data security architecture designed using an industry standard

It is a secure application development framework that equips applications with security capabilities for delivering secure Web and e-commerce applications. We then discuss the IPsec protocols for protecting user data: the ESP and the AH. Information and technology power today’s advances, and ISACA empowers IS/IT professionals and enterprises. What follows here is not meant to be a step-by-step breakdown of everything you need to do to create perfect data security; it's an overview of the heavy hitters that come together to create a good foundation for data security. In the IKEv2 protocol, the IKE SAs and IPsec SAs are created between the IP addresses that are used when the IKE SA is established. Originally referred to as the PC bus or AT bus, it was also termed I/O Channel by IBM. There are in fact two versions of IKE: IKE version 1 (IKEv1) and IKE version 2 (IKEv2). The goal of the COBIT 5 framework is to “create optimal value from IT by maintaining a balance between realising benefits and optimising risk levels and resource use.” COBIT 5 aligns IT with business while providing governance around it. Data origin authentication and connection-less integrity are typically used together. Figure 16.39. Figure 8 shows an example of a maturity dashboard for security architecture. Validate your expertise and experience. It is not the intention and ambition of this chapter to provide a complete overview and tutorial on IPsec. The secure channel is called ISAKMP Security Association. Ghaznavi-Zadeh is an IT security mentor and trainer and is author of several books about enterprise security architecture and ethical hacking and penetration, which can be found on Google Play or in the Amazon store. The CMMI model has five maturity levels, from the initial level to the optimizing level.6 For the purpose of this article, a nonexistent level (level 0) is added for those controls that are not in place (figure 7). The SA database that contains parameters associated with each active SA. SABSA is a business-driven security framework for enterprises that is based on risk and opportunities associated with it. However, it does not detect if the packets have been duplicated (replayed) or reordered. Applying those principles to any architecture ensures business support, alignment and process optimization.3. IP Packet (Data) Protected by ESP. The scheme uses a security context transfer mechanism to achieve its goal for trusted non-3GPP networks. 2 Thomas, M.; “The Core COBIT Publications: A Quick Glance,” COBIT Focus, 13 April 2015, www.isaca.org/Knowledge-Center/Research/Documents/COBIT-Focus-The-Core-COBIT-Publications-A-Quick-Glance_nlt_Eng_0415.pdf Contribute to advancing the IS/IT profession as an ISACA member. The two peers agree on authentication and encryption methods, exchange keys, and verify the other's identity. The data origin authentication service allows the receiver of the data to verify the identity of the claimed sender of the data. This Quick Start sets up an AWS Cloud environment that provides a standardized architecture for Payment Card Industry (PCI) Data Security Standard (DSS) compliance. Rassoul Ghaznavi-Zadeh, CISM, COBIT Foundation, SABSA, TOGAF RFC 4301 is an update of the previous IPsec security architecture specification found in IETF RFC 2401. (On this high level, the procedure is similar for IKEv1 and IKEv2.) The main hardware components of a computer system are the CPU, primary and secondary memory, and input/output devices. ESP can provide integrity and confidentiality while AH only provides integrity. Many of the quantifications resulting from the risk analysis tools and techniques may be useful to the business owner outside of this process as well. It is purely a methodology to assure business alignment. The Data part of the ESP packet in Figure 16.38 now corresponds to a complete IP packet, including the IP header. No matter how broad or deep you want to go or take your team, ISACA has the structured, proven and flexible training options to take you from any level to new heights and destinations in IT audit, risk management, control, information security, cybersecurity, IT governance and beyond. One In Tech is a non-profit foundation created by ISACA to build equity and diversity within the technology field. Whereas the verification of a checksum value or an error detecting code, as those produced by the CRC algorithms or the frame check sequence (FCS), is designed to detect only accidental modifications of the data. REST is an architectural style for building distributed systems based on hypermedia. For you to successfully use the IPSec protocol, two gateway systems must negotiate the algorithms used for authentication and encryption. On other interfaces in EPS, however, it is primarily IKEv2 that is used. Improvements have, for example, been made in terms of reduced complexity of the protocol, simplification of the documentation (one RFC instead of three), reduced latency in common scenarios, and support for Extensible Authentication Protocol (EAP) and mobility extensions (MOBIKE). The IPsec SA for ESP has been set up using IKEv2 (see Section 10.10 for more details). The IPsec security architecture is defined in IETF RFC 4301. Moreover, some of the security services defined by ISO are probably not very likely to be useful on the context of some