[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 ...
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 ...
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.
The following outline is provided as an overview of and topical guide to computer security: . Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data, as well as from the ...
1) When considering the current digital control system designs, the cyber security of these systems is dependent upon what is considered border protections, i.e., firewalls, passwords, etc. If a malicious actor compromised the digital control system for an industrial operation by a man-in-the-middle attack , data can be corrupted with the ...
[5] In 2023, Martin Thomson and David Schinazi argued that Postel's robustness principle actually leads to a lack of robustness, including security: [6] A flaw can become entrenched as a de facto standard. Any implementation of the protocol is required to replicate the aberrant behavior, or it is not interoperable.
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 ...
For example, reducing the complexity and functionality of the system is effective at reducing the attack surface. [ 35 ] Successful vulnerability management usually involves a combination of remediation (closing a vulnerability), mitigation (increasing the difficulty, and reducing the consequences, of exploits), and accepting some residual risk.
