免费安全软件哪家强安全软件全体验—国产篇作者：任九州来源：《电脑爱好者》2017年第03期安全对于每一个人来说都非常重要，进入信息社会之后，越来越多的办公文档与个人信息都从纸面转移到了电脑中去，变成了一个又一个的1和0组成的字符。

科技发展让工作和娱乐更加方便多样的同时，安全问题也变得更为严峻。

日常生活中我们浏览各种网站、下载各种资源的时候一不小心就可能中了病毒和木马，它们会盗取账号偷走资料，也可能会利用用户的电脑变成“肉鸡”去攻击其他网站的服务器，或是打开电脑摄像头偷窥用户的日常生活。

为了保证电脑使用的安全，电脑安全软件很自然的就成为了装机必备软件之一。

1.微软免费提供MSE（MicrosoftSecurity Essentials）和系统自带防火墙，我们为什么还需要第三方的安全软件？确实微软的MSE杀毒软件小巧轻便、兼容性极佳，而且在Windows8之后的系统中还集成到了Windows Defender里面。

不过看似美好的MSE每次在杀毒软件排行当中总是以垫底的身份出现。

所谓“魔高一尺，道高一丈”，病毒与反病毒的斗争中病毒也在不断地升级，对于黑客来说，突破微软系统自带的防火墙和制作MSE无法查杀的病毒是最基本的专业知识。

显然“MSE+系统自带防火墙”这个“道”是远远不够的。

毕竟术业有专攻，微软很清楚自家系统的弱点和需要保护的地方，但是在反病毒技术的积累上比专业的安全软件厂商还是要差很多。

对于经常下载和对安全有一定需求的用户来说，选择一款靠谱的第三方安全软件显然是很需要的，如果只是日常办公，轻度使用，系统自带的防火墙和MSE也足够使用。

2.为什么是安全软件而不是杀毒软件以前我们使用电脑主要是使用杀毒软件进行病毒查杀，不过这是一种比较被动的方法。

杀到病毒之前我们要做的就是让电脑里先感染病毒。

就像是得病需要看医生一样，在得病之前最好的方法就是做足预防工作，让自己不会得病。

安全软件就是起到一个预防的作用，我们平时安装的安全软件可能缺少杀毒功能，但是能对系统漏洞进行修复和加固，及时清理用户的关键信息，在网络浏览时进行安全监控，尽可能减少中毒和被黑客利用的机会。

