Kumbuyuutarrada dadweynaha waa kuwa ay isticmaalaan wax ka badan hal isticmaale oo aan inta badan ka tirsanayn isticmaaluhu. Tusaale kombuyuutarrada dad waynaha waa kuwa ku yaal Maqaayadaha Internetka^{(Internet Cafes)} . Xataa kombayutarada xafiiskaaga waxa loo kala saari karaa sida kombayutarada guud maadaama aanad ahayn qofka kaliya ee isticmaalaya, inkasta oo laga yaabo inaad haysato aqoonsigaaga soo gelida. Waa inaad badbaado ku ahaataa markaad isticmaalayso kombayutarada dad waynaha sababtoo ah khalad yar waxa lagayaba in la jabsado akoonnadaada ama xogtaada la xado. Waa kuwan qaar ka mid ah talooyinka aad ku ilaalin karto kombuyuutarrada dadweynaha.

Sida looga badbaado kombayutarada dad waynaha

Markaad ku jirto kombayutarada dadweynaha, ma garanaysid waxa software ku rakiban mishiinka. In kastoo aad ka dhex baadho karto faylasha barnaamijka, waxaa laga yaabaa in lagu rakibo spyware ama keyloggers. Haddii milkiilaha Internet Café uusan damiir lahayn, wuxuu rakibi karaa keylogger si uu u basaaso macaamiishiisa. Wuxuu akhrin karayey iimaylada lagu sheekeysto iyo xitaa xogta xasaasiga ah ee arrinkaas. Haddii ay tahay inaad isticmaashid, aad uga taxadar xogta aad direyso ee isticmaalka xad dhaafka ah ee mishiinadan iyo waxa Raadka Dijital ah ee^{(Digital Footprints)} aad ka tagayso. Waa kuwan qaar ka mid ah dhaqamada ay tahay in la raaco marka la isticmaalayo kombayutarada dadweynaha.

1. Si sax ah uga bax

In ka badan inta badan, waxaan si fudud u xiraa daaqadda ka baxsan caadada. Qofka ku xiga ee ku dhaca inuu furo URL/site waxa si toos ah loogu jihayn doonaa akoonkaaga – wax kastoo ay tahay. Markaa, waxaad gebi ahaanba ku tiirsan tahay naxariista qofka galay akoonkaaga. Waxaa jira fursado badan oo uu qofku ku khaldami karo akoonkaaga - xisaabaadka bulshada, ganacsiga, ama xafiiska.

Had iyo jeer xasuuso inaad si sax ah uga baxdid ka dib marka uu casharku dhamaado. Haddii aad isticmaalayso Facebook , tusaale ahaan, eeg in badhanka Xusuustayda^{(Remember Me)} aan la hubin. Dhowr goobood ayaa leh badhamadan. Hubi in aan la hubin ka hor intaanad soo gelin. Kulanka ka dib, bax oo xidh daaqadda.

2. Ha ku kaydin macluumaadka diskka deegaanka

Isticmaal qalinkaaga si aad u soo dejiso faylasha macluumaadka aad rabto. Waa inaadan waligaa wax ku soo dejin Hard disk-ga deegaanka marka aad ku jirto kombayutarada dadweynaha. Waxa aad uga sii daran in wax lagu soo dejiyo kombayutaradan oo kale waa in la iloobo in la iska saaro ka hor inta aanad dhoofin. Xitaa haddii aad tirtirto, waxay ku soo degi doonaan qashin- qubka^{(Recycle Bin)} dib-u-warshadaynta oo si fudud ayaa dib loo soo ceshan karaa. Xitaa haddii aad faaruqiso dib-u- warshadeynta bin^{(Recycle Bin)} , mar walba waxaa jira siyaabo uu qofku ku soo ceshan karo faylasha la tirtiray.

Had iyo jeer qaado darawal qalin marka aad isticmaalayso kombayutarada dadweynaha. Haddii aad u baahan tahay inaad soo dejiso xogta ama faylalka macluumaadka, ku keydi wadida qalinka oo waligaa ha saarin Hard Disk-yada deegaanka. Haddii kale, haddii ay tahay inaad kaydiso macluumaadka iyo haddii aanad haysanin darawal, waxaad u diri kartaa email ahaan inay ku lifaaqan yihiin aqoonsigaaga iimaylka si aad dib ugu soo noqoto. Kadib markaad dirto iimaylka, tirtir faylashaas macluumaadka aad ku kaydisay saxanka deegaanka.

