A server room contains the digital core of your organization and therefore deserves at least the same security as a safe. In this article, we answer the most frequently asked questions about server room security, from vulnerabilities to access policy. Would you like immediate, tailored advice? <a href=\"https:\/\/www.sellox.nl\/en\/contact\/\">Feel free to contact us<\/a> with Sellox.<\/p>\n<h2>Which physical security measures best protect a server room?<\/h2>\n<p>The most effective physical measures for a server room are a certified security door, burglar-resistant walls, an electronic locking mechanism, and an alarm system that responds immediately to unauthorized entry attempts. These layers work together to deter both opportunistic intruders and targeted attacks.<\/p>\n<p>Good server room security starts with the construction of the room itself. Standard interior walls and ordinary doors offer little resistance. Opt for steel doors with a certified burglary resistance class and reinforce the walls and ceiling where necessary. Combine this with an electronic access system so you always know who enters and when.<\/p>\n<p>In addition to the door, the following measures are also essential:<\/p>\n<ul>\n <li>Server cabinets with separate lock for an extra layer of security<\/li>\n <li>Motion detectors inside the room<\/li>\n <li>Fire protection and water detection to prevent damage from calamities<\/li>\n <li>Emergency power supply so that security systems remain active even during a power outage.<\/li>\n<\/ul>\n<h2>What are the most common weak points in server room security?<\/h2>\n<p>The most common weak points are shared access codes, unattended visitor access, outdated locks, and the lack of a log of who has entered the space. Many organizations invest in technology but forget the human and procedural aspects of security.<\/p>\n<p>A shared PIN code or a key used by multiple employees makes it impossible to determine afterwards who was responsible for an incident. The same applies to suppliers or technicians who gain unsupervised access to the server room. They are unfamiliar with the internal procedures and therefore pose an unwitting risk.<\/p>\n<p>Other common problems are:<\/p>\n<ul>\n <li>Access passes that are not collected upon the departure of employees<\/li>\n <li>Doors that do not automatically lock after use<\/li>\n <li>No separation between IT staff and other personnel<\/li>\n <li>Missing or non-functioning camera surveillance<\/li>\n<\/ul>\n<h2>How does access control for a server room work?<\/h2>\n<p>Access control for a server room works by means of a system that verifies a person&#039;s identity before granting access. This can be done via a card, PIN code, biometric feature, or a combination thereof. Every access moment is recorded, ensuring that a complete overview is always available.<\/p>\n<p>Modern <a href=\"https:\/\/www.sellox.nl\/en\/access-control\/\">access control<\/a> It makes it possible to set rights per person, per time, and per location. A system administrator is granted access during all hours, while a cleaning employee is only allowed in at set times and preferably accompanied. This principle is called the least-privilege principle: everyone receives exactly the access needed for their task, and no more.<\/p>\n<p>A well-configured access control system includes the following elements:<\/p>\n<ul>\n <li>Unique identification per user, so that access is always traceable<\/li>\n <li>Automatic locking after a set period of inactivity<\/li>\n <li>Real-time notifications for unauthorized access attempts<\/li>\n <li>Central management environment to quickly modify or revoke rights<\/li>\n<\/ul>\n<h2>When is camera surveillance mandatory in a server room?<\/h2>\n<p>Camera surveillance in a server room is not always legally required, but may stem from sector-specific standards, contractual obligations, or certifications such as ISO 27001 or NEN 7510. In practice, organizations working with sensitive personal data or critical infrastructure almost always have an obligation to implement camera surveillance.<\/p>\n<p>Under the GDPR, strict rules apply regarding how camera surveillance is deployed. Camera footage may only be used for the purpose for which it was installed, employees must be aware of the surveillance, and footage may not be retained longer than necessary. A retention period of four weeks is the maximum in most cases.<\/p>\n<p>Regardless of the legal obligation, camera surveillance is highly recommended. Camera footage constitutes crucial evidence in the event of incidents and simultaneously has a preventative effect: the presence of cameras deters potential intruders.<\/p>\n<h2>What role does a security company play in securing a server room?<\/h2>\n<p>A security company advises on the right combination of measures, installs and manages security systems, and can provide alarm response if necessary. In doing so, the company assumes technical and operational responsibility, allowing the organization to focus on its core activities.<\/p>\n<p>A specialized company first conducts a risk analysis to determine which threats are most relevant to your situation. Based on this, a security plan is drawn up that aligns with the size of the organization, the sensitivity of the data, and the available budget. This prevents investments in measures that do not match the actual risk profile.<\/p>\n<p>In addition to the initial installation, a security company also offers:<\/p>\n<ul>\n <li>Periodic maintenance and testing of all security systems<\/li>\n <li>24\/7 alarm response for incidents<\/li>\n <li>Advice on changes to the organization or the building<\/li>\n <li>Support with audits and certification processes<\/li>\n<\/ul>\n<h2>How do you set up an access policy for the server room?<\/h2>\n<p>You establish an access policy for the server room by defining who has access, under what conditions, how access is granted and revoked, and how access times are recorded and monitored. The policy must be established in writing and reviewed periodically.<\/p>\n<p>Start with an overview of all positions and roles within the organization that require access to the server room. Determine the minimum access level required for each role. Next, establish the procedure that applies to the onboarding of new employees, job changes, and terminations. It is precisely at these moments that things frequently go wrong in practice.