It’s always wise to remember good practices related to the registration and administration of domain names, especially when referring to portfolios with tens or hundreds of them. Good practices allow companies to have their online operations uninterrupted and prevent them from losing their domain names due to expiration or hijacking. It is noteworthy that poor practices can lead to disruptions in business, loss of customer confidence and harm to reputation, among other negative consequences.
Three good practices are:
Keep Registration Information Up to Date
At the point of creation of each domain name, the registrant provides contact details to the registrar. This information is then made publicly available via the WHOIS service, allowing companies to be contacted for a wide number of reasons – including technical or operational matters associated with the domain, interest in the content posted on the associated website, or security concerns.
Individuals/Companies should make sure that the contact data as displayed in WHOIS is accurate and up-to-date. Incorrect or obsolete information can prevent security researchers from contacting registrants whose domains may have been compromised, or potential business partners from establishing a contact that could lead to a new business opportunity.
Don’t Use Personal Email Addresses
Companies should not use personal email addresses in the registration data of their corporate domain names. This recommendation includes both email addresses that employees use outside of work and email addresses that identify individuals in the organization. Both can leave a company vulnerable.
● Don’t allow the members of staff who will register the domains to use their personal email addresses, such as email@example.com or firstname.lastname@example.org. The email addresses listed for the registrant and the administrative contact of a domain name are key for its administration. When employees’ personal email addresses are listed, nothing prevents them from hijacking the domain when they leave the company.
Providing the names of individuals involved in the administration of corporate domain names exposes them to an increased risk of social engineering and spear-phishing attacks aimed at the company. Instead, use role-based or department-based names, ideally with several users receiving communications sent to those addresses.
Avoid Having Domain Names In-Bailiwick
Attackers who gain control of a domain name in the bailiwick can redirect email by replacing the legitimate name servers with name servers that they operate. They can then add an MX record that directs email to a mail server that they also operate. Or they can turn off email entirely by deleting the domain’s MX record, in which case no email will be sent to or received by the company that registered the affected domain.
An extra layer of difficulty is added when the registrar cannot communicate with the affected company, as it has no access to its corporate email. This situation requires out-of-band communication and proof to the registrar that the company is indeed the affected registrant.
