Kablosuz Ağları Korumanın Farklı Yolları Nelerdir?

WEBVTT 00:00:02.574 --> 00:00:05.255 Was sind also die verschiedenen Möglichkeiten, um drahtlose Netzwerke zu schützen? 00:00:11.096 --> 00:00:15.777 Es wurden verschiedene Zugangssicherheitsmethoden entwickelt, um den Datenverkehr in einem drahtlosen Netzwerk zu schützen. 00:00:16.758 --> 00:00:23.099 Durch diese Methoden können wir den Netzwerkzugriff einschränken, verwalten und Daten in verschlüsselter Form übertragen. 00:00:26.260 --> 00:00:30.241 Lassen Sie uns unser Wissen über die Methoden zum Schutz drahtloser Netzwerke erweitern. 00:00:33.476 --> 00:00:37.780 Die Möglichkeiten zum Schutz drahtloser Netzwerke können in 5 Hauptbereichen betrachtet werden. 00:00:38.280 --> 00:01:00.598 Einer davon ist die Web Wired Equivalent Privacy VPA Wi-Fi Protected Access VPA2 Wi-Fi Protected Access 2 4 MAC Media Access Control Filter 5 SSID Service Set Identifier 00:01:00.618 --> 00:01:07.947 VPA und VPA2, MAC und SSID sind englische Begriffe. 00:01:09.068 --> 00:01:14.211 Die hier angegebenen türkischen Entsprechungen sind türkische Begriffe, die wir direkt verwenden können. 00:01:15.452 --> 00:01:21.896 Wi-Fi ist eine häufig verwendete englische Abkürzung für Wireless Local Area Network. 00:01:22.277 --> 00:01:23.998 Lassen Sie uns hier bitte keine Verwirrung stiften. 00:01:29.625 --> 00:01:32.670 Lassen Sie uns jetzt WEB, also Wired Equivalent Privacy, verstehen. 00:01:33.031 --> 00:01:35.074 Verstehen wir die kabeläquivalente Privatsphäre. 00:01:36.834 --> 00:01:42.419 Web ist die älteste Verschlüsselungsmethode, die in drahtlosen Netzwerkverbindungen auf der Datenebene arbeitet. 00:01:42.519 --> 00:01:48.023 Es ist also eine Maßnahme zur Sicherung der primitivsten Datensicherheit und Netzwerksicherheit. 00:01:48.964 --> 00:01:50.965 Das Web ist heutzutage eine veraltete Technologie. 00:01:51.526 --> 00:01:59.672 Das Ziel des Webs ist es, die gleiche Datensicherheit bereitzustellen, die wir mit Kabelverbindungen haben, wenn wir drahtlos verbunden sind. 00:02:01.772 --> 00:02:06.994 Die Standard-Webverschlüsselung wird als Web64 bezeichnet und verwendet einen 40-Bit-Schlüssel. 00:02:08.155 --> 00:02:12.776 Obwohl diese Information in unserem Kontext nicht wichtig ist, ist sie technisch gesehen bedeutend. 00:02:13.537 --> 00:02:18.859 In den heutigen Netzwerken, die das Web nutzen, trifft man häufig auf das Web128-System, das einen 104-Bit-Schlüssel verwendet. 00:02:19.459 --> 00:02:25.982 Sicherere Netzwerke können das Web256-System verwenden, das einen 232-Bit-Schlüssel ermöglicht. 00:02:26.782 --> 00:02:34.084 Wir dürfen nicht vergessen, dass das Web heutzutage eine veraltete Technologie ist und nicht weit verbreitet genutzt wird. 00:02:41.267 --> 00:02:44.208 WPA, Wi-Fi Protected Access. 00:02:44.868 --> 00:02:46.649 Sicherer Zugriff auf drahtlose Netzwerke. 00:02:48.269 --> 00:02:51.530 Der Standard für geschützten Wi-Fi-Zugriff und seine Erweiterung, WPA2. 00:02:52.111 --> 00:02:55.472 Wie bereits erwähnt, werden wir dies nun etwas genauer betrachten. 00:02:55.532 --> 00:02:58.213 Es repräsentiert eine wichtige technologische Entwicklung in drahtlosen Netzwerken. 00:02:59.505 --> 00:03:02.887 VLAN-Geräte werden derzeit nach diesem Standard zertifiziert. 00:03:04.548 --> 00:03:07.649 Wenn wir uns das Bild ansehen, sehen wir ein Modem in der Mitte. 