    Cyber warfare refers to engaging in war with the help of the internet and cyber methods. It does not require physical presence to use cyber warfare as a weapon. Its ability to transcend boundaries has made it possible for cyber warfare to be used as a tool for geopolitical influence. Here are some of the important points to elucidate:

    • Surveillance– Cyber attackers steal classified data used for surveillance to attack a country’s infrastructures, such as transport, healthcare, or defense.
    • Sabotaging military networks- A country’s defense and military networks are usually connected with each other via satellites. If these networks are sabotaged then these throws the national security of that country into a disorder. This is usually done by one country to other to undermine their defenses.
    • Spreading of misinformation- Controlling and spreading of misinformation to influence public opinion is one of the ways in which cyber warfare helps in changing the geopolitical scenarios.
    • Lack of Evidence- Cyber attacks usually do not leave back any evidence which makes it harder for it to trace, thus making the work of perpetrator easy.

    Main Techniques in Network Intrusion Detection Systems (NIDS)

    1. Signature-Based Detection: Matches network traffic against a database of known threat signatures (patterns of known attacks).
    2. Anomaly-Based Detection: Establishes a baseline of normal network behavior and detects deviations from this norm.
    3. Heuristic-Based Detection: Uses algorithms and rules to identify suspicious activity based on behavior patterns.
    4. Hybrid Detection: Combines signature-based and anomaly-based methods to enhance detection capabilities.

    Signature-Based Detection

    How It Works:

    • Compares incoming network traffic to a predefined database of known attack signatures.
    • If a match is found, it triggers an alert.

    Advantages:

    • High accuracy for known threats.
    • Low false-positive rate when signatures are up to date.

    Limitations:

    • Ineffective against unknown or zero-day attacks.
    • Requires regular updates to the signature database.

    Anomaly-Based Detection

    How It Works:

    • Establishes a baseline of normal network behavior through statistical analysis or machine learning.
    • Monitors network traffic for deviations from this baseline, flagging anomalies as potential threats.

    Advantages:

    • Can detect novel or previously unknown attacks.
    • Adaptive to changes in network behavior over time.

    Limitations:

    • Higher false-positive rate due to normal network changes being flagged as anomalies.
    • Requires significant time and resources to establish and maintain an accurate baseline.

    Summary

    Signature-based detection is precise for known threats but lacks effectiveness against new attacks. Anomaly-based detection excels in identifying unknown threats but can generate more false positives. Combining both methods in a hybrid approach can leverage the strengths of each, providing a more robust NIDS solution.
