Data retention of employees records, security and privacy

1. Introduction

I’d like (with support of human resources) to build an Awareness session + Document related to the current “data retention of employees records, security and privacy” in my company.

This subject is touchy and can hurt people is only technical aspect is presented to the audience.

2. Content

The document may contains,

  • Introduction, situation, goal.
  • The inventory and
  • The different measures related.
  • The risks and
  • The benefits, for employees and company.

The presentation may be a summary of situation, goals, the risk/benefits and their implications. +Q&A

1) Situation

Draw the current situation, and clearly explain that recording of events is not new. It’s a normal day to day process required in different systems and applications.

Giving some examples.

2) Goals

Make them aware that some records are available and can be used (with certain conditions) to :

2.1. 1. Protect the company.

  • It can be used in case of legal or security investigation (internal and external).
  • It will permit to solve and/or detect breach or incident rapidly.
  • It will permit to easily make better diagnostic
  • It It will permit to respect some proportionality in case of investigation (employees are aware).

2.2. 2. Protect the employees – This is really important –

  • No confusion. It clearly explains them we don’t want to hide some security tools that can hurt their sensibility. Company and management have codes of conduct.
  • It will permit employees to protect themselves in case of abuse (harassment (mail, …), accusation) .

I defined the points to clarify, because many question will pops-up. Some are generic, some need pin-point solution.

1) Confidentiality

  • Access to logs – Who has access to logs – Who can request access to events.
  • What is done records ? Reports, statistics, screening, nothing.
  • What will prevent abuse ?
  • Is there notification in case of investigation ?
  • 4 eyes controls ?

2) Integrity

  • What will guaranty integrity
  • What will prevent fraud
  • 4 eyes controls ?
  • What is the procedure in case of forensic ? Copy, export, …
  • Is it possible, to erase records on demand ? (For privacy or legal reason)

3) Availability

  • When logs are recorded ? All day long, 24/24, Business Days, After hours …
  • Duration/Retention – how long records are available and kept (one week, one month, archived forever)
