Softwares can be used for automatic password sniffing. An Event is an action that a program can detect. A meeting with international law experts at the Munich Security Conference recently highlighted the need for greater norms development in cyberspace. Source: NIPP 2013 Partnering for Critical Infrastructure Security and Resilience. A pressure regulator is a device used to control the pressure of a gas or liquid. It is a form of buffer that holds the intermediate results of an operation or data that is awaiting processing. The stored information(e.g. A blended attack is a hostile action with the intent of spreading malicious code. The main functions of intrusion prevention systems are to identify malicious activity, log information about this activity, attempt to block/stop it, and report it. Any access that violates the stated security policy. An independent professional security review that tests and examines a company's compliance with existing controls, the results of which enable an auditor to recommend necessary changes in security controls, policies and procedures. They sometimes work in tandem to do maximum damage (Blended Threat). Standard Access Control Lists (ACLs) are essentially a set of commands, grouped together by a number or name that is used to filter traffic entering or leaving an interface. other terms commonly used include emergency shutdown system (ess), safety shutdown system (ssd), and safety interlock system (sis). Antivirus software relies on a constantly updated and evolving database of virus digital footprint signatures to detect any virus that may have infected a system. It is a computer networking device that connects devices together on a computer network by using packet switching to receive, process and forward data to the destination device. A form of filtering that blocks only websites specified as harmful. Identity management, risk management and incident management form the crux of cyber security strategies of an organization. A field site is a subsystem that is identified by physical, geographical, or logical segmentation within the ICS. The DMZ is a segment of a network where servers accessed by less trusted users are isolated. It is an exploitation of a valid computer session, sometimes also called a session key, to gain unauthorised access to sensitive information or services in a computer system or network. to 192.168.255.255 (192.168/16 prefix). Malicious code describes a broad category of system security terms that includes attack scripts, viruses, worms, trojan horses, backdoors, and other malicious active content. A cryptographic algorithm that uses a single key (i.e., a secret key) for both encryption and decryption. Trust determines which permissions and what actions other systems or users can perform on remote machines. Permutation is a process where the letters within a text are kept the same, but the position changes to scramble the message. The policy also sets guidelines on how the network should be used. What makes a rootkit particularly lethal is the ability to erase tracks and mask the intrusion from the vulnerable system, allowing the attacker to navigate the entire network without being noticed. This is done by sending a SYN (synchronization) packet, as if to initiate a three-way handshake, to every port on the server. However, investigation resources like forensic tools, dirty networks, quarantine networks and consultation with law enforcement may be useful for the effective and rapid resolution of an emergency incident. 45 Main Cyber Security Terms Everyone Must Know. It allows the auditor to trace a piece of information to its origin and to reconstruct past system activities.