00:03:08.149 --> 00:03:08.810 Also einen Server. 00:03:11.891 --> 00:03:13.092 Server-Router. 00:03:14.093 --> 00:03:26.819 Dieser Server und der Router, der als Modem fungiert, ermöglichen die Kommunikation zwischen der Welt, einem beliebigen Server, unserem Gerät, sozialen Netzwerken und unserem Computer, wie wir alle aus früheren Abschnitten wissen. 00:03:26.879 --> 00:03:28.419 VPA schützt unsere drahtlose Verbindung zu all diesen Netzwerken im Wesentlichen an unserem ersten Verbindungspunkt. 00:03:30.000 --> 00:03:39.164 VPA2, Wi-Fi Protected Access 2, ist eine Erweiterung von VPA, also können wir es als ein neues Modell betrachten. 00:03:54.389 --> 00:03:56.330 VPA2, VPA's. 00:03:59.022 --> 00:04:04.226 Heutzutage ist es die am häufigsten verwendete Verbindungssicherheitsmethode in persönlichen und gemeinsam genutzten Bereichen. 00:04:04.906 --> 00:04:08.188 VLAN-Geräte werden derzeit nach diesem Standard zertifiziert. 00:04:08.949 --> 00:04:16.574 Das bedeutet, dass alle von uns verwendeten drahtlosen Zugangssysteme heute nach dem VPA2-Sicherheitsprotokoll konfiguriert sind. 00:04:25.120 --> 00:04:31.264 Außer VPA werden auch einige verschiedene A-Schutzmethoden auf unterschiedliche Weise behandelt. 00:04:32.184 --> 00:04:32.845 Wir haben über MAC gesprochen. 00:04:33.085 --> 00:04:34.786 Media Access Control-Filter. 00:04:34.966 --> 00:04:37.166 Media Access Control-Filter auf Türkisch. 00:04:38.267 --> 00:04:46.013 Die MAC-Adresse jedes A-Adapters für kabelgebundene Ethernet- oder drahtlose Verbindungen wird als einzigartige Media Access Control bezeichnet. 00:04:46.133 --> 00:04:47.854 hat eine einzigartige Kennung. 00:04:49.212 --> 00:04:53.456 Die MAC-Adresse informiert den VLAN-Router darüber, welches Gerät gerade verbunden ist. 00:04:53.815 --> 00:04:55.498 Es führt also eine Filterung durch. 00:04:56.178 --> 00:05:04.747 Als zusätzliche Sicherheitsmaßnahme können zukünftig die MAC-Adressen der Geräte, die auf das drahtlose Netzwerk bzw. VLAN zugreifen werden, in den Router eingegeben werden. 00:05:05.307 --> 00:05:06.988 Es kann also eine Identifizierung vorgenommen werden. 00:05:08.270 --> 00:05:12.214 Eine Identifizierung der Benutzer und Arbeitsstationen kann vorgenommen werden. 00:05:13.632 --> 00:05:15.553 Es ist auch möglich, dass MAC-Adressen falsch sind. 00:05:15.853 --> 00:05:21.555 Deshalb ist dieser Filter nur eine zusätzliche Maßnahme und wird niemals eine sichere Verschlüsselung ersetzen. 00:05:22.755 --> 00:05:31.178 Kamlulu Ethernet ermöglicht den Austausch von Datenpaketen zwischen Geräten im lokalen Netzwerk. 00:05:32.697 --> 00:05:40.382 Denken Sie daran, dass die Verwendung von kabelgebundenem Ethernet die wichtigste Maßnahme ist, die wir für die Sicherheit unserer A- und Daten haben können. 00:05:40.982 --> 00:05:43.684 Es ist jedoch nicht immer möglich, immer kabelgebundenes Internet zu verwenden. 00:05:43.884 --> 00:05:53.270 Deshalb wird die Verwendung von MAC-Adressenfilterung neben VPi2 und VPi2 unsere Sicherheit erhöhen, wie wir bereits erwähnt haben. 00:05:58.251 --> 00:06:03.294 SSID Service Set Identifier, auf Deutsch Service-Set-Kennung. 00:06:03.875 --> 00:06:07.437 Die Abkürzung SSID steht für Service Set Identifier. 