community Design points and add-ons | 922-090 Real Questions and VCE Practice Test

This chapter is from the booklet 

As you create a network protection coverage, you ought to define techniques to guard your community and users towards harm and loss. With this aim in intellect, a network design and the protected components play a vital position in enforcing the ordinary protection of the company.

An typical security solution includes design facets and add-ons akin to firewalls, VLANS, and perimeter community boundaries that distinguish between inner most networks, intranets, and the information superhighway. This area discusses these elements and should help you inform them aside and consider their feature in the safety of the community.

Demilitarized Zone

A demilitarized zone (DMZ) is a small community between the inside network and the web that provides a layer of safety and privacy. both interior and external users may additionally have restrained access to the servers within the DMZ. determine three.three depicts a DMZ.

commonly, net and mail servers are positioned in the DMZ. because these gadgets are uncovered to the information superhighway, it's critical that they are hardened and patches are saved latest. desk 3.2 lists the most ordinary functions and ports which are run on servers interior the DMZ.

desk three.2. regularly occurring Ports on Servers within the DMZ









fifty three




one hundred ten




The DMZ is a neighborhood that enables exterior users to entry information that the organization deems integral however will now not compromise any inside organizational counsel. This configuration makes it possible for outside access, yet prevents external clients from without delay having access to a server that holds internal organizational data.


An intranet is a component of the interior community that uses web-based applied sciences. The suggestions is saved on web servers and accessed the usage of browsers. however web servers are used, they don’t always have to be purchasable to the outdoor world. here is possible since the IP addresses of the servers are reserved for private, interior use. You study more about private IP addresses within the “NAT” section, later during this chapter. If the intranet can also be accessed from public networks, it would be via a digital private network (VPN) for safety causes. VPNs are described in more desirable detail in Chapter 6, “Securing Communications.”


An extranet is the general public element of the enterprise’s IT infrastructure that enables materials to be used by way of licensed companions and resellers which have relevant authorization and authentication. This type of association is ordinary for enterprise-to-business relationships. because an extranet can provide legal responsibility for an organization, care must be taken to ensure that VPNs and firewalls are configured adequately and that security policies are strictly enforced.

virtual native enviornment network

The intention of a digital local area community (VLAN) is to unite network nodes logically into the same broadcast domain inspite of their actual attachment to the community. VLANs deliver a means to restrict broadcast traffic in a switched community. This creates a boundary and, in essence, creates assorted, isolated LANs on one switch. because switches operate on Layer 2 (information link layer) of the OSI mannequin, a router is required if information is to be passed from one VLAN to an extra.

body tagging is the know-how used for VLANs. The 802.1Q common defines a mechanism that encapsulates the frames with headers, which then tags them with a VLAN id. VLAN-mindful community devices search for these tags in frames and make acceptable forwarding selections. A VLAN is definitely a utility solution that permits developing entertaining tag identifiers to be assigned to distinctive ports on the switch.

the most extraordinary benefit of using a VLAN is that it will probably span distinctive switches. because users on the equal VLAN don’t should be linked by means of physical vicinity, they can also be grouped by way of branch or function. here are the advantages that VLANs give:

  • users will also be grouped by using department in preference to actual vicinity.
  • relocating and including clients is simplified. No remember the place a user physically moves, adjustments are made to the application configuration within the switch.
  • as a result of VLANs permit users to be grouped, making use of safety policies turns into more convenient.
  • take into account that use of a VLAN isn't an absolute protect towards security infringements. It does not give the same stage of security as a router. A VLAN is a software answer and cannot take the place of a well subnetted or routed community. it is viable to make frames hop from one VLAN to another. This takes ability and skills on the a part of an attacker, however it is viable. For more information about frame tagging and VLANs, see the “counseled analyzing and substances” section at the conclusion of the chapter.

    network handle Translation

    community handle Translation (NAT) acts as a liaison between an internal network and the internet. It allows for distinctive computers to connect to the information superhighway the usage of one IP tackle. a vital safety element of NAT is that it hides the inner network from the outdoor world. in this circumstance, the inside community makes use of a personal IP handle. special stages in each IP tackle class are used particularly for private addressing. These addresses are regarded nonroutable on the cyber web.

    listed here are the private address stages:

  • class A— network. legitimate host IDs are from to
  • classification B—172.sixteen.0.0 via networks. valid host IDs are from through
  • category C— network. valid host IDs are from to
  • For smaller companies, NAT can also be used in the form of windows information superhighway Connection Sharing (ICS), where all machines share one information superhighway connection, akin to a dial-up modem. NAT can also be used for handle translation between varied protocols, which improves safety and gives for greater interoperability in heterogeneous networks.


