While almost every federal agency can be expected to have an enterprise architecture—in most cases reflecting a common architecture framework such as the Federal Enterprise Architecture Framework (FEAF) or Department of Defense Architecture Framework (DoDAF)—there is much greater variation among agencies in the existence and structure of formally documented security architectures. ISACA® offers training solutions customizable for every area of information systems and cybersecurity, every experience level and every style of learning. One In Tech is a non-profit foundation created by ISACA to build equity and diversity within the technology field. Allocating management, operational, and technical security controls to information systems and environments of operation as defined by the information security architecture. Get in the know about all things information systems and cybersecurity. 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. 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. Evan Wheeler, in Security Risk Management, 2011. The non-repudiation service prevents an entity from denying previous commitments or actions. What a best practice looks like for your business will depend on many factors, such as size, industry, location, and existing tools and policies. Although the previous limited security schemes have a cheaper price, some fieldbuses may not be able to afford them. NIST considers information security architecture to be an integrated part of enterprise architecture, but conventional security architecture and control frameworks such as ISO 27001, NIST Special Publication 800-53, and the Sherwood Applied Business Security Architecture (SABSA) have structures that do not align directly to the layers typical in enterprise architectures. See Figures 16.38 and 16.39 for illustrations of ESP- and AH-protected packets. ISAKMP, IKEv1, and their use with IPsec are defined in IETF RFC 2407, RFC 2408, and RFC 2409. In order to communicate using IPsec, the two parties need to establish the required IPsec SAs. After the program is developed and controls are being implemented, the second phase of maturity management begins. Control tables: A set of tables that define the action items the … For example, on the SWu interface between UE and ePDG, and on the S2c interface between UE and PDN GW, IKEv2 is used. This includes messages, files, meetings, and other content. The work in [RAJ 08] presented a method to address handover issues between 3GPP networks and non-3GPP networks. The hash functions accept a variable-size message as input and produce a fixed-size code, called the hash code or message digest. 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 4 The Open Group, “Welcome to TOGAF 9.1, an Open Group Standard, http://pubs.opengroup.org/architecture/togaf9-doc/arch/ 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. to a different WLAN hotspot) and receives a new IP address from the new network, it would not be possible to continue using the old IPsec SA. The Sequence number contains a counter that increases for each packet sent. PCI DSS is a set of regulations created by 5 major payment card brands: Visa, MasterCard, American Express, Discover, and JCB. Contribute to advancing the IS/IT profession as an ISACA member. New emerging technologies and possibilities, e.g., the Internet of Things, change a lot about how companies operate, what their focus is and their goals. It is purely a methodology to assure business alignment. Data is usually one of several architecture domains that form the pillars of an enterprise architecture or solution architecture. IPsec is also used on the SWu interface to protect user-plane traffic between the UE and the ePDG, as well on the S2c interface to protect DSMIPv6 signaling between the UE and the PDN GW. For instance, data confidentiality can be achieved by using some lightweight cryptographic stream cipher, such as RC4 or A5/1 GSM, or even a reduced version of traditional symmetric algorithms such as DES or AES, which can be obtained by reducing the size of the encryption key or by limiting the standard number of rounds used during the encryption/decryption processes (16 in the case of DES and 10 for AES). Has been an IT security consultant since 1999. IPsec is a very wide topic and many books have been written on this subject. However, in many scenarios a dynamic mechanism for authentication, key generation, and IPsec SA generation is needed. As a result, the scheme achieves mutual authentication along with non-repudiation. 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. The standards help create mechanisms by which the policies are enacted in order to avoid risks, identify … 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. The receiver computes the integrity check value for the received packet and compares it with the one received in the ESP or AH packet. Data-centric architecture. The initial steps of a simplified Agile approach to initiate an enterprise security architecture program are: It is that simple. Identifying where effective risk response is a critical element in the success of organizational mission and business functions. It defines the procedures and packet formats for authentication and SA management. We serve over 145,000 members and enterprises in over 188 countries and awarded over 200,000 globally recognized certifications. 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. The Main Mode negotiation uses six messages, in a triple two-way exchange. 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. 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). Regardless of the methodology or framework used, enterprise security architecture in any enterprise must be defined based on the available risk to that enterprise. 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. 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. IP Packet (Data) Protected by AH. Data origin authentication and connection-less integrity are typically used together. Figure 8 shows an example of a maturity dashboard for security architecture. When IKEv1 is used, authentication can be based on either shared secrets or certificates by using a public key infrastructure (PKI). To provide security of handovers, the work in [ZHE 05] proposed a hybrid AKA scheme that supported global mobility. Figure 16.38. When you want guidance, insight, tools and more, you’ll find them in the resources ISACA® puts at your disposal. EPS makes use of both IKEv1 and IKEv2. Build your team’s know-how and skills with customized training. IP Packet (Data) Protected by ESP. Originally referred to as the PC bus or AT bus, it was also termed I/O Channel by IBM. On other interfaces in EPS, however, it is primarily IKEv2 that is used. Confidentiality is the service that protects the traffic from being read by unauthorized parties. The scheme uses a security context transfer mechanism to achieve its goal for trusted non-3GPP networks. For more details on S2c and SWu, see Sections 15.5.1 and 15.10.1Section 15.5.1Section 15.10.1 respectively. 