Penetration testers analyze and mitigate buffer overflow vulnerabilities to prevent exploitation by attackers.

Brute Force Attack

A Brute Force Attack is a method used by attackers to systematically try all possible combinations of passwords or encryption keys until the correct one is found. Brute force attacks are time-consuming but effective against weak or easily guessable credentials. Penetration testers may simulate brute force attacks to test the strength of authentication mechanisms and recommend improvements to prevent unauthorized access.

Man-in-the-Middle (MitM) Attack

A Man-in-the-Middle (MitM) Attack is a type of cyber attack where an attacker intercepts and modifies communication between two parties without their knowledge. MitM attacks can eavesdrop on sensitive information, manipulate data, or impersonate legitimate users. Penetration testers assess the risk of MitM attacks in web applications and recommend encryption protocols such as HTTPS to secure data in transit.

Denial of Service (DoS) Attack

A Denial of Service (DoS) Attack is a cyber attack that disrupts the normal operation of a web application by overwhelming it with a high volume of traffic or requests. DoS attacks can cause service outages, slow performance, or even crash the target system. Penetration testers evaluate the resilience of web applications to DoS attacks and recommend mitigation strategies to maintain availability under adverse conditions.
