data security architecture designed using an industry standard

This can be done manually by simply configuring both parties with the required parameters. The language used … 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. Copyright © 2020 Elsevier B.V. or its licensors or contributors. If the user now moves to a different network (e.g. 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. We use cookies to help provide and enhance our service and tailor content and ads. The non-repudiation service prevents an entity from denying previous commitments or actions. The initial steps of a simplified Agile approach to initiate an enterprise security architecture program are: It is that simple. In addition, an active attacker can grab the handover request messages sent from an old eNB to the new eNB. 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 NDS/IP standard allows both IKEv1 and IKEv2 to be used (see Section 7.4). 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. Define physical architecture and map with conceptual architecture: Database security, practices and procedures. IPsec provides security services for both IPv4 and IPv6. The IPsec security architecture is defined in IETF RFC 4301. 3 Op cit, ISACA Here are a few metrics that might work: 1. 6 CMMI Institute, “CMMI Maturity Levels,” http://cmmiinstitute.com/capability-maturity-model-integration. PCI DSS is a set of regulations created by 5 major payment card brands: Visa, MasterCard, American Express, Discover, and JCB. IP Packet (Data) Protected by ESP. Defining the appropriate architectural information security requirements based on the organization’s risk management strategy. ISACA membership offers these and many more ways to help you all career long. These services are defined as follows: The authentication service verifies the supposed identity of a user or a system. This maturity can be identified for a range of controls. The enterprise frameworks SABSA, COBIT and TOGAF guarantee the alignment of defined architecture with business goals and objectives. IKE is used for authenticating the two parties and for dynamically negotiating, establishing, and maintaining SAs. To provide security of handovers, the work in [ZHE 05] proposed a hybrid AKA scheme that supported global mobility. 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 Main Mode negotiation uses six messages, in a triple two-way exchange. In this phase, the ratings are updated and the management team has visibility of the progress. Evan Wheeler, in Security Risk Management, 2011. Data-centric architecture. When IKEv1 is used, authentication can be based on either shared secrets or certificates by using a public key infrastructure (PKI). 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. 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. 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. 1 ISACA, COBIT 5, USA, 2012, www.isaca.org/COBIT/Pages/COBIT-5-Framework-product-page.aspx Some of the business required attributes are: All of the controls are automatically justified because they are directly associated with the business attributes. The work in [RAJ 08] presented a method to address handover issues between 3GPP networks and non-3GPP networks. With “perfect forward secrecy” enabled, the default value in Nokia's configuration, a new Diffie-Hellman exchange must take place during Quick Mode. 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. As will be seen below, the IKE protocol can be used to establish and maintain IPsec SAs. Enterprise Architecture is still an emerging field. 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). Understanding these fundamental issues is critical for an information security professional. 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. 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. We serve over 145,000 members and enterprises in over 188 countries and awarded over 200,000 globally recognized certifications. It is a secure application development framework that equips applications with security capabilities for delivering secure Web and e-commerce applications. However, in many scenarios a dynamic mechanism for authentication, key generation, and IPsec SA generation is needed. 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. 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. The SA database that contains parameters associated with each active SA. Examples are the authentication algorithms, encryption algorithms, keys, lifetimes for each SA (by seconds and bytes), and modes to use. Regardless of the methodology or framework used, enterprise security architecture in any enterprise must be defined based on the available risk to that enterprise. 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. Get in the know about all things information systems and cybersecurity. EPS makes use of both IKEv1 and IKEv2. 