Study Notes
Cybersecurity Awareness
- Cybersecurity encompasses technologies, processes, and practices safeguarding networks, computers, programs, and data from unauthorized access, damage, or attacks.
- In computing, "security" often refers to cybersecurity.
- Protecting personal information, devices, and networks is crucial due to malicious intent.
- Attacks can occur both online and through social engineering.
Personal Data
- Offline Identity: Your identity in everyday life (home, school, work).
- Online Identity: Your identity in cyberspace, requiring limited information disclosure.
- Username or Alias: Should not reveal personal information, be appropriate and respectful, and avoid attracting unwanted attention.
Hacker Motivation
- Financial Gain: Profiting from stolen information.
- Reputation Damage: Tarnishing an organization’s reputation.
- Activism and Political Revenge: Using cyberattacks to achieve political goals or seek retribution.
- Pride and Challenges: Hacking for recognition or a sense of accomplishment.
- Fun or Because They Can: Hacking for amusement or out of curiosity.
The Value of Personal Data
- Personal information, email addresses, financial details, passwords, and account information are valuable on the dark web.
- Computers can be exploited for cryptocurrency mining.
- Hackers can profit from selling large collections of stolen information.
Types of Personal Data
- Medical Records: Electronic Health Records (EHR), prescriptions, and other personal health information.
- Education Records: Grades, test scores, courses taken, awards, degrees, attendance records, and disciplinary reports.
- Employment and Financial Records: Income, expenditures, tax records (paycheck stubs, credit card statements, credit rating, banking statements), and past employment information.
Data Locations
- Medical Records: Doctor’s offices and insurance companies.
- Store Loyalty Cards: Stores collect purchase data, used by marketing partners for targeted advertising.
- Online Pictures: Friends and strangers may have copies of your photos.
Computing Devices
- Data storage and gateways to online data.
Low-Effort Attacks
- Often target thousands of users simultaneously, using tactics like phishing emails, fake social media giveaways, and malicious websites.
- Such attacks aim for a high volume of attempts, hoping someone will fall victim.
Ransomware
- Typically installed through downloads, attachments, or links in emails or websites.
- Locks the screen or encrypts data, demanding a ransom for access.
- The Wannacry attack (2017) affected 300,000 computers across 150 countries, including organizations like the NHS, Renault, FedEx, and German railways.
Tackling Ransomware
- Back Up Data: Create and maintain a backup copy of data, disconnected from the network.
- Patch Software: Update software regularly to prevent known vulnerabilities (like those exploited by Wannacry).
- Caution With Attachments: Avoid clicking on links from emails or SMS messages from untrusted sources.
Phishing
- Attempts to deceive users into revealing sensitive information like login credentials, payment card details, or installing malware.
- Often impersonates legitimate companies or individuals.
Tackling Phishing
- Don’t Click on Links: Verify the sender before clicking on any links in an email.
- Trusted Contact Methods: Use alternative methods like phone numbers, apps, or official websites to contact companies.
- Mark as Spam: Report suspicious emails as spam.
Secure Website Indicators
- Correct Website: Ensure you are on the intended website.
- HTTPS and Padlock: The "S" in HTTPS indicates a secure connection, preventing man-in-the-middle attacks. This encrypts data, making it unreadable to unauthorized parties.
