ECCouncil 312-50v13 Dumps Questions Answers

The scenario describes a method used to make a cryptographic key more secure by making it harder to brute-force. This process is called Key Stretching.

Key Stretching:

Takes a weak or short key and processes it through a function (often repeatedly) to produce a stronger, longer key.

Commonly used in password hashing (e.g., bcrypt, PBKDF2, scrypt).

Increases the computational time required to test each guess in a brute-force attack, effectively reducing attack feasibility.

Incorrect Options:

A. Key derivation function (KDF) is related but more general; key stretching is a specific technique often implemented within KDFs.

B. Key reinstallation is associated with WPA2 KRACK attacks.

C. Public key infrastructure (PKI) is a system of digital certificates, not a key strengthening technique.

Docker uses a client-server design. The docker client talks to the docker daemon, that will the work of building, running, and distributing your docker containers. The docker client and daemon will run on the same system, otherwise you will connect a docker consumer to a remote docker daemon. The docker consumer and daemon communicate using a REST API, over OS sockets or a network interface.

The docker daemon (dockerd) listens for docker API requests and manages docker objects like pictures, containers, networks, and volumes. A daemon may communicate with other daemons to manage docker services.

aLTEr attacks are usually performed on LTE devices Attacker installs a virtual (fake) communication tower between two authentic endpoints intending to mislead the victim This virtual tower is used to interrupt the data transmission between the user and real tower attempting to hijack the active session.

The new aLTEr attack can be used against nearly all LTE connected endpoints by intercepting traffic and redirecting it to malicious websites together with a particular approach for Apple iOS devices.

This attack works by taking advantage of a style flaw among the LTE network — the information link layer (aka: layer-2) of the LTE network is encrypted with AES-CTR however it’s not integrity-protected, that is why an offender will modify the payload.

As a result, the offender is acting a classic man-in-the-middle wherever they’re movement as a cell tower to the victim.
