The SANS Institute is a private U.S. for-profit company founded in 1989 that specializes in information security, cybersecurity training, and selling certificates. Topics available for training include cyber and network defenses, penetration testing, incident response, digital forensics, and auditing. The information security courses are developed through a consensus process involving administrators, security managers, and information security professionals. The courses cover security fundamentals and technical aspects of information security. The institute has been recognized for its training programs and certification programs. Per 2021, SANS is the world’s largest cybersecurity research and training organization. SANS is an acronym for SysAdmin, Audit, Network, and Security.
An intrusion detection system 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.
Computer forensics is a branch of digital forensic science pertaining to evidence found in computers and digital storage media. The goal of computer forensics is to examine digital media in a forensically sound manner with the aim of identifying, preserving, recovering, analyzing and presenting facts and opinions about the digital information.
Security event management (SEM), and the related SIM and SIEM, are computer security disciplines that use data inspection tools to centralize the storage and interpretation of logs or events generated by other software running on a network.
Threat modeling is a process by which potential threats, such as structural vulnerabilities or the absence of appropriate safeguards, can be identified and enumerated, and countermeasures prioritized. The purpose of threat modeling is to provide defenders with a systematic analysis of what controls or defenses need to be included, given the nature of the system, the probable attacker's profile, the most likely attack vectors, and the assets most desired by an attacker. Threat modeling answers questions like "Where am I most vulnerable to attack?", "What are the most relevant threats?", and "What do I need to do to safeguard against these threats?".
Network forensics is a sub-branch of digital forensics relating to the monitoring and analysis of computer network traffic for the purposes of information gathering, legal evidence, or intrusion detection. Unlike other areas of digital forensics, network investigations deal with volatile and dynamic information. Network traffic is transmitted and then lost, so network forensics is often a pro-active investigation.
Security information and event management (SIEM) is a field within the field of computer security, where software products and services combine security information management (SIM) and security event management (SEM). SIEM is the core component of any typical Security Operations Center (SOC), which is the centralized response team addressing security issues within an organization.
In computer security, a threat is a potential negative action or event facilitated by a vulnerability that results in an unwanted impact to a computer system or application.
A cyberattack is any offensive maneuver that targets computer information systems, computer networks, infrastructures, personal computer devices, or smartphones. An attacker is a person or process that attempts to access data, functions, or other restricted areas of the system without authorization, potentially with malicious intent. Depending on the context, cyberattacks can be part of cyber warfare or cyberterrorism. A cyberattack can be employed by sovereign states, individuals, groups, societies or organizations and it may originate from an anonymous source. A product that facilitates a cyberattack is sometimes called a cyber weapon. Cyberattacks have increased over the last few years. A well-known example of a cyberattack is a distributed denial of service attack (DDoS).
Georgios (George) V. Magklaras is a computer scientist working as a Senior Computer Systems Engineer at the Norwegian Meteorological Institute, in Norway. He also co-founded Steelcyber Scientific, an information security based consultancy specialising in digital forensics. He is a high-performance computing engineer and information security researcher. He developed methods in the field of insider IT misuse detection and prediction and digital forensics. He is the author of the LUARM and POFR tools for the Linux Operating System. He has been a strong advocate of Linux, open source tools and the Perl programming language and has given a series of lectures internationally in the fields of intrusion detection systems, digital forensics, bioinformatics, computer programming and systems administration.
Threat Intelligence Platform (TIP) is an emerging technology discipline that helps organizations aggregate, correlate, and analyze threat data from multiple sources in real time to support defensive actions. TIPs have evolved to address the growing amount of data generated by a variety of internal and external resources (such as system logs and threat intelligence feeds) and help security teams identify the threats that are relevant to their organization. By importing threat data from multiple sources and formats, correlating that data, and then exporting it into an organization’s existing security systems or ticketing systems, a TIP automates proactive threat management and mitigation. A true TIP differs from typical enterprise security products in that it is a system that can be programmed by outside developers, in particular, users of the platform. TIPs can also use APIs to gather data to generate configuration analysis, Whois information, reverse IP lookup, website content analysis, name servers, and SSL certificates.
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, Internet-of-things devices, and other wireless devices to corporate networks creates attack paths for security threats. Endpoint security attempts to ensure that such devices follow a definite level of compliance to standards.
The Co-Managed IT security service model entails security monitoring, event correlation, incident response, system tuning, and compliance support across an organization's entire IT environment. Co-Management allows organizations to collaborate with their managed security service providers by blending security expertise of the provider with the contextual knowledge of the customer to optimise security posture.
Cyber threat intelligence (CTI) is knowledge, skills and experience-based information concerning the occurrence and assessment of both cyber and physical threats and threat actors that is intended to help mitigate potential attacks and harmful events occurring in cyberspace. Cyber threat intelligence sources include open source intelligence, social media intelligence, human Intelligence, technical intelligence, device log files, forensically acquired data or intelligence from the internet traffic and data derived for the deep and dark web.
Active defense can refer to a defensive strategy in the military or cybersecurity arena.
Cyber threat hunting is a proactive cyber defence activity. It is "the process of proactively and iteratively searching through networks to detect and isolate advanced threats that evade existing security solutions." This is in contrast to traditional threat management measures, such as firewalls, intrusion detection systems (IDS), malware sandbox and SIEM systems, which typically involve an investigation of evidence-based data after there has been a warning of a potential threat.
In cybersecurity, cyber self-defense refers to self-defense against cyberattack. While it generally emphasizes active cybersecurity measures by computer users themselves, cyber self-defense is sometimes used to refer to the self-defense of organizations as a whole, such as corporate entities or entire nations. Surveillance self-defense is a variant of cyber self-defense and largely overlaps with it. Active and passive cybersecurity measures provide defenders with higher levels of cybersecurity, intrusion detection, incident handling and remediation capabilities. Various sectors and organizations are legally obligated to adhere to cyber security standards.
The Center for Internet Security (CIS) is a US 501(c)(3) nonprofit organization, formed in October 2000. Its mission statement professes that the function of CIS is to " help people, businesses, and governments protect themselves against pervasive cyber threats."
Identity threat detection and response (ITDR) is a cybersecurity discipline that includes tools and best practices to protect identity management infrastructure from attacks. ITDR can block and detect threats, verify administrator credentials, respond to various attacks, and restore normal operations. Common identity threats include phishing, stolen credentials, insider threats, and ransomware.
Network detection and response (NDR) refers to a category of network security products that detect abnormal system behaviors by continuously analyzing network traffic. NDR solutions apply behavioral analytics to inspect raw network packets and metadata for both internal (east-west) and external (north-south) network communications.