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. As will be seen below, the IKE protocol can be used to establish and maintain IPsec SAs. A modern data architecture (MDA) must support the next generation cognitive enterprise which is characterized by the ability to fully exploit data using exponential technologies like pervasive artificial intelligence (AI), automation, Internet of Things (IoT) and blockchain. Define a program to design and implement those controls: Define conceptual architecture for business risk: Governance, policy and domain architecture. The gateways must self-authenticate and choose session keys that will secure the traffic. SABSA is a business-driven security framework for enterprises that is based on risk and opportunities associated with it. ESP and AH are typically used separately but it is possible, although not common, to use them together. Gateway to data systems — data transmission from a gateway to the appropriate data system. 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 user traffic between the UE and the ePDG (i.e. 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. 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. 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 can be done manually by simply configuring both parties with the required parameters. There are in fact two versions of IKE: IKE version 1 (IKEv1) and IKE version 2 (IKEv2). 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). ESP can provide integrity and confidentiality while AH only provides integrity. It is not the intention and ambition of this chapter to provide a complete overview and tutorial on IPsec. Documenting risk management decisions at all levels of the enterprise architecture. COBIT principles and enablers provide best practices and guidance on business alignment, maximum delivery and benefits. Translating architectural information security requirements into specific security controls for information systems and environments of operation. Andrew Hay, ... Warren Verbanec, in Nokia Firewall, VPN, and IPSO Configuration Guide, 2009. Security Services in Fieldbuses: At What Cost? 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. 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. CDSA was adopted by the 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. Here are a few metrics that might work: 1. Figure 16.40. By continuing you agree to the use of cookies. 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 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. Particularly, non-repudiation seems to be not suitable for the centralized fieldbuses since the master node “gives permission to speak” to each slave node. The two peers agree on authentication and encryption methods, exchange keys, and verify the other's identity. 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. 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. The node may want to use a different interface in case the currently used interface suddenly stops working. 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 information security architecture seeks to ensure that information systems and their operating environments consistently and cost-effectively satisfy mission and business process-driven security requirements, consistent with the organizational risk management strategy and sound system and security engineering principles. One mode is defined for phase 2. Participate in ISACA chapter and online groups to gain new insight and expand your professional influence. Magnus Olsson, ... Catherine Mulligan, in EPC and 4G Packet Networks (Second Edition), 2013. data security requirements. If used together, ESP is typically used for confidentiality and AH for integrity protection. Moreover, some of the security services defined by ISO are probably not very likely to be useful on the context of some fieldbuses. The ISA term … Connect with new tools, techniques, insights and fellow professionals around the world. Each layer has a different purpose and view. 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. IKE parameters are negotiated as a unit and are termed a protection suite. For example, IPsec is used to protect traffic in the core network as part of the NDS/IP framework (see Section 7.4). 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. With “perfect forward secrecy” enabled, the default value in Nokia's configuration, a new Diffie-Hellman exchange must take place during Quick Mode. Phase 2: IPSec SAs are negotiated after the secure ISAKMP channel is established. He started as a computer network and security professional and developed his knowledge around enterprise business, security architecture and IT governance. Understanding these fundamental issues is critical for an information security professional. 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. To secure bidirectional communication between two hosts or two security gateways, you require two SAs—one in each direction. Figure 16.39. IKEv2 is defined in a single document, IETF RFC 4306, which thus replaces the three RFCs used for documenting IKEv1 and ISAKMP. 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. Start your career among a talented community of professionals. If one looks at these frameworks, the process is quite clear. In transport mode ESP is used to protect the payload of an IP packet. Figure 2 shows the COBIT 5 product family at a glance.2 COBIT Enablers are factors that, individually and collectively, influence whether something will work. Available 24/7 through white papers, publications, blog posts, podcasts, webinars, virtual summits, training and educational forums and more, ISACA resources. The IPsec SA for ESP has been set up using IKEv2 (see Section 10.10 for more details). The SABSA methodology has six layers (five horizontals and one vertical). 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). This must be a top-down approach—start by looking at the business goals, objectives and vision. The COBIT 5 product family has a lot of documents to choose from, and sometimes it is tough to know exactly where to look for specific information. 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. The latest version of PCI DSS (version 3.2) was released in April 2016 with the Council setting these requirements for any business that processes credit or debit card transactions. 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 leading framework for the governance and management of enterprise IT. Finally, there must be enough monitoring controls and key performance indicators (KPIs) in place to measure the maturity of the architecture over time. The secure channel is called ISAKMP Security Association. A well-designed and executed data security policy that ensures both data security and data privacy. 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]). It is a secure application development framework that equips applications with security capabilities for delivering secure Web and e-commerce applications. The life cycle of the security program can be managed using the TOGAF framework. The establishment of an SA using IKEv1 or IKEv2 occurs in two phases. 