S/MIME (Secure/Multipurpose Internet Mail Extensions) is a protocol that provides security services for email messages, such as encryption, digital signature, authentication, and integrity. S/MIME is based on the MIME standard, which defines the format and structure of email messages. S/MIME uses public-key cryptography to encrypt and decrypt the message content and to sign and verify the message sender. S/MIME supports various algorithms for encryption and digital signature, such as Diffie-Hellman, DSS, RSA, and triple DES. S/MIME is widely used for secure email communication in various applications and platforms, such as Outlook, Gmail, and Thunderbird. S/MIME is the protocol that employs the features mentioned in the question, namely Diffie-Hellman (X9.42) with DSS for digital signature and triple DES for encryption. Reference:

Containerization is a practice that helps security professionals protect mobile applications from various attacks. Containerization is a technique that isolates critical corporate data from the rest of the device data and applications. Containerization creates a secure and encrypted environment on the device where the corporate data and applications can be accessed and managed. This way, containerization prevents unauthorized access, data leakage, malware infection, or device theft from compromising the corporate data and applications12.

The correct sequence of steps involved in the creation of a data retention policy is 3 -> 1 -> 4 -> 5 -> 2. This is based on the following description of the data retention policy creation process from the web search results:

Build a team: To design a data retention policy, you need a team of industry experts, such as legal, IT, compliance, and business representatives, who can contribute their knowledge and perspectives to the policy. The team should have a clear leader who can coordinate the tasks and communicate the goals and expectations1.

Determine legal requirements: The team should research and understand the applicable legal and regulatory requirements for data retention that affect the organization, such as GDPR, HIPAA, PCI DSS, etc. The team should also consider any contractual obligations or industry standards that may influence the data retention policy2134.

Identify and classify the data: The team should inventory and categorize all the data that the organization collects, stores, and processes, based on their function, subject, or type. The team should also assess the value, risk, and sensitivity of each data category, and determine the appropriate retention period, format, and location for each data category2134.

Develop the data retention policy: The team should draft the data retention policy document that outlines the purpose, scope, roles, responsibilities, procedures, and exceptions of the data retention policy. The policy should be clear, concise, and consistent, and should reflect the legal and business requirements of the organization. The policy should also include a data retention schedule that specifies the retention period and disposition method for each data category2134.

Ensure that all employees understand the organization's data retention policy: The team should communicate and distribute the data retention policy to all the relevant employees and stakeholders, and provide training and guidance on how to comply with the policy. The team should also monitor and enforce the policy, and review and update the policy regularly to reflect any changes in the legal or business environment2134.