Haddii ay dhacdo in aad wax kasta ku soo dejiso disk-ga deegaanka, oo aad illowday in aad heshid qalinkaaga, iska hubi in aad tirtirtay dhammaan faylalkaas oo aad faarujisay qashinka dib-u- warshadaynta^{(Recycle Bin)} , si aad u sheegto ugu yaraan.

3. Tirtir raadadka wax baarista

Waxa jira InPrivate ama qaab qarsoodi^{(InPrivate or Incognito mode in browsers)} ah browser-yada kuwaas oo hubiya in aan waxba lagu kaydin saxannada deegaanka. Waxa aad isticmaali kartaa marka aad ka baadhayso interneedka^(Internet) . Habkaas, ma jiro taariikhda URL^(URLs) -yada aad booqatay sidoo kale wax cookies ah laguma kaydin doono qalabka deegaanka ka dib markaad xidho browserka. Haddii aad illowday isticmaalka habka qarsoodiga^(Incognito) ah, waxaad tirtiri kartaa taariikhda wax raadinta shakhsi ahaan adiga oo isticmaalaya ikhtiyaarka Aaladaha ee browserka. ^(Tools)Dhammaan daalacayaashu waxay leeyihiin meel awood kuu siinaysa inaad tirtirto taariikhda wax baadhista iyo cookies-ka. Dadka isticmaalaya isla kombuyuutar adiga dabadaa, ma sheegi karaan waxaad samaynaysay.

Habka kale ee wanaagsan waa in aad isticmaasho browser^{(portable browser)} -kaaga la qaadi karo ee qalinka ah. Waxaa jira qaar ka mid ah daalacashada la qaadi karo oo wanaagsan sida TOR ( The basasha Router^{(The Onion Router)} ). In kasta oo ay yara gaabis tahay, haddana kama tagi doonto wax raad ah oo ku saabsan waxaad ka samaynaysay internetka^(Internet) .

Haddii aysan ahayn isku xirka fiilada, laakiin WiFi , waxaad ku jirtaa khatar weyn, maadaama khatarta isticmaalka WiFi dadweyne ama bilaash ah^{(dangers of using a Public or Free WiFi)} ay aad u badan yihiin. Waxaad u baahan tahay inaad si aad ah uga ilaaliso naftaada hackers-ka kuwaas oo afduubi kara isku xirka xogtaada si ay u ogaadaan waxaad samaynayso. Waxa kaliya ee ay u baahan yihiin waa qalab fudud oo si fudud looga heli karo internetka^(Internet) iyo meelo kale. Akhri maqaalkeena ku saabsan sida loo ilaaliyo ammaan markaad ku jirto WiFi-ga dadweynaha^{(how to stay safe when on public WiFi)} .

4. Xogta Xasaasi ah

Kuma talin lahaa wax ku iibsashada kombayutarada dad waynaha maadaama aanad garanayn waxa kumbiyuutarku qabsanayo oo dhan. Sidoo kale^(Likewise) , ha dirin wax xog xasaasi ah adigoo isticmaalaya kombayutarada dadweynaha. Way fiicnaan lahayd in hore loo sii diyaariyo faylalka xogta kombayutarka gaarka ah ka dibna si toos ah loogu soo diro lifaaq ahaan si looga fogaado wax kasta oo keyloggers ah. Qaab kale ayaa ah in macluumaadka lagu qoro gacanta, in lagu sawiro makhaayadda, oo lagu soo diro iimaylka si lifaaq ahaan ah.

Ma jirto wax dammaanad qaad ah in kombayutarka dadweynaha aad isticmaalayso uu gebi ahaanba nadiif yahay sida lagu sheegay bilawga maqaalka. Waa inaad aad uga taxadirtaa waxa aad wadaagayso marka aad ku shaqaynayso kombayutarka guud.

5. Ka fogow in lagugu tufo

Snooping waxa la samayn karaa marka aad ka tagto kombayutarka dadweynaha oo furan qiiq ama wax kale. Ama waxay noqon kartaa qof kaa dambeeya. Haddii aad dareento in qof uu eegayo garbahaaga, taabo WinKey+D si aad u qariso dhammaan daaqadaha oo aad u muujiso desktop-ka. Markaad ka baxayso kombayutarka si degdeg ah, ha ilaawin inaad quful adigoo riixaya WinKey+L .

