Any experience relating to information security would be advantageous, but not essential. All topics discussed are thoroughly explained and presented in a way allowing the information to be absorbed by everyone, regardless of experience within the security field.


We have DLP or data loss prevention systems. Now, this is a cybersecurity solution that encompasses installations on a variety of platforms that seeks to detect and prevent data breaches. Typically, they will block the extraction of sensitive data and organizations use it for internal security and regulatory compliance purposes, as well as data and privacy protections. It allows the businesses to identify the sensitive information resources across multiple premises, whether they are on-prem or cloud-based. They help in prevention of accidental data sharing. They monitor and protect data directly. And part of how we have to do this is to educate users on how to stay compliant.

Now, encrypted exfiltrated data is sometimes employed by hackers to prevent pattern recognition and outbound data streams and this tends to be a feature of most ransomware. Another form of data protection is digital rights management, sometimes referred to as IRM or information rights management. Most of what this is used for is to protection of intellectual property, to be in conjunction with laws that can be effective deterrence, but these alone cannot prevent infringement and theft. DRM provides many different features, including copy protection and features about timing, geography, uses and others, and they provide usage rights and are intended to ensure authenticity and integrity as well. These will ensure enforce security for files and properties that must be shared with a widely separated audience, and yet for the sake of their owners or the copyright holders, still ensure proper access control and constraints on usage outside of their wishes.
