Snort (software)
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. In 2009, Snort entered InfoWorld's Open Source Hall of Fame as one of the "greatest ieces ofopen source software of all time". Uses Snort's open-source network-based intrusion detection/prevention system (IDS/IPS) has the ability to perform real-time traffic analysis and packet logging on Internet Protocol (IP) networks. Snort performs protocol analysis, content searching and matching. The program can also be used to detect probes or attacks, including, but not limited to, operating system fingerprinting attempts, semantic URL attacks, buffer overflows, server message block probes, and stealth port scans. Snort can be configured in three main modes: 1. sniffer, 2. packet logger, and 3. network intrusion detection. Sniffer Mod ...

Buffer Overflow
In information security and programming, a buffer overflow, or buffer overrun, is an anomaly whereby a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory locations. Buffers are areas of memory set aside to hold data, often while moving it from one section of a program to another, or between programs. Buffer overflows can often be triggered by malformed inputs; if one assumes all inputs will be smaller than a certain size and the buffer is created to be that size, then an anomalous transaction that produces more data could cause it to write past the end of the buffer. If this overwrites adjacent data or executable code, this may result in erratic program behavior, including memory access errors, incorrect results, and crashes. Exploiting the behavior of a buffer overflow is a well-known security exploit. On many systems, the memory layout of a program, or the system as a whole, is well defined. By sending in data designed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Security Software
Computer security software or cybersecurity software is any computer program designed to influence information security. This is often taken in the context of defending computer systems or data, yet can incorporate programs designed specifically for subverting computer systems due to their significant overlap, and the adage that the best defense is a good offense. The defense of computers against intrusion and unauthorized use of resources is called ''computer security''. Similarly, the defense of computer networks is called ''network security''. The subversion of computers or their unauthorized use is referred to using the terms ''cyberwarfare'', ''cybercrime'', or '' security hacking'' (later shortened to ''hacking'' for further references in this article due to issues with ''hacker'', ''hacker culture'' and differences in white/grey/black 'hat' color identification). Types Below, various software implementations of Cybersecurity patterns and groups outlining ways a host syst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zeek
Zeek is a free and open-source software network analysis framework. Vern Paxson began development work on Zeek in 1995 at Lawrence Berkeley National Lab. Zeek is a network security monitor (NSM) but can also be used as a network intrusion detection system (NIDS). The Zeek project releases the software under the BSD license. Output Zeek's purpose is to inspect network traffic and generate a variety of logs describing the activity it sees. A complete list of log files is available at the project documentation site. Log example The following is an example of one entry in JSON format from the conn.log: Threat hunting One of Zeek's primary use cases involves cyber threat hunting. Name Dr. Paxson originally named the software "Bro" as a warning regarding George Orwell's Big Brother from the novel ''Nineteen Eighty-Four''. In 2018 the project leadership team decided to rename the software. At LBNL in the 1990s, the developers ran their sensors as a pseudo-user named “zeek”, ...

List Of Free And Open-source Software Packages
This is a list of free and open-source software packages, computer software licensed under free software licenses and open-source licenses. Software that fits the Free Software Definition may be more appropriately called free software; the GNU project in particular objects to their works being referred to as open-source. For more information about the philosophical background for open-source software, see free software movement and Open Source Initiative. However, nearly all software meeting the Free Software Definition also meets ''the Open Source Definition'' and vice versa. A small fraction of the software that meets either definition is listed here. Some of the open-source applications are also the basis of commercial products, shown in the List of commercial open-source applications and services.

Ruby On Rails
Ruby on Rails (simplified as Rails) is a server-side web application framework written in Ruby under the MIT License. Rails is a model–view–controller (MVC) framework, providing default structures for a database, a web service, and web pages. It encourages and facilitates the use of web standards such as JSON or XML for data transfer and HTML, CSS and JavaScript for user interfacing. In addition to MVC, Rails emphasizes the use of other well-known software engineering patterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), and the active record pattern. Ruby on Rails' emergence in 2005 greatly influenced web app development, through innovative features such as seamless database table creations, migrations, and scaffolding of views to enable rapid application development. Ruby on Rails' influence on other web frameworks remains apparent today, with many frameworks in other languages borrowing its ideas, including Dja ...
