A network and communications security solution can reduce the risk of data theft and sabotage at work. Network security makes it easier to protect your workstations against spyware. It also protects shared information. The job of a cybersecurity professional involves a lot of network and communication security. This article will discuss the sixth domain of SSCP Network and Communications Security and what you can expect from the SSCP exam.

Domains of SSCP

These are the seven SSCP domains:
Domain 1: Access Controls (16%)
Domain 2: Security Operations and Administration (15%)
Domain 3: Risk Identification Monitoring and Analysis (15%)
Domain 4: Incident Response and Recovery (13%).
Domain 5: Cryptography (10%)
Domain 6: Network and Communications Security (16%)
Domain 7: Systems and Application Security (15%)
Domain 6: Network and Communications Security
Domain 6 in the SSCP certification exam consists of Network and Communications Security. The Network and Communications Security domain has a 16% weightage in the SSCP exam. This domain will introduce network models, hardware devices, and the structure of data flowing through these devices. IT networks are made up of various hardware devices that are assembled in different ways to create topologies, which are network model. Network devices use telecommunications signaling system to transmit data between users. This area will include wireless and cellular technology as well as the Bring Your Own Device concept. It also includes the connection of personal digital devices to the work network. It will also include convergent network communications such as voice and multimedia across a digital network and prioritizing data that travels over a network. The following subtopics are covered in Network and Communications Security domain:
Learn and apply the fundamental concepts of networking
Countermeasures and understanding network attacks
Control network access
Network security: Manage it
Configure and operate network-based security devices
Configure and operate wireless technologies

1. Understanding and applying the Fundamental Concepts of NetworkingThis section will give you an in-depth understanding of the fundamental concepts and then introduce the design and implementation for network devices, protocols and telecommunication services that allow data to be transferred through public and private networks. It will cover the OSI, TCP/IP, and VPN technologies in detail. This section will discuss network topologies and the various topologies such as bus, star, and ring. Network hardware and access points include firewalls, routers and switches, gateways and proxy servers. It will also include the most commonly used ports, protocols, and data transmission media types, such as coaxial, fiber optic, and twisted-pair cables.
2. Understanding Network Attacks and Countermeasures. This section will explain how to set up network security devices, and recognize different types of network attacks. This section will cover the methods of preventing network-based attacks, detecting intrusions and using countermeasures to combat such attacks. This section will also include ARP, brute force and worms, flooding. Eavesdropping, sniffers. Dos/DDOS and Spoofing.
3. Manage Network Access ControlsThis section will describe the different network access control systems and how to manage them. It will also explain how to use them to protect data and system security using various confidentiality, integrity, availability, and availability levels. It will discuss the various network access control protocols and standards. This section will cover understanding and working with remote access technology, including TACACS and RADIUS, as well as basic network theory, operating information, and basic network theory. This section also covers security essentials