    Subnetting may also be done for a few motives. if you have a class C tackle and 1,000 valued clientele. you'll must subnet the community or use a custom subnet masks to accommodate the entire hosts. essentially the most ordinary reason networks are subnetted is to handle community site visitors. Splitting one community into two or more and the use of routers to connect each subnet collectively means that proclaims can be restrained to each subnet. youngsters, regularly networks are subnetted to improve network protection, not simply efficiency. Subnetting lets you arrange hosts into the diverse logical companies that isolate each subnet into its own mini network. Subnet divisions will also be in line with enterprise desires and protection policy goals. as an example, most likely you utilize contract people and need to retain them separated from the organizational personnel. frequently, organizations with branches use subnets to maintain every department separate. When your computers are on separate physical networks, you can divide your network into subnets that permit you to make use of one block of addresses on distinct actual networks. If an incident happens and also you notice it right now, you can always include the problem to that particular subnet.

    word that the 127 community address is missing. despite the fact the network is in technically in the classification A enviornment, the use of addresses during this range reasons the protocol software to return records devoid of sending site visitors throughout a network. for instance, the tackle is used for TCP/IP loopback testing, and the handle is used with the aid of most DNS black lists for checking out applications. should you want extra review on IP addressing and subnetting, a wide variety of guidance is purchasable. One such site is Learntosubnet.com. determine three.4 indicates an inside community with two distinct subnets. notice the IP addresses, subnet masks, and default gateway.

    Figure 3.4

    determine 3.4 A segmented community. notice the subnets and recognized subsequent to the router. These don't seem to be legitimate IP addresses for a community router and are used to establish the 192.168.1.x and 192.168.2.x networks in routing tables.

    IPv6 is designed to substitute IPv4. Addresses are 128 bits in preference to the 32 bits utilized in IPv4. just as in IPv4, blocks of addresses are set aside in IPv6 for personal addresses. In IPv6, internal addresses are called pleasing native addresses (ULA). Addresses beginning with fe80: are referred to as link-native addresses and are routable only in the local link area. IPv6 addresses are represented in hexadecimal. For more suggestions about IPv6, seek advice from http://www.ipv6.org/.

    community Interconnections

    besides securing ports and protocols from outdoor attacks, connections between interconnecting networks should be secured. This circumstance may also come into play when a firm establishes community interconnections with partners. This may be within the kind of an extranet or specific connection between the worried agencies as in a merger, acquisition, or joint task. company companions can encompass government groups and industrial organizations. however this type of interconnection raises functionality and reduces prices, it may end up in protection dangers. These dangers consist of compromise of all related techniques and any network linked to these methods, along with publicity of data the methods handle. With interconnected networks, the advantage for hurt tremendously raises because one compromised device on one network can with no trouble unfold to other networks.

    Organizational guidelines should require an interconnection settlement for any device or community that shares advice with one other exterior system or network. groups should cautiously consider risk-management methods and confirm that the interconnection is correctly designed. The partnering organizations have little to no manage over the management of the different celebration’s gadget, so devoid of cautious planning and assessment, each parties can be harmed. country wide Institute of standards and expertise (NIST) particular book (SP) 800-47, security e book for Interconnecting guidance know-how programs, offers tips for any organization that is seeing that interconnecting with a government agency or other company.

    network access manage

    One the most beneficial the right way to offer protection to the community from malicious hosts is to use community access handle (NAC). NAC offers a method of enforcement that helps make sure computer systems are effectively configured. The premise at the back of NAC is to comfy the ambiance by inspecting the user’s computer and in keeping with the consequences supply (or now not provide) entry for that reason. it is in response to assessment and enforcement. as an instance, if the user’s desktop patches aren't updated, and no desktop firewall application is installed, which you could make a decision even if to restrict entry to network supplies. Any host computing device that doesn’t agree to your described coverage can be relegated to remediation server, or placed on a visitor VLAN. The primary add-ons of NAC products are

  • entry requestor (AR)—here is the gadget that requests entry. The evaluation of the machine may also be self-performed or delegated to a different equipment.
  • coverage determination element (PDP)—here's the device that assigns a coverage in keeping with the assessment. The PDP determines what access should still be granted and might be the NAC’s product-management equipment.
  • coverage enforcement element (PEP)—this is the device that enforces the policy. This gadget may well be a swap, firewall, or router.
  • The 4 approaches NAC techniques can also be integrated into the network are

