Cloud computing. Cloud computing metaphor: For a user, the network elements representing the provider-rendered services are invisible, as if obscured by a cloud. Cloud computing is a computing term or metaphor that evolved in the late 1990s, based on utility and consumption of computer resources. Cloud computing involves application systems which are executed within the cloud and operated through internet enabled devices.
Purely cloud computing does not rely on the use of cloud storage as it will be removed upon users download action. Clouds can be classified as public, private and hybrid.[1][2] Overview[edit] Cloud computing[3] relies on sharing of resources to achieve coherence and economies of scale, similar to a utility (like the electricity grid) over a network.[2] At the foundation of cloud computing is the broader concept of converged infrastructure and shared services.
Cloud computing, or in simpler shorthand just "the cloud", also focuses on maximizing the effectiveness of the shared resources. Securelink.
Wireless LAN. VisualRF Heatmap. AirWave lets IT manage the application and device experience on several generations of multivendor networks. (That means you can manage Cisco networks better than Cisco.) Unlike traditional port-based management, AirWave employs a user-centric approach, identifying who is on the network, where they are accessing the network, the mobile devices they’re using, and how much bandwidth is being consumed by specific devices. With visibility into everything that affects wireless and mobility service-level agreements (SLAs), AirWave lets you proactively plan for capacity, visualize client performance and troubleshoot application issues before you get a helpdesk ticket. With AirWave, your entire distributed enterprise – from campuses to branch offices around town and around the world – are easily and efficiently managed from a single pane of glass, making it easy to keep your SLAs on track.
APM Mgt Platform. RAPIDS Rogue Detection. Controllers. Mobility Access Switches extend security and operational simplicity to wired networks by extending role-based access to wired users and devices. In addition to built-in Layer 2, Layer 3, site-to-site VPN, and authentication capabilities, Mobility Access Switches forever eliminate traditional IT overhead required by legacy switches in the access network by employing the same role-based access policies for wired and wireless. The result is a far simpler and more cost-effective wired access network that gives users consistent and secure access to network resources, no matter where they are, what device they’re using or how they connect. Mobility Access Switches are available in three models. Unique Features: Mobility-centric wired solution Unlike legacy switches that utilize VLANs and ports, Mobility Access Switches apply policies to wired users and devices based on contextual data – user roles, device types, application flows and location.

Diagram of a public key infrastructure A public key infrastructure (PKI) is a set of hardware, software, people, policies, and procedures needed to create, manage, distribute, use, store, and revoke digital certificates.[1] In cryptography, a PKI is an arrangement that binds public keys with respective user identities by means of a certificate authority (CA). The user identity must be unique within each CA domain. The third-party validation authority (VA) can provide this information on behalf of CA. The binding is established through the registration and issuance process, which, depending on the assurance level of the binding, may be carried out by software at a CA or under human supervision. The PKI role that assures this binding is called the registration authority (RA), which ensures that the public key is bound to the individual to which it is assigned in a way that ensures non-repudiation.
[citation needed] Design[edit] A PKI consists of:[4][6][7] Methods of certification[edit] Two-factor authentication. Two-step verification (also known as Two-factor authentication, abbreviated to TFA) is a process involving two stages to verify the identity of an entity trying to access services in a computer or in a network.
This is a special case of a multi-factor authentication which might involve only one of the three authentication factors (a knowledge factor, a possession factor, and an inherence factor) for both steps.[1][2][3] If each step involves a different authentication factor then the two-step authentication is additionally two-factor authentication. Example[edit] To provide an everyday example: an automated teller machine (ATM) typically requires two-factor verification. To prove that users are who they claim to be, the system requires two items: an ATM smartcard (application of the possession factor) and the personal identification number (PIN) (application of the knowledge factor).
Google's two-step verification process[edit] The first step is to log in using the username and password. RSA. Imprivata. Kerberos. Kerberos is een standaard authenticatieprotocol dat ervoor zorgt dat gebruikers van een netwerk zich op een veilige manier kunnen aanmelden en hun identiteit kunnen bewijzen, zonder zich telkens opnieuw te moeten aanmelden. Kerberos maakt een beperkte vorm van Single Sign-on mogelijk. De Kerberos functie betekent dat een Kerberos server aan een ingelogde gebruiker een ticket toekent. Dit ticket blijft gedurende de hele sessie geldig en wordt vertrouwd door andere servers die het protocol kennen.
Als de gebruiker uitlogt, wordt de sessie afgebroken en is het ticket niet langer geldig. Het kerberos protocol schematisch weergegeven Op het eerste gezicht is Kerberos een ingewikkeld protocol, maar deze opzet is bewust gekozen om de overhead voor alle partijen zo veel mogelijk te minimaliseren. Eigenschappen van het protocol zijn: De gebruiker gebruikt zijn gebruikersnaam en wachtwoord om te bewijzen wie hij is. Een gebruiker geeft zijn gebruikersnaam en wachtwoord aan de Kerberos client.

Our Application Command Center (ACC) is an interactive, graphical summary of the applications, users, URLs, threats, and content traversing your network. It allows you to keep your finger on the pulse of what is going on. ACC provides a 10,000 foot view of what's happening on your network, and with just a few clicks you can get a highly detailed view to learn more, including links to the specific policy that allowed a certain behavior so you can tune it as needed.
Knowledge is power. Learning more about new or unfamiliar applications or threats that are displayed in ACC takes just a single click, which shows you: A description of the application or threat.An application's key features and behavioral characteristics.Details on the users using an application.Details on those affected by a threat. PA Product Overview. Our innovative security platform is based on our next-generation firewall which natively classifies all traffic, inclusive of applications, threats and content, then ties that traffic to the user, regardless of location or device type.
The application, content, and user – the core elements that run your business – are then used as the basis of your security policies. This unique ability empowers you to safely enable applications, make informed decisions on network access, and strengthen your network security. Regardless of where your applications, users, and content may be, they almost always run across the network – which is the logical place to secure them.
Deploy our innovative network security products to secure users (e.g., Internet gateways, branch offices, mobile users) as well as services (e.g., virtualized datacenters, virtualized desktop infrastructures, websites). Policy Management. App-ID graphically displays the applications that are traversing your network. It allows you to see who is using applications and the potential security risks. This information empowers you to quickly deploy application-, application function-, and port-based enablement policies in a systematic and controlled manner. Your policies may range from open (allow), to moderate (enabling certain applications or functions, then scan, or shape, schedule, etc.), to closed (deny).
Examples may include: Allow or denyAllow based on schedule, users, or groupsApply traffic shaping through QoSAllow certain application functions such as file transfer within instant messagingAllow, but scan for viruses and other threatsDecrypt and inspectApply policy-based forwardingAny combination of the above.

Web Security Gateway. Bluecoat. Secure Web Gateway. Get real-time security that’s effective, not reactive. Web security threats are seemingly endless. But of all the malicious schemes today, the dynamic web link is one of the most powerful tools for cybercrime and web threat delivery. Malware engineers have learned how to use dynamic web links to bypass traditional reputation filters and commonly blocked web categories. So if your business still relies on AV update cycles to prevent real-time malware attacks, it’s time to revisit your security strategy. While existing AV solutions can effectively protect against known threats, only a real-time web defense can block threats from dynamic web links.
That’s why Blue Coat combines web filtering and DLP solutions with a cloud-based community web defense that unites millions of users and analyzes real-time ratings of dynamic links and unrated content. Why walk through the woods alone at night when you can have over 70 million people with you? IronPort Web Security Appliances. S160. S360. S660. SenderBase Network. Threat Operations Center.
