    Introduction With an increase in information security professional certifications as well as institutions offering them, it could be quite overwhelming to recognize the accurate certification without sufficient information. Here, we would be offering an overview of the CISM certification, answering various questions that candidates might have right information before taking the exam about getting accredited and the career paths are going to be associated with it. Also, the study process of this certification, wouldn’t be considered that much easy, unless you opt for the CISM Certification training programs offered at the SPOTO Club. What Is the CISM Certification? The Certified Information Security Manager certification is an Information Security credential that is offered by ISACA and spotlighted on teaching the pertinent administrative skills connected to IT security. The CISM certification is proposed for professionals who would be particularly willing to focus on the supervisory aspect of information security, without unavoidably plunging into the complex inner workings of dissimilar information security perceptions. What Experience Do You Need? To attain eligibility for the certification, candidates need to satisfy a couple of requirements as outlined below. The candidates must:    Register, sit and exceed a 200-question examination. This is an obligation intended at determining the skill and knowledge set of course takers. Candidates must be familiar with computer networks and some basics of computer security.    Show substantiation of preceding work experience. Candidates need to have five years of preceding professional employment experience in information security, with three years as a security manager in at slightest three of the four main training areas. Eligibility is only valid when the reported experience is current, being within ten years from the application, or five years from passing the exam.    Continuing with and completing the rest of the application. After completing the above requirements, candidates must remember that the completion of the rest of the application is necessary for eligibility. Topics which would be covered by the examination would include Information Risk Management and Compliance, Information Security Governance, Information Security Incident Management, and Information Security Program Development and Management. Is the CISM Exam Worth the Effort? The process of getting CISM accreditation is painstakingly long and often this question would linger in candidates’ minds now and then. To understand the reimbursement of the well-deserved CISM, a review of a few jobs would be in order. The following job titles would match the CISM credential: Information Security Manager The ISM is tasked with acquiring senior management commitment, performing strategic alignment, performing adequate risk management, assessing security metrics, guarantying value delivery, and guarantying adequate resource management. Chief Information Officer Risks are emerging every day, the ability to manage risk and security would also be budding as a mission significant issue for small and large production enterprises worldwide. CISM would be given that the business leaders with the ability to understand as well as eloquent a host of multifaceted and demanding security management issues that could considerably impact enterprise success. Information Risk Compliance Specialist The CISM would be concerned and largely supervise the building and implementation of programs, practices, and policies to make certain that organizations comply with industry and government authoritarian requirements. The CISM mediates with internal business units, officially permitted teams, and HR to augment awareness within the organization. Conclusion People who get CISM certified understand business and how to administer and become accustomed technology in their industries and organizations. They identify serious issues as well as tune company-specific practices to allow for the governance of information and related technologies. The CISM credential is, therefore considered to be highly desirable, due to its capability to application to governmental security requirements in an industry wide conventional fashion. Organizations willpower for a long time to come remain approachable to recognized holders of the CISM. Thus, if you are attracted towards the benefits of the CISM and wish to acquire it, you should check out the training courses offered at the SPOTO Club. You can also earn other ISACA Certifications such as CISM and CISSP (Certified Information Systems Security Professional) with SPOTO Club's 100% real exam dumps.

