Study Notes

Strong Passwords

Strong passwords are difficult to crack or guess.
Should include at least one capital letter.
Should include at least one numerical value.
Should include at least one other keyboard character (such as @, *, &).

Firewalls

Act as a barrier between your device and the internet.
Can be software or hardware-based.
Monitor and filter information going in and out of your device.
Allow users to approve or deny communication from external sources.
Tasks:
- Examine traffic between devices and public networks.
- Block traffic that doesn't match specific criteria.
- Log all incoming and outgoing traffic for future analysis.
- Prevent access to harmful IP addresses.
- Help protect against viruses and hackers.
- Warn users if any software tries connecting to external data sources.

Antivirus Software

Continuously monitors for virus attacks in the background.
Common functions:
- Checking software/files prior to execution.
- Comparison with known virus database.
- Heuristic checking for suspicious behavior.
- Quarantine suspect files; allowing automatic removal or manual review.
Requires regular updates due to constant discovery of new viruses.
Weekly full system scans are recommended to detect dormant viruses.

Encryption

Alters readable data (plaintext) into an unreadable format (ciphertext).
Uses a mathematical process with an encryption algorithm and a key.
The key and process are complex enough to make brute force attack extremely unlikely.
Decryption reverses the process using the same key or a different decryption key.
Offers no protection against file deletion.
Safeguards data integrity and confidentiality.

Biometrics

Uses the unique characteristics of human beings to enhance security.
Examples include fingerprint scans, retina scans, face recognition, and voice recognition.

Hacking

Unauthorized access to a system with the intent to cause harm.
Types:
- Malicious: Aims at stealing sensitive information, modifying files.
- Ethical: Authorized testing, evaluating cyber security strength, legal, commissioned by organizations.

Malware

Small programs that pose a threat to data integrity and security.
Types:
- Viruses: Self-replicate, delete or corrupt files, need active host programs.
- Worms: Standalone viruses seeking other vulnerable computers via networks.
- Logic Bombs: Embedded codes triggered under specific conditions.
- Trojans: Harmful programs disguised as legitimate software.
- Bots: Automated scripts vulnerable to unauthorized takeover and attacks.
- Spyware: Monitors keystrokes, sends gathered information to a sender (keylogging).

Phishing

Emails that look legitimate but contain links or attachments that lead to fake websites or trick users into revealing personal information.
How to prevent:
- Be vigilant for new scams.
- Avoid clicking unconfirmed links and unknown file downloads.
- Be cautious of offers that are too good to be true.
- Utilize anti-phishing toolbars on web browsers for warnings.
- Periodically examine digital accounts and modify passwords routinely.

Two-Factor Authentication (2FA)

Requires two forms of authentication for account login.
Uses username/password combo with a second authentication factor like a phone number, fingerprint, or security code.
Often involves a one-time code (OTP) sent to a mobile device or email address.
Confirms account ownership before granting access.

Internet Ethics

Acknowledge and accept cultural differences online.
Refuse to participate in online abuse and harassment.
Keep spam to a minimum.
Share content that is meaningful.
Respect others' privacy.
Be cautious about sharing personal information online.