00:06:08.257 --> 00:06:13.940 Die Zeichenfolge des SSID, auch als Netzwerkname bezeichnet, kann maximal 32 Zeichen lang sein. 00:06:15.282 --> 00:06:26.837 Diese Zeichenfolge wird für die Konfiguration eines VLANs, also eines lokalen Netzwerks, des drahtlosen lokalen Netzwerks, des Access Points (AP) konfiguriert und von allen Clients, die Zugriff darauf haben, 00:06:26.976 --> 00:06:30.600 von diesem Zugriffspunkt aus eingestellt. 00:06:31.620 --> 00:06:36.244 Ein Zugriffspunkt ist ein elektronisches Gerät, das als Schnittstelle für drahtlose Kommunikationsgeräte dient. 00:06:37.525 --> 00:06:42.988 Es handelt sich also um das, was wir als Modem bezeichnen oder einen Wi-Fi Access Point. 00:06:43.509 --> 00:06:47.572 Lassen Sie uns diese Informationen unter Berücksichtigung der vorherigen Abschnitte im Gedächtnis behalten. 00:06:48.755 --> 00:06:52.036 Die Zeichenfolge wird unverschlüsselt allen Paketen hinzugefügt. 00:06:52.315 --> 00:06:55.177 Daher kann es nützlich sein, die Standardeinstellung zu ändern. 00:06:55.737 --> 00:07:01.799 Die SSID-Einstellungen befinden sich unter den meisten drahtlosen LAN-Routern im Modem. 00:07:04.339 --> 00:07:14.486 Lassen Sie uns nun, wenn Sie möchten, ein beliebiges Modem in Ihrem Zuhause oder in Ihrer Nähe entfernen und die Abschnitte wie VPA2, 00:07:14.706 --> 00:07:16.267 SSID darunter betrachten. 00:07:16.787 --> 00:07:20.630 Auf diese Weise können wir die Informationen, die wir gelernt haben, viel klarer beobachten. 00:07:21.330 --> 00:07:27.474 Lassen Sie uns beispielsweise sehen, ob die SSID tatsächlich 32 Zeichen lang ist und aus welchen Arten von Zeichen sie besteht.

WEBVTT 00:00:02.574 --> 00:00:05.255 So what are the different ways to protect wireless networks? 00:00:11.096 --> 00:00:15.777 Various access security methods have been developed to protect data traffic on a wireless network. 00:00:16.758 --> 00:00:23.099 Through these methods, we can restrict network access, manage it, and transmit data in encrypted form. 00:00:26.260 --> 00:00:30.241 Let's expand our knowledge about wireless network protection methods. 00:00:33.476 --> 00:00:37.780 The ways to protect wireless networks can be discussed in 5 main areas. 00:00:38.280 --> 00:01:00.598 One of these is Web Wired Equivalent Privacy WPA Wi-Fi Protected Access WPA2 Wi-Fi Protected Access 2 4 MAC Media Access Control Filter 5 SSID Service Set Identifier 00:01:00.618 --> 00:01:07.947 VPA and VPA2, MAC, and SSID are terms in English. 00:01:09.068 --> 00:01:14.211 The Turkish equivalents we provide here are Turkish terms that can be used directly. 00:01:15.452 --> 00:01:21.896 Let's not forget that Wi-Fi is a widely used English abbreviation for wireless local area network. 00:01:22.277 --> 00:01:23.998 Let's not get confused here. 00:01:29.625 --> 00:01:32.670 Now let's understand WEB, which stands for Wired Equivalent Privacy. 00:01:33.031 --> 00:01:35.074 Let's understand wired equivalent privacy. 00:01:36.834 --> 00:01:42.419 WEB is the oldest encryption method that operates at the data link layer in wireless network connections. 00:01:42.519 --> 00:01:48.023 So, it is a precaution taken to protect the most primitive data security and network security. 00:01:48.964 --> 00:01:50.965 The web is now an outdated technology. 00:01:51.526 --> 00:01:59.672 The purpose of the web is to ensure that when we provide a wireless connection, it is used in the same secure way as data security over cables. 