fieldbuses. Like any other framework, the enterprise security architecture life cycle needs to be managed properly. IKE is used for authenticating the two parties and for dynamically negotiating, establishing, and maintaining SAs. Control tables: A set of tables that define the action items the … The access control service protects the system resources against non-authorized users. How to Use This Guide¶ This NIST Cybersecurity Practice Guide demonstrates a standards-based reference design and provides users with the information they need to replicate this approach to mobile security. In phase 2, another SA is created that is called the IPsec SA in IKEv1 and child SA in IKEv2 (for simplicity we will use the term IPsec SA for both versions). Unlike IPSec SAs, ISAKMP SAs are bidirectional and the same keys and algorithms protect inbound and outbound communications. The world has changed; security is not the same beast as before. Our community of professionals is committed to lifetime learning, career progression and sharing expertise for the benefit of individuals and organizations around the globe. IKEv2 also supports the use of the EAP and therefore allows a more wide range of credentials to be used, such as SIM cards (see Section 16.10 for more information on EAP). The specification was refined through the Open Group standards process with companies such as Hewlett-Packard, IBM, JP Morgan, Motorola, Netscape, Trusted Information Systems, and Shell Companies. ISACA® offers training solutions customizable for every area of information systems and cybersecurity, every experience level and every style of learning. Figure 16.41. Each layer has a different purpose and view. Common data security architecture (CDSA) is a set of security services and frameworks that allow the creation of a secure infrastructure for client/server applications and services. That can be accomplished by assigning to each slave node in the network a unique private key and a master node’s public key. Instead, we will give a high-level introduction to the basic concepts of IPsec focusing on the parts of IPsec that are used in EPS. Copyright © 2020 Elsevier B.V. or its licensors or contributors. fast security algorithms requiring a small amount of memory. This secure architecture design is the result of an evolutionary process of technology advancement and increasing cyber vulnerability presented in the Recommended Practice document, Control Systems Defense in Depth Strategies. A sound security architecture and the implementing technologies that have been discussed in previous chapters address only part of the challenge. After the program is developed and controls are being implemented, the second phase of maturity management begins. A security model is a statement that out-lines the requirements necessary to properly support and implement a certain security policy. This phase is protected by the IKE SA established in phase 1. MULTISAFE: a data security architecture MULTISAFE: a data security architecture Trueblood, Robert P.; Hartson, H. Rex 1981-06-01 00:00:00 MULTISAFE--A DATA SECURITY ARCHITECTURE by Robert P. Trueblood H. Rex Hartson* Department of Computer Science University of South Carolina Columbia, South Carolina 29208 I NTR ODUCT ION ~FULTISAFE is a MULTl-module thorizations architecture … Many information security professionals with a traditional mind-set view security architecture as nothing more than having security policies, controls, tools and monitoring. This chapter examines security considerations in all phases of the Smart Grid system development lifecycle, identifying industrial best practices and research activities, and describes a system development lifecycle process with existing and emerging methods and techniques for Smart Grid security. Eric Conrad, ... Joshua Feldman, in CISSP Study Guide (Second Edition), 2012. Security Architecture and Design describes fundamental logical hardware, operating system, and software security components and how to use those components to design, architect, and evaluate secure computer systems. Data is usually one of several architecture domains that form the pillars of an enterprise architecture or solution architecture. ISACA membership offers these and many more ways to help you all career long. To really make this process effective, supplementary documentation will need to be provided, including workflows and worksheets to aid business owners with the task of determining a system's risk profile and evaluating its risk exposure. Security Architecture and Design: The design and architecture of security services, which facilitate business risk exposure objectives. Zhendong Ma, ... Paul Murdock, in Smart Grid Security, 2015. To ensure security in Smart Grid, from development via roll-out to operation, proven development processes and management are needed to minimize or eliminate security vulnerabilities that are introduced in the development lifecycle. Regardless of the methodology or framework used, enterprise security architecture in any enterprise must be defined based on the available risk to that enterprise. 6 CMMI Institute, “CMMI Maturity Levels,” http://cmmiinstitute.com/capability-maturity-model-integration. Security Architecture and Design is a three-part domain. data security requirements. Allocating management, operational, and technical security controls to information systems and environments of operation as defined by the information security architecture. Connect with new tools, techniques, insights and fellow professionals around the world. An SA is the relation between the two entities, defining how they are going to communicate using IPsec. The mechanism to achieve confidentiality with IPsec is encryption, where the content of the IP packets is transformed using an encryption algorithm so that it becomes unintelligible. Mandatory IKE parameters are: Authentication method: Pre-Shared Key and X.509 Certificates. IT Total Cost of Ownership (TCO) as a Percentage of Revenue One of EA's value propositions is reducing costs by leveraging common solutions and rationalizing processes, technology and data. Where EA frameworks distinguish among separate logical layers such as business, data, application, and technology, security architecture often reflects structural layers such as physical, network, platform, application, and user. The gateways must self-authenticate and choose session keys that will secure the traffic. Understanding these fundamental issues is critical for an information security professional. The Internet Key Exchange (IKE) is implemented on top of UDP, port 500. Each layer has a different purpose and view. implement industry standard mobile security controls, reducing long-term costs and decreasing the risk of vendor lock-in ; 2. What a best practice looks like for your business will depend on many factors, such as size, industry, location, and existing tools and policies. IPsec also defines a nominal Security Policy Database (SPD), which contains the policy for what kind of IPsec service is provided to IP traffic entering and leaving the node. The outcome of this phase is a maturity rating for any of the controls for current status and desired status. Another difference is that ESP only protects the content of the IP packet (including the ESP header and part of the ESP trailer), while AH protects the complete IP packet, including the IP header and AH header. The TOGAF framework is useful for defining the architecture goals, benefits and vision, and setting up and implementing projects to reach those goals. A new IKEv2 authentication and IPsec SA establishment have to be performed. Another example is a scenario where a mobile UE changes its point of attachment to a network and is assigned a different IP address in the new access. The first phase measures the current maturity of required controls in the environment using the Capability Maturity Model Integration (CMMI) model. ISACA delivers expert-designed in-person training on-site through hands-on, Training Week courses across North America, through workshops and sessions at conferences around the globe, and online. It operates at the IP layer, offers protection of traffic running above the IP layer, and it can also be used to protect the IP header information on the IP layer. ISACA® membership offers you FREE or discounted access to new knowledge, tools and training. Translating architectural information security requirements into specific security controls for information systems and environments of operation. Security Architecture for IP (RFC 2401) defines a model with the following two databases: The security policy database that contains the security rules and security services to offer to every IP packet going through a secure gateway. IKE parameters are negotiated as a unit and are termed a protection suite. Meet some of the members around the world who make ISACA, well, ISACA. Beyond certificates, ISACA also offers globally recognized CISA®, CRISC™, CISM®, CGEIT® and CSX-P certifications that affirm holders to be among the most qualified information systems and cybersecurity professionals in the world. By using a combination of the SABSA frameworks and COBIT principles, enablers and processes, a top-down architecture can be defined for every category in figure 2. In a nutshell, DSS requires that your organization is … Using these frameworks can result in a successful security architecture that is aligned with business needs: The simplified agile approach to initiate an enterprise security architecture program ensures that the enterprise security architecture is part of the business requirements, specifically addresses business needs and is automatically justified. Here are a few metrics that might work: 1. The SPI is present in both ESP and AH headers, and is a number that, together with the destination IP address and the security protocol type (ESP or AH), allows the receiver to identify the SA to which the incoming packet is bound. An SA is unidirectional, so to provide IPsec protection of bidirectional traffic a pair of SAs is needed, one in each direction. ISAKMP typically uses IKEv1 for key exchange, but could be used with other key exchange protocols. To provide security of handovers, the work in [ZHE 05] proposed a hybrid AKA scheme that supported global mobility. One mode is defined for phase 2. The Data field as depicted in Figure 16.38 would then contain, for example, a UDP or TCP header as well as the application data carried by UDP or TCP. Our certifications and certificates affirm enterprise team members’ expertise and build stakeholder confidence in your organization. Available 24/7 through white papers, publications, blog posts, podcasts, webinars, virtual summits, training and educational forums and more, ISACA resources.