The user-friendly Trackball and Operator Keyboard make it very easy to select graphic mimic pages on the screen and to execute control commands or automatic control sequences.Workstations are installed on several locations on the vessel. Typical locations include:- 1 pc Workstation on Bridge- 2 pc's Workstation in Control Room- 2 pc's Workstation in Cargo Room- 1 pc Workstation in Chief Engineer cabinDepending on type of ship; this configuration is adapted to ship owner/ yard requirements. The system is designed for a maximum of 64 Workstations and a maximum of 65536 process points.All Workstations are inter-connected via a redundant High Speed Network; based upon Ethernet standard. Two Workstations are connected to the Mega-Guard I/O Controllers via a separate Fieldbus Network. The 'Main Server' Workstation is connected via the 'Main' Fieldbus link to the Mega-Guard I/O Controllers. The 'Back-up Server' Workstation is connected via the 'Back-up' Fieldbus link to the Mega-Guard I/O Controllers. All other Workstations ('Clients') communicate with the Main or Back-up Server Workstation via the redundant High Speed Network.2.1 Workstation system componentsA Workstation consists of the following components:- Marine Personal Computer- I/O Server Board (only applied for Workstations which are connected to Fieldbus (the Main Server and the Back-up Server))- Colour Graphic Flat Screen TFT Monitor- TrackballKeyboard- Operator- QWERTY Keyboard with integrated Trackball2.1.1 Marine Personal Computer type 6001-711The Marine Personal Computer is a ruggedized bulkhead mounted computer; designed for marine environments. The computer is loaded with Windows 2000 operating system and high resolution operator Workstation software. See paragraph 7.1 for specifications of the MPC. 2.1.2 I/O Server boardCommunication to the Mega-Guard distributed processing units (DPU's) takes place via at least 1 I/O Server board. For redundancy also a second I/O Server board is provided.An I/O Server board communicates with the Marine Personal Computer via a high speed parallel ECP/EPP interface link.Each I/O Server board is equipped with 4 Fieldbus links, which are typically used as follows: - Fieldbus 1 - Alarm Monitoring System & Cargo System- Fieldbus 2 - Power Management System- Fieldbus 3 - Remote Control System- Fieldbus 4 - Extension Alarm SystemThe Main Fieldbus link of the Mega-Guard modules is connected to the Main I/O Server and the Back-up Fieldbus link of the Mega-Guard modules is connected to the Back-up I/O Server. The I/O Server board is also equipped with 6 digital inputs and 6 digital outputs, which are used for the Extension Alarm System.2.1.3 Monitor, Trackball and Operator KeyboardThe Monitor is a Colour Graphic flat screen TFT. It displays the following pages when selected by the Trackball or Operator Keyboard:- Alarm Page (toggle between: Alarm Summary and Alarm History Page)- Group Page (logging and trending can be selected from the Group Page)- Graphic Page- ChannelPagePage- Diagnostic- General Page (Pop-up window with the following selection: Skip, Inhibit, Active Inhibit, Exit)The following printer functions can be selected:Print- DemandScreen- PrintThe Colour Graphic Flat Panel Screen is in full accordance with the high resolution VGA standard. It is available for desktop and for flush panel mounting. See paragraph 7.4 for the available sizes.designed for marine applications). In addition, we recommend the use of an Operator Keyboard (operator control panel). This panel is equipped with large keys for easy operation of the system. A text legend can be inserted under each key, allowing clear text descriptions in any required language.Control commands to start e.g. a cargo pump, generator set or a stand-by pump can be entered on the Operator Keyboard and/or selected via Trackball.With the Trackball via dedicated 'pop-up windows' displayed on the screen of the Colour Graphic Monitor it is possible to:- Select pages on the colour graphic monitor- Control the printer- Control trending and optional data logging- Enter control commands e.g. to start a generator set- Change control settings, e.g. to change a set-pointThe Operator Keyboard has a number of dedicated keys in order to:- Select pages on the colour graphic monitor- Control the printer- Control trending and optional data logging2.2 High Speed Network (based upon Ethernet 100-BASE-T)All Workstations are inter-connected via a redundant High Speed Network; based upon Ethernet technologies. The High Speed Network uses 2 category 5 unshielded twisted pair cables (UTP), one for main link and one for back-up link.The