data security architecture designed using an industry standard


ISAKMP is, however, distinct from the actual key exchange protocols in order to cleanly separate the details of security association management (and key management) from the details of key exchange. These leaders in their fields share our commitment to pass on the benefits of their years of real-world experience and enthusiasm for helping fellow professionals realize the positive potential of technology and mitigate its risk. Tunnel mode is typically used to protect all IP traffic between security gateways or in VPN connections where a UE connects to a secure network via an unsecure access. Gain a competitive edge as an active informed professional in information systems, cybersecurity and business. SABSA is a business-driven security framework for enterprises that is based on risk and opportunities associated with it. 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). To provide security of handovers, the work in [ZHE 05] proposed a hybrid AKA scheme that supported global mobility. 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 … ISACA resources are curated, written and reviewed by experts—most often, our members and ISACA certification holders. Integrity and non-repudiation can be obtained by signing/verifying all the messages transmitted between a particular slave node and the master node. Other optional parameters such as SA lifetime can also be part of the protection suite. 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. The Sequence number contains a counter that increases for each packet sent. 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. IP Packet (Data) Protected by ESP. 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. Figure 1 shows the six layers of this framework. LTE security architecture benefits from key freshness techniques used in the handover process to prevent security threats from malicious eNBs. 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. 1 ISACA, COBIT 5, USA, 2012, www.isaca.org/COBIT/Pages/COBIT-5-Framework-product-page.aspx 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 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. The world has changed; security is not the same beast as before. 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. 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. In addition, an active attacker can grab the handover request messages sent from an old eNB to the new eNB. Start your career among a talented community of professionals. Today’s risk factors and threats are not the same, nor as simple as they used to be. It is not the intention and ambition of this chapter to provide a complete overview and tutorial on IPsec. data security requirements. The IPsec security architecture is defined in IETF RFC 4301. Incorporating an information security architecture that implements architectural information security requirements within and across information systems. 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. In a nutshell, DSS requires that your organization is … A well-designed and executed data security policy that ensures both data security and data privacy. The second-best source for industry standards was the CCS CSC, which covered 48 of the 72 FTC's expected reasonable data security practices. See Figure 16.41 for an illustration of a UDP packet that is protected using ESP in tunnel mode. Hover over the various areas of the graphic and click inside the Box for additional information associated with the system elements. CDSA was originally developed by Intel Architecture Lab (IAL). Examples are the authentication algorithms, encryption algorithms, keys, lifetimes for each SA (by seconds and bytes), and modes to use. 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. 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). For example, IPsec is used to protect traffic in the core network as part of the NDS/IP framework (see Section 7.4). In agencies with collaborative working relationships between enterprise architecture and information security programs (both of which commonly reside within the office of the chief information officer), integrating enterprise and security architectures may present little difficulty, but agencies without such close relationships may experience significant challenges harmonizing EA and security architecture perspectives. See Figure 16.40 for an illustration of a UDP packet that is protected using ESP in transport mode. IP Packet (Data) Protected by AH. Previous versions of ESP and AH are defined in IETF RFC 2406 and 2402 respectively. Regardless of the methodology or framework used, enterprise security architecture in any enterprise must be defined based on the available risk to that enterprise. 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. We are all of you! Figure 8 shows an example of a maturity dashboard for security architecture. IPsec is a very wide topic and many books have been written on this subject. 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. Quick Mode uses three messages, two for proposal parameters and a third to acquit the choice. Transport mode is often used between two endpoints to protect the traffic corresponding to a certain application. 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. Like any other framework, the enterprise security architecture life cycle needs to be managed properly. 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 verification of the hash code is designed to detect intentional and unauthorized modifications of the data, as well as accidental modifications. REST is an architectural style for building distributed systems based on hypermedia. 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. 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. The primary difference here is that, for existing systems, applications, or environments, active vulnerability assessments can be performed to educate the risk exposure calculations. 3 Op cit, ISACA 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]). 