FİREWALL ÇÖZÜMLERİ

 

İstenmeyen kişilerin ve uygulamaların bilgisayar sistemimize girmesini ve etkide bulunmasını istemeyiz. Bilgisayarlarımızda daha güvenli ve daha verimli bir çalışmanın dijital ortamda saklanabilmesi ve yerini koruyabilmesi için virüslerden ve saldırı ataklarından etkilenmemesi gerekir. Günümüz teknolojisinde hızla yayılan virüsleri, trojanları ve türevlerini düşünürsek ne kadar kalabalık ve ne kadar komplike bir sistematiğe sahip olduklarını görebiliriz. Bir günde en az 500'ün üzerinde virüslerin ve saldırıların olduğunu bilinmektedir. Peki bizler bu saldırılardan ve virüslerden nasıl korunacağız nasıl bilgilerimizi güvenle saklayacağız? İşte güvenlik bu en temel sorulardan başlayarak daha zor ve karmaşık soruların çözümünü bulmak ve bilgilerin sağlam ve güvenli bir ortamda korunmasını sağlamakla başlar ve değişik senaryolarla bilgi sistemimizi koruma altına alır.

Unutmayalım ki yıllarca klavyenin tuşlarına tek tek basarak oluşturduğumuz bilgilerimiz tek bir tuşla silinebilmektedir. Eğer tek bir tuşla yok olabiliyorsanız Güvende değilsinizdir.

Günümüzde her türlü otomasyonun en kritik sorunu bilgi güvenliği. Güvenliği bir zincire benzetebiliriz. Güvenliğin gücü en zayıf halkaya bağlıdır. Güvenliğin ilk halkası sisteme kendini tanıtma ve tanınma: kişisel şifreler, biyometrik tanınma ve giriş anahtarlarıdır.

İkinci halka ağ güvenliğidir. Yani işletim sistemi güvenliği, kullanıcı yetkileri, IP güvenliği ve DNS güvenliğidir.

Üçüncü halka web güvenliğidir. Yani merkezi ve dağıtılmış güvenlik duvarları, arındırılmış alanlar, açık anahtar altyapısı, dijital şifreleme, dijital sertifikalar ve dijital imza, sanal özel ağlar ve atak belirleme sistemleridir.

Bu arada kişisel bilgisayarlardaki bilgilerin güvenliğini de unutmamak gerekiyor. Kişisel güvenlik duvarları, disk üzerindeki verilerin şifrelenmesi vb. İşimiz en uygun parçaları seçip, sizin için gerekli güvenlik sürecini oluşturmaktır.

The Dell™ SonicWALL™ Gateway Anti-Virus, Anti-Spyware, Intrusion Prevention, and Application Intelligence and Control Service delivers intelligent, real-time network security protection against sophisticated attacks. Available on every Dell SonicWALL firewall, patented Reassembly-Free Deep Packet Inspection™ technology delivers protection from malware, intrusions and application exploits. Additionally, with the proliferation of Web 2.0 and social networking technologies for both work and personal use, Dell SonicWALL provides intelligence, control and visualization of network and application usage, with granular policies that can be created for both users and groups.

Gateway Anti-Virus and Anti-Spyware inspection.

Every day, Trojans, spyware, viruses and other malware threats become more sophisticated, and now have the ability to circle the entire globe in a matter of minutes. To complicate matters, many of these threats are blended, originating from multiple sources, operating at multiple layers, utilizing multiple protocols. Moreover, they are delivered via Instant Messaging (IM), peer-to-peer (P2P), file sharing, games or other seemingly benign applications that are not scanned by traditional client anti-virus solutions. Small wonder then, that today's complex threats require a solution that goes beyond the status quo.

The Dell SonicWALL Gateway Anti-Virus and Anti-Spyware

service inspects all email file attachments, ftp downloads, and real-time applications such as IM and P2P for total file-based threat control. Unlike other solutions, Dell SonicWALL RFDPI analyzes all files in real time—regardless of file size or compression—and generates proactive alerts that notify administrators whenever a threat is detected. Day-zero attacks are prevented with dynamically updated databases and an extensive list of virus and malware signatures. And, because all threats are blocked at the gateway, users are completely prevented from downloading malware in the first place. In addition, Dell SonicWALL prevents auto-installation of ActiveX components (one of the most common sources of spyware) and stops any existing spyware programs from communicating with their hosts.

