Classified acc. to EN 298BTLLXN2TECHNICAL FEATURES 1. Flame detectionThe following types of flame detector can be used:-Ionisation electrode, where the mains supply provides a neutral earth connection. Suitable for gas burners (signal current from flame cannot be influenced by interference from ignition spark).-UV sensor type UVZ 780 red, suitable for gas, oil and dual fuel burners.-Infra-red flicker detector type IRD 820 and 1020 for all types of burner.The flame signal amplifier is adjusted to the the type of detector probe fitted by using the flame detector selection switch on the underside of the unit. If the IRD flicker detector is used, the selection switch must be adjusted to the "ION"position.Flame detection is only operational when the switch position selected corresponds to the type of detector probe connected.By optimally matching the amplifier to the detector probe,considerably longer signal transmission distances with less sensitivity to interference can be achieved.The flame signal current indicator consists of a five stage LED display which shows the signal current continuously.An indication of the strength of the flame signal current is therefore always given. Fluctuations in the monitoring sensitivity can be noticed at an early stage,and appropriate corrective action can be taken.If the infra-red flicker detector IRD 820 or 920 is employed, the flame signal current indicator on the control box is not relevant. In this case, the IRD indicator is the decisive indication of flame signal strength.Flame signal current indicator2. Burner Control-Burners can be operated with or without post-purge.This varies according to model (see technical data)and is activated when the burner motor is connected to terminal 19.-Air damper operation is monitored to ensure the nominal air volume during pre-purge and in the starting position before fuel is released. If confirmation of the damper positions "MIN" and "MAX" is not received, the control box start sequence is interrupted.-The air proving switch is checked for corrrect operation before the start, and air pressure is monitored during pre-purge as well as during normal operation. In normal use,switch contacts with a rating of 6A/220V are sufficient.Additional switch contacts which are to be monitored can be connected between terminal 18 and the air proving switch working contact. In this case, jumper II on the underside of the control box should be cut.-A separate connection for a pilot valve PV is provided,which is again closed at the end of the second safety interval. The heat output of the gas flow which is controlled by this valve must not exceed 120kW.-The terminal for the start valve SV must not be used when connecting the pilot valve PV.-Together with the start valve SV, a total of 3 power levels are available for use. The gas flow controlled by valves SV, V1 and V2 must lead to a common nozzle unit.- To determin the heating power of the gas flow controlled by the pilot- and start valve, EN 676 has to be consulted.-In addition to the built-in button with signal lamp, it is also possible to connect a remote lockout indicator and reset switch.-For monitoring of the ignition spark, link 1 on the base of the control box must be cut. In this case, flame detection is carried out by a UVZ 780 ultra-violet sensor.3. SafetyThe design and programme sequence employed in the control boxes in the TMG 740-3 series conform to the presently applicable European standards and regulations.The following features exceed the requirements of most standards, and therefore ensure additional safety:-After a normal shutdown, the stray light test is started immediatly by the control box which directs an increased voltage to the UV sensor. The very important extinguishing function of the sensor can therefore be checked. If the fuel valve does not close correctly, or a sensor or amplifier malfunction occurs, shutdown and lockout take place after approx. 20 sec., even if the controlling thermostat is open.-The contacts responsible for the release of fuel are checked when the programme starts, to ensure that they have not become welded together.4. Mounting and Electrical InstallationAt the base:-3 earth terminals, with an additional tag for the burner earth.-3 neutral terminals, with a fixed internal through connection to the neutral input, terminal 8.-2 separate slide-in plates and 4 fixed, threaded knockouts (PG 11 thread) as well as a wiring opening from below, to facilitate wiring of the base.