The Introduction of the Vpn

Hallo friends we met again in this simple blog post. This time we'll have a little share information about VPN.

A virtual private network (VPN) extends a private network across a public network, such as the Internet. It enables a computer to send and receive data across shared or public networks as if it is directly connected to the private network, while benefiting from the functionality, security and management policies of the private network. A VPN is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual tunneling protocols, or traffic encryptions.

VPNs allow employees to securely access their company's intranet while traveling outside the office. Similarly, VPNs securely connect geographically disparate offices of an organization, creating one cohesive network. VPN technology is also used by Internet users to connect to proxy servers for the purpose of protecting personal identity and location.

Choosing a VPN

A VPN service’s main selling points are security and privacy, but privacy is interpreted differently among VPN providers. Just ask former lulzsec member Cody Kretsinger (a.k.a. recursion), how private his VPN service was.

Kretsinger used a popular VPN called HideMyAss and engaged in activity that linked him, and his online persona “recursion,” to several high profile hacks, including unauthorized access to servers controlled by Sony Pictures. As it turns out HMA keeps logs of users’ IP addresses and logon/off times. A UK court order was issued to HMA to turn over the logs related to the offending account, which were then used to identify and arrest Kretsinger.

VPN providers can log web activity over their network, but it is more common to see VPN providers log users’ IP addresses, logon/off times and bandwidth usage. This logging activity allows providers to identify individuals abusing the service for fraud and spam, but in doing so they acquire information that can be used to identify individual users.

You can be absolutely sure if a VPN provider is pressured to cooperate with authorities and they have any information to identify you as the suspect you will be up shit creek and you will be there without a paddle. No one is going to go to jail for you.

This is why some VPN services go out of their way NOT to log any information that could possibly identify their customers. They cannot be forced to hand over incriminating information that they do not have.

Why Trust In Your VPN Provider Is Important

Not all VPN service providers are worth your trust. Some diligently log your connection times, dates, IP addresses, keep track of how long you're connected, and some even keep an eye on the types of traffic that you send through their networks while you're logged in. They'll tell you it's in order to make sure you're not doing anything illegal, or anything that would damage their network, but that level of snooping does kind of go against the whole purpose of a VPN, doesn't it?

The best ones keep as few logs as possible, and aren't interested in what you do while you're connected at all. Some don't even track when you're logged in or out, and even if they do have to keep some logs, they purge them periodically in order to protect your privacy. After all, the reason you pay for a VPN is for privacy and security, and if they keep their own data, they're the weak link in that chain. Here's are some tips on how to research a VPN and decide whether they're a good match for you.

Read their Privacy Policy

It is mundane but it is so incredibly important when considering a VPN to read the company’s Terms of Service and the Privacy Policy, and these documents need to be in plain English not lawyer-eese. A VPN provider who legitimately cares about customers’ privacy will lay it out in black in white what information, if any, is recorded and for how long.

Good VPN providers state that they store “personal information” necessary to create an account and process a payment (for example: name, e-mail address, payment data, billing address), but state that they do NOT log users’ IP addresses, logon/off times, or bandwidth usage.

Great VPN providers go a step further to minimize the amount of “personal information” required by accepting bitcoin or other cryptocurrencies, eliminating the requirement for billing information. This further insulates the user’s true identity by requiring an as little information as an e-mail address to create an account.

An honorable mention must go out to VPN provider MULLVAD who do not even require an email address. Visitors to the website click “create account” and they are given an account number without entering any information at all.

Google their name and "logging" in the same query

It may sound simple, but it's actually really effective. You'll usually turn up the provider's own privacy policy (which, in the worst cases can be so buried it's difficult to find), which can answer the question right away. Some VPN providers are proud to say they don't keep logs, or that they only keep access logs in order to bill you for usage, or that they do log, but they purge daily or weekly. Some will try to dance around the issue by saying they keep "whatever logs are required by law," which really means whatever law enforcement has asked them for—which could be anything. Others won't address the issue at all—that's where the rest of the results come in. You'll probably find other sites and articles discussing the company's logging policies, which can help you figure out if they care about your privacy as much as they care about your security.

Bitcoin

With VPNs, the acceptance of bitcoins is also a critical factor. This gives you an indication of how seriously a VPN takes your privacy.

Don't be afraid to ask outright

If you don't get the answer you want from simple searches, contact them and ask what their logging and data retention policies are. Again, this is something you'd want to do with premium providers more than free ones—you don't want to spend your money unless you're sure what you're getting.

