What is an Attack Vector?
An attack vector refers to the method or pathway through which a cybercriminal can gain access to a computer or network in order to deliver a malicious payload or exploit a vulnerability. In the realm of web application security, attack vectors are particularly important because they highlight potential weaknesses that can be exploited by attackers aiming to compromise sensitive data, disrupt services, or manipulate web applications for malicious purposes.
Common attack vectors in web application security include:
- Cross-Site Scripting (XSS): This occurs when an attacker injects malicious scripts into web pages viewed by users, potentially leading to data theft or session hijacking.
- SQL Injection: This vector allows attackers to execute arbitrary SQL code, which can manipulate, read, or delete data from a database.
- Cross-Site Request Forgery (CSRF): This technique tricks users into executing unwanted actions on a web application where they are authenticated, exploiting trust relationships.
- Remote File Inclusion: An attacker includes a file from a remote server, potentially leading to execution of malicious code.
Understanding these vectors helps organizations enhance their security posture through stronger coding practices, regular security audits, and implementing appropriate security measures such as firewalls and intrusion detection systems.
