System and Network Security

Network Segmentation

Network segmentation defines boundaries between network segments where assets within the group have a common function, risk or role within an organization. For instance, the perimeter gateway segments a company network from the Internet. Potential threats outside the network are prevented, ensuring that an organization’s sensitive data remains inside. Organizations can go further by defining additional internal boundaries within their network, which can provide improved security and access control.

Remote Access VPN

Remote access VPN provides remote and secure access to a company network to individual hosts or clients, such as telecommuters, mobile users, and extranet consumers. Each host typically has VPN client software loaded or uses a web-based client. Privacy and integrity of sensitive information is ensured through multi-factor authentication, endpoint compliance scanning, and encryption of all transmitted data

Intrusion Prevention Systems (IPS)

IPS technologies can detect or prevent network security attacks such as brute force attacks, Denial of Service (DoS) attacks and exploits of known vulnerabilities. A vulnerability is a weakness for instance in a software system and an exploit is an attack that leverages that vulnerability to gain control of that system. When an exploit is announced, there is often a window of opportunity for attackers to exploit that vulnerability before the security patch is applied. An Intrusion Prevention System can be used in these cases to quickly block these attacks.

Mobile device security

Cybercriminals are increasingly targeting mobile devices and apps. Within the next three years, 90 percent of IT organizations may support corporate applications on personal mobile devices. Of course, you need to control which devices can access your network. You will also need to configure their connections to keep network traffic private.

Web security

A web security solution will control your staff's web use, block web-based threats, and deny access to malicious websites. It will protect your web gateway on site or in the cloud. "Web security" also refers to the steps you take to protect your own website.

Sandboxing

Sandboxing is a cybersecurity practice where you run code or open files in a safe, isolated environment on a host machine that mimics end-user operating environments. Sandboxing observes the files or code as they are opened and looks for malicious behavior to prevent threats from getting on the network. For example malware in files such as PDF, Microsoft Word, Excel and PowerPoint can be safely detected and blocked before the files reach an unsuspecting end user.

Anti-virus and anti-malware software

"Malware," short for "malicious software," includes viruses, worms, Trojans, ransomware, and spyware. Sometimes malware will infect a network but lie dormant for days or even weeks. The best antimalware programs not only scan for malware upon entry, but also continuously track files afterward to find anomalies, remove malware, and fix damage.

Cloud Network Security

Applications and workloads are no longer exclusively hosted on-premises in a local data center. Protecting the modern data center requires greater flexibility and innovation to keep pace with the migration of application workloads to the cloud. Software-defined Networking (SDN) and Software-defined Wide Area Network (SD-WAN) solutions enable network security solutions in private, public, hybrid and cloud-hosted Firewall-as-a-Service (FWaaS) deployments.
