CIDR allows for the allocation of IP addresses in variable-length prefixes, enabling more flexible and scalable addressing. CIDR notation represents IP addresses in the format "address/prefix length," where the prefix length specifies the number of bits in the network portion of the address.
Application Security:
Application security refers to the measures taken to protect software applications from security threats and vulnerabilities. This includes ensuring that applications are developed using secure coding practices, implementing authentication and authorization mechanisms, and regularly updating and patching applications to address known vulnerabilities. Application security is essential for protecting sensitive data and preventing unauthorized access to applications.