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. For untrusted non-3GPP networks, the authors proposed a pre-authentication approach. We use cookies to help provide and enhance our service and tailor content and ads. In the next section we give an overview of basic IPsec concepts. Audit Programs, Publications and Whitepapers. Take advantage of our CSX® cybersecurity certificates to prove your cybersecurity know-how and the specific skills you need for many technical roles. Similar to other frameworks, TOGAF starts with the business view and layer, followed by technology and information (figure 5).5. The main hardware components of a computer system are the CPU, primary and secondary memory, and input/output devices. Data security can be applied using a range of techniques and technologies, including administrative controls, physical security, logical controls, organizational standards, and other safeguarding techniques that limit access to 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. implement industry standard mobile security controls, reducing long-term costs and decreasing the risk of vendor lock-in ; 2. Our certifications and certificates affirm enterprise team members’ expertise and build stakeholder confidence in your organization. The integrity service protects the data against non-authorized modifications, insertions or deletions. 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. Defining the appropriate architectural information security requirements based on the organization’s risk management strategy. When IKEv1 is used, authentication can be based on either shared secrets or certificates by using a public key infrastructure (PKI). The contextual layer is at the top and includes business requirements and goals. 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. 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. See Figures 16.38 and 16.39 for illustrations of ESP- and AH-protected packets. Enterprise Architecture is still an emerging field. The SA database that contains parameters associated with each active SA. After that we discuss the Internet Key Exchange (IKE) protocol used for authentication and establishing IPsec Security Associations (SAs). A sound security architecture and the implementing technologies that have been discussed in previous chapters address only part of the challenge. The work in [RAJ 08] presented a method to address handover issues between 3GPP networks and non-3GPP networks. Consequently, the two peers generate a new Diffie-Hellman key pair. 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. (One could view IKE as the creator of SAs and IPsec as the user of SAs.) ISACA® offers training solutions customizable for every area of information systems and cybersecurity, every experience level and every style of learning. For you to successfully use the IPSec protocol, two gateway systems must negotiate the algorithms used for authentication and encryption. 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. 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. To provide confidentiality, nodes may encrypt their contents using a random session key and a symmetric crypto-algorithm specially tailored for constrained environments. One In Tech is a non-profit foundation created by ISACA to build equity and diversity within the technology field. 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. This includes messages, files, meetings, and other content. Gateway to data systems — data transmission from a gateway to the appropriate data system. For more details on S2c and SWu, see Sections 15.5.1 and 15.10.1Section 15.5.1Section 15.10.1 respectively. 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. Andrew Hay, ... Warren Verbanec, in Nokia Firewall, VPN, and IPSO Configuration Guide, 2009. 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. 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. A new IKEv2 authentication and IPsec SA establishment have to be performed. 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. Figure 16.38. ISACA membership offers these and many more ways to help you all career long. However, it does not detect if the packets have been duplicated (replayed) or reordered. This must be a top-down approach—start by looking at the business goals, objectives and vision. 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. On the road to ensuring enterprise success, your best first steps are to explore our solutions and schedule a conversation with an ISACA Enterprise Solutions specialist. 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. 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. The non-repudiation service prevents an entity from denying previous commitments or actions. 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. SABSA does not offer any specific control and relies on others, such as the International Organization for Standardization (ISO) or COBIT processes. On other interfaces in EPS, however, it is primarily IKEv2 that is used. 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. Figure 16.39. 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. 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. 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. 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. 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. The secure channel is called ISAKMP Security Association. 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 SABSA methodology has six layers (five horizontals and one vertical). It is purely a methodology to assure business alignment. Security Architecture and Design: The design and architecture of security services, which facilitate business risk exposure objectives. The gateways must self-authenticate and choose session keys that will secure the traffic. Phase 1: To safely set an IPSec SA, the two peers first establish a secure channel, which is an encrypted and authenticated connection. Allocating management, operational, and technical security controls to information systems and environments of operation as defined by the information security architecture. 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. Stephen D. Gantz, Daniel R. Philpott, in FISMA and the Risk Management Framework, 2013. Applying those principles to any architecture ensures business support, alignment and process optimization.3. 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. Connect with new tools, techniques, insights and fellow professionals around the world. Data security is a set of standards and technologies that protect data from intentional or accidental destruction, modification or disclosure. 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. 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. In this case the UE would have to negotiate a new IKE SA and IPsec SA, which may take a long time and result in service interruption. 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. 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 new eNB will retrieve old NCC value and send back to the UE. Likewise our COBIT® certificates show your understanding and ability to implement the leading global framework for enterprise governance of information and technology (EGIT). 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.