<\/p>\n<p>A complete access policy contains at least the following components:<\/p>\n<ol>\n <li>A list of authorized persons with associated access rights<\/li>\n <li>A procedure for requesting and approving access<\/li>\n <li>Rules for guiding visitors and external parties<\/li>\n <li>A logbook requirement and the frequency of checks on access records<\/li>\n <li>Sanctions for violation of the policy<\/li>\n <li>A review cycle, at least once a year<\/li>\n<\/ol>\n<p>A good access policy is not a one-off document, but a living instrument that grows with the organization. Preferably, have the policy reviewed by an external party to identify blind spots. <a href=\"https:\/\/www.sellox.nl\/en\/contact\/\">Contact us<\/a> Contact Sellox for a no-obligation consultation on the security of your server room.<\/p>\n<div class=\"wp-block-seoaic-faq-block\">\n    <h2 class=\"seoaic-faq-section-title\">Frequently Asked Questions<\/h2>\n            <div class=\"seoaic-faq-item\">\n            <h3 class=\"seoaic-question\">\n                How often should I have the security of my server room checked?            <\/h3>\n            <p class=\"seoaic-answer\">\n                It is recommended to perform a full security audit of your server room at least once a year, preferably by an external party that can objectively assess where the weak points lie. Additionally, it is advisable to have an interim check performed after every major organizational or structural change. Examples include renovations, mergers, or a significant expansion of the workforce.            <\/p>\n        <\/div>\n                <div class=\"seoaic-faq-item\">\n            <h3 class=\"seoaic-question\">\n                What should I do if an employee with server room access leaves the organization?            <\/h3>\n            <p class=\"seoaic-answer\">\n                As soon as an employee leaves the company, all access rights to the server room must be revoked immediately \u2014 preferably on the last working day or earlier. This entails deactivating access passes, removing biometric data from the system, and changing any shared PINs. Document this procedure in writing in the access policy so that HR and IT are always in sync when an employee leaves.            <\/p>\n        <\/div>\n                <div class=\"seoaic-faq-item\">\n            <h3 class=\"seoaic-question\">\n                Is a biometric access system more secure than a card or PIN code for the server room?            <\/h3>\n            <p class=\"seoaic-answer\">\n                Biometric systems generally offer a higher level of security because they measure something unique to the individual, such as a fingerprint or iris scan, making them more difficult to copy or share than a card or PIN code. The disadvantage is that biometric data is considered special personal data under the GDPR, which entails additional legal obligations. The most robust solution is a combination of two factors, such as a card and a PIN code or biometrics, also known as multifactor authentication.            <\/p>\n        <\/div>\n                <div class=\"seoaic-faq-item\">\n            <h3 class=\"seoaic-question\">\n                How do I deal with external technicians or suppliers who need access to the server room?            <\/h3>\n            <p class=\"seoaic-answer\">\n                External parties must never be granted access to the server room without supervision. Always designate an internal responsible person to accompany the visitor throughout the entire visit and supervise the work performed. Record the visit in the access log with name, company, time of entry and exit, and the purpose of the visit. Additionally, consider having external parties sign a confidentiality agreement before being granted access.            <\/p>\n        <\/div>\n                <div class=\"seoaic-faq-item\">\n            <h3 class=\"seoaic-question\">\n                What are the costs of a professional server room security system?            <\/h3>\n            <p class=\"seoaic-answer\">\n                Costs vary widely depending on the size of the space, the desired level of security, and the chosen combination of measures such as camera surveillance, access control, and alarm response. A basic solution for a small server room typically starts at a few thousand euros for installation, while a fully configured system with 24\/7 monitoring and advanced access control can be significantly more expensive. A risk analysis by a specialized security company helps you align the investment with your organization&#039;s actual risk profile, ensuring you do not over- or underinvest.            <\/p>\n        <\/div>\n                <div class=\"seoaic-faq-item\">\n            <h3 class=\"seoaic-question\">\n                Which certifications or standards are relevant for server room security?            <\/h3>\n            <p class=\"seoaic-answer\">\n                The most relevant standards are ISO 27001 for information security in general and NEN 7510 for organizations in the healthcare sector that work with medical personal data. In addition, the European Union applies the NIS2 Directive, which is becoming mandatory for an increasing number of sectors and sets requirements for the physical security of critical IT infrastructure. Obtaining such certification not only demonstrates that your security is in order but also gives customers and partners confidence in how your organization handles sensitive data.            <\/p>\n        <\/div>\n                <div class=\"seoaic-faq-item\">\n            <h3 class=\"seoaic-question\">\n                What should I do if an unauthorized access attempt has occurred?            <\/h3>\n            <p class=\"seoaic-answer\">\n                Immediately activate your organization&#039;s incident response plan and ensure that the affected systems and access logs are secured as evidence. Inform the relevant internal stakeholders, such as the IT manager and management, and involve the police if necessary. Subsequently, analyze how the attempt was possible and which security measures need to be tightened to prevent recurrence. If a data breach has resulted from the incident, in many cases you are required to report this to the Dutch Data Protection Authority within 72 hours.            <\/p>\n        <\/div>\n        <\/div>","protected":false},"excerpt":{"rendered":"<p>Bescherm je serverruimte met bewezen beveiligingslagen \u2014 van toegangsbeleid tot camerabewaking.
