Yateg User Data Security Conference

Yateg E-Commerce Co. user data security conference.
While there are many areas of overlap between cybersecurity (primarily securing internal network usage) and network security (primarily securing against external threats), the former is often defined as a subset of the latter. In the traditional “castle and moat” analogy with a perimeter-based approach to security – where your enterprise is the castle and the data stored within the castle are the crown jewels – cybersecurity is primarily concerned with security within the castle walls.

In this boundary-based scenario, the area within the castle walls can represent the company’s IT infrastructure, which includes its network components, hardware, operating systems, software and data storage. Network security protects these systems against malware/ransomware, distributed denial-of-service (DDoS) attacks, network intrusions and other attacks, creating a secure platform for users, computers and programs to perform their functions within the computing environment.

As organizations move to hybrid and multi-cloud environments, their data, applications and devices are dispersed across different locations and geographies. Users want to access enterprise systems and data from anywhere and on any device. As a result, traditional boundary-based approaches to network security are being eliminated. In a zero-trust security approach, organizations never trust and always authenticate access, and this approach is rapidly reinforcing new ways to improve an organization’s security posture.

Cybersecurity Defined
At a fundamental level, cybersecurity is the operation of protecting data, applications, devices and systems connected to the network.

Types of network security
Firewall protection
A firewall is a software program or hardware device that prevents unauthorized users from accessing your network by blocking suspicious traffic from entering and allowing legitimate traffic to pass through. There are several types of firewalls that vary in their level of security, from simple packet filtering firewalls to proxy servers to sophisticated next-generation firewalls that use AI and machine learning to compare and analyze the information trying to get through.

Understanding firewall security
Intrusion detection and prevention
Intrusion detection and prevention systems (IDPS) can be deployed directly behind a firewall to provide a second layer of defense against dangerous subjects. IDPS, which often works in conjunction with its predecessor, the more passive Intrusion Prevention System (IDS), sits between the source and destination addresses, creating additional suspension of traffic before it enters the network. Advanced IDPSs can even use machine learning and AI to immediately analyze incoming data and trigger automated processes when suspicious activity is detected, such as raising an alarm, blocking traffic from that source or resetting the connection.

Network Access Control (NAC)
Network access control is on the first line of defense and does just that: control access to your network. Commonly used as an “endpoint health check,” NAC scans endpoint devices (such as laptops or smartphones) to ensure they have the proper antivirus protection, the correct level of system updates, and are configured correctly before they can be accessed. NAC can also be programmed for “role-based access,” where users’ access is restricted based on their profile, so that once on the network they can only access approved files or data.

Cloud security
Cloud security protects online resources such as sensitive data, applications, virtualized IP addresses and services against compromise, loss or theft. Securing cloud-based systems requires robust security policies and layers of security methods such as firewall architecture, access control, virtual private networks (VPNs), data encryption or masking, threat intelligence software and disaster recovery procedures.

Virtual Private Networks (VPN)
A virtual private network (VPN) is software that protects users’ identities by encrypting their data and masking their IP address and location. When people use a VPN, they no longer connect directly to the Internet, but to a secure server that connects to the Internet on their behalf. VPNs are often used in businesses and are increasingly necessary for individuals, especially for people using public WiFi in coffee shops or airports. VPNs can protect users from hackers who can steal anything from emails, photos, credit card numbers and user identities.

Data Loss Prevention (DLP)
Data Loss Prevention (sometimes called “Data Leakage Prevention”) is a set of policies and tools to ensure that endpoint users do not accidentally or maliciously share sensitive information outside of a company’s network. To comply with government regulations on critical data (such as credit card, financial or health information), DLP policies and software are often used to monitor and control endpoint activity on corporate networks and in the cloud through alerts, encryption and other actions to protect data in motion, in use and at rest.

Endpoint protection
Endpoint security often requires a multi-layered approach to protect all network-connected endpoints: laptops, tablets, smartphones, wearables and other mobile devices. While endpoint protection can be a complex task, managed security services can help keep devices, data and the network safe with antivirus software, data loss prevention, encryption and other effective security measures.

Unified Threat Management (UTM)
With a UTM appliance, organizations can reduce costs and increase the manageability of network protection and monitoring through a variety of network security tools such as firewall, VPN, IDS, web content filtering and anti-spam software.

Secure Web Gateway
This security technology prevents unauthorized network traffic from entering the internal network and protects users and employees from accessing malicious websites containing viruses or malware. Secure Web Gateways typically include web filtering technology and security controls for web applications.

How does web security work?
At the most basic level, a secure network focuses on two basic principles: authentication and authorization. In other words, first, you must ensure that all network users are authenticated and authorized users, and second, you must authorize all network users to access the specified data they access.
