Study Notes

Communication Security

Communication always carries the risk of transmitting sensitive information.
Risks arise from both technical vulnerabilities and human errors.
Sharing sensitive information can have serious personal and professional consequences.
A heightened sensitivity to handling confidential information is essential to safeguard against human errors.
Even seemingly trivial information can pose security risks, especially if used to deceive others.

Information Classification

Clearly labeling information confidentiality is vital for proper handling.
Classification categories define protection measures, access rights, and security checks required for information.
German authorities classify information into categories such as:
- VS-NfD (for official use only)
- VS-Confidential
- Secret
- Top Secret

Non-disclosure Agreements (NDA)

NDAs are binding agreements that mandate confidentiality regarding specific information.
Breaches often come with stipulated penalties and liability issues.
NDAs are commonly included in employment contracts to facilitate sharing confidential information.
Confidential information must be clearly defined within the NDA.

Data Exchange

Sharing sensitive information imposes specific demands on communication technologies.
Common methods for sharing information include emails, cloud file sharing, and instant messaging.
Various measures are needed to ensure confidentiality across all communication channels.

Email Attachment Security

Incoming email attachments may contain malware; never open suspicious attachments.
Scan attachments for viruses and use a secure environment to open them if necessary.
Always check the file type and extension; executable files may be disguised as other formats.
Treat warnings from your system seriously, particularly with office documents or text files.
Confirm the sender's identity if attachments are unsolicited.

Outgoing Email Considerations

Outgoing email attachments can unintentionally share internal data, such as unnecessary information.
Creating 'closed' files, particularly PDFs, is recommended unless a different approach is warranted.
File sharing options provide greater control than email attachments.

Many organizations use cloud services for storing and sharing files.
Utilize password protection for sharing links and set expiration dates to limit link validity.
Remove files and shares once they are no longer needed.
Give direct permissions to users with accounts rather than using general sharing links.

Instant Messaging Security

Messaging platforms support real-time chat and file transfers, necessitating end-to-end encryption.
Apps like Threema and WhatsApp offer end-to-end encryption for messages and files.
Ensure HTTPS configurations for self-hosted chat services like RocketChat or Mattermost.

Understanding Spam

Spam refers to unsolicited emails sent to a large number of recipients, often containing advertisements, phishing attempts, or malware.
Spam filters analyze content and technical characteristics to identify spam:
- Content features include keywords and known text patterns.
- Technical features involve mail server reputation and IP address checks.
Spam filters calculate a likelihood score of emails being spam.

Phishing Awareness

Phishing involves urging recipients to disclose credentials or sensitive information through impersonated login forms.
Such attempts often appear legitimate, directing victims to fake login pages.
General phishing targets a wide audience, while spear-phishing uses specific details to target individuals.
Always access websites directly by typing URLs rather than following email links.

Social engineering involves manipulation techniques to coerce individuals into specific actions.
Deception and false identities are commonly employed.
Scrutinize requests for information carefully and verify the identity of the requester.
In case of uncertainty, consult responsible parties within your organization.

Scamming Techniques

Scamming entails elaborate deceptions aimed at extracting personal information or money from victims.
Often initiated through job platforms or social networks, scamming involves continuous, personal interaction to build trust.
The collected data may lead to further exploitation, such as extortion.

Identity Theft

Identity theft involves using someone else's identity to create a plausible appearance.
Scammers often register email addresses and social media profiles using stolen or public information.
Information garnered through public resources or social engineering enhances identity theft opportunities.