-A keyed fit ensures that the wrong control box type cannot be fitted to the base. The corresponding control box designation is shown in lettering on the base.General:-Can be mounted in any position, insulated as per IP 44standard (unaffected by water spray). The control box and detector probes should not however be subjected to excessive vibration. With the UVZ 780 ultra-violet sensor,care should be taken to ensure that a good electrical contact to the burner exists via the metal flange.-If an ionisation electrode is used, appropriate protective measures are required in order to avoid contact with the electrode while installation work is being carried out.Trouble-free operation with this type of flame detection is not possible if a voltage of over 25 volts is measured between neutral and earth. In this case, provision must be made for a separate isolating transformer.-The maximum lengths for the detector probe cables,depending on the type of cable installed, are listed in the technical data and must be adhered to without fail. Laying the cables parallel to mains cabling over long distances should be avoided, and the use of multiple core cable is also not permitted.T M G 740-34COMMISSIONING AND MAINTENANCE 1. ImportantThe wiring must be checked exactly when commissioning the installation. Incorrect wiring could damage the control box, putting the safety of the burner system at risk.When mounting and wiring the control box, the applicable installation regulations must be observed.-The chosen fuse rating must not, on any account, be higher than the value listed in the technical data.-Failure to observe this instruction could, in the case of a short circuit, have serious consequences for the control box or burner system.-For safety reasons, it must be ensured that the control box performs at least one normal shutdown during every 24 hour period.-Switch off or disconnect the power before plugging in or unplugging the unit.-Burner control boxes are safety devices and should not be opened.T M G 740-32. Routine ChecksAn inspection of the technical safety of the flame detection system must be carried out during commissioning of the unit as well as after servicing, or if the system has not been in operation over a long period.For test a), the gas proving switch should be bridged.a)Attempt to start with the hand valve closed:- After the first safety interval has elapsed -> Lockoutb)During normal operation, interrupt detector probe or cutoff light:- In less than 1 sec.-> LockoutFault findingFault finding is considerably simplfied by making use of the coloured programme indicator. Irregularities during commissioning, normal operation or a normal shutdown pause can be localised via the programme indicator disc.If a malfunction occurs, it is useful to note the exact position of the indicator before operating the control switch or reset button.The following list is designed to assist with fault finding.COLOUR WHERE WHAT REASONBLUEbeginningdoesn’t start-no power, break in control circuit, air proving switch not in resting positioncontinuous ventilation -end switch "MAX" air damper doesn’t operateline lockout-air proving switch doesn’t switch over or is too lateendcontinuous ventilation -end switch "ignition position", air damper doesn’t operate anywherelockout -stray lightYELLOWendlockout-flame establishment pilot or start valve impossible no flame signal current or too weak (min. 2 LED’s) flame detector selector switch set incorrectlyRED end lockout-no flame signal current or too weak after end of second safety interval (double fuel feed burner)GREEN end lockout -loss of flame during operation, air pressure too low BLACKendlockout-stray light due to burning on, UVZ sensor tube reached end of life and activates shutoff, defect in flame detector circuitA test baseplate is available for checking the burner control box functions (model designation UP 7520, item no. 18601)6Honeywell-Platz 1Postfach 324CH-8157 DielsdorfORDERING INFORMATION ITEM DESIGNATION ITEM NO.Burner control box Type TMG 740-3 Mod. 32-3208211Socket Socket TMG 70205Insert plate PG-plate 70502optional Cable entry plate 70501Flame detector UVZ 780 white 18814or UVZ 780 blue 18812or UVZ 780 red 18813Flame detector IRD 82016201Flame detector IRD 1020 end-on viewing 16522Flame detector IRD 1020 side-on left 16523Flame detector IRD 1020 side-on right 16521IRD mounting flange IRD Holder M9359093Flame detector cable 3-wire, 0.6 m7236001The above ordering information refers to the standard version.Special versions are also included in our product range.Specifications subject to change without notice.。

