What is Digital Security?
Digital security is a broad discipline that encompasses a range of practices, tools and strategies for safeguarding digital identities, data and systems against unauthorized access, attacks and disclosure. It also protects against damage or destruction of those assets. Cybersecurity is a critical factor in the modern world as it helps organisations protect against the ever-evolving threats that can have catastrophic consequences, such as the recent Marriott breach that exposed personal information to over 500 million people.
The main aspects of digital security are availability, authentication and authorisation, integrity, and accountability. Availability ensures that systems, networks and data are available when needed. This includes strategies like load balancing, redundancy and business continuity planning. Authentication verifies the identity of users or devices and ensures that only those who are authorised can access protected resources. Authorisation enforces the principle of least privilege, granting only those permissions necessary to do their work. Integrity ensures that data remains accurate and complete throughout its life cycle using techniques such as checksums, hashing, digital signatures and version control systems. Accountability involves logging and tracking activities to identify suspicious or unauthorised activity.
As a result of the increasing dependence on computers and technology, hackers are becoming more sophisticated and frequent in their attacks. A single security breach can lead to significant financial losses and damage a brand’s reputation as well as the trust of its audience. As a result, it’s more important than ever to make sure that your organisation is using the best methods and processes for digital security.