00:02:01.772 --> 00:02:06.994 The standard web encryption is known as web64 and uses a 40-bit key. 00:02:08.155 --> 00:02:12.776 Although this information may not be important in our current context, it is technically significant. 00:02:13.537 --> 00:02:18.859 Today, networks using the web mostly encounter the web128 system, which uses a 104-bit key. 00:02:19.459 --> 00:02:25.982 More secure networks may be using the web256 system, which allows for a 232-bit key. 00:02:26.782 --> 00:02:34.084 We must not forget that the web is now an outdated technology and is not widely used. 00:02:41.267 --> 00:02:44.208 WPA, Wi-Fi Protected Access. 00:02:44.868 --> 00:02:46.649 Secure access to wireless networks. 00:02:48.269 --> 00:02:51.530 Wi-Fi Protected Access standard and its extension, WPA2. 00:02:52.111 --> 00:02:55.472 As mentioned earlier, we will now delve into more detail. 00:02:55.532 --> 00:02:58.213 Represents a significant technological advancement in wireless networks. 00:02:59.505 --> 00:03:02.887 VLAN devices are currently being certified according to this standard. 00:03:04.548 --> 00:03:07.649 Looking at the diagram, we see a modem in the middle. 00:03:08.149 --> 00:03:08.810 In other words, a server. 00:03:11.891 --> 00:03:13.092 Server router. 00:03:14.093 --> 00:03:26.819 We all know from previous sections that this server and modem acting as a router provide communication between the world, any server, our devices, social networks, and our computers. 00:03:26.879 --> 00:03:28.419 VPA ensures that our wireless connection to all these networks is essentially protected at our first connection point. 00:03:30.000 --> 00:03:39.164 VPA2, Wi-Fi Protected Access 2, is an extension of VPA, which is the most common connection security method in personal and shared usage areas today. 00:03:46.186 --> 00:03:53.849 VPA2, Wi-Fi Protected Access 2, is an extension of VPA, which is the most common connection security method in personal and shared usage areas today. 00:03:54.389 --> 00:03:56.330 So we can think of VPA2 as a new model. 00:03:56.670 --> 00:03:57.891 VPA2, VPA's. 00:03:59.022 --> 00:04:04.226 Today, all wireless access systems we use are organized according to the VPA2 security protocol. 00:04:04.906 --> 00:04:08.188 VLAN devices are currently being certified according to this standard. 00:04:08.949 --> 00:04:16.574 So all wireless access systems we use are organized according to the VPA2 security protocol. 00:04:25.120 --> 00:04:31.264 Apart from VPA, let's also consider some different ways in a few other A-Protection methods. 00:04:32.184 --> 00:04:32.845 We mentioned MAC. 00:04:33.085 --> 00:04:34.786 Media Access Control Filter. 00:04:34.966 --> 00:04:37.166 Media Access Control Filter in Turkish. 00:04:38.267 --> 00:04:46.013 For wired Ethernet or wireless connections, the MAC address of each A adapter is unique, called media access control. 00:04:46.133 --> 00:04:47.854 it has a unique identifier. 00:04:49.212 --> 00:04:53.456 The MAC address informs the VLAN router which device is currently connected. 00:04:53.815 --> 00:04:55.498 In other words, it performs filtering. 00:04:56.178 --> 00:05:04.747 As a further security measure, the MAC addresses of devices that will access the wireless area or VLAN in the future can be entered into the router. 00:05:05.307 --> 00:05:06.988 So, an identification can be made. 00:05:08.270 --> 00:05:12.214 An identification can be made for users and workstations. 