An intrusion detection system (IDS) is a device or software application that monitors a network or systems for malicious activity or policy violations. Any intrusion activity or violation is typically either reported to an administrator or collected centrally using a security information and event management (SIEM) system. A SIEM system combines outputs from multiple sources and uses alarm filtering techniques to distinguish malicious activity from false alarms.
An application firewall is a form of firewall that controls input/output or system calls of an application or service. It operates by monitoring and blocking communications based on a configured policy, generally with predefined rule sets to choose from. The two primary categories of application firewalls are network-based and host-based.
Cisco PIX was a popular IP firewall and network address translation (NAT) appliance. It was one of the first products in this market segment.
Fortinet, Inc. is a cybersecurity company with headquarters in Sunnyvale, California. The company develops and sells security solutions like firewalls, endpoint security and intrusion detection systems. Fortinet has offices located all over the world.
A security appliance is any form of server appliance that is designed to protect computer networks from unwanted traffic.
A virtual security appliance is a computer appliance that runs inside virtual environments. It is called an appliance because it is pre-packaged with a hardened operating system and a security application and runs on a virtualized hardware. The hardware is virtualized using hypervisor technology delivered by companies such as VMware, Citrix and Microsoft. The security application may vary depending on the particular network security vendor. Some vendors such as Reflex Systems have chosen to deliver Intrusion Prevention technology as a Virtualized Appliance, or as a multifunctional server vulnerability shield delivered by Blue Lane. The type of security technology is irrelevant when it comes to the definition of a Virtual Security Appliance and is more relevant when it comes to the performance levels achieved when deploying various types of security as a virtual security appliance. Other issues include visibility into the hypervisor and the virtual network that runs inside.
TriGeo Network Security is a United States–based provider of security information and event management (SIEM) technology. The company helps mid market organizations proactively, protects networks and data from internal and external threats, with a SIEM appliance that provides real-time log management and automated network defense - from the perimeter to the endpoint.
In computing, managed security services (MSS) are network security services that have been outsourced to a service provider. A company providing such a service is a managed security service provider (MSSP) The roots of MSSPs are in the Internet Service Providers (ISPs) in the mid to late 1990s. Initially, ISP(s) would sell customers a firewall appliance, as customer premises equipment (CPE), and for an additional fee would manage the customer-owned firewall over a dial-up connection.
A distributed firewall is a security application on a host machine of a network that protects the servers and user machines of its enterprise's networks against unwanted intrusion. A firewall is a system or group of systems that implements a set of security rules to enforce access control between two networks to protect the "inside" network from the "outside" network. They filter all traffic regardless of its origin—the Internet or the internal network. Usually deployed behind the traditional firewall, they provide a second layer of defense. The advantages of the distributed firewall allow security rules (policies) to be defined and pushed out on an enterprise-wide basis, which is necessary for larger enterprises.
In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet.
Messaging Security is a program that provides protection for companies' messaging infrastructure. The programs includes IP reputation-based anti-spam, pattern-based anti-spam, administrator defined block/allow lists, mail antivirus, zero-hour malware detection and email intrusion prevention.
Deep content inspection (DCI) is a form of network filtering that examines an entire file or MIME object as it passes an inspection point, searching for viruses, spam, data loss, key words or other content level criteria. Deep Content Inspection is considered the evolution of Deep Packet Inspection with the ability to look at what the actual content contains instead of focusing on individual or multiple packets. Deep Content Inspection allows services to keep track of content across multiple packets so that the signatures they may be searching for can cross packet boundaries and yet they will still be found. An exhaustive form of network traffic inspection in which Internet traffic is examined across all the seven OSI ISO layers, and most importantly, the application layer.
DDoS mitigation is a set of network management techniques and/or tools, for resisting or mitigating the impact of distributed denial-of-service (DDoS) attacks on networks attached to the Internet, by protecting the target, and relay networks. DDoS attacks are a constant threat to businesses and organizations, by delaying service performance, or by shutting down a website entirely.
Cyberoam Technologies, a Sophos subsidiary, is a global network security appliances provider, with presence in more than 125 countries.
A next-generation firewall (NGFW) is a part of the third generation of firewall technology, combining a conventional firewall with other network device filtering functions, such as an application firewall using in-line deep packet inspection (DPI), an intrusion prevention system (IPS). Other techniques might also be employed, such as TLS-encrypted traffic inspection, website filtering, QoS/bandwidth management, antivirus inspection, third-party identity management integration, and SSL decryption
Endian Firewall is an open-source router, firewall and gateway security Linux distribution developed by the South Tyrolean company Endian. The product is available as either free software, commercial software with guaranteed support services, or as a hardware appliance.
Endpoint security or endpoint protection is an approach to the protection of computer networks that are remotely bridged to client devices. The connection of endpoint devices such as laptops, tablets, mobile phones, and other wireless devices to corporate networks creates attack paths for security threats. Endpoint security attempts to ensure that such devices follow compliance to standards.
Data center security is the set of policies, precautions and practices adopted at a data center to avoid unauthorized access and manipulation of its resources. The data center houses the enterprise applications and data, hence why providing a proper security system is critical. Denial of service (DoS), theft of confidential information, data alteration, and data loss are some of the common security problems afflicting data center environments.
WatchGuard, formally known as WatchGuard Technologies, Inc, is an American technology company based in Seattle, Washington. It specializes in network security solutions aimed at safeguarding computer networks from external threats such as malware and ransomware.
A secure access service edge (SASE) is technology used to deliver wide area network (WAN) and security controls as a cloud computing service directly to the source of connection rather than a data center. It uses cloud and edge computing technologies to reduce the latency that results from backhauling all WAN traffic over long distances to one or a few corporate data centers, due to the increased movement off-premises of dispersed users and their applications. This also helps organizations support dispersed users.