The flame detector IRD 910must be replaced by its compatible type IRD 1010.An optional extension button (item no. 70601)compensates for height differences.COMMISSIONING AND ROUTINE CHECKS1. Important notes–The controls must be installed by qualified personnel only. The relevant national regulations have to be observed.–On commissioning the wiring has to be carefully checked according the appropriate diagram, Incorrect wiring can damage the unit and endanger the installation.–The fuse rating has to ensure that the limits specified in TECHNICAL DATA will not be exceed. If these precautions are not observed, the effect of a short circuit can cause severe damage to the control and installation.–For safety reasons a minimum of one control shut-down per 24 hours has to be observed.–Disconnect the mains before the control box is plugged in or out!–The control box is a safety device and must not be opened!2. Function controlFor safety reasons the flame detection system should be tested on commissioning the installation as well as after a service or longer shut-down.Prerequisite: mains voltage >187 V eff (for TF801.2 and TF 802.2 only)a)Start-up with covered flame detector–After lock-out safety time is over the unit has to go in to lockout mode!b)Start-up with exposed flame detector:–After 20 sec. pre-purge time the unit has to go into lockout mode!c)Normal start-up with burner in the normal position, cover up the flame detector:–After start-up, and end of lock-out safety time the unit has to go into lockout mode!d) The flame sensor signals can be checked either using the UP 940 or performing the following measurements:–For TF801 and TF802 only: The measured sensor signal during operation should be minimal 2.4mA –F or TF 801.2 and TF 802.2 only: The sensor signal measurements are not reliable, as only marginal values changes occur. Measure instead the voltage across the photo resistor! F or a reliable flame monitoring the DC voltage across the photo resistor (terminal 1 and 2) in operating mode should be less than 2 V.3. Fault findingsBurner is not working:–thermostat circuit open –faulty electrical wiring–mains voltage <187 V eff (for TF801.2 and TF 802.2 only)Burner starts, but the flame does not establish, a lock out occurs:–stray light on flame detector –no ignition or no fuelBurner starts, the flame establishes, but after the safety time, a lock out occurs:–dirty or faulty flame detector –insufficient light on detector–sensitivity adjustment too low on IRD.For a quick and safe diagnosis use the Honeywell UP 940burner test box.APPLICATION NOTES1. Flame controlThe following detectors can be used for flame control:–F or yellow oil flame: photoresistor F Z 771 S (red inscription: side-on; white inscription: side-on and end-on viewing)–for blue or yellow flame: infrared-flicker detector type IRD 1010 or as alternative the UV solid state sensor UVD 970.Using the photo resistor FZ 711 S, the no flame signal is generated at light levels below 3 Lux with respect to the operating cycle of the control. According to DIN74787 and EN 230 stray light safety level has to be established in conjunction with the accompanying burner.Connecting the IRD 1010 or the UVD 970, the correct wiring has to be observed.2. Burner controlFor burners without an oil solenoid valve, the burner motor has to be connected to terminal 5.3. Low-voltage protection TF 801.2 and TF 802.2 only–The mains voltage has to be more than 187 V eff in order to allow the unit to perform a start-up.–The mains voltage is not only monitored in the start-up phase but also permanently during operation. If the voltage drops below <160 V eff during start-up or run time the control box goes into lockout mode. If the voltage rises again, the control box performs automatically a start-up as soon as the mains voltage is >187 V eff .4. SafetyThe design and control sequence of the TF 801/TF 801.2and TF 802/TF 802.2 control boxes comply with the currently applicable European standards and regulations.6. Mounting and electrical wiring Wiring base:– 3 earth terminals with additional terminal for burner earthing– 3 neutral terminals with internal permanent connection to neutral terminal (terminal 7)– 2 spare auxiliary terminals– 2 slide in plates and 2 easy-knockout holes (PG 11thread), plus 2 easy-knockout holes in the bottom of the base facilitate the wiring.–The 3-wire sensor cable can be used for the IRD and UVD as well as for the FZ711 S. Please keep that in mind for burners which may be upgraded from FZ to IRD or UVD later on (e.g upgraded to a blue flame burner).General:–The control box can be mounted in any position. The protection class is IP44 (water spray tight). Neither the control box nor the flame detector should be subjected to excessive vibration.801/801.2 802/802.2801/801.2 802/802.2ORDERING INFORMATIONITEM DESIGNATION ITEM NO.

