protokollamanipulaatiota

Protokollamanipulaatiota, known in English as protocol manipulation, refers to a class of cybersecurity attacks that exploit vulnerabilities in the way network protocols are designed or implemented. These attacks involve intercepting, altering, or fabricating network traffic to achieve malicious outcomes. The core idea is to trick systems into believing that the manipulated data is legitimate, leading to unauthorized access, data theft, or disruption of services.

Common techniques within protocol manipulation include spoofing, where an attacker impersonates a trusted entity by forging the source address in a network packet. Session hijacking is another method, where an attacker takes over an established communication session between two parties. This can be achieved by stealing session tokens or by predicting session IDs.

Other forms of protocol manipulation involve exploiting weaknesses in the protocol's state machine or its handling of error conditions. For instance, an attacker might send malformed packets that cause a server to enter an unstable state or reveal sensitive information. The widespread use of various network protocols, from basic ones like TCP and UDP to more complex application-layer protocols, provides a broad attack surface for these types of threats. Defending against protocol manipulation often requires a combination of robust protocol design, secure implementation, network intrusion detection systems, and proper network configuration.
