What a Cybersecurity Audit Covers in Security Infrastructure

Are cybersecurity audits worth the money for a business that runs cameras, card readers and intrusion alarms?

The Government Accountability Office (GAO) has published an audit guide that gives analysts and auditors methodologies, techniques and audit procedures for evaluating the components of an agency’s cybersecurity program.

For most businesses, the covered components fall into a few groups:

• Cameras, recorders and video management software
• Card access controllers, readers and the credential database
• Intrusion alarm panels and their monitoring connections

Many organizations discover their weakest point is not the camera itself, but the default password on a recorder or a flat network that lets a compromised laptop reach the door controllers.

Why Physical Security Systems Need Cyber Review

Physical security devices are now IP-connected computers. An access controller that talks to a cloud dashboard can be reached by anyone who can reach that network. A camera left on a public address can be found by internet search tools.

Researchers examining cybersecurity audit effectiveness have noted that audits contribute to managing cybersecurity risk when findings are tied to specific controls and owners.

Defining Audit Scope and Systems Inventory

Start by listing every connected device before you decide what to test.

Build the inventory with four fields for each device: make and model, firmware version, network location and the person responsible for it. Record the administrator accounts and where credentials are stored. The audit scope is then the set of devices whose compromise would expose people, data or access to the building.

Exposure matters as much as location. Video systems are a common target for botnet activity, so they deserve close review; our video surveillance services address these exposures.

Watch out: an inventory built only from the IT asset register will miss physical devices that were installed by a vendor and never enrolled.

Cybersecurity Audit Checklist for Cameras, Access Control and Networks

A practical checklist covers the same controls across every device class. Use it as a starting point and adjust for your environment.

• Change default passwords on every camera, recorder, controller and alarm panel
• Confirm firmware is current, and note the date of the last update
• Place cameras and access controllers on a segmented network, separate from office traffic

Procurement also matters. If your government work requires NDAA-compliant equipment, check the manufacturer’s compliance status before you buy, not after installation. NDAA-compliant security cameras are available for clients with those requirements, and a card access system should be checked the same way.

Collecting and Validating Evidence Without Disrupting Operations

Most audit guides tell you which controls to check. Far fewer tell you what to collect, how to prove a control works, and how to do it without knocking a door controller offline at 9 a.m. on a Monday. That gap is where audits quietly fail: the report lists controls, but nothing in the evidence file shows whether the control operated effectively during the review period.

What Evidence to Collect

For each device class in scope, collect the same four evidence types so findings are comparable across cameras, access controllers, alarm panels and the network gear that carries them:

• Configuration evidence, exported configuration files, screenshots of admin settings, firmware version pages, and the current account list with role assignments.
• Log evidence, authentication logs, admin action logs, and any forwarding configuration showing where logs are sent and who can edit them.
• Network evidence, switch port assignments, VLAN membership, firewall rules that reference the device, and results of an external exposure check against your public IP ranges.

A common pattern is to collect configuration and log evidence but skip process evidence entirely. That is how an organization ends up with a finding like “MFA is enabled” when the real question is whether MFA was enforced for every administrator over the whole review period.

Validating a Finding Before It Reaches the Report

A scan result is a lead, not a finding. Validate every candidate finding with a second, independent method and record both methods in the evidence file:

1. Reproduce the exposure from outside the network. If a scan says a recorder is reachable, confirm it from an external address and capture the response, timestamp and source IP used.
2. Confirm the control state directly. If a finding claims default credentials, log in with the documented default, capture the successful authentication, then change it immediately and note the change.
3. Check the compensating control. A device that looks exposed may sit behind a firewall rule, jump host or VPN gateway that already blocks the path. Confirm the rule exists and is enforced, and cite the rule identifier in the evidence.
4. Re-test after remediation. Re-run the same validation method and attach the post-fix evidence to the original finding.

Do not run active vulnerability scans against live access controllers, alarm panels or recorders during business hours. Many of these devices have weak TCP stacks and will drop connections or reboot under scan load, which can lock doors, drop camera streams or trip an alarm. Schedule active testing in a maintenance window with the vendor on the line and a rollback plan documented.

Documenting Control Effectiveness

A finding should answer three questions in one place: what the control is, whether it operated, and how you know. Structure each evidence entry with the device identifier, the control tested, the test method, the result, the date and the reviewer. Keep the file organized by device so a reviewer can trace any line in the report back to a screenshot, a configuration line or a log entry.

Where a control is only partially effective, for example, logs are retained but stored on the same server the administrator controls, say so explicitly and rate it accordingly.

Security Audit Report Template: Findings, Risk Ratings and Remediation Priority

A usable report has four parts: the scope, the findings, the risk rating and the remediation plan. Keep each finding to a single control gap so the owner knows exactly what to fix. The table below is a starting template; the method that follows is what makes the ratings defensible when two owners disagree about what to fix first.

