Q: What is your opinion of Fortinet's FortiGate Firewall?
The rising tendency towards all-in-one products sounds a good marketing idea, but when it comes to performance, there is a big gap. It is believed that when it comes to security there should be no negotiation and concession. With all in one box, perfectly synchronized with each other working synergistically, the product is bound to be appreciated. FortiOS released by Fortinet with its range of appliances offers good routing and encryption features by enhancing support for RIP I & II and OSPF.

Q: What is UTM?
Unified threat management (UTM) is a move toward security management that allows a network administrator to monitor and manage a wide variety of security-related applications and infrastructure components through a single management console. UTM appliances not only combines firewall, gateway anti-virus, and intrusion detection and prevention capabilities into a single platform but also works within themselves interdependently just like a piece of fabric.

Q: What is Security fabric?
Security Fabric uses FortiTelemetry to connect different security sensors and tools together to collect, coordinate, and respond to malicious behavior anywhere it occurs on the network in real time. The core of a security fabric is an upstream FortiGate located at the edge of the network, with several FortiGates functioning as Internet Segmentation Firewalls (ISFWs). A security fabric is used to coordinate with the behavior of other Fortinet products in the network, including FortiAnalyzer, FortiManager, FortiClient, FortiClient EMS, FortiWeb, FortiSwitch, and FortiAP.

Q: What is Threat Management?
Integrated threat management is a complete approach to network security issues that addresses multiple types of malware, as well as blended threats and spam, and protects from invasion not only at the gateway but also at the endpoint levels.

Q: What is Next Generation Firewall?
Next-Generation Firewall (NGFW) is the part of the third generation in firewall technology, combining a traditional firewall with other network device filtering functionalities, such as application firewall using in-line deep packet inspection system (DPI), an intrusion prevention system (IPS). Other techniques might also be employed, such as TLS/SSL encrypted traffic examination, website filtering, QoS/bandwidth management, antivirus scrutiny, and third-party identity management integration (i.e. LDAP, RADIUS, Active Directory)

Q: What is the difference between Next-Generation Firewall vs. Traditional Firewall?
NGFWs include typical functions of traditional firewalls such as packet filtering, network and port address translation (NAT), stateful monitoring, with virtual private network (VPN) support. The aim of next-generation firewalls is to include more layers of the OSI model, improving filtering of network traffic that is dependent on the packet contents. NGFWs perform deeper inspection compared to stateful inspection executed by the first and second-generation firewalls. NGFWs use a more thorough inspection approach, checking packet payloads and matching the signatures for harmful activities such as exploitable attacks and malware.

Q: Do you know about Fortinet as an Organization?
Fortinet is an American MNC with its headquarters in Sunnyvale, California. It develops and markets cybersecurity software, appliances, and services, such as firewalls, anti-virus, intrusion prevention, and endpoint security, among others.

Throughout the 2000s, Fortinet expanded its product lines, by adding products for wireless access points, sandboxing, and messaging security, among others.

Q: When inspecting and delivering email messages, what does a FortiMail unit do in a transparent mode?
First inspect viruses, then Inspect content of the message payload, then Inspect for spam, followed by performing a routing lookup to decide the next hop in MTA.

Q: What are the benefits of the Scalable feature in Fortinet Fabric?
Fortinet Security Fabric protects any organization from IoT to the Cloud. A complete security strategy needs both in-depth performances and in deep inspection along with the breadth i.e. end to end. Security not only needs to scale to meet volume and performance demands, it needs to scale itself up laterally, seamlessly tracking and securing data from IoT and endpoints, across the distributed network and data center, and into the cloud. Fortinet Security Fabric provides seamless, protection across the distributed Enterprise, as well as inspection of packet data, application protocols, and deep analysis of unstructured content at wire speeds.

Q: What does Aware mean in Fortinet Security fabric?
Security Fabric behaves as a single entity from a Policy and Logging perspective, enabling end-to-end segmentation in order to lessen the risk from advanced threats. We not only need to see data that flows into and out of the network but how that data pass through the network once it is inside the perimeter. Fortinet Security Fabric enables end-to-end network segmentation for deep visibility and inspection of traffic traveling the network, and controls who and what gets to go where thereby minimising the risk from advanced threats.