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 … Transport mode is often used between two endpoints to protect the traffic corresponding to a certain application. Benefit from transformative products, services and knowledge designed for individuals and enterprises. Mandatory IKE parameters are: Authentication method: Pre-Shared Key and X.509 Certificates. Every packet exchanged in phase 2 is authenticated and encrypted according to keys and algorithms selected in the previous phase. In 2000, Roy Fielding proposed Representational State Transfer (REST) as an architectural approach to designing web services. 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. After phase 2 is completed, the two parties can start to exchange traffic using EPS or AH. After the architecture and the goals are defined, the TOGAF framework can be used to create the projects and steps, and monitor the implementation of the security architecture to get it to where it should be. 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. implement industry standard mobile security controls, reducing long-term costs and decreasing the risk of vendor lock-in ; 2. Likewise our COBIT® certificates show your understanding and ability to implement the leading global framework for enterprise governance of information and technology (EGIT). 6 CMMI Institute, “CMMI Maturity Levels,” http://cmmiinstitute.com/capability-maturity-model-integration. The TOGAF framework is useful for defining the architecture goals, benefits and vision, and setting up and implementing projects to reach those goals. In tunnel mode, on the other hand, ESP and AH are used to protect a complete IP packet. Audit Programs, Publications and Whitepapers. 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. Companies enact a data security policy for the sole purpose of ensuring data privacy or the privacy of their consumers' information. Learn why ISACA in-person training—for you or your team—is in a class of its own. The messages containing the identity information are not authenticated or encrypted. However, most common REST implementations use HTTP as the application protocol, and this guide focuses on designing REST APIs for HTTP. ISACA® membership offers you FREE or discounted access to new knowledge, tools and training. IKEv1 is based on the Internet Security Association and Key Management Protocol (ISAKMP) framework. A security model is a statement that out-lines the requirements necessary to properly support and implement a certain security policy. Beyond training and certification, ISACA’s CMMI® models and platforms offer risk-focused programs for enterprise and product assessment and improvement. An SA is the relation between the two entities, defining how they are going to communicate using IPsec. Limited traffic flow confidentiality is a service whereby IPsec can be used to protect some information about the characteristics of the traffic flow, e.g. fast security algorithms requiring a small amount of memory. RFC 4301 is an update of the previous IPsec security architecture specification found in IETF RFC 2401. To determine what protocol to use, you should analyze data traffic (frequency of burstiness and congestion, security requirements and how many parallel connections are needed). During communication, slave and master nodes may mutually authenticate each other with these keys using well known protocols. PCI DSS helps ensure that companies maintain a secure environment for storing, processing, and transmitting credit card information. This mode is called Quick Mode. Get an early start on your career journey as an ISACA student member. This is where Internet Key Exchange (IKE) comes into the picture. q Sharing of data greatly reduces data entry and maintenance efforts. Like any other framework, the enterprise security architecture life cycle needs to be managed properly. Integrity and non-repudiation can be obtained by signing/verifying all the messages transmitted between a particular slave node and the master node. The Data part of the ESP packet in Figure 16.38 now corresponds to a complete IP packet, including the IP header. Zhendong Ma, ... Paul Murdock, in Smart Grid Security, 2015. REST is an architectural style for building distributed systems based on hypermedia. SABSA does not offer any specific control and relies on others, such as the International Organization for Standardization (ISO) or COBIT processes. That can be accomplished by assigning to each slave node in the network a unique private key and a master node’s public key. A sound security architecture and the implementing technologies that have been discussed in previous chapters address only part of the challenge. To provide confidentiality, nodes may encrypt their contents using a random session key and a symmetric crypto-algorithm specially tailored for constrained environments. Incorporating an information security architecture that implements architectural information security requirements within and across information systems. Affirm your employees’ expertise, elevate stakeholder confidence. 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. Some enterprises are doing a better job with security architecture by adding directive controls, including policies and procedures. After that we discuss the Internet Key Exchange (IKE) protocol used for authentication and establishing IPsec Security Associations (SAs). For untrusted non-3GPP networks, the authors proposed a pre-authentication approach. Data security is a set of standards and technologies that protect data from intentional or accidental destruction, modification or disclosure. IKEv1 has subsequently been replaced by IKEv2, which is an evolution of IKEv1/ISAKMP. LTE security architecture benefits from key freshness techniques used in the handover process to prevent security threats from malicious eNBs. REST is independent of any underlying protocol and is not necessarily tied to HTTP. Traditionally, security architecture consists of some preventive, detective and corrective controls that are implemented to protect the enterprise infrastructure and applications. Building security into Smart Grid from the component to the system level requires appropriate methods and techniques to rigorously address many heterogeneous security issues in all phases of the software and system development lifecycle. 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®. The IPsec security architecture is defined in IETF RFC 4301. A group of conductors called a bus interconnects these computer elements connected to the bus. Depending on the architecture, it might have more or fewer controls. Unlike IPSec SAs, ISAKMP SAs are bidirectional and the same keys and algorithms protect inbound and outbound communications. 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. 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. 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.
