Study Notes

Security Attacks and Threats

Denial of Service (DOS) and Distributed Denial of Service (DDOS) attacks can incapacitate servers.
File Transfer Protocol (FTP) may facilitate anonymous uploads of illegal software.
Firewalls filter traffic between trusted and untrusted zones in a Local Area Network (LAN) and Wide Area Network (WAN).
Open ports on firewalls increase vulnerability to external access.

Network Domains

The LAN domain comprises sub-networks with servers and clients managed by a centralized database.
The WAN domain spans extensive geographic areas, either private for business connections or public for network interconnectivity.
Remote Access Domain allows flexible access to system resources, enhancing collaboration and productivity across global teams.

User Types in Windows

Local users’ credentials are stored locally on the computer, allowing access only to that machine.
Domain users’ credentials are managed by a domain controller, facilitating access across multiple computers within a network.

Remote Access Technologies

IPsec VPN provides a secure remote access solution but requires a client installation on users’ machines, which may complicate access.
SSL VPN enables easier client installation from public portals, with less direct IT intervention.

Software and Server Vulnerabilities

Software vulnerabilities may arise in any application, including common ones like Adobe Flash or custom in-house software.
Server vulnerabilities present heightened risks due to potential access to critical services and operating systems.

Data Loss and Prevention

Data loss can occur during storage, transmission, or processing, making it a significant concern in the system/application domain.
Regular data backups and off-site storage are essential for data recovery and risk mitigation.

Risk Reduction Strategies

Employ physical security for sensitive areas and implement encryption standards to protect data.
Limit access to data, maintaining an awareness of all network applications.
Promote ethical standards and professional conduct among colleagues to safeguard the profession's reputation.
