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.
Antivirus software, also known as anti-malware, is a computer program used to prevent, detect, and remove malware.
Network security consists of the policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, which is controlled by the network administrator. Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Network security covers a variety of computer networks, both public and private, that are used in everyday jobs: conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access. Network security is involved in organizations, enterprises, and other types of institutions. It does as its title explains: it secures the network, as well as protecting and overseeing operations being done. The most common and simple way of protecting a network resource is by assigning it a unique name and a corresponding password.
Snort is a free open source network intrusion detection system (IDS) and intrusion prevention system (IPS) created in 1998 by Martin Roesch, founder and former CTO of Sourcefire. Snort is now developed by Cisco, which purchased Sourcefire in 2013.
Cisco PIX was a popular IP firewall and network address translation (NAT) appliance. It was one of the first products in this market segment.
A host-based intrusion detection system (HIDS) is an intrusion detection system that is capable of monitoring and analyzing the internals of a computing system as well as the network packets on its network interfaces, similar to the way a network-based intrusion detection system (NIDS) operates. HIDS focuses on more granular and internal attacks through focusing monitoring host activities instead of overall network traffic. HIDS was the first type of intrusion detection software to have been designed, with the original target system being the mainframe computer where outside interaction was infrequent.
Check Point Integrity is an endpoint security software product developed by Check Point Software Technologies. It is designed to protect personal computers and the networks they connect to from computer worms, Trojan horses, spyware, and intrusion attempts by hackers. The software aims to stop new PC threats and attacks before signature updates have been installed on the PC. The software includes.
Cisco Security Agent (CSA) was an endpoint intrusion prevention system software made originally by Okena, which was bought by Cisco Systems in 2003.
Data loss prevention (DLP) software detects potential data breaches/data exfiltration transmissions and prevents them by monitoring, detecting and blocking sensitive data while in use, in motion, and at rest.
Sourcefire, Inc was a technology company that developed network security hardware and software. The company's Firepower network security appliances were based on Snort, an open-source intrusion detection system (IDS). Sourcefire was acquired by Cisco for $2.7 billion in July 2013.
Network behavior anomaly detection (NBAD) is a security technique that provides network security threat detection. It is a complementary technology to systems that detect security threats based on packet signatures.
Symantec Endpoint Protection, developed by Broadcom Inc., is a security software suite that consists of anti-malware, intrusion prevention and firewall features for server and desktop computers.
Martin Roesch founded Sourcefire in 2001 and was its Chief Technology Officer until the company was acquired by Cisco Systems on October 7, 2013 for $2.7B. Roesch now is CEO of Netography which raised $45M in Series A funding in November 2021. A respected authority on intrusion prevention, detection technology, and forensics, he was responsible for the technical direction and product development efforts of Sourcefire and Cisco Security before he moved into board roles and VC roles with Decibel Partners. Martin, has industry experience in network security and embedded systems engineering. He is also the author and lead developer of the Snort Intrusion Prevention and Detection System which formed the foundation for the Sourcefire firewall and IDS/IPS systems. Snort is still developed by Cisco Systems today and remains the most-used open source IDS technology.
Cisco Security Monitoring, Analysis, and Response System (MARS) was a security monitoring tool for network devices. Together with the Cisco Security Manager (CSM) product, MARS made up the two primary components of the Cisco Security Management Suite.
Comodo Internet Security (CIS) is developed and distributed by Comodo Group, a freemium Internet security suite that includes an antivirus program, personal firewall, sandbox, host-based intrusion prevention system (HIPS) and website filtering.
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.
In network security, evasion is bypassing an information security defense in order to deliver an exploit, attack, or other form of malware to a target network or system, without detection. Evasions are typically used to counter network-based intrusion detection and prevention systems but can also be used to by-pass firewalls and defeat malware analysis. A further target of evasions can be to crash a network security defense, rendering it in-effective to subsequent targeted attacks.
User behavior analytics (UBA) or user and entity behavior analytics (UEBA), is the concept of analyzing the behavior of users, subjects, visitors, etc. for a specific purpose. It allows cybersecurity tools to build a profile of each individual's normal activity, by looking at patterns of human behavior, and then highlighting deviations from that profile that may indicate a potential compromise.
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.
Cisco Talos, or Cisco Talos Intelligence Group, is a cybersecurity technology and information security company based in Fulton, Maryland. It is a part of Cisco Systems Inc. Talos' threat intelligence powers Cisco Secure products and services, including malware detection and prevention systems. Talos provides Cisco customers and internet users with customizable defensive technologies and techniques through several of their own open-source products, including the Snort intrusion prevention system and ClamAV anti-virus engine.