    Solution to the problem of local routing conflict Why is there a local routing conflict problem? Traditional overlay vpn A corresponding GRE tunnel is established on the PE for each VPN user, routing information is passed between the PE and the PE, and the P device in the public network does not know the routing information of the private network. The customer completely hands over the creation and maintenance of the VPN to the service provider, with better confidentiality and security. However, different VPN users cannot share the same address space. Even if they can share, the addresses between PE and CE, and the addresses between tunnels must not be the same, and a large number of ACLs and policy routes must be used. It is not feasible in practice. So there will be local routing conflicts. Solutions: The solution to the problem of local routing conflicts is mainly borrowed from the dedicated PE peer-to-peer VPN model. The dedicated router has a clear division of labor, and each PE only keeps its own VPN route. P only reserves public network routes. The current idea is to integrate the functions of all these devices on one PE. The specific operation is to divide different VRFs on the PE device. Each VRF can be regarded as a virtual router, as if it is a dedicated PE device. The virtual router includes the following elements: ■ An independent routing table, of course, also includes an independent address space; ■ A set of interfaces belonging to this VRF, the specific VRF is judged by which interface the data packet is received from; ■ A group of routing protocols only used for this VRF. For each PE, one or more VRFs can be maintained, while maintaining a public network routing table (also called a global routing table). Multiple VRF instances are separated and independent of each other. Compared with the complicated ACL configuration, the mechanism of multiple forwarding tables greatly simplifies the PE router to provide isolated support for each VPN routing information. What is the RT value? It is not difficult to achieve VRF local routing differentiation, but to resolve remote routing differentiation, it is necessary to use specific policy rules on the PE to coordinate the relationship between each VRF and the global routing table. This mainly refers to how the PE device distinguishes whether the received route belongs to the VPN route or the global route on the public network. The solution is to add a specific mark to the VPN route. Different marks indicate different routes, and the PE device uses this mark to determine which VRF the route should be written to. To solve the problem of labeling, we need to find a solution from the attributes of BGP. The routing attributes of the BGP protocol are very flexible and have excellent scalability. Recalling the various attributes of BGP, the characteristics of community attributes are most suitable for solving this problem. The community attribute is an optional transitive attribute, which is mainly used to simplify the execution of policies. The group attribute indicates that a destination is a member of some destination groups, and these destinations share one or more common characteristics. In other words, the community attribute is for specific routes, and the peer groups with similar functions are for peer routers, which does not apply here. So we can solve the problems we face by transforming the attributes of the group. The function of the modified group attribute is the same as before, but in order to distinguish it from the traditional group attribute, we give it a new name-RT. In this way, the PE device can distinguish the routes of different VRFs by adding the RT attribute to the specific route entry. The essence of RT is that each VRF expresses its own routing choices and preferences. It can be divided into two parts: Export Target and Import Target; the former indicates the attributes of the routes I sent, and the latter indicates which routes I am interested in. At the same time, the application of RT is relatively flexible. Each VRF Export Target and Import Target can be configured with multiple attributes, for example: I am interested in red or blue routes. When receiving, it is an "or" operation, and the routes of red, blue, and both colors will be accepted. This allows very flexible VPN access control. Below we illustrate the application of RT through an example analysis: As shown in the figure, each red company's site is associated with the red VRF on the PE router. PE configures a globally unique RT (RED) for each red VRF as its input and output target. The RT will not be assigned to any other VRF as their RT (such as the blue VRF), so as to ensure that the VPN of the red company contains only the routes in its own VPN. The specific steps are as follows: ■ Site-1: The route I sent is red, and I only receive the red route; ■ Site-2: The route I sent is red, and I only receive the red route; ■ Site-5: The route I sent is red, and I only receive the red route; ■ Site-3: The route I sent is blue, and I only receive the blue route; ■ Site-4: The route I sent is blue, and I only receive the blue route; ■ Site-6: The route I sent is blue, and I only receive the blue route. In this way, only Site-1, 2, and 5 have their own routes with each other, and the two realize mutual access. The same is true for Site-3, 4, and 6. At this time, we can call Site-1, 2, 5 as VPN-A, and Site3, 4, 6 as VPN-B. Below we make a summary of this part through a comparison between the dedicated PE method and the VRF method: Compared Routing Receive route Special PE method On the routers belonging to a specific VPN, use the community attribute of BGP to mark the routes of this VPN with special tags. And send the route to the P router Receive all routes on the P router and send them to specific VPN PE devices according to the community attribute in the route VPF method In a VPF, the RT export rules are used when advertising routes. Send directly to other PE equipment On the PE at the receiving end, receive all routes and check according to the RT import rules configured for each VPN. If it matches the RT attribute in the route, add the route to the corresponding VPN Conclusion In this article, <mpls vpn architecture-3> I will introduce the second problem of traditional VPNs-the problem of routing propagation in the network. Two identical routes are spread in the network. How to distinguish the receiver; if you want to know what the RD value is, be sure to check it out If you desire to pass the Cisco exams and looking for the most reliable and clear to understand the material so, now it is very easy for you to get it at SPOTO.