cables are routed in a star configuration. The 6001-721 Marine Personal Computer can be equipped with 100-BASE-T interface with a RJ45 type of connector for connection to the Network.The High Speed Network specifications are as follows:Cable type: Cat. 5 unshielded twisted pair (UTP) Cable connectors: RJ45 male.Minimum cable length between nodes: 0.5 meterMaximum total cable length without repeaters: 100 meterData rate: 100 MBitA switch must be installed if client workstations are required or when single segment cable length exceeds 100 meter.2.3 Redundant NetworkTo operate the network adapters the "Redundant network" application is available. This application decides if the main or backup network card is used. It checks both networks continuously and reports errors to the system as alarms.In the next picture the Redundant network application is shown, with explanations for eachpart of the main dialog.For more information about the redundant network application is referred to the "PTD Redundant Network" document.3 OPERATOR WORK STATION FUNCTIONSAlarms, process values and system conditions are presented to the operator on the Workstation in a variety of ways. Full alarm functions are provided on process values, error conditions and Mega-Guard system failures.The Mega-Guard Ship Automation System provides for (automatic) control of pumps, valves, heaters and other devices, the management of the electrical power plant, and the control for main engines and propeller. Control can be performed manually from the Workstation. This control can be part of automatic control sequences by the Mega-Guard series units according to specified conditions.3.1 Channel lay-out in a Mega-Guard systemChannels in a Mega-Guard system are represented as a 5 digit number UBBCC: U = Fieldbus Number (valid numbers: 1 to 4)BB = I/O Board Number (valid numbers: 1 to 96)CC = Channel Number on an I/O Board (valid numbers: 1 to 68)Channels are present on an I/O Board and on I/O Panel's. I/O Boards are used for physical I/O to ship's plant. I/O Panels are typically used as operator panels as applied in Generator Control and Main Engine Remote Control applications (lamps, pushbuttons etc.)Two type of channels can be distinguished:channels- Hardwarechannels- VirtualHardware channels are physically present and are connected to either a sensor, actuator lamp, pushbutton etc.. Virtual channels have the same functionality as hardware channels, but lack any physical I/O. They can be used for calculated input values, intermediate output results, alarming and logging purposes.3.2 Mega-Guard Alarm, Monitoring and Control functionsAlarm, Monitoring and Control functions are executed on Mega-Guard Control Processor level. Up to 4 I/O Boards can be connected to a single Control Processor. In addition, 1 I/O Panel can be connected to the Control Processor. I/O Boards also contain a LED indicator for each hardware channel with text window in order to indicate alarm or status conditions.This means that an Control Processor together with up to 4 I/O Boards and / or an I/O Panel acts as a stand-alone alarm, monitoring and control system.Control Processors are able to communicate with each other and to the I/O Server of a Workstation via a Fieldbus Network.3.3 Channel and tag numberingthe Workstation can be as follows:- use channel numbering (5 digit UBBCC; defined by used hardware)- use tag numbering (maximum of 10 digits; defined byowner/yard)With the Operator Keyboard or Trackball you can select (via general Page) if you want to display and print channel numbers or tag numbers. Only one method (channel or tag) can be displayed at the same time.3.4 Channel representation on Monitor, Printer and LOPThe monitor, Printer and LOP are used in the 110 character mode. One row consists of the following:Row part number of characters / digitsTag or channel number 10Time 8Description 40Value 7Engineering unit 5Limits (2 in total) 19Delay time 3Status 8On monitor the number of lines correspond to the following:Alarm and Diagnostic Page: 32 Alarm linesChannel Page: 30 Channel lines2 lines for channel / tag enteringGroup Page: 32 Channel lines1 lines for group headerInhibit and Skip Page: 32 channel linesFunctions3.5 Workstationinterface:• Operator- Process values and current status can be called on the Colour Graphic Monitor.Several process parameters can be grouped and called together.- System overviews, i.e. graphic presentations (mimic) of (part of) the system, showing conditions and values as changing symbols, colours and bar charts.- Manual control, like opening or closing a valve, can be performed with the Trackball.

