Study Notes

Internet Privacy

Internet privacy concerns individuals' rights to control their displayed, stored, and confidential information online.
Internet privacy is crucial for controlling personal information; without it, malicious individuals can exploit identities for theft.

Different Techniques to Protect Internet Privacy

Securing Web Browser
- Google Chrome and Mozilla Firefox are popular web browsers known for their features, but they do not guarantee total security. It's advisable to check reviews, explore security features, and compare usability before making a choice.
Using a Virtual Private Network (VPN)
- A VPN is the best method for Internet privacy, as it changes the IP address and encrypts traffic, keeping online activities and personal information secure.
Double-checking Unfamiliar Links
- Never trust links from suspicious sources like emails, websites, or advertisements. Always verify the URL format before clicking, as phishing sites often disguise themselves as trusted brands, posing significant risks.
Limited Sharing on Social Media
- Social media platforms like Instagram, Facebook, and Twitter are publicly accessible. Users can enhance privacy by locking accounts or making them private, and should limit personal posts to protect against threats.
Using Multi-factor Authentication
- Multi-factor authentication adds an extra verification step to passwords. For example, Google requires a code sent to users' smartphones, reducing the risk of cyber threats.

Network Security

Network security ensures the integrity, confidentiality, and accessibility of networks, especially as cybercriminals exploit vulnerabilities, necessitating enhanced precautions.

Network Technologies

Firewall
- A firewall monitors and filters network traffic, acting as a barrier between trusted internal and untrusted external networks by allowing only verified traffic based on set rules.
Intrusion Detection System (IDS)
- A network intrusion detection system (IDS) monitors for malicious activity using a signature-based detection method that identifies patterns of known threats and employs machine learning to create a model of normal activity for comparison. A host intrusion detection system (HIDS) operates on individual hosts, monitoring traffic flow and taking file system snapshots to detect unauthorized modifications, alerting administrators of any changes in critical files.
Wi-Fi Protected Access 3 (WPA3)
- WPA3, the latest wireless network security protocol by the WiFi Alliance, filters new device connections at entry and provides "forward secrecy," ensuring past encrypted sessions remain secure even if the server's private key is compromised.
Virtual Private Network (VPN)
- A VPN connects remote devices to an enterprise server, ensuring users' online activities are hidden while accessing company data over a public network.
Email Security
- Emails can embed scripts, making it easy for malicious codes to be attached and sent. To combat this, effective security methods include deep learning spam filters to block spam domains.

Consequences of Internet and Network Failure

Revenue Loss
- One of the most significant consequences of internet and network downtime for companies is revenue loss, even if brief. Proper cable management and regular internet monitoring can enhance network reliability.
Maintenance Cost
- Repairing damaged internet and network lines incurs time and costs for new cables and devices. Daily monitoring is essential to prevent downtime..
Lesser Productivity
- Internet and network failures greatly reduce productivity, as employees are halted until issues are resolved. To mitigate this, organizations should implement backup networks and internet service providers.
Damaged Reputation
- Frequent internet and network failures harm employees, clients, and partners, suggesting negligence in management. A robust maintenance system is recommended to prevent issues and assure security for all users.
Legal Repercussions
- Failures in operations can result in missed outputs and legal consequences. To prevent this, it's essential to notify all relevant parties immediately to devise recovery plans while maintaining quality and client demands.