    People who would be sitting for the Certified Information Systems Security Professional otherwise known as the CISSP exam have to sign a form forbidding them from sharing about the content or nature of the CISSP exam. For this reason, people would be allocating little about the temperament of the CISSP exam. However, some few details would be quite obvious which would be discussed by the past candidates, instructors, and even exam composers. You should also acquire a good and reliable training provider like the SPOTO Club. The CISSP certification exam would be consisting of 250 questions, which a candidate would be required to answer in six hours. Nevertheless, 25 of these questions are considered to be tentative and only 225 questions account for the score of a candidate. The exam composers would be distributing randomly the investigational questions throughout the exam and also, a candidate couldn’t be recognizing a question that is considered to be investigational and one that is not. The questions on the exam would be carrying different weighting as well as adding up to 1000 points. Therefore, you wouldn’t be able to point out the exact number of questions you have to answer correctly to clear the exam. To clear the exam, candidates would be required to score about 700 points out of the 1000 points. To achieve 700 points, you would have responded most of the questions because you couldn’t point out the investigational questions, which could by no means earn you points. You clear the CISSP exam if you would be having a score of 70 percent. However, less than 8 percent of candidates who clear the exam would be able to achieve a score of more than 85 percent. The weighting of questions In the older CISSP exam, the average mark for each question would be used to be was.4. The least weighting was 2 and the most weighting was 6. For this reason, candidates are required to focus much on the weighting. They have to attempt all questions as well as manage time on management concepts too. Even if candidates would have tried to point out questions, which would be carried more marks than the others did, they wouldn’t be in a position to do so with certainty. Candidates would be sitting for the CISSP exam conventionally; you would be required an exam booklet, answer sheet over and above pencils. There would be no computer-based version of the exam. You are required to write all your answers on the answer sheet if you would be scoring marks for answering the questions. You might be writing on the booklet but you wouldn’t be able to achieve marks for what you have to inscribe on the booklet. Number of Questions per Domain The number of questions which would be derived from each domain differs. However, the exams are required to ask a minimum number of questions from each domain to harmonizing the exam. The least number of questions from a single domain is considered to be 14 questions, approximately 6 percent of all questions. The most number of questions derived from a single domain is considered to be about 32 questions, approximately 14 percent of all questions. Many questions would be likely to come from the top domains, which are mentioned about, information as well as security, telecommunication, and access control. Also, you would be required to wish to have a good and reliable training provider, such as the SPOTO Club’s CISSP Training Modules. It is considered to be your best bet of gaining the CISSP Credential in a single attempt.

    Multiprotocol Label Switching (MPLS) is a kind of IP (Internet Protocol) backbone network technology. MPLS introduces the concept of connection-oriented label switching on a connectionless IP network, and combines Layer 3 routing technology with Layer 2 switching technology to give full play to the flexibility of IP routing and the simplicity of Layer 2 switching. MPLS originated from IPv4 (Internet Protocol version 4), and its core technology can be extended to multiple network protocols, including IPv6 (Internet Protocol version 6), IPX (Internet Packet Exchange), and CLNP (Connectionless Network Protocol). "Multiprotocol" in MPLS refers to support for multiple network protocols. This shows that MPLS is not a service or application, it is actually a tunneling technology. This technology not only supports multiple high-level protocols and services, but also guarantees the security of information transmission to a certain extent. MPLS label forwarding table  Before forwarding the data packet, the MPLS network router generates the routing table RIB according to the routing protocol The router's hardware CEF will generate a FIB table for hardware forwarding (this table is similar to a routing table) Then the router will generate the label database LIB table through the LDP protocol, Then the LDP protocol will generate the label forwarding table LFIB based on the LIB table and the original FIB table The label forwarding table records information such as incoming labels, outgoing labels, operations performed on labels, and outgoing interfaces. In an MPLS network, packets are forwarded according to matching label forwarding entries. The LDP protocol is a label distribution protocol and must be used in conjunction with the IGP protocol. Only when the network is reachable can LDP neighbors be established. Ingress (R1) receives an unlabeled packet, determines the FEC to which the packet belongs and the corresponding label forwarding entry according to the destination address, and adds a label to the packet (202) And forward the labeled packet from the corresponding outgoing interface (F0 / 1) to the next-hop LSR (R2). Router 2 looks up the label forwarding entry corresponding to the incoming label according to the label (202) on the packet. Replace the original label with a new label (302) and forward the labeled packet to the next-hop LSR (R3) from the corresponding outgoing interface (F0 / 1). R3 