What is Network security solution?
Network security solution is an advanced platform or set of tools that can help detecting threats and protecting computer networks from cyber attacks and breaches. Different solutions focus on securing different aspects of the network and leverage different technological approaches to preventing the infiltration of unauthorized persons or entities.
XACTA leverages wide range of unique technologies and threat intelligence to offer holistic security from the perimeter to the network core.
A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Firewall establishes a network perimeter that attempts to block any unauthorized access to data and resources inside the network perimeter.
Performs stateful inspection at the destination layer of the network model, the source IP, the protocol and the port of data packets to determine whether to grant or deny access.
Operates at the application layer of the network model. It detects and blocks malicious application traffic by performing deep packet inspection (DPI) and blocking packets according to the destination application.
A network administration solution that controls which devices can connect to the network. It identifies devices using MAC addresses or certificates and enables connectivity for approved devices only.
NAC is effective as a security control in a traditional network perimeter, accessed by managed devices from an office location. It is less effective for modern IT environment with remote access, personal devices access and connections to and from resources to in public Cloud.
Provides secure network access to individual hosts such as mobile users, extranet consumers, and telecommuters. It may provide hosts with VPN client software or offer a web-based client.
A remote access VPN offers various mechanisms to maintain the integrity and privacy of sensitive data including data encryption and multi-factor authentication (MFA). However, in model IT environment, VPNs are not considered secure as they grant access to the entire network and do not allow granular network permissions.
Involves breaking the network into smaller segments consisting of common functions, risks, or organizational roles. Network segmentation can also help segment areas within the network to improve access control and security.
A perimeter gateway, for example, segments a corporate network from the Internet. It blocks external threats to sensitive data within the segment.
IPS helps detecting and preventing various network security threats such as:
- Vulnerability exploitation
- Denial of Service (DoS),
- Brute force attacks.
Threat attackers often have time to exploit vulnerability between the announcement and the release of a patch. An IPS can block these attacks quickly.
Ensures that each user receives the necessary access privileges—there is no implicit trust. Organizations use ZTNA solutions to create by micro-perimeters around each resource or application in the network and implement granular access control.
Users connect to the network via ZTNA that uses multi-factor authentication (MFA) to verify their identity and scan the endpoint compliance. ZTNA solution assesses multiple parameters such as time. Location … etc. to determine if the requested action should be enabled
Administrators define access rules and ZTNA implements these rules by assessing all connection requests. This approach prevents the unnecessary exposure of sensitive systems and minimizes network risks.
SASE is an enterprise networking category which aims to simplify enterprise networking in a distributed IT environment. SASE is a unified, cloud-native networking service that integrates SD-WAN and network security solutions such as firewall as a service (FWaaS), cloud security access broker (CASB), secure web gateway (SWG), and zero trust network access (ZTNA).
SASE, organizations can simplify operations, reduce costs, and support agile development. This reduces time to market and enables organizations to respond to changing business conditions and market conditions.
