The Common Vulnerability Scoring System (CVSS) is a free and open industry standard for assessing the severity of computer system security vulnerabilities. CVSS attempts to assign severity scores to vulnerabilities, allowing responders to prioritize responses and resources according to threat. Scores are calculated based on a formula that depends on severalmetrics that approximate ease of exploit and the impact of exploit. Scores range from 0 to 10, with 10 being the most severe. While many utilize only the CVSS Base score for determining severity, Temporal and Environmental scores also exist, to factor in availability of mitigations and how widespread vulnerable systems are within an organization, respectively.

The current version of CVSS is CVSSv3.0, released in June 2015

Tor

Tor is free software for enabling anonymous communication. The name is an acronym derived from the original software project name The Onion Router,[7] however the correct spelling is “Tor”, capitalizing only the first letter.[8] Tor directs Internet traffic through a free, worldwide, volunteer network consisting of more than seven thousand relays[9] to conceal a user’s … Continue reading Tor

Tor is free software for enabling anonymous communication. The name is an acronym derived from the original software project name The Onion Router,[7] however the correct spelling is “Tor”, capitalizing only the first letter.[8] Tor directs Internet traffic through a free, worldwide, volunteer network consisting of more than seven thousand relays[9] to conceal a user’s location and usage from anyone conducting network surveillance or traffic analysis. Using Tor makes it more difficult for Internet activity to be traced back to the user: this includes “visits to Web sites, online posts, instant messages, and other communication forms”.[10] Tor’s use is intended to protect the personal privacy of users, as well as their freedom and ability to conduct confidential communication by keeping their Internet activities from being monitored.

Onion routing is implemented by encryption in the application layer of a communication protocol stack, nested like the layers of anonion. Tor encrypts the data, including the destination IP address, multiple times and sends it through a virtual circuit comprising successive, randomly selected Tor relays. Each relay decrypts a layer of encryption to reveal only the next relay in the circuit in order to pass the remaining encrypted data on to it. The final relay decrypts the innermost layer of encryption and sends the original data to its destination without revealing, or even knowing, the source IP address. Because the routing of the communication is partly concealed at every hop in the Tor circuit, this method eliminates any single point at which the communicating peers can be determined through network surveillance that relies upon knowing its source and destination.

An adversary might try to de-anonymize the user by some means. One way this may be achieved is by exploiting vulnerable software on the user’s computer.[11] The NSA has a technique that targets outdated Firefox browsers codenamed EgotisticalGiraffe,[12] and targets Tor users in general for close monitoring under its XKeyscore program.[13] Attacks against Tor are an active area of academic research,[14][15] which is welcomed by the Tor Project itself.[16]

Computer emergency response teams (CERT)

Computer emergency response teams (CERT) are expert groups that handle computer security incidents. Alternative names for such groups include computer emergency readiness team and computer security incident response team (CSIRT). The name “Computer Emergency Response Team” was first used by the CERT Coordination Center (CERT-CC) at Carnegie Mellon University (CMU). The abbreviation CERT of the … Continue reading Computer emergency response teams (CERT)

Computer emergency response teams (CERT) are expert groups that handle computer security incidents. Alternative names for such groups include computer emergency readiness team and computer security incident response team (CSIRT).

The name “Computer Emergency Response Team” was first used by the CERT Coordination Center (CERT-CC) at Carnegie Mellon University (CMU). The abbreviation CERT of the historic name was picked up by other teams around the world. Some teams took on the more specific name of CSIRT to point out the task of handling computer security incidents instead of other tech support work, and because CMU was threatening to take legal action against individuals or organisations who referred to any other team than CERT-CC as a CERT. After the turn of the century, CMU relaxed its position, and the terms CERT and CSIRT are now used interchangeably.

The history of CERTs is linked to the existence of malware, especially computer worms and viruses. Whenever a new technology arrives, its misuse is not long in following. The first worm in the IBM VNET was covered up. Shortly after, a worm hit the Internet on 3 November 1988, when the so-called Morris Worm paralysed a good percentage of it. This led to the formation of the first computer emergency response team at Carnegie Mellon University under U.S. Government contract. With the massive growth in the use of information and communications technologies over the subsequent years, the now-generic term ‘CERT’/’CSIRT’ refers to an essential part of most large organisations’ structures. In many organisations the CERT evolves into a information security operations center.
