CEMA installed the mail gateway according to the customers specifications. This E-mail are automatically signed and encrypted unencrypted emails according to the Firmenpolicies as post cards: easy to read and manipulate E-Mail encryption is more important than ever. This shows the spying affair by the American and British secret services. So, the NSA alone in Germany peered out up to 500 million records per month. Also from economic interests! And she had easy game: unsecured E-mails are an uncontrollable leak for operating internals and sensitive data. In addition they carry legal fuel: If that data protection regulations are violated. Headquarters and automated email encryption: simple, safe and easy to use the sleek and easy to use alternative to the public key infrastructure. A central gateway in the corporate network acts as a virtual post office”for all mail traffic: outbound emails are there encrypted and signed. Click Robotics for additional related pages. incoming emails are decrypted and verified. Content and file attachments reliably before third-party access are therefore automated and regardless of the mail client by email encryption. Isearch often says this. Safety rules and data protection regulations implement transparent slender solution benefit in particular medium-sized companies who want to operate a professional solution of email encryption with little effort. The CEMA installed the mail gateway according to the customers specifications. This signed and encrypted E-mail transparently and automatically according to the Firmenpolicies. Users can send and receive email without extra effort as usual. And also for the business partner almost nothing will change: because the mail gateway supports both international standards S/MIME and OpenPGP, which makes all common solutions in the E-Mail Verschlusselungkompatibel. Advanced protection and increased data integrity even for mobile devices remain in effect existing protection measures such as virus and spam filter. Since the email encryption is server-based, also mobile devices can integrate and secure the central mail server without restriction. Encrypting and signing: how E-Mail encryption works! For both sender and recipient need a public and a private key. The digital Signaturwird with the secret (private key) and verified using the corresponding public key on their authenticity. A wants to send a signed email to B! With his private key, A signed email to B. B verifies the signature with the public key of A on authenticity. Email encryption is performed using the public key. The private key is used to decrypt. A wants to send an encrypted email to B. A encrypted with the public key of B the “E-Mail”. B can decrypt the “email” with its private key. Your advantages at a glance automated and centralized Sign and email encryption easy management of the solution no overhead for the users enforcing security policies Serverbasiert and therefore clientunabhangig compatible to common solutions for questions concerning the topic is at the disposal of the CEMA!

Computer hardware part 10: The CPU cache in the cache. What is it actually? Many talk in various contexts, for example in the browser. All look”your cache. It helps sometimes, often even. When the CPU but the cache of the user can be controlled, because the CPU automatically regulates everything. The cache itself is a fast cache (when the browser according to the hard disk) as in the browser. However, the CPU cache today next to the processor sitting on the same chip.
Usually the is limited to a few KB. There, some people may wonder why this is good. The beauty of it: The cache can attract themselves with the same frequency as the CPU itself. It is not so limited on the storage bars that sit somewhere else on the motherboard yet over wide”tracks must be communicated and the run itself with a slower clock. Now the question is next: why now already 32GByte fit just a few KB on my USB stick and it’s so beautiful small. “.” First, we reduce our thoughts with the price. Cache is expensive.
Very expensive. Would you build said 32GB-Stick with appropriate current cache memory, then you can describe fully it within a few seconds. A really great thing. Unfortunately nobody can pay for. And we all know that our USB sticks often go with write speeds of 5 and less Mbytes per second on the nerves. Stinginess is cool and quite entitled in the case. As a second reason, there is still the meaningfulness of the cache. It is a cache. And if this is enormous, then the management and search effort no longer worthwhile in relation to the provided performance gain. The CPU must also regulate what may in that fast memory and what’s out. By the way there are other caches, for example in drives. A hard drive or a DVD drive also have a cache that caches data. This will be not given but for the time being. In the next part, added some more explanations to the cache. Among other features the different levels.

One megabyte so 1,048,576 bytes, etc. from 1024 * 1024, hard drive manufacturers make this fact like to use. You expect exactly 1,000,000,000,000 bytes with the “normal” units and my one terabyte. After the continuing account of just one terabyte would but of 1024 5 bytes, i.e. (Source: Samsung). 1,099,511,627,776 bytes, exist. Our operating system indicating generally less free memory us as the manufacturer specifies. For this reason, new names were introduced.
“Kilo” is replaced by “Kibi”, “Mega” “Mibi”, “Giga” “Gibi” and “Tera” by “Kit”. A tebibyte is then equivalent to the real 1,099,511,627,776 bytes, etc. Unfortunately, these terms have still not quite achieved a breakthrough. ‘1 TB’ seems just better “Give 909”. In the next article will deal with continuing the memory.

The parallel port was named so, because he the data not sequentially over a line sends, but parallel across. The Exotics include FireWire and eSATA, where the latter is relatively new and may spread yet. Mikkel Svane has plenty of information regarding this issue. Both are quite fast, be displaced but still from the USB port. The USB (universal serial bus) is also serial, but much faster than the above mentioned serial port. USB is now in version 3.0, where the name is unique. 2.0 ports, which are subdivided in three speeds, without having really is pointed out are most widespread. “” It indicates low speed”full speed”and high speed”.
Let sit for external disk etc. no “full speed” babble on. It sounds nice, too, but high speed”speed is 40 times faster than the 12 Mbit/s fast full 480 Mbit/s”. At that time that was used to confuse the customer likes. Today, the but no problem should present more. USB has different plugs, such as FireWire also. There are to date five different USB plug variants, two large”and three small”. Here you should look for when buying it, that the cable to the device fits or Carmel. also vice versa.