Beware US Based Providers

Faced with the sweeping powers afforded to government agencies (such as the NSA) by the post 9/11 Patriot Act, and to copyright enforcement bodies by legislation such as the Digital Millennium Copyright Act 1998 (DMCA), most US based VPN providers do not make any real pretence at protecting their customers privacy or identity.

A few, most prominently Private Internet Access, do claim to provide high levels of security by keeping no logs ‘whatsoever’, and by using shared IP addresses, which in theory makes identifying an individual user with any internet behaviour impossible. However, the following points should be considered:

    All US VPN companies are subject to the Patriot Act, and if the NSA is able to monitor all data collected by the likes of Google, Microsoft and Facebook, then it would be foolish to assume they cannot, or do not, monitor the servers of VPN companies such as PIA (who as we noted have a high profile).

    All VPN companies are subject to the Stored Communications Act (SCA) which can force a provider to keep logs on the activities named individuals without alerting them to the fact

    All VPN companies are subject to CALEA search warrants, which gives the FBI broad powers to conduct electronic surveillance by requiring that telecommunications carriers and manufacturers of telecommunications equipment modify and design their equipment, facilities, and services to ensure that they have built-in surveillance capabilities, allowing federal agencies to monitor all telephone, broadband internet, and VoIP traffic in real-time.

    All traffic that passes through the US communications backbone can be monitored, so any traffic that passes through a US server can, at least in theory, be monitored by the likes of the NSA. Although the contents of encrypted traffic will remain hidden, the NSA can collect metadata of a similar nature to that obtainable by ISPs.

The paranoid should therefore avoid any company even remotely related to the United States. However, we think that companies such as Private Internet Access are genuinely committed their customers’ privacy and anonymity, but have little faith in their ability to guarantee this on US soil. Using their overseas servers should be ok though, as US laws and organisations have neither the means nor jurisdiction to prevent logs from being discarded form servers outside the United States.

Cloud Computing Data Security

Cloud computing refers to the practice of transitioning computer services such as computation or data storage to multiple redundant offsite locations available on the Internet, which allows application software to be operated using internet-enabled devices.

Cloud Storage utilization impact resulting from the development of cloud computing is increasingly being utilized in the world. All States also have started to utilize cloud computing technology. This is supported by a growing network of internet the pervasive and increasingly cheap, as the community can enjoy this facility.

Cloud computing poses privacy concerns because the service provider can access the data that is on the cloud at any time. It could accidentally or deliberately alter or even delete information. Many cloud providers can share information with third parties if necessary for purposes of law and order even without a warrant. That is permitted in their privacy policies which users have to agree to before they start using cloud services. Solutions to privacy include policy and legislation as well as end users' choices for how data is stored. Users can encrypt data that is processed or stored within the cloud to prevent unauthorized access.

According to the Cloud Security Alliance, the top three threats in the cloud are "Insecure Interfaces and API's", "Data Loss & Leakage", and "Hardware Failure" which accounted for 29%, 25% and 10% of all cloud security outages respectively — together these form shared technology vulnerabilities. In a cloud provider platform being shared by different users there may be a possibility that information belonging to different customers resides on same data server. Therefore, Information leakage may arise by mistake when information for one customer is given to other. Additionally, Eugene Schultz, chief technology officer at Emagined Security, said that hackers are spending substantial time and effort looking for ways to penetrate the cloud. "There are some real Achilles' heels in the cloud infrastructure that are making big holes for the bad guys to get into". Because data from hundreds or thousands of companies can be stored on large cloud servers, hackers can theoretically gain control of huge stores of information through a single attack — a process he called "hyperjacking".

 

Cloud Storage provides ample storage media, here you can use it to store a wide range of purposes such as documents, presentations, photos, or videos. Not only from the hardware used, we can freely access the data in the cloud storage through other devices because applications now cloud has already spread in various operating systems of windows, linux, Cisco ios, and mobile. But do you know about data security in the cloud storage? below are a few key points lest our data that resides in the cloud storage secure & assured.

Data Protection

When we've decided for adoption or migration of data to the Cloud, that the note is how Cloud services providers provide protection against our data. By what method they do protectionism so that we are sure your data is safe, in addition to the data storage location is also an important consideration where this has to do with the Data Center. Certain data center they make certified/teraudit, for example, the location of the earthquake free, standard electrical resources 3 tier etc.

 

Security Control

After our data really protected, next is how the security of access to the data we (role), how the procedure so that only those who are entitled to access our data. Here, including the access of workers/employees at towards our data service providers.