This configuration can be setup using Ctrl K dialog, or in the Graphic Mimic Editor, where special key assignments per graphical page can be setup.4.4 TimeAt the top of each page the time is displayed as LT (Local Time) by default. It is possible to change this to UTC by clicking on the time (using the Trackball). The time associated with an alarm or event, which is displayed on the screen and printer, is referenced to LT. The selected time reference is shown at the top of the column 'TIME' of each page. The shown date is in accordance with this selection.4.5 Alarm and Acknowledge summaryNew alarms are presented in the following ways on the Workstation: - On the ALARM PAGE inserted at the top of the screen; STATUS field is flashingOn other pages; when the page contains a channel which goes into alarm condition; this is displayed in the STATUS field of the channel (flashing). - Blinking of ‘ALARM’ button at the bottom of each page. - On the Message Line at the bottom of each screen (STATUS field is flashing).Alarms can be acknowledged as follows:By selecting the Acknowledge function or when "Ack" is pressed on the Operator Keyboard4.6 PrinterAUTOMATIC ALARM PRINT FUNCTIONThe printer prints each channel getting in or out of alarm when the printer is configured for alarm printing. In case the printer is printing something else (e.g. PRINT SCREEN is pressed) and during the printing an alarm needs to be printed, the alarm is memorized and printed automatically after the PRINT SCREEN is finished. A return to normal is also printed when the alarm has already been acknowledged.AUTOMATIC PERIODIC PRINTINGAt pre-selected time intervals the periodic print-out starts. During this print-out, pre-selected pages of the system are printed. The pre-selections are made during SET-UP.DEMAND PRINTWhen this function is selected with the Trackball or Operator Keyboard, a print-out is made of pre-selected pages of the system.PRINT SCREENThe current screen contents are printed when this function is selected with the Trackball or Operator Keyboard. This function is mainly used when a print-out of a GRAPHIC MIMIC PAGE , GROUP PAGE or TREND PAGE is required.Each day at 00:00:00 the printer starts at a new page. The date is printed at the top of the page.4.7 AlarmPagePresents the channels, from all attached units, which are in alarm.4.7.1 Colour Graphic MonitorWhen ALARM PAGE is selected the following appears:Figure 3: Alarm PageIn this page only channels are presented which are currently in alarm or which have been in alarm but are not yet acknowledged. The channels are listed in chronological order. If the channels don't fit on one page, you can scroll through all available pages with the slide bar at the right side of the screen. You can also use the Page Up and Page Down or with Scroll-Up and Scroll Down on the Operator Keyboard.When a new alarm is detected the screen returns to the first page.The status position ('ALARM!') will blink when the channel gets into the alarm status. When the channel is acknowledged the blinking stops. Only the channels currently displayed are acknowledged with the Trackball or Operator Keyboard ('ACK' key or button resp.). Channels returning to normal disappear from the screen when they are acknowledged.The 'ALARM' page button also blinks in red as long as one or more channels are not acknowledged. It reverts to steady red when all alarms are acknowledged and back to grey when all alarms are resolved.4.7.2 Datalay-outThe channel data on the screen and on the printer is configured as follows:- channelreference- TAG- TIME - LTdescription- DESCRIPTION - channelvalue- VALUE - measurementnegativewhen• includingsign• including decimal point for smaller rangesisupdatedcontinuouslyvaluethe- UNIT - engineering unit (e.g. 'degC', 'Bar')- LIMITS - • one or two (or none) alarm limits: value (as above)and type ('VL', 'L', 'H', 'VH')• for an average alarm the corresponding averagevalue is shown instead- DT - alarm delay time in sec. (yellow) or min. (white/bold)- STATUS - current channel status (e.g. ALARM!, NORMAL,SENSFA).Status channels:When a channel is configured as a status input without the print status option on, the status changes are not displayed and printed in ALARM PAGE. In CHANNEL PAGE and GROUP PAGE the condition of a status channel can be monitored.Inhibition:The status of a channel whose inhibitor is active (i.e.: channel is inhibited) will not appear in the ALARM PAGE. When viewed from the GROUP PAGE or CHANNEL PAGE the channel's status is 'INHIB'.4.7.3 Alarm LoggingWhen enabled during SET-UP, all alarms and returns to normal after acknowledgement are logged to disk. A Comma Separated Variable (.CSV) file will be generated and logged to disk on a daily basis. The file is compatible and can be read by programs as EXCEL spreadsheet. Each day a new file is generated and the file name has the following lay-out:alarms_DDMMYYYY.CSV; Where:- YYYY = year numbermonth- MM =day- DD =Example file name:alarms_17072001.CSVThis file is stored in the sub directory "Data\AlarmLog" of the Mega-Guard folder, for instance:C:\Program Files\Praxis Automation Technology B.V.\Mega-Guard\Data\AlarmLog Since this folder is shared you can also find them by using the path:\\SERVER_1\Data\AlarmLogthat can be logged. See paragraph 4.8.2.4.8 Group Page, Trending and Data LoggingChannels of a predefined group (set-up) can be monitored.page4.8.1 GroupWhen GROUP PAGE is selected an overview page appears on the screen with all group numbers and the group descriptions. When enabled during SET-UP, a group number has 2 additional fields: Enable/Disable Logging and Trend View.When a group number is selected, the following appears on the screen:Figure 4: Group PageThe group message appears after the group number.If a channel is temporarily skipped the status field shows *SKIP*.When accessed via the General Selection Button 'GROUP' or the 'GROUP PAGE' key of the Operator Keyboard, PAGE UP / PAGE DOWN displays the next / previous group in the system. Scrolling within a group can be selected by moving the slide bar on the right side of the screen or by pressing the SCROLL UP/DOWN keys on the Operator Keyboard. To select a different group directly, select GROUP PAGE again.At the Message Line the most recent unacknowledged alarm is displayed (if any).4.8.2 Data LoggingChannels can be logged and trended (see paragraph 4.8.3). There are maximum quota's that need to be taken into consideration:Samples Logging Trend Trend Disk space Disk spaceSec/SampleChannelsChannelsGroupsMB per dayMB per week1 107 10.115 10010 1014.010030 100010 10023.316460 300010 250*35.02453600 500010 250* 1.411- If 3000 channels must be logged - 1 minute interval time between the samples - Channel trending is required, so the channels are divided in 30 groups3000 * 0.7 / 60 = 35Mb per day.To turn on logging the GROUP PAGE is selected and an overview page appears on the screen with all group numbers and the group descriptions. When enabled during SET-UP, a group number has 2 additional fields: Enable/Disable Logging and Trend View.When the data logging for a specific group is enabled a Comma Separated Variable (.CSV) file will be generated and logged to disk on a daily basis. Programs as EXCEL spreadsheet can read the standard file format.Each day a new file is generated and the file name has the following lay-out: GGG_YYYYMMDD_RRR.CSV; Where: - GGG = group number - YYYY = year number - MM = month。
