Distributed Denial-of-Service (DDoS) Attacks
Man-in-the-Middle (MitM) attacks involve an attacker intercepting API communications to eavesdrop or manipulate data exchange. These attacks exploit unsecured channels, allowing attackers to intercept sensitive information such as login credentials and confidential data. APIs using weak or no encryption are particularly susceptible to MitM attacks, posing a substantial threat to data integrity and confidentiality.
Misconfigurations and poor API security practices are common reasons APIs become vulnerable in the cloud. Simple misconfigurations, such as exposing sensitive information in API responses or using weak authentication, can provide attackers with easy entry points. Additionally, APIs may be inadequately tested for security vulnerabilities, leading to overlooked flaws that attackers can exploit.
Man-in-the-Middle (MitM) Attacks
Authentication and authorization bypass attacks occur when attackers exploit API weaknesses to gain unauthorized access to systems. Improperly implemented authentication protocols or missing authorization checks are common vulnerabilities exploited in such attacks. This allows attackers to impersonate legitimate users or access sensitive data without appropriate permissions, posing significant security risks.
API attacks can compromise the entire cloud infrastructure, leading to unauthorized access and control. Attackers exploiting weak APIs gain entry points to manipulate underlying cloud frameworks. This compromise can result in the alteration of infrastructure configurations, resource abuse, and unauthorized provisioning of services. Such actions can disrupt system integrity, leading to further vulnerabilities and decreased trust in cloud solutions.
API Abuse and Misuse
API gateways and web application firewalls (WAFs) play crucial roles in shielding APIs from attacks. API gateways manage and mediate communication while providing a single point of access control, handling tasks like authentication, rate limiting, and traffic routing.