Compliance

Standards that apply to providers of Cloud Computing Services, such as for data security using ISO 27001, for provision of the services wear ITIL, COBIT, Cloud Security Alliance, including international lawyers and Government Regulation. So if there are any violations would be easy in the completion

 

Multi-tenancy

One of the properties of Cloud computing is the resource sharing, well how when there is another tenant there is cheating or leaked, what effects against our data there, it should be considered. Because physically, our data could be there in one of the same physical media.

Security Governance

This is more to policy governance of service providers or us as a user of the services, should be spelled out and his governance paka what must be defined here.

 

The issue again warm is any outside electronic service provider must have data center, this is one government regulation related rules the data center. Same with us when you want to move the data to the Cloud, make sure that the data we have, because every country has its own way of doing and data and its own data center.

How to Remain Anonymous

Tor is a magical browsing piece of software. However it does have a few limitations and you should keep these in mind. Tor is primarily focused on protection of data being transported. You also should use protocol-specific software (support software) to ensure sites you are visiting do not see your identifying info. You can use Torbutton while browsing to hold certain information about the configuration of your computer.

The Tor Browser Bundle is what you should be using, and the new version of this bundle includes  Firefox latest edition, since the programmers at Torproject.org do not have the time to constantly update the Tor browser to keep up with Firefox accelerated release schedule of updates. Torproject.org at this time does not recommend using the “Toggle” model of torbutton. Users are recommended to use Tor Browser Bundle, they should not install Torbutton separately.

Do not enter personal information

Also keep in mind that there is nothing Tor can do to protect you from a site gathering information from you that you purposely enter. In other words if you voluntarily submit your personal data to a website, there is absolutely nothing Tor can do in that case. You have broken the privacy bond by doing this so please do not give out personal information on sites you surf in the Deep Web. Protect yourself.

Alternative Services or Methods Tor is not the only method available online for browsing security, and we all know that nothing is foolproof. There are also services that will enable you to maintain anonymity, albeit at a slightly less secure level, and let us explore a few of these options.

Proxies: Proxies are basically services where users access different IP addresses to log in under using what are called Proxy IP addresses. When users log in under proxy IP addresses, it appears to others that their location is actually the location where the IP address is being hosted. Many users use these proxy addresses and they do provide some level of anonymous surfing. However, these proxy address lists are passed around and well known to many internet companies and they can easily detect if you are logging on via a proxy address. Also, you have the option of purchasing a separate IP address for yourself, a personal proxy IP, and these are certainly not as well known, but they suffer from some of the same vulnerabilities that other proxy IP addresses suffer from.

Proxies are really not that secure, as they can easily be detected by one eavesdropping on your browsing activities. They are considered amateur and low level by most experienced browsers of the Deep Web and most would not browse using only a proxy IP.

VPN Services. VPN stands for Virtual Private Network. VPNs are private networks that many corporations use to maintain security especially for their financial transactions. They are more difficult to “sniff” (where intruders basically intercept data on the server) and they offer a higher level of security than Proxy IP addresses.

Policy on Privacy? If you want to maintain total anonymity, or certainly a higher level of anonymity, one fear that people have is a subpoena issued to a host, which demands the host to turn over your browsing activity information. Not all companies will do this, and some will flat out refuse to hand over the information. One company such as this is Cryptocloud and another company who refuses to hand over information is iPredator. So be sure and keep this in mind when you are choosing a VPN host, if you should choose to go that route.

Combination is safest. Many surfers on Tor, of course are using Tor, which is a first step in the process of anonymity. But many of them take the extra step and also log into Tor via a VPN network. This adds an additional layer of security and also makes it that much more difficult for any govt agency or any nosy person to spy on your browsing activities online.

Latest Software for the iPhone and Mac

 Apple announced its latest software for the iPhone and Mac at its annual Worldwide Developers Conference in San Francisco.
The next version of OS X, Apple' (AAPL, Tech30)desktop operating system, has a name: OS X El Capitan. Following a series of cats, Apple is naming new version of OS X after California landmarks.

Apple’s Craig Federighi said it was going to be the fastest version of OS X to date: “It’s up to 1.4x faster and we’ve seen it twice as snappy switching between apps.”
Apple has improved window management in El Capitan, including the ability to size windows to half the screen, something Microsoft’s Windows has had baked in for years but requires a third-party app such as Moom or manual rearrangement on Yosemite.
Federighi said the company had made many hundreds of small changes to the rest of Apple’s core apps, including Safari which can now pin tabs within the tab bar in the corner and can load instantly.

