Description: Firewall evasion refers to the techniques used to bypass the protections offered by firewalls, devices or software designed to control network traffic and protect computer systems from unauthorized access. These techniques can include packet manipulation, the use of proxies, data fragmentation, and protocol modification, among other methods. Firewall evasion is a critical aspect of cybersecurity, as attackers constantly seek ways to bypass security barriers to access vulnerable networks and systems. On the other hand, network administrators must be aware of these techniques to implement more effective security measures and maintain the integrity of their systems. The relevance of firewall evasion lies in its ability to compromise an organization’s security, which can result in data loss, service interruptions, and damage to reputation. In an environment where cyber threats are becoming increasingly sophisticated, understanding and mitigating evasion techniques becomes a priority for any cybersecurity strategy.