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. IP Packet (Data) Protected by AH. Distributed denial of service (DDoS), firewall, intrusion prevention system (IPS), VPN, web, email, wireless, DLP, etc. 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. Data security is a set of standards and technologies that protect data from intentional or accidental destruction, modification or disclosure. We are all of you! A security model is a statement that out-lines the requirements necessary to properly support and implement a certain security policy. One mode is defined for phase 2. More certificates are in development. 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. The SPI can be seen as an index to a Security Associations database maintained by the IPsec nodes and containing all SAs. 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. Incorporating an information security architecture that implements architectural information security requirements within and across information systems. For you to successfully use the IPSec protocol, two gateway systems must negotiate the algorithms used for authentication and encryption. The second-best source for industry standards was the CCS CSC, which covered 48 of the 72 FTC's expected reasonable data security practices. 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. Each layer has a different purpose and view. 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. 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. The gateways must self-authenticate and choose session keys that will secure the traffic. For example, IPsec is used to protect traffic in the core network as part of the NDS/IP framework (see Section 7.4). IKE parameters are negotiated as a unit and are termed a protection suite. MOBIKE is defined in IETF RFC 4555. For example, on the SWu interface between UE and ePDG, and on the S2c interface between UE and PDN GW, IKEv2 is used. Figure 16.41. It is not the intention and ambition of this chapter to provide a complete overview and tutorial on IPsec. REST is independent of any underlying protocol and is not necessarily tied to HTTP. The fields in the ESP and AH headers are briefly described below. The TOGAF framework is useful for defining the architecture goals, benefits and vision, and setting up and implementing projects to reach those goals. Originally referred to as the PC bus or AT bus, it was also termed I/O Channel by IBM. 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 life cycle of the security program can be managed using the TOGAF framework. 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. 5 The Open Group, “TOGAF 9.1 Architecture Development Cycle,” http://pubs.opengroup.org/architecture/togaf9-doc/arch/chap05.html 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. This mode is called Quick Mode. 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). IKEv2 is defined in a single document, IETF RFC 4306, which thus replaces the three RFCs used for documenting IKEv1 and ISAKMP. Contribute to advancing the IS/IT profession as an ISACA member. Security Architecture and Design: The design and architecture of security services, which facilitate business risk exposure objectives. The secure channel is called ISAKMP Security Association. The one method to complete phase 1 is Main Mode. 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. 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). q Sharing of data greatly reduces data entry and maintenance efforts. One example is a multi-homing node with multiple interfaces and IP addresses. The hash functions accept a variable-size message as input and produce a fixed-size code, called the hash code or message digest. 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. Figure 1 shows the six layers of this framework. A well-designed and executed data security policy that ensures both data security and data privacy. 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. Miguel Leόn Chávez, Francisco Rodríguez Henríquez, in Fieldbus Systems and Their Applications 2005, 2006. Meet some of the members around the world who make ISACA, well, ISACA. The Sequence number contains a counter that increases for each packet sent. Has been an IT security consultant since 1999. 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. 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. 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. Although the previous limited security schemes have a cheaper price, some fieldbuses may not be able to afford them. Unlike IPSec SAs, ISAKMP SAs are bidirectional and the same keys and algorithms protect inbound and outbound communications. LTE security architecture benefits from key freshness techniques used in the handover process to prevent security threats from malicious eNBs. In the base IKEv2 protocol, it is not possible to change these IP addresses after the IKE SA has been created. 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.

