Building an audit evidence pack for remote access

Why evidence packs matter more than policies alone

A policy document describes intent. An audit is interested in whether that intent was actually carried out, which means evidence has to demonstrate practice, not just describe it. For remote access, this distinction matters because the gap between a well-written policy and inconsistent day-to-day practice is common, and it is exactly the gap most audits are designed to find.

Building an evidence pack in advance, rather than assembling it reactively when an audit is announced, changes the character of the exercise. Instead of scrambling to reconstruct what happened over the past year, the organisation can simply hand over records that were being kept anyway as part of normal operation.

The policy and approval layer

The pack should start with the current remote access policy itself, showing who is authorised to grant access, under what circumstances, and what controls, such as named accounts and multi-factor authentication, are required. Alongside this, keep a record of individual access approvals: when a technician, supplier or member of staff was granted remote access, who authorised it, and what it covers.

This approval record does not need to be elaborate, a simple log with date, requester, approver, scope and justification is normally sufficient, but it needs to actually exist and be kept up to date as new access is granted, rather than reconstructed from memory when asked.

• Current, dated version of the remote access policy
• A log of individual access approvals with date, approver and justification
• Evidence that the policy is actually referenced when access is granted

The activity layer: session logs

This is usually the centrepiece of a remote access evidence pack: records showing who connected, to what, when, and for how long. Auditors will typically ask for a sample extract rather than the entire log, but that sample needs to be produced within a reasonable timeframe, which means the underlying logging and export capability has to work in practice, not just exist in theory.

It is worth periodically testing this yourself, well before an audit, by picking a date at random and confirming you can produce a complete, accurate log for it. Discovering during an actual audit that logs from six months ago were never retained, or cannot be exported in a usable format, is a preventable problem.

• Test log retrieval on a random past date before an audit, not during one
• Confirm the log export includes operator identity, target, and session timing
• Check that logs cover every remote access route, not just the main tool

The review layer: access reviews and exceptions

Granting access correctly at the outset is only half the story; auditors also expect to see that access is reviewed periodically, and that anything no longer needed is removed. A review record should show the date of the review, who conducted it, what was checked, and what changes, if any, resulted from it, such as accounts disabled or scope reduced.

Where exceptions exist, for example a piece of unattended access that does not fit the usual pattern, document the justification separately, since an unexplained exception is one of the things auditors are specifically trained to look for. A documented, reasoned exception is a far stronger position than an undocumented one, even if the underlying access is identical.

The retention and deletion layer

Finally, the pack should show that data is not simply accumulating indefinitely. If the organisation has a stated retention period for logs or recordings, keep evidence that deletion or anonymisation actually happens at the end of that period, such as a deletion log or a system configuration showing automatic purging.

Tools that produce structured, exportable session logs, such as 247connect, make this layer easier to assemble because the underlying records are already in a consistent, retrievable format rather than scattered across ad hoc notes or individual technicians' memories.
