Web API security

Web API security entails <a href="/facts/Authentication/64y4S69b">authenticating</a> programs or users who are invoking a <a href="/facts/Web_API/oVloUoIe">web API</a>.
Along with the ease of API integrations come the difficulties of ensuring proper <a href="/facts/Authentication/64y4S69b">authentication</a> (AuthN) and <a href="/facts/Authorization/FYFAkCH2">authorization</a> (AuthZ). In a multitenant environment, security controls based on proper AuthN and AuthZ can help ensure that API access is limited to those who need (and are entitled to) it. Appropriate AuthN schemes enable producers (APIs or services) to properly identify consumers (clients or calling programs), and to evaluate their access level (AuthZ). In other words, may a <a href="/facts/Consumer/dMflnQGX">consumer</a> invoke a particular method (business logic) based on the <a href="/facts/Credential/wsuEjr95">credentials</a> presented?
"Interface design flaws are widespread, from the world of <a href="/facts/Cryptography/e94PEVau">crypto</a> <a href="/facts/Central_processing_unit/Jxp1bqMV">processors</a> through sundry
<a href="/facts/Embedded_system/a4muX1wU">embedded systems</a> right through to <a href="/facts/Antivirus_software/GGMqsfkJ">antivirus software</a> and the operating system itself."
