Maamulayaasha shabakadaha iyo xitaa kombuyuutarrada goonida ah ayaa had iyo jeer ka walaacsan amniga. Waxay isku dayaan inay hirgeliyaan qorshayaasha dhammaan khataraha suurtagalka ah ee ku wajahan amniga shabakadda oo ay ka fikiri karaan. Markay sidaas samaynayaan, waxay inta badan illoobaan qaar ka mid ah khataraha aasaasiga ah.

Khatarta Amniga Shabakadda

Maqaalkani waxa uu taxayaa shan khataro oo aan caan ahayn oo ku wajahan amniga shabakada.

1] Isticmaalayaasha Shabakadda^(Network) ama Nidaamyada Kaligii-jooga

Habka isticmaalayaasha shabakadu u adeegsadaan kumbuyuutarrada ayaa ah mid ka mid ah khataraha ugu badan ee la ilduufo. Isticmaalayaashu waa kuwa wakhtiga ugu badan ku bixiya kombuyuutarrada shabakada. Xitaa haddii kombuyuutarku leeyahay dekeddo kala duwan, haddii isticmaaluhu uu keeno qallinka jirran, dhammaan tallaabooyinka ammaanku way guul-darraystaan. Xaaladaha qaarkood, isticmaaluhu waxa laga yaabaa inuu ku xidhmo shabakada oo uu ka tago kumbiyuutarka keligiis dhowr daqiiqo. Daqiiqadahan yar waxay caddayn karaan qaali haddii qof kale go'aansado inuu eego xogta macluumaadka.

Habka kaliya ee lagula dagaallami karo dayacyadan waa in la baro isticmaalayaasha. Sidoo kale, ha ahaado kombuyuutar gooni u goosad ah ama kombuyuutar ku jira shabakadda, isticmaalayaashu waa in laga dhigaa mas'uul ka ah dhibaatooyinka dhacaya dayacaad.

2] Waa ayo^(Who) Qofkaas ku ^(VPN)Xidha^{(Person Connecting)} VPN ?

VPN- yadu^(VPNs) waxay noqon karaan khatar maadaama ay dadka u oggolaadaan inay meel fog ku xidhmaan shabakadda shirkadda. Halka xaaladaha qaarkood, ururadu ay bixiyaan laptops habaysan VPN^(VPNs) -yada , xaaladaha kale dadku way sii socon karaan oo ay abuuri karaan isku xirka VPN . Tan dambe waxay higaadin kartaa halaag haddii aan lala socon. Marka laga reebo ujeeddada qofka, la'aanta taxaddarrada habboon ee amniga ayaa hoos u dhigi karta shabakadda.

Si looga fogaado dhibaatooyinka VPN^(VPNs) -yada , waxaa lagu talinayaa inaad sameyso liiska mashiinnada idman oo u ogolow kaliya mishiinadan inay ku xidhmaan VPN -yada . Waxa kale oo aad samayn kartaa hanti-dhawr si aad u hubiso kuwa dhammaan ku xidhaya shabakada adoo isticmaalaya mashiinada iyo sababta.

3] Codsiyada duugoobay waa masuuliyad

Shabakadaha qaarkood, waxay sii wadaan adeegsiga noocii hore ee codsiyada (tusaale, Outlook Express ) rabitaan la'aanta inay ku bixiyaan casriyaynta. Kharashka halkan waxaa loola jeedaa lacagta iyo waqtiga labadaba. Codsiyada qadiimka ah waxaa laga yaabaa inay si fudud ugu shaqeeyaan kombayutarkaada/shabakaddaada, laakiin waxay khatar ku yihiin dareen ah inay si fudud ula wareegi karaan dadka xaasidiinta ah ee ka shaqeeya shabakada. Codsiyada dhaxalka qadiimka ah sidoo kale waxay u janjeeraan inay burburaan in ka badan marka loo eego noocyada cusub.

Waxaa lagugula talinayaa inaad hubiso qiimaha cusboonaysiinta. Haddii ay caadi tahay, cusboonaysii ama haddii kale u guuri arji cusub oo dhammaystiran oo la mid ah. Tusaale ahaan, haddii aad wali isticmaalayso codsiyada nooca " FoxPro for DOS", waxaa laga yaabaa inaad rabto inaad u guurto Visual FoxPro si aad u hubiso in barnaamijyadaagu hadda yihiin kuwo ammaan lagu rakibay.

