350-701 Dumps - Implementing and Operating Cisco Security Core Technologies (SCOR 350-701) Practice Exam Questions

The primary goal of network security is to protect data and resources from unauthorized access, misuse, or damage. It ensures the confidentiality, integrity, and availability of information while allowing legitimate users to safely access the network.

• Confidentiality: Ensuring information is only accessible to authorized users.
• Integrity: Maintaining the accuracy and trustworthiness of data.
• Availability: Ensuring that information and resources are available to authorized users when needed.

A firewall is a network security device or software that monitors and controls incoming and outgoing network traffic based on defined security rules. It protects networks by blocking unauthorized access while allowing legitimate communications, preventing attacks like hacking or malware infiltration.

• Symmetric encryption: Uses a single key to encrypt and decrypt data. Fast but requires secure key sharing.
• Asymmetric encryption: Uses a public key to encrypt and a private key to decrypt data. More secure for exchanging sensitive information online.

A zero-day exploit is a cyberattack that takes advantage of a software vulnerability unknown to the software vendor. Because no fix or patch exists yet, attackers can exploit it before it is discovered or resolved.

MFA is a security method that requires users to provide two or more verification factors to access an account or system. Examples include a password plus a fingerprint or a password plus a one-time code sent to a mobile device. MFA significantly reduces the risk of unauthorized access.

Network segmentation divides a larger network into smaller segments or subnetworks. It improves security by limiting access between segments, containing potential attacks, and improving traffic management. This is especially important in enterprise networks.

• IDS: Monitors network traffic to detect suspicious activity or attacks but does not block it automatically.
• IPS: Monitors and actively prevents attacks by blocking or mitigating malicious traffic. Both systems are essential for network security monitoring.

RBAC is a method of restricting network or system access based on a user’s role within an organization. Each role has specific permissions, ensuring users only access what is necessary for their job, which reduces security risks.

Continuous monitoring allows organizations to detect threats and vulnerabilities in real-time, ensuring security policies are enforced and risks are managed. It helps prevent breaches, ensures compliance, and improves overall network resilience.