00:05:13.632 --> 00:05:15.553 MAC addresses can also be incorrect. 00:05:15.853 --> 00:05:21.555 Therefore, this filter is only an additional measure and will never be enough to replace secure encryption. 00:05:22.755 --> 00:05:31.178 Camellia Ethernet allows data packets between devices connected to the local area network to be exchanged. 00:05:32.697 --> 00:05:40.382 Let's not forget that using wired Ethernet is the most important measure we can take for our A security and data security. 00:05:40.982 --> 00:05:43.684 However, it is not always possible for us to use wired internet. 00:05:43.884 --> 00:05:53.270 Therefore, as we mentioned earlier, using MAC, i.e. media access control, filters in addition to VPNs will enhance our security. 00:05:58.251 --> 00:06:03.294 SSID stands for Service Set Identifier. 00:06:03.875 --> 00:06:07.437 The abbreviation SSID stands for Service Set Identifier. 00:06:08.257 --> 00:06:13.940 The character string, also known as the SSID, can be up to 32 characters long. 00:06:15.282 --> 00:06:26.837 This character string is configured as the Access Point (AP) for a VLAN, i.e., a local network, wireless local area network, and is accessible by all clients connected to this access point. 00:06:26.976 --> 00:06:30.600 All clients connected to this access point make a setting for this access point. 00:06:31.620 --> 00:06:36.244 An access point is an electronic device that serves as an interface for wireless communication devices. 00:06:37.525 --> 00:06:42.988 In other words, it is what we refer to as a modem or a Wi-Fi Access Point. 00:06:43.509 --> 00:06:47.572 Let's keep this information in mind considering the previous sections. 00:06:48.755 --> 00:06:52.036 The character string is added to all packets unencrypted. 00:06:52.315 --> 00:06:55.177 Therefore, it would be beneficial for us to change the default setting. 00:06:55.737 --> 00:07:01.799 SSID settings are found under most wireless local area routers. 00:07:04.339 --> 00:07:14.486 Let's now remove the device, which is the modem or access point in your home or nearby, and look at the sections underneath, such as VPA2 and SSID. 00:07:14.706 --> 00:07:16.267 This way, we can observe the information we have learned much more clearly. 00:07:16.787 --> 00:07:20.630 For example, let's see if the SSID, which is 32 characters long, is really made up of 32 characters and what kind of characters they are.

WEBVTT 00:00:02.574 --> 00:00:05.255 Peki kablosuz ağları korumanın farklı yolları nelerdir? 00:00:11.096 --> 00:00:15.777 Kablosuz bir ağdaki veri trafiğini korumak için farklı erişim güvenliği yöntemleri geliştirilmiştir. 00:00:16.758 --> 00:00:23.099 Bu yöntemler sayesinde ağ erişimi kısıtlayabiliriz, yönetebiliriz ve verileri şifelenmiş biçimde iletebiliriz. 00:00:26.260 --> 00:00:30.241 Kablosuz ağları koruma yöntemleriyle ilgili gelin bilgimizi biraz daha genişletelim. 00:00:33.476 --> 00:00:37.780 Kablosuz ağları korumanın yolları 5 tane ana alanda ele alınabilir. 00:00:38.280 --> 00:01:00.598 Bunlardan birincisi Web Kabloya eşdeğer gizlilik VPA Wi-Fi Korumalı Erişim VPA2 Wi-Fi Korumalı Erişim 2 4 MAC Medya Erişim Kontrolü Filtresi 5 SSID Hizmet 00:01:00.618 --> 00:01:07.947 Kümesi Tanımlayıcısı VPA ve VPA2, MAC ve SSID İngilizce olan terimlerdir. 