Antivirus (AV) :

💠 Focus: Detects and removes known malware (e.g., viruses, worms, Trojans).

💠 Method: Relies on signature-based detection for identifying threats.

💠 Purpose: Baseline protection against common malware.

💠 Scope: Blocks known threats but struggles with advanced, unknown attacks.

Endpoint Detection and Response (EDR) :

💠 Focus: Monitors and mitigates advanced threats on endpoints.

💠 Method: Uses behavioral analysis, threat hunting, and real-time monitoring.

💠 Purpose: Provides deeper visibility and control to handle unknown and targeted attacks.

💠 Scope: Responds to suspicious activities on individual devices.

Extended Detection and Response (XDR) :

💠 Focus: Delivers cross-platform, holistic threat detection and response.

💠 Method: Integrates data from multiple tools (e.g., AV, EDR) for better threat correlation.

💠 Purpose: Comprehensive security by connecting insights across different layers.

💠 Scope: Broad coverage across networks and endpoints, enhancing protection against complex attacks.

HOW TO INSTALL LINUX ON AN OLD COMPUTER

HOW TO INSTALL LINUX ON AN OLD COMPUTER

To install Linux on an old computer, you need to download a Linux distribution (like Ubuntu or Linux Mint), create a bootable USB drive using a tool like Rufus, boot your computer from the USB, and follow the on-screen instructions to install Linux on your desired partition, choosing a lightweight distribution that is optimized for older hardware if necessary; remember to back up any important data before proceeding as the installation process may overwrite existing files on your hard drive.

Key steps:

1. Choose a Linux distribution: Select a lightweight Linux distribution designed for older hardware, like Xubuntu, Lubuntu, or Debian.

2. Download the ISO image: Go to the chosen Linux distribution's website and download the latest ISO file.

3. Create a bootable USB drive: 1) Use a tool like Rufus or UNetbootin to write the ISO image to a USB drive. 2) Ensure your USB drive is formatted properly.

4. Boot from USB: 1) Insert the USB drive into your old computer. 2) Access your BIOS settings by pressing the appropriate key during startup (usually F2 or Del). 3) Change the boot order to prioritize the USB drive.

5. Start the installation process: 1) When the computer boots from the USB, you will be presented with a live Linux environment. 2) Select your language and keyboard layout. 3) Choose "Install Now" and follow the on-screen instructions.

6. Partition your hard drive: 1) Decide if you want to install Linux alongside your existing operating system (dual boot) or completely replace it. 2) Allocate sufficient disk space for your Linux installation.

7. Complete the installation: 1) Set your username, password, and other preferences. 2) The installer will format the selected partition and install Linux.

Important considerations:

• Backup your data: Before installing Linux, ensure you have backed up any important files from your old computer.

• Check hardware compatibility: While most modern Linux distributions work well with older hardware, check if your specific components are fully supported.

• Adjust settings for performance: Once installed, you may need to tweak settings like the desktop environment to optimize performance on older hardware.
