Ancaman Spyware & Adware

AWAL

Kata spyware tentunya memancing reaksi spontan dari hamper semua orang yang
pernah surfing di Internet. Iklan pop-up, system yang tiba-tiba melambat,
icon aneh yang tiba-tiba saja muncul di desktop, drop-down menu yang hilang
atau tidak bias diakses adalah beberapa gejala yang diasosiasikan dengan
spyware. Gangguan ini bias melebar ke aktivitas yang lebih merugikan seperti
pencurian user id dan password, nomor kartu kredit yang terekam di computer.

DEFINISI SPYWARE & ADWARE

Spyware: program yang mampu memonitor aktivitas di suatu computer dan
mencuri informasi untuk dikirim ke computer induk di suatu lokasi (host) di
cyberspace. Informasi yang biasa dicuri adalah user id, password, nomor
kartu kredit, dokumen. Spyware juga menarget informasi seperti kebiasaan
browsing si empunya computer, program ter-install di computer, dll.

Spyware beroperasi secara sembunyi-sembunyi supaya tidak terdeteksi
kehadirannya. Sumber utama spyware adalah melalui download file shareware
atau freeware (program gratisan), email attachment, dan instant messages
(Yahoo Messenger atau MS Messenger). Beberapa instalasi spyware teraktivasi
melalui dialog End User License Agreement yang berbelit-belit dan sengaja
dibuat sangat panjang dengan kata-kata yang rancu (misleading).

Adware: program yang bertujuan menyampaikan iklan melalui interface sendiri.
Adware umumnya mengumpulkan informasi mengenai kebiasaan surfing dan
kebiasaan belanja online si empunya computer. Sumber adware sama dengan
spyware.

DAMPAK UTAMA SPYWARE & ADWARE

Dampak utama adalah system yang melambat, sering crash, koneksi network yang
lambat. Semua ini berakibat terbuangnya dengan percuma waktu IT department
yang berusaha untuk mengatasi gejala diatas. Dari sisi end-user tentunya
juga sangat merugikan karena menghambat pekerjaan dan mengakibatkan
frustrasi. Dari sisi perusahaan tentunya akan sangat merugikan karena
turunnya produktivitas karyawan, dan lebih lagi bila data-data yang bersifat
rahasia dicuri dan menyebar di internet.

KESIMPULAN

Zaman sekarang semua organisasi menghadapi problema diatas tanpa terkecuali.
Kebutuhan untuk suatu solusi security yang bias mengamankan dan melindungi
system IT sudah tidak bias ditawar lagi. Semua ini seperti memasang pagar
pengaman dan menyewa satpam yang professional.

Write more, thats all I have to say. Literally, it seems as though you
relied on the video to make your point. You clearly know what
youre talking about, why throw away your intelligence on
just posting videos to your blog when you could be giving us something enlightening to
read?

Hey! I know this is kind of off-topic but I had to ask.
Does building a well-established website like yours require a
large amount of work? I'm completely new to running a blog however I do write in my diary daily. I'd like to start a blog so I will be able to share
my personal experience and thoughts online. Please let me
know if you have any kind of ideas or tips for new aspiring bloggers.
Appreciate it!