Finding	Risk rating	Remediation	Owner
Default password on recorder	High	Set unique password, store in vault	Facilities
Camera reachable from internet	High	Remove port forward, use VPN	IT
Outdated controller firmware	Medium	Schedule update in maintenance window	Vendor
Former vendor account active	High	Disable account, review audit log	IT
No log retention on alarm panel	Low	Forward logs to central collector	IT

A Repeatable Prioritization Method

Rating findings High, Medium and Low by gut feel produces arguments, not a plan. Use four factors, score each finding on all four, and let the combined score drive the order of work:

• Exploitability, how easy is it for an attacker with no credentials to use this? A default password or an internet-facing device scores highest; a missing log retention policy scores lowest.
• Exposure, how many people or systems can reach the weakness? Internet-facing scores highest, then flat internal networks, then segmented networks with restricted access.
• Business impact, what happens if it is exploited? Consider physical consequences (a door that unlocks, a camera that goes dark), data consequences (recordings or credential databases exposed) and regulatory consequences (notification duties, contractual breach).

A practical scoring approach is to rate each factor 1 to 3 and multiply exploitability by exposure by impact, then use effort as a tiebreaker. The exact scale matters less than applying the same scale to every finding and recording the scores in the report.

Sequencing the Remediation Plan

Once findings are scored, sequence them in three waves:

1. Immediate (within days), internet-facing exposures, default credentials and active former-employee or former-vendor accounts. These are the findings an attacker can use today.
2. Scheduled (within the current maintenance cycle), firmware updates, segmentation changes and log forwarding. These need a change window and often a vendor, so they belong in the next planned outage.
3. Programmatic (within the quarter), policy updates, account review cadence and retention configuration. These are process fixes that prevent the same finding from recurring.

Assign each item an owner and a date. A report without owners tends to stay unread, and a report without dates tends to stay open.

Track a small set of measures across audits so leadership can see progress rather than a fresh list of problems each time: median time to remediate, percentage of critical findings closed on schedule, control coverage across the device inventory, and repeat-finding rate. A repeat-finding rate that stays flat tells you the fixes are being applied but the underlying process is not changing.

Communicating Findings to Leadership

Leadership rarely needs the full finding list. Give them the counts by severity, the measures above, the top three risks in plain language and the decisions you need from them, budget for a segmentation project, authority to enforce MFA, or a vendor change. Keep the technical detail in the appendix so the summary stays short enough to be read.

Cybersecurity Audit Frequency and Video Surveillance Best Practices

Most organizations should audit security infrastructure at least once a year, and again after any major change such as a new recorder, a cloud migration or a vendor switch.

For video surveillance specifically, keep recorders off the general network, rotate administrator passwords on a schedule, review who can export footage, and confirm retention settings match your policy.

Watch out: a common failure is an audit that runs once, passes, and then drifts.

Scheduling Your Infrastructure Audit With Systems Integrations

If you want an outside review, Systems Integrations can scope the audit around your cameras, access control, alarms and the networks that connect them. Our intrusion services can be considered alongside these findings.

Pricing depends on the number of devices, locations and the depth of testing required, so the most accurate figure comes from a site walkthrough. Request a FREE CONSULTATION to get a scoped quote and a clear view of what the audit will cover.

Frequently Asked Questions

What is a cybersecurity audit?

A cybersecurity audit is a structured review of the systems, policies and controls that protect an organization’s data and networks. For security infrastructure, it also covers IP cameras, access control panels, intrusion alarms and the network paths connecting them. Auditors compare the current configuration against a security framework, document gaps such as default passwords or unpatched firmware, and assign risk ratings so the organization knows what to fix first.

How often should security infrastructure be audited?

Most organizations audit security infrastructure at least once a year, and again after major changes such as a new camera deployment, a network upgrade or a change in vendor. Facilities subject to federal contract requirements or regulatory oversight often review more frequently. Continuous monitoring tools can supplement the formal audit, but they do not replace a documented review of configurations, access rights and firmware status.

What should a cybersecurity audit report include?

A useful report lists each finding with its location, evidence, the control it affects, a risk rating and a recommended remediation step with an owner and target date. It should also include the audit scope, the systems inventory reviewed, the methods used and a summary for executives. A clear remediation priority order lets the team address the highest-exposure items, such as internet-facing cameras with default credentials, first.

What is the difference between a cybersecurity audit and a security assessment?

A security assessment identifies vulnerabilities and weaknesses at a point in time, while a cybersecurity audit measures whether controls meet a defined standard and whether they operate as documented. An audit usually produces formal findings and evidence that can be reviewed by auditors or regulators. Many organizations run an assessment first to find issues, then an audit to verify that the remediation actually took effect.
