Cyber Threat Hunting
In information security, threat hunting is the process of proactively searching for threats against computer systems in order to protect them. This is in contrast to traditional threat management measures, such as firewalls, intrusion detection systems (IDS), malware sandbox (computer security) and SIEM systems, which typically involve an investigation of evidence-based data ''after'' there has been a warning of a potential threat. Threat analyst Lesley Carhart stated that there is no consensus amongst practitioners what threat hunting actually entails. Methodologies Overview Recently, the world has seen a rise in the number and severity of cyber attacks, data breaches, malware infections, and online fraud incidents. According to cyber security and ai company SonicWall, the number of ransomware attacks grew by 105% globally. Major corporations around the world have fallen victim to high-profile data breaches, with the average cost of a data breach now estimated at $4.24 mill ...

Information Security
Information security is the practice of protecting information by mitigating information risks. It is part of information risk management. It typically involves preventing or reducing the probability of unauthorized or inappropriate access to data or the unlawful use, Data breach, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information. It also involves actions intended to reduce the adverse impacts of such incidents. Protected information may take any form, e.g., electronic or physical, tangible (e.g., Document, paperwork), or intangible (e.g., knowledge). Information security's primary focus is the balanced protection of data confidentiality, data integrity, integrity, and data availability, availability (also known as the 'CIA' triad) while maintaining a focus on efficient policy implementation, all without hampering organization productivity. This is largely achieved through a structured risk management process. To stand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indicator Of Compromise
Indicator of compromise (IoC) in computer forensics is an artifact observed on a network or in an operating system that, with high confidence, indicates a computer intrusion. Types of indication Typical IoCs are virus signatures and IP addresses, MD5 hashes of malware files, or URLs or domain names of botnet command and control servers. After IoCs have been identified via a process of incident response and computer forensics, they can be used for early detection of future attack attempts using intrusion detection systems and antivirus software. Automation There are initiatives to standardize the format of IoC descriptors for more efficient automated processing. Known indicators are usually exchanged within the industry, where the Traffic Light Protocol is being used.

Bug Bounty Program
A bug bounty program is a deal offered by many websites, organizations, and software developers by which individuals can receive recognition and compensation for reporting bugs, especially those pertaining to security vulnerabilities. If no financial reward is offered, it is called a vulnerability disclosure program. These programs, which can be considered a form of crowdsourced penetration testing, grant permission for unaffiliated individuals—called bug bounty hunters, white hats or ethical hackers—to find and report vulnerabilities. If the developers discover and patch bugs before the general public is aware of them, cyberattacks that might have exploited are no longer possible. Participants in bug bounty programs come from a variety of countries, and although a primary motivation is monetary reward, there are a variety of other motivations for participating. Hackers could earn much more money for selling undisclosed zero-day vulnerabilities to brokers, spyware co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Europe, The Middle East And Africa
Europe, the Middle East and Africa, commonly known by its acronym EMEA among the North American business spheres, is a geographical region used by institutions, governments and global spheres of marketing, media and business when referring to this region. The acronym EMEA is a shorthand way of referencing the two continents (Africa and Europe) and the Middle Eastern sub-continent all at once. As the name suggests, the region includes all of the countries found on the continents of Africa and Europe, as well as the countries that make up the Middle East. The region is generally accepted to include all European nations and all African nations, and extends east to Iran, including part of Russia. Typically, the acronym does not include overseas territories of mainland countries in the region, such as French Guiana. However, the term is not completely clear, and while it usually refers to Europe, the Middle East and Africa, it is not uncommon for businesses and other institutions to ...

Americas
The Americas, sometimes collectively called America, are a landmass comprising the totality of North America and South America.''Webster's New World College Dictionary'', 2010 by Wiley Publishing, Inc., Cleveland, Ohio. When viewed as a single continent, the Americas or America is the 2nd largest continent by area after Asia, and is the 3rd largest continent by population. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World. Along with their Lists of islands of the Americas, associated islands, the Americas cover 8% of Earth's total surface area and 28.4% of its land area. The topography is dominated by the American Cordillera, a long chain of mountains that runs the length of the west coast. The flatter eastern side of the Americas is dominated by large river basins, such as the Amazon basin, Amazon, St. Lawrence River–Great Lakes, Mississippi River System, Mississippi, and Río de la Plata Basin, La Plata basins.

Data Collection
Data collection or data gathering is the process of gathering and measuring information on targeted variables in an established system, which then enables one to answer relevant questions and evaluate outcomes. Data collection is a research component in all study fields, including physical science, physical and social sciences, humanities, and business. While methods vary by discipline, the emphasis on ensuring accurate and honest collection remains the same. The goal for all data collection is to capture evidence that allows data analysis to lead to the formulation of credible answers to the questions that have been posed. Regardless of the field of or preference for defining data (Quantitative method, quantitative or Qualitative method, qualitative), accurate data collection is essential to maintain research integrity. The selection of appropriate data collection instruments (existing, modified, or newly developed) and delineated instructions for their correct use reduce the l ...

Cyberattack
A cyberattack (or cyber attack) occurs when there is an unauthorized action against computer infrastructure that compromises the confidentiality, integrity, or availability of its content. The rising dependence on increasingly complex and interconnected computer systems in most domains of life is the main factor that causes vulnerability to cyberattacks, since virtually all computer systems have bugs that can be exploited by attackers. Although it is impossible or impractical to create a perfectly secure system, there are many defense mechanisms that can make a system more difficult to attack, making information security a field of rapidly increasing importance in the world today. Perpetrators of a cyberattack can be criminals, hacktivists, or states. They attempt to find weaknesses in a system, exploit them and create malware to carry out their goals, and deliver it to the targeted system. Once installed, the malware can have a variety of effects depending on its purpose. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
