Gunakan Router Bekas Sistem Kemanan Bank Dibobol 1 Triliun
Gunakan Router Bekas Sistem Kemanan Bank Dibobol 1 Triliun
Komposisi infrastruktur yang memadai diperlukan untuk menunjang aktifitas sebuah perusahaan. Apalagi untuk sebuah perusahaan jasa keuangan salah satunya adalah bank, hal ini tak bisa dianggap remeh. Perangkat yang dibutuhkan harus secanggih mungkin agak tak bisa dibobol.
Kerugian yang mencapai Rp1 triliun disebabkan oleh para hacker. Kasus yang terjadi pada bulan Februari lalu, para hacker berhasil masuk ke jaringan utama bank sentral Bangladesh melalui router murahan tersebut. Lalu mereka mengirimkan sejumlah uang ke beberapa rekening.
Aksi hacker bisa ketahuan oleh pihak bank gara-gara salah dalam pengejaan nama saat hendak mengirimkan uang, sehingga membuat aksi ini diketahui oleh pihak bank. Kabarnya, para peretas ini mentargetkan pencurian hingga senilai 1 miliar USD, namun karena diketahui oleh pihak bank, mereka hanya mampu mengambil 81 juta USD atau setara dengan Rp1 triliun.
Setelah dilacak, uang yang dicuri tersebut kabarnya dikirimkan ke beberapa rekening di Filipina yang rata-rata menuju ke tempat judi atau kasino. Hingga saat ini, sebagian uang tersebut kabarnya belum pulih dan masih dalam tahap penyeledikan.
Pakar keamanan bank dari berbagai negara pun mengatakan hal yang sama, dimana seharusnya bank ini setidaknya menggunakan perangkat router yang lebih terjamin dengan mengeluarkan uang yang tidak seberapa.

Archive Cisco Switch and Router Configs Using TFTP and Configuration Archive
Archive Cisco Switch and Router Configs Using TFTP and Configuration Archive
The worst time to realize you dont have a current backup of your switch or router is when that device is having issues or worst case dies and it is actually needed. For a great comprehensive list of Cisco IOS commands I recommend THIS BOOK. Its for Amazon Kindle.
Administrators have the ability to run a manual backup of the configs or you can set it to do this automatically or every time you do a "write memory" to save a config change.
Given how easy this is to setup theres no reason for you not to have this on your switches.
Lets dive into how easy this is to setup.
First youll need a good TFTP server program. Personally I like the free Solarwinds TFTP Server. This like is for the Windows version. You can run it on a server or a workstation if needed. The price is right, setup is simple, and youll have this going in a couple of minutes.
Next its time to setup the switch or router to do the automatic backups for you.
Lets look at a couple of way to set this up.
The first way is to just backup each time you do a "write memory". This is my favorite setup as it does not generate unnecessary network traffic and I know that the files on my TFTP server are the latest config as long as they were saved.
R1(config)#archive R1(config-archive)#path tftp://192.168.1.10/R1-config R1(config-archive)#write-memory R1(config-archive)#exit |
Now one of the details I add after the IP address and forward slash is the name of the device so when it creates the automatic backup file I know which device it came from based on the devices host name.
Another way to set this up is to do backups daily for you automatically without the need to a manual update. This setup will archive every day or if you do a "write memory" command on the switch.
R1(config)#archive R1(config-archive)#path tftp://192.168.1.10/R1-config R1(config-archive)#write-memory R1(config-archive)#time-period 1440 |
Now these two methods ensure your switch configs are backed up either as you do a change and save it or automatically each day.
Finally the great thing about these auto backups is you can also restore them using the same functions. One thing to note is that this command does not merge the settings with what is currently running, it fully replaces it so use caution.
