There are a number of Resource Record (RR) types defined in RFC 1035 and augmented by subsequent RFCs. The $TTL directive should be present and appear before the first RR (RFC 2308 implemented in BIND 9). The first Resource Record must be the SOA (Start of Authority) record. The generic format is described below.
Many RRs share a common format. Each DNS Server contains RRs for the portion of the name space for which it is authoritative. The DNS WMI Provider currently supports the following RR types. Click the name of the resource record to jump to its reference page.
A DNS resource record (RR) contains all the information about a domain name system. It defines all the attributes for a domain name such as an IP address or a mail route. Name.
This field is necessary because a DNS name can have more than one type of RR. Class. This defines the protocol family for the RR record. For example, IN, which stands for Internet. Time To Live (TTL).
DNS resource records are contents of the DNS zone file. The zone file contains mappings between domain names and IP addresses in the form of text records. There are many types of the resource records. In this article, we are going to see DNS Resource Records in detail.
SOA Record. Every zone file will have a SOA record. It will be present at the beginning of the zone. The SOA stands for Start of Authority. Normally, this type of record holds information about the zone itself and about other records. Each zone will be having only one SOA record.
The NS record stands for nameserver record . This shows the authoritative servers the zone. They indicate primary and secondary servers for the zone specified in the SOA record. Zones can contain many NS records, but it should contain at least one NS record for a DNS zone.
After completing the information gathering and assessment of gaps by departments, the records manager needs to analyze and research the listings of all records categories. Each department determines how long the records are needed for business purposes, while the records manager conducts legal research to determine all laws and regulations that pertain to the particular record series or category. The final step is to reconcile the legal requirements against the business requirements for each record and marshal the results towards a simplified records retention schedule that is easier to use and less expensive to maintain over time. Because of the over 14,000 laws that have recordkeeping requirements, records managers often outsource this piece to consultants or law firms that specialize in this detailed research.
Regularly-timed reviews of the records retention schedule and policy for relevancy will also ensure that the schedule and program remain viable. The records manager works with each department periodically to systematically review the schedule for additions or replacements of record categories, as well as removal of obsolete categories. Legal research should be conducted regularly to update record keeping requirements. The records manager also conducts periodic inspections of offices to ensure the company’s policy regarding records retention and disposition is being followed consistently and thoroughly. This inspection includes a written review of findings from shared network drives and collaborative workspaces, document management repositories, e-mail accounts, desk drawers, file cabinets and application systems. Records management leadership and company culture impact whether these reviews are received as a threat, or a planning and information management exercise.
Records retention is a vital part of your records management program . However, there is more to records and information management (RIM) than just keeping your records for a specified number of years and then disposing of them. Setting up a comprehensive RIM program typically requires the following actions:
The first step in creating a records retention schedule is to determine which records each department or business unit maintains. A combination of survey, interview and/or inventory methods can be used. The amount of detail required in the process will depend on the structure of the schedule. A department-specific schedule or a condensed “functional” schedule may be utilized by your organization. Industry standards recommend a “functional’ schedule with more broadly defined records categories. Records retention can be managed at a higher level and inherited to the file level. A file plan can then be created to provide additional filing guidance. A condensed functional schedule reduces administrative costs and the risks associated with inconsistency. For example, within a detailed schedule vendor contracts are a separate category from purchasing agreements; whereas in a functional schedule, these examples of contracts and agreements are treated equally and require no further detail.
Company records include information assets that contain the collective knowledge of the company. Clear procedures secure and protect those assets. Deliberate implementation strategy: After creating a records and information management policy it is critical to define efficient operational methods and effective risk mitigation strategies as you move forward with implementation. The cost of waiting to develop a records retention program can ruin a company’s financial health. The sooner you start, the sooner you will gain peace of mind with a program that is compliant, consistent and cost effective.
How do we achieve compliance while meeting business objectives in an era of shrinking budgets, often compounded by overloaded resources and increasing cyber threats ? This is the question on every senior manager’s mind. As the regulatory landscape becomes increasingly complex, corporations continue their expansion into the global marketplace, and data analytic opportunities also expand. Records retention and destruction is often a low priority for organizations until is it too late. Should costly litigation or disaster strike, managers quickly find out if their current mechanisms are solid or inadequate.
