The organization is implementing homomorphic encryption. Homomorphic encryption is a type of encryption that allows computations to be performed on encrypted data without decrypting it first. This means that the organization can analyze the customers’ data and deliver analysis results without being able to see the raw data, preserving the privacy and confidentiality of the customers. Homomorphic encryption can enable various applications, such as cloud computing, machine learning, and data analytics, that require processing sensitive data without compromising security.

An ISA, or interconnection security agreement, is a document that should be required to set up a dedicated VPN between two entities that provide specialized help desk services. An ISA defines the technical and security requirements for establishing, operating, and maintaining a secure connection between two or more organizations. An ISA also specifies the roles and responsibilities of each party, the security controls and policies to be implemented, the data types and classifications to be exchanged, and the incident response procedures to be followed.

The most likely cause of the signature failing is that the certificate is set for the wrong key usage. Key usage is an extension of a certificate that defines the purpose and functionality of the public key contained in the certificate. Key usage can include digital signature, key encipherment, dataencipherment, certificate signing, and others. If the certificate is set for a different key usage than digital signature, it will not be able to sign the applications properly. The administrator should check the key usage extension of the certificate and make sure it matches the intended purpose. Verified References:

A risk associated with SDN is the expanded attack surface that it introduces. SDN is a network architecture that decouples the control plane from the data plane, allowing centralized and programmable management of network devices and traffic. However, this also exposes new attack vectors and vulnerabilities that can compromise the security and performance of the network. For example, an attacker can target the SDN controller, which is the core component that communicates with and controls the network devices. A successful attack on the SDN controller can result in denial of service, unauthorized access, data leakage, or network hijacking. An attacker can also exploit the communication channels between the SDN controller and the network devices, such as the OpenFlow protocol, to intercept, modify, or inject malicious messages or commands. Additionally, an attacker can leverage malicious or compromised applications that run on top of the SDN controller to manipulate or disrupt the network behavior. Verified References:
