data security architecture designed using an industry standard

In order to communicate using IPsec, the two parties need to establish the required IPsec SAs. The SPI can be seen as an index to a Security Associations database maintained by the IPsec nodes and containing all SAs. SABSA does not offer any specific control and relies on others, such as the International Organization for Standardization (ISO) or COBIT processes. In the base IKEv2 protocol, it is not possible to change these IP addresses after the IKE SA has been created. 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. 4 The Open Group, “Welcome to TOGAF 9.1, an Open Group Standard, http://pubs.opengroup.org/architecture/togaf9-doc/arch/ For more details on S2c and SWu, see Sections 15.5.1 and 15.10.1Section 15.5.1Section 15.10.1 respectively. IPsec provides security services for both IPv4 and IPv6. The bus was backward compatible with the 8-bit bus of the 8088-based IBM PC, including the IBM PC/XT as well as IBM PC compatibles. The Main Mode negotiation uses six messages, in a triple two-way exchange. Quick Mode uses three messages, two for proposal parameters and a third to acquit the choice. One example is a multi-homing node with multiple interfaces and IP addresses. In the next section we give an overview of basic IPsec concepts. Hamidreza Ghafghazi, ... Carlisle Adams, in Wireless Public Safety Networks 2, 2016. In information technology, data architecture is composed of models, policies, rules or standards that govern which data is collected, and how it is stored, arranged, integrated, and put to use in data systems and in organizations. 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. The aim is to define the desired maturity level, compare the current level with the desired level and create a program to achieve the desired level. To protect data in transit between Dropbox apps (currently desktop, mobile, API, or web) and our servers, Dropbox uses Secure Sockets Layer (SSL)/Transport Layer Security (TLS) for data transfer, creating a secure tunnel protected by 128-bit or higher Advanced Encryption Standard (AES) encryption. The same security architecture risk analysis workflow described above applies to the general process for bringing legacy resources into compliance with the security architectural standards. Enterprise Security Architecture—A Top-down Approach, www.isaca.org/COBIT/Pages/COBIT-5-Framework-product-page.aspx, www.isaca.org/Knowledge-Center/Research/Documents/COBIT-Focus-The-Core-COBIT-Publications-A-Quick-Glance_nlt_Eng_0415.pdf, http://pubs.opengroup.org/architecture/togaf9-doc/arch/, http://pubs.opengroup.org/architecture/togaf9-doc/arch/chap05.html, http://cmmiinstitute.com/capability-maturity-model-integration, Identify business objectives, goals and strategy, Identify business attributes that are required to achieve those goals, Identify all the risk associated with the attributes that can prevent a business from achieving its goals, Identify the required controls to manage the risk. 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. SABSA does not offer any specific control and relies on others, such as the International Organization for Standardization (ISO) or COBIT processes. 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. The language used … 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. After phase 2 is completed, the two parties can start to exchange traffic using EPS or AH. In EPS, this may occur if a user is using WLAN to connect to an ePDG. Integrity and non-repudiation can be obtained by signing/verifying all the messages transmitted between a particular slave node and the master node. 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. With “perfect forward secrecy” enabled, the default value in Nokia's configuration, a new Diffie-Hellman exchange must take place during Quick Mode. Today, we also help build the skills of cybersecurity professionals; promote effective governance of information and technology through our enterprise governance framework, COBIT® and help organizations evaluate and improve performance through ISACA’s CMMI®. Identifying where effective risk response is a critical element in the success of organizational mission and business functions. Andrew Hay, ... Warren Verbanec, in Nokia Firewall, VPN, and IPSO Configuration Guide, 2009. Unlike IPSec SAs, ISAKMP SAs are bidirectional and the same keys and algorithms protect inbound and outbound communications. The first phase measures the current maturity of required controls in the environment using the Capability Maturity Model Integration (CMMI) model. What a best practice looks like for your business will depend on many factors, such as size, industry, location, and existing tools and policies. Security Services in Fieldbuses: At What Cost? Figure 16.39. To provide confidentiality, nodes may encrypt their contents using a random session key and a symmetric crypto-algorithm specially tailored for constrained environments. For example, IPsec is used to protect traffic in the core network as part of the NDS/IP framework (see Section 7.4). The main hardware components of a computer system are the CPU, primary and secondary memory, and input/output devices. If the user now moves to a different network (e.g. Our certifications and certificates affirm enterprise team members’ expertise and build stakeholder confidence in your organization. The data origin authentication service allows the receiver of the data to verify the identity of the claimed sender of the data. The enterprise in this example is a financial company, and their goal is to have an additional one million users within the next two years. 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 … Each layer has a different purpose and view. Traditionally, security architecture consists of some preventive, detective and corrective controls that are implemented to protect the enterprise infrastructure and applications. If for a given fieldbus public key cryptography solutions are too expensive, we can still design limited security schemes for fieldbuses at a cheaper price, i.e. 6 CMMI Institute, “CMMI Maturity Levels,” http://cmmiinstitute.com/capability-maturity-model-integration. It is a secure application development framework that equips applications with security capabilities for delivering secure Web and e-commerce applications. Mandatory IKE parameters are: Authentication method: Pre-Shared Key and X.509 Certificates. 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. The IPsec SAs are used for the IPsec protection of the data using ESP or AH. Evan Wheeler, in Security Risk Management, 2011. 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. Validate your expertise and experience. 1 ISACA, COBIT 5, USA, 2012, www.isaca.org/COBIT/Pages/COBIT-5-Framework-product-page.aspx 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. Eric Conrad, ... Joshua Feldman, in CISSP Study Guide (Second Edition), 2012. On other interfaces in EPS, however, it is primarily IKEv2 that is used. In transport mode ESP is used to protect the payload of an IP packet. Zhendong Ma, ... Paul Murdock, in Smart Grid Security, 2015. The SABSA methodology has six layers (five horizontals and one vertical). As a system of systems, the Smart Grid consists of software components that have varied security and assurance levels, and diverse origins and development processes. And on the other hand, public key cryptography requires complex algorithms, large key-sizes, and management of the public keys. ScienceDirect ® is a registered trademark of Elsevier B.V.

Carlisle Adams, in. 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. The work in [RAJ 08] presented a method to address handover issues between 3GPP networks and non-3GPP networks. It is not the intention and ambition of this chapter to provide a complete overview and tutorial on IPsec. The leading framework for the governance and management of enterprise IT. In a nutshell, DSS requires that your organization is … The fair question is always, “Where should the enterprise start?”. REST is an architectural style for building distributed systems based on hypermedia. Each layer has a different purpose and view. For example, on the SWu interface between UE and ePDG, and on the S2c interface between UE and PDN GW, IKEv2 is used. Affirm your employees’ expertise, elevate stakeholder confidence. TOGAF is a framework and a set of supporting tools for developing an enterprise architecture.4 The TOGAF architecture development cycle is great to use for any enterprise that is starting to create an enterprise security architecture. He started as a computer network and security professional and developed his knowledge around enterprise business, security architecture and IT governance. Then, in future instances, it sends previously collected requests to a new eNB when a UE would like to move to the target eNB. EPS makes use of both IKEv1 and IKEv2. The gateways must self-authenticate and choose session keys that will secure the traffic. In addition, an active attacker can grab the handover request messages sent from an old eNB to the new eNB. What are Data Security Standards (DSS)? Examples of Data Architecture standards to aid in standards identification..These are not proposals but rather a list of standards in use in other Organizations. Start your career among a talented community of professionals. Confidentiality is the service that protects the traffic from being read by unauthorized parties. Similar to other frameworks, TOGAF starts with the business view and layer, followed by technology and information (figure 5).5. ISACA is, and will continue to be, ready to serve you. The initial steps of a simplified Agile approach to initiate an enterprise security architecture program are: It is that simple. Industry Standard Architecture is the 16-bit internal bus of IBM PC/AT and similar computers based on the Intel 80286 and its immediate successors during the 1980s. (On this high level, the procedure is similar for IKEv1 and IKEv2.) This phase is protected by the IKE SA established in phase 1. The IPsec SA for ESP has been set up using IKEv2 (see Section 10.10 for more details). Many information security professionals with a traditional mind-set view security architecture as nothing more than having security policies, controls, tools and monitoring. For 50 years and counting, ISACA® has been helping information systems governance, control, risk, security, audit/assurance and business and cybersecurity professionals, and enterprises succeed. After the program is developed and controls are being implemented, the second phase of maturity management begins. This can be done manually by simply configuring both parties with the required parameters. The establishment of an SA using IKEv1 or IKEv2 occurs in two phases. 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. 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. The information security architecture represents the portion of the enterprise architecture that specifically addresses information system resilience and provides architectural information for the implementation of capabilities to meet security requirements. Phase 2: IPSec SAs are negotiated after the secure ISAKMP channel is established. Also, mutual authentication of the two parties takes place during phase 1. As you can see in the diagram above, a standard data-centric architecture has five parts: Software system: The system developed using the data-centric architecture model. Take advantage of our CSX® cybersecurity certificates to prove your cybersecurity know-how and the specific skills you need for many technical roles. Each IPsec SA is uniquely identified by a Security Parameter Index (SPI), together with the destination IP address and security protocol (AH or ESP; see below). 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. The set of security services provided by IPsec include: By access control we mean the service to prevent unauthorized use of a resource such as a particular server or a particular network. 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. The integrity service protects the data against non-authorized modifications, insertions or deletions. 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. The contextual layer is at the top and includes business requirements and goals. If used together, ESP is typically used for confidentiality and AH for integrity protection. 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. Example of IP Packet Protected Using ESP in Tunnel Mode. This Quick Start sets up an AWS Cloud environment that provides a standardized architecture for Payment Card Industry (PCI) Data Security Standard (DSS) compliance. Peer-reviewed articles on a variety of industry topics. application, data, infrastructure architecture (hardware, systems, and networks), and security. The secure channel is called ISAKMP Security Association. IP Packet (Data) Protected by ESP. Data-centric architecture. Get an early start on your career journey as an ISACA student member. Agencies can address risk management considerations at the mission and business tier by [34]: Developing an information security segment architecture linked to the strategic goals and objectives, well-defined mission and business functions, and associated processes. It is important for all security professionals to understand business objectives and try to support them by implementing proper controls that can be simply justified for stakeholders and linked to the business risk. Regardless of the methodology or framework used, enterprise security architecture in any enterprise must be defined based on the available risk to that enterprise. As will be seen below, the IKE protocol can be used to establish and maintain IPsec SAs. 