00:01:09.068 --> 00:01:14.211 Burada verdiğimiz Türkçe karşılıkları birebir olarak kullanabileceğimiz Türkçe terimlerdir. 00:01:15.452 --> 00:01:21.896 Wi-Fi unutmayalım ki kablosuz yerel ağın yaygın olarak kullanılan bir İngilizce kısaltmasıdır. 00:01:22.277 --> 00:01:23.998 Burada lütfen bir karışıklık yaşamayalım. 00:01:29.625 --> 00:01:32.670 Şimdi gelin WEB yani Wired Equal and Privacy. 00:01:33.031 --> 00:01:35.074 Kabloya eşdeğer gizliliği anlayalım. 00:01:36.834 --> 00:01:42.419 Web, kablosuz ağ bağlantılarında veri bağı tabakası çalışan en eski şifreleme yöntemidir. 00:01:42.519 --> 00:01:48.023 Yani en ilkel veri güvenliğini korumaya dair, ağ güvenliğini korumaya dair alınmış önlemdir. 00:01:48.964 --> 00:01:50.965 Web günümüzde eskimiş bir teknolojidir. 00:01:51.526 --> 00:01:59.672 Web'in amacı, kablo olarak nasıl bir veri güvenliğine sahipsak kablosuz olarak bir bağlantı sağladığımızda da bunun aynı şekilde kullanılmasını sağlamaktır. 00:02:01.772 --> 00:02:06.994 Standart olan web şifrelemesi web64 olarak bilinir ve 40 bitlik bir anahtar kullanılır. 00:02:08.155 --> 00:02:12.776 Bu bilgi her ne kadar bizim konjuktürümüz içerisinde önemli olmasa da teknik olarak önemli bir bilgidir. 00:02:13.537 --> 00:02:18.859 Günümüzde web kullanan ağlarda daha çok 104 bitlik anahtar kullanan web128 sistemine rastlanır. 00:02:19.459 --> 00:02:25.982 Daha güvenli ağlar ise 232 bitlik anahtarı mümkün kılan web256 sistemini kullanıyor olabilir. 00:02:26.782 --> 00:02:34.084 Unutmamamız gereken şey Web'in günümüzde eskimiş bir teknoloji oldu ve yaygınlıkla kullanılmadığıdır. 00:02:41.267 --> 00:02:44.208 WPA, Wi-Fi Protected Access. 00:02:44.868 --> 00:02:46.649 Kablosuz ağa güvenli erişim. 00:02:48.269 --> 00:02:51.530 Wi-Fi korumalı erişim standartı ve onun uzantısı WPA2. 00:02:52.111 --> 00:02:55.472 Az önce bahsetmiştik, şimdi biraz daha detaylı ele alacağız. 00:02:55.532 --> 00:02:58.213 Kablosuz ağlarda önemli bir teknolojik gelişmeyi temsil eder. 00:02:59.505 --> 00:03:02.887 VLAN cihazları şu anda bu standarda göre sertifikalandırılmaktadır. 00:03:04.548 --> 00:03:07.649 Şekle baktığımızda ortada bir adet modem görüyoruz. 00:03:08.149 --> 00:03:08.810 Yani sunucu. 00:03:11.891 --> 00:03:13.092 Sunucu yönlendirici. 00:03:14.093 --> 00:03:26.819 Bu sunucu ve yönlendirici görevi gören modem, dünya, herhangi bir server, cihazımız, sosyal ağlar ve bilgisayarımız arasındaki iletişimi sağladığını hepimiz 00:03:26.879 --> 00:03:28.419 daha önceki bölümlerden biliyoruz. 00:03:30.000 --> 00:03:39.164 VPA bizim kablosuz olarak tüm bu ağlara bağlantımızı temel olarak ilk bağlantı noktamızda koruma altına alınmamızı sağlar. 00:03:46.186 --> 00:03:53.849 VPA2, Wi-Fi Protected Access 2 yani kablosuz ağ güvenli erişim 2 ise, VPA'nın bir uzantısıdır. 00:03:54.389 --> 00:03:56.330 Yani yeni bir model olarak düşünebiliriz. 00:03:56.670 --> 00:03:57.891 VPA2, VPA'nın. 00:03:59.022 --> 00:04:04.226 Günümüzde kişisel ve ortak kullanım alanlarında en sık rastlanılan bağlantı güvenlik yöntemidir. 00:04:04.906 --> 00:04:08.188 VLAN cihazları şu anda bu standarda göre sertif kalandırılmaktadır. 00:04:08.949 --> 00:04:16.574 Yani bizim kullandığımız tüm kablosuz erişim sistemleri günümüzde VPA2 güvenlik protokolüne göre düzenlenmektedir. 00:04:25.120 --> 00:04:31.264 VPA dışında gelin birkaç farklı A-Koruma yönteminde bazı farklı yolları da ele alın. 00:04:32.184 --> 00:04:32.845 MAC demiştik. 