Security Basics: Checking Vendor Access Logs Before You Need Them
Most security conversations focus on prevention: strong passwords, multi-factor sign-in, and careful permission settings. Those matter, but they answer only half the question. The other half is whether you can see what happened after a login succeeded. Access logs, the records a system keeps of sign-ins, permission changes, exports, and administrative actions, are the evidence you rely on when something looks wrong. For small businesses and technical readers who juggle many software tools, the practical question is not whether logs exist in the abstract but whether you know where to find them, who can read them, and what they actually contain. This article walks through a simple method for reviewing access records across your tools without assuming any particular vendor offers a specific feature set.
Start With an Inventory of Where Access Happens
Before you can review logs, you need a list of the places where people sign in or where data can leave your control. Start with a plain spreadsheet. List every tool that stores company information, every shared account, every admin console, and every service that connects to others through tokens or integrations. Include the tools people adopted on their own, since those are the ones most likely to be missing from official records.
For each entry, record four things: the owner or responsible person, the type of data it holds, who currently has access, and how sign-in works. Note whether it uses individual accounts, a shared login, or a single-sign-on arrangement tied to another system. The goal is not perfection on the first pass. The goal is to notice gaps, such as a shared mailbox that three people use with one password, or an integration that still has access from a former contractor.
Learn What a Useful Access Record Contains
A record is only useful if it answers basic questions: who did something, what they did, when it happened, and from where. When you review a tool, check whether its activity history shows sign-in events, failed attempts, role or permission changes, data exports, and the creation or deletion of accounts and API keys. Each of these events tells a different part of the story. A burst of failed sign-ins followed by a successful one points to a different problem than a single export of a large customer list.
Pay attention to what is missing as well. Some tools keep detailed activity for a short window and then discard it. Others record administrative actions but not read-only views. Do not assume that because a log exists, it covers everything you care about. Write down what each tool records, what it omits, and how far back the history goes.
Ask Vendors the Questions Their Documentation Might Skip
Product pages and help centers often describe what a tool does but not how long it keeps activity records, who can read them, or whether you can export them for your own review. Send these questions directly, and keep the answers in writing so you can refer back to them. Useful questions include: How long is activity history retained? Can administrators filter events by user, action, and date range? Can records be exported in a format your team can review? Who at the vendor can access your activity data, and under what circumstances? What happens to records when an account is deleted?
Be cautious of vague answers. A response such as 'we take security seriously' does not tell you anything about retention or visibility. If an answer is unclear, ask for the specific policy document or the setting where the behavior is configured, and verify it yourself rather than relying on a summary.
Build a Simple Monthly Review Routine
Logs only help if someone looks at them. For a small team, a monthly review of the most important tools is realistic and effective. Choose the three to five systems that hold the most sensitive data or have the most administrative power. For each one, check the list of active users and remove anyone who no longer needs access. Review recent admin actions, especially new users, role changes, and newly created API keys or integrations. Look for unfamiliar sign-in locations or times that do not match how your team works.
Record the date of each review and what you found, even when the answer is nothing. A short note such as 'Reviewed five tools on the first Monday, removed one inactive contractor, no unusual admin activity' creates a history that helps you spot patterns and proves that the review happened.
A Practical Checklist for Your First Pass
Use this checklist to structure your first review. First, confirm that your inventory lists every tool that holds company data and names an owner for each. Second, for each high-priority tool, locate its activity or audit history and note how far back it goes. Third, ask the vendor the retention, visibility, and export questions described above, and save the replies. Fourth, identify shared logins and integrations with broad access, and decide whether each one should be replaced with individual accounts or narrowed in scope. Fifth, schedule the first monthly review on your calendar with a named person responsible for it.
Compare your results across tools. You may find that one system keeps detailed records and exports them easily, while another keeps very little. That difference should inform where you place your most sensitive data and where you invest your review time. The aim is not to find a perfect tool but to know, clearly and in writing, what you can see and what you cannot.