Hubi^(Make) in ay leedahay ilaalinta erayga sirta ah adiga oo dhaqaajinaya jiirka ama ku dhufanaysa barta bannaan si aad u furto. Waxaad mar walba waydiisan kartaa mulkiilaha kafateeriyada inuu kuu qoro erayga sirta ah. Fikradda ugu fiican waa in la xiro dhammaan daaqadaha firfircoon iyo nadiifinta taariikhda baarista ka hor intaadan ka tagin kumbuyuutarka xitaa si ku meel gaar ah. Ka tag kombuyutarka qeybta dhexe kaliya haddii ay aad muhiim u tahay.

Tips on how to stay safe on public computers

Public computers are the ones that аre used by more than one user and do not often belong to the user. An example of public compυters are the ones at Internet Cafes. Eνen computerѕ at your offіce can be categorized as public computеrs as you are not the only person using them, although you may have your оwn login credentials. You have to stay safe when using public computers because a slight mistake might result in the hacking of your accоunts or data being stolen. Here are some tips to stay safe on public cоmputers.

How  to stay safe on public computers

When on public computers, you do not know what software is installed on the machine. Though you can browse through the program files, there may be spyware or keyloggers installed. If the owner of the Internet Café is unscrupulous, he could install a keylogger to spy on his customers. He could read chats emails and even sensitive data for that matter. If you have to use them, be very careful about what data you are sending overusing those machines and what Digital Footprints you are leaving behind. Here are some of the must-follow practices while using public computers.

1. Log out Properly

More than often, we simply close the window out of habit. The next person who happens to open the URL/site will automatically be directed to your account – whatever it is. Then, you are totally dependent on the mercy of the person who accessed your account. There are high chances of the person messing up with your account – social, commercial, or office accounts.

Always remember to log out properly after the session is over. If you are using Facebook, for example, see that the Remember Me button is not checked. Several sites have such buttons. Make sure it is unchecked before logging in. After the session, log out and close the window.

2. Do not save information to local disk

Use your own pen drive to download the information files you want. You should never download anything to the local hard disk when on public computers. Much worse than downloading anything to such computers is forgetting to remove them before walking away. Even if you do delete them, they will land in the Recycle Bin and would be easily retrievable. And even if you do empty the Recycle Bin, there are always ways one can retrieve the deleted files.

Always carry a pen drive when going to use public computers. If you need to download data or information files, save them to the pen drive and never on the local hard disks. Alternatively, if you have to store information and if you do not have a pen drive, you can email them as attachments to your own email ID so that you can get back to them later. And after sending the email, delete those information files that you saved to the local disk.

In the eventuality that you have to download anything to the local disk, and you have forgotten to get your own pen drive, make sure you have deleted all those files and emptied the Recycle Bin, to say the least.

3. Delete browsing tracks

There is InPrivate or Incognito mode in browsers that makes sure nothing is stored on local disks. You can use it while browsing the Internet. That way, no history of URLs you visited nor will any cookies being stored on the local device after you close the browser. If you forgot to use Incognito mode, you may delete the browsing history personally using the Tools option in the browser. All browsers have a setting that enables you to delete the browsing history and cookies. People using the same computer after you, cannot tell what you were doing.

Another good method is to use your own portable browser on a pen drive. There are some good portable browsers such as TOR (The Onion Router). Though a bit slow, it won’t leave any tracks of what you were doing on the Internet.

If it is not a wired connection, but WiFi, you are at greater risk, as the dangers of using a Public or Free WiFi are much higher. You need to protect yourself much more against hackers who may hijack your data connections to know what you are doing. All they need is a simple device that is easily available on the Internet and elsewhere. Read our article on how to stay safe when on public WiFi.

4. Sensitive Data

I would not recommend shopping on public computers as you do not know what all things the computer is capturing. Likewise, do not send any sensitive data using public computers. It would be better to prepare the data files beforehand on a personal computer and then send it directly as an attachment to avoid any keyloggers. Another method is to write the information using hand, getting it scanned at the café, and sending it over with an email as an attachment.

There is no guarantee that the public computer you are using is totally clean as mentioned in the beginning of the article. You have to be very careful about what you are sharing when working on a public computer.

5. Avoid being snooped on

Snooping can be done when you left the public computer unlocked for a smoke or something else. Or it can be someone who is standing behind you. If you sense someone is looking over your shoulders, press WinKey+D to hide all the windows and show the desktop. When you are leaving a computer momentarily, do not forget to lock it by pressing WinKey+L.

Make sure it has password protection by moving the mouse or hitting the spacebar to unlock. You can always ask the café owner to type in the password for you. The best idea is to close all the active windows and clear browsing history before you leave the computer even temporarily. Leave the computer mid-session only if it is too necessary.
