Study Notes
User Account Control (UAC)
- User Account Control (UAC) is a security feature introduced in Windows Vista and included in Windows 7, designed to minimize risks from unauthorized actions or software installations.
- UAC prompts users for permission before making changes that could affect system security or performance.
Standard User Account
- A standard user account has minimal rights and privileges necessary for basic operations.
- Administrator accounts can perform any action on the system, including critical tasks that standard users cannot.
Customizing UAC
- To customize UAC settings, access User Accounts through the Control Panel; in Windows 7, it can also be adjusted via System and Security settings.
- For Windows Vista, UAC can be toggled in the Control Panel directly.
Consequences of Disabling UAC
- Disabling UAC or setting it to "Never notify" removes prompts for administrative changes, increasing vulnerability to security threats.
- Programs executed without UAC prompts gain the same level of access as the user, which can be risky.
Restart Requirement for UAC Changes
- Changes to UAC settings require a computer restart to take effect; however, some adjustments, like changing prompt behavior, do not need a restart.
Remote Desktop Overview
- Remote Desktop allows remote access to a computer; the server remains operational to accept connections.
- Host systems must be running Windows XP or higher, and Remote Desktop is available on specific versions (Professional, Business, Enterprise, Ultimate).
- Client machines need compatible software, which is included with Windows XP and later versions, while earlier versions require separate installation.
Remote Desktop Connection Features
- Users can redirect devices such as sound and printers from the client to the remote host, allowing seamless usage of local resources.
- Local drives can be mapped to the remote session for easier file transfers between the two machines.
Telnet Port Usage
- Telnet operates over TCP port 23, offering a plain-text, unsecured method for remote console connections.
SSH Port Usage
- Secure Shell (SSH) provides encrypted remote access, offering similar functionality to Telnet while maintaining data confidentiality.
Remote Assistance Port
- Remote Assistance connections require firewall configuration to allow traffic through port number 3389.
Application Management Insights
- Application installation involves more than file copying; it modifies system registry, creates shortcuts, and sets application-specific configurations.
- Shortcuts created during installation provide quick access to applications and can be set for individual or all-user access.
- Shortcuts that reference removable or network drives may become invalid if the drives are disconnected.