4] Server-yadii Hore Oo Ku^{(Old Servers Running)} Wado Barnaamij Aan Macquul Ahayn

Ku dhowaad dhammaan shabakadaha waxay leeyihiin hal ama in ka badan oo adeegayaal ah oo ku shaqeeya barnaamijyo hore ama nidaamyada hawlgalka. Serfaradan lama cusboonaysiin karo maadaama taageeradu aanay hadda jirin. Adeegayaashan oo kale inkasta oo ay u muuqdaan inay si fiican u shaqaynayaan, haddana waxay khatar weyn ku yihiin shabakadda. Waad og tahay in server-ku aanu jabi doonin. Laakin waxaa hubaal ah in lagu afduubi karo indhaha shabkada.

Habka ugu fiican ayaa ah in la farsameeyo barnaamijyada ay ku shaqeeyaan server-yadii hore. Sidan, waxaad isku dayi kartaa oo aad cusboonaysiin kartaa barnaamijyada. Taas beddelkeeda, waad daadin kartaa barnaamijka oo dhan oo aad bedeli kartaa.

5] Maamulayaasha Maxaliga ahi had iyo jeer waa khatar

In ka badan inta badan, maamulayaasha maxalliga ah ayaa ah dadka la siiyo mudnaan gaar ah oo kaliya inay cilad ku sameeyaan shay kumbuyuutarka. Marka cilad-baadhistu dhammaato, mudnaanta maamulka waa in lagala noqdaa laakiin dadka IT-ga way iloobaan inay sidaas sameeyaan. Xaaladdan oo kale, koontada isticmaalaha maamulka deegaanka ayaa ku martiqaadi doona mashaakil hal ama maalin kale. Habka ugu fiican ee lagula tacaali karo maamulayaasha maxalliga ah waa in la abuuro profiles si iskiis u dhaca.

Kuwani waxay ahaayeen shan khatarood oo aan caan ahayn oo ku wajahan amniga shabakadda, fikradayda. Haddii aad rabto inaad ku darto ama aad dareento inaan wax seegay, fadlan ku dhaaf qoraal hoos.^{(These were five lesser-known threats to network security, in my opinion.

Lesser known Network Security Threats that Admins should be aware of

Administrators of netwоrks and even standalonе сomputers are always concerned about security. They try to implement plans for аll the possible threаts to netwоrk security that they can think of. In doing so, thеy often forget some of the very basic threats.

Network Security Threats

This article lists five lesser-known threats to network security.

1] Users Of The Network or Stand-Alone Systems

The way users of the network use the computers is one of the most overlooked threats. Users are the ones who spend the most time on the computers on a network. Even if your computer has a firewall at different ports, if a user brings an infected pen drive, all security measures fail. In some cases, the user may connect to the network and leave the computer alone for few minutes. These few minutes can prove costly if someone else decides to take a look at the database.

The only method to fight these neglects is to educate the users. Also, be it a standalone computer or a computer on the network, users should be made responsible for problems occurring out of neglect.

2] Who Is That Person Connecting Through VPN?

VPNs can be a danger as they allow people to connect remotely to the corporate network. While in some cases, organizations provide configured laptops for VPNs, in other cases people might just go ahead and create a VPN connection. The latter can spell doom if not monitored. Other than the person’s intentions, lack of proper security precautions may bring down the network.

To avoid problems with VPNs, it is suggested that you make a list of authorized machines and allow only these machines to connect via VPN. You can also set up an audit to check who all are connecting to the network using what machines and why.

3] Outdated Applications Are A Liability

In some networks, they continue using an older version of applications (for example, Outlook Express) for unwillingness to spend on the upgrades. Spending here refers to both money and time. Older applications may be running easily on your computer/network, but they are a threat in a sense that they can easily be taken over by malicious people on/off the network. Older legacy applications also tend to break down more compared to newer versions.

It is recommended that you check out the cost of the upgrade. If it is okay, upgrade or else move to an entirely new application with similar functionality. For example, if you are still using “FoxPro for DOS” type applications, you might want to move to Visual FoxPro to make sure your programs are current with security installed.

4] Old Servers Running An Impossible Program

Almost all networks have one or more servers that run older programs or operating systems. These servers cannot be updated as support is no longer available. Such servers though appear to be working fine, are a big risk to the network. You know that the server won’t break down. But it sure can be hijacked by prying eyes on the network.

The best method is to virtualize the programs that the ancient servers are running. This way, you can try and upgrade the programs. Alternatively, you can shed the entire program and go for a replacement.

5] Local Administrators Are Always A Threat

More than often, local admins are the people given special privileges just to troubleshoot something on the computer. Once the troubleshooting is over, admin privileges should be revoked but the IT people forget to do so. In such a case, the local admin user account will invite problems one or the other day. The best method to deal with local admins is to create profiles that auto-expire.
