Lesson 16

The process of strengthening the security settings and defenses of network devices, servers, and workstations to protect against unauthorized access, data breaches, and other potential threats.

Harden Devices

The pre-configured passwords that come with network devices, which should be changed immediately to prevent unauthorized access.

Default Passwords

User accounts on network devices that are not actively used or needed, which should be removed to reduce the risk of unauthorized access.

Unnecessary Logins

A policy that requires users to create complex passwords with a combination of uppercase and lowercase letters, numbers, and special symbols, and to change their passwords regularly to enhance security.

Strong Password Policy

Optional features or services installed on network devices that are not actively used, which should be disabled or removed to minimize the risk of potential attacks.

Unnecessary Services

The process of regularly updating devices with the latest security patches and software updates to address known vulnerabilities and protect against potential exploits.

Patch Management

The ability to physically interact with a device, which can potentially lead to unauthorized access or manipulation. Limiting physical access is crucial for maintaining security.

Physical Access

A network that is deemed safe and authorized, typically the internal network of an organization, from which changes to network devices are allowed.

Trusted Network

The implementation of encryption protocols, such as WPA2 or WPA3, to secure wireless network traffic and prevent unauthorized interception of data.

Encryption for Wireless Networks

The process of monitoring and reviewing access logs and records to identify suspicious activity, detect breaches, and conduct forensic analysis of security incidents.

Audit Access

The creation and storage of copies of device configurations and data to ensure data recovery in the event of misconfiguration, attacks, or device failures.