What a best practice looks like for your business will depend on many factors, such as size, industry, location, and existing tools and policies. 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 MOBIKE protocol extends IKEv2 with possibilities to dynamically update the IP address of the IKE SAs and IPsec SAs. (One could view IKE as the creator of SAs and IPsec as the user of SAs.) Confidentiality is the service that protects the traffic from being read by unauthorized parties. The SABSA methodology has six layers (five horizontals and one vertical). As an ISACA member, you have access to a network of dynamic information systems professionals near at hand through our more than 200 local chapters, and around the world through our over 145,000-strong global membership community. 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 confidentiality service protects the data against non-authorized revelations. 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. The SABSA methodology has six layers (five horizontals and one vertical). SABSA layers and framework create and define a top-down architecture for every requirement, control and process available in COBIT. Allocating management, operational, and technical security controls to information systems and environments of operation as defined by the information security architecture. There are, however, scenarios where the IP addresses may change. And on the other hand, public key cryptography requires complex algorithms, large key-sizes, and management of the public keys. Our community of professionals is committed to lifetime learning, career progression and sharing expertise for the benefit of individuals and organizations around the globe. To secure bidirectional communication between two hosts or two security gateways, you require two SAs—one in each direction. 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. 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. Implementation: Security services and processes are implemented, operated and controlled. It is important to update the business attributes and risk constantly, and define and implement the appropriate controls. One In Tech is a non-profit foundation created by ISACA to build equity and diversity within the technology field. In a nutshell, DSS requires that your organization is … 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]). Define a program to design and implement those controls: Define conceptual architecture for business risk: Governance, policy and domain architecture. 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. Traditionally, security architecture consists of some preventive, detective and corrective controls that are implemented to protect the enterprise infrastructure and applications. (On this high level, the procedure is similar for IKEv1 and IKEv2.) 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 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. IPsec is a very wide topic and many books have been written on this subject. Peer-reviewed articles on a variety of industry topics. 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. Hamidreza Ghafghazi, ... Carlisle Adams, in Wireless Public Safety Networks 2, 2016. The first phase measures the current maturity of required controls in the environment using the Capability Maturity Model Integration (CMMI) model. The new eNB will retrieve old NCC value and send back to the UE. The second layer is the conceptual layer, which is the architecture view. IKEv1 is based on the Internet Security Association and Key Management Protocol (ISAKMP) framework. The user traffic between the UE and the ePDG (i.e. The scheme uses a security context transfer mechanism to achieve its goal for trusted non-3GPP networks. For untrusted non-3GPP networks, the authors proposed a pre-authentication approach. Like any other framework, the enterprise security architecture life cycle needs to be managed properly. 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. However, strong public key cryptography is in general an expensive fancy solution for fieldbuses because, on one hand, most of the field devices have limited capacities, such as processor speed and memory. Even though IKEv1 has been replaced by IKEv2, IKEv1 is still in operational use. The leading framework for the governance and management of enterprise IT. 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 the next section we give an overview of basic IPsec concepts. In tunnel mode, on the other hand, ESP and AH are used to protect a complete IP packet. The standards help create mechanisms by which the policies are enacted in order to avoid risks, identify … on the SWu interface) is protected using ESP in tunnel mode. Then, in future instances, it sends previously collected requests to a new eNB when a UE would like to move to the target eNB. The world has changed; security is not the same beast as before. 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 establishment of an SA using IKEv1 or IKEv2 occurs in two phases. Some enterprises are doing a better job with security architecture by adding directive controls, including policies and procedures. CDSA was adopted by the All the security services defined by ISO can be achieved in a centralized fieldbus by using public key cryptography. Detection and rejection of replays is a form of partial sequence integrity, where the receiver can detect if a packet has been duplicated. REST is an architectural style for building distributed systems based on hypermedia. PCI DSS helps ensure that companies maintain a secure environment for storing, processing, and transmitting credit card information. implement industry standard mobile security controls, reducing long-term costs and decreasing the risk of vendor lock-in ; 2. 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. ISAKMP typically uses IKEv1 for key exchange, but could be used with other key exchange protocols. 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. What are Data Security Standards (DSS)? data security requirements. A sound security architecture and the implementing technologies that have been discussed in previous chapters address only part of the challenge. The verification of the hash code is designed to detect intentional and unauthorized modifications of the data, as well as accidental modifications. 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. ISAKMP is a framework for negotiating, establishing, and maintaining SAs. 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. Example of IP Packet Protected Using ESP in Tunnel Mode. Build your team’s know-how and skills with customized training. ISACA® is fully tooled and ready to raise your personal or enterprise knowledge and skills base. For the latter, the delay of handover has been reduced without compromising the security level. 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). 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. 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). 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 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). Stephen D. Gantz, Daniel R. Philpott, in FISMA and the Risk Management Framework, 2013. In phase 1 an IKE SA is generated that is used to protect the key exchange traffic.
