Study Notes
Risks to Data and Personal Information
- Criminals may try to access and use personal or financial information to commit fraud or identity theft.
- Data is transmitted and stored digitally, creating an increased risk in the digital world.
Unauthorized Access
- Unauthorized access to networks can occur directly or through software by hackers attempting to gain access.
- Botnets are groups of computers controlled for malicious purposes, such as running and spreading malware.
Malware
- Malware can damage systems by displaying messages, playing sounds, deleting files or even reprogramming systems to perform malicious tasks.
- Ransomware threatens to delete files or restrict access to software and resources until a payment is made.
Accidental Deletion
- Users can accidentally delete files or even entire drives due to accidental key presses, incorrect formatting, or unexpected power loss.
Theft of Personal Data
- Phishing is a technique where criminals send messages, often disguised as legitimate organizations, to trick users into providing their personal and financial information.
- Spear phishing targets specific users with highly customized messages.
- Pharming manipulates websites to mimic real ones and trick users into entering their login information.
- Criminals achieve this by redirecting internet traffic to their fake websites or using malware to alter web traffic routing.
- They often create similar URLs to the real website to mislead users who may misspell the address.
Methods to Secure Data and Personal Information Online
- Firewalls control data flow in and out of a network, using rules to determine which traffic is allowed.
- Encryption scrambles data into an unreadable form, making it unusable without the decryption key.
- Passwords, PINs, and biometrics are used for user authentication. Strong passwords are recommended, including:
- Length greater than 8 characters
- Random characters (not common words, names, or dates)
- Mix of letters, numbers, and symbols
- Frequent changes
- Unique passwords not used for other accounts.
- CAPTCHA tests help distinguish human users from automated software (bots) by requiring users to enter displayed letters or numbers, which bots cannot read.
- Anti-spyware software helps detect, quarantine, and remove spyware that may be trying to steal personal data.
- Access rights and file permissions limit access to files, folders, and drives, preventing unauthorized access.
- Secure websites use HTTPS (Hypertext Transfer Protocol Secure) to authenticate payment servers and provide encryption, ensuring secure connections.
- Users should be cautious when opening email attachments or hyperlinks, as they may contain malware designed to steal personal information. Pay special attention if:
- The sender is unknown
- The message is generic, impersonal, or irrelevant
- The message has spelling or grammatical errors
- The attachment is an executable file (e.g., .exe or .zip)
- The message urges immediate action
- The URL is unfamiliar.
- Backup procedures create copies of data, stored on external storage devices or online.
- This safeguards data in case of device failure, damage, loss, or theft.
- Consider backing up data regularly to ensure the latest versions are protected.
- Use online storage for additional safety, keeping data in multiple locations.
Online Payment Systems
- Various payment systems allow online transactions for goods and services, transmitting payment details across networks.
Online Third-Party Payment Processors
- Services like PayPal and Skrill allow users to send and receive money using email accounts for identification.
- They integrate with online shopping applications for smoother transactions.
Bank Cards
- Bank cards enable online and in-store payments. Users need the following information:
- Card number
- Expiry date (and sometimes start date)
- Cardholder's name
- Card Security Code (CSC)
- Secure systems require password authentication for online payments.
- Mastercard Secure Code is an example of such a system.
Contactless Cards using NFC
- Near Field Communication (NFC) enables contactless payments, eliminating the need for PINs or user authentication.
