It's almost like those too-familiar infomercials that get so popular around New Year's - time to get rid of the fat and add some muscle. Cisco's done the same to CCNP with today's announcement of CCNP changes. Cisco starts by removing roughly half the topic breadth from the old CCNP: most every topic from ONT and ISCW is gone. Cisco then adds back a Troubleshooting exam that focuses on routing and switching with a few other topics. Today I'll begin an examination of this revised cert, with lots of links, some impressions, and a promise to more time in the coming weeks drilling down on the new exams.
For a bit of historical perspective can be useful to frame this change. From its inception in 1998, CCNP has included a 4-exam path. Additionally, Cisco has normally also offered a composite exam that covered the same topics as either 2 or 3 exams, just to reduce the overall time and cost. However, from a breadth perspective, CCNP has always covered topics that matched 4 authorized Cisco courses of 5 days in length. So, the breadth was basically what you could learn in class in 20 days of classroom learning.
The first few iterations of CCNP included a Troubleshooting exam, which matched a T'shooting course. With the last big change to CCNP before now - 2006 I believe - Cisco really changed things up a bit. Gone was T'shooting. Cisco changed CCNP to reflect the fact that route/switch engineers were more often route/switch/security/QoS/Wireless engineers, with much broader job roles. With the 2006 changes, in came ISCW (mostly security, VPNs, Internet access, MPLS) and ONT (mostly QoS and Wireless). But CCNP was still four 5-day courses, still same relative effort based if compared to the number of days in the authorized courses, but a much wider range of topics.
So, back to the present. Roughly 4 years after the widening of CCNP, Cisco makes a

Teknologi yang digunakan para penjahat cyber semakin lama juga semakin canggih. Tak ayal, pihak perbankan pun harus memiliki sistem keamanan yang kuat untuk menghadangnya.
Meski demikian, untuk terhindar dari tindak kriminal ini juga diperlukan peran aktif nasabah. Simak 6 kiat untuk menghalau aksi pembobolan rekening ini menurut M. Salahuddien, Wakil Ketua Indonesia Security Incident Responses Team on Internet Infrastructure (ID-SIRTII):
1. Gunakan hanya kartu chip, kalau bank Anda belum memberikan kartu chip, Anda harus minta ganti dan jangan menggunakan untuk transaksi sebelum diganti. Aturan Bank Indonesia (BI) yang baru, sejak Januari 2010 kartu yang resmi dan boleh digunakan hanya kartu jenis chip.
“Cuma saya belum konfirmasi apakah aturan ini untuk kartu kredit saja atau juga untuk kartu atm? Seharusnya semua kartu yang diterbitkan perbankan. kalau di luar negeri, mesin ATM sudah tidak mau menerima kartu non-chip,” papar Didin, panggilannya.
2. Lindungi kode 3 angka (CVV2) di belakang kartu Anda. Kecuali untuk otorisasi transaksi online, kode itu tidak akan pernah digunakan untuk transaksi konvensional di mesin ATM, atau di counter EDC merchant. Tutup 3 angka di belakang kartu itu dengan sticker, cellotape apa saja yang tidak transparan
3. Ubah PIN Anda sesering mungkin. Parameternya sederhana, ketika Anda cukur rambut, ganti kaos kaki (karena mulai bau), atau ganti sikat gigi (karena sudah mulai kusut) atau setiap kali cek angin ban kendaraan, itulah saatnya mengganti PIN kartu ATM Anda. Misalnya di pom bensin, biasanya sekarang ada mesin ATM, Anda bisa mengganti PIN ketika sedang transaksi pembelian BBM.
“Itu serius, musuh utama masalah keamanan adalah behaviour manusia itu sendiri, kebiasaan, kelakuan, sebagian besar pembobolan terjadi akibat dari eksploitasi terhadap kelemahan sosial, makanya disebut social engineering,” tukasnya.
4. Jangan pernah memberikan informasi pin dan data pribadi yang biasa digunakan untuk otorisasi perbankan kepada siapapun dengan alasan apapun termasuk pada customer service bank, seperti misalnya nama

Santa lives at the North Pole.
JESUS is everywhere .
Santa rides in a sleigh
JESUS rides on the wind and walks on the water.
Santa comes but once a year
JESUS is an ever present help.
Santa fills your stockings with goodies
JESUS supplies all your needs.
Santa comes down your chimney uninvited
JESUS stands at your door and knocks.. And then enters your heart.
You have to stand in line to see Santa
JESUS is as close as the mention of His name.
Santa lets you sit on his lap
JESUS lets you rest in His arms.
Santa doesn't know your name, all he can say is "Hi little boy or girl, What's your name?"

