Tier 1 is the simplest architecture, while Tier 4 is a robust architecture with redundancy at all levels and hence is less prone to failures. In addition to fencing (discussed in the previous section), barricades are used to control … Video content analytics (VCA) can detect individuals and objects and check for any illegal activity. For example, a hacker may decide to use a malware, or malicious software, to bypass the various firewalls and gain access to the organization’s critical information. Layers provide a structured pattern of physical protection, thus making it easy to analyze a failure. Second, physical locations should be monitored using surveillance cameras and notification systems, such as intrusion d… A Data Center is basically a building or a dedicated space which hosts all critical systems or Information Technology infrastructure of an organization. Ineffective implementation of redundancy for critical systems. A Tier 4 data center is completely fault tolerant and has redundant hot standby for every component and utility source. This can be achieved through a high-resolution video surveillance system, motion-activated security lighting, fiber-optic cable, etc. Please send us your comments and questions about this topic to [email protected] Authorized staff utilize … February 26, 2019. Barricades. water leakage detector panel to monitor for any water leakage in the server room. Security guards are fundamental elements of physical security because all other security controls, whether active surveillance or detection mechanisms, rely on these guards to deter physical attacks and intrusions. Figure 3. For auditors and consultants: Learn how to perform a certification audit. Each of these tiers can be defined precisely (figure 2). Usage of strong passwords and secure usernames which are encrypted via 256-bit SSL, and not storing them in plain text, set up of scheduled expirations, prevention of password reuse, AD (Active Directory)/LDAP (Lightweight Directory Access Protocol) integration, Controls based on IP (Internet Protocol) addresses, Encryption of the session ID cookies in order to identify each unique user, Frequent third party VAPT (Vulnerability and Penetration Testing), Malware prevention through firewalls and other network devices. To understand the access control in ISO 27001, please read the article How to handle access control according to ISO 27001. To understand the importance of ISO 27001 certification from the perspective of a CEO of an independent Data Center, read the article ISO 27001 Case study for data centers: An interview with Goran Djoreski. Introduction to Physical Security. Kevin Grzelka, CTIA, CISSP Data Center & Infrastructure Engineer, Solution Delivery, Data Center & Infrastructure Engineering . Unplanned maintenance does not cause disruption in service. Data Center Entry Points Physical access is controlled at building ingress points by professional security staff utilizing surveillance, detection systems, and other electronic means. Tier 1 is a type of data center that has a single path for utility sources, such as power and cooling requirements. An integrated IP network of the four layers of security can create an effective, efficient, and comprehensive system for any application. Physical controls include perimeter monitoring, motion detection, and intrusion alarms. The security measures can be categorized into four layers: perimeter security, facility controls, computer room controls, and cabinet controls. The physical security of a Data Center is the set of protocols that prevent any kind of physical damage to the systems that store the organization’s critical data. Engineering plan and space design of data center. Unauthorized access and usage of computing resources. Split units or variable refrigerant flow might also be used for temperature control. The first layer of data center security is to discourage, detect, and delay any unauthorized entry of personnel at the perimeter. Those locks should be electronic, so you can audit access and control authorization. The inner layers also help mitigate insider threats. The following are examples of the most common threats to Data Centers: The most common weaknesses in Data Centers are related to the following areas: Based on the list of risks identified, each risk shall be mapped to security controls, that can be chosen from ISO 27001 (Annex A controls) or security controls from other local/international information security standards. Controls include administrative decisions such as site location, facility design, and employee control/assigning the access level. To prevent any physical attacks, the following need to be considered: Organizations should monitor the safety and security of the data center rack room with authenticated access through the following systems: Raised floor systems are required to route cables and chilled-air piping and ducting beneath data center racks. Security controls for Data Centers are becoming a huge challenge due to increasing numbers of devices and equipment being added. Now that we’ve explored the physical security practices crucial for data … Efficient network security. Administrative controls include construction, site location, emergency response and technical controls include CCTV, smart cards for access, guards while physical controls consist of intrusion alarms, perimeter security.