ir3火焰探头工作原理
ir3火焰探头工作原理The working principle of IR3 flame detector is based on the detection of infrared light emitted by flames. IR3 flame detectors use infrared sensors to detect specific ranges of infrared radiation that are emitted by flames. When a flame is present, it emits infrared light in the IR3 wavelength range, which can be detected by the sensor in the flame detector.IR3火焰探测器的工作原理是基于红外线发射的检测。
IR3火焰探测器使用红外传感器来检测火焰发出的特定红外辐射范围。
当有火焰存在时,它会在IR3波长范围内发射红外光,这可以被火焰探测器中的传感器检测到。
One of the key components of an IR3 flame detector is the infrared sensor. This sensor is designed to specifically detect infrared light in the IR3 wavelength range. When infrared light in this range is detected, the sensor sends a signal to the detector to indicate the presence of a flame. This signal can then be used to trigger an alarm or take other safety measures.IR3火焰探头的核心部件之一是红外传感器。

This system does not require a foam concentrate supply pump.SPECIFICATIONThe Bladder Tank Foam Proportioning Systems are available with vertical and horizontal bladder tanks. The carbon steel tanks are designed and constructed in accordance with ASME Code Section Vlll Div.1 for unfired pressure vessels. The maximum working pressure is 12 Bar (175 PSI). The vertical tank assembly is supported by legs welded to tank with provision for anchoring. The horizontal tanks are supported by two saddles welded to the tank and drilled for anchoring. Tank is provided with lifting lugs.The system is supplied with pressure vessel, bladder , fill and drain valve for water and foam concentrate, ratio controller and vent valve. Ladder and sight gauge assembly are supplied as optional items on request.All valves are labeled showing normal working position and function.All tanks are oversized for allowing thermal expansion of the foam concentrate, if any.PRINCIPLE OF OPERATIONThe instructions for filling are provided with the equipment. Once the main water flow is established and water inlet and foam outlet valves are opened, the water enters the area between vessel wall and bladder , applying pressure to the bladder . The foam concentrate is forced out of the bladder through the foam concentrate outlet pipe and into the ratio controller through metering orifice. The concentrate pressure and water inlet pressure at ratio controller will be same, as the main water supply pressure is utilised to expel the foam from the bladder . The water flowing through the ratio controller jet creates a low pressure area common both to down stream water and foam concentrate. This injects the concentrate in to the ratio controller through an accurate sized orifice proportioned to water venturi. This ensures correct proportioning over a wide range of flow condition.The bladder tank proportioning system operates on same principle as that of a balance pressure proportioning system. In bladder system, the bladder is used as diaphragm to separate the water and foam concentrate within the tank. The foam concentrate is injected into the ratio controller utilising water pressure.The system is also supplied with foam concentrate control valve as an optional item. The valve allows concentrate flow only when minimum of 2.1 kg/sq.cm. water pressure is established in the system. For pressure drop and flow characteristics refer catalogue of ratio controller .HD FIRE Bladder tanks and proportioners are UL Listed and FM Approved with various HD foam concentrates, refer indivisual listing and approval data.