Using Cisco NBAR to monitor Traffic Protocols on your Network |

Many network administrators already know how to use tools like Cacti or MRTG to monitor the usage on their network links. (If you don’t, let me know and I’ll show you how.) Unfortunately, those tools only reveal part of the story. They show you how much traffic is traversing a link, but not what kind of traffic is traversing a link. The difference may not be that important until your corporate DS3 is hitting 42 Mbps and you have no idea why.
What is NBAR?
According to Cisco:
NBAR is an intelligent classification engine in Cisco IOS Software that can recognize a wide variety of applications, including Web-based and client/server applications.
In layman’s terms, NBAR examines traffic on a designated router interface and makes note of what application the traffic is associated with. It does this by mapping traffic ports to protocols (i.e. 25/TCP is SMTP), but it also recognizes traffic with no standard port number like various P2P protocols. The primary purpose of NBAR is to recognize the traffic on an interface so that QoS policies can be applied to it. This is a big step forward compared to clunky ACLs which require exact protocol and port matching.
QoS? I just want to know what’s going on!
Nothing could be simpler. If you release of IOS supports NBAR, simply add the 'ip nbar protocol-discovery' configuration command to the interface that your users are using as their default gateway. For example:
SLAP#config t
Enter configuration commands, one per line. End with CNTL/Z.
SLAP(config)#interface FastEthernet0/0
SLAP(config-if)#ip nbar protocol-discovery
SLAP(config-if)#^Z
SLAP#wr
Building configuration...
[OK]
SLAP#
Once NBAR is gathering data, you can use the 'show ip nbar resources' command to see how much memory it’s taking up. As long as the numbers are acceptable, you can leave NBAR protocol discovery running as long as you like. To see the really interesting information, issue 'show ip nbar protocol-discover' and look at all the protocols flowing to (and perhaps through) your router. In the screenshot to the right, you can see that I’ve limited the output by using the 'top-n' variant of the above command. |

Gila! Jepang Lampaui Kecepatan Internet 32 Miliar Kbps |

Copied from Detik:
Jakarta - Sebuah teknologi optik baru sedang diujicoba di Jepang. Dahsyatnya, teknologi itu mampu mencapai kecepatan 30 Terabit per detik (Tbps) atau lebih dari 32 Miliar Kbps.
Uji coba itu telah dilakukan oleh KDDI R&D Labs bersama National Institute of Information and Communications Technology (NICT) di Jepang. Teknologi yang diujicoba memanfaatkan transmisi bernama OFDM alias orthogonal frequency division multiplex.
Sekadar pembanding, kecepatan koneksi internet saat ini masih jauh --sangat jauh-- dari yang dicapai dalam ujicoba tersebut. Kecepatan 500 kilobit per detik (Kbps), misalnya, sudah termasuk lumayan untuk penggunaan normal sehari-hari. Sedangkan rata-rata kecepatan internet di dunia, berdasarkan data akhir 2008, adalah 1.5 Mbps atau 1500 Kbps.
Nah, 30 Terabit per detik itu kurang lebih setara dengan 32 miliar kilobit per detik. Dengan kecepatan seperti ini, per detiknya data yang sanggup dikirimkan mencapai 3,9 juta MB, atau hampir 1.000 keping DVD film per detiknya.
Seperti dikutip detikINET dari Nikkei, Kamis (30/7/2009), ujicoba itu dilakukan pada jarak 240 kilometer, artinya bukan sekadar ujicoba jarak dekat. Rencananya KDDI akan mengkomersialkan teknologi ini pada 2012.