finds the label forwarding entry corresponding to the incoming label according to the label (302) on the packet, and finds that it is a POP label, and the POp label is a pop-up action. We find that the label performs a label pop-up action in the penultimate hop of the mpls field R4 looks up the routing table and forwards the packet from the corresponding interface Forward the packet according to the IP header. What is the penultimate popup? IP lookup and label lookup: If the LSR receives an IP packet, it looks at the FIB table, then the LSR pushes the IP packet into a label header, labels it with 16, and then forwards it from the F0 / 0 interface. In CISCO, CEF switching is an IP forwarding mode used to mark packets, so CEF must be turned on on the router when MPLS is enabled. When a router receives a labeled message, it searches in the LFIB table. The relevant matching entries in the LFIB table will have the outbound action or label for the inbound label and the next hop information. If the router receives a labeled packet and the top label cannot be found in the local LFIB, then CISCO IOS will discard it What is the impact if the penultimate popup is not performed? The first search: after receiving the labeled packet, search the label forwarding table The second search: After popping the label in the packet, the next layer of label forwarding or IP forwarding Therefore, the Egress node should search the forwarding table twice before forwarding the packet: twice the label forwarding table or once the label forwarding table and once the routing forwarding table. This increases the processing pressure of the edge device Therefore, in order to reduce the burden on the egress node and improve the packet processing capability of the MPLS network, PHP can be used to pop the penultimate hop, and the label can be popped at the penultimate hop node. Egress implements the penultimate hop pop by assigning an empty label. The tag value of an empty tag is 3, and this value will not appear in the tag stack. When an LSR finds that the label advertised by the downstream LSR is an empty label, it will directly pop the label and forward the packet to the downstream LSR (ie Egress). After Egress receives the packet, it directly forwards to the next layer. about cisco certification lookup click there Summary of label processing actions Remove: The top label is removed. Packet forwarding relies on the remaining labels in the label stack or forwards them as unlabeled packets. exchange: The top label is removed, and a new label is used to replace the removed label. Add to: The top label is replaced (swapped) by a new label, and one or more labels are added above the replaced label. Unlabeled / unlabeled: The label stack is completely removed, and the packet is forwarded in an unlabeled manner. polymerization: The label stack is removed, and IP lookup is performed on the IP packet What is the difference between POP and Untag? POP POP will only pop the top-level label header. The packet forwarded by this action can be an IP packet or an MPLS label packet. Untag will remove all label headers and turn it into a pure IP packet. . The POP receives the empty label assigned to a specific prefix from the downstream. The value of this label is 3, then when the LSR sends data to the prefix to the downstream LSR, he will pop up the top-level label (POP) for forwarding , Note that this time only needs to check for this LSR Find the LFIB once, there is information about the next hop in the LFIB, so the top-level label is popped up and then handed over to the next hop instead of looking up the FIB table again (if the label is an IP packet). UNTAG All labels are popped up and then forwarded according to the next hop (find FIB table). There are three reasons for untags: No labels can be assigned downstream, MPLS is not enabled The downstream label was divided but could not be transmitted because the LDP Neighbor was not established The label assignment is incorrect. This situation occurs only when IGP is OSPF, because if the loopback port is used as the router-id of the ldp, And it is not 32-bit, OSPF will automatically publish with a 32-bit loopback address, which will cause label assignment errors.

    Three problems with traditional networks The scope of virtual machine migration is limited by the network architecture Due to the network attribute requirements of virtual machine migration, if it is migrated from one physical machine to another physical machine and requires uninterrupted service of the virtual machine, its IP address, MAC address and other parameter dimensions need to remain unchanged. Layer 2 network, and requires the network itself to have the redundancy and reliability of multipath and multilink. Virtual machine size is limited by network specifications In the large layer 2 network environment, the data flow needs to pass through explicit network addressing to ensure that it reaches the destination accurately. Therefore, the size of the layer 2 address table entry (MAC address table) of the network device has become the virtual machine in the cloud computing environment The upper limit of the scale. Network isolation / separation capability limitation The current mainstream network isolation technology is VLAN (or VPN), and there will be problems in the deployment of large-scale virtualized environments. The number of VLANs is only 12 bit units in the standard definition, and the available number is about 4,000. Such an order of magnitude is for public Cloud or large virtualized cloud computing applications are trivial. Based on this driving force, Overlay's virtualized network technology trend has evolved gradually. FabricPath Header Introduction Overlay in the field of network technology refers to a virtualization technology mode superimposed on the network architecture. Its general framework is to implement the application of the network on the