werden sondern es sollten konkrete technische Standards etabliert und eingehalten werden um dem Verlust von Daten vorzubeugen, der unberechtigten Nutzung von Daten einhalt zu gebieten und Angreifer und Hacker zuverlässig abzuwehren.

Da umfangreiches Know-How sowohl im Bezug auf die Rechtsgrundlagen als auch auf die technischen Risiken und Möglichkeiten erforderlich sind um ein angemessenes Datenschutzkonzept zu etablieren haben viele Unternehmen große Schwierigkeiten bei der Umsetzung. Unsere IT- und Datenschutzberatung setzt hier an - mit unserer Expertise können wir Sie dabei unterstützen Datenschutz technisch und rechtlich angemessen umzusetzen.

Was steckt dahinter?

Das "Who is Who" - DSGVO, GDPR, BDSG, TMG, ...
Innerhalb der EU gilt seit 2018 die sogenannte General Data Protection Regulation (GDPR), die in Deutschland unter der Bezeichnung "Datenschutz-Grundverordnung" (DSGVO) in nationales Recht umgesetzt wurde. Das Bundesdatenschutzgesetz (BDSG) präzisiert die Regelungen der DSGVO und fügt weitere nationale Regelungen hinzu. Für Betreiber von Internetangeboten ist zudem das Telemediengesetzes (TMG) relevant. Dies bezieht sich allerdings weniger auf den Datenschutz als auf grundlegende Regelungen im IT-Recht.

Was ist Datenschutzberatung?
Unser TÜV geprüfter Datenschutzbeauftragter mit juristischer Qualifikation berät Sie gerne zu Fragen rund um die Umsetzung von Datenschutzrecht in Ihren konkreten Projekten. Darüber hinausgehende zivilrechtliche Fragestellungen hingegen fallen nicht in den Bereich der Datenschutzberatung.




Die rechtliche Seite: DSGVO

Die DSGVO beziehungsweise das Bundesdatenschutzgesetz stellen verschiedene Forderungen an Unternehmen und Organisationen die zwingend einzuhalten sind um rechtskonform Daten zu verarbeiten. Als Verarbeiter von Daten zählen Sie schon dann, wenn Sie die Daten von Mitarbeitenden oder Kunden erfassen oder speichern.

Damit gilt die DSGVO sowohl für Kleinstunternehmen und Vereine wie auch für große Unternehmen und global Player.

Während die gesetzlichen Regelungen in vielen Bereichen sehr präzise Vorgaben machen welche Dokumente und Verfahren es geben muss und welche Rechte, Pflichten und Fristen gelten, gibt es in vielen Bereichen auch große Unsicherheiten. Häufiger werden Maßnahmen gefordert die sich am Stand der Technik orientieren oder technische Notwendigkeit und Machbarkeit zur Maßgabe machen.

Im Rahmen einer rechtlichen Datenschutzberatung geht es darum Sie über Ihre Rechte und Pflichten als Datenverarbeiter zu informieren und gemeinsam zu prüfen und sicherzustellen, dass die geforderten Unterlagen und Prozesse korrekt umgesetzt werden. Wir zeigen Ihnen gernen auch Tools und Best Practices zur Umsetzung der Rechte Betroffener und Ihrer Pflichten als Verarbeiter.

Wir unterstützen Sie dabei den Überblick zu bewahren!

Die technische Seite: IT-Sicherheit

Während die rechtliche Seite sich viel mit Fragen nach Rechten und Pflichten, der Haftung und der Verantwortung beschäftigt, ist die technische Seite des Datenschutzes sehr viel präziser:

Wie verhindern Sie, dass Ihre Daten in falsche Hände kommen?

Sie sammeln und verarbeiten vermutlich jeden Tag Daten von Dritten und speichern diese in internen Tools, verarbeiten sie auf Ihren oder fremden Servern, übertragen Sie zu Dienstleistern oder bauen sogar einen wesentlichen Teil Ihrer Tätigkeit auf der Verarbeitung auf.

Ein potentieller Angreifer oder Hacker versucht stets den schwächsten Punkt zu identifizieren, um Zugriff zu Ihren Daten zu erlangen. Häufig nutzen Hacker dazu bekannte Sicherheitslücken nicht aktualisierter Systeme aus, suchen nach vergessenen oder auch versehentlich offen stehenden Türen oder greifen sensible Zugangsdaten ab, wodurch sie auch ohne große Anstrengungen unberechtigten Zugang erlangen und viel Schaden anrichten können. Dabei müssen Sie nichtmal das primäre Ziel des Angriffs sein, sondern könnten vermeintlich auch Opfer eines größer angelegten Angriffs auf mehrere Unternehmen werden.

Wir unterstützen Sie dabei, ein Sicherheitskonzept in Ihrer IT zu etablieren und die Angriffflächen zu reduzieren.





IT-Sicherheit - bleiben Sie auf dem Laufenden


Täglich werden neue Schwachstellen, Angriffs-Vektoren, Cyber-Attaken und Fehler in Software, Netzwerken und Infrastrukturen bekannt - teilweise betreffen diese nur bestimmte Softwarelösungen oder spezifische Szenarien, manchmal betreffen Sie jedoch auch ganze Industriezweige, weit verbreitete Arbeitsweisen und grundlegende Technologien wie bei Heartbleed (SSL) oder Log4Shell (Protokollierung). Ergreifen Sie Maßnahmen, um Ihre Infrastruktur und Daten sicher zu halten.

Gemeinsam erfassen wir, welche Komponten und Abhängigkeiten Sie einsetzen und überwachen die CVE und viele weitere Quellen um im Falle von Mängeln oder Angriffspunkten schnell handeln zu können.

Wir simulieren Angriffe und Testen Ihre Anwendungen, Webseiten, die Infrastruktur und Prozesse auf mögliche Sicherheitslücken, Mängel und Angriffsvektoren um Risiken fürhzeitig zu erknennen und Lücken zu schließen.

Wir implementieren aktiv Monitore und überwachen somit Anfragen um frühzeitig Angriffe und verdächtige Aktivitäten zu identifizieren. Verdächte Aktivitäten können zur Alarmierung oder zu automatischen Sperrungen und Ausschlüssen führen, um einen hohen Standard zu gewährleisten.


Den Bedrohungen der IT-Welt sind Sie nicht schutzlos ausgeliefert - es ist jedoch wichtig dem Thema IT-Sicherheit Aufmerksamkeit zu schenken, um einen verantwortungsbewussten und rechtskonformen Umgang mit Unternehmens- und Kundendaten zu gewährleisten.

Risiko ? / 10 CVE-2025-1889 gerade eben
picklescan before 0.0.22 only considers standard pickle file extensions in the scope for its vulnerability scan. An attacker could craft a malicious model that uses Pickle and include a malicious pickle file with a non-standard file extension. Because the malicious pickle file inclusion is not considered as part of the scope of picklescan, the file would pass security checks and appear to be safe, when it could instead prove to be problematic.

A vulnerability in the GraphCypherQAChain class of langchain-ai/langchain-community version 0.2.5 allows for SQL injection through prompt injection. This vulnerability can lead to unauthorized data manipulation, data exfiltration, denial of service (DoS) by deleting all data, breaches in multi-tenant security environments, and data integrity issues. Attackers can create, update, or delete nodes and relationships without proper authorization, extract sensitive data, disrupt services, access data across different tenants, and compromise the integrity of the database.