“U’ stamp (American Society & Mechanical EngineersASME) code stamp. This ASME certification is optional.Bladder tanks 900 Liters and larger are CE marked on conformance with the European Pressure EquipmentDirrctries. CE marking is optional.SELECTION OF HORIZONTAL /VERTICAL BLADDER TANKSAdvantages of Horizontal bladder tanks (i) Better stability than vertical tank in earthquake prone area (ii) Easier to refill than vertical tanks (iii) Easy to transport, store and install (iv) Large CapacityAdvantages of Vertical bladder tanks(i) Require less floor space than horizontal tanksINSTALLATION, INSPECTION AND MAINTENANCEAn installation, inspection and maintenance manual is packed with each unit. The manual provides detail schematic, initial procedure, inspection and maintenance procedures. The instruction manual must be read carefully and followed during installation and commissioning of the system.After few initial successful tests an authorised person must be trained to perform inspection and testing of the system. It is recommended to carry out physical inspection of the system regularly, the inspection should verify that no damages have taken place to any component and all the valves are in their proper position as per the system requirement. The system should be fully tested at least once in a year and in accordance with applicable NFPA code or in accordance to the guidelines of the organisation having local jurisdiction.Do not turn off the system or any valve to repair or test the system, without placing a roving Fire Patrol in the area covered by the system. The patrol should continue until the system is put back in service. Also inform the local security personnel and the control room so that a false alarm is not signalled.CAUTION1) Do not weld on the tank as it may damage the bladder fitted inside the tank.2) Release pressure before an inspection and maintenance of the system.3) Sight gauge is not pressure tight, so before taking concentrate level reading, tank pressure must be released.4) The bladder tank is to be installed under a shade to avoid direct sunlight on the equipment.5) While designing a foam system, step shall be takento allow for removal of the internal centre tube(s). The centre tubes are full length and/or height ofthe bladder tank.6) ASME Code may require over pressure protection before pressurising the system. HD FIRE does not supply an over pressure relief valve with the tanks. It shall be the owner’s responsibility to provide over pressure protection for thetank in accordance to ASME Code.7) Foam concentrate filling procedure mustbe followed. Incorrect filling procedure may damage the bladder . HD product have limited warranty and incorrect fill procedure will void the warranty.NOTE1) The foam concentrate is to be filled in the bladdervery carefully to avoid rupture of bladder.The filling guidelines provided with the equipmentmust be strictly adhered.2) Air supply with regulator (0 to 1.0 kg/sqcm)required during filling procedure, to be arrangedby installer / user.3) Water supply at 0-1.5 kg/sqcm required fortank filling during commissioning, to be arrangedby installer / user.4) Concentrate fill pump need to be arranged byinstaller / user.5) A minimum length of 5 (five) times the pipediameter of unobstructed straight pipelineshould be provided at the inlet and outlet of theratio controller, where pipe diameter is thenominal size of the ratio controller.6) For FM Approval of Bladder tank is applicableonly FM Approved Bladder tank, Ratio Controller, Foam Concentrate and Dischage Deviceareinstalled.7) Concentrate control valve is requirement forFM Approval and is not permited by UL.Hence Tanks will be either UL Listed or FMApproved.8) Multiple Ratio Proportioners cannot be usedif it is UL Listed Bladder tank.9) FM Approved Bladder tank permits maximumtwo Ratio Controllers.10) Each tank is designed & tested for specifictype of foam concentrate, hence specify in order the concentrate type to be used.OPTIONAL SUPPLY• Sight gauge with shut off and drain valve (glass or polycarbonate material)• Ladder• Pressure Guages• Concentrate control valve• Filling kit with Foam concentrate fitting pump• Stainless steel pipe for water supply side• Stainless steel pipe & valve standard supply SS304/CF8.

