Security metrics are measurements that are used to evaluate and improve the effectiveness and efficiency of security processes, controls, and outcomes. The best characteristics of security metrics are that they are consistently measured and quantitatively expressed, as this ensures that the metrics are objective, reliable, comparable, and verifiable. Security metrics should not be generalized or provide a broad overview, as this may reduce their accuracy, relevance, and usefulness. Security metrics should not use acronyms and abbreviations to be concise, as this may cause confusion, ambiguity, or misunderstanding. Security metrics may use bar charts and Venn diagrams, or other graphical or visual representations, to illustrate or communicate the results, but this is not a characteristic of the metrics themselves, but rather a presentation technique.

A salted cryptographic hash of the password is a control that protects the confidentiality of the credential while it is stored in a relational database. A salt is a random value that is added to the password before hashing it, to make it more resistant to brute-force attacks and rainbow tables. A hash is a one-way function that transforms the password into a fixed-length output that is difficult to reverse. A salted hash makes it harder for an attacker to guess or crack the password, even if they have access to the database.

IEEE 802.1X is a standard for port-based Network Access Control (PNAC). It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN, preventing unauthorized devices from gaining network access.

According to the CISSP Official (ISC)2 Practice Tests, reciprocal backup site agreements are considered to be easy to implement for similar types of organizations. A backup site is a location or a facility that is used to restore the business operations and functions, as well as the supporting resources, such as data, systems, personnel, and facilities, in the event of a disaster that disrupts the normal operations of an organization. A backup site can be classified into different types or levels, based on the availability, functionality, and compatibility of the backup site, such as the hot site, the warm site, or the cold site. A reciprocal backup site agreement is a type of backup site agreement that is established between two or more organizations that have similar types or levels of backup sites, and that agree to provide or share their backup sites with each other in the event of a disaster that affects one or more of the organizations. A reciprocal backup site agreement is considered to be easy to implement for similar types of organizations, as it does not require a lot of resources, costs, or efforts to set up or maintain the backup site agreement, and as it provides a high level of compatibility and flexibility for the backup site agreement.

Updating the contract so that the vendor is obligated to provide security capabilities is the best approach to address the issue of software security not being addressed in the draft contract.
Software security is the aspect of information security that deals with ensuring the confidentiality, integrity, and availability of the software applications and services, and preventing or mitigating the software vulnerabilities, flaws, or defects that may compromise the security of the software or the data processed by the software. Software security is an important and essential requirement for any software development project, especially for a healthcare insurance organization that handles sensitive and personal information of the customers and the patients. Updating the contract so that the vendor is obligated to provide security capabilities means that the vendor has to comply with the security requirements and standards that are specified by the organization, and that the vendor has to demonstrate and prove the security of the software that they develop, deliver, or maintain. Updating the contract so that the vendor is obligated to provide security capabilities can help to ensure that the software security is addressed and integrated throughout the software development life cycle, and that the software security is aligned with the organization's security objectives and policies.
