Self-signed certificates are certificates that are signed by the entity they belong to, rather than being signed by a trusted third-party certificate authority (CA). The primary risk associated with the use of self-signed certificates is that they are not trusted by default.
A retinal scan is a biometric identification method that uses unique patterns of blood vessels in the retina to identify individuals. It is primarily used for identification purposes, such as in security systems, but it is not typically used as an authenticator. An authenticator is a method used to verify an individual's identity trying to access a system or resource.
Risk mitigation is a risk management strategy that involves taking actions to reduce or mitigate the impact or likelihood of risks. In this case, Mike implemented an intrusion prevention system (IPS) to block common network attacks from affecting his organization. The IPS is a proactive measure that aims to detect and prevent network attacks before they can cause damage or compromise the network. By implementing the IPS, Mike is pursuing a risk mitigation strategy to reduce the risk associated with network attacks.
Ethernet uses a bus topology, which means that all devices on the network are connected to a single shared communication line, called the Ethernet cable or Ethernet bus. Each device on the network can send and receive data on this shared medium.
When a security incident is detected in progress on a network, the highest priority for Tara should be containment. Containment involves taking immediate actions to isolate and limit the impact of the security incident. The goal is to prevent further spread of the incident within the network and minimize potential damage.
Physical infrastructure hardening refers to measures taken to strengthen the security and resilience of physical components of an organization's infrastructure. It involves implementing safeguards to protect physical assets from threats such as natural disasters, physical attacks, or accidents.
John the Ripper is a popular password cracking tool used for testing the security of passwords. On a Linux system, the password-related information is stored in the /etc/passwd and /etc/shadow files.