Participate in ISACA chapter and online groups to gain new insight and expand your professional influence. In EPS, this may occur if a user is using WLAN to connect to an ePDG. Implementing security architecture is often a confusing process in enterprises. Incorporating an information security architecture that implements architectural information security requirements within and across information systems. Gain a competitive edge as an active informed professional in information systems, cybersecurity and business. The SABSA methodology has six layers (five horizontals and one vertical). The SPI can be seen as an index to a Security Associations database maintained by the IPsec nodes and containing all SAs. In this phase, the ratings are updated and the management team has visibility of the progress. Microsoft uses industry standard technologies such as TLS and SRTP to encrypt all data in transit between users' devices and Microsoft datacenters, and between Microsoft datacenters. Today’s risk factors and threats are not the same, nor as simple as they used to be. Security Architecture and Design describes fundamental logical hardware, operating system, and software security components and how to use those components to design, architect, and evaluate secure computer systems. Start your career among a talented community of professionals. In the next section we give an overview of basic IPsec concepts. Miguel Leόn Chávez, Francisco Rodríguez Henríquez, in, Fieldbus Systems and Their Applications 2005, Magnus Olsson, ... Catherine Mulligan, in, EPC and 4G Packet Networks (Second Edition). The verification of the hash code is designed to detect intentional and unauthorized modifications of the data, as well as accidental modifications. application, data, infrastructure architecture (hardware, systems, and networks), and security. Get in the know about all things information systems and cybersecurity. Data Architecture Standards Ministry of Education Information Security Classification: Low Page 3 • Data Architecture standards (defined in this document and elsewhere on BPP site) are part of the overall Business Program Planning (BPP) standards of the Ministry. 3 Op cit, ISACA This includes messages, files, meetings, and other content. And on the other hand, public key cryptography requires complex algorithms, large key-sizes, and management of the public keys. The confidentiality service protects the data against non-authorized revelations. Learn why ISACA in-person training—for you or your team—is in a class of its own. COBIT 5, from ISACA, is “a comprehensive framework that assists enterprises in achieving their objectives for the governance and management of enterprise IT.”1 This framework includes tool sets and processes that bridge the gap between technical issues, business risk and process requirements. q Sharing of data greatly reduces data entry and maintenance efforts. The IPsec SAs are used for the IPsec protection of the data using ESP or AH. ESP and AH are typically used separately but it is possible, although not common, to use them together. Example of IP Packet Protected Using ESP in Transport Mode. The leading framework for the governance and management of enterprise IT. Build your team’s know-how and skills with customized training. REST is independent of any underlying protocol and is not necessarily tied to HTTP. Although the previous limited security schemes have a cheaper price, some fieldbuses may not be able to afford them. Once the necessary controls have been identified in step 3, a gap analysis should be included to determine whether current controls in place meet the same standard and intent, or whether additional controls are needed. The SPD contains entries that define a subset of IP traffic, for example using packet filters, and points to an SA (if any) for that traffic. LTE security architecture benefits from key freshness techniques used in the handover process to prevent security threats from malicious eNBs. MOBIKE is defined in IETF RFC 4555. See Figures 16.38 and 16.39 for illustrations of ESP- and AH-protected packets. The MOBIKE protocol extends IKEv2 with possibilities to dynamically update the IP address of the IKE SAs and IPsec SAs. Beyond training and certification, ISACA’s CMMI® models and platforms offer risk-focused programs for enterprise and product assessment and improvement. The user traffic between the UE and the ePDG (i.e. After that we discuss the Internet Key Exchange (IKE) protocol used for authentication and establishing IPsec Security Associations (SAs). The CMMI model is useful for providing a level of visibility for management and the architecture board, and for reporting the maturity of the architecture over time. Build on your expertise the way you like with expert interaction on-site or virtually, online through FREE webinars and virtual summits, or on demand at your own pace. See Figure 16.40 for an illustration of a UDP packet that is protected using ESP in transport mode. Define physical architecture and map with conceptual architecture: Database security, practices and procedures. The exchange of this information creates a security association (SA), which is a policy and set of keys used to protect a one-way communication. COBIT principles and enablers provide best practices and guidance on business alignment, maximum delivery and benefits. A security policy outlines how data is accessed, what level of security is required, and what actions should be taken when these requirements are not met. However, if an eNB is compromised, the adversary is able to modify Next-Hop Chaining Counter (NCC) and as a result the synchronization between UE and target eNB is disrupted. Detection and rejection of replays is a form of partial sequence integrity, where the receiver can detect if a packet has been duplicated. Whether you are in or looking to land an entry-level position, an experienced IT practitioner or manager, or at the top of your field, ISACA® offers the credentials to prove you have what it takes to excel in your current and future roles. The node may want to use a different interface in case the currently used interface suddenly stops working. If the user now moves to a different network (e.g. CDSA was adopted by the The COBIT framework is based