FC410LI线路隔离器模块说明书
TECHNICAL SPECIFICATIONSystem Compatibility:Use only with FC Fire Alarm Controllers Environment:Indoor Application onlyOperating Temperature:-25to +70oCStorage Temperature:-40to +80oC Operating Humidity:Up to 95%non-condensing Dimensions (HxWxD):85x 60x 15mm Mounting Requirements:Dual-gang electrical backbox Recommended Wire Size:Min.1.5mm 2Max.2.5mm 2Maximum Wiring Resistance Monitored Circuit :10W Electromagnetic CompatibilityThe FC410LI complies with the following:Øproduct family standard EN50130-4in respect of Conducted Distur-bances,Radiated Immunity,Electrostatic Discharge,Fast Transients and Slow High Energy;ØEN61000-6-3for emissions.INTRODUCTIONThe FC410LI Line Isolator Module is designed to be used on the FC addressable controller loop circuits.It monitors the line condition and when detecting a short cir-cuit will isolate the affected section whilst allowing the rest of the addressing circuit to function normally.The purpose of the FC410LI Line Isolator Module is to ensure that,on a looped addressable system,no short circuit fault can disable more de-tection devices than would be lost on a conventional non-addressable fire circuit.INSTALLATION TO FC470CV ANCILLARY COVER1)Assemble the FC410LI to the FC470CV Double Gang cover,using the four screw and washers provided.2)Fit cover onto dual-gang backbox.CABLINGCables are to be selected in accordance with the system design document and the requirements of the applicable standards.One pair of terminals is used to provide a spur circuit (S+/S-).Two pairs of connection terminals (R+/R-and L+/L-)are provided on the terminal block.These terminals are used for connect-ing the module on to the addressable circuit.The maximum section of the cable that can be connected at any one terminal is 2.5mm 2.The section is calculated based on the characteristics of the cable and the load.WIRING NOTESThe following notes apply:1)There are no user-required settings (such as switches or headers)on the FC410LI.2)All wiring must conform to the applicable standards.3)All conductors to be free of earths.4)Connect loop wiring.For FC410LI typical wiring configurations (see Fig.1b).5)Verify the correct polarity of wiring before connecting the FC410LI to the addressable loop circuit.6)It is possible to connect a maximum of 32devices between two loop iso-lators (FC450IB o FC410LI),note that in the device counting process,each FC410MIO or each FC410SIO adds a double value.VERIFYING LOOP WIRING+WARNING:DO NOT MEGGER LOOP WIRING WITH LINEISOLATOR MODULES CONNECTED.The Line Isolator Module is not designed to work with line voltages above the specified maximum 40Vdc.This means that continuity testing of the loop wiring with Line Isolator Bases connected must be done using a voltage between 20-40Vdc.The resistance measurement range on conventional voltmeters use low voltage only,therefore,the following method can be employed to confirm loop integrity.A power supply capable of providing 30-40Vdc with a 300to 600mA current limit is connected to one end of the loop (in correct polarity).A voltmeter is connected to the other end of the loop or any base along the loop to verify the wiring up to that point.If there is no voltage out at any measured point,this may be due to:1)Loop Open Circuit -wiring incomplete to part of the loop.2)Incorrect Polarity -FC410LI Line IsolatorModules will appear as a short circuit if they are wired with incorrect polarity.3)Loop Short Circuit -If this occurs between two FC410LI Line Isolator Modules,it will isolate