Q: What is the method FortiGate unit use to determine the availability of a web cache using wccp? (web cache communication protocol)
The web cache sends an “I see you” message, being fetched by the FortiGate unit.

Q: WAN optimization is, configured in active or passive mode, when will the remote peer accept an attempt to initiate a tunnel?
The attempt will be accepted when there is a matching WAN optimization passive rule.

Q: How does FortiMail Administrator Retrieve Email Account Information from a LDAP server instead of configuring this data manually on the unit?
The Configure of the LDAP profile sections “User query options” and “Authentication” then associates the profile to the domain, which is locally configured.

Q: When using sender reputation on a FortiMail unit, which actions can be taken against a source IP address generating spam or invalid E-mail messages?
1. FortiMail Delays the email messages from that source IP address with a temporary failure.
2. FortiMail Rejects the email messages from that source IP address with a permanent failure.
3. FortiMail Quarantines all the email messages from that source IP address

Q: What does the security feature of Fortinet Security Fabric benefit us?
Global and local risk intelligence and lessening information can be shared across individual products to decrease time to protect. Not only does security need to include powerful security tools for the various places and functions in the network, but true visibility and control needs these distinct elements work together as an integrated security system. Fortinet’s Security Fabric behaves as a single collaborative entity from a policy and logging perspective, allowing individual product elements to share global and local risk intelligence and risk mitigation information.

Q: What do we mean by Actionable in Fortinet Security Fabric?
Big Data cloud systems correlate risk information and network data to deliver into Actionable Threat Intelligence in real time. It is not enough to sense bad traffic or block malware using distinct security devices. Network administrators need a common set of risk intelligence and centralized orchestration that allows the security to dynamically adapt as a risk is revealed anywhere, not just in our network, but also anywhere in the world. Fortinet’s Big Data cloud systems centralize and correlate risk information and network data and provide actionable threat intelligence to each and every single security device in the network’s security fabric in real time.

Q: Why is the idea of a security fabric so important to network security in this current environment?
In this futuristic era, companies have to deal with a growing list of issues that put incredible strain on their security capabilities, including the Internet of Things, virtualization, SDN, a growing portfolio of interactive applications, and transitioning to cloud-based networking. They also have professionals who expect to be able to access work applications and data from anywhere, at any time, and on the same device, they use to manage their professional lives. Networks have evolved to accommodate these new requirements, becoming more complex, flexible, and powerful. At the same time, securing them has become a lot more complex as well.

Q: What distinguishes Fortinet’s security fabric approach from other vendors’ attempts at an integrated platform?
Fortinet distinguishes with other vendors with intentionally designed integration beginning with a unified operating system, highly optimized hardware and software processing with unmatched zero-day discovery, and a detection approach that combines behavioral detection, machine learning, and hardware virtualization. This allows the Fortinet Security Fabric to go beyond what is possible with a traditional signature-based approach to risk protection, or with siloed security technologies that vendors have begun to apparently stitch together using an overlay “platform” method.

Q: How does Fortinet’s Security Fabric benefit Fortinet’s global partner network of distributors and solution providers?
Because of its significant and complex character, security continues to be one of the largest opportunities for the channel. Partners that can plan, design, deploy and optimize an integrated security system are finding a growing demand for their skills. By combining the traditional security devices and emerging technologies together into an integrated security fabric, associates can help their customers collect and respond to intelligence that is more actionable, synchronize risk responses, and centralize the creation, distribution, and orchestration of their security management and further investigation. This wide visibility and open-standards approach offered by the Fortinet Security Fabric allows the solution providers to implement more automation to focus on the alerts, which matters the most in today’s world.

Q: How is Fortinet’s Fabric Ready Partner program different from the partner programs we see other vendors promoting?
Like many other partner programs, Fortinet’s Fabric Ready Partner Program brings together best-in-class technology alliance partners. Unlike other approaches, Fortinet’s approach actually allows the partners to deliver pre-integrated, end-to-end security offerings ready for deployment in any organization.