on five principles (figure 3). Companies enact a data security policy for the sole purpose of ensuring data privacy or the privacy of their consumers' information. By using SABSA, COBIT and TOGAF together, a security architecture can be defined that is aligned with business needs and addresses all the stakeholder requirements. For untrusted non-3GPP networks, the authors proposed a pre-authentication approach. As an example, when developing computer network architecture, a top-down approach from contextual to component layers can be defined using those principles and processes (figure 4). After all risk is identified and assessed, then the enterprise can start designing architecture components, such as policies, user awareness, network, applications and servers. The integrity service can be achieved also by using a one-way hash function optimized for heavily constrained environments, as those typically found in fieldbuses. For more details on S2c and SWu, see Sections 15.5.1 and 15.10.1Section 15.5.1Section 15.10.1 respectively. on the SWu interface) is protected using ESP in tunnel mode. EPS uses IPsec to secure communication on several interfaces, in some cases between nodes in the core network and in other cases between the UE and the core network. Security architecture standards are based on the policy statements and they lay out a set of requirements that show how the organization implements these policies. Data-centric architecture. However, most common REST implementations use HTTP as the application protocol, and this guide focuses on designing REST APIs for HTTP. It is important to update the business attributes and risk constantly, and define and implement the appropriate controls. Security Services in Fieldbuses: At What Cost? SABSA does not offer any specific control and relies on others, such as the International Organization for Standardization (ISO) or COBIT processes. Every packet exchanged in phase 2 is authenticated and encrypted according to keys and algorithms selected in the previous phase. Previous versions of ESP and AH are defined in IETF RFC 2406 and 2402 respectively. The work in [RAJ 08] presented a method to address handover issues between 3GPP networks and non-3GPP networks. The COBIT Process Assessment Model (PAM) provides a complete view of requirement processes and controls for enterprise-grade security architecture. The policy outlines the expectations of a computer system or device. The life cycle of the security program can be managed using the TOGAF framework. IPsec provides security services for both IPv4 and IPv6. We use cookies to help provide and enhance our service and tailor content and ads. Organizations need standards, guidelines, and other publications in order to effectively and efficiently manage their security programs, protect their information and information systems, and protect patient privacy. CDSA was originally developed by Intel Architecture Lab (IAL). The first part covers the hardware and software required to have a secure computer system, the second part covers the logical models required to keep the system secure, and the third part covers evaluation models that quantify how secure the system really is. Integrity and non-repudiation can be obtained by signing/verifying all the messages transmitted between a particular slave node and the master node. This can be done manually by simply configuring both parties with the required parameters. Enterprise Architecture is still an emerging field. The contextual layer is at the top and includes business requirements and goals. Likewise our COBIT® certificates show your understanding and ability to implement the leading global framework for enterprise governance of information and technology (EGIT). The primary difference here is that, for existing systems, applications, or environments, active vulnerability assessments can be performed to educate the risk exposure calculations. As a result, the handover will fail since the NCC stored in UE is not consistent with the one it received. The fields in the ESP and AH headers are briefly described below. Also, mutual authentication of the two parties takes place during phase 1. Some enterprises are doing a better job with security architecture by adding directive controls, including policies and procedures. After phase 2 is completed, the two parties can start to exchange traffic using EPS or AH. The ISA term … Andrew Hay, ... Warren Verbanec, in Nokia Firewall, VPN, and IPSO Configuration Guide, 2009. In order to use the IPsec services between two nodes, the nodes use certain security parameters that define the communication, such as keys, encryption algorithms, and so on. More certificates are in development. See Figure 16.41 for an illustration of a UDP packet that is protected using ESP in tunnel mode. This section describes a simple and practical example of the steps that can be taken to define a security architecture for an enterprise. This is where Internet Key Exchange (IKE) comes into the picture. The receiver computes the integrity check value for the received packet and compares it with the one received in the ESP or AH packet. Defining the appropriate architectural information security requirements based on the organization’s risk management strategy. The one method to complete phase 1 is Main Mode. The resulting documentation step would then include a plan for applying controls based on priority or risk and the effort involved, and this plan would then be carried out in the implementation step. Enterprise Information Systems Security Architecture (EISSA), a component of EITA, forms the overall physical and logical components that make up security architecture in the organization. The Security Architecture of the OSI Reference Model (ISO 7498-2) considers five main classes of security services: authentication, access control, confidentiality, integrity and non-repudiation. Then, in future instances, it sends previously collected requests to a new eNB when a UE would like to move to the target eNB. TOGAF is a useful framework for defining the architecture, goals and vision; completing a gap analysis; and monitoring the process. In 2000, Roy Fielding proposed Representational State Transfer (REST) as an architectural approach to designing web services.