that section of the line,which will then appear as an open circuit.If this occurs between the supply and the first FC410LI Line Isolator Modules,the supply output will go low due to the internal current limit.ASSOCIATED EQUIPMENTThe module fits onto a standard dual-gang backbox.ORDERING INFORMATION FC410LI:Line Isolator Module FC470CV:Double-Gang CoverRECYCLING INFORMATIONCustomers are recommended to dispose of their used equipments (panels,detectors,sirens,and other devices)in an environmentally sound manner.Potential methods include reuse of parts or whole products and recycling of products,components,and/or materials.WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE)DIRECTIVEIn the European Union,this label indicates that this product should NOT be disposed of with household waste.It should be deposited at an appropriate facility to enable recovery andre-cycling.The manufacturer reserves the right to change the technical specifications of this product without prior

离子棒火焰探测器说明书
BC1000燃烧控制器特点1.结构紧凑,采用插入底座的方式,安装方便。
2.可直接面板安装,当面板上已有多种设备时为了方便安装,也能够嵌入安装到DIN 槽。
3.当安全启动检测在启动时,发现异常火焰情况存在,控制器将中断点火4.三个 LED灯分别指示运行时三个状态:电源,火焰,安全启动检测(SSC)5.火焰的强度可经过前面的端子测量,或连续测量监测。
归纳BC1000 是应用于大型商用及工业用燃烧装置上的火焰开关。
它拥有以下功能:1.简单的火焰开关功能,即指示有无火焰。
2.燃烧安全控制器,能够供应系统“安全启动检查”和火焰监测功能。
内置的安全启动检查电路用于在启动的同时检测火焰探测器可否能正常工作(当 1 端子得电时)。
若是此时显示有火焰存在,它便不会接通安全继电器,于是系统就不会在控制器获取启动信号时进行启动。
BC1000 需连接火焰离子棒或Honeywell mini-peeper UV紫外火焰探测器来探测火焰情况并为控制器输出火焰信号。

公司背景
全球总部位于美国堪萨斯城 全球第一个发布防火墙安全策略管理及网络设备
年营业额超过5亿美金,有超过5000个客户
Firemon的部分客户
防火墙与 防火墙安全策略(security rule)
防火墙与防火墙安全策略
防火墙是网络中部署最广泛的安全网关产 品之一,对用户信息系统的安全而言相当 关键;
防火墙的安全性基本是通过安全策略 (security rule)的配置来实现的
Actual implementation must match the approved design

Verify

Access Reqn
Firewall requests often don’t contain the information necessary to fully build the best access rule
ACL管理解决方案的厂商(2001年发布) 用户遍及全球各个行业,包括运营商(T-Mobile、
Verizon等)、金融(美国银行、纽交所、AXA安 盛人寿等)、大型企业(IBM、HP、Dell、壳牌石 油、eBay、美国航空等) 母公司为FishNet Security
全美最大的安全产品分销商,是Juniper, CheckPoint等 防火墙全美最大的Distributor
而经过优化,性能最高可提升30%以上;
安全策略对防火墙性能影响的实验
测试配置
IXIA IxLoad Objectives
5,000 HTTP conn 50 SMTP conn./sec 10 DNS conn./sec
CPU与安全策略数
5 rules: 27% load 187 rules: 44% load 264 rules: 48% load
时延影响
5 rules: 600 µ s 187 rules: 1800 µ s 264 rules: 2600 µ s
安全策略位置对性能的影响
将活跃安全策略位置向后移(rule 5 to rule 276),CPU负载提高超过10% 即使策略数目不变,策略位置的变动将直接影响到防火墙性能
常见问题:
哪些安全策略是多余的? 哪个或哪些安全策略被使用的最多、最频繁?而哪些策略没被使用
过? 这条安全策略的目的?谁配的?在起作用吗?可以删除吗? 某条安全策略下的流量构成是什么,流量的占比情况如何,特别是
那些’any’类型的安全策略?是否确实只有被允许的流量穿过这条 安全策略? 系统内的防火墙是否已经对已知的安全漏洞或者特定的危险端口进 行了安全策略防护?是否存在误配置或者遗漏的状况? 系统内防火墙的配置是否符合安全规范,如PCI、ISO27002等?如果 存在不符合,是哪些不符合?该如何修改?
防火墙管理员常见困惑
在防火墙的安全策略配置、变更时,包括新增策略、变更 策略,或者删除策略时,管理员操作依据较为模糊,缺少 相关的数据分析报告或者科学依据,从而有时会出现防火 墙安全策略配置上的缺陷或者错误,如过多不必要的策略、 过于复杂的策略,或者漏配一些需要的安全策略等等,这 给系统安全与稳定性带来隐忧;
因此,防火墙安全策略配置的正确对防火 墙的安全防护作用起着至关重要的作用
一台再好的防火墙设备,如果不配置安全策略, 或者安全策略的配置错误,那么这台防火墙不 仅根本无法起到其应有的安全防护作用,并且 还会带来许多安全隐患和安全事件
防火墙安全策略配置标准流程
Verification must include visibility to; proposed solution and technical implementation
其他安全管理难点
安全策略配置缺少与系统安全漏洞的关联, 使得防火墙安全策略的配置存在安全隐患
缺乏安全策略变更管理,造成安全策略误删除、 误修改事件
马来西亚某银行由于新管理员错误移动了某条安全策 略的位置(从第2条移动到较后位置),造成某关键业 务中断12小时
防火墙安全策略配置的典型问题
过多的、不必要的、重复的安全策略
统计表明,通常一个客户防火墙上约有30%~50%的防 火墙策略是多余的、不必要的;

Review
Correct change is critical for proper firewall access; this is the most important step in the process
Reviewing firewall access requests for validity is necessary to ensure risk is being effectively managed
安全策略只增不减:无法确定是否仍然有用,或者配 置后忘记删除,或者人员变化后新管理员无法了解原 有策略配置的原因等等
法国雅高集团:某防火墙cluster上配置的安全策略达 1000多条,后发现,超过700条是不必要的、重复的;
防火墙安全策略的低效率
过多的防火墙安全策略严重降低防火墙性能 安全策略的顺序、位置对防火墙性能也有明确影响 过于复杂的安全策略:过多的object等 不合理的安全策略配置将使防火墙性能下降30%以上,
配置错误造成大量防火墙安全事件
根据Gartner的统计,99%的防火墙安全事件均是 由防火墙的配置错误而引起
人为错误频发
2012年4月9日,美国犹他州Department of Health被偷 78条客户信息。该安全事件是由于管理员的配置错误而 造成的;
2012年7月,国内某银行由于某设备配置错误造成断网3 小时