00:04:33.085 --> 00:04:34.786 Media Access Control Filtresi. 00:04:34.966 --> 00:04:37.166 Media Giriş Kontrolü Filtresi Türkçe olarak. 00:04:38.267 --> 00:04:46.013 Kablolu Ethernet veya kablosuz bağlantılar için her A bağdaştırıcısının MAC adresi, media erişim denetimi adı verilen özgün, 00:04:46.133 --> 00:04:47.854 benzeri olmayan bir tanımlayıncısı vardır. 00:04:49.212 --> 00:04:53.456 MAC adresi VLAN yönlendiriciye o anda hangi cihazın bağlı olduğunu bildirir. 00:04:53.815 --> 00:04:55.498 Yani bir filtreleme gerçekleştirir. 00:04:56.178 --> 00:05:04.747 Daha ileri bir güvenlik önlemi olarak gelecekte kablosuz yere la yani VLAN'a erişecek olan cihazın MAC adresleri yönlendiriciye girilebilir. 00:05:05.307 --> 00:05:06.988 Yani bir tanımlama yapılabilir. 00:05:08.270 --> 00:05:12.214 Kullanıcı ve iş istasyonlarına dair bir tanımlama yapılabilir. 00:05:13.632 --> 00:05:15.553 MAC adreslerin yanlış olması da mümkündür. 00:05:15.853 --> 00:05:21.555 Bu nedenle bu filtre yalnızca ek bir önlemdir ve güvenli bir şifrelemenin yerini almaya asla yetmeyecektir. 00:05:22.755 --> 00:05:31.178 Kamlulu Ethernet verilerin yerel alan ağına bağlı cihazlar arasındaki veri paketleri şeklinde değiştirilmesini sağlar. 00:05:32.697 --> 00:05:40.382 Unutmayalım ki kablolu ethernet kullanmak bizim A güvenliğine ve veri güvenliğimize karşı alabileceğimiz en önemli önlemdir. 00:05:40.982 --> 00:05:43.684 Fakat her zaman kablolu internet kullanmamız mümkün değildir. 00:05:43.884 --> 00:05:53.270 Bu sebeple az önce de bahsettiğimiz gibi VPi2 ve VPi2'ye ek olarak MAC yani medya giriş kontrolü filtresini kullanmamız güvenliğimizi arttıracaktır. 00:05:58.251 --> 00:06:03.294 SSID Service Set Identifier, hizmet kümesi tanımlayıcısı Türkçe olarak. 00:06:03.875 --> 00:06:07.437 SSID kısaltması hizmet kümesi tanımlayıcısı anlamına gelir. 00:06:08.257 --> 00:06:13.940 Ağ adı olarak da adlandırılan SSID karakter dizgisi en fazla 32 karakter uzunluğunda olabilir. 00:06:15.282 --> 00:06:26.837 Bu karakter dizgisi bir VLAN'ın, yani yerel ağın, kablosuz yerel alan ağın, AP yani Access Point erişim noktası olarak yapılandırılır ve buna erişim olan, 00:06:26.976 --> 00:06:30.600 bu erişim noktasına olan tüm istemciler tarafından bir ayar yapılır. 00:06:31.620 --> 00:06:36.244 Erişim noktası kablosuz iletişim cihazları için ara birim görevi gören elektronik bir cihazdır. 00:06:37.525 --> 00:06:42.988 Yani modemden bahsettiğimiz şey veya bir Wi-Fi Access Point erişim noktasıdır. 00:06:43.509 --> 00:06:47.572 Bu bilgiyi az önceki bölümlere göz önüne bulundurarak aklımıza tutalım. 00:06:48.755 --> 00:06:52.036 Karakter dizgisi şifelenmemiş biçimde tüm paketlere eklenir. 00:06:52.315 --> 00:06:55.177 Bu nedenle varsayılan ayarı değiştirmemiz faydalı olacaktır. 00:06:55.737 --> 00:07:01.799 SSID ayarları çoğu kablosuz yerel alan yönlendiricisinin modemi altında bulunur. 00:07:04.339 --> 00:07:14.486 Gelin isterseniz şimdi evinizdeki veya yakınımızdaki herhangi bir modemi yani erişim noktasını Kaldıralım cihazı ve altındaki VPA2, 00:07:14.706 --> 00:07:16.267 SSID gibi bölümlere bakalım. 00:07:16.787 --> 00:07:20.630 Bu şekilde öğrendiğimiz bilgileri çok daha net bir şekilde gözlemlememiz. 00:07:21.330 --> 00:07:27.474 Mesela 32 karakter uzunluğunda olan SSID'nin gerçekten 32 karakterden ve ne tür karakterlerden oluştuğunu görelim.