OS X El Capitan is available to developers today. A public beta will start in July, and it will be available to everyone in the fall.
"We honestly just don't want to know," said Federighi. "All of this is done on device and it stays on your device, under your control."

Siri Proactive. In iOS 9, the new software for the iPhone and iPad, Siri is getting a big update. Siri is going to attempt to guess what you want to know, before you ask it. Just like Google Now.
Apple's iOS smart assistant is getting an upgrade, called Siri Proactive, that includes predictive tools. It has smart reminders that know more about your location and habits. It pulls from your search history, emails and calendar to give smarter search results to surface information and suggest apps.
"This is all context sensitive to the time, the place and even the devices you're connected to," said Federighi.
Apple Pay. Square's next card reader will accept Apple Pay. Apple Pay will also be available to people in the United Kingdom starting in July, including support for public transit. Apple's Passbook app is being renamed Wallet, and will support retail loyalty cards.

IPad users can also get split screen apps and improved app switching and keyboard shortcuts. They might seem minor but small improvements like this push the iPad that much closer to being a serious word-processing device.
Homekit. Apple's hub for connected home devices, Homekit added iCloud access and controls for window and controls for window shades, thermostats, lights and sensors.
More power for iOS 9. With all those new improvements, Apple also had to address one of the biggest drags of running powerful tools on a mobile device: battery life.

Some Apple Macs have a particularly terrible flaw that lets hackers sneak in and remain undetected, a security researcher has found.
It means a hacker could -- from far away -- force a Mac into a coma. Personal, corporate or government Macs could be spied on in a way that even the best security checks wouldn't discover -- until it's way too late.
"This is scary," said Sarah Edwards, a forensic analyst at the SANS Institute who specializes in reviewing computers for evidence of hacks. "I would never see this. There could be funky stuff going on in the computer system, and I would never know why."
All computers have some kind of basic input/output system (BIOS), the core program that brings a machine to life. It's the kind of thing you should never tamper with. And it should obviously remain heavily guarded.
When a Mac goes into sleep mode and wakes back up, it allows direct access to the BIOS. It's a weird quirk that lets someone tamper with the code there. That's what was discovered recently by Pedro Vilaça, a curious independent computer security researcher in Portugal.

Several cybersecurity experts confirmed that this is a real problem, and they plan to research further in the next few weeks.
This isn't an easy hack. An attacker first needs administrative access to a machine. But what this means is that if a Mac gets hacked with a low-level computer virus, it can bury so deep you'll never find it.
That's the real problem here. It gives hackers more time to plot a massive bank heist or a huge corporate takedown, like the Sony Pictures hack.
The average Mac user doesn't have to worry about this one, because they're actually susceptible to cheaper, easier hacks -- that are easier to spot and fix. So says Katie Moussouris, an executive at HackerOne, which helps companies fix dangerous computer bugs.

Tod Beardsley, a security research manager at cybersecurity firm Rapid7, stressed that most Mac users aren't likely to get hacked because of this bug. He said the flaw is "certainly surprising ... but the bar of difficulty is pretty high."
This is the second major flaw in Apple devices discovered in the last week. Recently, people discovered that you can crash someone's iPhone simply by sending it a text message.
Vilaça decided not to name this bug. But every major computer flaw nowadays deserves a name. Given that it involves a poisonous kiss that wakes a sleeping Mac.

Protect you from data theft and illegal access to the iphone and mac os.
A cracker could penetrate the security gaps and weaknesses of every defect information from the program.
By updating the operating system a step further for you to protect from the cracker.

KOMPUTER

Kembali jumpa lagi dengan para blogger.

Ok bro, saatnya memposting tentang informasi komputer.

Siapkan saja kopi dan cemilan agar lebih asik membaca informasi dibawah ini.

Karena bacaan ringan ini semoga menambah pengetahuan kalian semuanya.

Kita mulai dari definis komputer.

 

Komputer biasanya berarti sebuah mesin yang diprogram. Dua karakteristik utama komputer: menanggapi serangkaian Instruksi spesifik dalam cara yang didefinisikan dengan baik dan itu dapat mengeksekusi direkam sebelumnya daftar instruksi (program).

 

Komputer adalah perangkat tujuan umum yang dapat diprogram untuk melaksanakan serangkaian operasi aritmatika atau logis secara otomatis. Sejak serangkaian operasi dapat mudah berubah, komputer dapat menyelesaikan lebih dari satu jenis masalah.

http://en.wikipedia.org/wiki/Computer

 

Semua komputer untuk keperluan umum memerlukan komponen-komponen perangkat keras yang berikut:

1. Memori: memungkinkan komputer untuk menyimpan, setidaknya untuk sementara, program dan data.

2. Perangkat penyimpanan massal: memungkinkan komputer untuk secara permanen menyimpan data dalam jumlah besar. Perangkat penyimpanan massal umum termasuk disk drive dan drive pita.

