What is Network Security?
Network Security is designed to protect your network and its data from multiple layers of breaches and intrusions with hardware and software solutions. Network Security is a vast and overarching term, and not just one thing, but is a broad term used to describe many different types of technology and various processes used to define a set of rules and configurations relating to network use, threats, accessibility, and overall threat protection.
Network Security typically consists of three different controls: physical, technical and administrative. Network Security involves access control, virus and antivirus software, application security, network analytics, many types of network-related security (endpoint, web, wireless), security gateways/firewalls, VPN encryption and many more.
Cloud-Based Storage is Network Security
Network Cloud security helps network users secure their network since Cloud security is more secure, more scalable, with reduced time to market, and usage-based costs. Traditional IT Security is onsite and can be associated with higher up-front management costs, slow scaling, with in-house data centers that can be more prone to cyber attack than cloud-based security.
Network Security has many layers of threat detection, including different types of firewall protection:
- Packet filtering: A small amount of data is analyzed and distributed according to the filter’s standards.
- Proxy service: Network security system that protects while filtering messages at the application layer.
- Stateful inspection: Dynamic packet filtering that monitors active connections to determine which network packets to allow through the Firewall.
- Next Generation Firewall: Deep packet inspection Firewall with application-level inspection.
Firewalls and Your Network
Firewalls control incoming and outgoing traffic on networks, with predetermined security rules. Firewalls keep out unfriendly traffic and is a necessary part of daily computing. Network Security relies heavily on Firewalls, and especially Next Generation Firewalls, which focus on blocking malware and application-layer attacks.
Hyperscale Network Security
Hyperscale is the ability of an architecture to scale appropriately, as increased demand is added to the system. This solution includes rapid deployment and automated management capabilities that make scaling out simple and hassle free for businesses of all sizes. By tightly integrating networking and compute resources in a software-defined system, we can fully utilize all hardware resources available to us.
What is Access Control?
Access control is controlling who can access your network and knowing which devices belong in order to weed out the devices that do not belong, and may be threats. Recognizing what devices belong on the network will better enable the network administrator to enforce security policies.
Robust Network Security Will Protect Against:
- Virus: A virus is a malicious, downloadable file that can lay dormant that replicates itself by changing other computer programs with its own code. Once it spreads those files are infected and can spread from one computer to another, and/or corrupt or destroy network data.
- Worms: Can slow down computer networks by eating up bandwidth as well as the slow the efficiency of your computer to process data. A worm is a standalone malware that can propagate and work independently of other files, where a virus needs a host program to spread.
- Trojan: A trojan is a backdoor program that creates an entryway for malicious users to access the computer system by using what looks like a real program, but quickly turns out to be harmful. A trojan virus can delete files, activate other malware hidden on your computer network, such as a virus and steal valuable data.
- Spyware: Much like its name, spyware is a computer virus that gathers information about a person or organization without their express knowledge and may send the information gathered to a third party without the consumer’s consent.
- Adware: Can redirect your search requests to advertising websites and collect marketing data about you in the process so that customized advertisements will be displayed based on your search and buying history.
- Ransomware: This is a type of trojan cyberware that is designed to gain money from the person or organization’s computer on which it is installed by encrypting data so that it is unusable, blocking access to the user’s system.
Network Security is vital in protecting client data and information, it keeps shared data secure, protects from viruses and helps with network performance by reducing overhead expenses and costly losses from data breaches, and since there will be less downtime from malicious users or viruses, it can save businesses money in the long-term.
