Many have questioned the usefulness of security questions. [5] [6] [7] Security specialist Bruce Schneier points out that since they are public facts about a person, they are easier to guess for hackers than passwords. Users that know this create fake answers to the questions, then forget the answers, thus defeating the purpose and creating an ...
[1] The simplest example of a challenge-response protocol is password authentication, where the challenge is asking for the password and the valid response is the correct password. An adversary who can eavesdrop on a password authentication can authenticate themselves by reusing the intercepted password. One solution is to issue multiple ...
An illustrative example of a breach in namespace security occurred with the hacking of the United States Securities and Exchange Commission's (SEC) X account. The account was compromised due to the apparent lack of two-factor authentication (2FA), [ 7 ] a basic but critical layer of security that requires a second form of verification in ...
In computer science, robustness is the ability of a computer system to cope with errors during execution [1] [2] and cope with erroneous input. [2] Robustness can encompass many areas of computer science, such as robust programming, robust machine learning, and Robust Security Network.
As with any security measure, passwords vary in strength; some are weaker than others. For example, the difference in strength between a dictionary word and a word with obfuscation (e.g. letters in the password are substituted by, say, numbers — a common approach) may cost a password-cracking device a few more seconds; this adds little strength.
Internet security awareness or Cyber security awareness refers to how much end-users know about the cyber security threats their networks face, the risks they introduce and mitigating security best practices to guide their behavior. [1] [2] End users are considered the weakest link and the primary vulnerability within a network.
A password policy is a set of rules designed to enhance computer security by encouraging users to employ strong passwords and use them properly. A password policy is often part of an organization's official regulations and may be taught as part of security awareness training. Either the password policy is merely advisory, or the computer ...
SIEMs are security solutions that help organizations and security teams analyze “log data in real-time for swift detection of security incidents.” [13] SIEMS are not the only examples of detective controls. There are also Physical security controls, Intrusion detection systems, and anti-virus/anti-malware tools, which all have different ...