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. This maturity can be identified for a range of controls. Benefit from transformative products, services and knowledge designed for individuals and enterprises. 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. 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. source and destination addresses, message length, or frequency of packet lengths. COBIT principles and enablers provide best practices and guidance on business alignment, maximum delivery and benefits. REST is independent of any underlying protocol and is not necessarily tied to HTTP. Even though IKEv1 has been replaced by IKEv2, IKEv1 is still in operational use. For the latter, the delay of handover has been reduced without compromising the security level. Rassoul Ghaznavi-Zadeh, CISM, COBIT Foundation, SABSA, TOGAF 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. IKE provides authenticated secure key exchange with perfect forward secrecy (based on the Diffie-Hellman protocol) and mutual peer authentication using public keys or shared secrets. This is done by creating the architecture view and goals, completing a gap analysis, defining the projects, and implementing and monitoring the projects until completion and start over (figure 5). The enterprise frameworks SABSA, COBIT and TOGAF guarantee the alignment of defined architecture with business goals and objectives. 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. The verification of the hash code is designed to detect intentional and unauthorized modifications of the data, as well as accidental modifications. See Figures 16.38 and 16.39 for illustrations of ESP- and AH-protected packets. 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. In phase 1 an IKE SA is generated that is used to protect the key exchange traffic. Figure 16.41. Miguel Leόn Chávez, Francisco Rodríguez Henríquez, in Fieldbus Systems and Their Applications 2005, 2006. 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. 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. Depending on the architecture, it might have more or fewer controls. (One could view IKE as the creator of SAs and IPsec as the user of SAs.) A security model is a statement that out-lines the requirements necessary to properly support and implement a certain security policy. IKE parameters are negotiated as a unit and are termed a protection suite. Moreover, some of the security services defined by ISO are probably not very likely to be useful on the context of some fieldbuses. Implementing security architecture is often a confusing process in enterprises. It is used to assist in replay protection. Originally referred to as the PC bus or AT bus, it was also termed I/O Channel by IBM. Beyond training and certification, ISACA’s CMMI® models and platforms offer risk-focused programs for enterprise and product assessment and improvement. Enterprise frameworks, such as Sherwood Applied Business Security Architecture (SABSA), COBIT and The Open Group Architecture Framework (TOGAF), can help achieve this goal of aligning security needs with business needs. The MOBIKE protocol extends IKEv2 with possibilities to dynamically update the IP address of the IKE SAs and IPsec SAs. To provide security of handovers, the work in [ZHE 05] proposed a hybrid AKA scheme that supported global mobility. See Figure 16.41 for an illustration of a UDP packet that is protected using ESP in tunnel mode. The Internet Key Exchange (IKE) is implemented on top of UDP, port 500. IKEv1 has subsequently been replaced by IKEv2, which is an evolution of IKEv1/ISAKMP. Detection and rejection of replays is a form of partial sequence integrity, where the receiver can detect if a packet has been duplicated. Define component architecture and map with physical architecture: Security standards (e.g., US National Institute of Standards and Technology [NIST], ISO), Security products and tools (e.g., antivirus [AV], virtual private network [VPN], firewall, wireless security, vulnerability scanner), Web services security (e.g., HTTP/HTTPS protocol, application program interface [API], web application firewall [WAF]), Not having a proper disaster recovery plan for applications (this is linked to the availability attribute), Vulnerability in applications (this is linked to the privacy and accuracy attributes), Lack of segregation of duties (SoD) (this is linked to the privacy attribute), Not Payment Card Industry Data Security Standard (PCI DSS) compliant (this is linked to the regulated attribute), Build a disaster recovery environment for the applications (included in COBIT DSS04 processes), Implement vulnerability management program and application firewalls (included in COBIT DSS05 processes), Implement public key infrastructure (PKI) and encryption controls (included in COBIT DSS05 processes), Implement SoD for the areas needed (included in COBIT DSS05 processes), Application security platform (web application firewall [WAF], SIEM, advanced persistent threat [APT] security), Data security platform (encryption, email, database activity monitoring [DAM], data loss prevention [DLP]), Access management (identity management [IDM], single sign-on [SSO]), Host security (AV, host intrusion prevention system [HIPS], patch management, configuration and vulnerability management), Mobile security (bring your own device [BYOD], mobile device management [MDM], network access control [NAC]), Authentication (authentication, authorization, and accounting [AAA], two factor, privileged identity management [PIM]).