3. Perangkat input: biasanya keyboard dan mouse, perangkat input adalah saluran melalui mana data dan petunjuk masukkan komputer.

4. Perangkat output: layar, printer, atau perangkat lain yang memungkinkan Anda melihat apa yang komputer telah dicapai.

5. Unit pemroses Sentral (CPU): jantung komputer, ini merupakan komponen yang benar-benar mengeksekusi instruksi.

Selain komponen ini, banyak orang lain membuat mungkin untuk komponen dasar untuk bekerja sama secara efisien. Sebagai contoh, setiap komputer membutuhkan bus yang mentransmisikan data dari satu bagian dari komputer lain.

 

Komputer dapat umumnya diklasifikasikan oleh ukuran dan kekuasaan sebagai berikut, walaupun ada banyak tumpang tindih:

1. Komputer pribadi: komputer kecil, satu-user berdasarkan mikroprosesor. Selain mikroprosesor, komputer pribadi memiliki keyboard untuk memasukkan data, monitor untuk menampilkan informasi, dan perangkat penyimpanan untuk menyimpan data.

2.  Pengguna tunggal yang kuat, komputer workstation. Sebuah workstation adalah seperti komputer pribadi, tetapi memiliki lebih kuat mikroprosesor dan monitor kualitas yang lebih tinggi.

3. Komputer mini: multi-user komputer mampu mendukung dari 10 hingga ratusan pengguna secara bersamaan.

4. Kuat multi-user komputer mainframe mampu mendukung ratusan atau ribuan pengguna secara bersamaan.

5. Sangat cepat komputer superkomputer yang dapat melakukan ratusan jutaan instruksi per detik.

 

Ada penelitian yang aktif untuk membuat komputer dari banyak jenis baru yang menjanjikan teknologi, seperti komputer optik, DNA komputer, komputer saraf, dan Komputer kuantum. Kebanyakan komputer Universal, dan dapat menghitung fungsi apapun multisektoral yang dapat dikomputasi, dan dibatasi hanya oleh mereka kapasitas memori dan kecepatan operasi. Namun desain yang berbeda komputer dapat memberikan kinerja yang sangat berbeda untuk masalah khusus; misalnya Komputer kuantum berpotensi dapat mematahkan beberapa algoritma enkripsi modern (oleh anjak kuantum) sangat cepat.

 

Ketika komputer pertama kali muncul, mereka mengambil keseluruhan kamar dan diperlukan pelatihan khusus untuk mengoperasikannya. Kemudian mereka tiba di rumah kita dan cukup sederhana bagi remaja untuk menjadi terampil dalam penggunaannya dalam beberapa hari (meskipun orang dewasa cenderung sedikit lebih lambat). Hari ini, putriku tiga tahun bermain dengan iPad nya secara alami sebagai dia bermain dengan bonekanya.

Sekarang, komputer sendiri menghilang. Mereka sedang tertanam tak terlihat ke Web hal, ke dalam no-sentuhan antarmuka dan kehidupan sehari-hari. Sementara kita telah lama tertinggal pemuatan disk ke dalam slot untuk mendapatkan komputer kita untuk bekerja dan menjadi digunakan untuk perangkat lunak sebagai layanan-hardware sebagai layanan tepat di sudut jalan.

Itulah mengapa perusahaan teknologi menjadi semakin konsumen didorong, berinvestasi dalam hal-hal seperti konten asli untuk mendapatkan kita onboard platform mereka, dari mana kita akan masuk ke layanan online secara besar-besaran untuk menghibur dan mendidik diri kita sendiri.

Masa depan teknologi ini, ironisnya, semua terlalu manusia.

 

Hari ini, kita berada di ambang paradigma digital baru, yang mana kemampuan teknologi kami mulai melampaui kita sendiri. Komputer memutuskan mana produk untuk saham di rak-rak, melakukan penemuan hukum dan bahkan memenangkan menunjukkan permainan. Mereka akan segera mengemudi mobil kami dan membuat diagnosis medis.

Nah begitulah bro, tentang komputer, bahwa komputer sudah mulai dan bisa berfikir dan bertindak layaknya manusia. Hingga tercipta robot yang menggantikan fungsi dan kerja manusia.

Semoga selanjutnya komputer lebih bermanfaat untuk mempermudah kehidupan manusia.