  • Inline—An appliance within the line, constantly between the access and the distribution switches
  • Out-of-band—Intervenes and performs an assessment as hosts come online and then supplies appropriate entry
  • change primarily based—corresponding to inline NAC apart from enforcement happens on the swap itself
  • Host primarily based—depends on an installed host agent to examine and enforce entry coverage
  • moreover presenting the skill to implement security policy, include noncompliant users, and mitigate threats, NAC presents a couple of enterprise advantages. The company benefits consist of compliance, a stronger security posture, and operational cost management.


    The transmission of information via machine in a telecommunications environment is known as telephony. Telephony comprises transmission of voice, fax, or other statistics. This area describes the components that should be regarded when securing the ambiance. often, these add-ons are omitted because they don't seem to be in fact network components. although, they use communications device it is liable to attack and for this reason have to be secured.


    The telecommunications (telecom) equipment and private department trade (PBX) are a essential part of a company’s infrastructure. anyway the typical block, there are additionally PBX servers, the place the PBX board plugs into the server and is configured via application on the desktop. Many businesses have moved to Voice over IP (VoIP) to integrate computer telephony, videoconferencing, and document sharing.

    For years PBX-type programs had been centered by hackers, in particular to get free long-distance carrier. The vulnerabilities that cell networks are area to consist of social engineering, lengthy-distance toll fraud, and breach of statistics privateness.

    To protect your network, be sure the PBX is in a comfy enviornment, any default passwords were modified, and simplest approved protection is carried out. many times, hackers can gain access to the mobile equipment by the use of social engineering because this device is continually serviced through a remote maintenance port.

    Voice over web Protocol

    VoIP uses the cyber web to transmit voice information. A VoIP device may be composed of numerous accessories, together with VoIP phones, computer techniques, PBX servers, and gateways. VoIP PBX servers are vulnerable to the same category of exploits as other network servers. These attacks consist of DoS and buffer overflows, with DoS being the most universal. additionally, there are voice-particular attacks and threats. H.323 and Inter Asterisk exchange (IAX) are specifications and protcols for audio/video. They allow VoIP connections between servers and enable client/server communication. H.323 and IAX protocols may also be prone to sniffing all through authentication. This allows for an attacker to attain passwords that may be used to compromise the voice community. Session Initiation Protocol (SIP) is widely used in immediate messaging, nevertheless it can also be used as an choice for VoIP. using SIP can depart VoIP networks open to unauthorized transport of facts. Man-in-the-middle attacks between the SIP cell and SIP proxy enable the audio to be manipulated, inflicting dropped, rerouted, or playback calls. Many accessories contain a VoIP network, and VoIP protection is built upon many layers of average records protection. for this reason, access can be received in a lot of areas.

    enforcing here options can assist mitigate the hazards and vulnerabilities associated with VoIP:

  • Encryption
  • Authentication
  • information validation
  • Nonrepudiation
  • Modems

    Modems are used via the telephone line to dial in to a server or desktop. they are regularly being replaced through excessive-velocity cable and Digital Subscriber Line (DSL) solutions, which are quicker than dial-up entry. youngsters, some businesses nevertheless use modems for employees to dial into the community and work from home. The modems on network computer systems or servers are usually configured to take incoming calls. Leaving modems open for incoming calls with little to no authentication for users dialing in will also be a transparent security vulnerability within the network. for example, warfare-dialing assaults take competencies of this condition. warfare-dialing is the technique by which an automatic utility application is used to dial numbers in a given range to examine whether any of the numbers are serviced with the aid of modems that settle for dial-in requests. This assault may also be set to goal related modems that are set to obtain calls without any authentication, thus enabling attackers an easy path into the community. you could resolve this issue enviornment in a few techniques:

  • Set the callback points to have the modem name the user returned at a preset number.
  • be certain authentication is required the usage of mighty passwords.
  • be certain employees have not set up modems at their workstations with far flung-control utility put in.
  • Cable and DSL modems are typical at the present time. They act more like routers than modems. although these devices aren't liable to struggle-dialing attacks, they do current a certain amount of danger by using retaining an at all times-on connection. if you go away the connection on the entire time, a hacker has ample time to get into the computer and the community. the use of encryption and firewall solutions will assist maintain the atmosphere secure from assaults.
