Study Notes
Digital vs Manual Files
- Digital files consist of typed information, while manual files are handwritten
- Manual files are always in hard copy form, stored in different places, whereas digital files are stored in soft copy in a digital location (computer, hard disk, etc.)
- Digital files can be easily transferred through email and other electronic forms, whereas manual files are difficult to transfer and more time-consuming
Benefits of Digital Files
- Time-saving in editing, changing, and transferring files
- Better efficiency in record keeping
- Easier to set up paper trails when needed for businesses
- Use of templates removes repetition in file keeping
- No more paper and filing costs, with less filing cabinets needed for storage
- Files can be accessed quickly and at any time
Limitations of Digital Files
- Risks of file insecurity, losing, overriding, or corrupting information
- Security breaches are a concern
- New users to technology may be skeptical about the authenticity and validity of digital documents
File Insecurity
- Concept that all files have vulnerabilities and can be lost or missing in the computer
- File security is a feature that controls who can access which files and limits what users can do to various files
- Effects of file insecurity include losing, overriding, or corrupting information, and unauthorized access to files
Securing a File
- Keep computer and devices updated
- Use strong passwords
- Use anti-virus software
- Encrypt hard drive and mobile device
- Restrict access to others (non-editing permissions, etc.)
Five Pillars of Cybersecurity
- Confidentiality: ensuring information is not disclosed to the wrong individuals
- Integrity: ensuring information is not damaged or modified during transmission
- Availability: maintaining access to information and services
- Non-repudiation: proving the identities of the sender and recipient
- Authentication: confirming identities before allowing access to cyber services
Digital Security Strategies
- Implementing the five pillars of cybersecurity through digital and physical strategies
- Password entropy: measuring the complexity and unpredictability of passwords
- Encryption: encoding messages to hide their true meaning
- Decryption: converting encrypted messages back to plaintext
Encryption and Decryption
- Encryption: process of changing plaintext to ciphertext for security
- Decryption: process of converting ciphertext back to plaintext
- Symmetric key encryption: using one key for both encryption and decryption
- Public key encryption: using different keys for encryption and decryption
Physical Cybersecurity Strategies
- Ensuring physical security of devices, servers, and data centers
- Using biometric authentication (facial recognition, finger or eye scans) for improved authenticity
- Understanding that connected devices can be entry points for attackers
