The Email Retention Policy is intended to help employees determine what information sent or received by email should be retained and for how long.
The information covered in these guidelines includes, but is not limited to, information that is either stored or shared via electronic mail or instant messaging technologies.
All employees should familiarize themselves with the email retention topic areas that follow this introduction.
Questions about the proper classification of a specific piece of information should be addressed to your manager. Questions about these guidelines should be addressed to the Infosec Team.
This email retention policy is secondary to the eCuras policy on Freedom of Information and Business Record Keeping. Any email that contains information in the scope of the Business Record-Keeping policy should be treated in that manner. All eCuras email information is categorized into four main classifications with retention guidelines:
4.1 Administrative Correspondence
eCuras Administrative Correspondence includes, though is not limited to, clarification of established company policy, including holidays, time card information, dress code, workplace behavior, and any legal issues such as intellectual property violations. All email with the information sensitivity label Management Only shall be treated as Administrative Correspondence. To ensure Administrative Correspondence is retained, a mailbox admin@eCuras has been created; if you copy (cc) this address when you send an email, retention will be administered by the IT Department.
4.2 Fiscal Correspondence
eCuras Fiscal Correspondence is all information related to revenue and expense for the company. To ensure Fiscal Correspondence is retained, a mailbox fiscal@eCuras has been created; if you copy (cc) this address when you send an email, retention will be administered by the IT Department.
4.3 General Correspondence
eCuras General Correspondence covers information related to customer interaction and the business’s operational decisions. The individual employee is responsible for email retention of General Correspondence.
4.4 Ephemeral Correspondence
eCuras Ephemeral Correspondence is by far the largest category and includes personal email, requests for recommendations or review, email related to product development, updates, and status reports.
4.5 Instant Messenger Correspondence
eCuras Instant Messenger General Correspondence may be saved with the logging function of Instant Messenger or copied into a file and saved. Instant Messenger conversations that are Administrative or Fiscal in nature should be copied into an email message and sent to the appropriate email retention address. The Jabber Secure IM Client is the only IM approved for use on eCuras computers.
4.6 Encrypted Communications
eCuras encrypted communications should be stored in a manner consistent with eCuras Information Sensitivity Policy, but in general, the information should be stored in a decrypted format.
4.7 Recovering Deleted Email via Backup Media
eCuras maintains backup tapes from the email server, and once a quarter, a set of tapes is taken out of the rotation, and they are moved offsite. No effort will be made to remove email from the offsite backup tapes.
4.8 General Standards
Approved Electronic Mail
Includes all mail systems supported by the IT Support Team. These include, but are not necessarily limited to Mailchimp. If you have a business need to use other mailers, contact the appropriate support organization.
Approved Encrypted email and files
Techniques include the use of DES and PGP. DES encryption is available via many different public domain packages on all platforms. PGP use within eCuras is done via a license. Please contact the appropriate support organization if you require a license.
Approved Instant Messenger
The Jabber Secure IM Client is the only IM approved for use on eCuras computers.
Individual Access Controls
Individual Access Controls electronically protect files from being accessed by people other than those specifically designated by the owner. This is accomplished on UNIX machines by careful use of the chmod command (use man chmod to find out more about it). On Mac’s and PC’s, this includes using passwords on screensavers, such as Disklock.
Insecure Internet Links
Insecure Internet Links are all network links that originate from a locale or travel over lines that are not totally under the control of eCuras.
Secure eCuras Sensitive information in accordance with the Acceptable Encryption Policy. International issues regarding encryption are complex. Follow corporate guidelines on export controls on cryptography, and consult your manager and/or corporate legal services for further guidance.
5.1 Compliance Measurement
The Infosec team will verify compliance with this policy through various methods, including but not limited to periodic walk-thrus, video monitoring, business tool reports, internal and external audits, and feedback to the policy owner.
The Infosec team must approve any exception to the policy in advance.
An employee found to have violated this policy may be subject to disciplinary action, up to and including termination of employment.