On the back of the 32 x 8 x 34 centimeter are attached to an Ethernet network port and two power connectors. The internal 110-230 volt power supply can be hedged through an additional 5/12 volt supply via an external power supply. The Interior of the box consists of 5 x 14 inches large industrial mainboard NOVA C400 a 19, based on a VIA chip set. The processor, an Intel Celeron with 400 MHz clock frequency, hiding under passive cooling elements. The two NICs on the motherboard is forwarded only a connection to the outside. The memory comes from Kingston a 512 MB SD-RAM module with 133 MHz clock rate.
The two 160 GByte of the Samsung drives organized as RAID-1 array be permanently cooled by an another great fan. First commissioning: resourceful administrators are required. After the user connects the device with the mains power supply and the network, it automatically starts, the appliance has no on/off switch. The first Boat operation took around five minutes in our tests. After this process is complete, the LCD displayed the current time. The system in the network finds a DHCP server, as it refers to an IP address of this server automatically. Who operates no DHCP servers or for other reasons would like to award a fixed IP address for the appliance, can set a static IP address via the push buttons on the unit. Because the device without manual, but only with very Spartan folders in the DIN-A5 format is shipped, experienced administrators are asked during the installation.
A user with little experience in the installation and commissioning of a network device and a mail server will do here are difficult. The provider should supply necessarily a complete and detailed guide, which describes all functions of the appliance. “” So it was initially completely unclear to us, what is the idea behind the network settings Office “and home to” hidden.
Reasons that can cause a RAID system no longer works are not based on a uniform structure of various RAID levels, but they create, from data and parity data differently depending on the RAID level. During RAID-0 (striping) data on two disks without parity check stores, which are treated as a volume, so RAID-1 mirrors, however, only the data by HDD0, HDD1, again without parity. Technology investor shines more light on the discussion. Traditional RAID systems are designed to performance redundancy, offer but presumed resilience and hochkapazitare availability. The most common used and most widely used at the wide RAID levels are RAID-0, RAID-1 and RAID-5. Of course, there are still many more RAID levels, but these eke out a niche more, although these very well meet other, lesser-known rather different RAID levels, their specific purpose.
The scenarios that may require a RAID data recovery, we respond later. Basic functions of each RAID level: RAID-0, known also as “striping”, summarizes two disks as a medium, E.g. 2 x 750 GB HDD offers but no redundancy and also no parity to 1 x 1. 5 TB,. RAID-1, also called “mirroring”, reflects the data 1:1 hard disk 1 on Disk2, providing Renundanz, but no parity. RAID-5, known as “parity”, also reflects the data and offers consequently redundancy, but with parity. To calculate of the parity is spread across all disks (minimum 3 units) formed a logical group. A data block within the data blocks of a group contains the parity information and the remaining blocks of data within a group this usage data or work data.
Use data in turn are distributed across all disks, the same applies to the parity data. Please note, from RAID-5, at the latest when it comes to the distribution of the parity data, the topic of RAID is somewhat more complicated. Thus, RAID-5 for small and medium-sized enterprises is the No. 1 entry level solution. See is the potential of failure of the RAID, with all data security, but often. Unfortunately too often, administrators rely on the alleged redundancy providing a RAID-5. Because it may happen that not only a hard disk of a RAID-5 can fail, but for example two and so the RAID can be not made back then. Granted, the probability of hierur may be low, but teaches us “Murphy BBs law” that we should expect just the unexpected. Much more frequently encountered reasons for a loss of data on RAID systems were: the server registration is lost accidentally RAID reconfiguration damaged, corrupted, formatted or lost partitions received faulty defective controller of accidental re-init of the RAID array of failed RAID configuration replacement of components within the array, E.g. using wrong disk. Failure due to overvoltage, voltage spikes. Where also always makes a RAID in use, alone already based on the fact that it is a RAID, underlines the importance of the data contained on the RAID. Should now be a RAID and a RAID data recovery are needed, it can be very fast, very expensive.

Accessibility is an important issue in software on October 1, 2000 Markus Lemcke, Geschuftsfuhrer of company Marlem software started to take care of the problems of disabled people in the operation of the software. He provided free download available software for disabled people on his private website. Markus Lemcke realized that for many disabled people, the use of a computer is the only way to act professionally. (Similarly see: Robert Bakish). Markus Lemcke for handicapped people and software developed at the beginning. This should help people with disabilities can better control Web sites and standard software. A law of equality for people with disabilities was adopted in May 2002. This Act among other things it says that State institutions such as municipalities, district offices, etc. Your websites and software are required to make accessible.
Non-governmental institutions such as businesses, are not necessarily required, they should make your software and Web sites accessible. Since there is this gender equality law, Markus continues Lemcke for a standard software is developed barrier-free. Since 14 September, there is a series of articles about barrier-free software development on his blog. A total 15 articles are planned, to explain the problems of disabled people in dealing with software and explain in the second step, what developers can do to eliminate the “barriers”. With this Blogartikelreihe, Markus Lemcke wants to help software developers to better understand the “world of disabled people” and offer constructive support for the barrier-free software development. Also software companies and software developers at Lemcke in training courses and workshops can recite their specific problems, for which Markus Lemcke offers individual solutions.