network without large-scale modification of the basic network and can be used with other networks The business is separated and based on the basic network technology based on IP. In fact, this model is formed by optimizing traditional technology. In response to the three major technical challenges presented above, Overlay provides a completely new solution. Host, Network, and Hybrid Overlays Solution for the limitation of virtual machine migration scope limited by network architecture Overlay is a new data format encapsulated in IP packets. Therefore, this data can be distributed in the network by routing, and the routing network itself has no special network structure restrictions and has a benign large-scale scalability And there are no special requirements for the device itself, preferably with high-performance routing and forwarding, and the routing network itself has strong fault self-healing ability and load balancing ability. Solution for the limitation of virtual machine size limited by network specifications After the virtual machine data is encapsulated in the IP data packet, it only appears to the network as the encapsulated network parameters, that is, the address of the tunnel endpoint. Therefore, for the bearer network (especially the access switch), the MAC address specification requirements are greatly reduced The minimum specification is dozens (the tunnel endpoint MAC of a physical server per port). Solution to the limitation of network isolation / separation capability In view of the limitation of the number of VLANs within 4000, a user ID like 12-bit VLAN ID is introduced in Overlay technology, which supports user identification of more than 10 million levels, and the concept of cloud computing "tenant" is followed in Overlay, which is called Tenant ID (tenant identification), represented by 24 or 64 bits. In response to the problem of TRUENK ALL (VLAN penetrating all devices) of the network under VLAN technology, Overlay has no requirements for the VLAN configuration of the network, which can avoid the waste of invalid traffic bandwidth of the network itself. At the same time, Overlay's Layer 2 connectivity is created based on virtual machine business requirements. Globally controllable in a cloud environment. Overlay Taxonomy Three main technologies of Overlay Currently, the IETF has the following three major technical routes in the Overlay technology field. For simplicity, this article only discusses IPv4-based Overlay-related content. VXLAN VXLAN is a tunnel forwarding mode in which Ethernet packets are encapsulated on the UDP transport layer. The destination UDP port number is 4798; IP, Layer 4 port number, etc.) HASH value is used as UDP number; uses 24 bits to identify the layer 2 network segment, called VNI (VXLAN Network Identifier), similar to the role of VLAN ID; unknown purpose, broadcast, multicast and other networks Traffic is encapsulated as multicast forwarding, and the physical network is required to support any source multicast (ASM). NVGRE The main supporter of NVGRE is Microsoft. Unlike VXLAN, NVGRE does not use the standard transmission protocol (TCP / UDP), but uses the General Routing Encapsulation Protocol (GRE). NVGRE uses the lower 24 bits of the GRE header as the tenant network identifier (TNI) and can support 1,600 virtual networks like VXLAN. In order to provide a stream that describes the granularity of bandwidth utilization, the transmission network needs to use GRE headers, but this causes NVGRE to be incompatible with traditional load balancing. This is the biggest difference between NVGRE and VXLAN. To improve load balancing capabilities, it is recommended that each NVGRE host use multiple IP addresses to ensure that more traffic can be load balanced. NVGRE does not need to rely on flooding and IP multicast for learning, but broadcasts in a more flexible way, but this needs to rely on hardware / vendors. The last difference is about fragmentation. NVGRE supports reducing the maximum packet transmission unit to reduce the size of the internal virtual network packet, without requiring the transmission network to support the transmission of large frames. STT STT uses the data encapsulation form of TCP, but transforms the transmission mechanism of TCP. Data transmission does not follow the TCP state machine, but a newly defined stateless mechanism, redefines the meaning of each TCP field, and does not need three handshake to establish a TCP connection It is called stateless TCP; Ethernet data is encapsulated in stateless TCP; 64-bit Context ID is used to identify the layer 2 network segment; in order to make STT make full use of the balance of the network routing, the original Ethernet data header (MAC, IP , Layer 4 port number, etc.) as the source port number of stateless TCP; network traffic such as unknown destination, broadcast, and multicast are encapsulated as multicast forwarding. The general idea of ​​these three Layer 2 Overlay technologies is to carry Ethernet packets to a certain tunnel level. The difference lies in the choice and construction of the tunnel, and the bottom layer is IP forwarding. The table above shows a comparison of the key features of these three technologies: VXLAN and STT have low requirements for traffic balancing on existing network devices, that is, load link load sharing has good adaptability. General network devices can perform link aggregation or equal-cost routing traffic balancing on L2-L4 data content parameters. NVGRE requires network devices to perceive GRE extension headers and HASH flow ID, which requires hardware upgrades; STT has a major modification to TCP, the tunnel mode is close to the UDP nature, the tunnel construction technology is innovative, and the complexity is relatively high, and VXLAN uses the existing general UDP transmission, and the maturity is extremely high. Overall, VLXAN technology has a comparative advantage.