Intrusion Prevention.

Application vulnerabilities, buffer overflows and blended threats can open up your network to exploits, making intrusion prevention a necessary technology. Dell SonicWALL goes a step beyond traditional solutions by scanning all network traffic for worms, Trojans, software vulnerabilities, backdoor exploits, and other types of malicious attacks. Utilizing a comprehensive signature database, the Dell SonicWALL Intrusion Prevention Service (IPS) engine protects against an array of network-based application vulnerabilities and exploits. Deployed to protect against both internal and external threats, Dell SonicWALL IPS monitors the network for malicious or anomalous traffic, then blocks or logs traffic based on predefined and automatically updated conditions. By focusing on known malicious traffic, Dell SonicWALL IPS decreases false positives while increasing network reliability and performance.  

Application Intelligence, Control and Visualization.

Dell SonicWALL Application Intelligence and Control provides granular control and real-time visualization of applications to guarantee bandwidth prioritization and ensure maximum network security and productivity. A tightly integrated feature of Dell SonicWALL Next-Generation Firewalls, it uses Dell SonicWALL Reassembly-Free Deep Packet Inspection™ to identify and control applications, regardless of port or protocol. With a continuously expanding signature database currently recognizing over 2,800 applications and millions of malware threats, it can maintain granular control over applications, prioritize or throttle bandwidth and deny Web site access. The Dell SonicWALL Application Flow Monitor provides real-time graphs of applications, ingress and egress bandwidth, active Website connections and user activity.

Dell™ SonicWALL™ Content Filtering Service (CFS) helps organizations and educational institutions enforce their productivity and protection policies and block inappropriate, illegal and dangerous Web content. Featuring a dynamic rating and caching architecture, Dell SonicWALL CFS blocks multiple categories of objectionable Web content and provides the ideal combination of control and flexibility to ensure the highest levels of productivity and protection. And as an added benefit, Dell SonicWALL content filtering is configured and controlled from the appliance, eliminating the need for a costly, dedicated filtering server.

An easy to manage solution.

Dell SonicWALL CFS combines application-based policy enforcement with comprehensive content filtering, in a cost-effective, easy-to-manage solution. URLs, IP addresses and domain ratings are locally on the firewall, reducing response time to frequently visited sites to a fraction of a second. Administrators can control bandwidth based upon Content Filtering Service rating, as well as specific IP addresses, sites—or even applications when combined with Dell SonicWALL Application Intelligence and Control.

Ideal for small to large organizations.

Dell SonicWALL CFS is deployed in a wide variety of organizations, including business enterprises, universities, libraries and government agencies, as well as distributed public Internet "hotspots." Ease of management, scalability and superior performance make CFS an ideal solution for larger enterprises with complex configuration requirements.

Mitigating risks of unrestricted access.

Dell SonicWALL CFS helps reduce the risks incurred by not restricting employees, students, or other users from accessing websites that are inappropriate or offensive, especially when there is a legal responsibility and obligation to keep the workplace free from offensive material. In addition, unrestricted access drains productivity by promoting wasteful Web surfing. Unrestricted access often leads to infection by viruses, spyware and malware, since many of the sites that are contained in blocked categories are common sources of malicious attacks. Installing a content filtering solution can eliminate these and other problems.

Flexibility and policy enforcement.

Administrators are free to create local or enterprise-wide policies that are specifically designed to meet their own requirements and legislative mandates. The dynamic rating architecture can be used to block up to 56 categories of objectionable or inappropriate Web content, providing a high level of transparent control, ease of administration and granular policy enforcement. The local URL filtering feature adds flexibility by letting administrators go beyond categories to block or allow specific domains or hosts. Policies can be applied to individuals or defined groups (e.g., students and faculty) and set to block automatically downloadable files or apply filtering by time of day.

Caching and performance.

