    Study Notes

    How Anti-Virus (AV) Works

    • AV takes multiple steps to lower the risk of malware, including signature-based diagnostic, heuristic testing, sandboxing, behavior blocking, firewall, blacklisting, and trust systems.
    • Signature-Based Diagnostic: Tests files and website certifications against a database of known threats.
    • Heuristic Testing: Checks code for malicious patterns, assigning a score to determine if it's malicious.
    • Sandboxing: Runs code in a safe, isolated environment to inspect untrusted code and prevent threats from accessing the network.
    • Behavior Blocking: Analyzes program behavior to proactively protect against known and unknown threats.
    • Firewall: Filters internet traffic before it enters the network or computer, applying rules to determine safe traffic.
    • Blacklisting: Prevents execution of undesirable programs, including those known to contain security threats or vulnerabilities.
    • Trust Systems (Whitelisting): Checks applications against other users and the main AV database to determine trustworthiness.

    Pre-Installed Solutions in Major Operating Systems

    • Windows: Windows Defender, Microsoft Security Essentials
    • Mac: XProtect
    • Linux: chkrootkit (can be downloaded as one of many options)

    Shortcomings of AV Solutions

    • Signature-Based Diagnostic: Can be cheated by malware developers using crypting services, making malware Fully Undetectable (FUD).
    • Heuristic Testing: Can impact machine speed, restrict application use, and lead to whitelist approach or blacklisting issues.
    • Privacy Concerns: Trust system approach can lead to privacy loss, as AV software may send user data to main servers.

    Finding the Best AV Solution

    Shortcomings of AV Testing

    • Most testing is funded by AV software companies, raising questions about trustworthiness of results.

    Next-Generation AVs

    • Next-generation AVs (NG-AV) are using machine learning and Artificial Intelligence (AI) to detect and remove malware and malicious software.