Dell SonicWALL CFS is built around a website caching and rating architecture that allows administrators to block sites automatically by category for easier administration. The caching feature stores URL ratings locally on the Dell SonicWALL firewall, so response time is only a fraction of a second. In addition to filtering offensive Web content, CFS helps enhance performance by filtering out download sites for MP3s, streaming media, freeware and other files that consume tremendous amounts of bandwidth and are often the source of spyware and other malware.

Compliance and regulations.

A number of legislated regulations contain content filtering requirements that can be met using Dell SonicWALL CFS. For example, the Children's Internet Protection Act (CIPA) requires all schools and libraries that receive eRate funding to install content filtering. The flexibility of CFS, and the ability to set custom policies for different groups or different times of day, makes it ideal for educational settings. In addition, the reporting necessary to comply with these mandates can be fulfilled by Dell SonicWALL's Global Management System (GMS).

In addition to external regulation compliance, CFS is an integral part of internal compliance programs designed to reduce the liabilities that may incur when inappropriate content is allowed into the network. When Web access is unrestricted, not only is the result counter-productive, it can also result in costly lawsuits.

Visibility and reporting.

Dell SonicWALL CFS can allow customers to run granular reports summarizing Web access details. Both real-time and historical reports can be easily customized and delivered in a variety of formats. In addition to comprehensive graphical reports, users also can take advantage of "at-a-glance" reporting.

How it works.

Dell SonicWALL CFS is based on a rating architecture that relies on a dynamic database to block objectionable or inappropriate websites. CFS cross-references all websites as they are requested against a vast and highly accurate database of URLs, IP addresses and domains. The Dell SonicWALL appliance then receives a rating in real time, and compares that rating to the local policy setting. The appliance will then either allow or deny the request, based on locally configured policy.

Dell SonicWALL CFS has categorized over 20 million URLs, IP addresses and domains in a continuously updated, dynamically rated database, with thousands more added daily. Because the ratings are determined both by artificial intelligence and human observation, the database is highly accurate and the instance of false positives is minimized. The policy-based system allows the administrator to block all pre-defined categories or any combination of categories, and to apply these policies on a granular level. For example, if one group of users requires access to sites typically found within one category, this level of access can be granted while still denying access to other users.

Categories range from offensive types of content such as "Violence," which would include anti-social websites that advocate use of weapons or explosives, to sites that may not be offensive but would otherwise cause a potential risk to the network in terms of bandwidth usage, such as "Software downloads" or "Streaming Media/MP3."

Dell SonicWALL Application Intelligence and Control.

A tightly integrated feature of Dell SonicWALL Next Geneeration Firewalls, Dell SonicWALL Application Intelligence and Control monitors and displays application traffic in real time. This enables the creation of granular policy-based controls that identify and guarantee bandwidth to mission-critical applications while restricting or blocking non-productive applications. 

Deep security.

Dell SonicWALL’s Reassembly-Free Deep Packet Inspection™ (RFDPI) engine scans every byte of every packet delivering full content inspection of the entire stream while providing high performance and low latency. This technology is superior to outdated proxy designs that reassemble content using sockets bolted to anti-virus programs that are plagued with inefficiencies and overhead of socket memory thrashing that leads to high latency, low performance and file size limitations.

Network optimization.

Consolidating Dell SonicWALL Next-Generation Firewalls with Dell SonicWALL WAN Acceleration Appliance (WXA) Series solutions reduces the load traversing the network and can boost traffic productivity on the network by as much as 2X. Application-intelligent firewalls can also filter dangerous and non-productive traffic and forward only that traffic needing to be accelerated, thereby enhancing WAN performance.

Effortless deployment and management.

By merging comprehensive network security and control into a single platform, Dell SonicWALL reduces the time and complexity that comes with configuring, deploying and managing security solutions. Additionally, an innovative Web interface utilizes a complete suite of easy-to-use configuration wizards that guide users through the configuration steps for common user network environments or scenarios, for simple setup in any network environment.

Dell SonicWALL's management and reporting solutions provide a comprehensive architecture for centrally creating and managing security policies, providing real-time monitoring and alerts, and delivering intuitive compliance and usage reports, all from a single management interface. Whether your organization is a small- or medium-sized business, a distributed enterprise or a managed service provider, Dell™ SonicWALL™ offers software and appliance solutions to meet its needs.
